Doom

The AMD Ryzen 5 5600G paired with the AMD Radeon RX 6650 XT delivers a strong performance profile in Doom, with average frame rates that comfortably exceed the 60 FPS threshold across most settings and resolutions. The measured data indicates that this combination is well-suited for high-refresh-rate 1080p gaming, while remaining viable for 1440p and even playable at 4K with appropriate settings adjustments.

Settings Recommendations

For 1080p, the Ultra preset delivers an average of 122.2 FPS, which is excellent for fast-paced FPS gameplay. However, the High preset achieves 148.3 FPS, representing a 21% performance increase over Ultra while likely offering visually similar results in most scenes. The Medium preset reaches 174.4 FPS, and Low tops out at 200 FPS. Given that Doom is a fast-paced FPS where frame rate directly impacts responsiveness, the High preset at 1080p offers the best balance between visual fidelity and performance, providing a significant 26.1 FPS advantage over Ultra.

At 1440p, the High preset maintains an average of 93.2 FPS, which is above the 90 FPS threshold that many competitive players consider optimal. The Ultra preset drops to 80 FPS, still playable but with a noticeable reduction in smoothness compared to High. The Medium preset reaches 112.5 FPS, and Low achieves 131.7 FPS. For 1440p, High is the recommended preset, as it stays well above 90 FPS while preserving the game's visual quality.

At 4K, the situation changes significantly. The High preset produces 50.7 FPS, which is below the 60 FPS target but still playable for a single-player experience. The Medium preset achieves 59.6 FPS, barely missing the 60 FPS mark. The Low preset reaches 67.9 FPS, providing a smooth experience at the cost of visual detail. The Ultra preset falls to 41.3 FPS, which is not recommended for comfortable gameplay. For 4K, the Low preset is the only option that consistently exceeds 60 FPS, making it the recommended choice for players prioritizing frame rate over graphics.

CPU Role

The AMD Ryzen 5 5600G features 6 cores and 12 threads, with a base clock of 3.90 GHz and a boost clock of 4.40 GHz. This Zen 3 architecture processor, built on the Cezanne codename with a 7 nm process, provides solid single-threaded performance as evidenced by its Cinebench R23 single-core score of 2365. For Doom, which is known to be more GPU-bound than CPU-bound, the processor's capabilities are more than sufficient to feed the GPU at most resolutions.

The CPU's multi-threaded performance, demonstrated by a Cinebench R23 multi-core score of 16758, ensures that background tasks and game logic do not create bottlenecks. Data from the benchmark suite shows the processor ranks in the 78th percentile among all CPUs, with an average benchmark score of 19983. Its nearest rivals include the Intel Core i7-11600H with a deltaPct of 0.2, indicating near-identical performance, and the AMD EPYC 7713P with a deltaPct of -0.2.

At 1080p with the Low preset, the system achieves 200 FPS, suggesting that the CPU is capable of driving very high frame rates when the GPU is not the limiting factor. However, as resolution increases, the frame rate drops consistently, indicating that the GPU becomes the primary bottleneck at higher resolutions. The CPU's 16 MB of L3 cache and dual-channel DDR4 memory support with 51.2 GB/s bandwidth provide adequate data throughput for Doom's engine.

GPU Role

The AMD Radeon RX 6650 XT is built on the RDNA 2.0 architecture with the Navi 23 chip, fabricated on a 7 nm process. It features 8 GB of GDDR6 memory on a 128-bit bus, delivering 280.3 GB/s of bandwidth. The GPU has a base clock of 2055 MHz, a game clock of 2410 MHz, and a boost clock of 2635 MHz. With 2048 shading units, 128 texture mapping units, and 64 raster operation units, the card offers 10.79 TFLOPS of FP32 compute performance.

The GPU's performance in Doom scales predictably with resolution. At 1080p with Medium settings, the card achieves 174.4 FPS, while at 4K with the same settings, it drops to 59.6 FPS. This represents a 65.8% reduction in frame rate when moving from 1080p to 4K, highlighting the GPU's limitations at extreme resolutions. The card's 8 GB VRAM is sufficient for Doom at 4K, as evidenced by the playable frame rates achieved even at Ultra settings.

The RX 6650 XT ranks in the 72nd percentile among all GPUs, with an average benchmark score of 29024. Its nearest rivals include the AMD Radeon RX 6800M with a deltaPct of 0 and the AMD Radeon RX 470 with a deltaPct of 0.1, indicating that the card sits in a tightly contested performance bracket. The GPU's DirectX 12 Ultimate support and Vulkan 1.4 API compatibility are well-suited for Doom's modern rendering requirements.

How This Combo Ranks

In the comprehensive database of tested combinations, this pairing of the AMD Ryzen 5 5600G and AMD Radeon RX 6650 XT ranks 1089 out of 1681 total combos for Doom. This places the system in the lower third of all tested configurations, which is notable given the game's age and the hardware's capabilities. The rank reflects that while this combination performs admirably in absolute terms, many other tested systems offer higher frame rates.

The rank suggests that the combination is not among the top performers for Doom, but it is by no means a poor pairing. The 1080p average frame rates of 148.3 FPS on High settings and 122.2 FPS on Ultra indicate that the system is well above the minimum playable threshold. The 1440p results show the system can handle higher resolutions, though not with the same headroom as more powerful combinations.

The data shows that the CPU and GPU are reasonably balanced for this game, with the GPU becoming the limiting factor at higher resolutions. At 1080p, the CPU's strong single-threaded performance allows the GPU to operate near its maximum potential, resulting in frame rates that approach the GPU's theoretical limits. The rank of 1089 out of 1681 indicates that this is a mid-to-lower-tier combination in the context of all tested systems.

Resolution Scaling

The frame rate scaling across resolutions provides clear insight into which component is limiting performance. Moving from 1080p to 1440p on High settings, the average FPS drops from 148.3 to 93.2, a 37.1% decrease. Moving from 1440p to 4K on the same settings, the frame rate drops from 93.2 to 50.7, a 45.6% decrease. This pattern demonstrates that the GPU is the primary bottleneck at higher resolutions.

At 1080p, the difference between Low and Ultra settings is 77.8 FPS, with Low achieving 200 FPS and Ultra achieving 122.2 FPS. This spread indicates that the GPU has significant headroom at this resolution, and the CPU is capable of driving frame rates well above 200 FPS when the GPU is not constrained. At 1440p, the spread between Low and Ultra is 51.7 FPS, showing that the GPU is becoming more stressed. At 4K, the spread narrows to 26.6 FPS, confirming that the GPU is the dominant limiting factor.

The scaling from Low to Ultra at each resolution shows a consistent pattern: the GPU's workload increases more rapidly than the CPU's, leading to diminishing returns at higher settings. The data indicates that for players targeting 4K, dropping to Low settings is necessary to maintain 60 FPS, while 1440p players can comfortably use High settings and 1080p players can push to Ultra without sacrificing smoothness. The system's performance profile suggests that it is best suited for 1080p and 1440p gaming, with 4K being a secondary consideration that requires careful settings management.
