Doom

How This Combo Ranks

The AMD Ryzen 9 7900X paired with the NVIDIA GeForce RTX 3070 Ti ranks 1333rd out of 3712 tested combinations in Doom, placing it in the top 36% of all systems evaluated. This is a strong result for a game from 2016, indicating that this hardware combination provides a comfortable performance envelope for the title. The ranking reflects the balance between the CPU's high multithreaded capability and the GPU's mid-to-high tier standing among all tested graphics cards.

The CPU itself sits at the 91st percentile among all processors, with an average benchmark score of 53,288. Its nearest rivals in the synthetic CPU benchmarks are the AMD EPYC 7313P (0.2% ahead), the Intel Xeon Phi 7290 (0.3% behind), the Intel Xeon 634 (0.6% ahead), and the Intel Core i7-14700F (0.6% behind). The GPU, meanwhile, holds the 75th percentile among all graphics cards, with an average benchmark score of 29,945, and its closest competitors include the NVIDIA GeForce RTX 5070 Mobile (0.1% ahead), the AMD Radeon RX 6800 (0.5% behind), the NVIDIA GeForce RTX 2080 Ti (0.5% ahead), and the AMD Radeon RX 6700 (1.6% behind).

The combination's rank in Doom is better than what the raw component percentiles might suggest. This is because Doom's engine scales well across a broad range of hardware, and the measured frame rates at every resolution and settings preset are well above playable thresholds. The data indicates that this system is not struggling in any configuration tested, which is a notable achievement given the GPU's 8 GB VRAM capacity and the game's high refresh rate potential.

GPU Role

The NVIDIA GeForce RTX 3070 Ti is built on the Ampere architecture with a GA104 chip fabricated on Samsung's 8 nm process. It carries 17,400 million transistors on a 392 mm² die. The card operates at a base clock of 1575 MHz and a boost clock of 1770 MHz, with memory clocked at 1188 MHz (19 Gbps effective). Memory configuration consists of 8 GB of GDDR6X on a 256-bit bus, yielding a bandwidth of 608.3 GB/s. The GPU has 6144 shading units, 192 texture mapping units, 96 raster operation units, 48 ray tracing cores, and 192 tensor cores. Pixel rate is 169.9 GPixel/s, texture rate is 339.8 GTexel/s, and FP32 performance is 21.75 TFLOPS.

In Doom, the GPU's role is defining the performance ceiling at higher resolutions. At 4K Ultra, the average frame rate is 57 FPS, which is the lowest measured across all configurations. This indicates that the GPU is the limiting factor when settings are maxed out at 4K. The 8 GB VRAM is sufficient for Doom's textures at all settings presets, as the data shows no anomalous dips that would suggest memory capacity issues. The card's 96 ROPs and 169.9 GPixel/s pixel rate are adequate for the game's Vulkan-based rendering, which leans heavily on fill rate and bandwidth.

The GPU's benchmark scores reinforce its mid-high tier positioning. In 3DMark Steel Nomad DX12, it scores 3478, while Geekbench OpenCL and Vulkan scores are 119,718 and 139,541 respectively. Passmark G3D score is 23,356, and GPU compute is 11,601. The closest rival, the NVIDIA GeForce RTX 5070 Mobile, is only 0.1% ahead in average score, while the AMD Radeon RX 6800 is 0.5% behind. This tight clustering means that in Doom, the RTX 3070 Ti's performance is representative of its class, and the measured FPS numbers reflect that positioning.

Resolution Scaling

The FPS scaling from 1080p to 4K reveals a clear shift in bottleneck behavior across presets. At Low settings, the average FPS drops from 271 at 1080p to 176 at 1440p (a 35% reduction) and further to 95 at 4K (a 65% reduction from 1080p). This steep decline indicates that even at Low settings, the GPU becomes increasingly dominant as resolution rises. The CPU, with its 12 cores and 24 threads boosting to 5.60 GHz, is not the constraining factor at 1080p Low, where 271 FPS is achieved.

