Doom

The AMD Ryzen 5 5600GT paired with the AMD Radeon RX 6800 XT delivers exceptional performance in Doom, making it a formidable combo for high-refresh-rate and 4K gaming. This pairing leverages six Zen 3 cores and a high-end RDNA 2 GPU, resulting in frame rates that consistently exceed the thresholds for smooth, competitive play across all tested resolutions and settings. The data shows a system capable of handling the game's fast-paced action with significant headroom, even at the most demanding graphical presets.

Settings Recommendations

For this specific combination, the "High" preset offers the most balanced experience across all resolutions. At 1920x1080, High produces an average of 211.3 FPS, which is only slightly below the 251 FPS of Medium but comes with a substantial visual quality improvement. The jump to Ultra provides diminishing returns, as the average drops to 174.1 FPS, a 17.6% decrease from High, which may be noticeable on a 240Hz display but is still perfectly playable. At 2560x1440, High again proves optimal, delivering 141.7 FPS, which comfortably exceeds the 120Hz refresh rate common in modern monitors. While Ultra at this resolution still hits 113.4 FPS, the extra visual fidelity comes at a cost of a 20% performance reduction, making High the superior choice for maintaining high frame times. At 3840x2160, High is the clear sweet spot, achieving 75 FPS, which is ideal for a 60Hz or 75Hz 4K display. Ultra dips to 63.8 FPS, which is still playable but risks occasional stutters on VRR displays with a lower refresh rate floor. The "Low" preset is only recommended for extreme competitive play where maximum frame rates are paramount, as it yields 289.5 FPS at 1080p, but the visual downgrade is severe and unnecessary given the hardware's capability.

CPU Role

The Ryzen 5 5600GT's six cores and twelve threads, based on the Zen 3 architecture, are more than sufficient to keep the RX 6800 XT fed in Doom. The CPU's boost clock of 4.60 GHz ensures strong single-thread performance, which is critical for the game's core logic and input responsiveness. The benchmark data suggests the CPU is not a bottleneck in this pairing. At 1080p with Low settings, the system reaches 289.5 FPS, which indicates the game engine is being pushed to its limits, but the CPU's ability to sustain this frame rate demonstrates its headroom. The CPU's 16 MB of L3 cache helps reduce memory latency, and its dual-channel DDR4 memory support with a bandwidth of 51.2 GB/s provides adequate data throughput. The Ryzen 5 5600GT sits in the 78th percentile of all CPUs, and its average benchmark score of 20740 places it nearly identical to the Intel Core i7-10700 (deltaPct 0) and the AMD Ryzen 5 5600X (deltaPct 0.3). This indicates that its processing power is on par with established mid-to-high-end desktop processors, making it a capable partner for the powerful GPU.

GPU Role

The AMD Radeon RX 6800 XT is the dominant component in this combo, and its specifications clearly dictate the performance envelope in Doom. With 16 GB of GDDR6 memory on a 256-bit bus, providing 512.0 GB/s of bandwidth, the GPU has ample resources to handle high-resolution textures and geometry without stuttering. The boost clock of 2250 MHz, combined with 4608 shading units, drives the high frame rates observed. The GPU's performance is strong, placing it in the 87th percentile of all GPUs. Its average benchmark score of 49982 is competitive, edging out the Intel Arc A550M by 0.5% and the NVIDIA GeForce RTX 4070 Ti SUPER by 2.6%. This high-bandwidth, high-throughput design is well-suited for Doom's fast-paced rendering. The data shows that the GPU is the primary limiter at higher resolutions and settings. The transition from Low to Ultra at 1080p sees an average FPS drop from 289.5 to 174.1, a 39.8% reduction, which is consistent with a GPU-bound workload. This indicates that while the CPU is capable, the RX 6800 XT's raw compute power is what ultimately determines the frame rate ceiling at maximum quality.

How This Combo Ranks

The combination of the Ryzen 5 5600GT and RX 6800 XT achieves a combo rank of 597 out of 1681 tested combinations in Doom. This places it in the top 35.5% of all systems, which is a strong result given that the CPU is a more budget-oriented part while the GPU is a high-end model. The ranking suggests that the overall system is well-balanced for this title, though not at the absolute peak of performance. The high GPU percentile (87th) versus the lower CPU percentile (78th) indicates that the GPU is doing most of the heavy lifting. The combo's rank is likely held back by the CPU's performance in CPU-bound scenarios, such as the 1080p Low preset, but the GPU's strength ensures that the system remains competitive. This pairing is an effective match because the GPU can fully express its capabilities at 1440p and 4K, where the CPU's limitations are less impactful. The data implies that for a system ranking in the top third, this combo delivers a premium gaming experience, particularly for users prioritizing high visual fidelity.

Resolution Scaling

The FPS data across resolutions reveals a classic scaling pattern that confirms the GPU as the primary bottleneck. Moving from 1920x1080 to 2560x1440 at High settings, the average frame rate drops from 211.3 to 141.7 FPS, a reduction of 32.9%. This is a substantial decrease, typical of a GPU-bound workload, as the pixel count increases by 78%. The scaling from 2560x1440 to 3840x2160 is even more pronounced. At High settings, the average drops from 141.7 to 75 FPS, a 47.1% reduction. This steep drop indicates that the RX 6800 XT is being pushed to its limits at 4K, and the CPU's role becomes less significant. The difference between Low and Ultra settings at each resolution further illustrates this. At 1080p, the spread between Low and Ultra is 115.4 FPS, while at 4K, the spread narrows to 36.4 FPS. This narrowing spread at higher resolutions is a clear indicator that the GPU is the limiting factor. The CPU can easily handle the game logic, but the GPU's shader and memory throughput are what determine the final frame rate at high pixel counts.

Measured FPS Breakdown

The measured FPS data provides a comprehensive view of the combo's performance across all settings and resolutions. At 1920x1080, the system is exceptionally fast: Low settings yield an average of 289.5 FPS, Medium produces 251 FPS, High achieves 211.3 FPS, and Ultra still maintains a very high 174.1 FPS. These numbers are all well above the refresh rates of most gaming monitors, making the system overkill for 1080p gaming. At 2560x1440, performance remains excellent: Low settings average 188.5 FPS, Medium hits 164.1 FPS, High delivers 141.7 FPS, and Ultra stays above 100 FPS with an average of 113.4 FPS. This resolution is the sweet spot for the combo, offering a perfect balance of high detail and high frame rates. At 3840x2160, the system remains very capable: Low settings achieve 100.2 FPS, Medium averages 91.2 FPS, High provides a solid 75 FPS, and Ultra dips to 63.8 FPS. The data shows that even at 4K Ultra, the game is playable, but for a consistently smooth experience, the High preset at 4K is the recommended choice. These measured results confirm that the Ryzen 5 5600GT and RX 6800 XT combo is a high-performance pairing, capable of delivering an excellent Doom experience at any resolution, with the caveat that 4K Ultra is demanding and that High settings are the most practical maximum for a locked frame rate.
