AMD 3D V-Cache CPUs are coming to laptops, and they'll contend for the gaming crown

pcgamer.com:

AMD is reportedly preparing to bring its 3D V-Cache technology to its Zen 4 mobile CPUs, and it's about damn time! V-Cache equipped chips have been available for a long time in desktop and server form, but until now, we haven't seen the tech make it into an AMD mobile chip.

According to a tweet (or is that an X, or whatever) from @9550pro, the first chip is the Ryzen 9 7945HX3D. It will feature in an upcoming Asus ROG Scar notebook. The chip features 16 Zen 4 cores and a total of 128MB of L3 cache. This is made up of 32MB on each of the two chiplets, plus an additional 64MB of stacked cache.

This chip will sit at the top of AMD's mobile CPU range, so expect it to feature in flagship desktop replacement machines with the best GPUs. Battery life and mobility won't be the selling point of these systems. It'll be all about performance, and there's every chance notebooks with this chip will be the fastest on the market.

If mobile V-Cache chips prove to be successful for AMD, there's no reason to doubt we'll see the tech trickle down to the worldlier models. 8-core or 6-core V-Cache equipped chips should offer excellent gaming performance, and with any luck, they won't cost too much and deliver good battery life too, which is a trait of AMD's mobile CPUs.

I've been surprised not to see AMD release V-Cache models for the notebook market. It is a natural fit given the characteristics of mobile chips. They don't have the TDP or thermal budget of desktop chips, and they're clocked lower, meaning more L3 cache should be even more advantageous in games that would otherwise require power guzzling raw clock speeds to maximize performance.
