SiFive U8 Announced- RISC V designs on Steroids
RISC-V is the new buzzword that is taking over the tech world by storm and has prompted behemoths like IBM to open up its Power ISA. RISC V is an a CPU design that has its ISA open to everyone at large. However, its public availability for general usage is still rare. The ones which are available has abysmal performance in front of comparable ARM based development boards (eg. Raspberry Pi). One such manufacturer is Sifive who has announced its latest RISC V based CPU called SiFive U8 Series.
The series will have two CPUs, first high performance one being SiFive U84 while the Sifive U87 will cater to vector processing.
But What about the performance?
As per the manufacturer’s claim, the Sifive U84 offers 3.1X performance gains compared to previous core U74.
The 3.1X performance comes out from 2.3X increase in IPC. The remaining performance gains come from frequency gains. when compared to U54 manufactured at 28nm process, the U84 at 7nm manufacturing process gains 7.2X performance. The performance is comparable to that of ARM A72 core.
Summary of U84
Cores: from single core to 4 cores
Cache: 0 to 2MB
Fabrication: 7nm
Clock Speed: Upto 2.6GHz

What is RISC V?
RISC V is an open source Hardware Instruction set and thus can be used by anyone without paying any royalty. RISC V is the latest iteration which is based on the reduced instruction set. This is now being used by tech behemoths to countries who want their own Super CPU.
