Talk:Intel 80486DX4
From Wikipedia, the free encyclopedia
I read somewhere that Intel also produced a rare DX4-120MHz processor. Can anyone confirm?
Very unlikely, Crusade. Intel were firmly wedded to their 33MHz bus. They had burned their fingers with the notoriously troublesome 486DX-50 prior to this, and were determined to do nothing too sexy in 486 space by this time, lest they take the gloss of their brand-new (and very expensive) Pentium-66 - which was only marginally faster than a 486DX/4-100. A DX/4-120 would have been a very silly move for Intel. AMD made one, of course, as did Cyrix, but that was pretty much a paper product, as they had their 5x86 happening by that time. Only AMD made 486DX/4-120s in commercial quantities - largely because Intel and Cyrix both had new, bigger chips ready and AMD's K5 was running very late till the K5 arived. It helped keep them afloat. Tannin
- I just read that a handful of the very last Intel 486s produced were marked as 120. Maybe for OEMs to stave off an order from AMD? Rare oddball one-off parts that nobody has heard of sometimes exist, like the AMD DX4-90. I know what you're saying about Intel & Pentiums.
Yes! I can confirm such a thing existed - my first PC had a 486DX 120Mhz CPU! I bought it here in the UK (second hand, at a computer fair) if that is of any help. Actually, re-reading through the posts above, I can't be 100% certain it wasn't an AMD or Cyrix... but I'm fairly sure it was an Intel... (And for nostalgia's sake.... it had 8mb of RAM, and a 500mb hard drive) pomegranate 21:44, Mar 15, 2005 (UTC)
I've had a pretty good look around and all I can find reference to is the AMD 486DX4/120s. I don't think Intel produced any publicly available 120s. There might have been a paper idea for it, but as previously mentioned they already had bigger and better fish to fry. Pomegranite: Don't forget that AMDs were called 486DX4s whilst Intels were 80486DX4s. Easy to confuse them! Dancraggs 10:43, 22 March 2006 (UTC)
