Doom

The AMD Ryzen 5 7400F and AMD Radeon RX 6800 XT combination delivers a robust performance profile in Doom, with frame rates that scale predictably across resolutions and settings. The data reveals a system that is clearly GPU-bound at higher resolutions, while the CPU’s strong single-thread performance ensures high refresh rate capability at 1080p. This analysis breaks down the measured FPS to understand the balance between processor and graphics card demands.

Resolution Scaling

The measured data shows a clear and consistent drop in average frame rates as resolution increases from 1920x1080 to 3840x2160. At Ultra settings, the average FPS declines from 176 at 1080p to 114 at 1440p, and finally to 62 at 4K. This represents a 35% reduction from 1080p to 1440p, and a further 45% reduction from 1440p to 4K. The scaling pattern indicates that the GPU is the primary limiting factor at higher resolutions, as the workload on the rendering pipeline increases substantially with pixel count.

At High settings, the same trend is visible, with averages of 215, 139, and 75 FPS for 1080p, 1440p, and 4K respectively. The drop from 1080p to 1440p is 76 FPS, while the drop from 1440p to 4K is 64 FPS, showing a slightly steeper decline at the lower resolution step. This suggests that the GPU’s compute resources, including its 4608 shading units and 288 texture mapping units, are being taxed more heavily as the resolution increases.

The Low settings preset shows the least dramatic scaling, with 292 FPS at 1080p, 189 FPS at 1440p, and 102 FPS at 4K. The relative drop from 1080p to 4K is 65%, which is less severe than the 65% drop seen at Ultra settings. This indicates that at Low settings, the system is less constrained by the GPU, allowing the CPU’s capabilities to shine through more prominently. The Ryzen 5 7400F’s boost clock of 4.70 GHz appears sufficient to feed the GPU even at lower resolutions, as the 1080p Low result exceeds 290 FPS.

The scaling behavior implies that for maximum frame rates at 1080p, the CPU is the more critical component, while at 4K, the GPU’s 16 GB of GDDR6 memory and 512.0 GB/s bandwidth become the determining factors. The data shows that the RX 6800 XT’s 128 ROPs are adequate for pixel throughput at 4K, but the average FPS at Ultra 4K (62) is just above the 60 FPS threshold, suggesting that the GPU is nearing its limit with this demanding preset.

How This Combo Ranks

This specific combination of the AMD Ryzen 5 7400F and AMD Radeon RX 6800 XT holds a combo rank of 866 out of 2930 tested combinations in Doom. This places it in the 70th percentile of all tested combos, indicating that it outperforms the majority of systems in this game. The rank is a composite measure that accounts for both CPU and GPU contributions, and the data suggests that the balanced pairing of a Zen 4 processor with a RDNA 2 graphics card yields strong results.

The CPU’s individual percentile ranking is 83rd among all tested CPUs, while the GPU sits in the 85th percentile among all GPUs. These individual rankings are closely aligned, which explains why the combo performs as well as it does. The Ryzen 5 7400F’s nearest rivals show a tight cluster of scores, with the Intel Core i5-14600T just 0.1% ahead, the Intel Core Ultra 7 155H 0.2% ahead, and the AMD Ryzen 7 PRO 6850H 0.2% behind. This indicates that the CPU’s performance is competitive with modern mid-range processors.

For the GPU, the nearest rivals include the NVIDIA RTX A1000 Mobile (1.5% ahead), the Intel Arc A550M (2.5% behind), and the NVIDIA GeForce RTX 5070 Ti (3% behind). The RX 6800 XT’s score of 48477 in the average benchmark places it just above the RTX A1000 Mobile, which is notable given the latter’s mobile form factor. The combination of a high-ranking CPU and GPU results in a system that can handle Doom’s fast-paced action without bottlenecking, as evidenced by the measured frame rates.

The combo rank of 866 out of 2930 means there are 2064 other combinations that perform better, but given the age of the GPU (released in 2020) and the recent CPU (released in 2025), this pairing represents a sensible upgrade path for gamers. The data shows that the combo is well-balanced, as neither component drastically outperforms the other, which is often the cause of suboptimal gaming performance.

GPU Role

The AMD Radeon RX 6800 XT plays a pivotal role in determining the frame rates at higher resolutions. With 16 GB of GDDR6 memory on a 256-bit bus, the GPU provides 512.0 GB/s of memory bandwidth, which is ample for Doom’s texture-heavy environments. The GPU’s base clock of 1825 MHz and boost clock of 2250 MHz, combined with a game clock of 2015 MHz, allow it to sustain high performance under load.

