Sandy Bridge CPU lineup

Hopefully this hasn't been posted already...

Looks like they gimped the i7-2620m's clocks to avoid the i7-2720QM vs. i7-2620m debates.

 

nice ghz bump on all cpus.
really a shame i cant use them on my pm55

 

Need an X202 with these. The TDP is 35W for these, but with Sandy Bridge the TDP includes the cpu/gpu/northbridge/, so not sure how it compares to a 35W Arrandale.

Also, what is the difference between the lowercase "m" and the uppercase "M, typo? Seems the number 2 was added in front to represent a new generation (Core i5- 2520M).

 

The Quads got a decent bump but the Dual-cores just got rounded up to the nearest whole number. i5's do Turbo better though.

IGP got shrunk to 32nm but it's twice as "powerful" so I get why the TDP stayed the same. The TDP numbers not changing for the quads makes sense too since they got a Mhz bump and the IGP.


I still find Fusion more interesting (not saying better, just interesting).

 

This wasn't posted. The site says ULV's will be launched later again:


See this thread for more Huron River details.

 

yeah as it stands the 2720qm will be faster than the 940xm

 

Suprised that intel's offering 35w desktop processors, and is there any word on ULV versions?

 

i can't wait for the i7-2620M

and seems there will be both LV and ULV versions

 

question: how do LV intel processors compare with underclocked normal intel processors?

 

You have got to be freakin' joking, right?! I just buy a new notebook with a 720QM, and this comes out?!! *$$&%#&%$@^%$#*&^! &%%$^$#&^$*&^%*&^%$!!!!!



/RAGE.

They look pretty good though. Maybe I will have to get an even newer notebook with one of these.

 

CZX, man, 720QM still runs circles around mine..lol. I'm still on C2D T5500, P9500, and T9800. Oh, and an Atom Z520, which the i7 makes look like the processor of a high end calculator.

The thing I'm not happy about is the stupid numbering scheme. I mean, really?!

 

Yeah, agreed. It's going to be real confusing, especially since our current correlating processors have different clockspeeds vs the new ones...

 

Actually looking at this lineup it does look like Intel have tried to rationalise a very confusing naming definition for their processors. Still pretty confusing though.

Sandy Bridge is an evolution of Nehalem with a die shrink that should bring big benefits to clock speeds and TDP's. I guess that's why were seeing such a leap for quad core cpu's.

Question is, when are they going to be available in mobile form factor? Usually seems to take about 9 months from initially launching the CPU range through to the mobile version plus another couple of months for laptop manufacturers to ramp up production of new model ranges. Based on Nehalem release I wouldn't expect to see the first mobile based Sandy Bridge laptops out till summer 2011 at the earliest.

Unless the rumours are true about Intel intending to launch the mobile variants much earlier this time?

Anyone else noticed a tightening in supply of i7 notebooks particularly high end models? I've been looking to purchase a Thinkpad x201s (it's been withdrawn) and it appears in the UK that HP have stopped selling their 'W' range (8540w etc).

 

finally i can choose a quad mobile cpu with 32nm decent clock speeds time to ditch duals besides in 2k11 most apps will need more than 2 cores

i also want to upgrade my desktops from phenom II x4 945 any idea whats the price of 3.4ghz SB quad with 4c/8t i really hope usd 274 like i7 860 or less

 

Sandy bridge is not a die shrink. It uses the same 32nm manufacturing process as Westmere (latest generation of Nehalems) and is in fact a re-architecture rather than evolution. It is the "Tock" in intel's Tick-Tock cycle. Arrandale was the "Tick" (Die shrink / evolution) for mobile nehalems.

He's probably referring to how the quad cores got a die shrink.

 

See my thread , I posted info on this. Intel is making sure that when Sandy Bridge launches there are no cpu shortages again like there were with Arrandale. After they launch, they will be readily available.

i7-2720QM, yummy :]

As it was to be expected it'll be a pretty big leap for quad core CPUs that'll benefit from the new design & 32nm at last.

 

what will be the tdp of these processors if you turn off the integrated graphics?

 

TDP is not power consumption. But it would probably depend on the situation. If you're using something GPU intensive, obviously a discrete card will draw more power than an integrated one, while on CPU intensive programs, I'd assume the power consumption would be similar since it would just Turbo Boost.

 

Speaking of power consumption, would idle power draw drop? Can we expect a small increase in battery performance?

 

With more efficient power gating, it might.

 

Intel skipping USB 3.0 again?

 

They don't care about it, they are pushing Light Peak.

 

how do you measure power consumption of cpus? i just use tdp right now to get a sense of how different cpus compare with power consumption

 

is it me for does intel CPU lineup become more and more confusing as the years go on? Because really i'm confused.

