Barton is coming!

MPs: February 4th.
(MP2600)

XP: Feb 7
(XP2500+, XP2700+ and XP3000+)

Will it be worth the price and the wait though? O/Cers mentioned a 6% boost when doubling cache size for the P3 from 256 to 512. Assuming that is about right (we'll call it 10% for erring on the side of fanboyism), when what are we looking at? The TBredAs (you can get a 1700+ for around $60 I think) mostly do 2000MHz with o/cing. That is somewhere in the 2400+/2500+ range already. The Barton will be about 4x as expensive for (presumably) roughly the same performance. Remember that AMD is boosting the PR to account for extra cache and 166fsb, while my Epox 8k3a does not in its PR calculation.

For my money, the lowest speed not bin-sorted TBredB is the AMD CPU to have for the next 6 months or so. Check o/cers for details on "A vs J" TBred Bs.

I just hope that there won't be another rev A and rev B fiasco, but that's probably just wishful...

I attempted to calculate, from pics posted everywhere, the size of the die:

Where TBredB was 11.33 by 7.47, I estimate the Barton core to be about 13 mm, with the same height. (using the various reference points around the CPU). The picture is skewed, so a pixel by pixel comparison wouldn't be accurate.

The wattage is estimated at:
68.3 for the 2500+, same (?) for 2800+, 74.3 for the 3000+ and unknown for a 3200+.

Here's a comparison pic, the source of my "guesstimate" (along with AMD specs).

Here's another pic:

A pixel by pixel measurement might work, let's see...

TBredB: 108 to 159 = 51 pixels wide
Barton: 335 to 398 = 63 pixels wide

so Barton is 23.5% wider, so it should be... 14.00 mm wide!

The specs are in: Athlon XP model 10 (a 98 page PDF, by AMD).

It's 7.42 by 13.61.
