Doom

This analysis examines the performance of the AMD Ryzen 7 7700 paired with the NVIDIA GeForce RTX 4080 in Doom, based on measured benchmark data. The combination ranks 215th out of 3712 tested configurations, placing it in the top tier for this title. The data reveals a system that is overwhelmingly GPU-bound at higher resolutions, but transitions to a more balanced workload as resolution drops, where the processor's capabilities become increasingly relevant.

Resolution Scaling

The measured FPS data shows a clear and predictable pattern of performance degradation as resolution increases from 1920x1080 to 3840x2160. At the Ultra preset, the average frame rate drops from 241 FPS at 1080p to 156 FPS at 1440p, a reduction of 85 FPS, and then further to 85 FPS at 4K, another 71 FPS lower. This represents a substantial 65% performance loss from 1080p to 4K, indicating that the rendering workload scales heavily with pixel count.

The scaling behavior reveals the limiting component at each resolution. At 4K, the RTX 4080 is clearly the bottleneck, as the frame rate is constrained by the GPU's ability to fill those 8.3 million pixels. The 141 FPS at Low settings versus 85 FPS at Ultra at 4K shows a 56 FPS spread, demonstrating that even with reduced graphical load, the GPU remains the primary constraint. The data suggests that at 4K, the Ryzen 7 7700's 8 cores and 16 threads have ample headroom, and the system's performance is dictated almost entirely by the graphics card.

Moving to 1440p, the picture becomes more balanced. The average FPS at High settings is 191, and at Medium it is 226, with Low hitting 260. The gap between Low and Ultra is 104 FPS, which is larger than at 4K, suggesting the CPU is starting to play a more significant role in feeding the GPU. However, the RTX 4080 still has enough work to keep the processor from being the sole limiting factor. At 1080p, the situation changes dramatically; the CPU's influence becomes much more pronounced, with the frame rates reaching 401 FPS at Low settings, indicating that the GPU is no longer the primary bottleneck and the system is increasingly bound by the processor's single-thread performance.

CPU Role

The AMD Ryzen 7 7700 is an 8-core, 16-thread processor based on the Zen 4 architecture, with a base clock of 3.80 GHz and a boost clock of 5.30 GHz. In Doom, a game that is known for being highly responsive to strong single-core performance, this CPU's specifications are directly relevant. The benchmark data shows that the processor achieves a single-thread score of 1049 in 3DMark and a Passmark single-thread score of 4063, which are strong indicators of its capability to handle the game's primary game logic and draw call processing.

The importance of the CPU is most evident in the 1080p results. At Low settings, the average FPS is 401, which is 106 FPS higher than at High settings (295 FPS). This difference is not due to GPU load, as the RTX 4080 is more than capable of rendering simple scenes at high speed. Instead, it suggests that the CPU's ability to process the game's simulation and submit draw calls is the limiting factor. The 3DMark 8-thread score of 6933 and max-thread score of 8479 indicate that the processor can utilize its full core count when needed, but Doom's engine often does not scale perfectly with all 16 threads.

The Ryzen 7 7700's L3 cache is 32 MB shared, which is a significant amount and helps keep frequently accessed game data close to the cores. This can reduce memory latency and improve frame pacing, contributing to the high minimum FPS observed in the Medium preset at 1440p (192 FPS) and 1080p (297 FPS). Compared to its nearest rivals, the Ryzen 7 7700 has an average benchmark score of 40081, which is 0.1% higher than the AMD Ryzen AI 9 365 and 0.2% lower than the Intel Core 5 221E. This indicates that its overall compute capability is competitive, though the specific single-thread performance, as measured by Cinebench R23 at 1930, is what matters most for Doom's high-FPS scenarios.

Settings Recommendations

For users with a 4K display, the data suggests that the High preset is the optimal choice. It delivers an average of 104 FPS, which is a substantial improvement over the Ultra preset's 85 FPS. The 19 FPS gain from dropping from Ultra to High is significant for smoothness, and the visual difference between these two presets is often minimal in fast-paced action. Pushing to Low at 4K yields 141 FPS, but this may compromise visual fidelity too much for the benefit of higher frame rates, especially if the display is only 60 Hz or 120 Hz.

