The Intel Core i5-13400T paired with an NVIDIA GeForce RTX 4090 is a desktop combination that pairs a low-power, efficiency-focused 10-core processor with the fastest consumer GPU of its generation. There are no measured FPS rows for this exact combination in the data, so all frame rate discussion here is estimated from the individual benchmark scores of each component rather than direct testing. The data shows a CPU at the 60th percentile among all processors and a GPU at the 88th percentile among all GPUs, with a combined percentile of 74. That gap in percentile rank—28 points—is the first clue that this is not a balanced pairing for most workloads, and the benchmark scores confirm that the GPU will be waiting on the CPU in many scenarios.

GPU Analysis — VRAM, bandwidth, clocks, RT/tensor hardware, what the benchmark scores mean for rendering

The NVIDIA GeForce RTX 4090 is built on the Ada Lovelace architecture using a 5 nm process at TSMC, with a chip designated AD102 containing 76,300 million transistors on a 609 mm² die. That transistor density of 125.3M per mm² is among the highest in the consumer market, and it shows in the raw specifications. The GPU has 16,384 shading units, 512 texture mapping units, and 176 raster operations pipelines, which drive a pixel rate of 443.5 GPixel/s and a texture rate of 1,290.2 GTexel/s. The FP32 compute rating is 82.58 TFLOPS, and the FP16 rating is identical at 82.58 TFLOPS with a 1:1 ratio, meaning the card does not rely on shader recompilation for half-precision work—useful for AI inference and some rendering tasks that use FP16.

Memory is a defining feature: 24 GB of GDDR6X on a 384-bit bus delivers 1.01 TB/s of bandwidth. That figure is more than twice what most 8 GB or 12 GB cards offer, and it matters for 4K textures, large scenes, and GPU compute workloads that exceed VRAM capacity on smaller cards. The memory clock is listed as 1313 MHz with 21 Gbps effective data rate. The base clock is 2235 MHz and the boost clock is 2520 MHz, which are relatively high for a GPU of this size, though the thermal and power envelope is substantial at a TDP of 450 W.

For ray tracing and tensor work, the RTX 4090 has 128 RT cores and 512 tensor cores. These are the dedicated hardware units that accelerate ray-traced lighting and DLSS-style AI upscaling. The benchmark scores reflect this capability: the GPU scores 9,223 in 3DMark Steel Nomad DX12, 255,416 in GeekBench OpenCL, and 271,631 in GeekBench Vulkan. The PassMark G3D score is 38,194, and the PassMark GPU compute score is 26,613. In DirectX 11 and DirectX 12 PassMark tests, the scores are 326 and 150 respectively, which are lower than the DirectX 9 score of 397—these are synthetic API-specific tests and not indicative of real-world regression, as modern games use DX12 and Vulkan where the 3DMark and GeekBench scores show much stronger results. The GPU sits at the 88th percentile among all GPUs, with an average benchmark score of 60,347.

Comparing to nearest rivals, the RTX 4090's average score is essentially tied with the Intel Arc Pro A60 (0% delta), 0.3% ahead of the AMD Radeon Pro Vega 48, 2.5% ahead of the AMD Radeon Pro W6600M, and 2.9% behind the AMD Radeon PRO V710. These are professional workstation cards, not gaming GPUs, which suggests the 4090's score is being measured across a broad benchmark suite that includes compute-heavy tests where workstation cards also perform well. In gaming-specific workloads, the 4090's 24 GB VRAM and 1.01 TB/s bandwidth would typically place it far ahead, but the data does not include gaming FPS numbers for this pairing.

For rendering, the implications are clear. The FP32 throughput of 82.58 TFLOPS means GPU-based renderers that use single-precision math will see high performance. The 24 GB VRAM allows loading scenes that would spill over on 16 GB cards, and the 1.01 TB/s bandwidth ensures texture streaming keeps up with the shading rate. RT cores and tensor cores accelerate hybrid rendering pipelines that mix rasterization with ray tracing and AI denoising. The 3DMark Steel Nomad score of 9,223 is a DX12 test that stresses overall GPU throughput, and it indicates the card can handle modern engine workloads at high settings.