The memory configuration is particularly important at 4K, where the data shows a 75 FPS average at High settings. This suggests that the 16 GB frame buffer is sufficient to hold the game’s assets without causing significant drops, as evidenced by the 4K Medium result of 89 FPS with a minimum of 76 FPS. The GPU’s 72 ray accelerators are not heavily utilized in Doom, as the game does not feature ray tracing, but the RDNA 2 architecture still provides efficient rasterization.

At 1080p Low, the GPU achieves 292 FPS, which is likely close to the CPU’s limit. The GPU’s 4608 shading units are capable of processing the low-complexity scenes quickly, but the frame rate is capped by the processor’s ability to issue draw calls. The RX 6800 XT’s 128 ROPs are not a bottleneck at this resolution, as the pixel fill rate of 288.0 GPixel/s is more than sufficient for 1080p.

The GPU’s FP32 performance of 20.74 TFLOPS is a strong indicator of its compute capability, and the data shows that it translates well into gaming performance. The GPU’s nearest rival, the NVIDIA RTX A1000 Mobile, is only 1.5% ahead in average benchmark score, but the RX 6800 XT’s desktop-class power delivery allows it to sustain higher clocks for longer periods. The GPU’s 300 W TDP and dual-slot cooler are designed for sustained gaming sessions, which is reflected in the consistent frame rates measured across all settings.

Settings Recommendations

Based on the measured FPS data, the Medium preset at 2560x1440 offers the best balance of visual quality and performance. The average FPS of 165 at this setting is well above the 144 Hz refresh rate common on 1440p monitors, and the minimum FPS of 140 ensures smooth gameplay even during intense combat sequences. The jump from Medium to High at 1440p results in a 26 FPS drop to 139, which is noticeable but still playable.

For 4K gaming, the Medium preset is the most viable option, with an average of 89 FPS and a minimum of 76 FPS. This is a significant improvement over the High preset’s 75 FPS average, which lacks a minimum FPS reading but is likely lower. The Ultra preset at 4K drops to 62 FPS, which is just at the threshold of playability and may result in occasional stutter.

At 1080p, the Low preset delivers an impressive 292 FPS, which is ideal for competitive play on high refresh rate monitors. However, the Medium preset at 254 FPS (minimum 216 FPS) provides a better visual experience while still exceeding 240 Hz displays. The High preset at 215 FPS is also excellent, but the Medium preset offers the best price-to-performance in terms of visual fidelity versus frame rate.

The data suggests that for the best overall experience, users should opt for Medium settings at their native resolution. The measured results show that the step from Low to Medium provides a substantial visual improvement with only a 13% frame rate penalty at 1080p, while the step from Medium to High at 4K costs 16% performance for marginal gains. The Ultra preset should be avoided at 4K, as the 62 FPS average is too close to the 60 FPS minimum for comfort.

This consistency suggests that the Medium preset avoids the occasional spikes that could occur with higher settings.

CPU Role

The AMD Ryzen 5 7400F provides the computational foundation for this combo, and its impact is most visible at lower resolutions. With 6 cores and 12 threads based on the Zen 4 architecture, the CPU has a base clock of 3.70 GHz and a boost clock of 4.70 GHz. The 32 MB of shared L3 cache is beneficial for Doom’s level streaming, and the 83.2 GB/s memory bandwidth from dual-channel DDR5 support ensures that the GPU is fed with data quickly.

The CPU’s benchmark scores are telling: a Cinebench R23 multi-core score of 21765 and a single-core score of 3072. The single-core performance is particularly important for Doom, as the game is known to favor high IPC over many cores. The PassMark single-thread score of 3689 places it in the 83rd percentile of all CPUs, which is reflected in the 1080p Low result of 292 FPS.

The CPU’s nearest rivals show a narrow performance gap, with the Intel Core i5-14600T being 0.1% ahead and the AMD Ryzen 7 PRO 6850H being 0.2% behind. This indicates that the 7400F is well-positioned in the mid-range market. The CPU’s 65 W TDP is remarkably low for the performance it delivers, which confirms the efficiency of the 5 nm process node from TSMC.

At 1080p, the CPU’s role is critical. The difference between Low and Ultra settings at 1080p is 116 FPS, but this is primarily due to GPU load. The CPU’s ability to maintain high frame rates is shown by the fact that at 1080p Low, the system achieves 292 FPS, which is likely near the CPU’s maximum draw call throughput. The boost clock of 4.70 GHz ensures that single-threaded performance is maximized, and the 6 cores are sufficient for Doom’s multi-threaded rendering tasks.

The data shows that the CPU does not bottleneck the GPU until frame rates exceed 250 FPS, which is only achieved at 1080p Low. At all other settings, the GPU is the limiting factor, as evidenced by the consistent frame rate scaling with resolution. The CPU’s 12 threads are enough to handle the game’s background tasks without interfering with the main rendering thread, and the 32 MB L3 cache helps reduce memory latency.
