Powerpie, hope this helps, some tests I did with with Coppermine and Tually:

So, does anyone know if a 1.4GHz Tualatin Celeron will be a noticeable improvement over my current 850MHz Coppermine PIII? Both run on a 100 FSB and use PC100 SDRAM.

Unfortunately, I cannot comment for the enhancement of a Tualatin at 100 MHz FSB, however I did just upgrade from a dual Coppermine 850 MHz (100 MHz FSB) to a dual Tualatin 1400 MHz (133 MHZ FSB) as my everyday computer and found the speed of general web browsing and business applications to "feel" about 3x faster. Perhaps with a 100 MHz FSB, it will "feel" more like 2x faster.

Cool, thanks! I'm thinking a 1.4GHz Celeron might be about as fast as the 1125MHz PIII-E in your charts, or maybe even slightly faster? (I hope 😁).

I'm not expecting a massive improvement... I mainly bought the Powerleap + 1.4GHZ T Celeron to max out my 440BX system 😀.

Both are more than enough for games until 2000, both equally suck for games 2002+.

But that's not what i asked 😜

It's a question of what one gets for the hassle and price. Those adapters aren't exactly common, so for most people it should be not recommended to shell out the money for one just for a (very few in high resolutions) occasional more frames that won't radically change how a game runs. A Pentium III is simply not enough to play UE2 and similar games from that generation to their fullest with whatever video card. So even if you didn't like the answer, it holds true for the majority of people 😜

Or let me put the question like this: What games didn't run on your PIII/GF4 system to their fullest?

It's called the law of diminishing returns. For modern browsing and videos etc. both of those setups are so underpowered that even a slightly faster CPU will bring good improvements. The same can't be said for gaming, where GPU fillrates etc. perhaps count more, especially at the high resolutions and image quality settings one would probably want to run today. If the CPU is at a point where it won't inhibit overall game performance noticeably, that is.

I'll do a test with the Tually at FSB100 and we'll see:

At 1052MHz FSB100 the Tualatin 512K is slightly ahead of the Cumine 256K @ 1125/150.

I'd expect your Tualeron 256K @ 1400/100 to perform at least equal, and probably better than that.

That's great, at least i know it'll be better than my 850MHz PIII-E. It also means i've upgrade this old 440BX board to the max 😁. I have a few more GPUs, but i've not completely decided on which to use (It'll be using a 3.3v AGP 1.0 2x slot):

64MB Asus Geforce4 MX440 (passive, so it's silent!)
64MB Asus Geforce4 MX460
64MB Gainward Geforce4 Ti4200 (i thought it was 128MB, but it's not 😒)
128MB ATI Radeon 9500 Pro

I'll test them all out when i get the chance.

My Powerleap is running perfectly with a 1.4GHz Celeron 😀. The motherboard bios detects it as a 'Pentium Pro 1200MHz', but everything else detects it correctly. I also got myself a cheap Gainward FX5700 (not the slower LE, XT SE versions).

Congrats!, welcome to the 'Tualatin on BX' club, a combination that was never meant to be, but works like nothing else.

How much faster does it feel compared to your PIII-850?

Here! Here!

It's been running nicely and it's even better now i've installed the FX5700 😀... The fan on the Gainward FX5700 is a tad loud with it spinning so fast! But it's easy enough to replace.

It was noticeably quicker when it came to gaming using the same GF4 MX440 card, but now it's even better with a GF FX5700 installed 😁.

So for anyone interested, i can confirm the good old Intel SE440BX2 mobo is perfectly fine at running a Geforce FX5700 and a 1.4GHz Tualatin Celeron via a Powerleap iP3/T adapter... It's also fine with 768MB RAM (although i'm only using 512MB until i find a good low profile cooler for the Powerleap adapter).

I can now also confirm my SE440BX2 board is fine at running 768MB RAM without modifying a single thing with Windows 98se... No 512MB limit issues here 😀.

Nice to hear that, well done .
