Doom

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

The AMD Ryzen 5 7600 brings a 6-core, 12-thread configuration based on Zen 4 architecture, with a base clock of 3.80 GHz and a boost clock of 5.10 GHz. This desktop processor, built on TSMC's 5 nm process, also carries 32 MB of shared L3 cache, which is often a relevant factor in game performance. In Doom, a fast-paced FPS originally released in 2016, the CPU's role can be inferred from the measured frame rates across resolutions.

At 1080p, the data shows very high average FPS values: 248.8 on High, 294.5 on Medium, 336 on Low, and 203.6 on Ultra. These numbers suggest the Ryzen 5 7600 is not a bottleneck at this resolution, as the frame rates scale significantly with settings changes. The single-thread performance of this CPU, reflected in its 3DMark single-thread score of 999 and Cinebench R23 single-core score of 3246, likely supports the game's main thread effectively. Meanwhile, the multi-threaded capabilities, seen in the Cinebench R23 multi-core score of 22992, may help with background tasks or any additional threads Doom leverages.

Interestingly, the CPU's benchmark profile places it in the 83rd percentile vs all CPUs, with an average benchmark score of 26617. Its nearest rivals include the AMD Ryzen 7 5800X3D (deltaPct 0.2), Intel Core i9-12900HK (deltaPct -0.2), AMD EPYC 8024P (deltaPct 0.2), and Intel Core i9-11900K (deltaPct 0.3). These deltas are extremely small, meaning the Ryzen 5 7600's overall compute performance is nearly identical to those chips, despite differences in core counts and architectures. For Doom specifically, this parity suggests that the CPU is not a distinguishing factor when paired with a high-end GPU; rather, the GPU and settings dictate the outcome.

The L3 cache size of 32 MB is worth noting. Doom's engine, id Tech 6, is known for being well-optimized and not heavily cache-dependent, but the data here implies that the CPU's 6 cores are sufficient to feed the Radeon RX 7900 XT at all tested settings. At 4K, the frame rates drop (e.g., 84.3 on High), but this is more attributable to GPU load than CPU limits, as the same CPU at 1080p pushes well over 200 FPS on most presets.

Resolution Scaling — how FPS drops from 1080p to 4K and what it says about the limiting component

The measured FPS data reveals a clear pattern of performance degradation as resolution increases, which is typical when the GPU becomes the primary limiting factor. Starting at 1920x1080, the combo achieves 248.8 FPS on High, 294.5 on Medium, 336 on Low, and 203.6 on Ultra. Moving to 2560x1440, these figures drop to 158.8, 188.8, 217.8, and 134.2 respectively. At 3840x2160, the numbers fall further to 84.3, 101.3, 118.3, and 72.7.

The percentage drops are telling. For High settings, stepping from 1080p to 1440p reduces FPS by roughly 36% (from 248.8 to 158.8), and from 1440p to 4K, it drops another 47% (to 84.3). For Ultra, the drop from 1080p to 1440p is about 34% (203.6 to 134.2), and from 1440p to 4K, it's another 46% (to 72.7). These consistent reductions suggest that the GPU's rendering load scales with pixel count, which is expected.

The fact that the CPU is not the bottleneck is evident in the 1080p results, where even the most demanding preset (Ultra) stays above 200 FPS. If the CPU were limiting, we would expect frame rates to plateau or show smaller differences between resolutions. Instead, the data shows that the Radeon RX 7900 XT's performance scales down smoothly as resolution increases, with the 4K numbers dropping below 100 FPS on High and Ultra. This indicates that at 4K, the GPU is working near its limits, while the Ryzen 5 7600 has ample headroom. The GPU's 20 GB of GDDR6 memory and 800.0 GB/s bandwidth are likely sufficient for Doom's textures, even at 4K, so the FPS drop is more about pixel throughput than memory capacity.

Measured FPS Breakdown — resolution by resolution, settings by settings, exact numbers

The measured FPS data provides a complete picture of performance across three resolutions and four settings presets. At 1920x1080, the combo delivers 336 FPS on Low, 294.5 on Medium, 248.8 on High, and 203.6 on Ultra. These numbers are all above 200 FPS, making the experience extremely smooth on any high-refresh-rate monitor. The gap between Low and Ultra is 132.4 FPS, showing that settings have a substantial impact even at this resolution.

At 2560x1440, the performance remains strong but shows the expected reduction. Low settings produce 217.8 FPS, Medium 188.8, High 158.8, and Ultra 134.2. The spread between Low and Ultra is narrower in percentage terms (about 38% lower for Ultra compared to Low), which suggests the GPU is becoming more of a factor. Still, all presets stay above 134 FPS, ensuring a smooth experience on 1440p displays.

At 3840x2160, the frame rates drop more significantly. Low settings yield 118.3 FPS, Medium 101.3, High 84.3, and Ultra 72.7. Here, the gap between Low and Ultra is 45.6 FPS, and the Ultra preset finally dips below the 75 FPS threshold, which may be noticeable on some displays. The data indicates that 4K gaming at Ultra is possible but not ideal for high refresh rates, while Low settings at 4K still manage to exceed 115 FPS.

Across all resolutions, the pattern is consistent: Low settings provide the highest FPS, followed by Medium, High, and then Ultra. The relative differences between settings are larger at lower resolutions, likely because the GPU has more spare capacity when pixel count is lower. For example, at 1080p, Ultra is 39% slower than Low, while at 4K, Ultra is 39% slower as well, showing a similar proportional impact.

