I'm certainly hopeful this will lead somewhere useful. Intel tried with Larrabee but apparently couldn't get the perf they wanted, especially with comparisons to GPUs
It would be great to know what the trade-offs are with this architecture
- alexnewman 10y agoyou mean xeon phi. I think it's still around. It is plenty fast, but not much better tdp than a gpu (which are commodity (read this as cheap)).
- deadgrey19 10y agoXeon Phi is around and used in various financial computations. The problem with GPUs is not TDP, but programming flexibility. Programming a GPU is very hard to do well for generic computations, whereas x86 like CPUs have millions of programmers who can do a pretty decent job.
- CyberDildonics 10y agoThe Xeon Phi was never meant to compete with GPUs directly. The first version was underwhelming and expensive but used in order cores. The next version is actually available to buy as some sort of limited release. It has out of order cores and 144 512 bit SIMD units (2 per core * 72 cores). The full box costs $5000 last time I checked.
