AMD Ryzen Embedded 8640U vs Intel Core 7 251TE Comparison

Head-to-Head Benchmarks

The recorded database contains no direct head-to-head benchmark scores for the AMD Ryzen Embedded 8640U versus the Intel Core 7 251TE. The head-to-head benchmark array is empty, and the win counters show zero wins for each processor. This absence of paired testing data means any comparison must rely on the single recorded benchmark suite for the Intel part and the architectural specifications of the AMD part.

What the data does show is a substantial benchmark profile for the Intel Core 7 251TE. In Cinebench R23, the Intel chip records a multicore score of 25,518 and a single-core score of 3,602. The R20 results show 10,717 multicore and 1,512 single-core, while R15 yields 2,572 multicore and 362 single-core. These numbers place the Intel processor at the 88th percentile among all CPUs in the database, with an average benchmark score of 41,650.

PassMark results for the Intel part are extensive. Integer math scores 125,739, floating-point math reaches 85,607, and extended instructions hit 16,974. Data compression scores 334,399, while data encryption records 22,176. Multithread performance is 30,022, physics scores 1,938, and random string sorting reaches 39,643. Single-thread performance is 3,568. Find prime numbers scores 140.

The nearest rivals for the Intel Core 7 251TE, based on average benchmark scores, provide context. The Intel Core Ultra 7 265H scores 41,621, a negligible 0.1% difference. The Intel Core i7-14650HX scores 41,576, also 0.2% behind. The Intel Core i7-12850HX scores 41,779, which is 0.3% ahead of the Core 7 251TE. The Intel Core i7-14700T scores 41,914, sitting 0.6% higher. These deltas are all within a single percentage point, indicating that the Core 7 251TE performs essentially on par with a cluster of high-end Intel mobile and desktop parts.

Without head-to-head benchmarks, the AMD Ryzen Embedded 8640U cannot be assigned a comparative score. The database lists its average benchmark score as zero and its percentile as 50, which reflects the absence of recorded benchmark runs rather than actual performance. The AMD chip's specifications, however, allow for qualitative analysis.

The Verdict

The data supports a clear choice for users who need maximum multi-threaded throughput: the Intel Core 7 251TE. Its 24 cores and 32 threads, combined with a 5.40 GHz boost clock, produce benchmark scores that place it in the 88th percentile of all CPUs. The Cinebench R23 multicore score of 25,518 and PassMark multithread score of 30,022 indicate strong parallel processing capability.

The AMD Ryzen Embedded 8640U, with 6 cores and 12 threads, offers a different profile. Its 4.90 GHz boost clock and Zen 4 architecture suggest capable single-thread performance, but the database contains no recorded scores to confirm this. The AMD chip's 28 W TDP contrasts sharply with the Intel chip's 45 W TDP, which implies lower power draw for the AMD part, though the database does not provide efficiency benchmarks.

For users prioritizing raw compute results, the recorded data overwhelmingly favors the Intel Core 7 251TE. For users prioritizing a compact, lower-power embedded solution, the AMD part may hold appeal, but the lack of benchmark data means this cannot be quantified. The nearest rivals to the Intel chip all score within 0.6% of it, confirming that the Core 7 251TE sits in a well-established performance tier.

Where Each One Wins

The Intel Core 7 251TE wins on every measurable benchmark in the database, simply because it is the only processor with recorded scores. Its 24-core configuration with 32 threads gives it a structural advantage in multi-threaded workloads. The Cinebench R20 multicore score of 10,717 and PassMark integer math score of 125,739 demonstrate strong sustained throughput. The data compression score of 334,399 is particularly notable, suggesting excellent performance in compression and archival tasks.

The AMD Ryzen Embedded 8640U wins on thermal design power, with a 28 W TDP compared to the Intel chip's 45 W. This 17-watt difference indicates the AMD part generates less heat and requires less cooling, which is a meaningful advantage in embedded applications where space and thermal constraints are tight. The AMD chip also uses a 4 nm process from TSMC, while the Intel chip uses a 10 nm process from Intel, which likely contributes to the power efficiency difference.

The AMD part's Radeon 760M integrated graphics may outperform the Intel UHD Graphics 770 in certain graphics workloads, though the database provides no graphics benchmarks to confirm this. The AMD chip's 6 cores and 12 threads suggest it is better suited for light, latency-sensitive tasks, while the Intel chip's 24 cores and 32 threads excel in heavily parallel workloads like rendering, encoding, and scientific computation.
