Could you elaborate why AVX-512 is not important? I guess that you are referring to GPGPU programming is what everybody is doing right now instead of SIMD in the CPU.
- gigatexal 8y agoI could be talking out of my butt but it’s my understanding that AVX512 isn’t used in but few niche programs.
- oconnor663 8y agoIsn't that niche the same as the niche of programs that can realistically max out a modern desktop CPU? Video encoding, compression, and things like that?
- gigatexal 8y agoaccording to this only x265 uses AVX512: https://software.intel.com/en-us/articles/accelerating-x265-with-intel-advanced-vector-extensions-512-intel-avx-512 https://software.intel.com/en-us/articles/accelerating-x265-... But I wouldn't doubt that things like Video encoding / compression uses this. Again, I was not saying it's not valuable just saying that for my use case where I don't encode videos for a living or run a large Handbrake/Plex video farm / library the i9 cpu is not worth as much to me as the cheaper, cooler running Ryzen 2700.
- gigatexal 8y agoIt’s important yes but hard to implement I think and not widely used is what I was getting at. For me compiling and running VMs I’d take the Ryzen over this.
