The crunch for space at TSMC must be much worse than we realize for AMD to still use Vega which is made at GlobalFoundries.
With that said, this is some impressive logistical and supply chain juggling on AMDs part.
- ChuckNorris89 6y agoZen3 and Zen2 are monolithic. The Vega GPU is on the same die as the CPU, not a separately fabbed part.
- Tsarbomb 6y agoOh damn you are correct. Okay, then I don't understand the continued use of Vega unless RDNA2 doesn't scale well to low voltage yet.
- pedrocr 6y agoMaybe they skipped 7nm and are going straight to 5nm for RDNA2 in CPUs. Zen4 based mobile chips will probably be a very interesting release.
- enragedcacti 6y agoMy understanding is that there is little benefit in upgrading the iGPU to RDNA2 because of the bandwidth limitations imposed by sharing ddr4 with the CPU. We should see some real improvements in iPGU performance once ddr5 rolls out late 2021/early 2022.
- kllrnohj 6y agoProbably just a no need type of thing. The Vega 8 is plenty fine for normal desktop usage, and they already had it integrated into Zen2. So just plop in the new Zen3 CPU and call it a day? Which is for comparison basically what they did on the desktop side. The Ryzen 5000 desktop CPUs use the exact same IO die as the Ryzen 3000 line.
- cbozeman 6y agoYour initial idea is still correct though, the crunch for space at TSMC is truly awful.
