Doom

The AMD Ryzen 5 7600 and AMD Radeon RX 6600 XT pairing delivers a compelling but uneven experience in Doom, with performance scaling that clearly exposes the GPU as the primary bottleneck at higher resolutions. The benchmark data reveals a system that can push past 180 FPS at 1080p on Low settings but falls below 50 FPS at 4K on Ultra, indicating a significant shift in the limiting component as resolution increases. This analysis examines the measured frame rates, component roles, and ranking data to provide a clear picture of what this combination offers.

Resolution Scaling

The measured FPS data shows a dramatic and consistent drop as resolution climbs from 1920x1080 to 3840x2160, a pattern that strongly implicates the GPU as the limiting factor. At High settings, the average frame rate falls from 139.1 FPS at 1080p to 93.1 FPS at 1440p, a reduction of 46 FPS, and then plunges to 49.1 FPS at 4K, representing a 64.7% decrease from the 1080p figure. This steep decline is characteristic of a system where the Radeon RX 6600 XT’s rendering throughput, rather than the CPU’s processing power, dictates the upper ceiling.

The scaling pattern becomes even more telling when examining the Low settings row. Here, the average FPS moves from 189.4 at 1080p down to 122.8 at 1440p and then to 69.3 at 4K. The fact that even at the lowest graphical preset, 4K performance drops below 70 FPS suggests that the GPU is saturated by the sheer pixel count, regardless of the reduced shading complexity. In contrast, the CPU’s role appears more static; the Ryzen 5 7600’s six cores and 12 threads can feed frames at a rate far exceeding what the GPU can render at higher resolutions, making the graphics card the clear wall.

At 4K, the gap between Low and Ultra settings is substantial, with a spread of 28.4 FPS (from 69.3 down to 40.9). This indicates that the GPU’s compute units and memory bandwidth are heavily taxed by the Ultra preset’s additional effects, while the CPU continues to keep up with minimal impact. The data implies that for 4K gaming, the RX 6600 XT is the decisive component, and any attempt to improve frame rates must focus on reducing GPU load rather than relying on the processor.

CPU Role

The AMD Ryzen 5 7600 provides a robust foundation for this game, with its six cores and 12 threads running at a base clock of 3.80 GHz and a boost clock of 5.10 GHz. The benchmark data for the CPU shows strong single-thread performance, with a 3dmark_single_thread score of 999 and a passmark_single_thread score of 3910, which is crucial for a fast-paced FPS like Doom that relies heavily on draw calls and game logic. The processor’s 32 MB of shared L3 cache and dual-channel DDR5 memory support with 83.2 GB/s bandwidth further ensure that data can be fed to the GPU without stalling.

Comparing the CPU to its nearest rivals, the Ryzen 5 7600’s average benchmark score of 26617 sits within 0.2% of the AMD Ryzen 7 5800X3D (26574) and 0.3% of the Intel Core i9-11900K (26546). This indicates that the 7600 is not a weak link in the system; its processing power is comparable to those older high-end parts. In the context of Doom’s measured FPS, the CPU’s capability is evident in the 1080p Low results, where the average of 189.4 FPS suggests that the processor can handle frame generation well beyond the GPU’s limits at lower resolutions.

The CPU’s role becomes less prominent as resolution increases. At 4K, the average FPS across all settings (40.9 to 69.3) is far below what the CPU could theoretically support, indicating that the Ryzen 5 7600 is not the bottleneck. The data suggests that the processor is more than adequate for this title, and its performance headroom means that users upgrading the GPU later would see immediate benefits without needing to replace the CPU.

GPU Role

The AMD Radeon RX 6600 XT is the central figure in this analysis, and its specifications explain the FPS trends observed. With 8 GB of GDDR6 memory on a 128-bit bus delivering 256.0 GB/s of bandwidth, the GPU has enough capacity for 1080p and 1440p gaming but struggles at 4K with higher presets. The base clock of 1968 MHz and boost clock of 2589 MHz, along with 2048 shading units, provide a raw compute throughput of 10.60 TFLOPS, which is modest by modern standards but adequate for this game’s engine.

The GPU’s benchmark percentile of 71% vs all GPUs places it above average, and its nearest rival, the NVIDIA GeForce RTX 3070, scores 28238, which is only 0.9% higher. This close competition suggests that the RX 6600 XT is a capable mid-range part. However, the measured FPS in Doom shows its limitations at high resolutions. At 4K Ultra, the average of 40.9 FPS is below the 60 FPS threshold often considered playable, while at 1440p Ultra, the 73.2 FPS figure is more acceptable.

The GPU’s memory bandwidth appears to be a critical factor. The 128-bit bus and 256.0 GB/s bandwidth are sufficient for 1080p, where the High preset achieves 139.1 FPS, but the 4K results indicate that the memory subsystem is overwhelmed by the larger frame buffer demands. The data suggests that the RX 6600 XT is best suited for 1080p and 1440p gaming, with 4K requiring significant settings reductions to maintain playable frame rates.

Measured FPS Breakdown

At 1920x1080, the combo shows its strongest performance. The Low preset yields an average of 189.4 FPS, which drops to 165.6 FPS on Medium and 139.1 FPS on High. The Ultra preset brings the average down to 113.7 FPS, a 40% reduction from Low. These numbers indicate that the GPU is the limiting factor even at 1080p, but the frame rates are high enough for smooth gameplay on high-refresh monitors.

Moving to 2560x1440, the averages decrease across the board. Low settings produce 122.8 FPS, Medium hits 107.2 FPS, High achieves 93.1 FPS, and Ultra falls to 73.2 FPS. The scaling from 1080p to 1440p shows a consistent drop of roughly 35-40% for each preset, which aligns with the increased pixel count. At this resolution, the Ultra preset remains playable, but the margin for high-refresh displays narrows.

At 3840x2160, the performance takes a significant hit. The Low preset averages 69.3 FPS, Medium drops to 60.0 FPS, High manages 49.1 FPS, and Ultra falls to 40.9 FPS. The data shows that only the Low preset approaches a stable 60 FPS at 4K, while higher settings dip below that threshold. This breakdown confirms that the RX 6600 XT is not designed for 4K gaming with this CPU, and users must prioritize either resolution or visual fidelity.
