# GPU Role

The NVIDIA GeForce RTX 5090 D is built on the Blackwell 2.0 architecture using the GB202 chip on a 5 nm process. It carries 32 GB of GDDR7 memory on a 512-bit bus, delivering a memory bandwidth of 1.79 TB/s. The GPU clock speeds are a base of 2017 MHz and a boost of 2407 MHz, with memory running at 1750 MHz (28 Gbps effective).

In Doom, the GPU's role is decisive at higher resolutions. The measured FPS data shows that at 4K Ultra settings, the average FPS is 102, while at 4K Low settings it rises to 170. This 68 FPS gap between settings at the same resolution highlights how much the GPU's shading hardware handles the increased visual load. The RTX 5090 D has 21,760 shading units, 680 TMUs, and 176 ROPs, with a pixel rate of 423.6 GPixel/s and a texture rate of 1,636.8 GTexel/s.

The memory subsystem is particularly relevant for a game like Doom, which benefits from high bandwidth. The 1.79 TB/s bandwidth ensures that texture streaming and frame buffer operations are not constrained at any tested setting. The 32 GB capacity is far beyond what Doom requires, but the bus width and speed contribute to the sustained high FPS observed at 1440p and 1080p. The GPU's FP32 throughput of 104.8 TFLOPS provides ample compute headroom for the game's rendering workloads, which is reflected in the 285 FPS average at 1080p Ultra.

The GPU's percentile ranking among all GPUs is 92, meaning it outperforms 92% of tested graphics cards. Its average benchmark score of 77,712 is close to the AMD Radeon RX 6850M XT, which scores 78,940, a difference of 1.6%. This proximity in synthetic benchmarks does not fully translate to Doom-specific performance, as the measured FPS shows the RTX 5090 D delivering extremely high frame rates even at 4K.

# How This Combo Ranks

The combo of the AMD Ryzen 5 5600 and NVIDIA GeForce RTX 5090 D ranks 101st out of 2,930 tested combinations in Doom. This puts it in the top 3.4% of all combos tested, which is remarkable given the CPU is a mid-range 2022 processor paired with a top-tier 2025 GPU.

The ranking suggests that Doom is not heavily CPU-bound at most settings, allowing the RTX 5090 D to stretch its legs. The CPU's 74th percentile ranking among all CPUs (average benchmark score of 20,468) is far lower than the GPU's 92nd percentile, yet the combo still lands in the top 101. This indicates that the game's engine leverages the GPU more than the CPU, and the Ryzen 5 5600's six cores and twelve threads are sufficient to keep the GPU fed.

Comparing to other combos, the rank of 101 out of 2,930 means there are 100 combos that perform better. These likely include pairings with higher-end CPUs such as the Ryzen 7 or Ryzen 9 series, but the delta in Doom's FPS is likely small. The data shows that at 1080p Ultra, the combo achieves 285 FPS average, which is already far beyond what most displays can show. The ranking is therefore more of a theoretical ceiling than a practical limitation for most users.

The nearest CPU rivals in average benchmark score — the Intel Core Ultra 7 258V, AMD Ryzen 5 8500G, and AMD EPYC 9454P — all score within 0.5% of the Ryzen 5 5600. This near-parity in CPU performance suggests that swapping to any of these would not meaningfully change the combo's rank in Doom. The GPU is the primary driver of the high rank.

# Measured FPS Breakdown

At 1920x1080, the combo delivers its highest frame rates. With Low settings, the average FPS is 341. Medium settings reduce this to 325 FPS, with a minimum of 276 and a maximum of 374. High settings yield 306 FPS average, and Ultra settings produce 285 FPS average. The spread from Low to Ultra is 56 FPS, or 16.4%, showing that even at maximum settings the game remains highly playable.

At 2560x1440, the performance remains strong but drops noticeably. Low settings average 295 FPS, Medium averages 273 FPS with a minimum of 232 and a maximum of 314, High averages 231 FPS, and Ultra averages 189 FPS. The drop from 1080p to 1440p at Ultra settings is from 285 to 189 FPS, a reduction of 33.7%. This indicates that the GPU is being pushed harder at the higher pixel count, but the frame rates are still well above typical high-refresh-rate display capabilities.

