AMD Ryzen 9 7945HX3D Spotted: 3D V-Cache Paired with the RTX 4090 in Gaming Notebooks

AMD’s 3D V-Cache is headed to notebooks later this year, bringing no-compromise gaming performance for the fastest mobility GPUs. We know of at least one mobile V-Cache processor, the Ryzen 9 7945HX3D, currently being prepped for ASUS’s upcoming ROG Strix Scar 17. Featuring 16 Zen 4 cores and 128MB of L3 cache, this chip will be paired with NVIDIA’s GeForce RTX 4090 mobile and a potent thermal solution. The configuration will be exclusive to ASUS ROG notebooks at launch.

A couple of Geekbench benchmarks confirm the existence of the Ryzen 9 7945HX3D. It is a chiplet-based design with 16 cores, a base clock 2.30GHz, and a peak frequency of 5.3 to 5.4GHz. One of the compute dies features the standard 32MB of L3 cache, while the other consists of the 64MB 3D stacked cache die for a total of 96MB.

The Ryzen 9 7945HX3D has 32GB of quad-channel DDR5-4800 memory and a GeForce RTX 4090 mobile. In the Geekbench tests, it scores roughly the same as the 7945HX, which isn’t surprising since V-Cache has limited use-case scenarios, most notably gaming. Geekbench isn’t a good indicator of gaming performance and often tends to assign excessive importance to the memory sub-system.
