# Pair Analysis: Intel Core Ultra 5 245K + NVIDIA GeForce RTX 4090 D

This desktop pairing combines Intel's 14-core Arrow Lake processor with NVIDIA's flagship Ada Lovelace GPU, landing in the 95th combined percentile against all CPU+GPU pairings in the database. The Core Ultra 5 245K holds a 91st percentile position among all CPUs, while the RTX 4090 D sits in the 98th percentile among all GPUs, making this a top-tier configuration by any measure. The data reveals an interesting asymmetry: the GPU is near the absolute top of the performance pyramid, while the CPU, though strong, sits slightly lower—a dynamic that shapes every workload profile examined below.

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

The RTX 4090 D is built on NVIDIA's Ada Lovelace architecture using a 5 nm TSMC process, housing 76,300 million transistors across a 609 mm² die. The chip, designated AD102, operates with a base clock of 2280 MHz and a boost clock of 2520 MHz, with memory running at an effective 21 Gbps. The 24 GB of GDDR6X memory is served by a 384-bit bus, producing a bandwidth of 1.01 TB/s—a figure that positions this card comfortably for high-resolution texture streaming and large dataset manipulation in professional rendering contexts.

The compute resources are substantial: 14,592 shading units, 456 texture mapping units, and 176 raster operation processors. Ray tracing hardware includes 114 RT cores, while 456 tensor cores handle AI-accelerated workloads. The pixel rate of 443.5 GPixel/s and texture rate of 1,149.1 GTexel/s indicate strong fill-rate capabilities for 4K and beyond. Floating-point performance reaches 73.54 TFLOPS for both FP32 and FP16 (at 1:1 ratio), which in the context of rendering means heavy shading workloads, real-time ray tracing, and DLSS-style AI upscaling all have ample headroom.

Benchmark results reinforce the card's top-tier status. In 3DMark Steel Nomad DX12, the card scores 8587, while Geekbench OpenCL and Vulkan scores reach 278621 and 246941, respectively. These scores place the GPU in the 98th percentile of all GPUs, with an average benchmark score of 178050. Comparing to nearest rivals, the RTX 4090 D trails the NVIDIA RTX PRO 5000 Blackwell by 2.2%, the A100 SXM4 80 GB by 3.1%, the RTX 5000 Ada Generation by 3.6%, and the A100 SXM4 40 GB by 4.9%. These deltas are small, indicating the 4090 D is within striking distance of workstation-class cards while offering the gaming-oriented feature set of the GeForce line.

The 24 GB VRAM capacity deserves particular attention. For 3D rendering, this allows entire scene datasets to reside on the GPU without spilling to system memory. The 1.01 TB/s bandwidth ensures that texture streaming and geometry processing at high resolutions remain fluid. The presence of 456 tensor cores means AI denoising and upscaling technologies have dedicated hardware, which can accelerate final-frame renders in supported applications.

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

The CPU's Cinebench results show a balanced profile: R15 multi-core scores 3850 with single-core at 322; R20 multi-core reaches 15368 with single-core at 2169; R23 multi-core hits 25066 with single-core at 2132. PassMark results further characterize the processor: multi-thread score of 43047, single-thread of 4714, with specialized workloads including data compression at 458817, data encryption at 33286, extended instructions at 37617, floating-point math at 130678, integer math at 98524, and physics at 3081. The average benchmark score for the CPU is 54053, placing it in the 91st percentile of all CPUs.

Against nearest CPU rivals, the Core Ultra 5 245K shows tight competition. It leads the Intel Xeon 6505P by 0.7% and the Intel Core i7-14700F by 0.8%, while trailing the AMD Ryzen 9 9900X3D by 1.3%. These single-digit percentage differences indicate that the 245K sits in a dense performance cluster where architectural differences matter more than raw score gaps.

The combined picture is one of GPU dominance. The RTX 4090 D's 98th percentile standing versus the CPU's 91st percentile means the GPU is the more exceptional component in this pairing. For workloads that scale with GPU compute—rendering, ray tracing, AI inference—the 4090 D will be the primary driver of performance. For CPU-bound tasks like physics simulation or data compression, the 245K holds its own but does not reach the same relative heights. The combined percentile of 95 reflects this balance: the whole system is elite, but the GPU carries more of the weight.

Gaming Performance — measured FPS by game and resolution from measuredFpsUltraByGame (or, if dataIsMeasured is false, frame expectations qualitatively from the benchmark scores and say the figures are estimates)

No measured FPS rows exist for this exact CPU+GPU combination in the database. The FACT PACK contains no measuredFps data for any game or resolution, so all frame rate discussion here is estimated from the benchmark scores and should be treated as directional rather than definitive.

The GPU's 3DMark Steel Nomad score of 8587 and its 98th percentile GPU rank suggest that at 1440p and 4K with ultra settings, this pairing should deliver high frame rates in most titles. The CPU's Cinebench R23 single-core score of 2132 and PassMark single-thread score of 4714 indicate strong per-core performance, which matters for games that are lightly threaded. The multi-core R23 score of 25066 ensures that heavily threaded game engines and background tasks will not starve the GPU.

