Doom

The AMD Ryzen 5 7600 and AMD Radeon RX 6650 XT pairing delivers strong 1080p performance in Doom, but the GPU becomes the limiting factor at higher resolutions. The data shows this combo ranks 1062nd out of 1681 tested combinations, placing it in the upper-middle tier of systems. The sweet spot for this hardware is 1440p with High settings, where it maintains a smooth 93.5 FPS average. At 4K, the system struggles to maintain high refresh rates, with only the Low preset surpassing 60 FPS. The 6-core, 12-thread CPU with a 5.10 GHz boost clock provides ample headroom, as evidenced by the FPS scaling patterns across resolutions.

Settings Recommendations

The measured FPS rows indicate that the High preset offers the best balance of visual quality and performance for this combo. At 1080p, High delivers 147.4 FPS, which is a 26.7 FPS improvement over Ultra while still maintaining a playable frame rate. The Medium preset at 1080p reaches 174.3 FPS, but the jump from Medium to High costs only 26.9 FPS — a reasonable trade for the visual fidelity increase. The Ultra preset is the most demanding, dropping to 120.7 FPS at 1080p, which remains fluid but sacrifices nearly 27 FPS compared to High.

At 1440p, High produces 93.5 FPS, which is ideal for high-refresh-rate monitors. The Medium preset at 114.8 FPS offers a faster experience, but the visual downgrade is noticeable in a fast-paced FPS. Low at 128.3 FPS is only 13.5 FPS faster than Medium, making it a poor value in visual terms. For 4K, the data suggests avoiding anything above Low: the Low preset achieves 70.3 FPS, while Medium drops to 63.6 FPS and High falls to 51.9 FPS. Ultra at 4K is essentially unplayable at 39.8 FPS. The recommendation is to prioritize High at 1080p and 1440p, and only use Low at 4K for a playable experience.

GPU Role

The Radeon RX 6650 XT features 8 GB of GDDR6 memory on a 128-bit bus with 280.3 GB/s bandwidth. The GPU clock speeds are notable: a base clock of 2055 MHz, a game clock of 2410 MHz, and a boost clock of 2635 MHz. These clocks are high for the RDNA 2.0 architecture, and the 2048 shading units process data at 10.79 TFLOPS FP32. The 32 ray accelerators are present but Doom does not heavily utilize ray tracing, so the traditional rasterization performance matters more.

The GPU's 72nd percentile ranking among all GPUs indicates it is a mid-range performer, and the measured FPS data confirms this. At 1080p, the GPU is not the primary bottleneck — the system achieves 202.7 FPS on Low, which suggests the CPU is capable of feeding the GPU efficiently. However, at 4K, the GPU's 128-bit memory bus and 8 GB capacity become limiting factors. The 4K Ultra result of 39.8 FPS is 80.9 FPS lower than the 1080p Ultra result, showing a steep performance cliff. The memory bandwidth of 280.3 GB/s is adequate for 1080p and 1440p but struggles to sustain high fill rates at 4K, particularly with the 168.6 GPixel/s pixel rate.

Resolution Scaling

The FPS scaling from 1080p to 4K reveals a GPU-bound scenario at higher resolutions. At High settings, the average FPS drops from 147.4 at 1080p to 93.5 at 1440p (a 36.6% reduction), then further to 51.9 at 4K (a 44.5% reduction from 1440p). This is a classic GPU-limited pattern where the workload scales with pixel count. In contrast, the Low preset shows a smaller relative drop: 202.7 FPS at 1080p, 128.3 at 1440p (36.7% lower), and 70.3 at 4K (45.2% lower from 1440p). The consistent percentage drops across settings indicate the GPU is the primary limiter once resolution increases.

The data also shows that the gap between Low and Ultra widens at higher resolutions. At 1080p, Low is 82 FPS faster than Ultra. At 1440p, the gap is 48.5 FPS. At 4K, the gap narrows to 30.5 FPS. This narrowing suggests that at 4K, the GPU is so saturated that even reducing settings from Ultra to Low cannot fully compensate for the pixel workload. The 4K Low result of 70.3 FPS is only 17.6 FPS higher than 1440p Ultra at 79.8 FPS, showing that resolution has a more significant impact than settings in this game for this hardware.

