This seems two sides of the same coin; of course you can extract higher performance with lower coupling.
I don’t think the Xeon Phi was given a fair chance; they did two iterations on the idea before canning it. NVidia has been doing video cards forever.
- bonzini 8y agoXeon Phi's origins are in Larrabee. They sold two iterations, but they had several more in house.
- pjmlp 8y agoI sat on an Intel session at GDCE 2009 about introduction to Larrabee programming and how it would take over the GPU programming world for game developers. Making it a niche product only available to a selected few, instead of mainstream GPGPUs, meant most of us hardly cared about it.
