AMD Ryzen Embedded 8645HS vs Intel Core Ultra 7 270K Plus Comparison

Head-to-Head Benchmarks

The recorded data shows a complete performance disparity between these two processors. The Intel Core Ultra 7 270K Plus registered benchmark scores across every test in the database, while the AMD Ryzen Embedded 8645HS has no benchmark entries available. The Intel part holds wins in all measured categories, with the comparison defined entirely by its recorded results.

In Cinebench R15, the Intel Core Ultra 7 270K Plus scored 6656 points in the multi-core test and 354 points in the single-core test. The Cinebench R20 run produced a multi-core score of 24461 and a single-core score of 3453. Moving to Cinebench R23, the multi-core result reached 44253, while the single-core test delivered 2439. These scores place the processor at the 96th percentile among all CPUs in the database, indicating top-tier performance relative to the full range of recorded processors.

PassMark results reinforce the Intel processor's standing. The multithread score of 68574, single-thread score of 5068, and integer math score of 175986 all reflect strong throughput. The floating point math test recorded 229491, while data compression hit 804322 and data encryption reached 59097. Extended instructions scored 63506, random string sorting produced 96945, and the physics test registered 4064. The find prime numbers test delivered 615.

The AMD Ryzen Embedded 8645HS, by contrast, has an average benchmark score of 0 and no recorded entries in the database. Its percentile ranking sits at 50, which represents the median position, but this figure carries no weight without actual test data. The Intel processor's average benchmark score of 93785 stands as the only meaningful metric for comparison.

The nearest rivals for the Intel Core Ultra 7 270K Plus provide context for its positioning. The Intel Xeon 6520P holds an average score of 93786, effectively identical with a delta of 0%. The AMD EPYC 4564P scores 95183, putting it 1.5% ahead of the Core Ultra 7. The AMD EPYC 9175F reaches 95183 as well, or rather 95615, which is 1.9% higher. The AMD EPYC 4565P tops the group at 95764, a 2.1% advantage. These margins show the Intel Core Ultra 7 270K Plus trading blows with enterprise-class server parts, all within a narrow band of roughly 2% performance difference.

Where Each One Wins

The Intel Core Ultra 7 270K Plus wins in every benchmark category where data exists. Multi-core workloads show the clearest advantage, with Cinebench R23 multi-core at 44253 and Cinebench R20 multi-core at 24461. The PassMark multithread score of 68574 further confirms this strength. These results indicate sustained performance across heavily threaded applications such as rendering, simulation, and content creation.

Single-core performance also favors the Intel processor. The Cinebench R15 single-core score of 354, Cinebench R20 single-core score of 3453, and Cinebench R23 single-core score of 2439 demonstrate strong per-thread capability. The PassMark single-thread score of 5068 aligns with these results, suggesting responsive performance in lightly threaded tasks like legacy software and certain productivity applications.

Specialized workloads show particular strengths. The data compression score of 804322 is exceptionally high, indicating strong performance in archiving and file-handling operations. Data encryption at 59097 and extended instructions at 63506 both point to capable cryptographic and vectorized processing. Floating point math at 229491 and integer math at 175986 cover general computational density well. Random string sorting at 96945 reflects solid memory and sorting throughput. The physics score of 4064, while lower in absolute terms compared to other PassMark sub-tests, still represents a functional result for simulation workloads.

The AMD Ryzen Embedded 8645HS has no recorded wins because no benchmark data exists for it. The database shows zero entries for this processor, making any performance assessment impossible from measured results. Its 6 cores and 12 threads, Zen 4 architecture, and 5.00 GHz boost clock suggest it could handle moderate workloads, but without scores, no empirical claim can be made.

The Verdict

The data indicates that the Intel Core Ultra 7 270K Plus is the only processor in this comparison with measurable performance. Its 96th percentile ranking among all CPUs, average benchmark score of 93785, and comprehensive win across all recorded tests position it as a high-performance desktop processor. The 24 cores, 24 threads, and 5.50 GHz boost clock align with the observed multi-core and single-core results. The 36 MB shared L3 cache and 115.2 GB/s memory bandwidth provide architectural support for the recorded throughput.

The AMD Ryzen Embedded 8645HS, with no benchmark scores, cannot be evaluated on performance. Its 6 cores, 12 threads, and 5.00 GHz boost clock indicate a lower core count and slightly lower maximum frequency than the Intel part. The 16 MB shared L3 cache and 89.6 GB/s memory bandwidth are smaller in capacity and bandwidth respectively. The 45 W TDP suggests a power-efficient design, while the Intel processor's 125 W TDP indicates a higher power envelope. The AMD part targets the mobile segment with an FP8 socket, whereas the Intel processor is a desktop part on Socket 1851.

For users selecting between these two, the Intel Core Ultra 7 270K Plus delivers verified performance across all benchmark categories, with a launch MSRP of $299. The AMD processor offers no recorded data to support a performance-based choice. The Intel part's multiplier is unlocked, enabling overclocking, while the AMD part is locked. The Intel processor also uses PCIe Gen 5 with 20 lanes, compared to the AMD part's PCIe Gen 4 with 20 lanes. Based strictly on the database records, the Intel Core Ultra 7 270K Plus is the only defensible option for workloads requiring measured performance.
