Doom

The AMD Ryzen 5 2600 paired with the AMD Radeon RX 6600 XT delivers a remarkably consistent experience in Doom, with the data showing that the graphics card is the primary driver of performance at every resolution. The combination ranks in the bottom third of tested systems, yet it still manages to produce playable frame rates at 4K and excellent performance at 1440p, revealing a balanced pairing that leans heavily on the GPU's capabilities.

Resolution Scaling

The measured FPS data shows a clear and predictable scaling pattern as resolution increases, with the most significant performance drop occurring between 1440p and 4K. At 1080p High settings, the system achieves 142.7 FPS average, which drops to 90.4 FPS at 1440p High — a reduction of approximately 37%. Moving from 1440p High to 4K High brings the frame rate down to 50.8 FPS, another substantial drop of about 44%. This scaling behavior indicates that the GPU is the limiting component, as the frame rate penalty from increasing pixel count is consistent with the RX 6600 XT's 8 GB of VRAM and 128-bit memory bus.

The pattern holds across all settings presets. At Low settings, the system goes from 189.4 FPS at 1080p to 124 FPS at 1440p, then down to 66 FPS at 4K. Medium settings show the same trajectory: 169.1 FPS at 1080p, 105.8 FPS at 1440p, and 61.8 FPS at 4K. Ultra settings are the most demanding, producing 112.7 FPS at 1080p, 75.4 FPS at 1440p, and dropping to 41 FPS at 4K. The consistency of these drops across all settings strongly suggests that resolution is the dominant factor, with the CPU's 6 cores and 12 threads providing sufficient headroom even at lower resolutions.

The fact that 4K Ultra falls below 60 FPS at 41 FPS average indicates that the RX 6600 XT's 10.60 TFLOPS of FP32 performance is not sufficient for the highest fidelity at that resolution. However, the 4K High result of 50.8 FPS shows that a modest reduction in settings can bring 4K into a playable range, while 4K Low at 66 FPS demonstrates that the hardware is capable of smooth 4K gameplay when graphical demands are reduced.

CPU Role

The AMD Ryzen 5 2600 is a 6-core, 12-thread processor based on the Zen architecture, manufactured on a 12 nm process by GlobalFoundries. Its base clock of 3.40 GHz and boost clock of 3.90 GHz, combined with 16 MB of shared L3 cache, position it as a mid-range desktop chip from 2018. In the context of Doom, a fast-paced FPS that typically benefits from high single-thread performance, the CPU's Cinebench R23 single-core score of 1579 and multi-core score of 11186 provide context for its capabilities.

The benchmark results indicate that the CPU is not the bottleneck in this pairing, even at 1080p where frame rates are highest. At 1080p Low, the system achieves 189.4 FPS, which is a demanding scenario for any processor. The fact that the frame rate continues to scale upward from Medium (169.1 FPS) to Low (189.4 FPS) at 1080p suggests that the CPU is capable of feeding the GPU with enough data to maintain high frame rates. The Ryzen 5 2600's PassMark single-thread score of 2239 and multithread score of 13160 place it in the 77th percentile among all CPUs, indicating solid performance for its generation.

However, the CPU's role becomes more evident when examining the scaling from 1440p to 1080p. At High settings, the jump from 90.4 FPS at 1440p to 142.7 FPS at 1080p represents a 58% increase, which is substantial but not as large as the theoretical pixel count difference would suggest. This could indicate that the CPU is beginning to limit performance at 1080p, though the frame rates remain highly playable. The Ryzen 5 2600's nearest rivals in aggregate benchmarks include the Intel Core i5-1345U (0.4% faster) and AMD Ryzen 5 7530U (0.6% slower), showing that it remains competitive with much newer mobile processors in general compute tasks.

GPU Role

The AMD Radeon RX 6600 XT is the clear performance driver in this combination, with its RDNA 2.0 architecture and 7 nm process from TSMC providing substantial graphics horsepower. The GPU features 8 GB of GDDR6 memory on a 128-bit bus, delivering 256.0 GB/s of bandwidth, along with 2048 shading units, 128 texture mapping units, and 64 raster operation units. Its boost clock of 2589 MHz and game clock of 2359 MHz, combined with 10.60 TFLOPS of FP32 performance, make it a capable mid-range graphics card from 2021.

The GPU's influence on Doom's performance is evident across all resolution and settings combinations. At 4K Ultra, the card produces 41 FPS, which is below the playable threshold for a fast-paced shooter, while at 4K High it achieves 50.8 FPS. The transition from Ultra to High settings at 4K yields a 24% improvement in frame rate, while moving from High to Medium (61.8 FPS) provides another 22% gain. These improvements are directly attributable to the GPU's ability to handle reduced shading and texture workloads more efficiently.

