  • Their last “high end” before the RX 6900 XT was the Vega VII and before that Vega 64, yeah they only were able to compete with the RTX 2080 and GTX 1080 respectively but so does the RX 7900 XTX that can only compete with the RTX 4080…

    PS.: Also the high end AMD GPU before Vega 64 was the R9 Fury X (R9 390X was a 290X refresh that launched in the same period), that was quite competitive with the GTX 980 Ti but it’s 4 GB of HBM and and the necessity to be water cooled limited its sales…



  • Technically yes, but AMD had used monolithic dies for their APUs for years and trying to add cache on top of a bigger piece of silicon than a CPU chiplet would need a redesign at least and it would jack up prices quite significantly and most likely we would only see a single SKU with it.

    I’d guess a better alternative would be a chiplet based APU that’s similar to Navi 32/31 design (GPU die surrounded by cache chiplets). It would be quite malleable, you could add a Zen X/Zen XC chiplet (or a hybrid of both that you can add 3D V-Cache on top if you wish), a GPU chiplet and a cache chiplet to keep more data to the GPU so it’s less reliant on RAM bandwidth.

    Probably AMD may do that in the near future with a RDNA 4/5 APU, the main problem is power consumption (Transferring data between chiplets consumes more power than a monolithic chip with all of its components in a single die) and that would be a significant downside for mobile devices, that’s why they haven’t made a chiplet based APU yet and it’s easier to just recycle/resell any laptop APU as a desktop one.
