Doom

The AMD Ryzen 7 7700 and AMD Radeon RX 7600 combination delivers a compelling 1080p and 1440p experience in Doom, but the data clearly indicates that the GPU is the primary bottleneck as resolution climbs. At 1080p, the combo is firmly in high-refresh territory across all settings, while 4K Ultra falls below the playability threshold. The benchmark results show a system that is well-balanced for mainstream gaming but not designed for maximum fidelity at 4K.

Resolution Scaling

The measured FPS data reveals a predictable and steep performance decline as resolution increases, which is a classic sign of a GPU-bound workload at higher pixel counts. Moving from 1920x1080 to 2560x1440 at High settings, the average frame rate drops from 141.6 FPS to 90 FPS, a reduction of 51.6 FPS or approximately 36%. This scaling is substantial, indicating that the RX 7600's rendering throughput is the limiting factor at 1440p.

The transition from 2560x1440 to 3840x2160 at High settings is even more punishing. The average FPS falls from 90 to 50.4, a 44% performance loss. This steep decline at 4K is expected for a GPU with 8 GB of memory and a 128-bit bus; the pixel fill rate and memory bandwidth of 288.0 GB/s are simply insufficient to maintain high frame rates at that resolution. The data shows the GPU is working progressively harder, and the frame rate curve confirms that the RX 7600 is the dominant constraint at 4K.

At the Low preset, the scaling pattern is similar but starts from a higher baseline. The 1080p Low average of 191.6 FPS drops to 126.9 FPS at 1440p, then to 66.7 FPS at 4K. This indicates that even with reduced graphical load, the 4K resolution is too demanding for the GPU. The difference between the 1080p Low and 4K Low results is 124.9 FPS, a 65% drop. This suggests that the game engine's rendering load at 4K, regardless of settings, exceeds the RX 7600's capabilities. The limiting component is unequivocally the GPU; the CPU's 8 cores and 16 threads are not the constraining factor here, as evidenced by the fact that frame rates scale downwards with resolution, which is a signature of GPU limitation.

Settings Recommendations

The optimal experience from the data is the Medium preset at 1920x1080, offering a 170.3 FPS average. This provides a smooth, high-refresh experience while maintaining a visual quality step above Low. The High preset at 1080p is also excellent, with 141.6 FPS, but the 28.7 FPS gain from High to Medium is significant for fast-paced FPS gameplay. For players prioritizing maximum fluidity, Low at 1080p yields 191.6 FPS, but the visual compromise is often not worth the frame rate headroom.

At 2560x1440, the Medium preset delivers 111.7 FPS, which is the sweet spot for this resolution. This is comfortably above the 60 FPS threshold and provides a good balance between visual fidelity and performance. The High preset at 1440p (90 FPS) is playable, but the 21.7 FPS drop to Medium suggests that the GPU is struggling with the higher-quality textures and effects. The Ultra preset at 1440p (74.9 FPS) is on the edge of high-refresh territory, but the 36.8 FPS penalty compared to Medium makes it a less compelling choice.

At 3840x2160, the data is less forgiving. The Medium preset (62 FPS) is the only setting that achieves a playable frame rate. Low (66.7 FPS) is marginally faster, but High (50.4 FPS) and Ultra (39 FPS) are below the smoothness threshold for an FPS title. The recommended approach for 4K is to use Medium or Low, but the benchmark data suggests that 1440p is the intended resolution for this combo. The Ultra preset at 1080p (114.3 FPS) is a viable option for those who want maximum visual quality, but it sacrifices significant performance compared to Medium.

GPU Role

The AMD Radeon RX 7600's specifications directly correlate with the measured performance. Its 8 GB of GDDR6 memory on a 128-bit bus, yielding 288.0 GB/s of bandwidth, is sufficient for 1080p and 1440p, but it becomes a limiting factor at 4K. The Ultra preset, which typically uses more memory and higher-resolution textures, shows the most significant performance drop at 4K, falling to 39 FPS. This is a clear indication that the memory subsystem is overwhelmed at that resolution.

The GPU's clock speeds are high, with a base clock of 1720 MHz and a boost clock of 2655 MHz, which contributes to its strong 1080p performance. The game clock of 2250 MHz is representative of sustained gaming workloads. The GPU's FP32 compute power is listed at 21.75 TFLOPS, which is a theoretical figure that aligns with the 2048 shading units. The benchmark results show that the GPU is capable of 191.6 FPS at 1080p Low, demonstrating that it can leverage its compute and clock speeds effectively when not bottlenecked by memory bandwidth.

The RX 7600's percentile ranking of 63rd among all GPUs places it in the mid-range tier. Its nearest rival, the AMD Radeon RX 7600 XT, has an average benchmark score that is 0.6% higher, showing that the 7600 is very close to its immediate superior in overall performance. The data suggests that the GPU's performance is well-optimized for the Doom engine, as the frame rates are consistently high at 1080p and 1440p, but the 4K results are hampered by the memory architecture. The 128-bit bus width is a key bottleneck at higher resolutions, as it limits the amount of data that can be transferred per clock cycle.

CPU Role

The AMD Ryzen 7 7700 provides a robust foundation for this gaming system. With 8 cores and 16 threads, it offers ample processing power for the Doom engine. Its base clock of 3.80 GHz and boost clock of 5.30 GHz are high, and its 3DMark single-thread score of 1049 and Cinebench R23 single-core score of 4136 indicate excellent single-threaded performance, which is crucial for game logic and physics. The CPU's 32 MB of shared L3 cache is another asset for gaming, as it helps reduce memory latency.

The benchmark data suggests that the CPU is not the limiting factor in this combination. The frame rates scale directly with resolution, which is a clear indicator of a GPU bottleneck. At 1080p, the CPU is able to feed the GPU sufficiently to reach 191.6 FPS on Low settings. The fact that the average FPS drops by a similar percentage across all settings when moving to 1440p and 4K confirms that the CPU is not being saturated. The CPU's multi-threaded capabilities, evidenced by a Cinebench R23 multi-core score of 29302, are more than adequate for this game.

The 65W TDP of the CPU is low, which is good for system thermals, but it does not mean performance is compromised. The high boost clock of 5.30 GHz ensures that the CPU can respond quickly to demanding gaming workloads. The CPU's memory bandwidth of 83.2 GB/s for DDR5 is sufficient to keep the GPU fed with data, as the GPU's frame rates are not artificially limited by memory throughput. The data indicates that the CPU is a high-performance component that pairs well with the RX 7600, providing a stable and fast platform for gaming.