 

You and me both. I think Intel's PR team is on crack. IDK WTH is up with that chart. I spent 10 minutes of my life trying to figure out what corresponds to what, and that's time that's just not recoverable.

Do you have a rough time frame as to when Intel is looking to deploy Light Peak?

 

If it wasn't for the "S" "T" & such special features fitted in the lineup it would be clear enough imo (the higher the better, more or less) but for now it's quite messy for the average consumer.

 

Yes, 2011:

 

TDP doesn't measure power consumption, so it's not good to use it to compare CPUs. Generally, within the same architecture, the higher the frequency and more cache, will consume more power typically in a linear fashion, while more cores, tends to consume more power than increases in speed. It's difficult to get accurate figures unless you have tools such as a Kill-a-Watt and several samples.

 

thanks, but i also notice that there are "groups", 35, 45, and 55, is it safe to assume that the 35's all consume roughly the same power, and then the 45's consume approximately 45/35 = approx. 1.3x more power?

also, how do you shut off the integrated graphics and use dedicated instead now that the gpu is on the same die as the cpu? i'm mainly interested in knowing, with respect to power consumption, how my c2d p8700 with a tdp of 25w (which does not include the tdp of the integrated graphics) compares to the 35w/45w tdp sandy bridge cpu that includes the tdp of the integrated graphics

 

Overall a Sandy Bridge system should use less power than your P8700 since the TDP of a 35W Sandy Bridge includes the cpu, the graphics, and the southbridge all on the same die while the P8700 is 25W for the cpu, 12W for the graphics, than 8-10W for the southbridge, (estimates).

 

if the southbridge is on the cpu what does the chipset contain.

BTW I am disappointed with these cpu's. I was hoping for a quad core at 35w tdp.if you compare clarksfield to this, there is a die shrink plus 32nm process must be really matured so intel should be able to do better than this.I am sure we will see a fusion with 35w tdp.

I think I will wait for either ivy bridge or preferably 2nd gen fusion based on bulldozer platform(though it may be a while before we see that). I have not considered amd since core duo and would like to see them do well.

 

There is still at least the northbridge.

 

Check Intel's ARK for details on what is in the chipsets and CPUs. Don't forget that they increased the clockspeed (especially the turbo speed) and added in integrated graphics... also marketing wouldn't lower the TDP as to maintain different "TDP classes" of CPU.

 

Northbridge(memory controller hub) had been integrated with nehalem. Of course arrandale had it with gfx die but still part of cpu. SB with single die intregrate it directly with cpu.

I dont believe SB integrates Southbridge(IO Hub). That will continue to be part of chipset.

 

I know GPU does add to TDP. May be I am expecting too much. But if AMD can make 35w quad core with fusion(much better gfx), intel with mature 32nm process could have done the same.

 

hmm, 35w quad core with fusion? that sounds better than sandy bridge's power consumption, is it because it's clocked lower? or.. because south/north bridge (dont know which) is not integrated like with sandy bridge? or does the fusion graphics perform better AND consume less power?

btw, how do we know that fusion will have better graphics?

 

See thread for Fusion info.

 

IMO, AMD's mobile CPU will nver be close to intel sandy bridge quad if they keep on stinging on cache etc..

 

Is Intel expecting to double their GMA's power every time they release a new generation? I feel kinda bad, because really I could've waited to buy something Sandy Bridge based instead of Arrandale.

 

I certainly like the trend. I hope they do. It's probably a response to Fusion though, with Intel trying to be at least marginally competitive with integrated graphics when Fusion makes it's debut. They're just starting early.

 

You can't compare cache directly since the processor architecture is different and hence AMD doesn't require such a big cache. Also, TDP might not be comparable, since I remember a while back Intel and AMD measured TDP differently...

 

So the question is ... if you could wait a few months (nov/dec) for a replacement laptop (i5 /entry level i7) is it worth waiting for this or will we realistically not see any actual laptops on the streets before January?

The 32mn quad cores just seem so future proof, esp since I'd assume real switchable graphics from ATI by that time.

 

Unless you know the right people in Asia, you will not be seeing these until January. My advice is the same as regarding other new features: buy a laptop when you need it -- no sooner and no later. If you don't need one now, it's worth waiting for.

 

Just because there is integrated graphics w/ the CPUs, doesn't mean that laptops will have switchable graphics.

 

What I'm suggesting is that ATI must be working on a Optimus like system by the time their 6000 series cards are out.

 

The i7-2720QM would appear to be the best option as far the new mobile quads go (performance and possibly price wise).
But, as expected, this one is a refresh of an existing generation with increase to speeds and lower TDP.

Perhaps I should wait until 2012 when Ivy Bridge comes out and maybe then I can get a mobile 6 core cpu (or even 8 core).
Need more power for 3ds Max, and I'd prefer to wait so I can actually get tech which is newer.
