AMD Ryzen 9 7945HX Over 20% Faster than Intel’s Core i9-13950HX with Fewer Cores: 16 vs. 24 Cores

A Cinebench R23 benchmark of the Ryzen 9 7945HX has surfaced (via: HXL), highlighting extraordinary gen-over-gen gains. Featuring a chiplet design with two eight-core Zen 4 CCDs (16 cores in total), the Dragon Range flagship boasts a boost clock of 5.4GHz alongside 64MB of L3 cache. The Ryzen 9 7945HX has a stock TDP of 55W which can be increased to 75W on enthusiast gaming notebooks.

We recently tested the Razer Blade 16 featuring the Intel Core i9-13950HX and the GeForce RTX 4090 mobile and were quite impressed by the performance. The Ryzen 9 7945HX, however, completely dominates the 24-core Raptor Lake-HX part despite featuring fewer cores (16).

In the multi-core Cinebench R23 benchmark, the Ryzen 9 7945HX is over 20% faster than the Intel Core i9-13950HX, beating its predecessor, the Ryzen 9 6900HX, by a huge margin of 120%. It is also a remarkable 68% faster than the Core i9-12900HX, which until recently, was the fastest notebook processor.

The Intel Raptor Lake-HX flagship fares better in the single-core benchmark. It holds a narrow lead of 6% over the Ryzen 9 7945HX in terms of single-threaded performance. These results make us question the usefulness of the additional E-cores on the Raptor Lake chips. If a 16-core part with slightly lower single-threaded performance beats a 24-core (hybrid) chip, it might have been better to include 16 P-cores rather than a large cluster of “inefficient” E-cores.
