Doom

This combo pairs AMD’s 6-core Ryzen 5 7500F with the Radeon RX 6800 XT, and in Doom the data shows a pairing that is heavily skewed toward GPU limitation at higher resolutions, with CPU headroom becoming apparent only at 1080p. The measured results indicate a smooth experience across the board, but the nature of that smoothness changes depending on where you point the resolution slider.

Resolution Scaling

The FPS drop from 1080p to 4K is steep and consistent, which is the classic signature of a GPU-bound scenario. At High settings, the average frame rate falls from 214.1 FPS at 1920x1080 to 139.3 FPS at 2560x1440, then down to 76.3 FPS at 3840x2160. That is a 64.4% reduction in FPS when moving from 1080p to 4K at High settings, and the pattern holds across all quality presets. At Low settings, the slide is even more dramatic in absolute terms: 290.2 FPS at 1080p drops to 189.5 FPS at 1440p and then to 104.1 FPS at 4K.

The scaling curve tells you that the RX 6800 XT is doing the heavy lifting. The gap between 1080p and 1440p is large, but the gap between 1440p and 4K is proportionally larger, which is expected when pixel count quadruples. The fact that 4K Ultra still manages 63.7 FPS average is notable, but it is also the only preset where the frame rate dips below the 60 FPS mark. The data suggests that if you are targeting 4K, you will need to dial back from Ultra to High to stay comfortably above 60 FPS, as the jump from 63.7 FPS to 76.3 FPS at High is a meaningful 19.8% improvement.

Conversely, the scaling at 1080p suggests the CPU is starting to become a factor. The difference between Low and Ultra at 1080p is 290.2 FPS versus 173.2 FPS, a 67.5% spread. At 4K, the same preset spread is 104.1 FPS versus 63.7 FPS, which is a 63.4% spread. The relative consistency of these percentages indicates that the GPU is still the primary limiter even at 1080p, but the absolute numbers are high enough that you are unlikely to notice any CPU bottleneck in practical gameplay.

How This Combo Ranks

In the database of tested combinations for Doom, this specific pairing of the Ryzen 5 7500F and RX 6800 XT lands at rank 590 out of 1681 combos. That places it in the upper third of all tested systems, which is a solid position for a mid-generation pairing. The percentile placement is not in the top tier, but it is respectable given that the list likely includes many higher-end GPUs and newer CPUs.

The rank reflects the balance of the two components. The RX 6800 XT sits at the 87th percentile among all GPUs, while the Ryzen 5 7500F is at the 82nd percentile among all CPUs. Neither component is a flagship, but both are well above average, and their combined performance in Doom is competitive. The data shows that this combo outperforms roughly 65% of all tested configurations in this specific game, which is a strong result for a system built around a 6-core processor and a last-generation high-end GPU.

When looking at the CPU’s nearest rivals, the Ryzen 5 7500F is effectively tied with several other processors. It scores within 0.4% of the Intel Core i7-11850H, the AMD Ryzen 7 2700X, and the AMD Ryzen 5 8400F. The deltaPct values are all under 1%, meaning that in general compute benchmarks, swapping between these CPUs would produce no noticeable difference. The GPU’s nearest rivals tell a similar story, with the RX 6800 XT sitting within 2.6% of the NVIDIA GeForce RTX 4070 Ti SUPER and within 1.7% of the NVIDIA RTX A1000. This suggests that the overall combo rank is driven more by the GPU’s performance class than by any CPU advantage.

GPU Role

The Radeon RX 6800 XT is built on the RDNA 2.0 architecture with the Navi 21 chip, manufactured on a 7 nm process at TSMC. It packs 4608 shading units, 288 texture mapping units, and 128 raster operation units, along with 72 ray tracing cores. The memory subsystem is a 16 GB pool of GDDR6 on a 256-bit bus, delivering 512.0 GB/s of bandwidth. Those specs are directly relevant to Doom’s performance profile, as the game is known for being demanding on fill rate and memory bandwidth at higher resolutions.

