CPU Cache

[holywars]

Can anyone help me with in a little debate I'm having with a few co-workers.

Does every CPU have cache? As far as I know all do (mainstream AMD's and Intel's) except for the early first Celerons. I was wondering about chips made by other comapnies (Sun, IBM etc)

Any help would be greatly appreciated!!

Even the early Celeron processors had cche, they just didnt have any L2 cache. They still had 32KB L1 cache.
All modern microprocessors be it X86 or otherwise have some form of on-die cache.

There have been processors made in the past that have had no cache at all though.

The Cray MTA architecture -- a super computing architecture from Cray uses no data cache (it does use instruction caches).
