OK, just for interest -

Is there much of a improvement over a PII 400MHZ CPU, compared to a PIII 450MHZ CPU. (apart from the 50MHZ difference).

If you use encoding/rendering apps. that have SSE support, then you'll get some improvement.

In other apps, the improvement is not noticable.

P3 450 MHz = PII-400 + extra 50 MHz + SSE

OK, one other question -

Much of a difference in performance between a Celeron 400 CPU and a PII 400 CPU?

Thank's,

Celeron 400 is nearly as fast as the PII 400, because even with it's slower bus speed and 1/4 the cache, the cache runs at full die speed instead of 1/2 die speed.

In fact a Celeron 300A at 450MHz (via overclocking) is faster than a PIII 450.

Ah, the good old days. :smile:

I had a couple 300a's running 464MHz on retail heatsink/fan. And at $100 or so compared to almost $1000 for the PII450 when it was king. That's when overclocking made the most difference. Same performance for 1/10th the price. And a 266 running 412MHz before that. I have fond memories of those BX chipsets and those early celerons.

ABIT IS7, P4 2.6C, 512MB Corsair TwinX PC3200LL, Radeon 9800 Pro, Santa Cruz, TruePower 430watt

And not to forget, with the full speed cache, a simple increase in bus speed to par with the PIII 450 put the Celeron as the performance LEADER at 1/10 the cost!

This was oc history! This was the first time I found out about it, and a lot of todays enthusiasts were prolly bred on the thing...

A long long time ago, but I can still remember, how that music used to make me smile... <A HREF="http://www.nexus.hu/zonix/DIGGER.MID" target="_new"><b><font color=blue>Digger rulz</font color=blue></b></A>

I think it was this simple yet powerful overclock that made TGH so well known. Simply put electrical tape or whatever over pin b21 or b29 (I forget which) use a bx board with pc100 sdram and whallah 50% overclock.. best trick I ever got from TGH. I still got a friend using that setup under win98.

If I glanced at a spilt box of tooth picks on the floor, could I tell you how many are in the pile. Not a chance, But then again I don't have to buy my underware at Kmart.
