Just tick tick tock, tickity tick tick tock.....can't wait for the Ivy Bridge stuff! Hopefully will be small, power efficient, powerful, highly over clockable, and cheaper!

I'm thinking the onboard GPU, especially as it has been commented is not up to the most demanding games, thereofre a crunching machine would not need to ahve a top-end graphics card as it won't be used for games, will therefore be an excellent solution for CUDA. Especialy with the S variations using as little as 35W.

Anything that underpowered though will be well out paced by cheaper video cards in an older machine. It may be ok if it's what you got but I don't believe it will be preferred. As far as crunching power the upper end cards are needed because of the extra shader's that actually do the processing.

As of right now as far as gpu power on those chips(i5-2500k) are showing about half the performance of the GeForce GT 430. I don't think you should be totally concerned at power consumption. The Sandy Bridge at 35 watts is way lower than the GT 430's 94 watts(176 under load) but is producing a little less than a third of the work at a time. This would mean if it was getting all the work done it would need to be a 85-90+ watt part(by guesstimation). As far as number crunching I would bet it would be more than double. Some of the folding guys have reported they are averaging about 7000-8000 PPD on the 430, I wouldn't see the integrated chip, if it could run Seti@Home on it, getting more than 1,000. But who knows and time will tell.

Not to mention upgrading an existing i7 machine to a new i7 would cost someone at least ~$180(LOW LOW Range) where as a GT 430 costs less than $100 and produces more WUs. Each to his own I'll stick to dedicated processing.

To -BeNt-: Excellent graphics to show all the baseline of CPU performance.

Also, to get better performance per dollar, you should wait at least a couple of months or so. To get the best ratio, wait another year. And so on.

Yeah but the one thing. There is always a better option out there. With the release of graphics cards and processors if you wait more than a year you will have something better come along within 6-10 months. Especially at the rate things are going now, even though it does feel it has slowed a bit. So while you are getting more bang for the buck you actually aren't since the matrix has changed by that point in time. Take gas prices, 10 years ago if you told someone $2 a gallon isn't that bad to pay for gas they would have laughed you out of the room.(At the time gas was $.89 here, and now it's $2.90) So value per result is all speculative and relative. So buy what you feel is the best when you are ready to buy!

Back in 1978-1980 most computers could only do simple graphics and text, We've come a long ways since then and I watched It all unfold.

As to P67 motherboards, eVGA is making a P67 Classified 200 Motherboard, I'd have loved to have a state of the art cpu and motherboard, But I'll settle for 1156 technology and some water, that stuff is heavy too.

Yeah you aren't the only one that watched that, it has been an amazing ride to where we are now. It seems that the processor and graphics world are starting to hit a wall like the speed wall previously when we went to multiple cores. It's truly going to be awesome to see what happens in the next 5 years with everything, I want to see AMD come out with a 'Core' type design that totally changes their product and get hyper competitive again.

As far as settling for 1156, if I'm going to settle it's will be staying with top of the line old generation stuff until I can afford or want to afford current state of the art parts. Hence the reason I'm still on 775 quad because performance in everything else would be negligible, and crunching is really an after thought for me. When I build machines I hate going 'good' enough when I know perfect, within reason, is out there.

I want the best for the buck.

Me too. But since I have to pay for a processor only once, but for my power bill every month, I think I will update my AMD Phenom II X4 965 in the near future to a Intel 2600K ;)

Keep in mind a new board for that CPU will likely start at around $250 vs AMD's at around $80...

Not to mention triple channel ram. The monthly difference on your bill from a 65nm to 45nm chip will not be really noticed. It would take a MASSIVE difference for me to pay attention to it, whats $5 a month or less.

?
The new chipsets are all Dual Channel.
Word is that the new high end chipsets will be Quad Channel.

And as to power consumption
"To put a really fine point on the comparison between Intel's quad cores and AMD's, consider that the Core i7-2600K config needs under half the energy that the Phenom II X4 975 system does to accomplish the same work."
50% less power is a significant reduction.
Ref.

And if your monthly power bill runs in to the $1,000s (or 10,000s), even a 5% saving would be significant.

Yeah I misquoted, 1155 is going to be dual 2011 is going to be quad channel.

You need to re-read the link you posted though. Loaded power consumption of a i7-2600k should be around 144 watts where as an AMD 1100T will be 192 watts. I don't believe that's half the power? That's about 25% less power. While this is substantial to people who are using desktop processors in a datacenter, read eh, it's not that important to a home user. You power consumption mainly comes from the rating on the power supply as it's possible for a 1000 watt 80+ gold psu to actually use less power than a none 80+ 500 watt.

I'm running on a 775 PC that I built, It's a few years old and is having problems with sound, SoundMax stutters and I've tried different drivers, It still stutters, So I'm going to do some work soon, As in transplanting some old and new parts, As I just got in some ram(6GB) and a 2.5" to 3.5" adapter for the 2.5" 300GB Velociraptor hdd, It may not run as fast as an SSD, But It'll last longer I'd think. I'm also going to Win 7.

- the way they work out the efficiency is not just the power consumed, but the time it takes to do the task.
The new CPUs use less power, and take less time to to the task than the existing AMD ones. End result, 50% less energy required to do the same work.

You can work it any way you want, but watts are watts. "Working efficiency" is not the same as power efficiency over a giving amount of time. IE watts. Of course a faster chip will produce more work. Hell my 775 quad used less power and produced more work than my FX-60, still doesn't change the fact of the difference in watts. Don't get bite by the hype that is surrounding another chip release, because if you think they are going to be another 50% faster than anything out there you are dead wrong.

*Edit*
You know what I went back a re-read that entire article again. And the funny thing is when you get down to the part you specifically point out, "task energy". You may want to take a closer look.

i7-2600k - 8.5
Phenom II 1100T - 14.0

Thats still ~25%, coming in at 30%. Not far behind or off the power consumption numbers. Still nowhere near 50% though. Remember compare generation to generation not hype versus whatever it beats. IE comparing it to a Phenom II x2 565 etc.

If you want a serious look at the numbers check out this review Specifically they Dhrystone, Whetstone portion of it. It aligns more with your argument, especially when the chip is overclocked to 4.3 Ghz. It does show it out performs anything AMD by almost two fold, however doesn't start hyping the number per watt and all that.

hotze33 has posted on Einstein about his new Sandy Bridge host: in this thread. He seems pretty happy, and reports encouraging system level power consumption numbers.

Wow looking really good for sure. Can't wait to see someone put a nice one together for Seti@Home. Can't wait to end up seeing what Ivy Bridge brings now!

Interesting, I discovered by ding a little research that the Sandy Bridge K models have as much Virtualization routines as an i5 750/760 cpu does and no more, My i7 860 has a full set and yes I do have an i5 750 cpu, I'm in the midst of doing an intermediate upgrade(the i5 750 and the Asus P7P55D Pro motherboard will eventually be an HTPC-TV to replace a hand Me down PC that does that function now). Both PCs will have Windows 7 on them, Premium for the HTPC and Pro for the water cooled HULK. That HULK will have 6 GTX295 v2 cards(single PCB type), But I have to get a house, Then 3 water blocks for the 295 cards that I lack, plus fittings and a last v2 GTX295 card, I'd originally bought 6 cards, But one was a ripoff as I'd paid for It and never received It or a reply to an email I'd sent on ebay, I did get My money back though, The seller got a -1 for feedback.

So... I have a host running 4 s@h WUs in parallel, pulling less than 45W total and that's including the UPS and various other peripherals...

What's more important is the Watt-hours per WU...
