Doom

The AMD Ryzen 5 5600X and NVIDIA GeForce RTX 5070 combination delivers a robust experience in Doom, with performance metrics that clearly delineate the strengths and limits of each component. This analysis examines the measured data to understand how the CPU and GPU contribute to the final framerates across various settings and resolutions.

CPU Role — cores, clocks, and how they relate to this game's results

The AMD Ryzen 5 5600X is a 6-core, 12-thread processor based on the Zen 3 architecture, codenamed Vermeer, manufactured on a 7 nm process by TSMC. It operates with a base clock of 3.70 GHz and a boost clock of 4.60 GHz, with a 65W TDP. Its cache hierarchy includes 64 KB of L1 and 512 KB of L2 per core, plus a 32 MB L3 cache. The processor supports DDR4 memory in a dual-channel configuration, offering a memory bandwidth of 51.2 GB/s.

In synthetic benchmarks, the 5600X shows a strong single-threaded capability, scoring 917 in 3dmark_single_thread and 2622 in cinebench_r23_singlecore. Its multi-threaded performance is represented by a cinebench_r23_multicore score of 18578 and a 3dmark_max_threads score of 5588. The processor achieves an average benchmark score of 20680, placing it in the 78th percentile of all CPUs. Compared to its nearest rivals, the 5600X trails the AMD Ryzen 5 5600GT by a negligible 0.3% and the Intel Core i7-10700 by the same margin, while it leads the Intel Xeon 6325P by 0.7%. This data suggests a balanced processor that should not bottleneck a high-end GPU in most gaming scenarios.

For Doom, a title from 2016, the CPU’s role is primarily to feed the GPU with draw calls and manage game logic. The strong single-thread score of 2622 in cinebench_r23 suggests that the CPU can handle the primary game thread efficiently. The high average FPS at lower resolutions, such as 336.6 FPS at 1080p Low, indicates that the CPU is capable of driving the frame rate to very high levels. However, at lower resolutions, the game becomes progressively more CPU-bound, meaning the 5600X’s limits start to show as the GPU is not fully taxed. The data shows a clear ceiling as resolution decreases, with the 1080p results being significantly higher than 4K, but the relative scaling between settings remains consistent, pointing to a capable CPU that works well in tandem with the GPU.

GPU Role — VRAM, clocks, and how they relate to this game's results

The NVIDIA GeForce RTX 5070 is built on the Blackwell 2.0 architecture, using the GB205 chip on a 5 nm process. It features 6144 shading units, 192 texture mapping units, and 80 render output units. The GPU has a base clock of 2325 MHz and a boost clock of 2512 MHz. Its memory subsystem is substantial, with 12 GB of GDDR7 memory on a 192-bit bus, providing a bandwidth of 672.0 GB/s. The memory clock runs at 1750 MHz, or 28 Gbps effective. The GPU’s raw compute capabilities are highlighted by a FP32 performance of 30.87 TFLOPS and a pixel rate of 201.0 GPixel/s.

In benchmarks, the RTX 5070 scores 5077 in 3dmark_steel_nomad_dx12 and 29137 in passmark_g3d. Its average benchmark score is 41687, which places it in the 83rd percentile of all GPUs. When compared to its nearest rivals, the RTX 5070 is essentially tied with the AMD Radeon Pro 5300, which has a 0.2% higher score, and the NVIDIA Tesla M40, which is 0.5% lower. It also sits close to the NVIDIA GeForce RTX 3090, which is 0.6% lower.

The GPU’s performance in Doom is the primary driver of the results at higher resolutions. With 12 GB of VRAM, the card has ample memory for the game’s textures at any setting. The data shows a consistent decrease in FPS as settings are increased from Low to Ultra at each resolution, which is expected. At 4K, the GPU is clearly the limiting factor. The framerate drops significantly from 120.1 FPS at Low to 72.3 FPS at Ultra, indicating that the GPU's rendering load is the bottleneck. The substantial bandwidth of 672.0 GB/s helps maintain high performance even at 4K Ultra, but the compute demands of the higher settings ultimately cap the FPS.

How This Combo Ranks

The AMD Ryzen 5 5600X and NVIDIA GeForce RTX 5070 combination ranks 323rd out of 1681 tested combos in this game. This places the pairing in the top 20% of all configurations tested. This ranking is a strong indicator that the combination is well-balanced for gaming. The CPU’s 78th percentile performance and the GPU’s 83rd percentile performance align to create a system that is likely to avoid severe bottlenecks in either direction. The high rank suggests that this pairing is more capable than the vast majority of tested systems, which often feature older or more mismatched components. The data points to a system that is well-suited for high-refresh-rate gaming at 1440p and capable of handling 4K with adjustments to settings.

Resolution Scaling

The measured FPS data shows a clear scaling pattern across resolutions. At 1080p, the system achieves very high framerates, with an average of 336.6 FPS on Low settings and 252.6 FPS on High. Moving to 1440p, these numbers drop to 222 FPS on Low and 161.3 FPS on High. At 4K, the performance falls further to 120.1 FPS on Low and 87.1 FPS on High. This pattern indicates that the system is heavily GPU-bound at 4K, as the load on the GPU increases exponentially with pixel count.

The scaling from 1080p to 4K shows the limiting component. At 1080p, where the GPU has an easier time, the CPU becomes more of a factor, but the framerates are so high that it is not a practical concern. The drop from 1080p High (252.6 FPS) to 1440p High (161.3 FPS) is a 36% reduction, while the drop from 1440p High to 4K High (87.1 FPS) is a 46% reduction. This larger percentage drop at higher resolutions confirms that the GPU is the primary bottleneck as resolution increases. The game remains very playable at 4K, but the data suggests that for maximum performance, 1440p is the sweet spot for this combination.

Measured FPS Breakdown

The following data provides a detailed look at the average FPS for each tested setting and resolution combination.

At 1920x1080, the performance is exceptionally high. With Low settings, the average FPS is 336.6. Increasing to Medium settings yields 298.2 FPS. High settings produce 252.6 FPS, and Ultra settings result in 206.1 FPS. The difference between Low and Ultra at this resolution is 130.5 FPS, showing that even at the highest settings, the system can easily push past 200 FPS.

At 2560x1440, the framerates remain very high. Low settings deliver an average of 222 FPS. Medium settings follow with 193.1 FPS, and High settings with 161.3 FPS. Ultra settings bring the average down to 131.1 FPS. The scaling from Low to Ultra at 1440p is a drop of 90.9 FPS, which is a significant but expected reduction.

At 3840x2160, the GPU is working hardest. Low settings produce an average of 120.1 FPS, which is still a great experience. Medium settings yield 101.3 FPS, while High settings result in 87.1 FPS. Ultra settings are the most demanding, with an average of 72.3 FPS. The gap between Low and Ultra at 4K is 47.8 FPS. This data shows that the system is capable of maintaining above 60 FPS at 4K Ultra, but for the smoothest experience, lowering settings to High or Medium is recommended.
