  Hot Chips 2020 Live Blog: AMD Ryzen 4000 APU (Noon PT)

  Q: Melt, Spectre?
  A: Melt doesn't impact AMD. Zen 2 has hardware mitigations for Spec v2/v4. Added Guest mode execution, virtualization security, IOMMU throughput, TME

  Q: 8 cores in this size, trade offs?
  A: We wanted to provide the 8 core perf, and as we analyzed with 7nm that if we took care we could enable 8 cores. Lots of content creation takes advantage of 8 cores. These come in handy with high perf applications. On the GPU, we were also careful in perf/watt and perf/mm2 that we can drive. We figured out in 7nm we could get higher frequency, so we balanced resources and that's why we went for 8 CUs. Vega with mem bandwidth gives better UX in 15W
