Doom

The AMD Ryzen 5 5600X paired with the AMD Radeon RX 7700 XT delivers a robust performance profile in Doom, with frame rates that scale predictably across resolutions and settings. The measured data shows a system capable of high refresh rate gaming at 1080p and smooth 60+ FPS experiences at 4K, though the balance between CPU and GPU workloads shifts significantly as resolution increases.

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

The AMD Radeon RX 7700 XT is built on the RDNA 3.0 architecture with a Navi 32 chip, fabricated on a 5 nm process. Its memory subsystem features 12 GB of GDDR6 on a 192-bit bus, delivering 432.0 GB/s of bandwidth. The base clock sits at 1435 MHz, with a boost clock of 2544 MHz and a game clock of 2171 MHz. These specifications translate into substantial raw throughput: 35.17 TFLOPS of FP32 performance, a pixel rate of 244.2 GPixel/s, and a texture rate of 549.5 GTexel/s.

In Doom, the GPU’s role becomes increasingly dominant as resolution climbs. At 1080p, the card’s high pixel and texture rates allow it to push frame rates well beyond 200 FPS at lower settings, with the Ultra preset still achieving 159 FPS. The 12 GB VRAM capacity is more than sufficient for this 2016 title, even at 4K Ultra, eliminating any memory capacity concerns. The measured 4K Ultra average of 56 FPS indicates the GPU is the primary bottleneck at that resolution, as the frame rate drop from 1080p Ultra to 4K Ultra is a steep 64.8% decline, consistent with the increased pixel throughput demand. Boost clock stability is implied by the consistent scaling between settings; the data shows a clear 17.6% performance gain from Ultra to High at 4K (56 to 68 FPS), which aligns with the GPU’s ability to maintain high clock speeds under load.

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

The AMD Ryzen 5 5600X is a Zen 3 (Vermeer) part with 6 cores and 12 threads, base clocked at 3.70 GHz and boosting to 4.60 GHz. It supports DDR4 memory with a dual-channel bus and 51.2 GB/s bandwidth, and its 32 MB L3 cache helps with game-level data locality. In synthetic benchmarks, the CPU scores 917 in 3dMark single-thread, 3363 in 4-thread, and 5588 in max-thread tests. Cinebench R23 results show 1541 single-core and 11838 multi-core.

For Doom, the CPU’s single-thread performance is critical, as the game’s engine relies heavily on a few primary threads. The 3dMark single-thread score of 917 and 2-thread score of 1793 suggest strong per-core throughput, which is reflected in the measured frame rates. At 1080p Low, the system achieves 264 FPS, while at 1080p Ultra it drops to 159 FPS. The fact that 1080p Low (264 FPS) is only 36% higher than 1080p Ultra (159 FPS) indicates that at lower settings, the CPU becomes a more visible limiter, preventing the GPU from reaching even higher frame rates. Conversely, at 4K Low (93 FPS) versus 4K Ultra (56 FPS), the 66% spread shows the GPU is the clear constraint. The 12 threads ensure the game’s background tasks and driver overhead do not create stutter, as evidenced by the minimum FPS of 196 at 1080p Medium, which is close to the 230 average.

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

The measured data provides a clear picture of how the system scales across 1920x1080, 2560x1440, and 3840x2160. At High settings, the average frame rates are 194, 126, and 68 FPS respectively. This represents a 35.1% drop from 1080p to 1440p, and a further 46.0% drop from 1440p to 4K. The total decline from 1080p to 4K High is 64.9%, which is close to the theoretical pixel count increase (4x), indicating the GPU is the dominant factor at higher resolutions.

At Low settings, the scaling is different: 264 FPS at 1080p, 171 FPS at 1440p, and 93 FPS at 4K. The drop from 1080p to 1440p is 35.2%, but from 1440p to 4K it is 45.6%. The 1080p Low result of 264 FPS is likely near the CPU’s maximum frame delivery capability for this game, given that the 1440p Low result is 171 FPS (a 35% reduction, matching the pixel ratio). The 4K Low result of 93 FPS is exactly 35% lower than 1440p Low, again matching pixel count scaling. This consistency suggests that beyond 1080p, the GPU is the primary limiter even at Low settings, while at 1080p Low, the CPU is approaching its ceiling. Medium settings show a similar pattern: 230 FPS at 1080p, 149 FPS at 1440p, and 81 FPS at 4K, with the 1080p to 1440p drop at 35.2% and 1440p to 4K at 45.6%.

