Barton vs. T-bred, what is the difference?

[xts3]

Topic is pretty self-explanatory, what is the difference between the two chips? o/c wise and internally?

The Tbred has 256K of Level 2 Cache. The Barton ha 512K of level 2 Cache. The barton core is physically a little longer in size. The barton performs about 200mhz faster then an equally clocked tbred. thats why the athlon xp 2600 tbred is 2.08ghz and the athlon xp 2800 barton is 2.08ghz.

Some Batons (2500+) Are good overclockers. Some t-breds are (1700+) , if you get the right revision. I'd go for a 2500+ though.

While some report air-cooled 2.5GHz overclocks on XP2500+ Bartons, the best stable overclock I could get was 210 X11 or 215 X 10.5.

I replaced that 2500+ with a DLT3C XP1700+ that was game-stable at 222 X 11, which was the sweet spot for my system memory (2,2,2,7 @ 222MHz). Any theoretical advantage of the larger Barton cache is blown away by a significant overclock with a Tbred.

DLT3C XP1700s seem to be gone - but ExcaliberPC has DLT3C XP1800s for $65. If I were buying a CPU today, I'd grab one of those DLT3C XP1800s from Excaliber before they're gone.

If you're NOT going to overclock, get the Barton.

Hope this helps!

For the architectural differences I suggest you read the AT review of the Barton core....

Linkified for the lazy.
