Intel Labs experimented with many low power cores vs. fewer, faster high power cores back around 2009-2010. https://www.zdnet.com/article/experimental-intel-chip-could-... Programmability is always the biggest issue, and that's not really a chicken-and-egg problem because decades of research have gone into writing compilers and languages for massively parallel machines -- it's just hard, some would say intractable (and local memories tend to make programmability issues worse.) There are niche or embarrasingly-parallel problems that will run great. But it's hard to sell hardware that will solve only some of your problems well. And GPUs have taken over for many of those very regular problems as well. |
