Doom

CPU Role

The AMD Ryzen 5 7500F is a 6-core, 12-thread processor based on the Zen 4 (Raphael) architecture on the AMD Socket AM5 platform. It runs at a 3.70 GHz base clock and boosts to 5.00 GHz, with a 65 W TDP. This CPU sits in the 77th percentile of all CPUs, with an average benchmark score of 24964. Its nearest rivals are tightly grouped: the Intel Core i7-11850H (avg score 24935, 0.1% ahead), AMD Ryzen 5 8400F (25005, 0.2% behind), Intel Core i7-13620H (24911, 0.2% ahead), and Intel Core 5 210H (24872, 0.4% ahead). The benchmark deltas are negligible, meaning the 7500F is effectively in a dead heat with those four parts.

For Doom, which was released on 2016-05-12, the 7500F’s single-thread performance is the key factor. In the 3dmark single-thread test, it scores 974, and in passmark single-thread it scores 3841. These numbers indicate strong per-core throughput, which matters for a game engine that often relies on one or two main threads for simulation and input handling. The 12 threads give headroom for background tasks, but the data suggests that at high frame rates — like the 242 FPS seen at 1080p Low — the CPU is not the limiting factor. At 1080p with Low settings, the average FPS of 242 is far above what any modern display needs, and the CPU’s multi-thread scores (3dmark max threads at 6379, cinebench r23 multi at 22799) show plenty of parallel capability for the game’s AI and physics.

The CPU’s memory support is DDR5 with a dual-channel bus and 83.2 GB/s memory bandwidth, which is ample for a fast-paced FPS. The L3 cache is 32 MB shared, and L2 is 1 MB per core — these caches help keep frequently used game data close to the cores, reducing latency. In a game like Doom, where arenas are dense with enemies and effects, the 7500F’s architecture is more than sufficient. Its percentile rank of 77 indicates it outperforms most CPUs, but the rival deltas show that upgrading to a similar-tier part would not change Doom’s performance in any meaningful way.

GPU Role

The AMD Radeon RX 6750 XT is a RDNA 2.0 part (Navi 22 chip) with 12 GB of GDDR6 memory on a 192-bit bus, delivering 432.0 GB/s of memory bandwidth. Its clocks are 2150 MHz base, 2600 MHz boost, and 2495 MHz game clock, with memory at 2250 MHz (18 Gbps effective). The GPU has 2560 shading units, 160 TMUs, 64 ROPs, and 40 RT cores. Pixel rate is 166.4 GPixel/s, texture rate 416.0 GTexel/s, and FP32 compute is 13.31 TFLOPS. It ranks in the 71st percentile of all GPUs, with an average benchmark score of 26011. Its nearest rivals are the AMD Radeon R9 M395X (25891, 0.5% ahead), AMD FirePro W7100 (25856, 0.6%), AMD FirePro D700 (25842, 0.7%), and NVIDIA GeForce RTX 3080 Ti Mobile (25740, 1.1% ahead). The deltas are small, but the GPU is clearly ahead of these parts.

In Doom, the GPU’s memory size and bandwidth matter at high resolutions. The game’s textures and effects scale with resolution, and the 12 GB VRAM is never a bottleneck in the measured rows. The GPU’s boost clock of 2600 MHz is high, which helps at 1080p where the frame rate is less memory-bound. The data shows that the GPU is the primary driver of FPS changes when settings move from Low to Ultra. For example, at 1440p, the average FPS drops from 156 at Low to 94 at Ultra — a 62 FPS gap. The GPU’s shading units (2560) and texture rate (416.0 GTexel/s) directly influence how fast the GPU can process the game’s geometry and textures. At 4K Ultra, the GPU drops to 51 FPS, which is playable but not smooth for a fast-paced shooter. The GPU’s FP32 of 13.31 TFLOPS is modest by modern standards, and the data shows that at 4K with High or Ultra, the GPU is fully utilized.

Resolution Scaling

The measured FPS data shows a clear pattern: as resolution increases, average FPS drops, and the gap between settings widens. At 1080p, the GPU is not the limiting factor — the CPU’s single-thread performance can drive the game to very high frame rates. At 1080p Low, the average is 242 FPS; at Medium it is 210 FPS; at High it is 178 FPS; at Ultra it is 145 FPS. The spread from Low to Ultra is 97 FPS, which is a 40% reduction. At 1440p, the averages are 156 FPS (Low), 136 FPS (Medium), 115 FPS (High), and 94 FPS (Ultra). The spread is 62 FPS, a 40% reduction. At 4K, the averages are 85 FPS (Low), 74 FPS (Medium), 62 FPS (High), and 51 FPS (Ultra). The spread is 34 FPS, a 40% reduction.

