  1. I work for IMB R&D you
  2. Sony's RT secret sauce its a CELL2 design (2PPE + 32SPEs) at 3.5Ghz on a separate 3D die, its die size its around 60 mm2 on the 7nm process.
  3. Sony is trying really hard to get 24GB of unified HBM3 memory with bandwidth nearing 3TB/s to meet the demands of the heavily customized Navi chip, the Zen2 CPU and the CELL2
  4.  
  5. If HBM3 isn't ready in time, Sony is planning to go with a split memory pool: 18GB GDDR6 for the CPU & GPU monotheist die and 8GBHBM2 for the CELL2 (it needs low latency memory)
  6.  
  7. The GPU codenamed Kugoson its targeting 12 to 14 teraplots
