AMD Ryzen 3 3100U vs AMD Ryzen Embedded 8640U Comparison

Head-to-Head Benchmarks

The benchmark database does not include direct head-to-head measurements between the AMD Ryzen 3 3100U and the AMD Ryzen Embedded 8640U. The head-to-head benchmark array is empty, and the recorded win counts sit at zero for both processors. Consequently, any comparison must rely on the individual PassMark results recorded for the Ryzen 3 3100U and the architectural specifications of the Ryzen Embedded 8640U.

The Ryzen 3 3100U has a recorded PassMark single-thread score of 1592 and a PassMark multi-thread score of 3348. Its average benchmark score across all tests is 6247, placing it at the 62nd percentile among all CPUs in the database. In integer math, it scores 8873, and in floating-point math, it scores 5854. Data compression yields a score of 38455, while data encryption sits at 1972. Extended instruction workloads record 2116, and the find-prime-numbers test produces a score of 18. Random string sorting scores 4666, and physics processing records 232.

Because the Ryzen Embedded 8640U has no recorded benchmark scores in the database, its average benchmark score is listed as 0, and its percentile rank is 50. The data does not permit a direct numerical comparison of performance deltas between these two parts. The nearest rivals for the Ryzen 3 3100U include the AMD Ryzen Threadripper 1950X with an average score of 6231 and a delta of 0.3%, the AMD EPYC 7272 with an average score of 6186 and a delta of 1%, the Intel Core i9-10920X with an average score of 6347 and a delta of -1.6%, and the Intel Core i9-7940X with an average score of 6147 and a delta of 1.6%. These figures indicate the Ryzen 3 3100U sits within a narrow band of desktop and server parts from previous generations, slightly ahead of the EPYC 7272 and the i9-7940X, and slightly behind the i9-10920X.

The absence of benchmark data for the Ryzen Embedded 8640U means the database offers no measured evidence of its performance in the same workloads. The analysis must instead rely on the architectural differences between the two chips to infer relative capability.

Cache configuration includes 96 KB of L1 per core, 512 KB of L2 per core, and 4 MB of shared L3 cache. Memory support is DDR4 in a dual-channel configuration with a bandwidth of 38.4 GB/s. ECC memory is not supported. The PCIe interface is Gen 3. Integrated graphics are provided by Radeon Vega 8. The release date is recorded as 2026-05-31.

The AMD Ryzen Embedded 8640U belongs to the 8000 series and uses the Hawk Point codename, built on the Zen 4 architecture. It is fabricated on a 4 nm process at TSMC, with 25,000 million transistors on a 178 mm² die. The chip contains 6 cores and 12 threads, with a base clock of 3.50 GHz and a boost clock of 4.90 GHz. Its thermal design power is 28 watts, and it uses the AMD Socket FP8. Cache configuration includes 64 KB of L1 per core, 1 MB of L2 per core, and 16 MB of shared L3 cache. Memory support is DDR5 in a dual-channel configuration with a bandwidth of 89.6 GB/s. ECC memory is supported. The PCIe interface is Gen 4 with 20 lanes available to the CPU. Integrated graphics are provided by Radeon 760M. The release date is recorded as 2024-04-01.

The node difference is substantial: 12 nm versus 4 nm, which reflects a generational leap in transistor density. The transistor count grows from 4,940 million to 25,000 million, while the die shrinks from 210 mm² to 178 mm². The core count triples from 2 to 6, and thread count jumps from 2 to 12. Clock speeds also rise considerably: base clock moves from 1.90 GHz to 3.50 GHz, and boost clock from 3.20 GHz to 4.90 GHz. The L3 cache quadruples from 4 MB to 16 MB, and the L2 cache per core doubles from 512 KB to 1 MB. Memory bandwidth more than doubles from 38.4 GB/s to 89.6 GB/s, and the memory type advances from DDR4 to DDR5. PCIe generation moves from Gen 3 to Gen 4, with the Embedded part offering 20 CPU lanes. ECC support appears only on the Embedded part. The integrated GPU changes from Radeon Vega 8 to Radeon 760M.

The Verdict

The database contains no head-to-head benchmark results between these two processors, and the Ryzen Embedded 8640U has no recorded benchmark scores at all. The only measured performance data belongs to the Ryzen 3 3100U, which achieves an average benchmark score of 6247 and sits at the 62nd percentile. The Ryzen Embedded 8640U sits at the 50th percentile with an average score of 0, but that figure reflects missing data rather than measured performance.

The architectural record tells a clear story. The Ryzen Embedded 8640U is a newer, larger part: 6 cores versus 2, 12 threads versus 2, a 4 nm process versus 12 nm, a 4.90 GHz boost clock versus 3.20 GHz, 16 MB of L3 cache versus 4 MB, and DDR5 memory with 89.6 GB/s bandwidth versus DDR4 with 38.4 GB/s. It also supports ECC memory and uses PCIe Gen 4 with 20 lanes, while the Ryzen 3 3100U uses PCIe Gen 3. The Embedded part carries a higher TDP of 28 watts versus 15 watts, reflecting the additional cores and higher clocks.

A user selecting between these parts should base the decision on the architectural facts. The Ryzen Embedded 8640U offers substantially more compute resources, newer memory technology, higher bandwidth, and ECC support. The Ryzen 3 3100U offers a lower power envelope and an older, smaller design. The absence of benchmark data for the Embedded part means its measured performance cannot be confirmed from the database, but the specifications indicate a significant generational and core-count advantage for the 8640U.

Where Each One Wins

The Ryzen 3 3100U wins in power efficiency on paper. Its 15-watt TDP is lower than the 28-watt TDP of the Ryzen Embedded 8640U, making it the more suitable choice for thermally constrained mobile designs. It also has a smaller transistor count and a larger die, which reflects an older manufacturing process but also a simpler chip. The database shows it has a measured performance record, with an average benchmark score of 6247 and a 62nd percentile standing, so its behavior in those workloads is documented.

The Ryzen Embedded 8640U wins in raw compute resources. It offers three times the cores and six times the threads. Its base and boost clocks are substantially higher, and it carries four times the L3 cache. Memory bandwidth is more than double, and it supports DDR5 with ECC, which matters for embedded and server-style workloads where data integrity is critical. The PCIe Gen 4 interface with 20 CPU lanes provides more modern I/O connectivity. Its smaller 4 nm die with 25,000 million transistors indicates a denser, more advanced design. The Radeon 760M integrated graphics represent a newer GPU generation than the Radeon Vega 8.

The recorded data does not include any benchmark wins for either part, since the head-to-head array is empty. The practical split is therefore clear from specifications: the Ryzen 3 3100U fits lower-power, lighter-duty mobile roles where its measured single-thread score of 1592 and multi-thread score of 3348 are sufficient. The Ryzen Embedded 8640U targets workloads requiring more cores, higher memory bandwidth, ECC support, and modern PCIe connectivity, though its measured performance remains unrecorded in the database.
