AMD Ryzen Embedded 8640U vs Intel Core 9 273PE Comparison

Where Each One Wins

The benchmark data splits cleanly along workload type. The Intel Core 9 273PE dominates every recorded measurement in the database, with the AMD Ryzen Embedded 8640U showing no wins in any of the 17 benchmark entries. The Intel part records scores across Cinebench R15, R20, and R23, plus PassMark tests covering integer math, floating point math, encryption, compression, physics, and single-threaded tasks. The AMD processor has no recorded benchmark scores in the database, which places it at the 50th percentile of all CPUs with an average benchmark score of zero.

The Intel Core 9 273PE sits at the 90th percentile of all CPUs, a substantial gap from the AMD chip's 50th percentile placement. Its average benchmark score of 49,845 reflects strong performance across the full test suite. The nearest rivals bracket this result closely: the AMD Ryzen AI Max+ 388 scores 49,796 (0.1% ahead), the Intel Core i5-14600KF scores 49,394 (0.9% behind), the Intel Core i9-13980HX scores 50,398 (1.1% ahead), and the AMD Ryzen AI 9 HX PRO 370 scores 50,448 (1.2% ahead). The Intel Core 9 273PE effectively trades places with these processors within a narrow 1.2% band.

The AMD Ryzen Embedded 8640U, lacking recorded scores, cannot be positioned against those rivals. Its 6 cores and 12 threads, 28 W TDP, and mobile market segment suggest a design aimed at embedded power envelopes, while the Intel chip's 12 cores, 24 threads, and 65 W TDP target desktop workloads. The data indicates the Intel processor wins in every measured category, making the use-case split straightforward: the Intel part is the performance option, the AMD part is the lower-power embedded option with no benchmark evidence of competitive throughput.

Head-to-Head Benchmarks

The head-to-head benchmark list is empty, so the comparison relies on the Intel Core 9 273PE's recorded scores and the AMD Ryzen Embedded 8640U's absence of any scores. The Intel chip's Cinebench results show the shape of its performance. In Cinebench R23, it scores 31,288 in multi-core and 4,417 in single-core. The multi-core figure is 7.1 times the single-core figure, which aligns with its 12-core, 24-thread configuration scaling across threaded workloads. In Cinebench R20, the scores are 13,140 multi-core and 1,855 single-core, a ratio of 7.1 again, confirming consistent scaling. Cinebench R15 shows 3,153 multi-core and 445 single-core, a ratio of 7.1 as well.

PassMark results add detail. The multithread score is 36,810, while the single-thread score is 3,650, a ratio of 10.1, indicating even stronger thread scaling in that suite. Integer math scores 139,410, floating point math scores 107,884, and extended instructions score 24,630. Data compression scores 405,885, the highest single benchmark figure recorded, while data encryption scores 22,719. Random string sorting scores 45,098. Find prime numbers scores 203 and physics scores 3,120, both lower figures reflecting their specific computational demands.

The AMD Ryzen Embedded 8640U has zero recorded benchmark scores, so no direct deltas exist against the Intel chip. The database shows wins A at 0 and wins B at 0 for the head-to-head field, but the Intel part's individual benchmark entries are all positive, while the AMD part has none. The Intel Core 9 273PE's nearest rival comparisons provide context: it sits 0.1% behind the AMD Ryzen AI Max+ 388, 0.9% ahead of the Intel Core i5-14600KF, 1.1% behind the Intel Core i9-13980HX, and 1.2% behind the AMD Ryzen AI 9 HX PRO 370. Those deltas are small, suggesting the Intel part competes at a specific performance tier, but the AMD Ryzen Embedded 8640U cannot be placed in that tier without data.

Specification Differences

The core counts differ sharply: the AMD Ryzen Embedded 8640U has 6 cores and 12 threads, the Intel Core 9 273PE has 12 cores and 24 threads. Base clocks differ by 1.20 GHz in AMD's favor (3.50 GHz versus 2.30 GHz), while boost clocks differ by 0.80 GHz in Intel's favor (5.70 GHz versus 4.90 GHz). TDPs differ by 37 W: 28 W for AMD, 65 W for Intel.