At Medium settings, the scaling pattern is similar: 236 FPS at 1080p drops to 153 at 1440p (35% reduction) and then to 83 at 4K (65% reduction from 1080p). The consistency of these percentage drops across Low and Medium suggests that the game's engine scales predictably with resolution when the settings preset does not drastically alter the shading workload. At High settings, the averages are 200 FPS at 1080p, 129 at 1440p (35.5% reduction), and 70 at 4K (65% reduction). Again, the proportional drops are nearly identical.

Ultra settings show the most pronounced scaling impact. At 1080p Ultra, the average is 163 FPS. This falls to 106 at 1440p (35% reduction) and then to 57 at 4K (65% reduction from 1080p). The fact that the percentage reduction from 1080p to 4K is almost exactly 65% across all four settings presets (Low, Medium, High, Ultra) strongly indicates that the GPU is the primary limiter at higher resolutions, regardless of the graphics preset. The CPU is capable of feeding the GPU at 1080p, and as resolution increases, the GPU's rendering workload grows proportionally.

The practical implication is that users targeting 4K should expect to use lower presets to maintain higher frame rates. At 4K Low, the system delivers 95 FPS, which is playable but not high refresh. At 4K Medium, 83 FPS is achieved, and at 4K High, 70 FPS. Only at 4K Ultra does the frame rate dip below 60 FPS, hitting 57 FPS. For 1440p, all presets deliver above 100 FPS, with Low reaching 176 FPS and Ultra still achieving 106 FPS. At 1080p, the system exceeds 160 FPS even at Ultra, making it well-suited for high refresh rate monitors.

Measured FPS Breakdown

At 1080p, the measured average FPS by settings preset is as follows: Low delivers 271 FPS, Medium delivers 236 FPS, High delivers 200 FPS, and Ultra delivers 163 FPS. The Medium preset also has recorded min and max values of 201 FPS and 272 FPS, respectively. The spread from Low to Ultra is 108 FPS, which represents a 40% reduction in frame rate when moving from the lowest to the highest preset. This indicates that the graphical settings have a substantial impact on performance at 1080p, but even the most demanding preset remains far above the 60 FPS threshold.

At 1440p, the averages are: Low at 176 FPS, Medium at 153 FPS, High at 129 FPS, and Ultra at 106 FPS. The Medium preset here shows min and max values of 130 FPS and 176 FPS. The reduction from Low to Ultra is 70 FPS, a 40% drop that mirrors the 1080p scaling. All presets at 1440p remain above 100 FPS, which is excellent for most displays. The consistency of the 40% reduction across resolutions suggests that the settings presets impose a uniform workload increase on the GPU.

At 4K, the averages are: Low at 95 FPS, Medium at 83 FPS, High at 70 FPS, and Ultra at 57 FPS. The Medium preset records min and max values of 70 FPS and 95 FPS. The reduction from Low to Ultra is 38 FPS, a 40% drop that again matches the pattern. Notably, the 4K Medium min FPS of 70 is equal to the 4K High average, showing that the Medium preset has a tighter frame time distribution. The 4K Ultra average of 57 FPS is the only configuration that falls below 60 FPS, and it does so by a slim margin of 3 FPS.

The data across all resolutions shows a consistent 40% performance penalty when moving from Low to Ultra settings. This uniformity indicates that the game's settings presets scale the rendering load in a linear fashion, and the RTX 3070 Ti responds predictably. The min and max values for Medium presets at each resolution provide insight into frame time consistency: at 1080p, the range is 71 FPS (201 to 272), at 1440p it is 46 FPS (130 to 176), and at 4K it is 25 FPS (70 to 95). The narrowing range at higher resolutions indicates that the GPU becomes more consistently utilized as the bottleneck shifts from the CPU to the GPU.

Settings Recommendations

The optimal settings preset depends on the target resolution and refresh rate. For 1080p, the Ultra preset delivers 163 FPS, which is still well above 144 Hz refresh rates. Given that the CPU is not limiting at this resolution, there is no reason to reduce settings below Ultra unless targeting extremely high refresh rates above 163 Hz. For 240 Hz displays, the High preset at 200 FPS or the Low preset at 271 FPS would be necessary, but the visual fidelity loss may not be justified for most users.