Measured FPS Breakdown

At 1920x1080, the combo delivers excellent performance across all presets. The Low preset achieves 202.7 FPS, Medium reaches 174.3 FPS, High produces 147.4 FPS, and Ultra bottoms out at 120.7 FPS. The spread of 82 FPS between Low and Ultra gives players substantial flexibility. The 120.7 FPS Ultra result is still above typical 60 Hz refresh rates, so players with standard monitors can run maximum settings without issue.

At 2560x1440, the performance remains strong. Low hits 128.3 FPS, Medium reaches 114.8 FPS, High produces 93.5 FPS, and Ultra drops to 79.8 FPS. The 79.8 FPS Ultra result is playable but not ideal for 144 Hz displays. The High preset at 93.5 FPS is the best compromise, offering 13.7 FPS more than Ultra while retaining most visual features. The 128.3 FPS Low result shows the CPU is not a bottleneck at this resolution, as the GPU can still push high frame rates when settings are reduced.

At 3840x2160, the GPU becomes the clear bottleneck. Low achieves 70.3 FPS, Medium reaches 63.6 FPS, High produces 51.9 FPS, and Ultra falls to 39.8 FPS. Only the Low preset clears 60 FPS, and even then it is marginal. Medium and High are playable but not smooth, and Ultra is not suitable for competitive play. The 31.5 FPS difference between Low and Ultra at 4K is the smallest spread across all resolutions, confirming the GPU's saturation point.

How This Combo Ranks

The combo ranks 1062nd out of 1681 tested combinations in Doom, placing it in the 63rd percentile of all systems. This rank reflects a capable but not top-tier pairing. The GPU's average benchmark score of 29024 positions it near several close rivals: the AMD Radeon RX 6800M scores 29011 (0% difference), the AMD Radeon RX 470 scores 28996 (0.1% ahead), and the Intel Arc A370M scores 29175 (0.5% behind). The RX 6650 XT is effectively tied with these competitors, meaning the in-game rank is determined more by the CPU pairing than the GPU alone.

The CPU contributes significantly to this ranking. The Ryzen 5 7600 has an average benchmark score of 26617, which is 0.2% behind the AMD Ryzen 7 5800X3D (26574) and 0.2% ahead of the AMD EPYC 8024P (26555). The Intel Core i9-12900HK scores 26672, placing it 0.2% ahead of the 7600. These near-identical CPU scores suggest that the 1062nd rank is driven by the GPU's mid-range positioning rather than any CPU deficiency. The data shows this combo should handle Doom well at 1080p and 1440p, but it will not compete with high-end systems at 4K.

CPU Role

The AMD Ryzen 5 7600 is a 6-core, 12-thread processor based on Zen 4 architecture with a 5 nm process. Its base clock of 3.80 GHz boosts to 5.10 GHz, and the 32 MB of shared L3 cache provides fast access to game data. The CPU's 83rd percentile ranking among all CPUs indicates strong single-thread and multi-thread performance. The Cinebench R23 scores are telling: 22992 multi-core and 3246 single-core, showing robust processing power for a 65 W TDP part.

In Doom, the CPU's role is evident from the FPS scaling. At 1080p Low, the system reaches 202.7 FPS, which is a high frame rate that requires strong CPU performance to avoid bottlenecking the GPU. The single-thread score of 3246 in Cinebench R23 supports this, as Doom relies heavily on a few threads for game logic and draw calls. The 12 threads handle background tasks and streaming efficiently, preventing frame hitches. The 83.2 GB/s memory bandwidth on DDR5 also helps feed the GPU quickly, though the 128-bit GPU bus becomes the limiting factor at 4K.

The CPU's performance relative to rivals is tight. The Ryzen 7 5800X3D scores 26574 on average, just 0.2% below the 7600's 26617. This means the 7600 is effectively as fast as the 5800X3D in this game, despite the latter's 3D V-Cache. The 7600 also edges out the Intel Core i9-11900K by 0.3% (26546), showing that the Zen 4 architecture holds up well against older high-end parts. The data indicates that the CPU is not the bottleneck in Doom for this combo; the GPU determines the final frame rates, particularly at 1440p and above.
