Doom

Resolution Scaling

The measured frame rates across the three resolutions paint a clear picture of how this combination handles Doom's engine. At 1920x1080 with Low settings, the system produces 365.3 FPS, which drops to 236.8 FPS at 2560x1440 and further to 128.6 FPS at 3840x2160. This scaling pattern—a 35% reduction from 1080p to 1440p and a 65% reduction from 1080p to 4K at Low settings—indicates that the GPU becomes progressively more dominant as pixel count rises.

The High preset tells a similar story: 271.4 FPS at 1080p, 175.5 FPS at 1440p, and 94.1 FPS at 4K. The drop from 1080p to 1440p represents a 35% decrease, while the 4K figure sits 65% below the 1080p result. These consistent percentage drops across presets suggest the scaling is resolution-driven rather than settings-driven, which is typical for a game like Doom that relies heavily on GPU throughput at higher resolutions.

At Ultra settings, the frame rate curve steepens: 224.7 FPS at 1080p falls to 140.4 FPS at 1440p, then 79.9 FPS at 4K. The 4K result is 64% lower than the 1080p figure, nearly identical to the scaling observed at Low and High. This uniformity indicates that the limiting component shifts decisively toward the GPU as resolution increases, regardless of which quality preset is active.

The data also reveals that the 1440p to 4K transition is the most punishing. At High settings, moving from 1440p to 4K costs 81.4 FPS (from 175.5 to 94.1), while the 1080p to 1440p step costs 95.9 FPS (from 271.4 to 175.5). These are comparable absolute drops, but the 4K result falls below the 100 FPS threshold, which may matter for high-refresh-rate displays. The 1080p results, by contrast, remain well above 200 FPS at every preset, suggesting the CPU and GPU combination is never the bottleneck at that resolution.

GPU Role

The NVIDIA GeForce RTX 4070 Ti pairs a 2310 MHz base clock with a 2610 MHz boost clock, and its 12 GB of GDDR6X memory runs at 1313 MHz (21 Gbps effective) across a 192-bit bus. The resulting 504.2 GB/s of memory bandwidth is a key factor in Doom's texture-heavy scenes, especially at 4K where the engine demands rapid data movement. The GPU's 7680 shading units and 240 TMUs handle the game's geometry and texture work, while 80 ROPs manage the final pixel output.

Benchmark data places this GPU in the 85th percentile among all GPUs, with an average benchmark score of 44900. Its nearest rival, the NVIDIA GeForce RTX 5090 Mobile, scores 45152, a delta of -0.6%, meaning the RTX 4070 Ti is essentially performance-equivalent to that mobile part. The AMD Radeon Pro 580 trails by 1.6% with a score of 44195, while the Intel Arc A730M leads by 1.5% at 45592. These margins are small, indicating the RTX 4070 Ti sits in a tightly contested performance band.

In Doom specifically, the GPU's role becomes apparent when examining the FPS deltas between presets at the same resolution. At 4K, Low produces 128.6 FPS, Medium 114.5 FPS, High 94.1 FPS, and Ultra 79.9 FPS—a 48.7 FPS spread from lowest to highest quality. At 1080p, that spread widens to 140.6 FPS (365.3 Low versus 224.7 Ultra), showing that the GPU has more headroom at lower resolutions. The 60 RT cores and 240 tensor cores, while not directly exercised by Doom's traditional rasterization path, contribute to the card's overall compute capabilities that the game's engine can leverage for post-processing effects.

The GPU's 208.8 GPixel/s pixel rate and 626.4 GTexel/s texture rate provide the raw throughput needed to sustain the measured frame rates. At 4K Ultra, the 79.9 FPS result demonstrates that even this high-end card is pushed hard by maxed-out settings, though it remains playable. The 285 W TDP and 600 W suggested PSU indicate the power envelope required to sustain these clocks under load.

