The Verdict
The data indicates that the Intel Core Ultra 9 275HX is the stronger processor for multi-threaded workloads. It wins 16 of 17 head-to-head benchmarks, including all multi-core Cinebench tests, all PassMark tests except one, and the PassMark single-thread test. Its 24 cores and 24 threads, combined with a 3 nm process, deliver a 60.2% lead in Cinebench R15 multi-core, a 53.2% lead in Cinebench R20 multi-core, and a 37.6% lead in Cinebench R23 multi-core over the Core i7-14701E.
The Core i7-14701E wins only Cinebench R23 single-core, with a 42.2% lead. This single result does not establish a pattern, as the Core Ultra 9 275HX wins the other single-core tests: 5.7% in R15 single-core and 53.2% in R20 single-core. The Core i7-14701E also trails in PassMark single-thread by 8.7%.
For users selecting between the two, the choice depends on workload. The Core Ultra 9 275HX is the clear choice for rendering, data compression, encryption, and floating-point math. Its 94th percentile ranking among all CPUs confirms this. The Core i7-14701E, with its 83rd percentile ranking, offers a narrow single-core advantage in one specific test but falls behind in nearly every other metric. The Core Ultra 9 275HX also has a lower TDP of 55 W versus 65 W, despite delivering higher performance. The Core i7-14701E's only advantages are ECC memory support and DDR4 compatibility, both absent from the Core Ultra 9 275HX.
