I have another system to setup for BOINC'ing.

This is for a MSI K7N2 delta mobo

Should I do a 3100mhz Semperon for its intergrated bus/memory controller or a 3200 mhz Barton for its 512k L2

---

The Barton, being able to load the WHOLE process into L2 cache makes the process MUCH faster! I have 2 Celeron cpus that also have a low L2 cache and they are doing units in half the time of 512k size L2 cache machines.

i have a AMD XP 2000+ and a Sempron 2200+ and the XP edges it out slightly. other than that they are the exact same PC. (11,000+ secs compared to 12,000+)

Roughly Sempron=Athlon XP with a different name.

the Semperons have only 256 KB Cache and the Barton have 512 KB Cache...

Not all AthlonXPs were Barton cores though.

Why does AMD bench mark the sempron to the celeron and not the XP?

You are probably best to get the AthlonXP 3200+ as all the Sempron 3100+ I've seen are socket 754's and therefore wouldn't even fit in your motherboard. I do have I Sempron 3100+ and for a CPU running at only 1.8ghz it's actually really fast, especially considering the price. It's almost half the cost of a XP3200+. It does a Seti workunit in under 3 hours right now but I'm using slow memory I just had laying around DDR333, probably would be quite a bit quicker with good DDR400. Also Semprons are rated against the Celeron D's and thus the 'speed rating' is inflated compared to the XP's, you really need to look at the actual clock speed to compare the two.

Becasue the AthlonXP/Sempron is now their budget CPU, the Duron is being (has been?) discontinued.

Great discussion........I have learned a few things about these processors the past few days.

Socket 754 Sempron 3100+ is different from the rest of the Sempron herd.
It is basically a neutered A64.

The rest of the Semprons are Socket A and should run fine in Socket A mobo's....a bios flash might be required.

Because of the 512K L2 cache, the Barton out-performs on a average about 8-10% better than a t-bred or sempron at the same clock speed and same fsb speed.

Dont forget, mobile Bartons are FSB/Multiplier both are UNLOCKED!
They also run at 1.45 volts instead of 1.65 for the desktop bartons.
I have seen stats of these running stable out to 3500 mhz.

Local pc shop is offering a Mobile Barton 2500 for $105.
