In May last year, AMD began talking about its plans for Zen 4 mobile. It announced it was prepping some heavy-hitting silicon dubbed Dragon Range. AMD boasted this family of processors would allow it to achieve “mobile gaming dominance.” Those are fighting words, and now we finally have a benchmark that shows AMD wasn’t just talking smack. A new PassMark result has arrived for the second-tier Ryzen 9 mobile CPU, and it’s clearly a potent chip. In this one test, it has landed at the very top of PassMark’s mobile benchmark leader’s board. It not only trounced Intel’s Alder Lake mobile, but it’s also 90% faster than the flagship Zen 3 mobile CPU.
The Ryzen 9 7845HX is a 12-core, 24-thread Zen 4 CPU with RDNA 2 graphics. This is a 55W part with a base clock of 3GHz and a boost clock of 5.2GHz. Its TDP is configurable up to 75W or as low as 45W. It’s packing 76MB of L2 and L3 cache, which is part of AMD’s Dragon Range strategy to offer more cores, threads, and cache than Intel’s offerings. In PassMark the 7845HX scored a blistering 46,791, dethroning Intel’s Core i9-12900HX. That score is 31% higher than Intel’s CPU and 90% higher than the Ryzen 9 6900HX. It is also 78% higher than the recently-launched Apple M2 Max. However, in single-thread performance, Apple’s newest SoCs are still top-of-the-charts.
What’s interesting is this isn’t even the flagship CPU in the family. The 16-core, 32-thread Ryzen 9 7945HX is waiting in the wings, as HotHardware notes; that chip will boost to 5.4GHz. However, AMD hasn’t officially launched any of these CPUs yet via its partners. As such, even this 12-core benchmark is technically a leak, so take it with a grain of salt. Still, it’s an impressive outing for Zen 4 mobile.
It indicates Intel will have a fight on its hands when it eventually launches Raptor Lake mobile. Still, Intel is seemingly well prepared with its Core i9-13980HX CPU. Intel will be able to best AMD on core count and tie it on thread count. Whereas the 7945HX has 16 cores and 32 threads, Intel’s hybrid approach allows for 24 cores (8p cores + 16e cores) and 32 threads. Intel also allows a maximum boost clock of 5.6GHz, compared with 5.4GHz for the 7945HX. This CPU has a maximum TDP of 157W, so it’ll be going into desktop replacement laptops.
Both Raptor Lake mobile and Dragon Range are expected to be launching soon in laptops from the usual suspects. This will net us more reliable numbers from both camps. It’ll be an interesting matchup as Dragon Range is the first mobile CPU family with a chiplet design. Like its desktop CPUs, AMD’s 12-and-16 core CPUs will feature dual CCDs along with an I/O chip, both built by TSMC.
