Athlon XP 2700 vs. 2800

[rmpuk]

Hi all

Can anyone tell me why a 2700 should benchmark faster than a 2800? MB is Asus A7N8X-E.

Sisoft tells me the 2700 run at 2.17GHz and has a 256k L1 cache, whilst the 2800 gets 2.09GHz and has a 512k cache.

Any ideas?

Thanks.

It's probably because the 2700 is a Thoroughbred, and the 2800 is a Barton.
A 2800 Thoroughbred runs at 2.25 GHz.

Yep, you are comparing two different models. The Barton's extra L2 cache normally compensates for it's slower clock speed.

For example, a Barton 2800+ usually performs 3-5% faster than a Thoroughbred 2800+

I have an Athlon XP 2700+ Thoroughbred CPU and I love it, it performs well for me and it really depends on if what you are doing utilizes the cache a lot or not.

The 2700+ is 2.167GHz (Thoroughbred)
The 2800+ is 2.086GHz (Barton)

Not sure what the 2800+ can do overclock wise, but I know I have my 2700+ running at 2.41GHz without a hitch. (yes, it's unlocked from the factory)

If you need any other information regarding the Athlon XP's with respect to specifications, you can referecen the FAQ I wrote on the processor line.

When you start comparing with the new Sempron line, the numbering system becomes even more out-of-whack. For a socket A Sempron, you need to drop 300 PR points off the rating to get the equivalent Athlon XP model. So, XP 2000+ ~ Sempron 2300+.

The XP2.6+ has been a classic example of the differances that buyers have experienced with just one CPU.

Off the top of my head (so don't quote me on these figures)there has been 4 differant CPU's at XP2.6+

The original 266fsb Thoroughbred @ 2.108 256L2
then the 333fsb Thoroughbred @ 2.083 256L2
followed by the Barton 333fsb at 1.920 but 512L2
and the cutdown Barton(Thornton) 1.920 halved again @ 256L2
and back it seems to the Thorougbred 333 @ 2.083

But I reckon in years to come the Barton will become something of iconic symbol amongst CPU's