At 1440p, the Ultra preset averages 106 FPS, which is suitable for 100 Hz or 120 Hz displays. The High preset at 129 FPS provides a meaningful boost for 144 Hz monitors, and the Medium preset at 153 FPS would accommodate higher refresh rates. The data shows that the reduction from Ultra to High at 1440p costs 23 FPS (a 22% drop in frame rate), while the reduction from High to Medium costs 24 FPS (a 19% drop). The visual differences between these presets are subjective, but the measured FPS suggests that High is the best balance for 1440p gaming, offering 129 FPS while retaining most graphical features.

At 4K, the Ultra preset at 57 FPS is marginally below the 60 FPS target, making it less ideal for smooth gameplay. The High preset at 70 FPS provides a comfortable margin above 60 FPS and is the recommended choice for 4K. The Medium preset at 83 FPS is also viable and would allow for higher refresh rate 4K displays, albeit with reduced visual quality. The Low preset at 95 FPS is the highest performance option, but the visual downgrade may be too significant for a game like Doom, which features detailed environments.

Across all resolutions, the Medium preset consistently delivers the most balanced frame rate with recorded min and max values that show stable performance. The min FPS at 4K Medium is 70, which equals the High preset average, indicating that the Medium preset avoids the frame time spikes that might occur at higher settings. For users who prioritize frame rate consistency over peak visual quality, Medium is a strong choice. For users who prioritize visual quality and have a 60 Hz 4K display, High is the recommended preset, as it exceeds 60 FPS with headroom.

CPU Role

The AMD Ryzen 9 7900X is a 12-core, 24-thread processor based on the Zen 4 architecture (Raphael), manufactured on TSMC's 5 nm process. It has a base clock of 4.70 GHz and a boost clock of 5.60 GHz, with 64 KB of L1 cache per core, 1 MB of L2 cache per core, and 64 MB of shared L3 cache. The CPU supports DDR5 memory on a dual-channel bus with 83.2 GB/s bandwidth, and it is unlocked for overclocking. Its synthetic benchmarks show strong single-thread performance (3DMark single-thread score of 1093, Cinebench R23 single-core of 2016.5) and exceptional multithreaded capability (Cinebench R23 multi-core of 29,300, Geekbench multi-core of 19,267).

In Doom, the CPU's role is to feed the GPU with draw calls and game logic. The measured FPS at 1080p demonstrates that the CPU is not a bottleneck at this resolution. At 1080p Low, the system reaches 271 FPS, and at 1080p Ultra, it still manages 163 FPS. These numbers are far above what most displays can show, indicating that the Ryzen 9 7900X has ample headroom for this game. The 12 cores and 24 threads are more than sufficient for Doom's engine, which was designed for eight-generation consoles and scales well on modern high-core-count processors.

The CPU's nearest rivals in synthetic benchmarks are all within 0.6% of its average score, showing that it sits in a tightly contested performance band. The AMD EPYC 7313P is 0.2% ahead, the Intel Xeon Phi 7290 is 0.3% behind, the Intel Xeon 634 is 0.6% ahead, and the Intel Core i7-14700F is 0.6% behind. This clustering means that the Ryzen 9 7900X's performance in Doom is representative of the top tier of CPUs, and the measured frame rates reflect a system that is not CPU-limited in any tested configuration.

The fact that FPS scaling from 1080p to 4K is nearly identical across all settings presets (a 65% reduction) confirms that the GPU is the limiting factor at higher resolutions. If the CPU were a bottleneck, the scaling from 1080p to 4K would show less severe FPS drops at lower settings, where the CPU has more work relative to the GPU. Instead, the uniform scaling indicates that the Ryzen 9 7900X maintains its performance advantage regardless of resolution, leaving the RTX 3070 Ti as the definitive constraint. This is the expected behavior for a high-end CPU paired with a mid-high tier GPU in a well-optimized game like Doom.
