We already knew what a beast the Dragon Range AMD Ryzen 9 7945HX APU is after extensively testing it against rivals like the Raptor Lake Intel Core i9-13980HX and i9-13950HX. Now the Zen 4 processor has appeared in the PassMark benchmark database, with three samples that give amazing results but with a high error rate. The laptop processor with an RDNA2-based AMD Radeon 610M iGPU achieved a single-threaded test score of 4,405 and a CPU Mark multi-test suite score of 61,985. The website lists the Ryzen 9 7945HX as having a maximum TDP of 55W, but the 16-core, 32-thread part is configurable up to 75W.
Despite the higher boost clock of 5.6 GHz (Ryzen 9 7945HX: 5.4 GHz), the Intel Core i9-13980HX is left behind in the single-thread test. Its 4,398 score is close to Team Red’s Dragon Range chip, but this is a processor with a maximum turbo output of a whopping 157W (although PassMark records a maximum of 55W here). While the AMD Ryzen 9 7945HX only has a tiny +0.16% advantage in the single-thread duel, it rolls out a huge +26.6% lead over the Raptor Lake processor in CPU Mark (61,985 vs. 48,954 ). In fact, the Zen 4 APU is so powerful that it can be compared to a modern Intel desktop processor – the new i9-13900KS no less.
There have been many instances where laptop processors have overtaken mainstream or previous generation desktop parts, but this is Dragon Range Mobile vs. Raptor Lake Desktop. Not surprisingly, the Intel Core i9-13900KS, with its peak clock speed of up to 6.0 GHz and a potential for 253 W TDP (recorded at 125 W at PassMark), has a reasonable lead over the Ryzen 9 7945HX in the single-threaded test can get out: 4,809 vs 4,405 or +9.17%. However, this mobile Zen 4 APU can still outperform a desktop i7-13700K in this particular discipline, and it’s even more of a competitor in the CPUMark test suite.
With its impressive score of 61,985 in the Multi test, the AMD Ryzen 9 7945HX comes within reach of Intel’s 24-core desktop processor. With a score of 62,166, the performance-hungry i9-13900KS desktop processor is only +0.29% ahead of a significantly more efficient mobile processor. There might be some who complain about comparing a mobile chip to a desktop part, but AMD has produced such an impressive device in the Ryzen 9 7945HX that it only seems fair at the moment. Also remember that this mighty laptop-class processor comes with 64MB of L3 cache.
