Thuban lags behind gulftown when it comes to performance/watt, and you can expect Lisbon to lag behind as well.

What difference does it make to the efficiency of the CPU if it is used for desktop, server, home, work, if it's air or watercooled if it glows, or if you stick 37 GPUs in it.

How can you make assumptions about Lisbon as the product has not been released yet?
Are you aware of the power bands available? In addition, you shouldn't compare desktop to server parts.
The point I was trying to get across was that many variables can affect performance/watt. Especially the app that is being targeted.
Because desktop and server chips are the same with a different name. People need to get that through their heads. The only difference is server parts are binned to work with lower voltages since they need to go into tiny rackmounts with 40mm fans, and they need to be more reliable so heat is a big issue.
We're not comparing it to the 920, we're comparing it to the 6 core Gulftown, that's intel's competition for Thuban/Lisbon. We're not comparing an architecture that came out 18 months ago to something that came out 2 weeks ago. 6 vs 6, apples to apples.
And you'll also notice that the Gulftown is clocked at 3.33 while Thuban at 3.2, and clock/clock Gulftown performs better, so it's a total loss on AMD's part. The only thing that saves them is price.

Just like Intel bins their Westmere xeons, AMD is going to bin their Lisbon opterons, they play the same game, just different shirt colours. The power figures that Gulftown and Thuban show now will reflect in the server parts, perhaps just a bit lower for both camps.
Actually there aren't many variables, the only variable is the one you mentioned, and it doesn't have that great of an effect. Just like comparing AMD's Evergreen efficiency to Fermi, although it varies between different games, on average Fermi is far less power efficient. Heck you might even find one game that consumes more power on AMD if you look hard enough. Good chances are the OP is looking for an average unless he runs only one specific application.
That is what I wanted. Perfect. Need to upgrade the work computers today and we do lots of sims monte carlos.
No, lisbon and thuban are different products. You'll see features in lisbon not in thuban and vice versa. They are built on a common architecture, but you can't put a Lisbon in an AM3 and call it thuban, and a thuban in a C32 is not a lisbon.
Most of performance per watt will be driven by the apps as someone correctly pointed out above. You can't make a blanket statment, you really need to know the apps.
i agree with ya however...
that price factor is just too awesome and would completely tip the scales on efficiency... were talking about 1/3 to 1/5 of the price if u look at the higher end hexcore xeons like the X5670.
And that translates to more per dollar Jag, because they are not 1/3 to 1/5th as fast as gulftown, id say about 2/3rds the speed is a good translation.
Yoxxy if u need a lot of spam machines with virtualization, you will get more work done with 2 X6 which will run you about the same as 1 gulftown.
If you need to do a lot of encoding and other things, which are intel HT optimized... then you will get more work done with 1 gulftown because of how HT works.
So Yoxxy it might be better in your sense to build 2 x6 machines for monte carlo if your going to be that heavy on virtualization.
When looking at performance without looking at price.. intel wins.
When looking at effiencency as well as dollar per performance.. im sorry.. but AMD scored on this one..
X6 pricing is just too awesome, and i hope AMD doesnt learn from intel.
No offense but you don't understand performance/watt. I can change simple cooling and increase the performance/watt. I can change hard drives and increase performance/watt. Obviously I was being facetious, but the point I was trying get across was you need to take in account other factors to give a more accurate answer. Or you can get some guy who will answer the question with some slide with 0 other info taken into account......wait....![]()
the Intel's might pay for themselves in the end while getting work done.
.
great point jag.. however i don't think your gonna see much of an end point after u counted the cost of initial from the difference between a Gulftown system vs a X6 system.
Its not half the wattage were talking about, nor is it 1/3
Most of performance per watt will be driven by the apps as someone correctly pointed out above. You can't make a blanket statment, you really need to know the apps.
That's true. Depending on the price you might have to run them for many years before you compensate for the initial cost.
Thuban is a child of Lisbon just like Bloomfield is a child of Gainestown, and their performance and power consumption will be extremely similar. You can sing your song all day, this is how it is.

There are 4 things you have to look at to give an informed answer.
Performance in the App or Apps-How big of a performance gap
Power Consumption-Actual power being consumed
Cost-Has to be included in relation to the performance. A 15% improvement doesn't warrant in some cases an additional 50% cost.
Desktops or Servers-Desktops may not require being run 24/7 so that will certainly affect power consumption over a server. A desktop also is cheaper and may be an alternative to a server. Of course this all depends on the apps and purpose of the computer.
and 5th being possible Support Costs-To extend warranties on servers cost more than a desktop. If say a hex-core Intel is providing top performance 2-3 years from now, it may in the end be cheaper to pay a little more for Intel over an AMD system right now and not have to do a complete upgrade 2 years from now, thus saving money.
And Jag87 you do know what facetious means right. You did graduate from hi skool, right. And also, they do make 1366 Xeons.
No, Thuban is a 125W TDP part. I don't know the Lisbon standard power TDP off the top of my head, but it is probably double digit.
And there is an HE (lower TDP) and an EE (significantly lower TDP) that will be available.
The 6 core EE will have a TDP down in the 35W range (which is something that we have said publicly), which puts the performance per watt in a different class. I'd be willing to bet that a 2P Lisbon platform could have a lower power draw than a single socket Thuban.
The two products are targeted at different uses.
