Intel Mendocino Celerons

Intel Mendocino Celerons
by Charles Gamet

On August 24th, 1998, along with the Pentium II 450, Intel introduced the new Celeron 300A and 333MHz based on the new Mendocino .025 micron core, these new Celerons (Celerys ) offer a vast performance improvement over the original Celerons, and still maintain a very affordable cost.

The main difference between the new Mendocino Celerons and the original Covington Celerons is the addition of a fully-integrated L2 cache. This L2 cache greatly helps the business performance of the Celeron, and brings the Celerons performance right up to that of the Pentium II in all areas (well, almost anyway). :-)

The Celeron 333 and 300A MHz include 128K of fully integrated L2 cache. The original Celeron processor core for the 300 and 266 MHz parts had 7.5M transistors, the core for the new 333 and 300A parts however, contains 19M transistors due to the addition of the integrated L2 cache 128K.

Although the Mendocino only has a quarter of the cache of the Pentium II, it still offers very competitive performance. This is because the cache on the new Celerons is running at twice the speed it is on the Pentium II (the cache on a Pentium II is run at half the core speed).

The Celeron is an excellent overclocker - more so than even the Pentium II. Most people (myself included) have been able to take the 300a Costa Rica (Costa Rica and Malaysa both have 300a fabs running) up to 450MHz. My system:

Abit BH6 Jumperless Mobo with Softmenu
300a Costa Rica (4.5x100)@ 2.10v = 450mhz
258 sdram
Canopus Pure3D II
Win95

At this writing, I have had zero stability issues after 2 solid weeks of testing getting 50FPS Quake and running AutoCad LT at max res. I'm still fairly new to all this but I'm totally convinced this is the best and least expensive upgrade I've ever made. I got most of my info from PCBUILD (naturally) and Usenet newsgroup alt.comp.hardware.overclocking

If anyone else is doing this..please share some stories,I've heard some 333's are hitting 500+ mhz but experiencing some stability problems, I think it's been a heat issue, reports are it will soon be solved. Whatever happens, the OverClocking world is enjoying it's best days!