Given the RTX 4090 D's position relative to rivals—trailing the RTX PRO 5000 Blackwell by only 2.2% and the A100 SXM4 80 GB by 3.1%—expectations for 4K ultra gaming are high. The 24 GB VRAM and 1.01 TB/s bandwidth are more than sufficient for current-generation textures at 4K. At 1440p, the CPU may become a more significant factor, as frame rates rise and per-frame CPU work dominates. At 1080p, the CPU's single-thread performance will likely be the limiting factor in esports titles, but the 245K's 91st percentile CPU rank suggests it will still deliver high refresh rates in most scenarios. These are estimates; actual figures depend on specific game engines and optimization levels.

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

The percentile gap between components—GPU at 98th, CPU at 91st—creates a predictable bottleneck profile. In GPU-bound scenarios like 4K gaming with ultra settings, the RTX 4090 D will be the limiting factor, but given its top-tier status, that limit is high. The GPU's small deltas to workstation rivals (2.2% to 4.9% behind) suggest that this card is near the practical ceiling for consumer GPU performance.

In CPU-bound workloads, the 245K becomes the constraint. The PassMark multi-thread score of 43047 and Cinebench R23 multi-core of 25066 are strong but not class-leading. For tasks like data compression (458817 in PassMark), the CPU's 14 cores and 14 threads handle parallel workloads well, but the lack of hyperthreading (14 cores, 14 threads) means each core must work harder. The single-thread PassMark score of 4714 indicates solid per-core performance, but the CPU's 0.7% to 0.8% leads over rivals like the Xeon 6505P and i7-14700F are narrow.

The FPS scaling picture—though based on estimates—suggests that at lower resolutions where frame rates rise, the CPU's single-thread performance (R23 single-core 2132) will increasingly become the bottleneck. At higher resolutions, the GPU's fill rate and memory bandwidth dominate. For mixed workloads like game streaming while recording, the CPU's multi-thread score of 43047 provides headroom for encoding tasks alongside gaming, but the 14-thread limit means there is less spare capacity than a 20-thread processor might offer.

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

The CPU uses the Intel Socket 1851 platform with Arrow Lake architecture, supporting DDR5 memory in dual-channel configuration. The memory bandwidth of 102.4 GB/s is a current-generation figure, and ECC support makes this platform suitable for workstation-adjacent tasks. The CPU provides PCIe Gen 5 with 20 lanes, while the GPU interfaces via PCIe 4.0 x16—a match that does not bottleneck the RTX 4090 D given the card's bandwidth requirements.

The CPU's TDP is 125 W, while the GPU's TDP is 425 W. The suggested power supply for the GPU alone is 800 W, which provides sufficient headroom for the entire system assuming a quality PSU. The GPU requires a single 16-pin power connector and occupies a triple-slot width, measuring 304 mm in length, 137 mm in height, and 61 mm in width. Case compatibility requires attention to length and slot clearance.

A sensible next upgrade path depends on workload. For gaming, the GPU is near the top of the stack, so upgrading the CPU to a higher-core-count Arrow Lake part would address the 91st versus 98th percentile gap. For rendering professionals, the 24 GB VRAM is substantial, but if workloads exceed this, moving to a workstation card like the RTX PRO 5000 Blackwell (which leads the 4090 D by 2.2%) would be a marginal performance gain. The platform itself—Socket 1851 with DDR5 and PCIe Gen 5—has room for future CPU upgrades within the same generation.

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

The Intel Core Ultra 5 245K is a 14-core, 14-thread processor from the Core Ultra Series 2, built on Arrow Lake-S architecture with a 3 nm TSMC process. The die contains 17,800 million transistors across 243 mm². Base clock is 4.20 GHz with a boost clock of 5.20 GHz, and the multiplier is unlocked for overclocking. The cache hierarchy consists of 192 KB L1 per core, 3 MB L2 per core, and 24 MB of shared L3 cache.

The 14 cores with 14 threads (no hyperthreading) means the CPU relies on physical cores for parallelism. This design choice favors workloads with predictable thread counts over those that benefit from logical thread oversubscription. The PassMark multi-thread score of 43047 and Cinebench R23 multi-core of 25066 indicate strong all-core performance, while the single-thread scores (PassMark 4714, R23 single-core 2132) show competitive per-core capability.

Real-world implications: data compression scores of 458817 in PassMark suggest excellent archival and file-handling performance. Encryption at 33286 indicates solid security-related throughput. Floating-point math at 130678 and integer math at 98524 point to strong general compute. The physics score of 3081, while lower in absolute terms, is typical for a CPU of this class and supports gaming physics simulation. The integrated Arc Xe-LPG Graphics with 64EU provides a fallback display output and basic acceleration, though the discrete RTX 4090 D renders it largely irrelevant for graphics work.

The CPU's 91st percentile rank and narrow deltas to rivals (0.7% ahead of Xeon 6505P, 0.8% ahead of i7-14700F, 1.3% behind Ryzen 9 9900X3D) place it in a competitive sweet spot. For content creation, the multi-thread scores translate to faster video exports and 3D scene compilation. For software development, the single-thread performance accelerates compilation of serial code sections, while the multi-thread capability handles parallel builds.
