AMD 4800U ...(恕刪)
Renoir APU 核心架構還是 CCX 設計喔
(4MB $ per CCX，最大 8MB)
只是和 Vega iGPU 做成一顆 150mm^2 的 Die
和桌機的 Ryzen 3000 不同的是
Renoir 整顆都是 TSMC 7nm 工藝製作
沒有獨立的 IO Die (GF 12nm)
“AMD stated that the Zen 2 design in this chips follows the same CCX layout as the desktop hardware, which means the 8 cores are split into two CCX units which communicate over the internal infinity fabric. AMD has also adjusted the L3 amount, to 4 MB per CCX, which is half that of the consumer desktop line.”
