advantage? this just allows for dual cpu setup, no?

You can unlock the multipliers that way.

Has anyone actually seen a Pentium 3 1400 non-S chip?
All of the ones I ever read or heard about, were the 512KB server variants.

Seems like any non-S P3 clocked above 1.2 ghz are rare, the only P3 non-S i have is the 1.2 Ghz model. Intel made multiple Tualatin P3s and Celerons during their lifetime

P3 (Tualatin 256/non-S):
1.0
1.13
1.2
1.33
1.4

P3-S:
1.0-S
1.13-S
1.26-S
1.4-S

Celeron (Tualatin 256):
1.0A
1.1A
1.2
1.3
1.4
1.5 (extremely rare)

Also there are a few references about a 1.53 GHz Pentium III-S mainly from HP and few other websites.

I've found that Athlon and Athlon 64 systems on VIA chipsets often have some kind of performance issue that dramatically reduces GUI performance. I used Tom2D to compare VIA K8T800 and KT333 to nForce2 and the NV chipset blew the others away with the same video cards. It's most obvious when a full screen fill happens, like a minimized window going back to full screen. I think it is apparent with web browsing too. That might affect video as well.

3DNow is apparently at least somewhat useful for video decoding. People wrote 3DNow iDCT functions, for example. But yeah SSE is definitely useful. I had a P3 Katmai downclocked to 300MHz and it could still play DVDs in software without a problem.

There was a VIA PCi Latency Patch for some speed issues.

But I own a PIII-S1400 and next week I get a AMD Gedode NX 1750 (also 1400 mhz). This is also a nice benchmark, also because the P-III has 32.2 Watt TDP and the AMD has 25W.

From what I see on this CPU, and reference images, the L1 cache lines are already connected 😀 Can it work with 11.5x (1.53GHz)?

Nice roundup from 2003.P3-S loves Quake 3.

Yeah, I've seen exactly what you're describing with VIA chipsetted boards. It's not limited to AMD systems. I've had VIA based PIII, P4, and even Core 2 boards with very slow 2D performance. Nothing more frustrating than watching a good CPU's performance go down the toilet because of a shit chipset. At least with faster systems like K8 or Core 2, you can use Windows 7 which does a really good job of hiding the slow 2D.

It's a minor miracle that my current PIII board, based on the Apollo Pro 266T, doesn't seem affected by the slow 2D bug, even with a 6800GT. With my previous PIII board (VIA 694T) I had to use ATI graphics because 2D was so slow with nVidia GPUs.
