AMD Ryzen AI Max+ PRO 495 vs AMD Ryzen Embedded 8645HS Comparison

The AMD Ryzen AI Max+ PRO 495 and AMD Ryzen Embedded 8645HS are both active mobile AMD processors built on a 4 nm TSMC process, but they are positioned at opposite ends of the specification sheet. The database records no populated benchmark scores for either part: the average benchmark score is 0 for both, and both entries sit at the 50th percentile against all CPUs. The head-to-head benchmark list for this pair is empty, and the win count is 0 for each processor. This leaves the recorded specifications as the only basis for comparison, and they show two very different designs: a 16-core, 32-thread Zen 5 part with 64 MB of L3 cache against a 6-core, 12-thread Zen 4 part with 16 MB of shared L3.

Head-to-Head Benchmarks

The recorded head-to-head results for this pairing contain no benchmark entries. With no recorded wins for either processor, there is no measured performance delta in the database. The Ryzen AI Max+ PRO 495 leads with 16 cores and 32 threads versus 6 cores and 12 threads. Its L3 cache is 64 MB, while the Embedded 8645HS has 16 MB shared L3. Memory bandwidth is 273.1 GB/s on a quad-channel LPDDR5X bus for the AI Max+ PRO 495, compared with 89.6 GB/s on a dual-channel DDR5 bus for the Embedded 8645HS. The AI Max+ PRO 495 also has the higher boost clock, 5.20 versus 5.00, and a Radeon 8065S integrated GPU against a Radeon 760M.

The Ryzen Embedded 8645HS has its own specification wins. Its base clock is 4.30, above the 3.10 base clock of the AI Max+ PRO 495. Its TDP is 45, below the 55 TDP of the AI Max+ PRO 495. It also provides 20 CPU-only PCIe Gen 4 lanes, while the AI Max+ PRO 495 provides 16 CPU-only PCIe Gen 4 lanes. The database also lists no nearest rivals for either processor, so no external comparison points are available.

Architecture Differences

Both processors use a 4 nm process at TSMC, but the internal designs differ. The AI Max+ PRO 495 carries the codename Gorgon Halo and belongs to the Ryzen AI Max+ PRO generation built on Zen 5.

The AI Max+ PRO 495 uses AMD Socket FP11, while the Embedded 8645HS uses AMD Socket FP8.

The die and cache structures are distinct. The AI Max+ PRO 495 lists a die size of 2x 70.6 mm², with no transistor count recorded. The Embedded 8645HS lists a die size of 178 mm² and a transistor count of 25,000 million. Per core, the AI Max+ PRO 495 has 80 KB of L1 cache and 1 MB of L2 cache. The Embedded 8645HS has 64 KB of L1 cache and 1 MB of L2 cache. The L3 cache is 64 MB on the AI Max+ PRO 495 and 16 MB shared on the Embedded 8645HS.

Memory architecture is another major split. The AI Max+ PRO 495 supports LPDDR5X memory on a quad-channel bus with 273.1 GB/s of bandwidth. The Embedded 8645HS supports DDR5 memory on a dual-channel bus with 89.6 GB/s. Both processors list ECC memory support. Integrated graphics also differ: the AI Max+ PRO 495 has a Radeon 8065S, and the Embedded 8645HS has a Radeon 760M. Both are mobile parts in active production, and both have locked multipliers.

The remaining architecture differences are in I/O, power, and release timing. The AI Max+ PRO 495 has PCIe Gen 4 with 16 CPU-only lanes; the Embedded 8645HS has PCIe Gen 4 with 20 CPU-only lanes. TDP is 55 for the AI Max+ PRO 495 and 45 for the Embedded 8645HS. Base clocks are 3.10 and 4.30, respectively, while boost clocks are 5.20 and 5.00. The AI Max+ PRO 495 has a release date of 2026-05-19, and the Embedded 8645HS has a release date of 2024-04-01. The AI Max+ PRO 495 part number is 100-000002124; the Embedded 8645HS part number is not recorded.

The Verdict

The recorded specifications make the Ryzen AI Max+ PRO 495 the data-driven choice for workloads that use many cores, large caches, and high memory bandwidth. It has 16 cores and 32 threads, 64 MB of L3 cache, and 273.1 GB/s of memory bandwidth. The Ryzen Embedded 8645HS is the data-driven choice for systems where base clock, TDP, and PCIe lane count carry more weight. It has a base clock of 4.30, a TDP of 45, and 20 CPU-only PCIe Gen 4 lanes. The AI Max+ PRO 495 has a higher boost clock, 5.20 versus 5.00, and a different integrated GPU in the Radeon 8065S, while the Embedded 8645HS has the Radeon 760M. Neither processor has recorded benchmark scores, so this verdict relies on the specification data in the database.

Where Each One Wins

The database records no benchmark wins for either side, so the use-case split follows the specification deltas. The Ryzen AI Max+ PRO 495 wins where core count, cache capacity, memory bandwidth, and integrated graphics matter. Its 16 cores and 32 threads give it the advantage in heavily threaded workloads. Its 64 MB L3 cache and 273.1 GB/s memory bandwidth support data-heavy tasks. Its integrated GPU is the Radeon 8065S, while the Embedded 8645HS uses the Radeon 760M. The AI Max+ PRO 495 also has a higher boost clock, 5.20 versus 5.00, so it wins on peak frequency.

The Ryzen Embedded 8645HS wins where base clock, power, and PCIe expansion matter. Its 4.30 base clock is higher than the 3.10 base clock of the AI Max+ PRO 495. Its TDP of 45 is lower than 55. Its 20 CPU-only PCIe Gen 4 lanes exceed the 16 CPU-only PCIe Gen 4 lanes of the AI Max+ PRO 495. The Embedded 8645HS also has an earlier release date, 2024-04-01 versus 2026-05-19, meaning it appears in the database ahead of the AI Max+ PRO 495. Both processors are locked, so the recorded clocks are the fixed operating limits.
