Intel's Next-Gen "Sandy Bridge" CPUs in Laptops, Desktops by Early 2011

[god_43]

The latest family of Intel microprocessors, code-named Sandy Bridge, will be in production by the end of this year, and desktops and laptops with the chips will likely be on world markets in early 2011.

looks like they ticked when they should have tocked eh?

I have a hardtime believing he quote below in the article. Really 400 million? I have a hardtime believing that intel has sold a new computer to what I guess would be a quarter of the household that exists in the world. That number has to be inflated. If we somehow changed this to cores, it starts to get alot more believable, but that still alot of processors.

"Around 400 million 45nm Nehalem processors have shipped to date, Perlmutter said during a speech at IDF."

One processor sold doesn't mean one processor to every household. Think of all the commercial applications where the processors are purchased in bulk.

[snoro]

alot of those 45nm nehalem processor might be server cpu and they do buy alot of those. Lets just says a medium sized company have a farm of 50 4processor rig. If you change all the cpu to new nehalem cpu, thats already 200 cpu sold for just one customer. Core i7 must be a very little part of that number.

Sandy Bridge sampled *in volume* in Q1 of this year. In production later this year. Intel accelerating 32nm fab build-out, will have 4 up and running in Q4 of this year.

Where's Llano?

Let alone Bulldozer...oh, that one's still on the drawing board.

[ajaidev]

No these ones are not the Sandy Bridge you all should be excited about the 6/8 core one that will come later on.

The initial ones will be dual and quad in flavor and you all should know these are based on a non tweaked version of sandy bridge, the 6/8 core one on the other hand is gonna be better.

Also dont expect a huge jump from these dual/quad sandy bridge cpu's. I expect in clock 2 clock comparison would paint a picture like dual llano < dual sandy bridge < quad llano < quad sandy sandy bridge in performance

Shipped doesn't mean sold, it only means they are in the channle or at the big oem waiting to be sold.

Westmere, Sandy Bridge, and Ivy Bridge roadmap from PC Watch.

What about threads?

Any details on the tweaks?

Hmm,let's see Llano taped out in November last year ,and BD is also in good shape (won't say it is up and running since JF will come in and deny it ).
My take on the launch of both designs is that the SB will have similar "time advantage" over BD on desktop the same way Gulftown has one over Thuban(think 1 to 4 months,depending on the launch date of SB)

ignore trolls much i do!

on topic:

i would like to see a SB llano match up; because it will be interesting? llano is not really the same core as the current Deneb's, it is more like k10.6/10.8 from all of the redesign we know about.

[terrace215]

dual llano < dual sandy bridge < quad llano < quad sandy

Basically equivalent to: "SB is not quite TWICE as good as Llano, per core", as the first and third inequalities are taken for granted.

What was your point?

[terrace215]

Oh! Llano taped out! My goodness. When was, or might we expect, first silicon? First samples to customers?

Why should anyone be more excited about a variant with more cores on die? They were always planned. Are you saying the 6/8-core versions actually have an IMPROVED core vs the 2 and 4-core versions? What do you base this claim on?

dual llano < dual sandy bridge < quad llano < quad sandy

I cant say much but when more info gets released keep an eye out for the core size and IGP size "Not the total die size"

Also Sandy Bridge is suppose to be better than Nehalem, its different in so many ways. But llano will be basically a tweaked up and reworked Deneb.

Also i did not say that dual sandy bridge = quad llano in performance. But it is very clear that quad sandy bridge will totally crush quad llano

[Mats]

I wonder if Intel will reuse the socket this time when 22 nm shows up.

terrace: It's a well known fact, everyone knows it.

Llano is a deneb core'd cpu with a 80 shader gpu integrated in it from what i remember ..... + if the rumors were true it will most likely be on 32nm .... should be decent ... but nothing to hold off those sandy bridge cpu.... bulldozer should do the trick tho .....

[YukonTrooper]

It seems like I've been hearing about Bulldozer since the turn of the new millennium.

[ajaidev]

bulldozer will not fight 2/4 core sandy bridge, llano will fight them with 2/4 and maybe 3 cores because 2/4 SB has IGP and so does llano.


Thx informal



Yes this is real die i can vouch for that cant say if the tags/info is correct tough

Huh? Bulldozer is actually in a good shape with nice architecture:

Won't there be any "tweaked" SB quad core version then? I don't want to spend a premium for the extra cores I would have no use for. Quad core will be optimal from a performance/cost point of view probably a good 2 years still if you're not folding.

No tweaked versions for dual or quad cores at least not at first.
These ones are based on a what SB would have been if AMD did not come out with bulldozer when they did.

I had PMed a slide to a few members about Intels plan to combat Bulldozer and its happening exactly the way i said well except for my FMA prediction that is.

I was told that i may get a ES of quad SB after 3-4 months so i hope i can get my hands on it first tough that would be great.

[dartaz]

This is debatable

Core i3/i5 6xx already can compete and even beat Athlon II X4 in many cases. Of course, in heavily multi-threaded Athlon II X4 wins most of the time, but the difference is not big.

We still don't know how much IPC improvement SB will get. So, let us not make quick conclusion.

However, llano is based on Deneb core (not Bulldozer), and it won't have L3 cache. So, it looks more like 32nm Athlon II to me

Basically equivalent to: "SB is not quite TWICE as good as Llano, per core", as the first and third inequalities are taken for granted.

Intel dual core SB don't have to be twice as good as Llano per core to compete with it

Remember that Sandy-bridge supports HT which can boost the performance by up to %25 - %30 in some multi-threaded applications.

Also, don't forget that not all applications use 4 threads, and some of the application that use 4 threads are not very optimized and don't show massive performance boost when having extra cores.

[kl0012]

Actually in some heavy FP algorithms it would be more then twice as fast as llano per core (when AVX is used of cause).
I think many media encoding software (and other calculation-intensive software) will be ready with AVX-optimized versions for the SB launch.

Llano will have a slightly tweaked Deneb core. They are not exactly the same although whether their differences will have any effect on performance remains to be seen. Some more information regarding the changes to the CPU core in Llano can be found here: http://citavia.blog.de/2010/02/09/so...o-die-7974978/ and some more in depth information over here: http://www.semiaccurate.com/2010/02/...nm-llano-core/.

As for the GPU in Llano, I think 480 shaders would be more likely. That would give Llano a GPU that's closer to Redwood (Radeon 5650) in performance and it will probably a much faster GPU than what's in SB. It will also have DX11 support, while SB will be stuck at DX10.

As for die size, I guess that Llano will be a little under 170 mm² in die size, which compares favorably with SB as SB will be around 225 mm². Their clock speeds will most likely be pretty similar. SB will be the faster CPU while Llano will be the better balanced package IMHO.

Now that's interesting. Could you PM me one, please?
