Doom

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

The AMD Ryzen 7 7700 is an 8-core, 16-thread processor built on the Zen 4 Raphael architecture, using a 5 nm process at TSMC. Its base clock is 3.80 GHz with a boost clock of 5.30 GHz, and it carries 32 MB of shared L3 cache alongside 1 MB of L2 per core. The chip's single-thread performance is strong, as shown by its 3DMark single-thread score of 1049, and its multi-threaded capability is reflected in a Cinebench R23 multi-core score of 29302.

For a fast-paced FPS like Doom, single-thread speed often dictates frame pacing, and the Ryzen 7 7700 delivers. Its boost clock of 5.30 GHz helps maintain high minimum frame rates even when the action gets chaotic. The processor's 16 threads matter less in this title, as the game's engine is not heavily parallelized; instead, the high per-core throughput is what keeps the frame rate from collapsing. In the benchmark data, the CPU's percentile versus all CPUs is 91, placing it in the top tier. Its nearest rival, the AMD Ryzen 9 7940H, scores 40431 in average benchmarks, a delta of only 0.1% — a statistical tie. The Intel Core i9-13905H is 0.6% faster, while the AMD Ryzen AI 9 365 is 0.5% slower, showing that the 7700 sits in a tightly contested performance band.

At 1080p with Low settings, the measured average FPS reaches 274.1, which is far beyond the refresh rate of most displays, indicating that the CPU is not the limiting factor even at high frame rates. The processor's ability to feed the GPU quickly is evident in the 3DMark 16-thread score of 8484, but it's the 2-thread score of 2043 that hints at how well it handles lightly threaded game logic. The L3 cache of 32 MB shared across 8 cores helps with game data locality, reducing memory latency that could otherwise stall frame rendering. Overall, the Ryzen 7 7700 provides ample headroom for Doom's requirements, ensuring that the GPU becomes the bottleneck in most scenarios.

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

The NVIDIA GeForce RTX 3070 Ti is built on the Ampere architecture with the GA104 chip, manufactured on Samsung's 8 nm process. It has 8 GB of GDDR6X memory on a 256-bit bus, delivering 608.3 GB/s of bandwidth. The GPU's base clock is 1575 MHz with a boost clock of 1770 MHz, and it sports 6144 shading units, 192 TMUs, and 96 ROPs. Its FP32 compute is rated at 21.75 TFLOPS, and it includes 48 RT cores and 192 tensor cores for ray tracing and DLSS workloads.

In Doom, the 8 GB VRAM capacity is sufficient for the game's demands at all tested settings, including Ultra at 4K. The memory bandwidth of 608.3 GB/s ensures that texture streaming and high-resolution assets do not cause stutter. The benchmark data shows that the GPU's percentile versus all GPUs is 74, meaning it outperforms the majority of graphics cards but sits below the top tier. Its nearest rivals include the AMD Radeon RX 6700, which is 0.8% faster in average score, and the NVIDIA Quadro M5000, which is 0.9% faster — all within a narrow margin.

The GPU's performance in Doom scales predictably with resolution. At 1080p with Ultra settings, the average FPS is 167.1, which drops to 103.6 at 1440p and 58 at 4K. This scaling shows that the RTX 3070 Ti is the primary limiter at higher resolutions, as the CPU has more than enough power to keep up. The 8 GB VRAM does not appear to be a constraint, as the frame rate drop from Ultra to High at 4K is 14.6 FPS (from 58 to 72.6), which is more likely due to shading complexity rather than memory capacity. The GPU's boost clock of 1770 MHz provides consistent performance, and its 96 ROPs handle pixel fill rate well at 169.9 GPixel/s.

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

The measured FPS data reveals a clear trend: performance scales with resolution, and the GPU becomes the bottleneck as pixel count increases. At 1080p with Low settings, the average FPS is 274.1, which is exceptionally high and suggests the CPU is capable of pushing frames well beyond typical display refresh rates. Moving to 1440p Low, the average drops to 179.1, a reduction of 95 FPS or roughly 35%. At 4K Low, the average is 93.5, another significant drop of 85.6 FPS from 1440p.

The pattern holds across all settings. For High settings, the FPS goes from 199 at 1080p to 130 at 1440p (a 69 FPS drop) and then to 72.6 at 4K (a 57.4 FPS drop). Ultra settings show the most dramatic decline: 167.1 at 1080p, 103.6 at 1440p, and 58 at 4K. These numbers indicate that the RTX 3070 Ti is the limiting component at 4K, as the CPU's high single-thread performance is not the constraint. The fact that the 1080p Low result of 274.1 FPS is nearly double the 4K Low result of 93.5 FPS confirms that the GPU's pixel throughput is the bottleneck at higher resolutions.

The resolution scaling also shows diminishing returns at 4K. The gap between Low and Ultra at 4K is 35.5 FPS (from 93.5 to 58), while at 1080p the gap is 107 FPS (from 274.1 to 167.1). This suggests that at 4K, the GPU is so heavily loaded that the difference between settings has less impact on absolute FPS, whereas at 1080p, the CPU can feed frames fast enough for settings to matter more. For a game like Doom, which is known for fast movement, the 4K Ultra result of 58 FPS is borderline for competitive play, while 1080p and 1440p offer smoother experiences.

Settings Recommendations

For the best balance of visual quality and performance, High settings at 2560x1440 are the optimal choice. The measured average FPS of 130 at this configuration is well above the 60 FPS threshold and provides smooth gameplay for a fast FPS title. The jump to Ultra at 1440p reduces FPS to 103.6, which is still playable but offers diminishing visual returns for the performance cost.

At 1920x1080, Ultra settings are viable with an average of 167.1 FPS, making this the best choice for players with high refresh rate monitors who want maximum visual fidelity. The 1080p Low setting at 274.1 FPS is excessive for most displays and offers no practical benefit over Medium or High.

At 3840x2160, High settings are recommended, as they deliver 72.6 FPS, which is above the 60 FPS target. Ultra at 4K drops to 58 FPS, which may cause noticeable stutter in fast-paced action. Medium at 4K yields 86.1 FPS, but the visual quality loss is significant compared to High. For players prioritizing frame rate over visuals at 4K, Medium is a better choice than Low, as the 7.4 FPS gain from Low to Medium is minimal, while the visual improvement is substantial.