Balance and Bottleneck — which component limits which workload, using percentiles and FPS scaling as evidence

The core issue with this pairing is the mismatch between CPU and GPU performance tiers. The i5-13400T has a 60th percentile rank among all CPUs, while the RTX 4090 is at the 88th percentile. In gaming, where frame rates are often limited by the CPU at lower resolutions or by the GPU at higher resolutions, this means the CPU will be the bottleneck in many scenarios. The i5-13400T's Cinebench R23 multi-core score is 17,029 and single-core is 2,404, while the R20 scores are 7,152 multi-core and 1,009 single-core. The single-core performance is what matters most for frame pacing in games, and a score of 2,404 in R23 single-core is respectable but not class-leading—it is below what high-end desktop CPUs achieve, and the RTX 4090 is capable of producing frame rates that exceed what this CPU can feed in CPU-bound titles.

In GPU-bound workloads like 4K gaming or heavy ray tracing, the RTX 4090 will be the limiting factor, which is expected because the GPU is doing the heavy lifting. But at 1080p or 1440p with lower graphics settings, the CPU will cap the frame rate. The data does not include measured FPS for this pairing, so exact scaling is unknown, but the percentile gap suggests that in esports titles or older games with high frame rates, the i5-13400T will hold back the 4090. In modern AAA games at 1440p or 4K with maximum settings, the GPU becomes the bottleneck and the CPU's lower single-core score is less impactful.

For productivity, the balance shifts. The CPU's 10 cores and 16 threads with a base clock of 1300 MHz and boost of 4.40 GHz produce a GeekBench multi-core score of 10,227 and single-core of 1,899. These are mid-range numbers. The GPU's compute performance—82.58 TFLOPS FP32 and 26,613 PassMark GPU compute—will dominate any task that can use GPU acceleration, such as video encoding, 3D rendering with CUDA, or scientific compute. In these cases, the CPU is not the bottleneck because the GPU does the parallel work. However, in tasks that are single-threaded or lightly threaded, like software compilation or some office applications, the CPU's single-core score of 1,899 in GeekBench will limit overall responsiveness.

The combined percentile of 74 reflects that the average of the two components is lower than the GPU's rank alone. This is a pairing where the GPU is overqualified relative to the CPU for gaming, but the CPU is adequate for GPU-accelerated productivity. The bottleneck will be situational: CPU in low-resolution gaming and light-threaded apps, GPU in high-resolution gaming and parallel compute.

CPU Analysis — cores, clocks, architecture, what the benchmark scores mean for real workloads

The Intel Core i5-13400T is a Raptor Lake-S part on the Intel Socket 1700 platform, built on a 10 nm process at Intel with a die size of 215 mm². It has 10 cores and 16 threads, which indicates a hybrid arrangement of performance and efficiency cores—the core count and thread count are consistent with a 6+4 configuration, though the data does not specify the exact split. The base clock is 1300 MHz, which is very low, and the boost clock is 4.40 GHz. The 35 W TDP is the defining feature of this CPU: it is a T-series low-power part designed for thermals and power efficiency rather than raw performance. The cache hierarchy includes 80 KB of L1 per core, 1.25 MB of L2 per core, and 20 MB of shared L3 cache.

The low base clock is notable. At 1300 MHz, the CPU idles at a very low frequency, which helps keep power consumption down, but it means that sustained workloads will rely heavily on the boost behavior to reach 4.40 GHz. The benchmark scores show what this CPU can do when boosting: Cinebench R15 multi-core scores 1,716 and single-core 242; R20 scores 7,152 multi-core and 1,009 single-core; R23 scores 17,029 multi-core and 2,404 single-core. GeekBench multi-core is 10,227 and single-core is 1,899. The average benchmark score is 5,210.

Comparing to nearest rivals, the i5-13400T is essentially tied with the Intel Xeon E-2378G (0.2% higher), 0.6% behind the Intel Core i9-10850K, 0.6% behind the Intel Core i7-11700B, and 0.8% behind the Intel Core i5-14401E. These are all older or similar-generation parts, and the deltas are small—under 1%. This means the i5-13400T performs very close to an i9-10850K in average benchmark scores, despite having a much lower TDP. The 35 W TDP is a fraction of what those other CPUs consume, so the efficiency is impressive, but the absolute performance is still mid-range.

For real workloads, the multi-core scores suggest this CPU can handle moderate multi-threaded tasks like video encoding, compiling, or running virtual machines, but it will not be a top-tier workstation CPU. The single-core scores are more telling for day-to-day use: a GeekBench single-core of 1,899 and R23 single-core of 2,404 are good for office work, web browsing, and light productivity, but they are not sufficient to keep up with a flagship GPU in high-refresh gaming. The 20 MB L3 cache helps with game performance by keeping more data on-chip, and the 10 nm process keeps power draw low, but the core clock ceiling of 4.40 GHz limits single-thread throughput.

