Doom

The AMD Ryzen 7 5800XT paired with the NVIDIA GeForce RTX 4070 Ti delivers a formidable 1080p and 1440p experience in Doom, but the data reveals a clear transition point where the GPU becomes the primary constraint. At 1080p, the combination produces frame rates well beyond the refresh rate of typical high-end monitors, while 4K performance remains respectable but demands settings adjustments to maintain high refresh rates.

Resolution Scaling

The measured FPS data shows a predictable decline as resolution increases, but the rate of that decline reveals the balance between the CPU and GPU. At 1080p with Low settings, the combo achieves 368 FPS, which drops to 238 FPS at 1440p and further to 129 FPS at 4K. This represents a 35% reduction from 1080p to 1440p and a 65% reduction from 1080p to 4K, indicating that the scaling is not perfectly linear and that the GPU workload grows disproportionately at higher resolutions.

The transition from High settings at 1080p (271 FPS) to High at 1440p (175 FPS) shows a 35% drop, while the move from 1440p High to 4K High (95 FPS) incurs a 46% reduction. This steeper decline at 4K suggests that the RTX 4070 Ti's memory bandwidth and shading throughput become limiting factors, as the pixel count quadruples from 1080p to 4K but the frame rate does not halve proportionally. The data indicates that at 1080p, the CPU is likely the bottleneck, given that the FPS scales almost linearly with resolution decreases when settings are held constant.

At Ultra settings, the pattern is consistent: 221 FPS at 1080p, 143 FPS at 1440p, and 78 FPS at 4K. The 1080p to 1440p drop is 35%, identical to the High preset, while the 1440p to 4K drop is 45%. This consistency across presets suggests that the resolution scaling behavior is primarily driven by GPU fill rate and memory bandwidth rather than shader complexity, since the relative performance gaps remain stable regardless of graphical fidelity.

GPU Role

The NVIDIA GeForce RTX 4070 Ti features 12 GB of GDDR6X memory on a 192-bit bus, delivering 504.2 GB/s of bandwidth. This memory configuration is sufficient for Doom at all tested resolutions and settings, as the game's texture requirements are moderate by modern standards. The GPU's 7680 shading units and 80 ROPs provide substantial pixel throughput, with a pixel rate of 208.8 GPixel/s that helps maintain high fill rates even at 4K.

The GPU clocks operate at a base of 2310 MHz with a boost of 2610 MHz, and the memory runs at 1313 MHz with 21 Gbps effective speed. These clock speeds, combined with the Ada Lovelace architecture's efficiency, allow the card to sustain high frame rates without thermal throttling. The RTX 4070 Ti's 285 W TDP and dual-slot design indicate a power-hungry part, but the data shows it delivers consistent performance across all measured scenarios.

The benchmark results position this GPU at the 84th percentile among all GPUs, with an average benchmark score of 44795. Its nearest rivals include the NVIDIA GeForce RTX 5090 Mobile (45152, delta -0.8%), AMD Radeon Pro 5500 XT (45384, delta -1.3%), and Intel Arc A730M (45592, delta -1.7%). This indicates the RTX 4070 Ti sits slightly below these mobile and workstation parts in raw compute, but its desktop-oriented design with higher sustained clocks likely contributes to the strong gaming performance observed in Doom.

How This Combo Ranks

This specific combination of AMD Ryzen 7 5800XT and NVIDIA GeForce RTX 4070 Ti ranks 461 out of 3712 tested combos in Doom, placing it in the top 12.4% of all configurations. This high ranking reflects the synergy between the 8-core, 16-thread CPU and the 40-series GPU, which together produce frame rates that exceed the requirements of most displays.

The CPU's average benchmark score of 29879 places it at the 81st percentile among all processors, with nearest rivals including the AMD Ryzen 7 7840H (29868, delta 0%), AMD Ryzen 7 8845HS (29955, delta -0.3%), AMD Ryzen 7 7840HS (29955, delta -0.3%), and AMD Ryzen 5 9600X (29713, delta 0.6%). These rivals are all mobile or newer desktop parts, yet the 5800XT holds its own within a fraction of a percent, demonstrating that its Zen 3 architecture remains competitive for gaming workloads.