The percentage drop from 1080p to 4K is consistent: Low goes from 242 to 85 (65% drop), Medium from 210 to 74 (65%), High from 178 to 62 (65%), and Ultra from 145 to 51 (65%). This consistency means the limiting component is the GPU across all settings — the CPU is not causing any extra drop at higher resolutions. The GPU’s memory bandwidth of 432 GB/s and pixel rate of 166.4 GPixel/s are the likely constraints. At 1080p, the GPU can render fast enough to keep up with the CPU, but at 4K, the GPU’s pixel fill rate (166.4 GPixel/s) becomes the ceiling. The fact that the FPS drop is roughly linear with pixel count (1080p has 2.07M pixels, 1440p 3.69M, 4K 8.29M) indicates the GPU is the limiting component, not the CPU. The CPU’s single-thread score of 974 in 3dmark shows it can handle the game’s logic at any resolution, but the GPU’s compute (13.31 TFLOPS) is what drags the frame rate down at 4K.

FAQ

Q: What is the best resolution to play Doom with this CPU/GPU combination?

A: At 1440p, the average FPS ranges from 94 (Ultra) to 156 (Low). At 4K, Ultra drops to 51 FPS, which is below the 60 FPS threshold that many players consider smooth. The data shows that 1440p is the sweet spot for balancing visual quality and performance, as even Ultra averages 94 FPS.

Q: How does the CPU compare to its nearest rivals in this game?

A: The CPU’s nearest rivals all have average benchmark scores within 0.4% of the 7500F. In 3dmark multi-thread tests, the 7500F scores 6379 (max threads), while the rivals are not listed in the game-specific benchmark. Since the game is GPU-bound at 1440p and 4K, the CPU’s performance is not a differentiator in Doom.

Q: Does the GPU have enough VRAM for 4K Ultra in Doom?

A: The GPU has 12 GB GDDR6 memory with 432 GB/s bandwidth. The measured 4K Ultra average is 51 FPS, which indicates that the game uses less than 12 GB; otherwise, the GPU would likely drop to a lower frame rate due to memory swapping. The VRAM size is not the bottleneck — the compute is.

Q: Is the 7500F enough for high refresh-rate monitors at 1080p?

A: Yes. At 1080p Low, the average FPS is 242; at High it is 178. Both exceed the 144 Hz or 165 Hz refresh rate of typical gaming monitors. The CPU’s single-thread score (974 in 3dmark) and boost clock of 5.00 GHz ensure the game logic keeps up with the GPU.

Q: How does the GPU compare to the RTX 3080 Ti Mobile in Doom?

A: The GPU’s average benchmark score is 26011, which is 1.1% higher than the RTX 3080 Ti Mobile (25740). In Doom, the RX 6750 XT delivers 62 FPS at 4K High, while the rival’s exact FPS is not in the pack. The GPU is ahead, but the delta is small.

Q: What settings should I use for a smooth 4K experience?

A: From the data, the only 4K settings that stay above 60 FPS are Low (85 FPS) and Medium (74 FPS). High drops to 62 FPS, which is close to 60 but risky for stuttering. Ultra is below at 51 FPS. For a consistent 60+ FPS, choose Medium.

Settings Recommendations

The measured FPS rows show that the game scales clearly with settings. At 1080p, any setting works, but the difference between Low (242 FPS) and Ultra (145 FPS) is 40%. For a high refresh-rate monitor, Low or Medium gives the highest headroom. At 1440p, Medium (136 FPS) and High (115 FPS) are both playable; Ultra drops to 94 FPS, which is still above 60. At 4K, the choice is more constrained: Low (85 FPS) and Medium (74 FPS) are smooth, High (62 FPS) is borderline, and Ultra (51 FPS) is not recommended for a FPS where quick reactions matter.

Given the game’s release date of 2016, it likely has lower system requirements than modern shooters, but the numbers show that Ultra settings are still demanding on the GPU. For the best visual experience without sacrificing frame rate, the data suggests 1440p High (115 FPS) as the best balance. If you prioritize frame rate over visuals, 1080p Low (242 FPS) gives maximum smoothness. For 4K, Medium is the optimal setting because it delivers 74 FPS and includes the only measured min/max FPS data at that resolution (min 63, max 85), meaning the frame pacing is stable. Ultra at 4K is the only setting that dips below 60 FPS, so avoid it for competitive play. The GPU’s 12 GB VRAM is not a factor, so lowering settings to gain FPS is purely about compute load.

The data is measured and the combo ranks 1696 out of 3712 in Doom. The FPS numbers show that the GPU is the bottleneck at higher resolutions, as the CPU has ample performance to handle the game’s logic. The Medium settings rows include min/max FPS data, which shows consistent frame pacing: at 1080p, the 210 average with a min of 179 and max of 242 means the frame times are stable, with no severe drops. At 1440p, the min of 116 at Medium is still above 60 FPS. At 4K, the Medium min of 63 is just above the 60 FPS threshold, while the max of 85 shows the GPU can occasionally hit higher. The Ultra settings have no min/max data, but the average FPS at 4K (51) is the only sub-60 average across all rows. The GPU’s memory bandwidth of 432 GB/s is sufficient for the game’s texture streaming, as evidenced by the stable min FPS in Medium settings. The GPU’s pixel rate of 166.4 GPixel/s and the 4K resolution of 8.29M pixels mean the GPU is filling 1.37 billion pixels per second at 165 FPS equivalent, but the actual 85 FPS at 4K Low is well below that theoretical maximum, indicating the GPU is compute-limited, not pixel-fill-limited.
