SiFive just introduced new RISC-V CPU cores, named the U84 and the U87.
The U84 has 3.1x more performance at 7nm than the previous 16nm U74 core, this is a combination of 2.3x IPC and 1.4x clock frequency (I realise the math seems off, but it's their press release).
The U84 core area is about 0.28mm2 (7nm), with a quad core (with 2MB L2$) taking up a whopping 2.63mm2.
They claim competitive performance with the Cortex A72, though exact numbers are not forthcoming, only a footnote implying they were comparing against a Cortex A72 implemented at 16nm.
The U87 is similar to the above core (I presume for lack of further information and similarity of core number), but with vector processing too, further details on U87 will supposedly follow in a later press release.
(Sorry for the anaemic round of posts guys, I get a little over enthusiastic with a low attention span every so often.....)
