The Duron 1400 should be Applebread core, not compatible AFAIK.

The Duron 1300 is a Morgan core, and should work in any KT133 based board providing that the BIOS has the microcode to read it properly. I've had both Palomino and Morgan based builds, and I never noticed any lack of performance without having SSE and hardware prefetch.

Hi,
I am testing a late KT133 config and was thinking one of these cpu. I already have the Duron that seems ok with Linux but definetely the cache is not great. What do you think about the lack of SSE and hardware prefetch of the Palomino vs the Morgan core?
Thank

The KT133 doesn't support 133MHz FSB, got to have the KT133A for that.

This rasies an interesting question, if the KT133 supports the Morgan core would it also support Athlon XP M-1600 a 1.6 @ 100mhz FSB cpu?

Aaaaah the pain of VIA socket A.... everytime you had to deal with boards that you thought could do something, but then you needed an ''A''. 😵

KT133A, KT266A, KT333 (early ones still couldn't do 166fsb, so later ones were like an ''A''),KT400A

Not much wrong with the chipsets but it would have been nice if they made the right versions straight away. (Or used different names. Why kt133 if it cannot do 133fsb etc.)

Anyway, this is between athlon1400 and duron 1300? Athlon 1400 Thunderbird does not support SSE, Palomino one does. 1300 Morgan does also support SSE.
Thunderbird CAN be 100fsb, Palomino is 133fsb. Clock for clock a Palomino is a little faster than Thunderbird.

Maybe you can try and run a Barton at a low speed (fsb), it has 512kb cache.

Agreed, and the original KT400 didn't even support 400MHz FSB or 400MHz DDR SDRAM. 😵

Thank for your answers. I found today an Athlon 1333/133 for my KT133A (sorry I forgot) asus board and I can say the differences with this until I'll receive the 1400 version soon.
Using linux, I would say that the 256Kb cache make a big difference from the Morgan core of the Duron 1300. Maybe the 133 FSB/133 Ram 1:1 is a the main point here but I would not say I feel the lack of the SSE right now.

The 1400/133 is kind of cool as the fastest Thunderbird but it has a ridiculous 72W TDP and will need a beast of a PSU.
For stability a low-voltage Barton is a much better bet.

Eh? 400MHz FSB, no, but pretty sure PC3200 DDR was (maybe not on some rebadge Tsing Tech crap).

VIA wasn't flashy and don't go near it with a SB Live, but I've always found it to be a reliable core logic vendor.

Yeah, with the 1333 version I already have sort of the same power wattage at the plug that I had with the Barton 3200. 😵

Would be interesting how much each of technology (SSE / data prefech) result in better performace for the AMD cpu's.

My research on 'tomshardware'-benchmarks has shown that, for example, the speed difference (due to data prefech unit) between PIII coppermine and PIII tualatin is around (~) 3% to 6% at equal clock & FSB speed.

I like to use KT600 boards with these older Athlon and Duron processors. Runs very well and makes a great DOS / Windows 98 hybrid gaming machine. To me it seems that around 1 GHz is sort of a sweet spot between performance and power draw.

But for older type games wouldn't KT333 make more sense it supports AGP 2/4

It's a 1 Ghz machine. I don't see old games as the target here.

Yeah I built a KT600 system but I wanted to use also an older vga. Now running a R100 Radeon card. 😀

After some more real usage tests with browsers, I would say the Athlon 1333 feels much better that the Duron 1300. I don't think the SSE is enough to compete with the cache and faster ram.

Looks like I did not receive that memo.

athlon is the clear winner considering things like:

(looks like l2 cache!)

Duron only beat the Athlon at this

(looks like SSE!)
and not by much.

Prefetch should help keep the pipeline stuffed, but SSE 1 was more about software which didn't have an optimized x87 or MMX code path.
