AMD Ryzen AI 9 365 vs Intel Core Ultra 9 275HX Comparison

Head-to-Head Benchmarks

The recorded data presents a decisive picture. The Intel Core Ultra 9 275HX wins every single head-to-head benchmark in the database. The AMD Ryzen AI 9 365 does not secure a single victory across the seventeen compared tests. The margin of victory varies significantly by workload, ranging from a relatively modest single-core edge to overwhelming multi-threaded leads.

The largest gap appears in the PassMark find prime numbers test. Intel scores 448 against AMD's 117, a delta of 73.9 percent. This points to a substantial advantage in integer-heavy, latency-sensitive mathematical workloads. Floating point math shows a similarly lopsided result, with Intel at 191186 versus 62802, a 67.2 percent deficit for the AMD part. Data encryption also swings heavily toward Intel, 47112 to 18297, a 61.2 percent gap. These three results indicate that the Intel chip has a commanding lead in raw computational throughput.

Multi-core rendering benchmarks reinforce that conclusion. In Cinebench R23 multi-core, the Intel part scores 35589, while the AMD chip manages 18698, a 47.5 percent difference. The older Cinebench R15 multi-core test shows 5619.5 for Intel against 2842 for AMD, a 49.4 percent delta. Geekbench multi-core lands at 20795 for Intel and 13760 for AMD, a 33.8 percent advantage. The PassMark multi-thread score follows the pattern, 55759 versus 29467, a 47.2 percent gap. These figures confirm that the Core Ultra 9 275HX delivers roughly half again as much multi-threaded performance in several tests.

Single-core results are closer but still favor Intel. Cinebench R23 single-core shows 2204 for Intel versus 1992 for AMD, a 9.6 percent delta. Geekbench single-core is 2458 versus 2253, an 8.3 percent gap. Cinebench R15 single-core is 334 versus 303, a 9.3 percent difference. PassMark single-thread is 4713 versus 3841, an 18.5 percent delta. The Intel chip holds a clear single-thread lead, though it is far narrower than the multi-core margins.

Other PassMark subtests continue the trend. Data compression favors Intel 608381 to 354510, a 41.7 percent delta. Extended instructions go to Intel 47016 to 25113, a 46.6 percent gap. Integer math is 155218 versus 101831, a 34.4 percent delta. Physics lands at 3338 versus 1704, a 49 percent difference. Random string sorting is 74320 versus 39447, a 46.9 percent gap. The Intel chip leads by roughly a third to a half across these varied workloads.

The average benchmark score in the database reflects the overall gap: Intel sits at 67469, while AMD averages 40048. That puts the AMD chip at the 87th percentile of all CPUs, while the Intel chip reaches the 94th percentile.

The Verdict

The data points to the Intel Core Ultra 9 275HX as the stronger performer in every measured category. It wins all seventeen head-to-head benchmarks, with multi-core leads ranging from 33.8 percent to 73.9 percent. Its average benchmark score of 67469 places it at the 94th percentile, with nearest rivals in the workstation and server class. The 24-core, 24-thread configuration, larger caches, higher memory bandwidth, and faster clocks all support this result.

The AMD Ryzen AI 9 365 is the lower-power option, with a 28 watt TDP against Intel's 55 watts. It also has a smaller die and a different core mix. Its average benchmark score of 40048 places it at the 87th percentile, with nearest rivals in the mainstream desktop and mobile range. The single-core gap to Intel is modest, between 8.3 and 18.5 percent depending on the test, but the multi-core gap is substantial.

For workloads that depend on multi-threaded throughput, the Intel chip is clearly the better choice according to the measured data. For single-threaded tasks, the Intel chip still leads, but the margin is smaller. The AMD chip's advantages lie outside the benchmark results, namely a much lower TDP and support for LPDDR5X memory. Buyers prioritizing raw performance should look to Intel. Buyers prioritizing power efficiency should consider AMD. The benchmark data itself offers no argument for the AMD chip on performance grounds alone.
