AMD announced its Q1 earnings reports the other day, and while it didn’t exactly divulge the sales figures for each processor lineup, we have a bit of info to work with. Sony has announced that it has sold 7.8 million PS5 consoles in the last six months and we already know the die size and wafer size of TSMC’s N7 wafers. Similarly, the Xbox Series X|S consoles have sold around 4-4.5 million units to date while the Ryzen 5000 processors were able to sell a million units in Q4 2020 and we’re going with 1.5 million units for Q1. Similarly, the mobile Ryzen APUs should have sold around 500-700K units in the last six months (on the high side, I know), while Big Navi sales should have reached close to 500K GPUs during the same time frame.
Die-Sizes for various SoCs:
- PS5: 308mm2
- Xbox Series X: 360mm2
- Xbox Series S: 197mm2
- Zen 3 chiplet: 81mm2
- Renoir/Cezanne: 156mm2/175mm2
- Navi 21: 520mm2
Per wafer area= 42,000mm2 (approx, with defects factored in).
- PS5: 137 dies per wafer
- Xbox Series X: 117 dies per wafer
- Xbox Series S: 214 dies per wafer
- Zen 3 chiplet: 520 dies per wafer
- Renoir/Cezanne: 256/240 (248 avg) dies per wafer
- Navi 21: 81 dies per wafer
Wafers dedicated to each processor:
- PS5: 7.8 million dies at 137 per wafer ~56,934 wafers.
- Xbox Series X: 3 million dies at 117 per wafer ~ 25,641 wafers
- Series S: 1.5 million dies at 214 per wafer ~ 7,009 wafers
- Zen 3: 3,365 (R5/R7) + 2,884 (R9)= 6,249 wafers ; (1.75 million R5/R7, 525K R9 SoCs)
- Zen 2: 3,000-4,000 wafers (approx)
- Renoir/Cezanne: 500K dies at 248 per wafer ~ 2,016 wafers
- Navi 21: 500K dies at 81 per wafer ~ 6,172 wafers
This means that the PS5 and Xbox series consoles got nearly 90,000 7nm wafers from AMD’s capacity at TSMC while the Ryzen processors got just under 10,000 wafers. The Navi 21 lineup (RX 6800, 6900) got a bit over 5,000 wafers on account of the large die size but this is likely an exaggeration considering the GPU supply, but it should make up for excluding the older GCN-based products and the older Ryzen CPUs. Overall, this brings the total wafer count for the consumer chips to around 17-19K, a far cry from the 90K wafers diverted to the console business.
