AMD Ryzen AI 9 PRO 465 vs Intel Core Ultra 7 255H Comparison

Head-to-Head Benchmarks

The recorded data shows a clear split in workload preferences between the AMD Ryzen AI 9 PRO 465 and the Intel Core Ultra 7 255H. Across the 11 shared PassMark tests, Intel takes 6 wins and AMD takes 5, but the margins tell a more detailed story.

AMD's largest victory comes in integer math, where it scores 107,173 against Intel's 77,975. That is a 37.4% lead, the biggest delta in either direction across the entire benchmark set. Data compression also favors AMD heavily: 385,174 versus 298,850, a 28.9% advantage. AMD also wins random string sorting by 13.3% (40,860 versus 36,058), extended instructions by 11.3% (26,441 versus 23,755), and multithread by a narrow 2.5% (31,485 versus 30,703).

Intel's wins are concentrated in different domains. The most dramatic is find prime numbers, where Intel scores 303 against AMD's 126, a 58.4% advantage. Floating point math also goes firmly to Intel: 98,796 versus 66,824, a 32.4% lead. Physics follows at 22.5% in Intel's favor (2,254 versus 1,747). Data encryption shows Intel ahead by 17.5% (23,395 versus 19,308). Single-thread performance is close but favors Intel: 4,317 versus 4,168, a 3.5% edge.

The multithread result deserves attention because it is nearly a tie despite the different core counts. AMD's 10 cores with 20 threads edge out Intel's 16 cores with 16 threads by only 2.5%. Meanwhile, the average benchmark scores in the database place these chips far apart in overall standing. AMD's average score is 62,498, which ranks in the 93rd percentile among all CPUs. Intel's average is 33,537, ranking in the 83rd percentile. However, the nearest-rival data for AMD lists the Intel Core Ultra 7 255HX at 62,738 (0.4% ahead), while Intel's nearest rival is the AMD Ryzen 5 240 at 33,542 (essentially a 0.0% delta). This discrepancy suggests the average-score metric is heavily influenced by the different benchmark suites recorded for each processor, so the head-to-head PassMark results are the more reliable comparison for these two specific chips.

Architecture Differences

The two processors come from different design philosophies. AMD uses a Zen 5 architecture on a 4 nm TSMC process, with the codename Gorgon Point and a generation label of Ryzen AI PRO 400. The die size is 233 mm². Intel uses Arrow Lake architecture on a 3 nm TSMC process, with the codename Arrow Lake-H and a generation label of Ultra 7. Intel does not record a die size for this part.

Core and thread configurations differ substantially. AMD provides 10 cores and 20 threads, relying on simultaneous multithreading. Intel provides 16 cores and 16 threads, with no SMT. Both have a base clock of 2.00 GHz, but Intel's boost clock reaches 5.10 GHz versus AMD's 5.00 GHz. Both parts carry a 28 W TDP and are mobile segments with active production status.

Cache hierarchies are structured differently. AMD allocates 80 KB of L1 per core, 1 MB of L2 per core, and 16 MB of shared L3. Intel allocates 192 KB of L1 per core, 3 MB of L2 per core, and 24 MB of shared L3. The larger per-core caches on Intel may help explain its strong single-thread and prime-number results, while AMD's larger thread count and smaller per-core cache still delivers a multithread win.

Memory support is similar on paper: both use DDR5 and LPDDR5X over a dual-channel bus. However, Intel lists a higher memory bandwidth of 102.4 GB/s against AMD's 89.6 GB/s. Intel also supports ECC memory, while AMD does not. PCIe connectivity differs as well: AMD offers Gen 4 with 16 CPU lanes, while Intel offers Gen 5 with 20 CPU lanes.

The integrated graphics differ in naming and likely capability. AMD pairs with the Radeon 890M, while Intel pairs with Arc Graphics 140T. The database does not include graphics benchmarks for either, so the comparison stops at the specification level. Socket types also diverge: AMD uses FP8, Intel uses BGA 2049. Release dates place Intel earlier at January 2025, with AMD arriving in January 2026.

Where Each One Wins

AMD Ryzen AI 9 PRO 465 wins in integer-heavy and compression-heavy tasks. The 37.4% lead in integer math and 28.9% lead in data compression point to workloads like database operations, file archiving, and general productivity where integer throughput matters. The 11.3% edge in extended instructions and 13.3% edge in random string sorting reinforce this pattern. The multithread win, while small, suggests AMD's 20 threads extract slightly more parallelism from well-threaded applications.

Intel Core Ultra 7 255H wins in floating-point and prime-number workloads. The 32.4% lead in floating point math and the massive 58.4% lead in prime-number finding indicate a strong FPU and possibly better branch handling. Physics simulation, which often depends on floating-point precision, follows at 22.5%. Data encryption favors Intel by 17.5%, which may reflect the larger L2 cache or the higher boost clock. Single-thread performance is Intel's by 3.5%, making it the better choice for lightly threaded applications that rely on one core's peak speed.

For users prioritizing multitasking and integer throughput, the AMD part shows a measurable advantage. For users prioritizing floating-point calculations, prime-number search, encryption, or single-thread responsiveness, the Intel part holds the edge. The two processors are effectively tied in multithread performance, so the deciding factor in that category is workload-specific rather than a general throughput gap.

The Verdict

The data indicates two different performance profiles with no single dominant chip. AMD Ryzen AI 9 PRO 465 wins 5 of the 11 head-to-head benchmarks, including the only multithread test and the largest single delta in integer math. Intel Core Ultra 7 255H wins 6 benchmarks, including the largest single delta in prime-number finding and a clear lead in floating-point math.

Intel's higher memory bandwidth (102.4 GB/s versus 89.6 GB/s), larger caches, and higher boost clock align with its wins in physics, encryption, prime numbers, and single-thread tests. AMD's extra threads and smaller die size (233 mm² versus no recorded size for Intel) align with its wins in integer math, compression, extended instructions, and multithread.

The database places AMD in the 93rd percentile and Intel in the 83rd percentile, but the direct comparison shows a near tie in multithread performance and a 3.5% Intel edge in single-thread. Users whose workloads rely on integer arithmetic, data compression, or heavily threaded productivity should favor the AMD part. Users whose workloads rely on floating-point calculations, encryption, prime-number searches, or single-thread responsiveness should favor the Intel part. Neither chip delivers a decisive overall victory; the choice depends entirely on the specific task mix.
