Sandy Bridge NDA Change

Sandy Bridge official NDA lifted today Jan 2, 2011 at midnight, get reading reviews and report back with projected TPF's. I was going to go to bed early but now this.

Why do the K versions include more GPU cores? No one will be able to use them on their P67 boards. P67 is the only way to overclock? :confused: Edit: Z68

i7-2600S can run at 3.8ghz on all four cores and has a TDP of 65W.

mobile quads hit over 3 ghz on all four cores and with the IPC improvements that should be good for 15-25kppd on bigadv. In a laptop!

LGA 2011 in Q4 but no mention of anything greater than hex cores.

4.6ghz+ 24/7 here we come! The question is with 1.5V core volatages giving such low temperatures, is it safe?

From review indications, Z68 will add oc support and the display stuff. Only that chipset can do both.

I believe 8-core CPUs will be introduced with the Ivy Bridge generation later on, which will use Intel's 22nm manufacturing process.
 
How does this result compare to an i7 hex-core average TPF @4.0GHz+ with standard SMP WUs?

Article says a p6054 unit was used.. screenshot shows a p6068. *nitpicks*

Yeah, the benchmark WU is probably out of date and that screen shot was probably taken on a current WU. *whistles softly*
 
I guess integrated graphics are actually a bonus for dedicated boxen.
 
damn they pushed LGA-2011 back to Q4? doubt thats going to happen. no way would Intel allow AMD to release the bulldozer before the LGA-2011 Sandy Bridge.

Trust me, if Bulldozer catches Intel by surprise you'll see S2011 sooner than that unless something unexpected occurs.
 
Looks like 4.8+ghz for folding. Sandy Bridge might come close to 32nm hex cores in ppd and specially ppd/w. It all depends on how well the software works with the new arcitecture.

LGA2011 wasn't expected before Q4 in the first place. This is not a surprise. As for Bulldozer, I suspect it'll have enough trouble keeping up with the existing Nehalem architecture, let alone Sandy Bridge once that hits the server market.

its faster then stock hex cores but overclocked above 4.3Ghz the hex's are still about 10-30k PPD higher.

take a look at the chart. filters 4.3ghz 980X does about 64k PPD with a P2686 WU.
 
At high oc's it uses the same amount of power as an i7 950 at stock.

I love it. My 2600k is sitting here pounding away on a p6701 at 4.7GHz with more voltage than it needs. With a 6950, an H50 in push/pull, and a third 120mm fan, it's pulling 202-203w.

That comparison means nothing, since we only know how well Sandy Bridge does with standard SMP units, not -bigadv.
 
I see that they are doing some benchmarking on regular smp units, but I would be curious to see the actual results of a 2600k @ 4.9ghz on a bigadv wu.
 
See the links in sirmonkey's post - these are actual bigadv units from the benchmark app. Wickedly9 was nice enough to run some testing for us. The short version - 24:52 for the 6900 and 24:55 for the 2686, which equates to just under 50K ppd. Also, the machine only pulls 210W.
 
The 210 watts is the key figure here. Even at max clocks the 2600k uses as much power as an i7 950 at stock clocks. The efficiency is hugely improved so that these quads use 100+ watts less than 45nm quads when OC'd.

Big win i'd say. About $100 of savings over a year here in Canada.

Goodness........

Those numbers almost exactly match my Gulftown in folding2@3.6ghz...........

Damn it. For those non hyper folders 10 million points is a nice goal to reach.

That is actually my goal for the forseable future.

On that machine we are talking about 200 days of bigadvs or about $100 of power + $600 of upgrade costs from a Q6600 system (less actually if reusing case and PSU).

Total $700 system + power.

For a dedicated Q6600 (assume same 200Watts and a good OC) we are talking 2,000 days and total cost of $1,000 of power alone.

Let's say it actually takes 4 times more to get to 10 million. Then we are talking about the same $1000 .

Of course it would only take 3 years less to reach the objective.

Now if the wife only understood logic :p

Tell her the new computer is for her, and then borg it by installing FAH as a service while she isn't looking. Also tell her that the computer can't ever be turned off.
