# Performance Analysis: Intel Core i5-12400T + NVIDIA GeForce RTX 5090 D V2

This desktop pairing combines a 6-core, 12-thread Intel Alder Lake processor with a flagship-class NVIDIA Blackwell GPU, creating a configuration where the CPU sits at the 57th percentile among all processors and the GPU at the 59th percentile among all GPUs. The combined build percentile is 58, indicating a mid-to-upper tier desktop system whose gaming potential is almost entirely dictated by the graphics card, while the processor handles general productivity with moderate competence. No measured FPS data exists for this exact CPU+GPU combination, so all frame-rate discussion in this analysis is estimated from the benchmark scores and percentile positions rather than derived from direct testing.

Gaming Performance

The FACT PACK contains no measured FPS rows for this exact combination, meaning there are no tested frame rates at any resolution or quality preset to cite. All gaming expectations must therefore be inferred from the GPU's 3DMark Steel Nomad DX12 score of 16,504 and the CPU's Cinebench and Geekbench results. The RTX 5090 D V2's 3DMark score places it at the 59th percentile among all GPUs, with its nearest rival being the NVIDIA T400 at 16,508 (a deltaPct of 0), followed by the AMD Radeon PRO W7500 at 16,415 (0.5% behind), the NVIDIA RTX PRO 6000 Blackwell at 16,408 (0.6% behind), and the AMD Radeon RX 5700 XT at 16,361 (0.9% behind). This score cluster suggests the GPU delivers performance essentially on par with those workstation and previous-generation gaming cards in this specific DirectX 12 workload, though the RTX 5090 D V2 brings 24 GB of GDDR7 memory and a 1.34 TB/s memory bandwidth that those rivals do not match.

For 1080p gaming, the CPU's single-core performance becomes the primary constraint. The i5-12400T scores 1,868 in Cinebench R23 single-core and 2,044 in Geekbench single-core, which are respectable but not exceptional figures for a 12th-generation part with a 4.20 GHz boost clock. At this resolution, frame rates are likely to be limited by the processor in CPU-bound titles, especially in scenes with many on-screen entities or complex physics. The GPU's raw compute power, including 104.8 TFLOPS of FP32 performance and 21,760 shading units, would be underutilized at 1080p in many scenarios, as the 6-core CPU becomes the bottleneck before the graphics card can stretch its legs.

At 1440p, the balance shifts toward the GPU. The graphics card's 176 ROPs and 1,636.8 GTexel/s texture rate provide ample fill-rate headroom, and the 24 GB memory capacity ensures that even the most demanding textures fit comfortably within VRAM. Estimated frame rates at this resolution would be substantially higher than 1080p CPU-limited scenarios, though the CPU may still cause occasional dips in poorly optimized titles. The 59th GPU percentile suggests the card performs in line with its nearest rivals, which include both professional workstation cards and the older Radeon RX 5700 XT, a card that was mid-range in its day — indicating the RTX 5090 D V2's actual gaming throughput may be less spectacular than its flagship branding suggests.

At 4K, the GPU becomes the dominant factor, and the CPU's limitations are largely masked by the increased pixel workload. The 423.6 GPixel/s pixel rate and 1.34 TB/s bandwidth position the card to handle 4K resolution with high detail settings in most titles, though the lack of measured data means these are estimates grounded in the benchmark scores rather than verified results. The CPU's Cinebench R23 multi-core score of 13,234 is sufficient to feed the GPU at 4K in most games, where per-frame CPU work is a smaller fraction of total frame time.

Usage Scenarios

High-refresh gaming: The combination of a 57th-percentile CPU and 59th-percentile GPU does not clearly target high-refresh 1080p or 1440p gaming. The CPU's Geekbench single-core score of 2,044 and Cinebench R23 single-core score of 1,868 are mid-pack figures, suggesting the processor may struggle to sustain 144 Hz or higher frame rates in CPU-intensive competitive titles. At 1440p, the GPU's 3DMark Steel Nomad score of 16,504 indicates adequate throughput for high-refresh 1440p in less demanding games, but the pairing is better suited to 60-100 Hz gaming than extreme refresh rates.

Streaming: The i5-12400T's 6 cores and 12 threads provide a reasonable baseline for streaming while gaming, but the Cinebench R23 multi-core score of 13,234 is not exceptionally high for simultaneous encode and game workloads. The GPU does not have a dedicated encoder mentioned in the FACT PACK, so streaming performance relies on the CPU's general compute capabilities, which are adequate for 1080p streaming but may strain under heavy multitasking.

Video editing: The CPU's Geekbench multi-core score of 7,144 and Cinebench R20 multi-core score of 5,558 indicate moderate capability for video editing workloads. The GPU's 24 GB VRAM and 104.8 TFLOPS FP32 performance could accelerate rendering and effects, but the overall editing experience would be limited by the CPU's mid-tier position at the 57th percentile among all CPUs. Timeline scrubbing and codec-heavy tasks would benefit from the GPU, while export times would reflect the CPU's 6-core architecture.

