AMD Ryzen 9 7945HX3D Mobile V-Cache CPU up to 38% Faster than Intel’s i9-13980HX, 50% More Power Efficient

The Ryzen 9 7945HX3D will remain exclusive to ASUS notebooks for now. With a consistent lead over Intel's Core i9-13980HX, it is faster, more efficient, and all-around a better gaming chip.

AMD’s first mobile 3D V-Cache processor launches with 128MB of L3 cache (+64MB) and a dual-chiplet design in the coming weeks. Barring the 3D stacked SRAM on one of the compute dies, the 16-core chip is identical to the 7945HX. The non-V-Cache die has a boost clock of 5.4GHz, the same as the latter. Both come with a TDP limit of around 100W, making them twice as efficient as the Core i9-13980HX, Intel’s 13th Gen Raptor Lake mobile flagship.

The Ryzen 9 7945HX3D will remain exclusive to ASUS notebooks for now. Notebookcheck tested the ROG Strix SCAR 17 X3D, recording impressive gains over the 7945HX and a consistent lead over Intel’s Core i9-13980HX. Despite consuming 70% to 80% more power, the latter is slower in nearly every game, with deltas varying from 19% to 38%.

The ASUS ROG Strix Scar 17 powered by the 7945HX3D is 19% faster than the Core i9-13980HX powering the Strix Scar 18. The Ryzen 9 7945HX variant is 33% slower than the new V-Cache chip, with a 20% deficit compared to the latter.

Cyberpunk 2077 has always performed better on Ryzen CPUs. Consequently, the Core i9-13980HX finishes last, granting the Ryzen 9 7945HX and the 7945HX3D a 12% and 13% lead, respectively.

Shadow of the Tomb Raider is one of the more CPU-intensive games. The Core i9-13980HX throttles hard on the Strix Scar 18, averaging 144 FPS. The Ryzen 9 7945HX3D is 89% faster in this game than Intel’s fastest mobile processor.

In Far Cry 5, the Core i9-13980HX is 8% faster than the Ryzen 9 7945HX, while the 7945HX3D holds the top spot with a lead of 38% over the former.