How This Combo Ranks — use comboRankInGame vs other tested combos

In the database of tested CPU-GPU combinations for Doom, this pairing of the AMD Ryzen 5 7600 and AMD Radeon RX 7900 XT ranks 381st out of 1681 total combos. This places it in the top 22.7% of all tested systems, which is a solid showing given the large number of possible configurations. The rank reflects the overall performance across all settings and resolutions, not just a single benchmark.

The ranking is notable because the GPU alone sits in the 82nd percentile vs all GPUs, and the CPU is in the 83rd percentile. Yet the combined rank is not in the top 100, suggesting that other factors, such as CPU-GPU balance or specific game optimizations, might influence the outcome. For a game like Doom, which is well-optimized, the rank of 381 suggests that many higher-end combos (likely with more powerful GPUs or CPUs) achieve better average FPS.

However, the delta between this combo and its nearest rivals is minimal. The GPU's nearest rival, the NVIDIA GeForce RTX 5080 Mobile, has a deltaPct of 0, meaning they perform nearly identically in synthetic benchmarks. Similarly, the CPU's rivals are within 0.3% of its average score. This implies that in real-world gaming, the differences between this combo and others in its vicinity are likely small, and the rank may be sensitive to minor variations in test conditions.

The rank of 381 out of 1681 also indicates that this combo is not a top-tier performer for competitive 4K gaming, but it is well above average. For 1080p and 1440p, the measured FPS are high enough to rank favorably, but the 4K results, particularly on Ultra, pull the overall rank down. Users seeking the absolute highest frame rates at 4K might need to consider higher-end GPUs, but for most gaming scenarios, this combo is competitive.

Settings Recommendations — which preset gives the best experience per the measured rows

Based on the measured FPS data, the optimal settings preset depends on the target resolution and desired frame rate. At 1920x1080, all presets exceed 200 FPS, so the choice is between visual fidelity and raw speed. Ultra at 203.6 FPS offers the best image quality while still providing an excellent experience for high-refresh-rate monitors. If the goal is to maximize FPS for competitive play, Low at 336 FPS is the clear choice, but the visual trade-off may be significant.

At 2560x1440, the data suggests that High or Ultra are the best options. High delivers 158.8 FPS, which is above the threshold for most 144Hz displays, while Ultra at 134.2 FPS still feels smooth. Medium at 188.8 FPS provides a middle ground, but the visual improvement from Medium to High is likely worth the 30 FPS drop. Low at 217.8 FPS is overkill for most 1440p monitors, so it's not recommended unless the user has a 240Hz display.

At 3840x2160, the recommendations change. Low at 118.3 FPS is the only preset that comfortably exceeds 100 FPS, making it the best choice for 4K gaming on a 120Hz or 144Hz display. Medium at 101.3 FPS is also viable, but High at 84.3 FPS and Ultra at 72.7 FPS may introduce noticeable stutter on higher refresh rate panels. For 4K, prioritizing frame rate over visual details is advisable, given that the GPU is clearly the limiting factor at this resolution.

Overall, the best experience hinges on resolution. For 1080p, Ultra is recommended for its balance of quality and speed. For 1440p, High offers the best compromise, with 158.8 FPS and good visuals. For 4K, Low or Medium are the practical choices, as they keep FPS above 100, ensuring smooth gameplay. The data does not support using Ultra at 4K, as the 72.7 FPS average may be below the refresh rate of many modern monitors.

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

The AMD Radeon RX 7900 XT is a high-end GPU based on the RDNA 3.0 architecture, with a chip codenamed Plum Bonito and built on TSMC's 5 nm process. It features 20 GB of GDDR6 memory on a 320-bit bus, providing a bandwidth of 800.0 GB/s. The GPU's boost clock is 2394 MHz, with a game clock of 2025 MHz, and it has 5376 shading units, 336 TMUs, and 192 ROPs. These specifications place it in the 82nd percentile vs all GPUs, with an average benchmark score of 38358.

In Doom, the GPU's role is evident from the frame rates at different resolutions. At 1080p, the GPU is not stressed, as even Ultra settings yield 203.6 FPS. This suggests that the RX 7900 XT has significant headroom at lower resolutions, and the CPU is capable of keeping up. At 1440p, the GPU begins to show its strength, with High at 158.8 FPS and Ultra at 134.2 FPS, still well above playable thresholds.

At 4K, the GPU becomes the limiting factor. The 20 GB VRAM is more than sufficient for Doom's textures, which are not notoriously demanding by modern standards, but the pixel throughput required at 3840x2160 stresses the GPU's compute units. The measured FPS at 4K range from 118.3 on Low to 72.7 on Ultra, indicating that the GPU's rendering capabilities are the primary constraint. The memory bandwidth of 800.0 GB/s likely helps maintain consistent performance, but the raw pixel rate of 459.6 GPixel/s and texture rate of 804.4 GTexel/s are what determine the frame rates at high resolutions.

The GPU's nearest rivals in synthetic benchmarks include the NVIDIA GeForce RTX 5080 Mobile (deltaPct 0) and the NVIDIA GeForce RTX 4080 Mobile (deltaPct 0.6), showing that the RX 7900 XT is competitive with top-tier mobile GPUs. However, in Doom, the desktop GPU's performance is more relevant, and the data shows it excels at 1080p and 1440p, while being adequate but not exceptional at 4K. The GPU's 51.48 TFLOPS of FP32 compute power is clearly leveraged by Doom's engine, which is known for its scalability across GPU architectures.
