AMD won’t be bringing its Zen 3D architecture to mobile designs for the time being. This news was shared by WCCFTech along with the details of the next-gen Ryzen 6000 “Rembrandt” mobile processors. According to the outlet, the Ryzen 9 6900HX will be the top-end SKU from the Rembrandt family with 8 cores and 16 threads. The CPU core architecture will be mostly identical to Cezanne, featuring 4MB of L2 and 16MB of L3 cache.
The GPU will be the primary change. AMD will be introducing its RDNA 2 graphics architecture to mobile SoCs with up to 12 CUs or 768 shaders. The Steam Deck with its Van Gogh APU packs a similar GPU paired with LPDDR5 but uses the older Zen 2 cores instead. The inclusion of 50% more shaders coupled with super-fast DDR5/LPDDR5 memory and higher boost clocks will confer a phenomenal performance boost to the accompanying iGPU, beating even the lower-end dGPU offerings.
Coming to the process node, the Ryzen 6000 APUs will leverage TSMC’s 6nm (N6) node which features optimized libraries, improving boost clocks and/or power efficiency. The Ryzen 9 6900HX is going to boast a max operating clock of 4.6GHz, the same as the 5900HX, albeit at a lower power draw.
Unfortunately, AMD won’t be bringing its 3D V-Cache architecture to its mobile offerings anytime soon. We’re likely to see 3D stacked L3 cache in the mobile segment no sooner than Zen 5. That’s also when Team Red plans to introduce hybrid core designs such as Strix Point and Granite Ridge for the consumer market.
