AMD Ryzen 5 7500X3D vs AMD Ryzen Embedded 8640U Comparison

Head-to-Head Benchmarks

The benchmark database contains a complete set of PassMark measurements for the AMD Ryzen 5 7500X3D, while the AMD Ryzen Embedded 8640U has no recorded scores in the database. This creates an asymmetric comparison: the 7500X3D's performance profile is fully characterized, whereas the 8640U's results are absent, making direct head-to-head deltas impossible to compute. The 7500X3D's average benchmark score of 44573 places it at the 89th percentile of all CPUs, while the 8640U sits at the 50th percentile with an average score of zero, reflecting the missing data rather than actual performance.

The 7500X3D's strongest recorded result is in PassMark data compression, where it scores 271649. This figure stands far above its other workload scores, indicating exceptional throughput in compression tasks. Data encryption follows at 15797, a comparatively modest number, while extended instructions reach 20455. The floating point math score of 43594 and integer math score of 70774 show a balanced arithmetic capability. Random string sorting delivers 32999, and the multithread score of 25047 confirms strong parallel execution across its 6 cores and 12 threads. Single-thread performance is recorded at 3494, with physics at 2779 and find prime numbers at 221.

Since the 8640U has no benchmark entries, the rivalry structure for the 7500X3D provides context from other processors. The nearest rival is the Intel Core Ultra X9 388H with an average score of 44466, which is 0.2% behind the 7500X3D. The Intel Core i9-13950HX scores 44342, trailing by 0.5%. The AMD Ryzen AI Max 385 records 44309, a 0.6% deficit. The Intel Core i5-14600 leads slightly with 44889, outperforming the 7500X3D by 0.7%. These margins are all within a single percentage point, indicating that the 7500X3D sits in a tightly contested performance band where no clear winner emerges among these rivals.

The absence of 8640U benchmarks means the database cannot confirm any wins for either processor in a direct comparison. The 7500X3D's recorded scores stand alone, while the 8640U's performance remains unverified. This makes the head-to-head section necessarily one-sided: the 7500X3D has a full profile, and the 8640U has none.

Where Each One Wins

The 7500X3D wins in every measurable category because it is the only processor in this comparison with recorded data. Its 6-core, 12-thread configuration delivers a multithread score of 25047, which aligns with its 89th percentile ranking. The data compression score of 271649 is the standout result, suggesting workloads involving archiving, file transfer, or database operations would benefit most. Integer math at 70774 and floating point math at 43594 indicate strong general computation, while the single-thread score of 3494 shows capable per-core performance for lightly threaded tasks.

The 8640U cannot claim wins in any benchmark category due to missing data. Its specifications, however, provide qualitative expectations: a 28 W TDP versus the 7500X3D's 65 W TDP suggests the embedded processor is designed for power-constrained environments. The 8640U's boost clock of 4.90 GHz exceeds the 7500X3D's 4.50 GHz, which could favor bursty single-thread workloads if the database had scores to confirm it. The 8640U's 4 nm process node versus the 7500X3D's 5 nm node implies better transistor density, and its 25,000 million transistors on a 178 mm² die contrast with the 7500X3D's 11,270 million transistors on a 71 mm² die.

The 8640U's integrated Radeon 760M graphics are more explicitly named than the 7500X3D's generic Radeon Graphics, suggesting a stronger integrated GPU presence for embedded or mobile use cases. The 8640U also has higher memory bandwidth at 89.6 GB/s versus 83.2 GB/s, which could improve memory-intensive operations. Neither processor has a confirmed win without the 8640U's benchmarks, so the practical split is that the 7500X3D wins all recorded tests, while the 8640U's advantages remain speculative based on its listed specifications.

Memory bandwidth is higher on the 8640U at 89.6 GB/s versus 83.2 GB/s for the 7500X3D. PCIe support differs, with the 7500X3D offering Gen 5 with 24 lanes (CPU only) and the 8640U offering Gen 4 with 20 lanes (CPU only). The integrated graphics are listed as Radeon Graphics for the 7500X3D and Radeon 760M for the 8640U. Market segments differ: the 7500X3D is Desktop, and the 8640U is Mobile.

The release dates are different: the 7500X3D launched on 2025-11-11, while the 8640U launched on 2024-04-01. The 7500X3D has a launch MSRP of $269, while the 8640U has no recorded launch MSRP. The part number for the 7500X3D is 100-000001904, while the 8640U's part number is unknown. Both processors have 6 cores and 12 threads, and both have a locked multiplier.

Architecture Differences

The architecture details reveal substantial differences. The 7500X3D is part of the 7000 series with the codename Raphael, while the 8640U is from the 8000 series with the codename Hawk Point. The 7500X3D's generation is listed as Ryzen 5 (Zen 4 (Raphael)), and the 8640U's generation is Ryzen Embedded (Zen 4 (Hawk Point)). Both use the Zen 4 architecture, but the 7500X3D's process node is 5 nm, while the 8640U's is 4 nm, both from TSMC.

Transistor counts differ significantly: the 7500X3D has 11,270 million transistors on a 71 mm² die, while the 8640U has 25,000 million transistors on a 178 mm² die. Cache configurations also diverge: the 7500X3D has 96 MB of shared L3 cache, whereas the 8640U has 16 MB of shared L3 cache. Both share 64 KB of L1 cache per core and 1 MB of L2 cache per core.

The 7500X3D's large L3 cache is characteristic of the 3D V-Cache design, though the database does not explicitly list a vCache3d field value for either processor. The 8640U's smaller cache footprint, combined with its 4 nm node and higher transistor count, suggests a denser but differently optimized design. The 7500X3D uses Gen 5 PCIe with 24 lanes, while the 8640U uses Gen 4 with 20 lanes. Both support DDR5 dual-channel memory and ECC, but the 8640U's higher memory bandwidth of 89.6 GB/s versus 83.2 GB/s reflects its embedded-oriented design. The 7500X3D's production status is Active, as is the 8640U's, and both have locked multipliers.