FAQ

Q: What is the best resolution for this system in Doom?

A: The data shows 2560x1440 as the sweet spot. At High settings, it achieves 126 FPS, which is well above 60 FPS and nearly double the 4K result of 68 FPS, while still providing a significant visual upgrade over 1080p.

Q: How does the system perform at 4K Ultra settings?

A: The measured average FPS for 4K Ultra is 56 FPS. This is playable but not ideal for high refresh rate monitors, as it dips below the 60 FPS threshold.

Q: Is the CPU or GPU the bottleneck at 1080p?

A: At 1080p Low, the system hits 264 FPS, but the drop to Ultra (159 FPS) is only 39.8%. This relatively small gap suggests the CPU is limiting at lower settings, preventing the GPU from fully stretching its legs.

Q: What are the minimum FPS values recorded?

A: Minimum FPS data is available for Medium settings only. At 1920x1080 Medium, the minimum is 196 FPS; at 2560x1440 Medium, it is 127 FPS; and at 3840x2160 Medium, it is 69 FPS.

Q: How does the RX 7700 XT compare to its nearest GPU rival?

A: The RX 7700 XT’s avg benchmark score is 22549, which is 0.5% higher than the NVIDIA GeForce RTX 5060 Mobile (22435) and 1.7% higher than the AMD Radeon RX 5700 (22170). It trails the RTX 4060 Mobile (22729) by 0.8%.

Q: Does this system support high refresh rates at 1440p?

A: Yes, at 1440p High settings, the average FPS is 126, and at Medium it is 149. These numbers are suitable for 144Hz displays, assuming the monitor supports FreeSync or similar adaptive sync technology.

Settings Recommendations

For the best balance of visual fidelity and performance, the High preset at 2560x1440 is the recommended configuration. It delivers 126 FPS average, which is 35% higher than the 4K High result and only 15% lower than the 1440p Medium result. The jump from Medium to High at 1440p costs 23 FPS (149 to 126), but the visual improvements in a fast-paced FPS like Doom are worth that trade-off for most users.

For players prioritizing maximum frame rates on a 1080p 240Hz monitor, the Low preset at 1920x1080 achieves 264 FPS, which is within reach of 240Hz refresh rates. However, the Medium preset at 230 FPS offers a better visual experience while still exceeding 200 FPS. At 4K, the High preset (68 FPS) is preferable over Ultra (56 FPS) for smoother gameplay, as the 21.4% performance gain outweighs the marginal visual differences in this title. The Low preset at 4K (93 FPS) is an option for those who prioritize frame rate over resolution, but the Medium preset (81 FPS) is a more balanced choice.

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

At 1920x1080, the system delivers its highest frame rates. The Low preset averages 264 FPS, Medium averages 230 FPS with a minimum of 196 FPS and maximum of 265 FPS, High averages 194 FPS, and Ultra averages 159 FPS. The spread from Low to Ultra is 105 FPS, indicating a wide range of performance headroom.

At 2560x1440, performance remains strong. Low averages 171 FPS, Medium averages 149 FPS with a minimum of 127 FPS and maximum of 171 FPS, High averages 126 FPS, and Ultra averages 103 FPS. The drop from 1080p to 1440p is consistent across settings, roughly 35%, which aligns with the increased pixel count.

At 3840x2160, the GPU becomes the clear limiting factor. Low averages 93 FPS, Medium averages 81 FPS with a minimum of 69 FPS and maximum of 93 FPS, High averages 68 FPS, and Ultra averages 56 FPS. The Ultra preset at 4K is the only configuration that falls below 60 FPS, making it marginal for smooth gameplay. The Medium preset’s minimum of 69 FPS shows that even with fluctuations, the system maintains playable frame rates at 4K.
