A: No. Fujitsu and RIKEN are developing post-K, aiming for starting operation around 2021. This 2.2GHz CPU has 48 cores, a combined 3.38 TFLOPS, and 32 GB HBM2 ram. Because it’s just a general-purpose CPU when it comes to efficiency per watt it even surpasses AMD and Nvidia GPUs. The Fujitsu A64FX, the only ARM-based processor designed for HPC projects and supercomputers from scratch, will soon be deployed to Sandia National Laboratories. Intel and AMD practically dominate the processor chip market in desktop CPU space, server-grade CPUs, HPC (high-performance computing) ventures, and much more. However, Japanese tech giant Fujitsu with its latest release (Fujitsu A64FX) appears to threaten that dominance. Read our special supplement celebrating 60 years of Electronics Weekly and looking ahead to the future of the industry. stream It has 48 calculation cores and two or four assistant cores, and has a theoretical peak performance of 3.3792 teraflops in double precision floating point calculations. A benchmark used as an indicator of memory access performance. As of June 2020, the Fugaku is the fastest supercomputer in the world by TOP500 rankings. As to SPARC -> ARM transition, the post-K project has to show its performance and reliability, both in terms of hardware and software first. The successor of the Fujitsu A64FX, the Fugaku, is projected to be 100 times more strong and hit a whopping 400 petaflops, reportedly. It's very well known. Thanks Ian!
