in the past as a relatively cheap x86 CPU. ($9.62 per unit)
However, it's a 400MHz 486 with some backports (1st generation Pentium, no MMX even) and broken LOCK prefix so that software specifically needed to be recompiled for it.
And at 2.2 W too, it never ended up succeeding anywhere, with no successor.
- toast0 6y agoI was pretty sure (without citations) the quark is a die shrunk pre-mmx pentium (but post division table bug), are you sure it's a 486? The right era pentium had the same LOCK prefix issue (we used to call it the F00F bug) Edit: Thanks for link; I must have anchored on the instruction set and ignored that it was using the 486 pipeline.

- tedunangst 6y agoThe fact it's got the f00f bug certainly made it sound like a dusted off pentium core.
- jandrese 6y agoYeah, but the PC104 boards that those got stuck on were still $250 each.
