Doom

The AMD Ryzen 7 5700X and NVIDIA GeForce RTX 4080 combination delivers exceptional performance in Doom, placing in the top percentile of tested hardware configurations. This pairing leverages the 8-core Zen 3 processor and the Ada Lovelace GPU to produce frame rates that consistently exceed high-refresh-rate display capabilities, even at demanding resolutions. The benchmark data reveals a system where the GPU is the primary driver of performance scaling, with the CPU providing ample headroom to avoid bottlenecks.

Resolution Scaling

The performance drop from 1080p to 4K is significant but predictable for a GPU-bound title like Doom. At 1080p with High settings, the combo produces 295 FPS on average. Moving to 1440p, the average drops to 191 FPS, a reduction of 104 FPS. At 4K, the average falls further to 104 FPS. This scaling pattern indicates that the game becomes increasingly dependent on the RTX 4080's raw rendering power as pixel count rises.

The data shows a clear trend: between 1080p and 1440p, the frame rate drops by approximately 35%. The jump from 1440p to 4K results in a 45% reduction in average FPS. This non-linear decline suggests that at 4K, the GPU's memory bandwidth and shading throughput are being taxed more heavily. The RTX 4080's 716.8 GB/s of memory bandwidth and 48.74 TFLOPS of FP32 compute are sufficient to maintain playable frame rates, but the headroom shrinks considerably.

When comparing Low settings across resolutions, the pattern holds. At 1080p Low, the system reaches 355 FPS. At 1440p Low, it achieves 260 FPS, and at 4K Low, it produces 141 FPS. The relative performance gap between Low and Ultra settings also widens with resolution. At 1080p, Ultra delivers 241 FPS versus 355 FPS on Low, a 32% difference. At 4K, Ultra produces 85 FPS versus 141 FPS on Low, a 40% difference. This indicates that the visual effects enabled by Ultra settings place a proportionally larger load on the GPU at higher resolutions.

GPU Role

The NVIDIA GeForce RTX 4080 is the dominant component in this configuration, as evidenced by the frame rate scaling across resolutions. The GPU's 16 GB of GDDR6X memory is more than sufficient for Doom, a title that does not require excessive VRAM capacity. The 256-bit memory bus and 716.8 GB/s bandwidth ensure that texture streaming and high-resolution assets do not create bottlenecks. The benchmark results show no signs of memory capacity limitations, even at 4K Ultra where the GPU is most stressed.

The clock speeds of the RTX 4080, with a base of 2205 MHz and a boost of 2505 MHz, contribute to its strong performance. The Ada Lovelace architecture, built on a 5 nm process, delivers high efficiency that allows these clocks to sustain under load. The GPU's 9728 shading units and 304 texture mapping units process Doom's geometry and effects with ease. The passmark g3d score of 34457 and 3dmark steel nomad score of 6567 reflect the GPU's raw capability.

The RTX 4080's performance relative to its nearest rivals is tight. It scores 54247 on average, which is 0.1% behind the RTX 4080 SUPER and 1.1% ahead of the AMD Radeon Pro W5700X. The delta to the RX 6750 GRE 12 GB is 2.6%, showing that the 4080 is competitive but not dominant in synthetic benchmarks. In Doom specifically, the measured FPS indicates that the GPU's architecture is well-suited to the game's Vulkan-based rendering engine.

CPU Role

The AMD Ryzen 7 5700X plays a supporting role in this combination, providing enough processing power to keep the RTX 4080 fed. With 8 cores and 16 threads based on the Zen 3 architecture, the CPU handles Doom's game logic and physics without becoming the limiting factor. The CPU's boost clock of 4.60 GHz and base clock of 3.40 GHz are adequate for maintaining high frame rates, as evidenced by the 355 FPS result at 1080p Low.

The CPU's benchmark scores show it is a capable mid-range processor. Its cinebench r23 multicore score of 13184 and single-core score of 1499 place it well within the range needed for modern FPS titles. The geekbench multicore score of 10779 and single-core score of 2016 further confirm its balanced performance. The CPU's passmark multithread score of 26612 and single-thread score of 3385 indicate that it can handle both lightly threaded and fully threaded workloads.

