Doom

The AMD Ryzen 7 5800XT and NVIDIA GeForce RTX 5080 combination delivers a dominant performance profile in Doom, placing in the 80th position out of 1681 tested combos. This pairing is exceptionally well-balanced for the game, with the CPU providing ample single-thread headroom and the GPU scaling predictably across resolutions. The benchmark data clearly shows that this system is built for high-refresh-rate 1440p gameplay and remains highly playable at 4K, though the frame rate curve reveals where each component’s influence begins and ends.

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

The AMD Ryzen 7 5800XT is an 8-core, 16-thread processor based on the Zen 3 architecture, with a base clock of 3.80 GHz and a boost clock of 4.80 GHz. In Doom, a title known for its efficient Vulkan-based engine, the CPU's job is to feed the GPU with draw calls and physics data without becoming a bottleneck. The data suggests it does this effectively. At 1080p with Low settings, the system reaches 368.1 FPS, which is the highest frame rate recorded in the entire dataset. This indicates that the CPU's single-thread performance, bolstered by a 32 MB L3 cache, is more than sufficient to keep the RTX 5080 busy even at lower graphical loads where the GPU is not the primary constraint.

The processor’s multi-threading capabilities also play a role in maintaining stability. While Doom does not heavily utilize all 16 threads, the 3DMark benchmarks show a strong scaling from 3603 points at 4 threads to 6141 points at 8 threads, and a near-linear jump to 7683 points at 16 threads. This headroom ensures that background tasks or heavy game logic do not cause frame hitches. The CPU's 86th percentile ranking among all tested processors, alongside its nearest rival, the AMD Ryzen 7 PRO 5755GE (which is only 0.1% ahead in average score), confirms that this chip sits comfortably in the upper tier of gaming CPUs for this title.

However, the CPU's role becomes less critical as resolution increases. The transition from 1080p to 1440p shows the frame rate dropping by about 34% at High settings (from 313.8 to 204.7 FPS), which is a classic sign of the GPU taking over the primary workload. By 4K, the CPU is rarely the limiting factor, as the GPU is fully saturated. The 5800XT’s 105W TDP and AM4 socket compatibility make it a sensible pairing for this GPU, providing enough throughput without requiring a platform overhaul, though the data does not suggest it needs any overclocking to achieve these results.

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

The NVIDIA GeForce RTX 5080 is the dominant force in this pairing, and its 16 GB of GDDR7 memory on a 256-bit bus with 960.0 GB/s of bandwidth is a critical asset for Doom at high resolutions. The GPU’s base clock of 2295 MHz and boost clock of 2617 MHz, combined with 10752 shading units, allow it to push massive pixel rates. The data confirms this: even at 4K Ultra settings, the system maintains an average of 92 FPS, which is a demanding scenario for most hardware. The 89th percentile ranking among all GPUs, with a 2.5% lead over the Intel Arc A580, shows that the RTX 5080 is a top-tier performer.

The memory capacity proves sufficient for the game’s texture-heavy environments. At 4K Ultra, the frame rate drops to 92 FPS, but there is no evidence of stuttering or memory paging in the data, suggesting the 16 GB VRAM buffer is adequate for the highest settings. The GPU’s bandwidth also helps maintain consistent frame times, as seen in the smooth progression from Low to Ultra settings at each resolution. For instance, at 1440p, moving from Low (273.4 FPS) to High (204.7 FPS) shows a performance cost of roughly 25%, which is reasonable for the visual uplift provided.

The RTX 5080’s architecture also handles the game’s compute shaders efficiently. The FP32 throughput of 56.28 TFLOPS ensures that lighting and post-processing effects do not cause severe frame rate penalties. The data shows that the difference between Medium and High settings is smaller than the jump to Ultra. At 1080p, Medium yields 349.9 FPS, while High yields 313.8 FPS, a 10% drop; however, moving to Ultra costs another 18.5% (down to 255.5 FPS). This indicates that the Ultra preset introduces effects that heavily tax the GPU, but the RTX 5080 still delivers playable results. The GPU is clearly the primary driver of performance variance in this pairing, with the CPU providing a stable platform beneath it.

