FYI, Jan 5 saw the launch of the 400MHz Celeron both in the Slot One (SEPP)
and PPGA Pin Grid Array Versions (sorta like socket 7 but not). Although
the celeron has its 'own' chipset - the EX, all the Celerons that we have
built have used a BX motherboard. All decent BX motherboards support the
Celeron in Slot One versions.
The PPGA motherboard uses a ZX chipset if I remember rightly. How this
compares to the BX as far as performance is not aparent at this time.
I have several friends who are using Slot One Celerons for heavy gaming
(Quake, Unreal etc) and I have to say the 333 I saw (actually built) had FPS
rates comparable with a P2 +/- a few %. The 300s and 333s can be
overclocked simply by upping the bus speed and it is VERY common to see 300s
running at 450. The 333 requires a little more cooling to run at 500.
I would steer clear of the old cacheless 266. I think It was the first
Intel CPU EVER to have an IComp2.0 rating LOWER than its clock speed and I
read several web reviews comparing it to a lowly 200 P55C.
If anyone would like us to build a GIMPS cruncher, let me know.
