Architecture Differences

The AMD Ryzen AI 9 365 uses the Zen 5 architecture under the Strix Point codename, built on a 4 nm process at TSMC. The die measures 233 mm². Its generation is listed as Ryzen AI 300, combining Zen 5 and Zen 5c cores. The processor is designed for the mobile segment and uses the AMD Socket FP8.

The Intel Core Ultra 7 265K belongs to the Core Ultra Series 2, built on the Arrow Lake architecture with the codename Arrow Lake-S. It uses a 3 nm process at TSMC, packs 17,800 million transistors on a 243 mm² die, and fits into the Intel Socket 1851 as a desktop part.

Cache hierarchies diverge significantly. The AMD chip provides 80 KB of L1 per core plus 1 MB of L2 per core, with a 16 MB L3 pool. The Intel chip doubles down with 192 KB of L1 per core, 3 MB of L2 per core, and a 30 MB shared L3. These differences directly impact how each processor feeds its execution units during cache-sensitive workloads.

Memory support also separates the two. The AMD Ryzen AI 9 365 accepts both DDR5 and LPDDR5X, making it flexible for thin-and-light mobile designs. The Intel Core Ultra 7 265K supports only DDR5 but adds ECC memory capability, a feature absent on the AMD side. Memory bandwidth measures 89.6 GB/s for the AMD chip versus 102.4 GB/s for the Intel part, a 12.8 GB/s advantage for Intel.

PCIe connectivity differs as well. The AMD processor exposes Gen 4 with 16 CPU lanes, while Intel provides Gen 5 with 20 CPU lanes. Integrated graphics also contrast: the AMD chip carries the Radeon 880M, whereas Intel includes Arc Xe-LPG Graphics with 64 execution units.

Power characteristics are not comparable in scale. The AMD Ryzen AI 9 365 has a 28 W TDP, while the Intel Core Ultra 7 265K draws 125 W. The Intel chip is multiplier-unlocked for overclocking; the AMD chip is not. Release dates differ by roughly four months, with AMD arriving 2024-06-30 and Intel following 2024-10-23.

The Verdict

The recorded data shows a clear separation in performance class. The Intel Core Ultra 7 265K wins all 17 head-to-head benchmark comparisons against the AMD Ryzen AI 9 365. The average benchmark score for Intel stands at 70879, which is 30831 points higher than AMD's 40048, a difference of 77 percent. The Intel processor also holds the 94th percentile among all CPUs, while the AMD chip sits at the 87th percentile.

The Intel part is the choice for desktop workloads where raw throughput matters. Its 20 cores, higher clocks, and larger cache produce decisive wins in every measured category. The AMD Ryzen AI 9 365, with its 28 W TDP and mobile socket, targets portable systems where power efficiency takes priority over absolute performance. The data confirms this split: the Intel chip consumes 125 W and delivers desktop-class results, while the AMD chip operates at 28 W and still posts competitive scores for its class.

Single-core performance is the narrowest gap between the two. In Cinebench R23 single-core, Intel leads by only 1.4 percent. The AMD chip's boost clock of 5.00 GHz versus Intel's 5.50 GHz explains part of this margin. For buyers who need maximum multi-threaded performance in a desktop chassis, the Intel Core Ultra 7 265K is the data-supported pick. For users who require a mobile processor with modest power draw, the AMD Ryzen AI 9 365 remains a relevant option despite its lower benchmark scores.