The Ryzen 7 5700X's nearest rivals show that it is competitive in its class. It scores 27578 on average, matching the Intel Core i5-12600K exactly. The AMD Ryzen 7 5800 is 0.2% behind, while the Ryzen 5 7600X is 0.2% ahead. This tight grouping suggests that the CPU is not a differentiator in this system; the GPU is the primary driver of performance. The CPU's 32 MB of shared L3 cache helps reduce memory latency, which benefits game performance.

Measured FPS Breakdown

At 1080p, the system delivers exceptionally high frame rates across all settings. Low settings produce 355 FPS, Medium produces 338 FPS, High produces 295 FPS, and Ultra produces 241 FPS. The Medium setting shows a minimum of 287 FPS and a maximum of 389 FPS, indicating some variance but no significant stuttering. These numbers are far beyond the refresh rate of most monitors, making the CPU the potential limiting factor at this resolution, though the data does not show any CPU bottleneck.

Moving to 1440p, the frame rates remain high but show the GPU taking on more work. Low settings yield 260 FPS, Medium yields 226 FPS, High yields 191 FPS, and Ultra yields 156 FPS. The Medium setting has a minimum of 192 FPS and a maximum of 260 FPS. This resolution is the sweet spot for this combination, as it provides high frame rates that can fully utilize 144Hz or 165Hz displays while maintaining visual quality.

At 4K, the system still performs admirably but requires settings adjustments for the smoothest experience. High settings produce 104 FPS, which is playable but not ideal for competitive play. Medium settings produce 123 FPS with a minimum of 104 FPS and a maximum of 141 FPS, suggesting that Medium is the best balance at this resolution. Low settings reach 141 FPS, while Ultra drops to 85 FPS, which is noticeably lower. The data suggests that 4K gaming is viable with this combo, but users must accept either reduced settings or lower frame rates.

However, the gap in performance is likely small, as the RTX 4080 is a high-end GPU. The Ryzen 7 5700X does not hold back the GPU significantly, as demonstrated by the high frame rates at 1080p where CPU load is highest. The data indicates that this combo is well-balanced for Doom, with neither component being a clear weak point.

When considering the percentile rankings, the CPU is in the 79th percentile of all CPUs, while the GPU is in the 86th percentile of all GPUs. The combo's rank in Doom is higher than what either component's percentile would suggest, indicating that the game is well-optimized for this hardware. This suggests that Doom's Vulkan rendering scales well with the RTX 4080's architecture, allowing the combo to punch above its weight in synthetic benchmarks.

Settings Recommendations

For the best experience at 1440p, High settings at 191 FPS is the recommended choice. This provides a significant visual uplift over Medium while maintaining frame rates that exceed most high-refresh-rate monitors. The 156 FPS result at Ultra is also viable, but the 35 FPS gain from dropping to High is noticeable and worth the minor visual compromise. For competitive play, Medium settings at 226 FPS offer a smooth experience with reduced visual effects.

At 4K, Medium settings at 123 FPS is the optimal balance. This provides a playable frame rate with a minimum of 104 FPS, ensuring no major drops below 100 FPS. High settings at 104 FPS are acceptable, but the margin for error is thinner. Ultra settings at 85 FPS may be suitable for slower-paced gameplay, but the drop below 90 FPS can be noticeable. Low settings at 141 FPS are the best for maximum smoothness, but the visual quality is significantly reduced.

At 1080p, the choice depends on the monitor's refresh rate. For 240Hz displays, High settings at 295 FPS are sufficient. For 360Hz displays, Low settings at 355 FPS are necessary to fully utilize the refresh rate. Medium settings at 338 FPS provide a good middle ground, with a minimum of 287 FPS that ensures no drops below 240Hz. Ultra settings at 241 FPS are the best for visual quality, but they do not fully saturate the fastest displays. The data shows that this combo is versatile, offering excellent performance at every resolution with appropriate settings adjustments.
