AMD Ryzen Embedded 8645HS vs Intel Core 5 221E Comparison

AMD Ryzen Embedded 8645HS and Intel Core 5 221E target different segments of the embedded and desktop markets, and the recorded data shows a clear split in their strengths. The AMD part is a 6-core, 12-thread mobile processor built on TSMC’s 4 nm process, while the Intel part is a 14-core, 20-thread desktop processor on Intel’s 10 nm process. Benchmark results for the Intel Core 5 221E place it in the 87th percentile of all CPUs, with an average benchmark score of 40144, whereas the AMD Ryzen Embedded 8645HS has no recorded benchmark scores in the database, leaving its percentile at 50 and its average score at 0. This absence of direct measurements for the AMD part shapes the analysis: the Intel processor’s wins are documented, while the AMD processor’s capabilities must be inferred from its architectural specifications.

Where Each One Wins

The Intel Core 5 221E wins on raw multi-threaded throughput. Its 14 cores and 20 threads give it a substantial core-count advantage over the AMD Ryzen Embedded 8645HS, which has 6 cores and 12 threads. The database records the Intel part’s Cinebench R23 multi-core score at 25933, a figure that reflects its ability to handle heavily parallel workloads such as rendering, compilation, and scientific simulation. The AMD part, with fewer cores and no recorded benchmarks, cannot be placed ahead in any measured multi-threaded test.

The AMD Ryzen Embedded 8645HS wins on clock speed per core. Its base clock of 4.30 GHz and boost clock of 5.00 GHz exceed the Intel Core 5 221E’s base clock of 2.70 GHz and boost clock of 5.20 GHz. While the Intel part has a higher boost ceiling, the AMD part’s much higher base clock suggests stronger sustained single-thread performance in power-constrained scenarios, particularly relevant for a 45 W TDP mobile processor versus the Intel part’s 65 W TDP. The AMD processor also uses a more advanced process node, 4 nm from TSMC, compared to Intel’s 10 nm process, which typically indicates better power efficiency per clock.

The Intel Core 5 221E wins on memory flexibility. It supports both DDR4 and DDR5 memory, while the AMD Ryzen Embedded 8645HS supports only DDR5. Both processors have dual-channel memory buses and identical recorded memory bandwidth of 89.6 GB/s, but the Intel part’s ability to use older, more widely available DDR4 modules gives it an advantage in system integration where DDR4 is already deployed.

The AMD Ryzen Embedded 8645HS wins on PCIe generation. It uses PCIe Gen 4 with 20 lanes, while the Intel Core 5 221E uses PCIe Gen 5 with 16 lanes. Although the Intel part has a newer PCIe standard, the AMD part offers more lanes, which can be beneficial for embedded applications requiring multiple simultaneous high-bandwidth devices.

Architecture Differences

The two processors come from different architectural families. The AMD Ryzen Embedded 8645HS uses Zen 4 architecture under the codename Hawk Point, part of Ryzen Embedded’s 8000 series. The Intel Core 5 221E uses the Bartlett Lake codename, with its generation listed as Core 5 (Bartlett Lake). The AMD part is fabricated by TSMC on a 4 nm process with 25,000 million transistors on a 178 mm² die. The Intel part is fabricated by Intel on a 10 nm process with a 257 mm² die size; the database does not record its transistor count.

Cache organization differs significantly. The AMD Ryzen Embedded 8645HS has 64 KB of L1 cache per core, 1 MB of L2 cache per core, and 16 MB of shared L3 cache. The Intel Core 5 221E has 80 KB of L1 cache per core, 2 MB of L2 cache per core, and 24 MB of shared L3 cache. The Intel part has a larger total cache footprint per core and a larger shared L3 pool, which can help in workloads with larger working sets.

Integrated graphics differ as well. The AMD Ryzen Embedded 8645HS uses Radeon 760M graphics, while the Intel Core 5 221E uses UHD Graphics 730. The database records no benchmark scores for either integrated GPU, so direct comparison is not possible from the available data.

The AMD part is classified as a mobile processor with an AMD Socket FP8 package, while the Intel part is classified as a desktop processor with an Intel Socket 1700 package. The Intel part has a recorded part number of SRQDVQ659, whereas the AMD part’s part number is listed as unknown. Both processors support ECC memory and have locked multipliers, meaning neither offers overclocking through unlocked clock multipliers.

Head-to-Head Benchmarks

Direct head-to-head benchmark data between the two processors is not present in the database. The head-to-head benchmark array is empty, and the wins count for both processors is zero. The only recorded benchmarks belong to the Intel Core 5 221E, so the analysis must rely on those scores alongside the AMD part’s specifications.

The Intel Core 5 221E’s Cinebench R23 multi-core score is 25933, and its single-core score is 3661. In Cinebench R20, it scores 10891 multi-core and 1537 single-core. In Cinebench R15, it scores 2613 multi-core and 368 single-core. These results show a processor with strong scaling across generations of the Cinebench test, with multi-core scores roughly seven times the single-core scores, which aligns with its 14-core, 20-thread configuration.

PassMark results for the Intel Core 5 221E show its strongest areas. The multithread score is 30510, the single-thread score is 4147, integer math scores 117813, floating-point math scores 79028, data compression scores 324285, and data encryption scores 19205. Extended instructions score 18216, find prime numbers scores 173, random string sorting scores 37686, and physics scores 2230. These numbers indicate that the Intel part excels at integer and floating-point math, while its prime number search score is comparatively low, suggesting a relative weakness in that specific workload.

The nearest rivals for the Intel Core 5 221E provide context for its average benchmark score of 40144. The AMD Ryzen 7 7700 scores 40081, a delta of 0.2 percent, meaning the Intel part is effectively tied with it. The AMD Ryzen AI 9 365 scores 40048, also a delta of 0.2 percent. The AMD Ryzen 9 270 scores 40246, a delta of -0.3 percent, meaning that rival is slightly ahead. The Intel Core i9-13905H scores 40313, a delta of -0.4 percent, also slightly ahead. These deltas are all within a fraction of a percent, indicating that the Intel Core 5 221E sits in a tight performance cluster with these four rivals, none of which is decisively faster or slower in average benchmark score.
