Hmm. Maybe the first decent indicator of whether Barcelona will run DC projects well compared with Xeon? That's impressive if true.Quote:

It seems it would be........
LS-DYNA and their special Fluent Beta are AMD's cherry-picked benchmarks. The one niche where it looks good.Quote:

hmm that benchmarks sure seems to behave strange...
8 singlecores are faster than 2 quads....
seems, it all boils down how much nodes you use... :shrug:

yeah... superpi is much more important for human life.... who cares HPC (High Perfomance Computing), eh?Quote:

Add in the clock speed advantage, the manufacturing advantage, the Q4-arriving 45nm and improved platform (Seaburg) boost, and it's hard to see how AMD digs itself out of the current hole with the K10.
There are plenty of other important server benchmarks, but it clearly looks like Barcelona will only look good on HPC ones.Quote:

ah wait thats irrelevant, it is AMD cherry picked... not valid...
No it is valid as a measure of floating point performance but it just is not representative of the entire pool of applications. AMD did not cherry pick, they simply choose to show their product in the best light... just as Intel shows SpecINT preferably because that is where they shine....Quote:

I don't focuse anything. We have others to do it here.
what funny!
now rest in peace, after the effort.
Intel +1
AMD 0
My bad... I thought your message implied something else.Quote:

Heck, what is the difference between rate and non-rate Spec benches?
the only thing i have heard of is Spec benches. There are other things to determine performance in apps.
Lets see a FULL REVIEW before any conclusions. Come on guys, only hours away, then the fanboys can play.
No wonder Cray and others want access to these processors.... they will eat up FPUs.
September 10th where are the benchmarks, lol.
Can't wait this long.
9:30 tonight we get to see the webcast of launch
London is already 10th September 01:16, hopefully it will be transmitted via internet. I'm still up to see if something comes up. So 3 hours more :(Quote:

Don't they mean Sept 10 US?
Official date/time is Sept. 10, 6:45PM
So we're talking monday evening in the US.
If it's anything like the R600, which we had to wait till the end of the launch day, then I guess we'll be waiting till the end of monday :(
LS-DYNA, being a simulation program, will naturally be floating point heavy, like most simulations (eg molecular dynamics on supercomputers).
does anyone know if game physics engines use a lot of floating point? it'd seem logical, given that computer games, especially first person shooters, do a lot of simulating of real world environments & physics, and that's only becoming more common, eg ragdoll physics for dead bodies in the source engine vs icons in doom and duke nukem 3d, and lots of fun object collisions in half life 2 (gravity gun)
some manufacturers have been known to toss results into the ring early...won't name names, but...this is an OEM pissing match, remember. :)Quote:
