I would just like to add in that RISC-V is still a lot of talk because there are still some important standards that really need closer attention before we start mass-producing server CPUs. Specifically, the Platform-Level Interrupt Controller[1] and the Vector Instructions[2]. The former is super-important because we now know interrupts/traps can be used in Spectre/Meltdown style attacks, especially if your chip has something like a DSP/iGPU, which can be used in covert side channel attacks. The latter will be important for the same reason that SSE/AVX is important today. Just my opinion, but SiFive has been a huge driving force in even giving RISC-V a shot at breaking into server space. Most other companies (Google, Nvidia, Western Digital) have invested in RISC-V with the apparent intent of focusing on building microcontrollers/embedded processors. AFAIK, there's only one player who is investing in building RISC-V server-class CPUs and that's SiFive. Please correct me if I'm mistaken! I've been following RISC-V pretty closely for the last year or so and there's quite a lot to catch up on. 1 = https://github.com/riscv/riscv-v-spec https://github.com/riscv/riscv-v-spec 2 = https://github.com/riscv/riscv-plic-spec https://github.com/riscv/riscv-plic-spec
