i think the asus one is better mobo ever donne if you want use your 2kwatts PSU over 500W :D

When I saw the northbridge I was like :eek:
AMD knows how to make a cool chipset then :D Hopefully it'll stay cool while OCing too :D
I did some digging in the AMD 10h Programmer's Manual and Intel's Programmer Manual.
Barcelona shuffle latency (PSHUFHW): 2 cycles latency
Conroe shuffle latency (PSHUFHW): 2 cycle latency
Penryn shuffle latency: 1 cycle (from super shuffle engine)
Barcelona 128bit division latency (DIV*): 16-20 cycles latency
Yonah 128bit division latency (DIVPD, DIVSD): 63 cycles latency (not a typo!)
Conroe 128bit division latency (DIVPD, DIVSD): 18 cycles latency
Penryn 128bit division latency (DIVPD, DIVSD): ~5 cycles latency (estimated from Radix-16 divider)
Barcelona 128bit square root latency (SQRT*): 21-27 cycles
Yonah 128bit square root latency (SQRT*): 118 cycles (not a typo!)
Conroe 128bit square root latency (SQRT*): 29 cycles
Penryn 128bit square root latency (SQRT*): ~9 cycles latency (estimated from Radix-16 divider)
Conclusion: Shuffle speed improvement for Penryn shouldn't make too big of a difference... 2 cycles latency was already very low. Division/sqrt isn't that common (but is common in F@H) and performance will improve accordingly.
Do you have numbers for K8 whatever latency since you have Yonah and Conroe numbers?
If someone can find the K8 programming manual, sure.
Very interesting, thanks Shadowmage. Wolfdale and Yorkfield should be Distributed Computing monsters.
For A64 latency perhaps this document could help:

AMD Phenoms will introduce to the market this Monday - 14th, with HD2xxx cards!
Kudos to Shadowmage..now thats good work :) :clap:
Yes i´ve seen... i have some slides under NDA ... and this NDA ends 14th ...
Guys I have conspiracy theory in addition to what (BTW well informed) OBR said.
Anyone with interest in F1 racing knows that tomorrow in Barcelona/Spain is next event...
By accident code name of new architecture form AMD is Barcelona!
If I would be AMD then guess what date I would choose for releasing first benchmarks to the public???
Kombatant(working for AMD as sort of PR/adviser) was hinting several times on Beyond3D forum that on 14th of May we will get very nice surprise besides R600XT... (it wont be RV630 coz, as rumor is saying, it's delayed).
On several older roadmaps Barcelona was slated for 1H launch.
Working quads was demonstrated in Monterey, California on 9th of May (AgenaFX with non-registered DDR2 DIMMS ;) 1 socket and 2 sockets configs)
THE END!!
:toast: if it's true ...
PS. I found original words from Kombatant:

Interesting/funny/controversial/stupid enough? ;)
Tnx Lightman:)
nice
14th is NDA lifting date. Products launch is still in 2H
Full review launch or just preview ala Conroe?
The 14th is x2900 series card. No K10 anywhere. Not sure how people mixed it in with it. K10 is something there will be in summer/after summer.
NDA on K10 finish on 14.
Sweet. So how about availability? They've been flip flopping on that a lot, summer, Christmas..
