So, for Ryzen processors where the CCX core split is 2+2 (1400/1500) or 3+3 (1600/2600) would you not be potentially overloading each CCX (regardless of SMT)? Otherwise, isn't a significant issue the CCX interconnect being hamstrung by being linked to memory speed and if you have fast memory (2933+) it's not such a burden? -- Alan. _______________________________________________ mesa-dev mailing list mesa-dev@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/mesa-dev
