AMD is segmenting to Gaming (RDNA) and Compute (CDNA) - CDNA is essentially a continuation of Vega, which was a beast for compute.

- dragontamer 6y agoRDNA's ISA is impressive. Load/store asymmetry, Subvector execution, 1024 vGPRs (!!!!), unlimited sGPRs (not quite, but no longer shared at least), etc. etc. Based on the ISA alone, I'd prefer compute-applications to move to RDNA frankly. Its clearly a better designed architecture. ------------ I can't find any public information on CDNA. I've even emailed ORNL for information, but they responded back saying that NDAs prevent them from saying anything. Whether CDNA is based on NAVI or Vega will be a big question as Frontier launches next year. I hope its Navi based, I really do, because its just better. But I'd "understand" if ROCm can't be ported easily to Wave32 or other issues (RDNA is a huge architectural change).
