AMD Ryzen Embedded 8640U vs Intel Core Ultra 7 270K Plus Comparison

AMD Ryzen Embedded 8640U vs Intel Core Ultra 7 270K Plus is a comparison that pits a low-power mobile processor designed for embedded systems against a high-performance desktop part aimed at enthusiasts. The data available in the database is lopsided: the Intel Core Ultra 7 270K Plus has a full suite of benchmark results, while the AMD Ryzen Embedded 8640U has no recorded scores. This disparity in data forces the analysis to rely on the architectural and specification differences between the two chips, along with the performance metrics of the Intel part relative to its nearest rivals.

Head-to-Head Benchmarks

The database contains no head-to-head benchmark results between these two processors, and the AMD Ryzen Embedded 8640U has no recorded benchmark scores of its own. This means a direct performance comparison is impossible from the available data. What is possible is an examination of the Intel Core Ultra 7 270K Plus’s recorded scores, which show a strong performer across multi-threaded and single-threaded workloads.

In Cinebench R23, the Intel Core Ultra 7 270K Plus scores 44,253 points in multi-core and 2,439 points in single-core. The multi-core result places it in the 96th percentile of all CPUs in the database, indicating it outperforms the vast majority of processors tested. In Cinebench R20, the scores are 24,461 multi-core and 3,453 single-core. The Cinebench R15 results show 6,656 multi-core and 354 single-core.

PassMark results for the Intel chip are consistently strong. The multithread score is 68,574, while the single-thread score is 5,068. Integer math scores 175,986, floating point math scores 229,491, and extended instructions score 63,506. Data compression scores 804,322, and data encryption scores 59,097. Find prime numbers scores 615, physics scores 4,064, and random string sorting scores 96,945.

The Intel Core Ultra 7 270K Plus’s nearest rivals in the database are all server-class processors. It scores an average benchmark score of 93,785, which is essentially tied with the Intel Xeon 6520P at 93,786 (0% delta). It trails the AMD EPYC 4564P, which averages 95,183, by 1.5%. It is also behind the AMD EPYC 9175F by 1.9% (95,615 average) and the AMD EPYC 4565P by 2.1% (95,764 average). These narrow margins indicate that the Core Ultra 7 270K Plus competes directly with high-core-count server parts, despite being a desktop processor.

The Verdict

The Intel Core Ultra 7 270K Plus is the only processor in this comparison with measurable performance data, and it demonstrates strong multi-threaded capabilities. Its 24 cores and 24 threads, combined with a 5.50 GHz boost clock, yield benchmark scores that sit within 2.1% of several AMD EPYC server processors. For anyone seeking a desktop CPU with high multi-threaded throughput, the data clearly supports this Intel part.

The AMD Ryzen Embedded 8640U, with 6 cores and 12 threads and a 28 W TDP, is a fundamentally different class of processor. Its lower core count and power envelope suggest it is intended for compact, low-power embedded applications rather than high-performance desktop use. Without any benchmark scores in the database, no performance assessment can be made for this chip. Users requiring raw compute throughput should select the Intel Core Ultra 7 270K Plus, while those needing a low-power embedded solution would consider the AMD part based on its specifications alone, not its measured performance.

Architecture Differences

The two processors use fundamentally different architectures. The AMD Ryzen Embedded 8640U is built on Zen 4 architecture, codenamed Hawk Point, and belongs to the Ryzen Embedded 8000 series. It is manufactured on a 4 nm process at TSMC, with 25,000 million transistors on a 178 mm² die. The Intel Core Ultra 7 270K Plus uses the Arrow Lake Refresh codename, part of the Core Ultra Series 2, and is built on a more advanced 3 nm process, also at TSMC. It packs 17,800 million transistors on a larger 243 mm² die.

Cache hierarchies differ significantly. The AMD chip has 64 KB of L1 cache per core, 1 MB of L2 cache per core, and 16 MB of shared L3 cache. The Intel chip has 192 KB of L1 cache per core, 3 MB of L2 cache per core, and 36 MB of shared L3 cache. The Intel processor’s larger per-core caches and bigger L3 pool give it a structural advantage in workloads that benefit from larger working sets.

The AMD processor integrates Radeon 760M graphics, while the Intel chip includes Arc Xe-LPG Graphics with 64 execution units. Both support DDR5 memory and have ECC memory capability, which is notable for embedded and server-like applications. The AMD part supports PCIe Gen 4 with 20 lanes, while the Intel part supports PCIe Gen 5 with 20 lanes, offering double the bandwidth per lane for compatible devices.

Specification Differences

The core and thread counts differ substantially. The AMD Ryzen Embedded 8640U has 6 cores and 12 threads, while the Intel Core Ultra 7 270K Plus has 24 cores and 24 threads. The Intel chip has no hyperthreading, so its thread count equals its core count, whereas the AMD chip uses simultaneous multithreading to double its thread count.

Base clocks are close: the AMD chip runs at 3.50 GHz, and the Intel chip at 3.70 GHz. Boost clocks show a larger gap, with the AMD chip reaching 4.90 GHz and the Intel chip hitting 5.50 GHz. The TDP difference is massive: the AMD processor is rated at 28 W, while the Intel processor is rated at 125 W. This reflects their different market segments, with the AMD chip classified as mobile and the Intel chip as desktop.

Memory bandwidth also differs. The AMD processor has a dual-channel memory bus with 89.6 GB/s bandwidth, while the Intel processor’s dual-channel bus delivers 115.2 GB/s. The Intel chip has an unlocked multiplier, allowing overclocking, while the AMD chip does not. The AMD processor uses AMD Socket FP8, and the Intel processor uses Intel Socket 1851.

The Intel Core Ultra 7 270K Plus has a launch MSRP of $299. The AMD Ryzen Embedded 8640U has no recorded launch MSRP. The Intel chip has a part number of SA4V6, while the AMD chip’s part number is listed as unknown. The release dates differ, with the AMD chip released on April 1, 2024, and the Intel chip on March 10, 2026.