The process nodes diverge: AMD uses 4 nm at TSMC with 25,000 million transistors on a 178 mm² die; Intel uses 10 nm at its own foundry with no transistor or die size recorded. Cache layouts differ across all levels. AMD has 64 KB L1 per core, 1 MB L2 per core, and 16 MB shared L3. Intel has 80 KB L1 per core, 2 MB L2 per core, and 36 MB shared L3. Memory support differs: AMD supports DDR5 only, Intel supports DDR4 and DDR5. Both are dual-channel with 89.6 GB/s bandwidth and both support ECC.

PCIe differs: AMD uses Gen 4 with 20 lanes (CPU only), Intel uses Gen 5 with 16 lanes (CPU only). Integrated graphics differ: AMD has Radeon 760M, Intel has UHD Graphics 730. Sockets differ: AMD uses AMD Socket FP8, Intel uses Intel Socket 1700. Market segments differ: AMD is Mobile, Intel is Desktop.

The AMD part has no launch MSRP recorded, an unknown part number, and an unlocked multiplier set to false. Both are Active in production status.

Architecture Differences

The AMD Ryzen Embedded 8640U belongs to the 8000 series, built on Zen 4 architecture under the Hawk Point codename. Its generation is listed as Ryzen Embedded (Zen 4 (Hawk Point)). The Intel Core 9 273PE uses the Bartlett Lake codename, with its generation listed as Core 9 (Bartlett Lake) and no architecture field populated. The foundries differ: TSMC fabricates the AMD chip at 4 nm, Intel fabricates its own chip at 10 nm.

The cache hierarchy reflects different design philosophies. AMD allocates 64 KB L1 per core and 1 MB L2 per core, with a 16 MB shared L3. Intel allocates 80 KB L1 per core and 2 MB L2 per core, with a 36 MB shared L3. Intel's per-core L2 is double AMD's, and its L3 is 2.25 times larger in absolute terms, though AMD's smaller core count means its shared cache per core is 2.67 MB versus Intel's 3 MB. No v-cache (3D V-Cache) is present on either chip.

Both processors support ECC memory and dual-channel memory buses with identical 89.6 GB/s bandwidth. AMD restricts memory to DDR5, while Intel supports both DDR4 and DDR5. The PCIe implementations differ by generation and lane count: AMD provides Gen 4 with 20 lanes, Intel provides Gen 5 with 16 lanes. Both are CPU-only lane counts. The AMD part integrates Radeon 760M graphics, the Intel part integrates UHD Graphics 730. The AMD chip is a mobile part on Socket FP8, the Intel chip is a desktop part on Socket 1700. The AMD chip's 28 W TDP aligns with its mobile positioning, while the Intel chip's 65 W TDP aligns with desktop use.

The Verdict

The recorded data points to a clear performance hierarchy. The Intel Core 9 273PE delivers benchmark scores across every test in the database, with an average score of 49,845 and a 90th percentile ranking. Its Cinebench R23 multi-core score of 31,288 and single-core score of 4,417, along with PassMark multithread score of 36,810 and single-thread score of 3,650, establish measurable throughput. The AMD Ryzen Embedded 8640U has no scores, a 50th percentile ranking, and an average score of zero, so no performance claims can be made from the database.

The Intel part's nearest rivals all fall within 1.2% of its average score, which places it in a competitive tier with the AMD Ryzen AI Max+ 388, Intel Core i5-14600KF, Intel Core i9-13980HX, and AMD Ryzen AI 9 HX PRO 370. The AMD Ryzen Embedded 8640U does not appear in that tier or any other tier based on recorded results.

For workloads that benefit from high core counts and thread scaling, the Intel Core 9 273PE is the only one of the two with evidence of capability. Its 12 cores, 24 threads, 36 MB L3 cache, 5.70 GHz boost clock, and PCIe Gen 5 support align with desktop tasks that demand sustained throughput. The AMD Ryzen Embedded 8640U, with 6 cores, 12 threads, 16 MB L3, 4.90 GHz boost, 28 W TDP, and mobile Socket FP8, targets embedded power-sensitive applications where low consumption matters more than peak performance. The data cannot support choosing the AMD part for speed, as no speed measurements exist. The selection depends entirely on whether the workload needs the Intel part's demonstrated performance or the AMD part's lower power envelope and embedded form factor.
