The newer Arrow Lake processor doesn't trail behind CPUs with more cores, and surprisingly delivers results that are on par with them.
Intel Core Ultra 7 251HX Delivers Slightly Higher Single and Multi-Core Performance Than Ultra 7 255HX and Ultra 7 265HX in PassMark
The Intel Core Ultra 7 251HX is one of the latest additions to the Arrow Lake-HX family, if you remember our recent posts on the processor. Previously, it was spotted in a Cinebench R23 benchmark, where it was delivering superior results at sub-100W TDPs. The processor launched nearly two months ago and sits between the Core Ultra 5 245HX and Core Ultra 7 255HX, bringing a core configuration of 18 cores.
Typically, one would expect that, since it offers two fewer cores than the Intel Core Ultra 7 255HX, it should be slower, which is true as far as Cinebench R23 results are concerned. However, the latest leaked PassMark results demonstrate that the 251HX trades blows with the 255HX and 265HX despite having fewer cores in both single and multi-threaded performance.
In single-core, the 251HX delivered 4,666 points, offering a 2-3% uplift over the Ultra 7 255HX and 265HX. In the multi-threaded tests, the processor delivered 48,713 points, which are slightly higher than the MT numbers for the 255HX and 265HX. Keep in mind that only two samples of the Ultra 7 251HX have been registered till now, and the more samples we include, the more accurate the results will be.
Still, it's surprising to see Intel's new offering doesn't need that many cores to deliver nearly 50,000 points in a multi-threaded PassMark test, and it's a great chip for mainstream high-performance laptops, considering it works at the same 55W TDP as the 255HX and 265HX, and also brings much better power efficiency scaling at sub-100W.