At 3840x2160, the performance falls further but remains playable across all settings. Low settings average 170 FPS, Medium averages 148 FPS with a minimum of 126 and a maximum of 170, High averages 125 FPS, and Ultra averages 102 FPS. The gap between Low and Ultra at 4K is 68 FPS, which is the largest absolute difference across all resolutions. This suggests that at 4K, the GPU's shading units and memory bandwidth are the primary determinants of performance, and the visual complexity of Ultra settings imposes a significant cost.

The minimum FPS data is only available for Medium settings at each resolution: 276 at 1080p, 232 at 1440p, and 126 at 4K. These minimums are all above 120 FPS, which is notable because it indicates that even in demanding scenes, the frame rate does not drop below a high threshold. The maximum FPS values follow a similar pattern, with 374 at 1080p, 314 at 1440p, and 170 at 4K.

# Resolution Scaling

The FPS scaling from 1080p to 4K reveals important information about the limiting component in this combo. At High settings, the average FPS drops from 306 at 1080p, to 231 at 1440p, to 125 at 4K. The percentage drop from 1080p to 1440p is 24.5%, while the drop from 1440p to 4K is 45.9%. This steepening decline indicates that the GPU is becoming increasingly saturated as resolution increases.

At Ultra settings, the scaling is similar: 285 FPS at 1080p, 189 FPS at 1440p, and 102 FPS at 4K. The drops are 33.7% and 46.0%, respectively. The near-identical percentage drop from 1440p to 4K across High and Ultra settings (45.9% vs 46.0%) suggests that the GPU's rendering pipeline is the bottleneck at these resolutions, regardless of the visual quality preset.

At Low settings, the scaling is shallower: 341 FPS at 1080p, 295 FPS at 1440p, and 170 FPS at 4K. The drop from 1080p to 1440p is 13.5%, and from 1440p to 4K is 42.4%. The smaller drop at 1440p Low indicates that the CPU can keep up with the GPU's output at lower settings, but at 4K, the GPU's pixel throughput becomes the limiting factor.

The data suggests that at 1080p, the CPU plays a more significant role in limiting FPS. The Ryzen 5 5600's six cores and twelve threads have a base clock of 3.50 GHz and a boost of 4.40 GHz, which is sufficient for high frame rates but cannot fully exploit the RTX 5090 D's potential at lower resolutions. At 4K, the GPU's 423.6 GPixel/s pixel rate and 1.79 TB/s bandwidth become the dominant constraints, as evidenced by the consistent 42-46% drop from 1440p to 4K across all settings.

# CPU Role

The AMD Ryzen 5 5600 is a 6-core, 12-thread processor based on the Zen 3 architecture, codenamed Vermeer. It has a base clock of 3.50 GHz and a boost clock of 4.40 GHz, with a TDP of 65 W. The CPU's cache configuration includes 64 KB of L1 cache per core, 512 KB of L2 cache per core, and 32 MB of shared L3 cache.

In Doom, the CPU's role is most visible at 1080p, where frame rates exceed 300 FPS. At these high frame rates, the CPU must process game logic, physics, and draw calls quickly enough to feed the GPU. The Ryzen 5 5600's single-thread performance, as measured by a Cinebench R23 single-core score of 2,584, is sufficient to achieve 341 FPS at 1080p Low and 285 FPS at 1080p Ultra. However, the fact that the FPS drops from 341 to 285 when moving from Low to Ultra at the same resolution suggests that the GPU is doing more work, but the CPU is still keeping pace.

The multi-threaded performance of the CPU, with a Cinebench R23 multi-core score of 18,309 and a Passmark multithread score of 21,541, provides solid headroom for Doom's multi-threaded rendering tasks. The game's Vulkan API can utilize multiple threads, and the 12 threads of the Ryzen 5 5600 are adequate for this workload. The 3DMark 16-thread score of 5,641 and 8-thread score of 4,798 show that scaling is not perfectly linear, but the CPU does not appear to bottleneck the GPU in Doom.

The CPU's memory bandwidth of 51.2 GB/s (dual-channel DDR4) is modest compared to the GPU's 1.79 TB/s, but this does not hinder performance in Doom. The game's data transfer requirements are well within the CPU's capabilities. The CPU's percentile ranking of 74 places it below the GPU's 92nd percentile, yet the combo still achieves a top-101 rank. This suggests that Doom's engine is GPU-heavy, and the Ryzen 5 5600 provides sufficient support without becoming a significant limiting factor, except perhaps at the very highest frame rates at 1080p where the 341 FPS ceiling may be partially CPU-constrained.