Usage Scenarios — grounded in the scores: high-refresh gaming, streaming, video editing, 3D rendering, software development, student and office work. One short paragraph per scenario, citing the numbers that support the verdict

High-refresh gaming: At 1080p or 1440p with high refresh rates, the i5-13400T will be the limiting factor. The GPU's 88th percentile rank and 3DMark Steel Nomad score of 9,223 indicate it can produce very high frame rates, but the CPU's single-core Cinebench R23 score of 2,404 is below what is needed to feed those frames in CPU-bound titles. Expect frame rates to be capped by the CPU in esports and older games, while the GPU sits underutilized. At 4K, the GPU becomes the bottleneck and the pairing is more balanced, but the CPU's lower percentile still means it will struggle to maintain maximum frame pacing.

Streaming: The RTX 4090's tensor cores and NVENC encoder—implied by the Ada Lovelace architecture—make GPU-based streaming efficient, and the 24 GB VRAM provides headroom for simultaneous game capture and encoding. The CPU's 10 cores and 16 threads are enough to handle OBS overhead and chat applications alongside the game, though the low base clock of 1300 MHz means the CPU will rely on boosting to 4.40 GHz to avoid hitches. The multi-core GeekBench score of 10,227 indicates adequate parallel throughput for streaming tasks.

Video editing: Software that uses GPU acceleration will see strong performance from the RTX 4090's 82.58 TFLOPS FP32 and PassMark GPU compute score of 26,613. Timeline scrubbing, effects, and exports will be GPU-bound, and the 24 GB VRAM allows working with high-resolution footage without memory pressure. The CPU's Cinebench R23 multi-core score of 17,029 handles non-GPU tasks like audio processing and project management, but it is not a bottleneck in GPU-accelerated workflows.

3D rendering: This is where the pairing shines. GPU renderers like Blender Cycles or Octane will use the 4090's CUDA cores and RT cores, and the 16,384 shading units will process complex scenes quickly. The FP32 throughput of 82.58 TFLOPS is the key metric, and the 24 GB VRAM prevents out-of-memory errors on large scenes. The CPU's R23 multi-core score of 17,029 is sufficient for scene preparation and physics, but the rendering itself will be GPU-bound, making the CPU's lower percentile less relevant.

Software development: Compiling code is typically multi-threaded but not necessarily GPU-accelerated. The i5-13400T's 10 cores and 16 threads with a GeekBench multi-core score of 10,227 will handle moderate compilation tasks, but the 35 W TDP means sustained boost clocks may be lower than a higher-TDP CPU. The RTX 4090 is overkill for development, but it does enable local GPU testing for machine learning or graphics projects, with tensor cores and 24 GB VRAM supporting model training and inference.

Student and office work: This pairing is massively overqualified for office tasks. The CPU's single-core GeekBench score of 1,899 is more than enough for word processing, spreadsheets, and web browsing, and the 10 cores handle multitasking. The GPU is not utilized in these workloads, and the 450 W TDP plus 850 W suggested PSU is wasted on such tasks. Students or office workers would be better served by a lower-tier GPU, but if this pairing is used for occasional 3D or video work, it performs excellently.

Benchmark Performance — exact CPU and GPU scores, percentile positions, and what the combined picture is

The CPU's benchmark results are consistent with a mid-range desktop processor. In Cinebench R15, it scores 1,716 multi-core and 242 single-core. In R20, it scores 7,152 multi-core and 1,009 single-core. In R23, it scores 17,029 multi-core and 2,404 single-core. GeekBench results are 10,227 multi-core and 1,899 single-core. The average benchmark score is 5,210, which places it at the 60th percentile among all CPUs. Its nearest rivals are the Intel Xeon E-2378G (0.2% higher), Intel Core i9-10850K (0.6% lower), Intel Core i7-11700B (0.6% lower), and Intel Core i5-14401E (0.8% lower). These deltas are all under 1%, meaning the i5-13400T performs within a rounding error of an older i9, which is a strong efficiency result given the 35 W TDP.

