Doom

The AMD Ryzen 7 5700X3D paired with the AMD Radeon RX 6700 XT delivers a robust experience in Doom, with the data showing a clear hierarchy where frame rates scale predictably with both resolution and graphical preset. The measured results indicate this combination is well-balanced for high-refresh-rate 1080p and solid 1440p gameplay, while 4K remains achievable with settings adjustments.

Resolution Scaling

The transition from 1080p to 4K reveals a significant performance cost, with average frame rates dropping by roughly 55-60% depending on the preset. At 1080p Low, the system produces 233.1 FPS, but at 4K Low, that figure falls to 84 FPS. This steep decline suggests that the GPU becomes the limiting factor as pixel count increases, which is typical for a game like Doom that relies heavily on fill rate and memory bandwidth.

Looking at the High preset, the scaling pattern is even more telling. At 1080p, the average is 168.7 FPS, dropping to 110.1 FPS at 1440p, and then to 59.6 FPS at 4K. The gap between 1440p and 4K is a 46% reduction, which is substantial but still leaves the game playable. The Ultra preset shows the most strain, going from 137.7 FPS at 1080p down to 89.8 FPS at 1440p and finally 52.2 FPS at 4K. This indicates that 4K Ultra is pushing the RX 6700 XT to its limits, with the average barely above the 60 FPS threshold.

The data suggests that the CPU is not the bottleneck at lower resolutions. At 1080p Low, the system achieves 233.1 FPS, which is well beyond what most displays can show, and the Ryzen 7 5700X3D with its 8 cores and 16 threads provides ample headroom. The bottleneck shifts to the GPU as resolution increases, which is the expected behavior for a modern FPS title. The measured results show that the 5700X3D can feed the RX 6700 XT effectively even at high frame rates, as evidenced by the 168.7 FPS average at 1080p High without any signs of CPU limitation.

GPU Role

The AMD Radeon RX 6700 XT is built on the RDNA 2.0 architecture with 12 GB of GDDR6 memory on a 192-bit bus, providing 384.0 GB/s of bandwidth. The card's base clock is 2321 MHz, with a game clock of 2424 MHz and a boost clock of 2581 MHz. These specifications translate directly to the measured performance in Doom, where the GPU's memory subsystem and shading units are heavily utilized.

The 12 GB VRAM capacity is sufficient for this game, even at 4K, as the data shows playable frame rates at all presets. The Ultra preset at 4K averages 52.2 FPS, which indicates the card is not running out of memory but rather hitting compute limits. The 2560 shading units and 64 ROPs are likely the primary constraints at higher resolutions, as the pixel rate of 165.2 GPixel/s becomes a limiting factor.

The GPU's position in the benchmark database is solid, sitting at the 77th percentile of all GPUs. Its nearest rivals include the AMD Radeon RX 6800, which scores 0.7% higher, and the AMD Radeon HD 7950, which scores 1% higher. The RX 6700 XT's average benchmark score of 33721 places it in a competitive tier, and the Doom results align with this positioning. The card's 13.21 TFLOPS of FP32 compute power is well-suited for the id Tech engine, which has historically favored AMD hardware.

The fact that the 4K High preset achieves 59.6 FPS while the 4K Low preset reaches 84 FPS shows a 41% performance uplift from lowering settings. This indicates that the GPU is sensitive to shader complexity and texture quality, with the memory bandwidth of 384.0 GB/s being a key factor in maintaining consistent frame delivery.

Settings Recommendations

The measured data provides clear guidance on the optimal settings for this hardware. For 1080p users, the High preset at 168.7 FPS is the recommended starting point, as it offers a substantial visual upgrade over Medium (201 FPS) while still maintaining excellent frame rates. The Ultra preset at 137.7 FPS is viable for those with 144Hz displays, but the 18% performance cost may not justify the visual gains.

At 1440p, the High preset at 110.1 FPS is the best choice for a 100Hz or 120Hz monitor. The Medium preset at 128.8 FPS is also excellent if higher frame rates are preferred, while the Ultra preset at 89.8 FPS remains playable but requires a 90Hz or lower refresh rate display. The Low preset at 146.6 FPS is only recommended for competitive play where maximum frame rates are paramount.

For 4K, the Medium preset at 69 FPS is the sensible choice, as it provides a smoother experience than High (59.6 FPS) while maintaining decent visual fidelity. The Low preset at 84 FPS is the best option for those who prioritize frame rate over image quality. The Ultra preset at 52.2 FPS is not recommended for a consistent experience, as the frame rate dips below the 60 FPS threshold.

The data clearly shows diminishing returns from the Ultra preset across all resolutions. The performance gap between Medium and High is smaller than the gap between High and Ultra, making High the most efficient preset in terms of performance per visual quality. Lowering settings from Ultra to High yields a 22% improvement at 1080p, a 22.6% improvement at 1440p, and a 14.2% improvement at 4K.

The High preset averages 59.6 FPS, a 13.6% drop from Medium. The Ultra preset averages 52.2 FPS, a 12.4% drop from High. The scaling from 1440p to 4K results in a 42-43% reduction across all presets, which is consistent with the pixel count increase of 2.25x.

The data shows that the performance gap between presets narrows as resolution increases. At 1080p, the difference between Low and Ultra is 95.4 FPS (233.1 vs 137.7). At 1440p, this gap shrinks to 56.8 FPS (146.6 vs 89.8). At 4K, it narrows further to 31.8 FPS (84 vs 52.2). This pattern suggests that the GPU's compute resources become the dominant factor at higher resolutions, while settings have less relative impact.

CPU Role

The AMD Ryzen 7 5700X3D is a 5000 series processor based on the Zen 3 architecture, featuring 8 cores and 16 threads. Its base clock of 3.00 GHz and boost clock of 4.10 GHz, combined with 96 MB of shared L3 cache, make it exceptionally well-suited for gaming workloads. The CPU's benchmark scores reflect this, with a Cinebench R23 multicore score of 22366 and a single-core score of 3157.

In Doom, the CPU's role is primarily to feed the GPU with draw calls and physics calculations. The data indicates that the 5700X3D is more than capable of keeping up with the RX 6700 XT, as evidenced by the high frame rates at 1080p. The 3DMark 16-thread score of 6764 and the Passmark multithread score of 26318 show strong multi-threaded performance, which is beneficial for the id Tech engine's task scheduling.

The CPU sits at the 82nd percentile of all CPUs, with an average benchmark score of 24673. Its nearest rivals include the Intel Core i7-1360P, which scores 0.2% higher, and the AMD Ryzen 5 7600X3D, which scores 0.3% higher. This places the 5700X3D in a highly competitive position, especially considering its 8-core/16-thread configuration and the substantial L3 cache.

The lack of any frame rate plateau in the 1080p results suggests that the CPU is not the bottleneck in this system. Even at the highest settings, the 1080p Ultra average of 137.7 FPS is well within the CPU's capability. The 4K results further confirm this, as the performance drop is entirely attributable to the GPU's pixel processing limits rather than any CPU constraint. The 5700X3D's 105W TDP and 7nm process node from TSMC allow for sustained boost clocks, ensuring consistent performance across extended gaming sessions.
