Doom

The Intel Core Ultra 7 265 and NVIDIA GeForce RTX 3080 combination delivers exceptionally high frame rates in Doom, with all tested settings at every resolution clearing the 60 FPS playability threshold by a wide margin. The data shows a system that is heavily GPU-bound at higher resolutions, while the CPU's strong single-thread performance ensures no bottleneck at lower settings where frame rates exceed 300 FPS.

Similar Performance Alternatives

The nearest CPU rivals to the Intel Core Ultra 7 265 based on average benchmark scores are a mix of AMD EPYC server processors and a sister Intel part. The AMD EPYC 4464P scores 64823, which is 0.3% higher than the Ultra 7 265's 64640 average, making it the closest performance match. The Intel Core Ultra 7 265F is effectively identical, with a score of 64438, just 0.3% lower. The AMD EPYC 7343 trails by 0.7% with a score of 64202, while the AMD EPYC 9124 leads by 0.7% at 65104. These deltas are minimal, meaning any of these processors would behave nearly identically in Doom, particularly given that the game's frame rates at 4K Ultra (63 FPS) and 1440p Ultra (117 FPS) suggest the GPU is the limiting factor.

On the GPU side, the RTX 3080's nearest rivals are unexpected. The NVIDIA P106-100 scores 23249, just 0.3% higher than the RTX 3080's 23172 average benchmark score. The AMD Radeon Pro Vega 16 matches that 0.3% delta at 23250. The AMD Radeon RX 6600M scores 23273 (0.4% higher), and the AMD Radeon R9 M290X scores 23276 (0.4% higher). Despite the wide spread in actual gaming performance these parts might exhibit in other titles, the aggregate benchmark data places them within a fractional percentage of the RTX 3080. In Doom specifically, these rivals would likely produce comparable frame rates at the same settings, though the RTX 3080's 10 GB of GDDR6X memory and 760.3 GB/s bandwidth provide a substantial advantage in memory-intensive scenes that these aggregate scores do not fully capture.

CPU and GPU Roles

The division of labor between the Intel Core Ultra 7 265 and the RTX 3080 shifts dramatically across resolutions. At 1920x1080, the CPU's influence is most apparent. The Low preset achieves 301 FPS average, while the Ultra preset drops to 181 FPS. The scaling from Low to Ultra at 1080p represents a 120 FPS reduction (approximately 40% lower), which is the largest relative drop across all resolutions. This indicates that at 1080p, the GPU's shading workload is the primary constraint, but the CPU's 20 cores and 5.30 GHz boost clock are sufficient to feed the RTX 3080 even at the 301 FPS Low preset ceiling.

At 2560x1440, the pattern shifts. Low preset delivers 195 FPS average, and Ultra drops to 117 FPS. The gap between Low and Ultra narrows to 78 FPS (40% lower), but the absolute ceiling drops by 106 FPS compared to 1080p Low. This suggests the GPU is beginning to dominate the performance equation, as the pixel fill rate and memory bandwidth demands at 1440p constrain the maximum frame rate. The RTX 3080's 164.2 GPixel/s pixel rate and 760.3 GB/s bandwidth become the limiting factors.

At 3840x2160, the GPU's role is fully dominant. Low preset averages 105 FPS, while Ultra drops to 63 FPS. The difference between Low and Ultra is 42 FPS (40% lower), but the maximum achievable frame rate has fallen by 196 FPS compared to 1080p Low. The CPU's contribution is minimal here; the data shows that even with a lower-performing processor, the 4K Ultra result of 63 FPS would likely remain similar because the RTX 3080 is saturated by the 8.3 million pixel workload. The CPU's single-thread score of 5960 in Cinebench R23 and Passmark single-thread score of 4689 ensure it never becomes a bottleneck, but at 4K the GPU is clearly the performance arbiter.

Measured FPS Breakdown

At 1920x1080, the combination produces its highest frame rates. The Low preset averages 301 FPS, with no minimum or maximum reported. Medium averages 262 FPS, with a minimum of 223 FPS and a maximum of 301 FPS. High averages 221 FPS. The Ultra preset averages 181 FPS. The spread between Low and Ultra at 1080p is 120 FPS, showing that Doom's settings have a substantial impact on the RTX 3080's workload even at this resolution.

Moving to 2560x1440, the frame rates remain high but show the expected reduction. Low averages 195 FPS. Medium averages 170 FPS, with a minimum of 144 FPS and a maximum of 195 FPS. High averages 143 FPS. Ultra averages 117 FPS. The difference between Low and Ultra here is 78 FPS. The minimum frame rate at Medium (144 FPS) is still well above the 60 FPS playable threshold, indicating consistent performance without dips below playability.

At 3840x2160, the frame rates are lower but still comfortably playable. Low averages 105 FPS. Medium averages 92 FPS, with a minimum of 78 FPS and a maximum of 106 FPS. High averages 78 FPS. Ultra averages 63 FPS. The gap between Low and Ultra is 42 FPS. The minimum recorded frame rate across all 4K tests is 78 FPS at Medium, which is 18 FPS above the playable threshold. The Ultra preset's 63 FPS average sits just 3 FPS above the 60 FPS threshold, making it the most demanding configuration tested.

How This Combo Ranks

The Intel Core Ultra 7 265 and RTX 3080 combination ranks 1054 out of 3712 tested combos in Doom. This places it in the 28th percentile of all combinations, meaning roughly 72% of tested systems perform better in this game. The ranking is influenced by the RTX 3080's age; its percentileVsAllGpus of 68 indicates it outperforms 68% of all GPUs in the database, but newer GPUs with higher bandwidth and more shading units dominate the top ranks. The CPU's percentileVsAllCpus of 93 is strong, but in Doom, which scales heavily with GPU performance at higher resolutions, the GPU's position drags the combined ranking down. The 4K Ultra result of 63 FPS, while playable, is a modest outcome compared to systems built around newer GPUs that would achieve higher average frame rates at the same settings. The 1080p Low result of 301 FPS is likely capped by the game's engine or refresh rate rather than hardware limits, so the ranking at lower resolutions is less indicative of the hardware's true capabilities.

Best Settings per Resolution

At 1920x1080, the Ultra preset delivers an average of 181 FPS, which is the most demanding setting available and remains far above the 60 FPS threshold. The data shows no need to reduce settings at this resolution, as even the highest quality configuration maintains a frame rate that exceeds the refresh rate of most monitors.

At 2560x1440, the Ultra preset averages 117 FPS. This is the best visual quality setting that stays at or above 60 FPS, and it does so with a substantial 57 FPS margin. The Medium preset's minimum of 144 FPS confirms that even the lower settings have significant headroom, but Ultra is the recommended choice for maximum visual fidelity.

At 3840x2160, the Ultra preset averages 63 FPS, which is just barely above the 60 FPS playable threshold. This is the most demanding configuration tested, and the data shows it is playable but with a narrow 3 FPS margin. For users who prefer a larger safety margin, the High preset averages 78 FPS, providing 18 FPS of headroom above the threshold while maintaining high visual quality. The Ultra preset remains the best setting that achieves playable performance, but the margin is tight enough that users with displays that experience frame pacing issues may prefer High.
