AMD Ryzen Embedded 8640U vs Intel Core 5 221TE Comparison

The database record for this comparison is asymmetric. The AMD Ryzen Embedded 8640U and Intel Core 5 221TE are both active processors, but only the Intel part carries benchmark scores: an average benchmark score of 17860 and a 71st percentile rank. The AMD part has no recorded benchmark entries, an average benchmark score of 0, and a 50th percentile rank. The specification sheets therefore carry most of the comparison weight, with Intel's measured results providing the only workload data.

Where Each One Wins

Based on the recorded benchmark wins, the Intel Core 5 221TE is the only processor in this pair with wins to assign. It has entries across Cinebench R15, R20, R23 and the Passmark suite. The AMD Ryzen Embedded 8640U has no benchmark entries, so no benchmark wins can be credited to it.

In terms of use cases, the Intel part's scores cover threaded rendering, single-thread performance, and Passmark math and integer workloads. The AMD part's use-case profile comes from its specifications: a 28 W mobile embedded chip with 6 Zen 4 cores, 12 threads, Radeon 760M integrated graphics, and DDR5 support. The data does not show the AMD part winning any recorded benchmark, while the Intel part holds all recorded benchmark results.

Architecture Differences

AMD's processor is built around Zen 4 with the Hawk Point codename, uses a 4 nm TSMC process, and contains 25,000 million transistors on a 178 mm² die. Intel's processor uses the Bartlett Lake codename, a 10 nm Intel process, and a 215 mm² die; its architecture is not recorded in the database.

The AMD part has 6 cores and 12 threads with a 3.50 GHz base clock and a 4.90 GHz boost clock. The Intel part has 10 cores and 16 threads with a 1.80 GHz base clock and a 5.00 GHz boost clock. Cache layouts differ at every level: AMD uses 64 KB of L1 per core, 1 MB of L2 per core, and 16 MB of shared L3; Intel uses 80 KB of L1 per core, 1.25 MB of L2 per core, and 24 MB of shared L3.

Both support ECC memory. AMD supports DDR5 on a dual-channel bus with 89.6 GB/s of bandwidth; Intel supports DDR4 and DDR5 on a dual-channel bus with 76.8 GB/s. AMD exposes PCIe Gen 4 with 20 CPU lanes; Intel exposes PCIe Gen 5 with 16 CPU lanes. AMD integrates Radeon 760M graphics; Intel integrates UHD Graphics 730. AMD uses Socket FP8 and is classified as mobile; Intel uses Socket 1700 and is classified as desktop.

Head-to-Head Benchmarks

No direct head-to-head benchmark records exist for this pair. The AMD part has no benchmark entries, so there is no Intel-versus-AMD score to walk through. The Intel part's recorded results are the complete measured picture.

In Cinebench, the Intel part scores 11305 in R23 multi-core and 1596 in R23 single-core, 4748 in R20 multi-core and 670 in R20 single-core, and 1139 in R15 multi-core and 160 in R15 single-core. In Passmark, the largest recorded scores are data compression 156682, integer math 42303, floating point math 31661, multithread 13301, and random string sorting 16929. The remaining Passmark entries are extended instructions 9655, data encryption 8963, physics 977, single thread 1734, and find prime numbers 59.

The Intel part's closest competitors in the database are AMD Ryzen 5 3600XT with an average score of 17891 and a relative difference of -0.2, Intel Core 5 120U with 17898 and -0.2, Intel Core 7 350 with 17779 and 0.5, and AMD Ryzen 5 1600 with 17994 and -0.7. These relative differences are all close to zero, indicating that the Intel part sits in a tight performance cluster despite having no direct comparison data against the AMD embedded part.

The Verdict

The data separates these two processors by segment and by benchmark coverage. The Intel Core 5 221TE is the only part with measured workload scores, an average benchmark score of 17860, and a 71st percentile rank. The AMD Ryzen Embedded 8640U has no measured scores, an average benchmark score of 0, and a 50th percentile rank.

For applications that rely on Cinebench or Passmark results, the Intel part is the only processor in this comparison with recorded evidence. For an embedded mobile platform that requires a 28 W processor with 6 Zen 4 cores, 12 threads, Radeon 760M graphics, and DDR5 support, the AMD part is the only match in this pair. The Intel part's 45 W desktop design, 10 cores, 16 threads, UHD Graphics 730, and dual DDR4/DDR5 support address a different platform requirement. Strictly from the database, the Intel part claims all recorded benchmark wins, while the AMD part claims the embedded mobile specification profile.
