Architecture Differences

Both processors share the Zen 5 architecture and TSMC's 4 nm process node, but they diverge in nearly every other structural detail. The Ryzen AI 9 PRO 465 belongs to the Gorgon Point family under the Ryzen AI PRO 400 generation, which combines Zen 5 and Zen 5c cores. It offers 10 cores and 20 threads. The Max PRO 385 comes from the Strix Halo line under the Ryzen AI Max PRO generation, with 8 cores and 16 threads. Both boost to 5.00 GHz, but the base clocks differ substantially: the 465 operates at 2.00 GHz, while the Max PRO 385 starts at 3.60 GHz.

Cache configuration separates the two clearly. The 465 has 16 MB of L3 cache, while the Max PRO 385 carries 32 MB shared L3. Both use 80 KB L1 per core and 1 MB L2 per core. The die size for the 465 is recorded at 233 mm², while the Max PRO 385's die size is not listed in the database.

Memory architecture favors the Max PRO 385. It supports LPDDR5X over a quad-channel bus with 256.0 GB/s bandwidth. The 465 supports DDR5 and LPDDR5X over a dual-channel bus with 89.6 GB/s. The Max PRO 385 also supports ECC memory, while the 465 does not. Both use PCIe Gen 4 with 16 CPU lanes. The sockets differ as well: the 465 uses AMD Socket FP8, and the Max PRO 385 uses AMD Socket FP11.

The integrated graphics differ between the two. The 465 carries the Radeon 890M, while the Max PRO 385 uses the Radeon 8050S. Both are marked as mobile market segment parts with active production status. The 465's release date is recorded as 2026-01-04, while the Max PRO 385's release date is 2025-01-05. Neither processor has an unlocked multiplier. The part numbers are 100-000001862 for the 465 and 100-000001422 for the Max PRO 385.

The TDP ratings show a major power envelope difference. The 465 is rated at 28 W, while the Max PRO 385 is rated at 55 W. This explains the base clock disparity and partially accounts for the Max PRO 385's higher bandwidth and larger cache allocation.

Head-to-Head Benchmarks

The largest single benchmark gap in the comparison belongs to the Max PRO 385 in the find prime numbers test. It scores 157 against the 465's 126, a 19.7% advantage. This test is sensitive to core efficiency and cache behavior, and the Max PRO 385's 32 MB shared L3 likely contributes to the result. The extended instructions test shows the second-largest gap, with the Max PRO 385 leading 31442 to 26441, a 15.9% margin. This indicates the Max PRO 385 executes AVX-style workloads more efficiently despite having fewer cores.

Floating-point math gives the Max PRO 385 a 4% lead, 69580 versus 66824. The multithread score adds a 1.8% win for the Max PRO 385 at 32075 versus 31485. These results align with the Max PRO 385's higher base clock and larger cache, which help in sustained parallel loads.

The 465's wins are smaller in magnitude but more numerous. Its best margin comes in single-thread performance at 4.3%, with scores of 4168 versus 3995. The physics test shows a 2.1% lead at 1747 versus 1711. Integer math gives the 465 a 2% edge at 107173 versus 105056. Data encryption shows a 1.7% lead at 19308 versus 18978, and data compression follows at 1.5% with 385174 versus 379448. The random string sorting result is nearly a tie, with the 465 ahead by only 0.2% at 40860 versus 40784.

In the PassMark multithread test, the Max PRO 385 wins by 1.8%, but the 465 wins the single-thread test by 4.3%. Both processors deliver a boost clock of 5.00 GHz, so the single-thread gap likely comes from the 465's two additional cores and its Zen 5c configuration, which can allocate lighter threads more efficiently. The Cinebench results recorded only for the Max PRO 385 show a multicore score of 28424 in R23 and 11938 in R20, with single-core scores of 4012 and 1685 respectively. These Cinebench figures are not directly comparable to the PassMark scores, but they confirm the Max PRO 385's strong multi-threaded rendering performance.

The Verdict

The data indicates two different design philosophies. The Ryzen AI 9 PRO 465 is the higher-ranked part overall, with a 93rd percentile placement against all CPUs and an average benchmark score of 62498. It wins the majority of head-to-head tests and holds a clear single-thread advantage. Its 28 W TDP, 10 cores, and 20 threads make it suitable for workloads that alternate between light and heavy loads, where the Zen 5c cores can handle background tasks while the full Zen 5 cores handle active work.

The Ryzen AI Max PRO 385 ranks at the 88th percentile with an average score of 43326. Its nearest rival comparison shows it nearly matches the Ryzen AI 9 465, with a delta of -0.2% against an average score of 43431. The Max PRO 385 wins the tests that matter for heavy compute: extended instructions, prime number calculation, floating-point math, and overall multithreading. Its 55 W TDP, quad-channel LPDDR5X memory at 256.0 GB/s, and 32 MB shared L3 cache position it for sustained, memory-hungry parallel tasks. ECC memory support adds another point in its favor for data integrity-sensitive applications.

For single-threaded responsiveness, integer-heavy work, and general productivity, the 465 delivers more wins at a lower power envelope. For floating-point, SIMD, and heavily parallel workloads where the larger cache and memory bandwidth come into play, the Max PRO 385 is the stronger option. The choice rests on whether the workload favors the 465's core count and single-thread speed or the Max PRO 385's cache, bandwidth, and instruction throughput.
