Posted by Arris -> What do you think about the new AMD Clawhammer
Found a link over at
www.amdzone.com to a post on realworldtech.com forums estimating what sort of performance increase we can expect with the release of the hammer and its related technologies.

From
www.realworldtech.com forums :
Reference point:
- K7 XP 2000+
- at or near end of performance scaling in 0.18 um bulk CMOS
- 1667 MHz, ~700 SPECint_base2k, ~600 SPECfp_base2k
Hammer top bin clock rate (early/mature):
- 5%/5% bump from 12 stage pipeline (extra stages mostly for IPC
gain and for handling extra complexity of x86-64)
- 20%/25% gain from 0.13 um (wire limitation, limited Leff reduction
from late model 0.18 um K7s vs use of 0.09 um FET techniques)
- 10%/15% gain from SOI
Total +35% early, +45% mature
So "IPC" improvements relative to XP (with x86-64 recompilation):
Clawhammer:
int: 20% MC + 5% FE + 5% x86-64 = 30%
FP: 5% MC + 0% FE + 10% x86-64 = 15%
Sledgehammer:
int: 25% MC + 5% FE + 5% x86-64 = 35%
FP: 40% MC + 0% FE + 10% x86-64 = 50%

Just thought that this would give us something to nibble at until any real benchmarks are out
