Doom

The Intel Core Ultra 7 265 paired with the NVIDIA GeForce RTX 5080 delivers overwhelming performance in Doom, with every tested resolution and preset combination clearing the 60 FPS playable threshold by a substantial margin. Measured data shows this combo ranks 175th out of 3,712 tested system configurations for this title, placing it in the top 5% of all combos. The system produces triple-digit frame rates even at 4K with Ultra settings, and at 1080p it approaches the refresh rate limits of most high-end monitors.

Measured FPS Breakdown

At 1920x1080, the combo produces extraordinary frame rates that will saturate virtually any display. With Low settings, the average FPS reaches 416, while Medium settings deliver 363 FPS average with a minimum of 308 and maximum of 417. High settings still produce an average of 306 FPS, and even the most demanding Ultra preset maintains an average of 250 FPS. These figures indicate the system is heavily CPU-limited at this resolution, as the GPU has enormous headroom to spare.

Moving to 2560x1440, performance remains exceptionally high but begins to show more GPU involvement. Low settings average 269 FPS, Medium settings average 235 FPS with a minimum of 199 and maximum of 270, and High settings average 198 FPS. Ultra settings at 1440p still deliver a robust 162 FPS average. The scaling from 1080p to 1440p shows roughly a 35-40% reduction in frame rates across presets, which is typical for a resolution increase that doubles pixel count.

At 3840x2160, the RTX 5080 finally starts to work harder, though the results remain far above playable thresholds. Low settings average 146 FPS, Medium settings average 127 FPS with a minimum of 108 and maximum of 146, and High settings average 107 FPS. Ultra settings at 4K produce an 88 FPS average, which is still comfortably above the 60 FPS threshold. The performance drop from 1440p to 4K is significant — approximately 45-50% across all presets — reflecting the 2.25x pixel increase that 4K represents over 1440p.

The Medium preset is the only one with complete min/max data across all resolutions. At 1080p Medium, the spread between minimum and maximum is 308 to 417 FPS, a 109 FPS range. At 1440p Medium, the spread narrows somewhat to 199 to 270 FPS, a 71 FPS range. At 4K Medium, the spread is 108 to 146 FPS, a 38 FPS range. This tightening of the frame time distribution as resolution increases indicates that GPU workload becomes more consistent at higher resolutions, reducing the variance caused by CPU-driven frame pacing.

CPU and GPU Roles

The data reveals a clear division of labor between the Core Ultra 7 265 and the RTX 5080 across the resolution spectrum. At 1080p, the system is almost certainly CPU-bound, as evidenced by the massive frame rates that exceed 400 FPS on Low settings. The Core Ultra 7 265's 20 cores and 20 threads, with a boost clock of 5.30 GHz, provide the single-thread performance necessary to feed the GPU at these extreme rates. The CPU's Cinebench R23 single-core score of 5,960 and multi-core score of 42,216 indicate strong per-thread performance that Doom's engine can leverage effectively.

At 1440p, the balance shifts slightly toward the GPU, but the CPU remains a significant factor. The frame rate drop from 1080p to 1440p is roughly 35-40%, which aligns with the increased pixel workload. However, the fact that 1440p Ultra still achieves 162 FPS suggests the CPU is still keeping pace with the GPU's output. The RTX 5080's 56.28 TFLOPS of FP32 compute and 960.0 GB/s of memory bandwidth provide ample raw throughput for this resolution.

At 4K, the GPU becomes the dominant constraint. The frame rate drops by roughly 45-50% from 1440p, and the absolute numbers (88-146 FPS depending on preset) indicate that the RTX 5080 is now the limiting factor. The GPU's 16 GB of GDDR7 memory on a 256-bit bus provides 960.0 GB/s of bandwidth, which is sufficient for 4K textures but still represents the primary bottleneck at this resolution. The CPU's role diminishes at 4K, as the GPU takes longer to render each frame, giving the CPU ample time to prepare the next frame.

The scaling between presets also reveals component roles. At 1080p, moving from Low to Ultra reduces frame rates from 416 to 250 FPS, a 40% drop. At 4K, the same preset change reduces frame rates from 146 to 88 FPS, a 40% drop as well. This consistent percentage reduction across resolutions suggests that the rendering workload scales linearly with preset quality, and that neither component creates a disproportionate bottleneck at any resolution.

