IBM Power PC 1GHz chip only runs properly at 933MHz

But you can bet it will feed many "PPC sucks!" rants from the x86 crowd.

Probably, just point them to the errata pages for x86 chips.
Or tell them about the 3.6GHz P4, thermal throttling (clockspeed reduction) kicks in when it gets to hot, so much in fact that an older 3.4GHz will run faster.  It'll only run at full speed with water cooling!

You can also tell them about the recent Opteron bug (don't remember what exactly though).

So, nothing terribly exciting or unique.

What is surprising is the low number of bugs - only 8!

Early Intel Pentium III @1.13Ghz flaws only effects LinuxX86 (an example) but they run reasonably fine with Windows. Intel could have told those Linux users to do a code substitute trick, but the LinuxX86 markets demands product replacement and they got it.

No, that's how the bug was discovered, at that time Linux was an inperceptable part of the market.  However according to an on-line news site the kernel would not compile.  To Intel who had had a previous perfect record (apart from the P5 bug) this was unacceptable, they recalled the CPU.  It was only later re-introduced.

I expect IBM will have to pay out for this as well but you just won't hear about it as it's primarily in the embedded world.

and VIA’s C3(from Cyrix M3 core) is based from Cyrix

C3 is a Centaur processor, completely different from the Cyrix stuff which seems to have been pretty much abandoned years ago.

Cyrix were the last "true" CISC x86 CPUs.

All the VIA CPUs now are done by the group which used to be Centaur, they're still fairly autonomous today.

VIA's early Cyrix III (Joshua, Jedi, Gobi) was based on native x86 Cayenne core. In was later dropped in 2000 in favor of Centaur's WinChip/C5/Samuel. After employing Samuel core, VIA was still using Cyrix III label but this was shorten to just 'C3'. The C3 that I’m referring to is the x86 Cayenne core.

I see, so they have 2 completely different CPUs with the same name, and people think the IT industry can be confusing...


I'm referring to the C3 "Ezra", 12 stage, single issue, in-order.
