I read somewhere that the Cray 1 ran at 170Mips
I have 25 cent 32 bit micro-controllers that can do better than that.
The 100mhz ARM that controls an ordinary SD card is more powerful.
We live in amazing times :-)
Well, sort of. The Cray had quite a number of ports into memory to perform I/O. I saw a Cray that was front-ended with eight IBM 360s, each tasked with reading multiple tape and disk drives, card readers, and a fair number of 1403-N1 line printers concurrently. While the chips of today are amazingly fast, they do not interface with the world through so many peripherals. Also, the Cray had a floating point word size that today's microcomputers don't even come close to matching. The Cray was a floating point number cruncher, not a mere 32 or 64 bits in width. It consisted of a number of cores. The processor in an SD card doesn't even come close to those capabilities.