Settings Recommendations

The measured data offers a straightforward hierarchy for Doom on this hardware. At 1920x1080, every preset delivers well above 200 FPS, with Low at 365.3, Medium at 319.5, High at 271.4, and Ultra at 224.7. The Ultra preset's 224.7 FPS is 1.6x higher than the 4K High result, making it the best choice for competitive play on high-refresh-rate monitors. The gap between High and Ultra at 1080p is 46.7 FPS, which may be worth sacrificing for the visual fidelity gains that Ultra brings.

At 2560x1440, the Medium preset's 209.2 FPS stands out as the sweet spot. It exceeds the High preset's 175.5 FPS by 33.7 FPS while remaining above the 200 FPS mark. Ultra at 140.4 FPS is still playable but drops below the 144 Hz refresh rate that many 1440p monitors offer. Low at 236.8 FPS is the maximum achievable, but the visual compromise is substantial for only a 27.6 FPS gain over Medium.

For 3840x2160, the choice is more constrained. High at 94.1 FPS and Medium at 114.5 FPS are the only presets that clear the 60 FPS floor comfortably. Ultra at 79.9 FPS is technically playable but sits close to the boundary where frame pacing becomes noticeable. Low at 128.6 FPS offers the best smoothness, but the visual downgrade at 4K is more apparent than at lower resolutions. The data suggests Medium is the optimal 4K preset: it delivers 114.5 FPS, which is 35.4% higher than Ultra and only 14.1 FPS below Low, while retaining substantially better image quality.

The overall recommendation based on the measured rows is to use Ultra at 1080p, Medium at 1440p, and Medium at 4K. This combination maximizes visual quality while keeping frame rates above 100 FPS at every resolution.

Q: Is the CPU or GPU more likely to bottleneck at 1080p?

A: The data shows 1080p frame rates above 200 FPS at every preset, with Low reaching 365.3 FPS. These high values suggest the GPU is doing the heavy lifting, but the Ryzen 5 7600X's 6 cores and 12 threads with a 5.30 GHz boost clock provide enough single-thread performance to avoid becoming the primary limiter at this resolution.

CPU Role

The AMD Ryzen 5 7600X contributes to Doom's performance through its 6 cores and 12 threads, running at a base clock of 4.70 GHz and boosting to 5.30 GHz. This Zen 4 architecture, built on a 5 nm process at TSMC, delivers strong single-thread performance that matters for Doom's tightly optimized engine. The 32 MB of shared L3 cache and 1 MB per-core L2 cache help keep frequently accessed game data close to the cores.

Synthetic benchmarks show the CPU's capabilities: Cinebench R23 multicore scores 24128, while single-core scores 3406. Geekbench results are 12905 multicore and 2892 single-core. The 3DMark tests reveal scaling from 1060 single-thread to 6879 at 16 threads, indicating efficient multi-threading. The PassMark single-thread score of 4135 and multithread score of 28390 confirm balanced performance.

The CPU's 83rd percentile ranking among all CPUs places it near the AMD Ryzen 7 PRO 6850U (26262, 0% delta) and AMD Ryzen 7 5700X (26214, 0.2% higher). These rivals are all within 0.2% of the 7600X in average benchmark score, suggesting that CPU-bound scenarios in Doom would show negligible differences between these processors.

In Doom specifically, the CPU's role is most evident at 1080p where frame rates are highest. The 365.3 FPS Low result and 271.4 FPS High result require rapid draw-call processing and physics updates, which the 7600X's 5.30 GHz boost clock handles effectively. The 12 threads provide headroom for background tasks and streaming, though Doom's engine is not heavily multi-threaded compared to modern titles. The 83.2 GB/s memory bandwidth from dual-channel DDR5 support ensures the CPU can feed data to the GPU without starving it, particularly at high frame rates.

The 105 W TDP and unlocked multiplier indicate this is a performance-focused part, and the 6,570 million transistors on a 71 mm² die demonstrate efficient design. For Doom, the CPU never appears to be the limiting factor based on the measured FPS: even at 1080p Ultra with 224.7 FPS, the GPU's 40.09 TFLOPS FP32 throughput is sufficient to maintain high output. The CPU's single-thread performance, as evidenced by the 3406 Cinebench R23 single-core score, aligns well with Doom's engine architecture that favors high clock speeds over core counts.
