AMD Ryzen Embedded 8645HS vs Intel Core Ultra 5 250K Plus Comparison

Head-to-Head Benchmarks

The recorded database contains benchmark scores for the Intel Core Ultra 5 250K Plus, while the AMD Ryzen Embedded 8645HS has no benchmark entries in this dataset. This makes a direct score-for-score comparison impossible. However, the available Intel data can be interpreted against its nearest rivals to establish a performance baseline, and the AMD part can be assessed qualitatively based on its specifications.

The Intel Core Ultra 5 250K Plus delivers a Cinebench R23 multi-core score of 30867 and a single-core score of 2261. In Cinebench R20, it records 18442 multi-core and 2603 single-core. The R15 results show 4640 multi-core and 328 single-core. These scores place the processor at the 93rd percentile among all CPUs in the database, with an average benchmark score of 66855.

Against its nearest rivals, the Intel part sits within a narrow band. The AMD EPYC 4465P averages 66925, which is 0.1% higher. The Intel Xeon 6515P averages 67006, 0.2% higher. The Intel Core Ultra 9 275HX averages 67469, 0.9% higher. Conversely, the Intel Core Ultra 5 250KF Plus averages 66159, which is 1.1% lower. These deltas indicate that the 250K Plus is competitive with server-class parts in aggregate scoring, trailing by less than one percent in most cases.

PassMark results for the Intel part show a multi-thread score of 51596 and a single-thread score of 4757. In specialized workloads, the data shows 568721 for data compression, 42144 for data encryption, 44565 for extended instructions, 486 for prime number finding, 162692 for floating point math, 125091 for integer math, 3494 for physics, and 69090 for random string sorting.

The AMD Ryzen Embedded 8645HS has no recorded benchmark scores, so its percentile ranking of 50 and average benchmark score of 0 reflect missing data rather than measured performance. The head-to-head comparison fields are empty, with zero wins recorded for either side. Without benchmark entries for the AMD processor, the database cannot quantify its standing relative to the Intel part.

The Verdict

The data supports a clear split based on workload expectations. The Intel Core Ultra 5 250K Plus is a measured performer with a 93rd percentile ranking and an average benchmark score of 66855. Its nearest rivals confirm that it trades places with high-end EPYC and Xeon parts within a one percent margin. The multi-core Cinebench R23 score of 30867 and PassMark multi-thread score of 51596 indicate strong parallel throughput. The single-core R23 score of 2261 and PassMark single-thread score of 4757 show capable per-thread performance as well.

The AMD Ryzen Embedded 8645HS cannot be positioned from benchmark data because none exists in the database. Its specifications, however, place it in a different class. It uses 6 cores and 12 threads, whereas the Intel part uses 18 cores and 18 threads. The AMD processor has a base clock of 4.30 GHz and a boost clock of 5.00 GHz, while the Intel part has a base of 4.20 GHz and a boost of 5.30 GHz. The AMD part carries a 45 W TDP and targets mobile systems, while the Intel part carries a 125 W TDP and targets desktops.

Who should pick which? From the data alone, the Intel Core Ultra 5 250K Plus is the only option with verified performance metrics. Its aggregate scores and percentile rank make it suitable for workloads that benefit from 18 cores and high throughput. The AMD Ryzen Embedded 8645HS, based strictly on its listed specifications, offers a lower core count and a much lower TDP, which suggests an efficiency-oriented mobile design. The database cannot confirm its performance, so any selection between the two must rely on the Intel measurements and the AMD specification profile.