The RX 6600 XT's 8 GB VRAM capacity is likely a limiting factor at 4K, where high-resolution textures can exceed this amount. The 256.0 GB/s memory bandwidth, while adequate for 1080p and 1440p, becomes strained at 3840x2160 resolution. The GPU's PassMark G3D score of 16461 places it in the 71st percentile among all GPUs, with nearest rivals including the NVIDIA GeForce GTX 980 Ti (0.1% faster) and NVIDIA GeForce RTX 3070 (0.9% faster in aggregate benchmarks). This shows that the RX 6600 XT punches above its weight class in general graphics performance, though Doom's specific workload reveals its limitations at higher resolutions.

How This Combo Ranks

The AMD Ryzen 5 2600 + AMD Radeon RX 6600 XT combination ranks 1217 out of 1681 tested combos in Doom, placing it in the bottom 28% of all systems. This ranking reflects the age of the CPU relative to the GPU, as the Ryzen 5 2600 from 2018 pairs with a 2021 graphics card. The combo's performance in Doom is still respectable, but the ranking indicates that many other combinations of processors and GPUs achieve higher frame rates in this title.

The ranking position is somewhat surprising given the GPU's capabilities, suggesting that Doom's engine may be more CPU-sensitive than typical for an FPS title. The Ryzen 5 2600's Zen architecture, while competent, lacks the single-thread performance of newer processors, which could be limiting the combo's potential in Doom. The CPU's percentile ranking of 77th among all CPUs and the GPU's 71st percentile ranking both suggest mid-pack performance, but their combination produces a result that is lower than either component's individual standing might indicate.

When compared to other tested combinations, this pairing sits in a region where frame rates are generally playable but not exceptional. The data shows that the combo achieves 142.7 FPS at 1080p High, which is solidly in the high-refresh-rate territory for 144Hz monitors, and 90.4 FPS at 1440p High, which is suitable for 60Hz to 120Hz displays. However, the 4K results fall short of the 60 FPS target for most settings, limiting the combo's appeal for 4K gaming.

Measured FPS Breakdown

At 1080p resolution, the system delivers its strongest performance across all settings. Low settings produce 189.4 FPS average, Medium settings yield 169.1 FPS, High settings achieve 142.7 FPS, and Ultra settings drop to 112.7 FPS. These numbers indicate that 1080p is well within the capabilities of this hardware, with even Ultra settings providing frame rates above 100 FPS.

Moving to 1440p, the performance remains strong but shows the expected decline. Low settings deliver 124 FPS, Medium settings produce 105.8 FPS, High settings achieve 90.4 FPS, and Ultra settings yield 75.4 FPS. All of these results are above 60 FPS, making 1440p a viable resolution for this combo at any settings preset.

At 4K resolution, the performance drops significantly. Low settings produce 66 FPS, Medium settings achieve 61.8 FPS, High settings deliver 50.8 FPS, and Ultra settings drop to 41 FPS. Only Low and Medium settings maintain an average above 60 FPS at 4K, while High and Ultra fall below the smooth-playability threshold. The gap between 1440p and 4K is substantial, with the 4K High result of 50.8 FPS representing a 44% reduction from the 1440p High result of 90.4 FPS.

Settings Recommendations

Based on the measured data, the optimal settings depend on the target resolution and desired frame rate. For 1080p gaming, Ultra settings at 112.7 FPS provide the best visual quality while maintaining frame rates well above 60 FPS and even above 100 FPS, making this the recommended configuration for high-refresh-rate monitors. The jump from High (142.7 FPS) to Ultra (112.7 FPS) costs about 21% performance but likely provides meaningful visual improvements.

For 1440p gaming, High settings at 90.4 FPS offer the best balance of visual fidelity and smoothness, with the option to drop to Medium (105.8 FPS) for additional headroom on 120Hz displays. Ultra settings at 75.4 FPS are also viable, but the 20% performance penalty from High may not justify the visual gains in a fast-paced game like Doom.

At 4K, Medium settings at 61.8 FPS provide the only consistently smooth experience above 60 FPS, while High settings at 50.8 FPS may be acceptable for players who prioritize visuals over frame rate. Low settings at 66 FPS are also viable but sacrifice significant visual quality. Given that Doom is a fast-paced FPS where reaction time matters, the recommendation is to prioritize frame rate: use Medium settings at 4K, High at 1440p, and Ultra at 1080p.