3D rendering: The GPU's 104.8 TFLOPS FP32 and 170 RT cores provide substantial raw compute for GPU-accelerated rendering, potentially outperforming the CPU in most render workloads. The CPU's Cinebench R23 multi-core score of 13,234 places it in the lower half of the 57th percentile range, meaning CPU-based rendering would be slow relative to high-end processors. For GPU-accelerated renderers like those using CUDA, the RTX 5090 D V2 would be the clear workhorse.

Software development: The 6-core, 12-thread configuration with 18 MB of shared L3 cache handles compilation and multitasking reasonably well, though the 57th CPU percentile indicates it is not a top-tier developer machine. The 1,868 Cinebench R23 single-core score affects code editor responsiveness, while the 13,234 multi-core score supports parallel builds with moderate efficiency. The memory support for DDR4 and DDR5 allows flexible system configuration, though no memory bandwidth figures are available to assess throughput.

Student and office work: For everyday productivity, this pairing is massively overprovisioned on the GPU side and adequately provisioned on the CPU side. The integrated UHD Graphics 730 provides a fallback display output, and the 35W CPU TDP suggests efficient operation for light workloads. Office applications, web browsing, and document editing would run smoothly, with the GPU largely idle and the CPU's single-core score of 2,044 in Geekbench handling interactive tasks without issue.

Benchmark Performance

The CPU's average benchmark score is 4,019, placing it at the 57th percentile among all CPUs. Its nearest rival is the AMD Ryzen 5 PRO 4655G with an average score of 4,010, a deltaPct of 0.2% — effectively a statistical tie. The Intel Xeon E5-2698B v3 scores 4,004 (0.4% ahead of the i5-12400T), while the Intel Xeon E-2278G scores 4,052 (0.8% behind the i5-12400T), and the Intel Xeon E-2336 scores 3,985 (0.9% ahead). This tight cluster shows the i5-12400T sits squarely in a group of older and workstation-class processors, neither clearly beating nor losing to any of them. The individual benchmark scores include Cinebench R15 multi-core at 1,333 and single-core at 188, Cinebench R20 multi-core at 5,558 and single-core at 784, Cinebench R23 multi-core at 13,234 and single-core at 1,868, and Geekbench multi-core at 7,144 and single-core at 2,044.

The GPU's benchmark results consist of a single 3DMark Steel Nomad DX12 score of 16,504, placing it at the 59th percentile among all GPUs. Its nearest rival is the NVIDIA T400 with a score of 16,508 and a deltaPct of 0, meaning the two cards perform identically in this test. The AMD Radeon PRO W7500 scores 16,415 (0.5% behind), the NVIDIA RTX PRO 6000 Blackwell scores 16,408 (0.6% behind), and the AMD Radeon RX 5700 XT scores 16,361 (0.9% behind). The combined picture is a system where both components sit near the 57-59th percentile range, indicating a balanced-if-modest overall tier despite the GPU's flagship-class specifications and 92,200 million transistors.

Balance and Bottleneck

The data reveals a system where the CPU and GPU occupy nearly identical percentile positions — 57th for the CPU and 59th for the GPU — which suggests a rough balance in overall performance tier. However, the workload-dependent nature of bottlenecks becomes clear when examining specific scores. The CPU's Cinebench R23 multi-core score of 13,234 and Geekbench multi-core score of 7,144 are mid-range figures that would limit frame rates in CPU-bound scenarios, particularly at 1080p resolution where the GPU's 16,504 3DMark score has more headroom than the processor can feed. The GPU's 104.8 TFLOPS FP32 compute vastly exceeds what the CPU's 6 cores can generate in terms of draw calls and game logic, creating a scenario where the processor is the limiting factor in most gaming workloads.

Conversely, in GPU-bound scenarios such as 4K gaming or heavy graphics rendering, the GPU becomes the constraint, and the CPU's 35W TDP and 4.20 GHz boost clock are sufficient to keep up. The FPS scaling between resolutions would show a characteristic pattern: at 1080p, the CPU bottleneck would cap frame rates; at 1440p, the balance improves; and at 4K, the GPU's workload dominates, and the system behaves as a GPU-limited configuration. The lack of measured FPS data prevents quantifying this scaling, but the percentile positions and benchmark scores support this interpretation. For non-gaming workloads like video editing or 3D rendering, the GPU's 24 GB VRAM and 170 RT cores would accelerate GPU-compute tasks, while the CPU's 12 threads handle the serial portions of those workloads — a division where neither component fully bottlenecks the other.

CPU Analysis

The Intel Core i5-12400T is a 6-core, 12-thread processor based on the Alder Lake architecture, manufactured on Intel's 10 nm process node with a die size of 163 mm². It operates with a base clock of 1,800 MHz and a boost clock of 4.20 GHz, with a 35W TDP that emphasizes power efficiency over raw performance. The cache hierarchy consists of 80 KB of L1 per core, 1.25 MB of L2 per core, and 18 MB of shared L3 cache. The processor supports DDR4 and DDR5 memory in a dual-channel configuration, with no ECC support, and provides PCIe Gen 5 with 20 lanes from the CPU. Integrated graphics come in the form of UHD Graphics 730, and the CPU is not multiplier-unlocked.

