AMD Ryzen AI Embedded P132i vs AMD Ryzen Embedded 8640U Comparison

Head-to-Head Benchmarks

The recorded data for these two processors contains no head-to-head benchmark results, no individual benchmark scores, and no wins for either part. Both CPUs hold a 50th percentile position against all CPUs in the database, and both carry an average benchmark score of 0 from the available measurements. Consequently, there are no exact numerical comparisons to cite for multi-threaded throughput, single-thread performance, or application-specific workloads. The absence of benchmark data means the database cannot currently rank either part above the other in any measured workload category.

The two processors nevertheless differ in their clock strategy. The AMD Ryzen Embedded 8640U starts at a base clock of 3.50 and reaches a boost clock of 4.90. The AMD Ryzen AI Embedded P132i starts at a base clock of 2.00 and reaches a boost clock of 4.50. The 8640U therefore holds a 1.50 advantage at base clock and a 0.40 advantage at boost clock. While clock rates alone do not determine application performance, the 8640U's position suggests it is configured to sustain a higher operating frequency under load, while the P132i's lower base clock points to a more conservative power envelope at idle or lightly threaded states.

Both processors share a 6-core, 12-thread configuration, so thread-level parallelism is identical between them. The data shows no measured performance deltas, no percentile differences, and no nearest rival scores to place these two parts in a comparative performance hierarchy. The database records both as Active production parts, but the lack of benchmark results prevents any verdict on which one delivers higher throughput in either synthetic or real-world tests.

The Verdict

The data does not support a performance verdict. With no benchmark scores, no head-to-head results, and no rival comparisons recorded, neither processor can be declared faster in any measured category. Both are listed with the same 50th percentile versus all CPUs, which is a neutral placement rather than a meaningful equivalence, because it is derived from an average benchmark score of 0 for both parts. The database indicates these two CPUs occupy the same percentile rank, but that rank is not backed by any positive measurement data.

What the data does support is a specification-level distinction. The Ryzen Embedded 8640U carries a 4 nm TSMC process node, a Zen 4 architecture, a "Hawk Point" codename, and a transistor count of 25,000 million on a 178 mm² die. The Ryzen AI Embedded P132i uses a 4 nm TSMC process node, a "Gorgon Point" codename, and a generation listed as "Ryzen AI Embedded (Zen 5 / Zen 5c)." The P132i has no recorded transistor count or die size in the database. The 8640U also offers more PCIe lanes from the CPU: 20 Gen 4 lanes versus 14 Gen 4 lanes for the P132i. The 8640U includes 16 MB of shared L3 cache, while the P132i lists 4 MB of L3 cache. These are architectural and interface differences, not measured performance differences, but they are the primary recorded differentiators.

The verdict from the recorded data is straightforward: the Ryzen Embedded 8640U is the better documented part with a higher clock configuration, a larger L3 cache, more PCIe lanes, and published transistor and die-size figures. The Ryzen AI Embedded P132i is the newer release, dated 2026-03-08 in the database, versus 2024-04-01 for the 8640U, and it uses a newer Zen 5 / Zen 5c generation label. Without benchmark data, the 8640U's higher clocks and larger cache do not automatically translate into a performance win, but they do represent a more aggressive specification sheet.

Where Each One Wins

The AMD Ryzen Embedded 8640U wins on the recorded specification fields. Its base clock of 3.50 is 1.50 higher than the P132i's 2.00. Its boost clock of 4.90 is 0.40 higher than the P132i's 4.50. It provides 20 Gen 4 PCIe lanes from the CPU, compared to 14 for the P132i, which means more direct high-speed I/O capacity for embedded peripherals such as storage controllers, network interfaces, or expansion slots. Its L3 cache is 16 MB shared, while the P132i lists 4 MB, a fourfold difference in the last-level cache partition. The 8640U also has a documented transistor count of 25,000 million and a die size of 178 mm², both absent from the P132i's record. The 8640U supports DDR5 memory, while the P132i supports DDR5 and LPDDR5X, so the P132i holds a memory-type advantage in the other direction.

The AMD Ryzen AI Embedded P132i wins on generation and memory flexibility. Its generation is listed as "Ryzen AI Embedded (Zen 5 / Zen 5c)," which is a newer architecture generation than the 8640U's Zen 4. Its codename is "Gorgon Point," versus "Hawk Point" for the 8640U. The P132i supports LPDDR5X in addition to DDR5, which the 8640U does not list. Its release date of 2026-03-08 is later than the 8640U's 2024-04-01, so the P132i is the more recent product introduction. Both parts use the same AMD Socket FP8, the same 28 TDP, the same dual-channel memory bus, the same 89.6 GB/s memory bandwidth, and the same ECC memory support.

The integrated graphics differ as well. The P132i uses a Radeon 840M, while the 8640U uses a Radeon 760M. The database does not record any graphics benchmark scores for either, so the relative graphics performance cannot be quantified. The P132i's newer architecture and LPDDR5X support are the notable advantages in its column, but they are unquantified in terms of measured performance.

Architecture Differences

The architecture records differ on several core points. The AMD Ryzen Embedded 8640U uses a Zen 4 architecture with the codename "Hawk Point" and is part of the 8000 series. Its generation is listed as "Ryzen Embedded (Zen 4 (Hawk Point))." The AMD Ryzen AI Embedded P132i uses a generation listed as "Ryzen AI Embedded (Zen 5 / Zen 5c)" with the codename "Gorgon Point." This indicates a newer processor generation for the P132i, but the database does not list a separate architecture field for it. Both parts are fabricated by TSMC on a 4 nm process node.

The cache hierarchy differs in structure. The 8640U has 64 KB of L1 cache per core, 1 MB of L2 cache per core, and 16 MB of shared L3 cache. The P132i has 80 KB of L1 cache per core, 1 MB of L2 cache per core, and 4 MB of L3 cache. The P132i therefore has a larger per-core L1 allocation, while the 8640U has a substantially larger L3 pool. The 8640U also records a transistor count of 25,000 million and a die size of 178 mm², while the P132i has no transistor or die-size figures in the database.

The integrated graphics differ: the 8640U carries a Radeon 760M, and the P132i carries a Radeon 840M. The database records no graphics performance data for either.
