As requested:

Ambers: 70ppd/GHz/core
Gromacs: 60ppd/GHz/core
DGromacs: 155ppd/GHz/core
GBGromacs: 75ppd/GHz/core
Tinkers: 85ppd/GHz/core
Big Gromacs (600 pointers) 125ppd/GHz/core (requires bigpackets=yes)
Big Gromacs (364 pointers) 175ppd/GHz/core (requires -advmethods and bigpackets)

The unit of measure ppd/GHz is used because performance within a family of processors scales linearly. Saves having to figure out how many GHz a 3800+ or Intel 650 is since AMD and Intel quit using the GHz to identify the cpu.

Single core A64s with 512 MB caches produce about 185ppd/GHz on p1481 (364 points). Single core A64s with 1 MB caches produce around 210 ppd/GHz on p1481.

You come up up with some great material.

Yet another reason for a ChasR sticky.
Awesome info man!

I've got an Opty 165 Dual core o/c'd to 2.5, and just barely the estimated PPD with multiple processors folding for me (2 HT P4's and my dual core opty). Im only pulling in anywhere from 200-400 if im lucky.

Expected Athlon XP production:

Ambers: 66ppd/GHz
Gromacs: 53ppd/GHz
GBGromacs: 72ppd/GHz
DGromacs: 82ppd/GHz
Tinkers: 85ppd/GHz
Big Gromacs (600 pointers): 112ppd/GHz
Big Gromacs (364 pointers): 123ppd/GHz

These numbers come from my XP-M (Barton) fleet, all similar to sig rig #3.

Older XPs and XPs on slower FSB may not produce as well on the big Gromacs, particularly p1481, due to memory bandwidth bottlenecking.

Do you have any data on Sempron folding?

It should be close to the XP Barton. There isn't a whole lot of difference between the Bartons and the A64s except on the high bandwidth simulations like p1481. The same will hold true for the Semprons.
