OMG - G5 2.5 GHz 970MP: SPECfp_rate: 42.8

I'm no SPEC expert, but that seems really, really good:

SPEC2000 rate (peak) 2-way
Prozessor Takt SPECint_rate 2000 SPECfp_rate 2000
PPC970MP 2,5 GHz 32,3(est) 42,8(est)
Power5+ 1,9 GHz 39,6 67,6
Pentium D 3,2 GHz 32,6 32,5
Xeon Paxville 2,8 GHz 33,2 29,9
Opteron 180 2,4 GHz 37,5 34,4

Yup purty durn good Floating Point performance on those chips, however in Integer based appz, Opteron pwns.

Why "est" ?

Indeed.

2,5 GHz 970MP:
1428 SPECint2000
2076 SPECfp2000

Presumably because IBM hasn't submitted the results to SPEC.org yet. However, even if the score dropped by say 5% on shipping hardware (not tweaked lab stuff), that'd still be damn impressive.

Hmmm... I've seen an Opteron 180/280/880 perform the same in SPECfp2000. What gives?

Nah. Nothing wrong with Macs. It's the "Mac-cult" that can be a bit stupid though... Ohh, and the general lack of hardware knowledge in the community. Atleast that's what I've gathered from a few forums.

Yeah, Opteron 280 SPECfp2000:

Base: 1862
Peak: 2057

So, I dunno why the 970MP gets so high for fp_rate 2000 either. Any explanations?

Heh. Note though that it's quite likely that these tests by IBM were done with a non-Mac motherboard (hence the "est" designation).
