AMD’s first mobile gaming CPU with 3D V-Cache, the Ryzen 9 7945HX3D, is set to debut on August 22 in the new “Asus ROG Strix SCAR 17 X3D” and has now also been spotted in Geekbench 5 and Geekbench 6 synthetic benchmarks. First time. In productivity applications, the mobile processor, mainly aimed at gamers, will be able to keep up with the regular Ryzen 9 7945HX and deliver gaming performance at a much higher level.

It’s no surprise that the Ryzen 9 7945HX3D can draw level with the regular Ryzen 9 7945HX in synthetic benchmarks like Geekbench 5 and Geekbench 6. As with the Ryzen 9 7950X3D, 8 of the 16 Zen 4 cores run at a full clock frequency of up to 5.4GHz in the boost. , and the base clock has also been reduced relatively slightly (- 200MHz vs. the R9 7945HX).

| Ryzen 5 7645HX | Zen 4 Dragon series |
6/12 | 4.0 GHz | 5.0 GHz | 38 MB | – | 45 watts + |
With CPUs’ technical specifications in mind, the results are in Geekbench5 And Geekbench 6 Not real. The AMD Ryzen 9 7945HX3D with an additional 64 MiByte L3 cache (“3D V-Cache”) lands exactly on par with the AMD Ryzen 9 7945HX without the stacked L3 cache.

Either way, the AMD Ryzen 9 7945HX3D is slightly faster than the Ryzen 9 7945HX, but that’s well within the benchmarking tolerance. In applications, both CPUs will perform at roughly the same level.

However, in gaming, the mobile gaming CPU, especially aimed at gamers, will flex its muscles, such as the Ryzen 9 7950X3D, Ryzen 9 7900X3D, and Ryzen 7 7800X3D, in terms of fps and fps per watt, represent the new CPU topping List of mobile phone manufacturers. AMD itself sees the Zen 4 CPU averaging 15 percent ahead of the Ryzen 9 7945HX without the additional L3 cache.

On Tuesday, August 22, the AMD Ryzen 9 7945HX3D will debut the Asus ROG Strix SCAR 17 X3D. By then at the latest, independent tests will show just how fast AMD’s Zen 4 CPUs with 3D V-Cache can be in the mobile segment.