The clock behavior is worth noting. The base clock is 1825 MHz, the game clock is 2015 MHz, and the boost clock is 2250 MHz. The memory runs at 2000 MHz with 16 Gbps effective speed. In practice, the boost clock is what matters for sustained frame rates, and the 2250 MHz figure is high enough to keep the GPU ahead of the CPU in most scenarios. The pixel rate is 288.0 GPixel/s and the texture rate is 648.0 GTexel/s, which explains why the card handles 1440p High at 139.3 FPS without breaking a sweat.

The FP32 compute throughput is 20.74 TFLOPS, which is a healthy number for a card of this generation. The 16 GB VRAM capacity is more than sufficient for Doom at any settings, as the game does not typically exceed 8 GB even at 4K Ultra. The data shows that the GPU is the primary driver of performance differences between resolutions and settings, and its 87th percentile ranking among all GPUs aligns with the observed frame rates.

Measured FPS Breakdown

At 1920x1080, the frame rates are high across the board. Low settings produce 290.2 FPS average, Medium drops to 253.1 FPS, High reaches 214.1 FPS, and Ultra settles at 173.2 FPS. These numbers indicate that at 1080p, you have massive headroom, and even the most demanding preset will easily exceed the refresh rate of any standard monitor. The spread from Low to Ultra is 117 FPS, which is the largest absolute difference of any resolution.

Moving to 2560x1440, the averages are still very playable. Low settings yield 189.5 FPS, Medium gives 164.6 FPS, High produces 139.3 FPS, and Ultra drops to 111.3 FPS. The transition from 1080p to 1440p reduces performance by roughly 35-40% depending on the preset, which is consistent with the increase in pixel count. At 1440p Ultra, you are still well above 100 FPS, which is excellent for a fast-paced FPS.

At 3840x2160, the performance scales down further. Low settings average 104.1 FPS, Medium drops to 86.8 FPS, High reaches 76.3 FPS, and Ultra falls to 63.7 FPS. The Ultra preset is the only configuration in the entire dataset that dips below 70 FPS, and it is also the only one that approaches the 60 FPS threshold. For 4K gaming, High settings appear to be the sweet spot, offering a 19.8% improvement over Ultra while maintaining visual fidelity.

CPU Role

The AMD Ryzen 5 7500F is a 6-core, 12-thread processor based on the Zen 4 architecture, codenamed Raphael. It has a base clock of 3.70 GHz and a boost clock of 5.00 GHz, with a 65 W TDP. The cache configuration includes 64 KB of L1 per core, 1 MB of L2 per core, and 32 MB of shared L3 cache. The memory support is DDR5 with dual-channel operation, providing 83.2 GB/s of bandwidth.

In Doom, the CPU’s role is secondary to the GPU, but it is not irrelevant. The game is well-threaded, and the 12 threads are sufficient to avoid bottlenecks. The single-thread performance is strong, as evidenced by a 3DMark single-thread score of 974 and a Cinebench R23 single-core score of 3218. Multi-threaded performance is also solid, with a Cinebench R23 multicore score of 22799.

The data suggests that at 1080p Low settings, where the GPU is less stressed, the CPU is able to push 290.2 FPS, which is close to the practical limit for many display interfaces. The boost clock of 5.00 GHz is high enough to keep up with the GPU’s frame output. The 82nd percentile ranking among all CPUs indicates that this processor is well above average, and its nearest rivals are all within 0.4% of its average benchmark score, meaning that any of those CPUs would produce nearly identical results in this game.

The 65 W TDP and 5 nm process node mean the CPU runs cool and efficient, which is beneficial for sustained gaming sessions. The PCIe Gen 5 support with 24 lanes ensures that the GPU has plenty of bandwidth, although the RX 6800 XT only uses PCIe 4.0 x16, so this is not a limiting factor. The CPU’s 6 cores and 12 threads are adequate for Doom, and the data shows no signs of a CPU-induced frame cap at any resolution or settings combination.
