I wonder if the x86 dominance has declined slightly since 2015 - I know the #1 supercomputer is currently a POWER machine, and there have been some Chinese supercomputers that use their own manycore cpus with what I think is a MIPS-inspired ISA
- einpoklum 7y agoIt has begun to, in favor of AMD64 - with the Epyc processors which appeared in mid-2017: https://en.wikipedia.org/wiki/Epyc https://en.wikipedia.org/wiki/Epyc they've been generally competitive (probably much more so when you factor price in). Now, with Rome having come out, their market share is supposedly increasing quite rapidly, since apparently it trounces Intel's Xeon offerings.
- delish 7y agoGP said "x86 dominance" not Intel x86 dominance, for what it's worth. AMD64 is x86-64.
- jart 7y agoIt hasn't declined any more than pepsi and coca cola have declined, and there's no reason to believe it ever will. MIPS is gone. Power architecture being open sourced likely means IBM no longer has a business interest in it. This is what business folks call shakeout. It's what intellectuals would call the "end of history" for the microprocessor, similar to the fall the USSR. Big money research has moved on to quantum processors. Speaking as someone who's an avid reader of open source codebases, I kind of wish more of my colleagues would accept this, because it really stymies progress in open source that folks continue supporting huge amounts of code that today are mostly only used by folks doing things like emulating Sega Saturn on an FPGA for fun.
