AMD Ryzen 5 PRO 8640HS vs AMD Ryzen Embedded 9950X3D Comparison

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark results between the AMD Ryzen 5 PRO 8640HS and the AMD Ryzen Embedded 9950X3D. The headToHeadBenchmarks field is empty, and the win counters for both processors stand at zero. This absence of paired measurements means the comparison must rely on the separately recorded benchmark scores for the Ryzen 5 PRO 8640HS and the architectural specifications of the Ryzen Embedded 9950X3D.

The Ryzen 5 PRO 8640HS has a complete benchmark profile. Its Cinebench R23 multi-core score is 18,104, while its single-core score is 2,555. In Cinebench R20, the multi-core result is 7,603 and the single-core result is 1,073. The older Cinebench R15 test shows 1,824 multi-core and 257 single-core. PassMark results include a multi-thread score of 21,465, a single-thread score of 3,561, integer math at 69,839, floating point math at 43,019, extended instructions at 18,507, data compression at 246,446, data encryption at 14,962, prime number finding at 71, physics at 1,043, and random string sorting at 30,235.

The Ryzen Embedded 9950X3D has no recorded benchmark scores in the database. Its average benchmark score is 0, and its percentile versus all CPUs is 50. The Ryzen 5 PRO 8640HS, by contrast, holds an 80th percentile ranking among all CPUs and an average benchmark score of 28,478. Without any measured scores for the embedded chip, quantifying a head-to-head performance gap is impossible from the recorded data. The Ryzen 5 PRO 8640HS sits within 0.3% of several close rivals in average score: it trails the Intel Xeon E-2436 by 0.2%, trails the AMD Ryzen 7 PRO 6850HS by 0.2%, trails the Intel Core 5 220H by 0.3%, and leads the AMD Ryzen 7 PRO 6850U by 0.3%. These deltas place the 8640HS in a tightly contested performance band.

Architecture Differences

The two processors diverge substantially in core configuration and cache hierarchy. The Ryzen 5 PRO 8640HS uses 6 cores and 12 threads, built on Zen 4 architecture under the Hawk Point codename. The Ryzen Embedded 9950X3D uses 16 cores and 32 threads, built on Zen 5 architecture under the Granite Ridge codename. Both parts are fabricated on a 4 nm process at TSMC, but the transistor counts differ markedly: the 8640HS integrates 25,000 million transistors on a 178 mm² die, while the 9950X3D uses 16,630 million transistors across a dual-chiplet layout of 2x 70.6 mm².

Clock speeds favor the embedded part substantially. The Ryzen 5 PRO 8640HS has a base clock of 3.50 GHz and a boost clock of 4.90 GHz. The Ryzen Embedded 9950X3D starts at 4.30 GHz base and reaches 5.70 GHz boost. Power envelopes reflect the different market segments: the 8640HS is rated at 28 W TDP, while the 9950X3D draws 170 W TDP. This 142 W gap in thermal design power corresponds to the desktop versus mobile positioning of the two chips.

Cache configurations show a major difference in L3 capacity. The Ryzen 5 PRO 8640HS provides 64 KB of L1 per core, 1 MB of L2 per core, and 16 MB of shared L3. The Ryzen Embedded 9950X3D provides 80 KB of L1 per core, 1 MB of L2 per core, and 128 MB of L3. The embedded processor thus carries 8 times the L3 cache of the mobile chip, a cache advantage that often benefits workloads with large working sets. Neither part is listed with 3D V-Cache in the database, despite the X3D suffix on the embedded model; the vCache3d field is null for both.

Memory support is identical in type and bus width: both use DDR5 with a dual-channel memory bus and a recorded memory bandwidth of 89.6 GB/s. Both also support ECC memory. PCIe capabilities differ by generation and lane count. The Ryzen 5 PRO 8640HS uses PCIe Gen 4 with 20 lanes from the CPU. The Ryzen Embedded 9950X3D uses PCIe Gen 5 with 24 lanes from the CPU. This gives the desktop part both a higher lane count and a newer PCIe generation.

Integrated graphics differ in naming. The 8640HS carries a Radeon 760M, while the 9950X3D carries a generic Radeon Graphics. The database does not provide detailed specifications for either GPU, so no performance comparison can be drawn. The market segment designation also differs: the 8640HS is classified as Mobile, and the 9950X3D is classified as Desktop. Sockets are incompatible, with the 8640HS using AMD Socket FP7 and the 9950X3D using AMD Socket AM5.

The multiplier is locked on the Ryzen 5 PRO 8640HS and unlocked on the Ryzen Embedded 9950X3D. Release dates place the 8640HS on 2024-04-15 and the 9950X3D on 2025-10-06. Both parts are listed as Active in production status.

The Verdict

The recorded data supports a clear split by workload type and platform. The Ryzen 5 PRO 8640HS is the only one of the two with empirical benchmark results. Its 80th percentile ranking among all CPUs and average score of 28,478 place it in a competitive band against the Intel Xeon E-2436, AMD Ryzen 7 PRO 6850HS, Intel Core 5 220H, and AMD Ryzen 7 PRO 6850U, all within 0.3% of its average score. For users constrained to a 28 W TDP mobile platform, the 8640HS delivers measured multi-thread performance of 18,104 in Cinebench R23 and a single-thread score of 2,555, with a boost clock of 4.90 GHz.

The Ryzen Embedded 9950X3D offers no measured scores in the database, so its performance cannot be quantified from the recorded data. What the specifications do show is a substantially higher core count, 16 versus 6, and a larger L3 cache, 128 MB versus 16 MB. Its 5.70 GHz boost clock and 4.30 GHz base clock exceed the 8640HS on both counts. The 170 W TDP indicates a much higher power envelope than the 28 W mobile part. The 9950X3D also provides PCIe Gen 5 with 24 lanes, versus PCIe Gen 4 with 20 lanes on the 8640HS, and supports an unlocked multiplier.

Selecting between these parts depends on whether the workload requires the measured efficiency and mobility of the 8640HS or the raw core and cache resources of the 9950X3D. The 8640HS has the advantage of a validated benchmark profile and a much lower power draw. The 9950X3D has the advantage of double the cores, quadruple the threads, 8 times the L3 cache, higher clocks, and a newer PCIe generation, but no benchmark confirmation in this database. The data cannot certify the embedded part's performance, only its architectural headroom.
