# Doom: Intel Core Ultra 7 165H + AMD Radeon RX 7900M

The Intel Core Ultra 7 165H paired with the AMD Radeon RX 7900M delivers a formidable 1080p experience in Doom, where frame rates scale from 155 FPS at Ultra settings to 258 FPS at Low, positioning this combo in the 1226th spot out of 2930 tested configurations. At 1440p, the combination maintains smooth triple-digit performance across all settings, while 4K remains playable but demands careful settings selection to stay above 60 FPS. The data reveals a system where the GPU carries progressively more load as resolution climbs, but the CPU's 16 cores and 22 threads ensure headroom even at lower resolutions.

CPU Role

The Intel Core Ultra 7 165H is a mobile processor built on the Meteor Lake architecture, featuring 16 cores and 22 threads. Its base clock runs at 3.80 GHz with a boost clock of 5.00 GHz, and it carries 24 MB of shared L3 cache alongside 2 MB L2 per core and 112 KB L1 per core. The chip's TDP is rated at 28 watts, and it supports DDR5 memory over a dual-channel bus with 89.6 GB/s of bandwidth. This processor posts an average benchmark score of 34083, placing it in the 84th percentile among all CPUs tested.

In Doom, the CPU's role shifts depending on resolution. At 1080p Low settings, the combo reaches 258 FPS average, which suggests the processor is feeding frames efficiently without bottlenecking the GPU. The single-thread performance, measured at 1759 in Cinebench R23 single-core, is adequate for Doom's engine, which typically responds well to strong per-core performance. The multi-threaded score of 14551 in Cinebench R23 indicates that even if the game were to spawn background threads, the 22-thread capacity offers ample margin.

Compared to its nearest rivals, the Core Ultra 7 165H sits within a tight performance band. It trails the Intel Core Ultra 5 338H by a mere 0.3% in average benchmark score (33989 vs 34083), while leading the AMD EPYC 4244P and AMD Ryzen AI 7 350 by 0.4% each (both scoring 34220 and 34222 respectively, with negative deltas). The AMD Ryzen 7 3700X edges it out by 0.5% with a score of 34260. These sub-1% differences are negligible in real-world gaming, meaning the CPU's contribution to Doom's frame rates is essentially on par with these alternatives.

The PassMark integer math score of 89415 and floating-point score of 66273 provide context for the processor's arithmetic throughput, which matters for game logic and physics calculations. The data compression score of 291161 and encryption score of 17169 indicate robust general-purpose compute, though these are less directly relevant to Doom's rendering pipeline than the single-thread results.

Q: How much performance is lost going from 1080p to 4K at High settings?

A: The average FPS drops from 190 at 1080p to 123 at 1440p, then further to 67 at 4K. This represents a 65% reduction from 1080p to 4K, indicating the GPU becomes the primary bottleneck as pixel count increases.

Resolution Scaling

The measured FPS data shows a clear scaling pattern across resolutions. At 1080p High settings, the combo averages 190 FPS, which drops to 123 FPS at 1440p and 67 FPS at 4K. This translates to a 35% loss from 1080p to 1440p and a further 46% loss from 1440p to 4K. The scaling is consistent with a GPU-bound scenario, where the RX 7900M's rendering throughput determines the frame rate.

Low settings exhibit similar behavior: 258 FPS at 1080p, 167 FPS at 1440p, and 90 FPS at 4K. The relative drop from 1080p to 4K is 65%, matching the High setting pattern. Medium settings show 225 FPS at 1080p, 145 FPS at 1440p, and 79 FPS at 4K, with the 4K result including a minimum of 67 FPS and maximum of 91 FPS. Ultra settings produce the steepest curve: 155 FPS at 1080p, 100 FPS at 1440p, and 54 FPS at 4K.

These numbers reveal that the limiting component shifts with resolution. At 1080p, the high frame rates (155-258 FPS) suggest the CPU still has headroom, since even the weakest setting exceeds 150 FPS. As resolution increases to 4K, the GPU's workload grows exponentially, and the 54-90 FPS range indicates the RX 7900M becomes the constraining factor. The 4K Medium result (79 FPS average) with a 67 FPS minimum shows that the GPU can maintain playable performance, but the gap between Low and Ultra at 4K (36 FPS) is narrower than at 1080p (103 FPS), confirming GPU saturation.

How This Combo Ranks

This specific combination of Intel Core Ultra 7 165H and AMD Radeon RX 7900M ranks 1226th out of 2930 tested combos in Doom. This places it in the upper-middle tier of all configurations, roughly in the 58th percentile of tested pairings. The ranking reflects the balance between a strong mobile GPU and a capable mid-range processor, though it does not crack the top tier occupied by desktop flagship combos.

The fact that the combo ranks below the median of the top 50% suggests that Doom's performance is more sensitive to GPU capability than CPU choice, given that the RX 7900M's 94th percentile GPU ranking does not translate to an equally high combo ranking. The 1226th position implies that many combos with faster GPUs, even paired with weaker CPUs, achieve higher frame rates. Conversely, combos with this GPU but slower processors might still outperform this pairing if their GPUs are stronger overall.

The delta between the GPU's individual percentile (94th) and the combo's rank (58th percentile) indicates that the Core Ultra 7 165H, while competent in isolation, does not boost the pairing into elite territory. In Doom, where frame rates at 1080p reach 258 FPS, the CPU is not a limiting factor, so the combo's rank is primarily driven by the GPU's absolute performance relative to other tested graphics cards.

Its compute capabilities include 38.52 TFLOPS FP32 and 77.05 TFLOPS FP16, with pixel and texture rates of 401.3 GPixel/s and 601.9 GTexel/s respectively. The TDP is rated at 180 W, and it connects via PCIe 4.0 x16.

In Doom, the RX 7900M demonstrates its strength through consistent frame delivery. At 1080p, the GPU pushes beyond 200 FPS on all settings except Ultra, where it still manages 155 FPS. The 4K results show the GPU's limits: 54 FPS at Ultra, 67 FPS at High, 79 FPS at Medium, and 90 FPS at Low. The 16 GB VRAM capacity is more than sufficient for Doom's textures, as the game's release date precedes larger VRAM requirements, so memory bandwidth is not a constraint.

The GPU's benchmark scores corroborate its gaming performance. In 3DMark Steel Nomad DX12, it scores 4201, while Geekbench OpenCL and Vulkan scores reach 129499 and 158760 respectively. These place the RX 7900M in the 94th percentile of all GPUs, with an average benchmark score of 97487. Against its rivals, it leads the AMD Radeon Pro VII by 0.4%, trails the NVIDIA Quadro RTX 6000 by 4.3%, and exceeds the AMD Radeon Instinct MI60 and NVIDIA RTX A4500 by 5.4% and 6.3% respectively. The positive delta against the Pro VII and the negative delta against the Quadro RTX 6000 indicate that the RX 7900M sits in a competitive mid-to-high range of GPU performance.
