Is the Vortex86EX the only remaining i486 processor in production?
- actionfromafar 4y agoI think it has 586 instructions, but speed is like a 486.
- speed_spread 4y agoDoes it run like a 300Mhz 486 would or is the IPC so bad that the clock boost is all wasted compensating for silicon design limitations?
- timschmidt 4y agoIntel Quark (https://en.wikipedia.org/wiki/Intel_Quark https://en.wikipedia.org/wiki/Intel_Quark) has been updated with 586 instructions, but is still built around the 486's 5 stage pipeline.
- Teknoman117 4y agoI thought Quark was out of production at this point (last shipment was supposedly July 2022). And yeah, I remember all the segfault fun trying to get a generic Linux distro running on it at a hackathon back in 2014.
- timschmidt 4y agoIntel's management engine is built on their Quark architecture now, and runs Minix 3. Doesn't seem like Intel is likely to change this any time soon, as the previous architecture they used was a real odd duck and Quark seems like a much better fit. So it's likely to ship in every Intel machine for the foreseeable future.
- soneil 4y agoI had the same issue - iirc it's a 486 with some Pentium extensions. It has enough of the 586 set to fool you into thinking it is one, but not enough to fool glibc. So you need to have glibc specifically built for i486 otherwise life gets dark.
