Just two weeks after announcing his departure from Intel, Raja Koduri, former chief architect and head of the graphics business at Intel, made a new move by joining the Canadian AI startup Tensorrent as a board member. Coincidentally, the current CEO of Tenstorent is Jim Keller, who has had at least three overlapping career histories with Raja, namely Apple, AMD, and Intel. What's even more interesting is that Keller focuses on microprocessors, while Raja focuses on graphics.  Although joining the board of directors means not directly participating in research and development work yet, at least Raja will have his own voice in strategic decision-making. It is reported that Tenstorent was founded by Ljubisa Bajic, a former AMD engineer and Keller friend, in 2016. Currently, it mainly develops processor products based on the open source RISC-V architecture.  In the latest released performance comparison, its self-developed Ascalon CPU core is second only to the server side AMD Zen5 product that has not yet been released, leading NVIDIA Grace (ARM architecture) and Intel Xeon Sapphire Rapids. Today, RISC-V has become the third largest CPU architecture after x86 and ARM. Ni Guangnan, academician of the CAE Member, said recently that RISC-V is the most popular CPU architecture in China. David Patterson, founder of RISC-V and Turing Award winner, also believes that ARM and x86 are private instruction sets that require signing and authorization, as well as security concerns. RISC-V is free and open source, and is simpler and more user-friendly than x86/ARM. With more people participating in the development of instruction sets, there will be opportunities to achieve the best processors.