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

The measured data suggests that the High preset offers the optimal balance of visual fidelity and frame rate for this combination. At 1440p, High settings produce an average of 204.7 FPS, which is well above the 144 Hz refresh rate typical of high-end monitors, while Ultra drops to 164.4 FPS—still excellent but with diminishing returns on visual quality for a 20% performance loss. For competitive play, the Low preset at 1080p (368.1 FPS) is the clear choice, as it minimizes rendering overhead and maximizes responsiveness.

At 4K, the recommendation shifts based on preference. High settings yield 107.6 FPS, which is ideal for a 120 Hz display, while Ultra drops to 92 FPS, which is still playable but sacrifices the smoothness that the High preset provides. The Medium preset (130.9 FPS at 4K) offers a middle ground, but the data shows that High is only a 17.8% performance hit over Medium while providing noticeably better image quality. Therefore, for most users, High is the recommended preset across all resolutions. It provides a 25% performance margin over Ultra at 1080p (313.8 FPS vs 255.5 FPS) and a 17% margin at 1440p (204.7 FPS vs 164.4 FPS), making it the most efficient use of the hardware’s capabilities.

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

At 1920x1080, the system delivers its highest performance. The Low preset produces 368.1 FPS, Medium produces 349.9 FPS, High produces 313.8 FPS, and Ultra produces 255.5 FPS. The progression shows a 6.8% drop from Low to Medium, a 10.3% drop from Medium to High, and a 18.6% drop from High to Ultra.

Moving to 2560x1440, the frame rates remain high but show a clear scaling penalty. Low yields 273.4 FPS, Medium yields 239.0 FPS, High yields 204.7 FPS, and Ultra yields 164.4 FPS. The percentage drops are 12.6% from Low to Medium, 14.4% from Medium to High, and 19.7% from High to Ultra.

At 3840x2160, the system still delivers excellent results. Low produces 146.4 FPS, Medium produces 130.9 FPS, High produces 107.6 FPS, and Ultra produces 92.0 FPS. The drops are 10.6% from Low to Medium, 17.8% from Medium to High, and 14.5% from High to Ultra. The absolute numbers show that even the most demanding setting combination (4K Ultra) remains above 90 FPS, making this a viable 4K gaming system.

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

The data reveals a clear pattern of GPU-bound scaling. Moving from 1080p to 1440p at High settings, the frame rate drops from 313.8 FPS to 204.7 FPS, a 34.8% reduction. This is a typical result for a GPU-intensive workload, as the number of pixels increases by 78% but the frame rate does not drop proportionally, indicating that the GPU has headroom to spare at 1080p. The CPU is not the bottleneck here, as the frame rates remain high enough to suggest the GPU is the primary constraint.

The scaling from 1440p to 4K is even more pronounced. At High settings, the frame rate drops from 204.7 FPS to 107.6 FPS, a 47.4% reduction. This steep drop confirms that the RTX 5080 is being pushed to its limits at 4K. The pixel count quadruples from 1080p to 4K, yet the frame rate at High settings drops by 65.7% (from 313.8 to 107.6 FPS). This non-linear scaling indicates that the GPU’s memory bandwidth and compute resources are the limiting factors, not the CPU.

At Low settings, the scaling is similar. The frame rate drops from 368.1 FPS at 1080p to 273.4 FPS at 1440p (a 25.7% drop), and then to 146.4 FPS at 4K (a 46.4% drop from 1440p). The fact that the frame rate still drops significantly even at Low settings suggests that the GPU is always the primary determinant of performance in this pairing. The CPU’s influence is minimal, as evidenced by the high frame rates at 1080p where CPU overhead would typically be more visible. This analysis confirms that the RTX 5080 is the dominant component, and the Ryzen 7 5800XT provides ample support without becoming a bottleneck at any resolution or setting combination.
