Difference between P2 266 and Celeron 466?

[johnjk]

Is there a lot of difference in speed? TIA

 

[ElFenix]

short answer: yes.

longer answer: the p2 is running a 266 core with 512k 133 mhz cache. the celeron is an upgraded core, the deschutes, and is running at 466 with 128k of 466 mhz cache. not only does it get speed from the core simply running at 40% more mhz, but also the cache, though small, is running 3.5x faster.

ElFenix: almost exactly correct.. minus the part about the deschutes core.... only the celeron 266 and 300 with no cache used the deschutes core(well P2's from ~266/300(rare, SL2YK anyone?)333-450)

celerons from 300 and up used the medocino core... well minus the FCPGA which are of course coppermines🙂

ahh yeah... you'd prolly see a ~50% performance increase in CPU intensive tasks...

 

[ElFenix]

well, technically, the 266 and 300 used the covington core... but it was all just deschutes...

266 and 300 were Deschutes cores, but the non-cache Celerons were code named Covington. Mendocino refers to the core, rather than the code name for the Celeron. Essentially the Mendocino core is the same as the Deschutes core with 128KB of cache tacked on.

Alright, you guys are getting way to technical for me. 😀 thanks

johnjk,

The 466 will kick all over the 266.

466-higher speed(you knew that)
466-faster full-speed cache(awesome), tho smaller(no biggie)
466-easier to over-clock(higher potential)
466-lower micron, easier to cool to due to open-design

266-cache runs 1/2 speed(chuga chuga)
266-runs very HOT! (i watched a p2-300 melt once it was cool)
266-wearing armor plating, hard to cool unless you void your warrenty and break the casing.
266-1/2 speed cache affects the overclocking potential
266-was barely faster than the old 233 socket 7's Doh!

I tried to be as non-technical as possible, those guys made me dizzy... rofl...

Yea, I think a P-Pro 266 would be faster than a P-II 266 though I'm not sure. I do have a vague memory of an article somewhere saying that the P-Pro could outperform the early P-II's, but I may just have been dreaming. The Celeron will be a good deal faster.