At 1440p, the High preset is the sweet spot, providing a very smooth 191 FPS average. For competitive players with high refresh rate monitors, the Medium preset at 226 FPS offers a good balance. The Ultra preset at 156 FPS is also playable, but the performance cost of the extra graphical effects is notable. The Low preset at 260 FPS is only recommended for the most competitive scenarios where maximum frame rate is paramount, as the visual downgrade is considerable.

At 1080p, the High preset at 295 FPS is excellent. The Medium preset at 350 FPS is a better choice for users with 360 Hz monitors, while the Low preset at 401 FPS is the absolute maximum the system can achieve. The Ultra preset at 241 FPS is still very fast and will be sufficient for any 240 Hz display. The measured minimum FPS for the Medium preset at 1080p is 297, which ensures that even in intense scenes, the frame rate will not drop below the refresh rate of most high-end monitors.

GPU Role

The NVIDIA GeForce RTX 4080 is the dominant component in this pairing for Doom, particularly at higher resolutions. Its performance is characterized by its Ada Lovelace architecture, 9728 shading units, and a boost clock of 2505 MHz. The GPU's raw compute power, rated at 48.74 TFLOPS for FP32 operations, is the primary driver of the high frame rates observed in the benchmark data. Its 16 GB of GDDR6X memory on a 256-bit bus provides 716.8 GB/s of bandwidth, which is more than sufficient for the textures and assets in Doom.

The RTX 4080's role becomes more pronounced as resolution increases. At 4K, the GPU is working at its limit, as evidenced by the drop from 141 FPS at Low settings to 85 FPS at Ultra. This 56 FPS spread shows that the GPU is highly sensitive to the graphical workload. The pixel rate of 280.6 GPixel/s and texture rate of 761.5 GTexel/s are key specifications that determine how quickly the card can fill the screen with detailed textures. The benchmark results confirm that the RTX 4080 is a very capable 4K card for this title, but users must manage settings to maintain high refresh rates.

The GPU's performance relative to its rivals is also notable. Its average benchmark score is 54247, which is 0.1% higher than the RTX 4080 SUPER's score of 54209, but 1.1% lower than the AMD Radeon Pro W5700X's score of 54828. In practice, this means the RTX 4080 is essentially on par with the SUPER variant for this game, and the differences between it and other high-end cards are minimal. The measured FPS data shows that the GPU is capable of producing over 400 FPS at 1080p Low, which reflects its immense processing power, but its performance is more constrained by the CPU at those settings.

Measured FPS Breakdown

At 1920x1080, the system delivers exceptional performance across all presets. The Low preset yields an average of 401 FPS, with the Medium preset at 350 FPS (minimum 297, maximum 402). High settings produce 295 FPS, and Ultra settings drop to 241 FPS. These numbers indicate that the system is capable of driving the highest refresh rate monitors available, with even the Ultra preset maintaining an average well above 240 FPS.

At 2560x1440, performance remains very high. The Low preset averages 260 FPS, the Medium preset averages 226 FPS (minimum 192, maximum 260), and the High preset averages 191 FPS. The Ultra preset falls to 156 FPS. This resolution is the sweet spot for high-refresh-rate gaming, as the High preset provides a solid 191 FPS average, and the Medium preset is a great choice for competitive play.

At 3840x2160, the system still delivers playable frame rates. The Low preset averages 141 FPS, the Medium preset averages 123 FPS (minimum 104, maximum 141), and the High preset averages 104 FPS. The Ultra preset averages 85 FPS. These results show that 4K gaming is viable, but users will need to compromise on settings to achieve higher refresh rates. The jump from Ultra to High at 4K represents a 19 FPS improvement, which is a meaningful gain for smoothness.
