Intel's x86 microprocessor architecture has dominated large swaths of computing for three decades.

June 5, 2008 (Computerworld) Thirty years ago, on June 8, 1978, Intel Corp. introduced its first 16-bit microprocessor, the 8086, with a splashy ad heralding "the dawn of a new era." Overblown? Sure, but also prophetic. While the 8086 was slow to take off, its underlying architecture -- later referred to as x86 -- would become one of technology's most impressive success stories.



"X86" refers to the set of machine language instructions that certain microprocessors from Intel and a few other companies execute. It essentially defines the vocabulary and usage rules for the chip. X86 processors -- from the 8086 through the 80186, 80286, 80386, 80486 and various Pentium models, right down to today's multicore chips and processors for mobile applications -- have over time incorporated a growing x86 instruction set, but each has offered backward compatibility with earlier members of the family.

Why no x64 :P

its getting old we need a new microprocessor architecture :)

wow . . . I hadn't realized just how old the standard was - I mean, I knew the 186 processors were x86, but hell . . . :twitch:

Commiserations to all the other CPU architectures of the time that didnt make it. Although some were INCREDIBLY successful in the 70's and 80's. RIP.

Zilog Z-80, Z-800, Z-8000
Motorola 68000 Family
MOS 6502
NEC V20 and V30

We do have new architecture. X64, Cell, Power etc..... Plus all the phone processors are a inbreed of multiple different architectures.

Then buy IA-64, it was intended to replace x86 in the first place anyway.

Oh, and you can afford an Itanium workstation (http://cgi.ebay.nl/Itanium-2-HP-ZX2000-1-5-6M-2Gb-734Gb-Windows-XP-64IA-EC_W0QQitemZ230260446001QQihZ013QQcategoryZ1484QQs sPageNameZWDVWQQrdZ1QQcmdZViewItem). Seems the title misses a comma though. Slightly retarded how it has a U160 controller as well.

Dan, is an itanium workstation running XP IA compatible with normal XP software? Or does IA require IA versions/builds of software, e.g. office, etc. Or is it able to execute x86 code natively?

Well, Itaniums can emulate x86. Not sure if that means XP-IA64 runs x86 software or even x86-64 or that you're required to run standard XP editions.
Performance wise Itanium 2 emulates at the speed of a Xeon at the same performance level, that was said during the Prestonia days, so compare it to a Northwood.

Woo!! x86 for life!

I like the 32 bit way better than the 64 bit OS anyway. More stuff is compatible :)