The GPU's benchmark results are exceptional. 3DMark Steel Nomad DX12 scores 9,223, GeekBench OpenCL scores 255,416, and GeekBench Vulkan scores 271,631. PassMark G3D scores 38,194, PassMark GPU compute scores 26,613, and the DirectX-specific PassMark tests range from 150 (DX12) to 397 (DX9). The average benchmark score is 60,347, placing it at the 88th percentile among all GPUs. Its nearest rivals are the Intel Arc Pro A60 (0% delta), AMD Radeon Pro Vega 48 (0.3% higher), AMD Radeon Pro W6600M (2.5% lower), and AMD Radeon PRO V710 (2.9% higher). These are professional cards, and the 4090's score is comparable to them in mixed workloads, though its gaming-specific hardware is far more capable.

The combined picture is one of imbalance. The CPU at the 60th percentile and GPU at the 88th percentile produce a combined percentile of 74, which is a weighted average that reflects the GPU's dominance in the overall score. In workloads that use the GPU heavily, this system will perform near the top of the desktop range. In CPU-bound workloads, it will perform like a mid-range system. The data does not include measured FPS for this pairing, so the precise gaming performance is unknown, but the benchmarking suggests that the GPU will be held back by the CPU in low-resolution gaming, while the CPU is sufficient for GPU-accelerated productivity.

FAQ — 5-7 Q&A pairs answerable from FACT PACK data

Q: What is the CPU's TDP and how does that affect system power requirements?

A: The Intel Core i5-13400T has a TDP of 35 W, which is very low for a 10-core processor. This means the CPU contributes minimally to system power draw, but the GPU's TDP is 450 W, and the suggested PSU for the RTX 4090 is 850 W. The CPU's efficiency does not reduce the overall PSU requirement because the GPU dominates power consumption.

Q: How much VRAM does the RTX 4090 have and what is its memory bandwidth?

A: The RTX 4090 has 24 GB of GDDR6X memory on a 384-bit bus, delivering a bandwidth of 1.01 TB/s. The memory clock is 1313 MHz with a 21 Gbps effective data rate. This large VRAM pool and high bandwidth support high-resolution textures and large compute workloads.

Q: Does the i5-13400T support overclocking?

A: No, the multiplier is not unlocked, so the CPU does not support overclocking. The boost clock of 4.40 GHz is the maximum frequency it can reach under load, and the base clock is 1300 MHz. Users are limited to the stock frequency behavior.

Q: What socket does the i5-13400T use and what memory types are supported?

A: The CPU uses Intel Socket 1700 and supports both DDR4 and DDR5 memory in a dual-channel configuration. It does not support ECC memory. The platform also has PCIe Gen 5 with 20 lanes from the CPU, though the GPU uses PCIe 4.0 x16.

Q: What is the RTX 4090's architecture and process node?

A: The RTX 4090 is based on the Ada Lovelace architecture using a 5 nm process at TSMC. The chip is AD102 with 76,300 million transistors on a 609 mm² die. It has 128 RT cores and 512 tensor cores for ray tracing and AI acceleration.

Q: How does the i5-13400T compare to the Intel Core i9-10850K?

A: In average benchmark scores, the i5-13400T is 0.6% behind the Intel Core i9-10850K. The i5-13400T has an average score of 5,210 compared to the i9-10850K's 5,240, and its 35 W TDP is dramatically lower than the i9's, making the i5 more efficient despite the slight performance deficit.

Q: Is the RTX 4090 still in production?

A: No, the production status is listed as end-of-life. Its release date was September 19, 2022, and its predecessor is the GeForce 30 series while its successor is the GeForce 50 series. This means it may be harder to find new in the future, though it remains a high-performance option.

Who Should Build It — target users and industries tied strictly to the measured performance

This pairing is for users who prioritize GPU-accelerated workloads over CPU-bound tasks. The RTX 4090's 88th percentile GPU rank, 24 GB VRAM, and 82.58 TFLOPS FP32 make it ideal for 3D artists and video editors who use GPU renderers—these users will see the full benefit of the 4090's compute power, and the CPU's 60th percentile rank is sufficient for scene management and non-GPU tasks. Gamers at 4K resolution will also benefit, because at that resolution the GPU becomes the bottleneck and the CPU's lower single-core score is less impactful; the 3DMark Steel Nomad score of 9,223 indicates strong DX12 gaming performance at high settings.

