That is probably generally true but if you have some serious compute workloads that you specialized for your server's CPU it could be hard to port between AMD and Intel as well. When people have customized the code for particular cache sizes, SIMD instruction sets, core counts, throttling schemes, ram throughput, and branch predictors and so on.
- agumonkey 8y agoIt's quite true, but what I've heard from FPGA users is that toolchain and conventions are aliens to each others, I think these are both two different kinds of hell. I don't know what would cost more to a company.
- ohyes 8y agoWhen you deliver an FPGA you’re normally also making your own hardware. That’s a big part of the FPGA porting cost, you have to redesign your boards. I don’t think the same is generally true in the x86 realm. Even if you’re specifically using some feature of the intel micro architecture it’s still essentially a code change rather than an full redesign.