The combo rank of 461 indicates that while this pairing is strong, there are 460 configurations that achieve higher performance in Doom. This is likely due to more recent CPUs with higher single-thread performance or GPUs with more memory bandwidth, as the game responds well to both CPU frequency and GPU fill rate. However, the gap between this combo and the top performers is not enormous, given that the rank is in the 12th percentile of all tested combinations.

Measured FPS Breakdown

At 1920x1080, the combo delivers exceptional performance across all presets. Low settings produce 368 FPS average, Medium yields 321 FPS with a minimum of 273 and maximum of 369, High achieves 271 FPS, and Ultra drops to 221 FPS. The spread from Low to Ultra is 147 FPS, representing a 40% reduction in frame rate when maxing out graphics quality. This indicates that even at Ultra settings, the system has substantial headroom for high refresh rate displays.

Moving to 2560x1440, the performance remains very strong but shows more sensitivity to settings. Low settings produce 238 FPS, Medium averages 208 FPS with a minimum of 176 and maximum of 239, High reaches 175 FPS, and Ultra settles at 143 FPS. The Low to Ultra spread is 95 FPS, a 40% reduction consistent with the 1080p pattern. The minimum frame rates at Medium (176 FPS) suggest that even in demanding scenes, the system maintains smooth gameplay.

At 3840x2160, the combo transitions from high refresh rate territory to standard 60-120 Hz performance. Low settings yield 129 FPS, Medium averages 112 FPS with a minimum of 96 and maximum of 129, High produces 95 FPS, and Ultra drops to 78 FPS. The Low to Ultra spread is 51 FPS, a 40% reduction that mirrors the lower resolutions. The minimum FPS at 4K Medium (96) is still above 60, ensuring a playable experience even in the most demanding moments.

CPU Role

The AMD Ryzen 7 5800XT provides 8 cores and 16 threads based on the Zen 3 architecture, codenamed Vermeer, manufactured on TSMC's 7 nm process. The CPU operates with a base clock of 3.80 GHz and a boost clock of 4.80 GHz, with a 105 W TDP. This configuration delivers strong multi-threaded performance, as evidenced by a Cinebench R23 multicore score of 23794 and a single-core score of 3359.

For Doom, the CPU's single-thread performance is particularly relevant, as the game engine relies heavily on a few primary threads for game logic and rendering commands. The 3DMark single-thread score of 959 and PassMark single-thread score of 3535 indicate that the 5800XT's per-core performance is competitive, allowing it to feed the RTX 4070 Ti efficiently at lower resolutions where the GPU is not the bottleneck.

The CPU's 32 MB of shared L3 cache helps reduce memory latency, which is beneficial for game workloads that exhibit spatial and temporal locality. The dual-channel DDR4 memory support with 51.2 GB/s bandwidth is adequate for this game, as the measured FPS at 1080p exceeds 360 in Low settings, suggesting that memory bandwidth is not a limiting factor. The PCIe Gen 4 interface with 20 lanes provides sufficient bandwidth for the GPU, though Doom does not heavily utilize PCIe transfers during typical gameplay.

Settings Recommendations

Based on the measured FPS data, the optimal settings depend on the target resolution and display refresh rate. At 1080p, the Ultra preset at 221 FPS is the best choice for users with 240 Hz monitors, as it provides the highest visual fidelity while still exceeding the refresh rate of most displays. For 144 Hz monitors, the High preset at 271 FPS offers a substantial quality improvement over Medium while maintaining more than double the refresh rate, making it the best balance of image quality and performance.

At 1440p, the High preset at 175 FPS is recommended for 165 Hz or 175 Hz displays, as it delivers smooth gameplay with good visual quality. For 144 Hz monitors, the Ultra preset at 143 FPS is the ideal choice, providing the maximum graphical detail while staying just above the refresh rate threshold. Users with 240 Hz displays should consider the Medium preset at 208 FPS, which offers a significant performance boost over High while still providing acceptable visual quality.

At 4K, the Medium preset at 112 FPS is the best option for displays with 120 Hz refresh rates, as it maintains frame rates above the display's capability while offering balanced visual quality. For 60 Hz displays, the Ultra preset at 78 FPS provides the highest fidelity experience, though the High preset at 95 FPS offers a smoother experience with only a modest reduction in visual quality. The Low preset at 129 FPS is unnecessary for most 4K displays, as even the Medium preset provides sufficient performance for standard refresh rates.
