SiFive’s brand-new P550 is one of the world’s fastest RISC-V CPUs

Today, RISC-V CPU design company SiFive launched a new processor family with two core designs: P270 (a Linux-capable CPU with full support for RISC-V's vector extension 1.0 release candidate) and P550 (the highest-performing RISC-V CPU to date).

There's quite a bit to unpack here today. Not only did SiFive announce these two new core designs, it also partnered with Intel. Intel will be the main development partner on the P550 core on Intel's 7nm process, and most likely, Intel will also build its own SoCs using these P550 cores. In other words, there's a lot of IP sharing going on here. This is a big step for both RISV-V and SiFive, and bodes well for the open source ISA as a whole.
