Help with AMD Thoroughbred-B vs. Barton

[bladestorm]

Well i'm pissed, I ordered a Motherboard/CPU combo online, got it today and installed it only to find the CPU is a Thoroughbred-B and not the Barton I was expecting. Does anyone here with experience you what I can do? The site I ordered it off of never stated what Core it was other than it is 333FSB. Being sort of new to Atholon XP's I thought that meant it was a Barton. Since the site fails to explain the exact specs of the CPU's they sell do you think they would accept an exchange if I call them on it? Also, is there a big performance increase from 256k L2 cache to 512k?


Thanks

The difference with the extra cache is basicly the difference between model ratings of similarly clocked AMD CPUs.

Notice only a few of them are BARTON cores.
2500/2800/3000/3200

For media/pro-intel applications bartons actually arn't as good as the thoroughbreds. But normal/games/buisness/server/workstation applications love Cache.
