# Doom Performance Analysis: Intel Core Ultra 7 265 + NVIDIA GeForce RTX 3080 Ti

This combo delivers strong frame rates across all resolutions in Doom, with the RTX 3080 Ti clearly carrying the load at 4K while the Core Ultra 7 265 ensures headroom at lower resolutions. The data shows a system that scales predictably from 1080p to 4K, with the GPU becoming the primary constraint as pixel count rises.

Resolution Scaling

The measured FPS reveals a clear pattern of GPU-bound scaling. At 1080p High settings, this combo averages 230 FPS. Moving to 1440p High drops that to 149 FPS, a reduction of roughly 35%. At 4K High, the average falls to 81 FPS, which is about 46% below the 1440p result and 65% below 1080p. This steep decline is typical of a game where the GPU's pixel throughput becomes the limiting factor at higher resolutions.

The scaling curve from Low to Ultra settings tells the same story. At 1080p Low, the system hits 312 FPS — a massive figure that indicates the CPU is not bottlenecking even at extreme frame rates. At 1440p Low, the average drops to 202 FPS, and at 4K Low it's 109 FPS. The delta between Low and Ultra at each resolution is significant: 124 FPS at 1080p (312 vs 188), 80 FPS at 1440p (202 vs 122), and 43 FPS at 4K (109 vs 66). The shrinking gap at higher resolutions confirms that the GPU is the limiting component — at 4K, even dropping to Low settings cannot fully compensate for the pixel load.

The Medium settings data provides a useful midpoint with min/max readings. At 1080p Medium, the average is 272 FPS with a minimum of 231 and maximum of 313. At 1440p Medium, the average is 176 FPS with min 150 and max 202. At 4K Medium, the average is 95 FPS with min 81 and max 110. The min-to-max spread narrows as resolution increases, indicating more consistent frame pacing at higher resolutions where the GPU is fully saturated.

GPU Role

The NVIDIA GeForce RTX 3080 Ti is the dominant player in this combo for Doom. Its 12 GB of GDDR6X memory across a 384-bit bus provides 912.4 GB/s of bandwidth, which is ample for this 2016 title even at 4K Ultra. The card's GA102 chip, built on Samsung's 8 nm process, contains 28,300 million transistors on a 628 mm² die. These specifications translate into a benchmark percentile of 83 vs all GPUs, with an average benchmark score of 41,187.

The RTX 3080 Ti's clock behavior matters here. With a base clock of 1365 MHz and boost of 1665 MHz, the card sustains high throughput in a game like Doom that responds well to raw shading power. The 10,240 shading units, 320 TMUs, and 112 ROPs deliver a pixel rate of 186.5 GPixel/s and texture rate of 532.8 GTexel/s. These figures explain why the card manages 81 FPS at 4K High — it has the raw fill rate to handle demanding scenes without relying on upscaling or frame generation.

The GPU's nearest rivals in the benchmark database include the AMD Radeon Pro 5300 (0.8% higher average score) and the NVIDIA GeForce RTX 5070 (2% lower average score). The RTX 3080 Ti sits between these in overall compute, but in Doom specifically, the 12 GB VRAM capacity is more than sufficient — the game does not appear to hit memory limits at any tested setting, as evidenced by the smooth scaling from Low to Ultra at each resolution.

How This Combo Ranks

This pairing ranks 963rd out of 3,712 tested combos in Doom, placing it in the top 26% of all systems tested. That percentile position is respectable for a mid-generation GPU paired with a current-generation CPU. The rank reflects the RTX 3080 Ti's strong absolute performance in this title, even though newer GPUs may surpass it in synthetic benchmarks.

The CPU's own benchmark standing is notably high — the Core Ultra 7 265 sits at the 93rd percentile vs all CPUs with an average benchmark score of 64,640. Its nearest rivals include the AMD EPYC 4464P (0.3% lower score), Intel Core Ultra 7 265F (0.3% higher), AMD EPYC 7343 (0.7% higher), and AMD EPYC 9124 (0.7% lower). This CPU is clearly not the limiting factor in Doom, as its strong single-thread performance ensures the GPU can run at full utilization.

The gap between the combo's rank (top 26%) and the GPU's percentile (83) suggests that while the RTX 3080 Ti is a capable card, other components in some competing systems — likely faster GPUs — push those combos higher. For a game like Doom that scales well with GPU power, the combo rank is primarily driven by the graphics card, and the 3080 Ti's position at the 83rd GPU percentile aligns with a top-quartile combo ranking.

FAQ

The complete dataset shows a consistent pattern: each resolution step down (from 4K to 1440p to 1080p) yields approximately a 45-50% increase in average FPS at equivalent settings. The High settings at 1080p (230 FPS) exceed the Low settings at 1440p (202 FPS), demonstrating that resolution has a larger impact on performance than quality presets in this title.

CPU Role

The Intel Core Ultra 7 265 plays a supporting but essential role in this combo. With 20 cores and 20 threads running at a base clock of 2.40 GHz and boost up to 5.30 GHz, this Arrow Lake-S architecture CPU provides ample processing headroom for Doom's game logic and physics. The 30 MB of shared L3 cache and 3 MB L2 per core help maintain low latency access to frequently used data, which matters for frame pacing in a fast-paced FPS.

The CPU's benchmark results indicate strong multi-threaded capability: Cinebench R23 multi-core scores 42,216, while single-core reaches 5,960. PassMark single-thread performance is 4,689, and multi-thread reaches 49,682. These figures place the CPU at the 93rd percentile vs all CPUs, meaning it outperforms the vast majority of processors in the database. The data compression score of 522,983 and floating-point math score of 172,776 further demonstrate the CPU's capability in varied workloads.

In Doom specifically, the CPU is not the bottleneck at any resolution. Evidence: at 1080p Low, the system achieves 312 FPS, which is near the practical ceiling for many display refresh rates. Even at 4K Ultra, where the GPU is clearly stressed (66 FPS), the CPU has enough headroom to feed the GPU without causing frame drops. The CPU's 65 W TDP and 3 nm process node (TSMC) make it an efficient partner for the 350 W RTX 3080 Ti, though the combined power draw would require a robust power supply — the GPU alone suggests a 750 W PSU.

The Core Ultra 7 265's nearest rivals in the database are all server-class EPYC processors, which underscores its strong multi-threaded performance relative to desktop CPUs. However, for gaming, the single-thread score of 5,960 in Cinebench R23 is the more relevant metric, and it is more than sufficient to keep the RTX 3080 Ti fed in Doom's engine. The CPU's 20 lanes of PCIe Gen 5 connectivity ensure the GPU's PCIe 4.0 x16 interface operates without bandwidth constraints.
