Doom

The AMD Ryzen 5 8400F and AMD Radeon RX 7700 combination delivers a remarkably smooth experience in Doom across all tested configurations. The benchmark data shows this pairing is capable of high refresh rate gameplay at 1080p and 1440p, while still maintaining playable frame rates at 4K. The measured results indicate a system that scales predictably with resolution and settings, making it a versatile option for this title.

Settings Recommendations

The measured FPS data shows a clear hierarchy across the four available presets. For players targeting the highest refresh rates on standard 1080p displays, the Low preset delivers an average of 241 FPS, which is the peak performance measured in this dataset. However, the Medium preset at 210 FPS average represents a more balanced choice, offering a substantial improvement over Low while only sacrificing 31 FPS on average. The Medium preset also provides the only complete min/max data at this resolution, with a minimum of 179 FPS and maximum of 242 FPS, indicating consistent frame pacing.

At 1440p, the High preset achieves an average of 115 FPS, which is an excellent target for 120Hz displays. The Medium preset reaches 136 FPS average, with a minimum of 116 FPS and maximum of 156 FPS. This makes Medium the recommended choice for 1440p gaming, as it provides a comfortable margin above 60 FPS even in demanding scenes while delivering the headroom needed for smooth gameplay on high refresh rate monitors.

For 4K resolution, the situation changes significantly. The High preset manages an average of 62 FPS, which is just above the 60 FPS threshold commonly considered the minimum for smooth gameplay. The Medium preset achieves 74 FPS average with a minimum of 63 FPS and maximum of 85 FPS, making it the best option for 4K. The Ultra preset drops to 51 FPS average, which falls below the 60 FPS target and may result in noticeable judder. The data suggests that Medium at 4K provides the optimal balance between visual quality and performance, as it maintains a minimum above 60 FPS while offering better visual fidelity than Low.

GPU Role

The AMD Radeon RX 7700 features 16 GB of GDDR6 memory on a 256-bit bus, providing 624.1 GB/s of memory bandwidth. This substantial memory configuration proves advantageous in Doom, as the game's texture-heavy environments benefit from the available VRAM capacity. The GPU's clock speeds are notable: a base clock of 1900 MHz, a game clock of 2041 MHz, and a boost clock of 2459 MHz. The boost clock behavior is evident in the measured results, as the GPU maintains higher frame rates at lower settings, suggesting the ability to sustain elevated clocks under lighter loads.

The GPU's 2560 shading units and 96 ROPs contribute to its pixel throughput of 236.1 GPixel/s. This pixel rate is directly relevant to the 4K results, where the GPU processes 8.3 million pixels per frame at 3840x2160. The measured 4K performance shows a clear scaling pattern: from 85 FPS at Low to 51 FPS at Ultra, representing a 40% performance drop when moving from the least to most demanding preset. This scaling indicates that the GPU becomes the primary limiting factor at 4K, as the visual complexity of Ultra settings overwhelms the available processing power.

The GPU's FP32 compute of 25.18 TFLOPS provides ample raw processing capability for Doom's rendering workload. The RDNA 3.0 architecture with 40 ray tracing cores suggests future-proofing potential, though the current data shows the game performs well without relying heavily on these features. The 16 GB VRAM capacity ensures that even at 4K Ultra settings, memory capacity is unlikely to become a bottleneck, allowing the GPU to focus on compute and pixel throughput.

Resolution Scaling

The measured FPS data reveals a consistent pattern of performance degradation as resolution increases from 1080p to 4K. At Low settings, the system delivers 241 FPS at 1920x1080, which drops to 156 FPS at 2560x1440, and further to 85 FPS at 3840x2160. This represents a 35% reduction from 1080p to 1440p, and a subsequent 45% reduction from 1440p to 4K. The cumulative effect is a 65% performance drop from 1080p to 4K.

The scaling pattern at High settings follows a similar trajectory: 178 FPS at 1080p, 115 FPS at 1440p, and 62 FPS at 4K. The percentage drops are 35% and 46% respectively, showing that the GPU's performance scales nearly linearly with pixel count. This linear scaling is characteristic of a GPU-bound scenario, where the rendering workload increases proportionally with resolution.

The Medium settings data provides additional insight through the min/max FPS ranges. At 1080p, the range spans from 179 to 242 FPS, a 63 FPS spread. At 1440p, the range narrows to 116 to 156 FPS, a 40 FPS spread. At 4K, the range tightens further to 63 to 85 FPS, a 22 FPS spread. This narrowing range at higher resolutions indicates that the GPU is becoming more consistently saturated, reducing frame time variance as the workload approaches the GPU's maximum capacity.

The scaling behavior strongly suggests that the GPU is the limiting component across all resolutions. The CPU's 6 cores and 12 threads provide sufficient processing power to feed the GPU even at 1080p, where 241 FPS requires a high frame rate to maintain CPU-bound performance. The consistent 2.8-2.9x performance difference between 1080p and 4K across settings indicates that the system's performance is dictated by the GPU's pixel processing capabilities rather than any CPU bottleneck.

This power efficiency allows the CPU to maintain high clock speeds without thermal throttling, which is beneficial for gaming workloads that rely on sustained single-thread performance.

The CPU's cache hierarchy includes 64 KB of L1 cache per core, 1 MB of L2 cache per core, and 16 MB of shared L3 cache. This cache configuration is well-suited for Doom's gameplay, where frequently accessed data benefits from the large L3 cache. The dual-channel DDR5 memory support provides 83.2 GB/s of memory bandwidth, which is sufficient to prevent memory bandwidth from becoming a bottleneck in this title.

Benchmark results show the CPU's capabilities across various workloads. The Cinebench R23 multi-core score of 20851 demonstrates strong multi-threaded performance, while the single-core score of 2943 indicates solid single-thread capability. The 3DMark scores provide additional context: 951 single-thread, 1874 for 2 threads, 3563 for 4 threads, and 6091 for 16 threads. The scaling from 2 to 4 threads shows a 90% improvement, and from 4 to 8 threads a 48% improvement, indicating good multi-threading efficiency.

In Doom specifically, the CPU's performance is more than adequate given the measured frame rates. At 1080p Low settings, the system reaches 241 FPS, which approaches the practical limits of most displays. The CPU's percentile ranking of 77% among all CPUs suggests it is well above average, and its nearest rival, the AMD Ryzen 5 7500F, performs within 0.2% in average benchmark scores. This close performance parity confirms that the 8400F is a competitive gaming processor.
