前段时间海力士公布HBM2e研发成功，今天就看到AMD的新卡了，听说intel的FP64也在49T，看来此言不虚。显存带宽 3.2 TB/s, L2带宽 6.96T(MI250)
目前已知的是，AMD Instinct MI200 将为三台顶级超算提供支持，包括美国百亿亿级 Frontier 系统、欧盟 pre-exascale LUMI 系统、以及澳大利亚千万亿级 Setonix 系统。

一些担忧

AMD和Intel都使用了SIMD来提高整体吞吐量，而NVIDIA在Volta之后反其道而行之通过线程(PC)来使得更好更简单的性能收益，尤其是if else。
AMD这一波抢了intel一手啊哈哈哈哈，首发49T fp64的惊喜没了，估计近期就会预告公布了。