How This Combo Ranks

The combination of Intel Core Ultra 7 265 and NVIDIA GeForce RTX 5080 achieves a rank of 175 out of 3,712 tested combos for Doom. This places the system in the 95th percentile of all tested configurations, indicating that only about 174 other system combinations perform better in this specific title. The ranking reflects the strong synergy between the CPU's high single-thread performance and the GPU's massive rasterization throughput.

The rank is particularly impressive given that the RTX 5080 sits in the 87th percentile among all GPUs, while the Core Ultra 7 265 sits in the 93rd percentile among all CPUs. The combination of two top-decile components produces a system that ranks in the top 5% for this game specifically. The ranking suggests that Doom's id Tech engine scales well with both high-core-count CPUs and high-bandwidth GPUs, allowing this system to leverage its full potential.

The data shows that the system's rank is driven primarily by its ability to maintain extremely high frame rates at all resolutions. Even at 4K Ultra, where the system is most GPU-bound, the 88 FPS average is far above what most systems can achieve in this title. The rank of 175 indicates that there is a small group of more powerful configurations — likely those with higher-end GPUs like the RTX 5090 or RX 7900 XTX — that can push frame rates even higher, but this combo remains in the elite tier.

Similar Performance Alternatives

For the CPU side, the nearest rivals to the Core Ultra 7 265 are all server-class processors with similar average benchmark scores. The AMD EPYC 4464P has an average score of 64,823, which is 0.3% lower than the Core Ultra 7 265's average. The Intel Core Ultra 7 265F is nearly identical, with a score of 64,438 (0.3% higher). The AMD EPYC 7343 scores 64,202 (0.7% higher), and the AMD EPYC 9124 scores 65,104 (0.7% lower). These alternatives would provide similar CPU-bound performance in Doom, though the EPYC chips are designed for data center workloads rather than gaming.

On the GPU side, the RTX 5080's nearest rivals show interesting alternatives. The AMD Radeon 8060S has an average score of 55,757, which is 0.6% lower than the RTX 5080's average. The AMD Radeon RX 6750 GRE 12 GB scores 55,698 (0.7% lower), and the AMD Radeon Pro W5700X scores 54,828 (2.3% lower). The AMD Radeon RX 9070 GRE scores 57,367, which is 2.2% higher than the RTX 5080. These GPUs would deliver similar frame rates in Doom, with the RX 9070 GRE potentially offering slightly higher performance in GPU-bound scenarios.

For a system that behaves similarly to this combo, pairing the Core Ultra 7 265F (which is essentially the same chip) with either the RX 9070 GRE or the Radeon 8060S would produce results within 2-3% of the measured performance. The EPYC processors, while having similar synthetic benchmark scores, may not translate identically to gaming performance due to their different memory architectures and core configurations.

The Verdict

This system can absolutely run Doom — the question is not whether it can hit 60 FPS, but how far beyond that threshold it can go. The verdict data confirms that all four settings presets (Low, Medium, High, Ultra) are playable at every tested resolution. At 1920x1080, the best settings preset is Ultra with an average of 250 FPS. At 2560x1440, Ultra delivers 162 FPS on average. At 3840x2160, Ultra still maintains an 88 FPS average.

The 4K Ultra result of 88 FPS is particularly noteworthy because it clears the 60 FPS threshold by 47%, providing headroom for frame rate dips during intense combat sequences. The minimum measured FPS across all configurations is 108 at 4K Medium, which means the system never drops below the playable threshold in any measured scenario.

For players with high-refresh-rate monitors, the 1440p and 1080p results are exceptional. At 1440p, even Ultra settings exceed 160 FPS, which pairs well with 144Hz or 165Hz displays. At 1080p, the system can drive 360Hz and even 400Hz monitors in less demanding presets, though the Ultra preset's 250 FPS average is more realistic for sustained gameplay.

The RTX 5080's 16 GB of GDDR7 memory ensures that even the most texture-heavy mods or future Doom updates won't exceed VRAM capacity. The Core Ultra 7 265's 30 MB of L3 cache and dual-channel DDR5 support provide sufficient memory bandwidth for the CPU to feed the GPU at all resolutions. This system is not just playable — it is exceptionally well-suited for competitive play at high refresh rates, with enough overhead to handle any settings configuration the game offers.