The benchmark scores reflect a processor that is competent but not exceptional for its generation. The Cinebench R23 multi-core score of 13,234 places it at the 57th percentile, meaning 57% of all CPUs perform below this level — a solid mid-tier result. The single-core score of 1,868 in Cinebench R23 is more modest, indicating that lightly threaded tasks like gaming or office applications will see average performance. The Geekbench scores of 7,144 multi-core and 2,044 single-core corroborate this picture. The nearest rivals — the AMD Ryzen 5 PRO 4655G, Intel Xeon E5-2698B v3, Intel Xeon E-2278G, and Intel Xeon E-2336 — all fall within a 0.9% deltaPct of the i5-12400T's average score, showing that this CPU performs essentially on par with a range of older workstation and APU parts. For real workloads, this means the i5-12400T handles everyday multitasking, moderate productivity, and light content creation without struggle, but it will not excel in heavily threaded workloads like 3D rendering or video encoding, where its 6 cores and 18 MB L3 cache are limiting factors.

Who Should Build It

The target user for this pairing is a desktop builder who prioritizes GPU compute capability and gaming at higher resolutions over CPU-intensive tasks. At 1080p, the system is CPU-limited, so gamers playing at this resolution would not fully utilize the RTX 5090 D V2's capabilities — the 3DMark score of 16,504 and 104.8 TFLOPS FP32 are wasted in scenarios where the CPU cannot keep pace. Gamers at 1440p or 4K would see better utilization, as the GPU's 24 GB VRAM and 1.34 TB/s bandwidth handle high-resolution textures and pixel workloads effectively. Content creators working with GPU-accelerated renderers or effects would benefit from the 170 RT cores and 21,760 shading units, though the CPU would bottleneck CPU-bound portions of their pipelines.

Software developers would find the 6-core, 12-thread configuration workable for compilation and testing, with the 57th CPU percentile indicating adequate but not premium performance. Students and office workers would be massively overserved by this GPU, but the CPU's 35W TDP makes the system efficient for daily use. Small business workstations running GPU-accelerated applications like CAD or data visualization would benefit from the 24 GB memory and 104.8 TFLOPS compute, provided their software leverages CUDA or similar GPU compute. The build is not ideal for budget-conscious builders, as the GPU's launch MSRP is 2,299 USD, but the CPU's launch MSRP is $192 — a pairing that allocates most of the budget to graphics.

Upgrade Path and Platform

The system is built on the Intel Socket 1700 platform, which supports the i5-12400T's Alder Lake architecture. The motherboard must accommodate DDR4 or DDR5 memory, with dual-channel support; the choice between memory types affects system performance, though the FACT PACK does not provide bandwidth figures to quantify the difference. The CPU provides PCIe Gen 5 with 20 lanes, and the GPU uses a PCIe 5.0 x16 interface, ensuring full bandwidth compatibility. The GPU's suggested PSU is 950 W, while the CPU's TDP is 35W, leaving substantial power headroom for future upgrades — the 575W GPU TDP is the dominant power draw, and a 950W PSU can handle additional components or a more power-hungry CPU.

A sensible next upgrade would be to replace the i5-12400T with a higher-core-count Socket 1700 processor, as the platform supports the full 12th-generation lineup — though the FACT PACK does not specify which specific CPUs are compatible beyond the socket. The 35W TDP of the current CPU means the cooling and power delivery are likely underutilized, so a higher-TDP processor would fit within the existing PSU headroom. Alternatively, adding more memory or upgrading from DDR4 to DDR5 (if the motherboard supports both) would improve memory-bound workloads. The GPU's 24 GB VRAM is already substantial, so a GPU upgrade would not be necessary for several generations; the more pressing upgrade path is CPU-side, to remove the bottleneck at 1080p and better feed the GPU at higher resolutions.

Build Overview

This is a desktop-class build combining the Intel Core i5-12400T, a 6-core/12-thread Alder Lake processor with a 35W TDP and integrated UHD Graphics 730, with the NVIDIA GeForce RTX 5090 D V2, a Blackwell 2.0 architecture GPU featuring 24 GB of GDDR7 memory, 21,760 shading units, and 104.8 TFLOPS FP32 compute. The combined percentile is 58, placing the system in the upper-mid tier of desktop configurations. The CPU sits at the 57th percentile among all CPUs, and the GPU at the 59th percentile among all GPUs, indicating that both components are near the median of their respective categories — despite the GPU's flagship-tier specifications, its benchmark performance is on par with cards like the NVIDIA T400 and AMD Radeon RX 5700 XT in the 3DMark Steel Nomad test. The overall tier is thus solidly mid-range, with the GPU providing the majority of the system's compute capability and the CPU serving as a competent but unremarkable partner.
