他之前在 Intel 參與 Pentium3 到 core i 的設計,目前已離職
投影片中提到幾件事:
* 現在 Intel 失去了專注,沒在消費者/server端推出適合的產品
* 併購來的團隊都沒用
* 在筆電CPU 加上 AVX512 只是浪費空間,沒多少筆電用戶會用到
* 塞了一堆無用又耗電的功能, 所以 core 數量輸給 ARM/AMD
* Skylake 架構專注在單一核心效能, Ryzen 則是靠 SMT 提高 CPU 區塊使用率
(大概 13:00~22:00 談架構設計,要有點專業才能懂orz)
* 現在 Intel 能維持佔有率只是運氣好,AMD 沒有能力吃下更多市場
* 世界已經變了,不再是同一套架構打天下的時代,沒有那麼多人需要 SIMD
那些空間客製化更多 core 才對
* 重金請來有MBA的管理者沒用
* 對外公關該談更多技術,別學 Apple
