Dave Ditzel (mentioned in the article) is still involved with RISC architectures. His current company Esperanto is shipping a 1088 core RISC-V processor. https

  To be clear, I understand that the chip is built from 4 general-purpose OOO RISC-V cores, one service (?) processor and the rest of them (1088) are intended for GPU-like compute. Then they build the compute by using Ice Lake Xeon to drive such 8x SoCs, where each of those SoCs are hosted on their own dedicated PCIe 4.0 slot. And then they upscale the whole thing to a dual-socket system which then translates to 17408 vector/tensor cores and 80 GP cores or ~17.5K cores in total. Pretty exciting.
