From Tom's Hardware: AMD is bringing 3D V-Cache, which powers some of the company's best CPUs, to gaming laptops. At ChinaJoy in Shanghai, the company announced the Ryzen 9 7945HX3D, which will launch on August 22 in the Asus ROG Strix Scar 17 X3D gaming laptop.
The chip is a 16-core, 32-thread processor with a boost clock up to 5.4 GHz (as of publication, AMD didn't list base clocks). It features 144MB of cache and has a TDP of at least 55W, though AMD suggests it can go higher. Like the rest of the Dragon Range HX-series lineup, the Ryzen 9 7945HX3D chip consists of a standard CPU for a desktop PC that's been crammed into a laptop chassis.
For those who haven't paid attention to the X3D desktop processors, the laptop one will work in a similar fashion. AMD applies 64MB of L3 cache to the CCD to reduce requests to system memory, saving precious milliseconds to keep framerates high by reducing the time it takes to complete instructions.