Content creators who stream will find the 4090's tensor cores and 24 GB VRAM useful for encoding and simultaneous capture, and the CPU's 10 cores and 16 threads handle streaming software alongside the game. Software developers working on machine learning or graphics applications can use the 4090's 512 tensor cores and 26,613 PassMark GPU compute score for local model training and inference, though the CPU's 10,227 GeekBench multi-core score will limit compilation speed. Students and office workers are not the target—this system is overkill for their workloads, and the 450 W GPU TDP plus 850 W suggested PSU is unnecessary for such tasks.

Small business workstations that run GPU-accelerated design, simulation, or data processing software would benefit from the 4090's raw compute, but the i5-13400T's 35 W TDP and 4.40 GHz boost clock mean that single-threaded business applications will not see flagship performance. The combined percentile of 74 indicates this is a mid-to-high-tier system overall, but the GPU is the clear driver of that ranking.

Build Overview — what this CPU+GPU pairing is, its class (desktop/laptop from buildClass), and overall tier from the percentiles

This is a desktop-class build, as indicated by the buildClass field. It pairs the Intel Core i5-13400T, a Raptor Lake 10-core processor with a 35 W TDP and 4.40 GHz boost clock, with the NVIDIA GeForce RTX 4090, an Ada Lovelace GPU with 16,384 shading units, 24 GB GDDR6X, and 82.58 TFLOPS FP32. The CPU is at the 60th percentile among all CPUs, and the GPU is at the 88th percentile among all GPUs, with a combined percentile of 74. This puts the system in the upper-mid tier of desktop configurations, but the wide gap between CPU and GPU performance means the overall tier is defined almost entirely by the GPU.

The CPU's average benchmark score of 5,210 is within 1% of older high-end CPUs like the Intel Core i9-10850K, which shows that the i5-13400T is an efficient performer despite its low TDP. The GPU's average benchmark score of 60,347 is comparable to professional workstation cards like the AMD Radeon Pro W6600M and Intel Arc Pro A60, but the 4090's gaming-specific hardware—RT cores, tensor cores, and high memory bandwidth—makes it more versatile. The launch MSRP for the CPU is $221, and the GPU has a launch MSRP of 1,599 USD, but those are historical values and not indicative of current pricing.

As a build, it is a GPU-first system. The RTX 4090 is a top-tier card, and the i5-13400T is a mid-range efficiency CPU. This is not a balanced gaming rig for high-refresh 1080p or 1440p, where the CPU will hold back the GPU, but it is a strong workstation for GPU-accelerated rendering and compute, and it is acceptable for 4K gaming where the GPU is the primary limiter.

Upgrade Path and Platform — socket, memory support, PCIe, PSU headroom from suggestedPsu/tdp, what a sensible next upgrade looks like

The platform is built around Intel Socket 1700, which supports the Core 13th Gen series. The i5-13400T supports both DDR4 and DDR5 memory in a dual-channel configuration, so the motherboard choice determines which memory type is used. The CPU has PCIe Gen 5 with 20 lanes from the CPU, but the RTX 4090 uses a PCIe 4.0 x16 bus interface, so the GPU is not limited by the PCIe version—PCIe 4.0 x16 provides sufficient bandwidth for the 4090. The CPU does not support ECC memory, which limits its use in some server or workstation scenarios.

The power requirement is driven by the GPU. The RTX 4090 has a TDP of 450 W, and the suggested PSU is 850 W. The CPU's TDP is 35 W, so the total system power draw is dominated by the GPU, and a quality 850 W PSU is recommended as the minimum. The GPU uses a 1x 16-pin power connector, so the PSU must have that connector or an adapter. The GPU is triple-slot in width, measuring 304 mm in length, 137 mm in height, and 61 mm in width, so the case must have sufficient clearance.

A sensible next upgrade would be to replace the CPU with a higher-tier Socket 1700 processor, such as an unlocked K-series part, to better match the GPU's performance. The i5-13400T is not multiplier-unlocked, so overclocking is not possible, and a CPU with a higher boost clock and more cores would reduce the bottleneck in CPU-bound workloads. The memory support for DDR5 means that moving to a DDR5 motherboard and high-speed DDR5 memory would also improve performance, particularly in memory-sensitive tasks. The GPU is already at the top of the GeForce 40 series, so the next upgrade for the GPU would be the GeForce 50 series, which is listed as its successor, but that would require a new GPU purchase and likely a PSU that can handle the new card's requirements. For most users, the first upgrade should be the CPU, as the RTX 4090 is already near the top of its class and the i5-13400T is the limiting factor in this pairing.
