AMD Ryzen 9 PRO 8945HS vs Intel Core 7 251E Comparison

The Verdict

The AMD Ryzen 9 PRO 8945HS and Intel Core 7 251E target fundamentally different segments despite both being active production parts. The AMD part is a mobile processor with 8 cores and 16 threads, built on TSMC's 4 nm process with Zen 4 architecture. The Intel part is a desktop processor with 24 cores and 32 threads, built on Intel's 10 nm process with Bartlett Lake architecture. The data shows the AMD chip is the stronger choice for single-threaded and light-threaded workloads, where its higher base clock of 4.00 GHz and boost clock of 5.20 GHz give it a decisive edge over Intel's 2.10 GHz base and 5.60 GHz boost. The Intel chip, however, offers substantially more cores and threads, which matters for heavily parallel workloads that can use all 24 cores and 32 threads.

Benchmark results for the AMD part place it at the 88th percentile among all CPUs, with an average benchmark score of 41963. Its nearest rivals include the Intel Core i7-14700T at 41914 (0.1% behind), the AMD Ryzen 5 7400 at 42055 (0.2% ahead), the Intel Core i7-12850HX at 41779 (0.4% behind), and the Intel Core 7 251TE at 41650 (0.8% behind). The Intel Core 7 251E itself has no recorded benchmark scores in the database, so direct head-to-head comparisons rely on the AMD part's measured results and the architectural differences.

Users who need a mobile processor with strong per-core performance and integrated graphics should choose the AMD Ryzen 9 PRO 8945HS. Users who need a desktop processor with maximum core count and thread count for multi-threaded throughput should choose the Intel Core 7 251E. The Intel part's launch MSRP is $384, which appears once in the database. The AMD part has no recorded launch MSRP.
