AMD Ryzen 9 7945HX "Dragon Range" processor has better multi-core performance with less power consumption than Intel Core i9-13980HX

The colleagues from Notebookcheck have tested the 16-core Zen4 Raphael and tried out the brand-new ASUS ROG Zephyrus Duo. Today’s review focuses only on CPU performance, with more details on gaming performance to follow later (although they have already released a teaser).

According to the combined results, the flagship Ryzen 9 7945HX is almost as fast as Intel’s flagship Core i9-13980HX CPU in the single-core test and just as fast in the multi-core test. The two processors swap places in both ratings with a gap of up to 5%. It is worth noting that ROG Zephyrus Duo is equipped with DDR4-4800 memory, while MSI TITAN GT77 HX 13VI (the platform for Intel HX series) uses faster DDR5-5600 memory.

The AMD CPU has 16 cores and 32 threads, which are all “BIG” cores, unlike Intel’s hybrid Core/Atom architecture. This means that the AMD CPU is faster in the multi-core test despite the same number of threads, which should not surprise anyone. It is important to note that the Ryzen 9 7945HX consumes less power than the Intel 13th Gen Core-HX series. A peak value of 120W was measured, while Intel CPUs can consume up to 150W. The tester even tested both CPUs with the same power limit and concluded that the Zen4 architecture is 22% faster when both CPUs are limited to 120W. The CPU is also significantly faster than the last-generation Ryzen 9 6900HX Rembrandt Zen3+ SKU, as tested with the same ASUS ROG Duo laptop from 2022 (the title on this slide is incorrect):

The website also offers a very brief look at gaming performance, with more tests to follow. Higher performance and single-core frequency on Intel CPUs result in up to 7% better gaming performance. Both the MSI and ASUS systems support GeForce RTX 4090 GPUs with up to 175 W TGP, but there could be other things at play, which will be explained in the full review.

Die Kollegen von Notebookcheck haben den 16-Kern Zen4 Raphael getestet und das brandneue ASUS ROG Zephyrus Duo ausprobiert. Der heutige Testbericht konzentriert sich nur auf die CPU-Leistung, weitere Details zur Spieleleistung folgen später (obwohl sie bereits einen Teaser veröffentlicht haben). Das Flaggschiffmodell Ryzen 9 7945HX ist laut den kombinierten Ergebnissen zufolge im Single-Core-Test fast genauso (den ganzen Artikel lesen...)
