The Sandy Bridge Preview (Anand)

[saaya]

Well, if I understood the story on Anand's, non-K cpus will have 2 multis above turbo, and several MHZ of "FSB" to play with. So you will still be able to get ~4 GHz from 3.1 GHz CPU. Not bad for 24/7 OC for sure..

..unless K CPUs work at 4.5 on air

4ghz only sounds good with the ipc boost... as current chips reach above 4g easily, some are close to 5g on air...

[R101]

Yep, if you OC it will be hardly justified to upgrade from current i-3/5/7 generation without getting 'K' or 8-threaded models.

For Core 2 upgraders, however..

Where did that 2 multis came from?

[RaV[666]]

That would be 3.78Ghz for a core i5 2400 ?
Turbo clock of 3.4ghz so 2x multi more equals 36x plus a 5mhz increase on the bus speed.
And a whooping 4.095Ghz for a 2500 non K model ?
If thats true, it seems like a serious pushback of oc wall.These things will probably clock near 5ghz on good air.

Anand said it..

Secondly, some regular Sandy Bridge processors will have partially unlocked multipliers. The idea is that you take your highest turbo multiplier, add a few more bins on top of that, and that’ll be your maximum multiplier. It gives some overclocking headroom, but not limitless. Intel is still working out the details for how far you can go with these partially unlocked parts, but I’ve chimed in with my opinion and hopefully we’ll see something reasonable come from the company. I am hopeful that these partially unlocked parts will have enough multipliers available to make for decent overclocks.

[RaV[666]]

There is not any mention of "2x" multis more.Only "Few" , it can mean 2x or 9x.But giving us more than 2-3x would not make sense for them.We will see.

Honestly if the 2500k is priced around $200-250 as expected, I don't think it's that big of a deal if Intel remedies the memory issue. Especially once you consider that motherboard prices *should* drop quite a lot considering that these chips are low power, so they don't need an uber special VRM, and fsb overclocking is no longer an option, so the NB much be quite simplified (meaning they'll be cheaper to produce and also run cooler, so no need for massive heatpipes beyond the looks).

Unless if you are a major contributor to one of the folding teams here, you really don't need above 4 threads. And besides HT shown to hurt single threaded performance anyways, so I would rather have 2500k for performance reasons over the 2600k in the first place.

[RaV[666]]

Well, anand states that 2500(k) will cost around 200$.
But its not like its going to price 2500 200$ and 2500K 209$ ;-).
And high intel mobo costs are associated with Intel too .
http://www.anandtech.com/show/2824

Intel gets 7$ per lga socket ,and 43$-73$ per chipset.
Thats a nehalem era.
With sandybridge it looks like differentation will be even more between Hxx / Pxx and future 2011 socket chipset.Basically you need to buy Pxx chipset because of the memory lock on the Hxx chipsets from now on.
So el cheapo sandybridge motherboards with any decent oc capabilities are probably not gonna happen.

I wonder if i7-2930 is going to replace i7-930 in its price point. Now if only LGA2011 MB will have the same price range as LGA 1366 MB then that would be a good cpu line replacement.

I don't know if it has been posted already,but Anand updated his preview article(Conclusion) with a new info on integrated GPU:

(Update: it looks like we may have had a 12 EU part from the start)

Well thanks a lot Anand for getting everyone all worked up.
Just don't come back in a few days and tell everyone turbo was on too...

[Florinmocanu]

So probably Bobcat will go toe-to-toe with mobile SB in GPU department, but my impression is that the AMD GPU will go on top overall, especially in terms of image quality/drivers/ etc.

i2600 is the only SB "Mainstream" cpu with 4 + 4 8 threads :/

[LightSpeed]

I was thinking 12EU from the start too, that performance with 6 EU seemed too good to be true

Still, a healthy boost compared to the previous gen and great performance for a integrated GPU, especially from intel

[AliG]

i2600 is the only SB "Mainstream" cpu with 4 + 4 8 threads :/

Which is a nice upgrade for someone like me that has an AM2 cpu, but I don't think it's worth the $500+ price tag. I'll most likely get the 2500k unless if AMD releases some actual bulldozer benchmarks showing it's close in ipc but clocks much higher

i7 2990 - 8c/16T 3.46ghz (3.8ghz turbo)?

thats insane

[spursindonesia]

I don't know if it has been posted already,but Anand updated his preview article(Conclusion) with a new info on integrated GPU:

Huh, i've suspected all along, yes Intel made relatively good progress on integrated graphic front the last few years (with some acquisition of companies and personals), but the results are just other worldly for their standard, if it's really a 6 EU part. Now it seems more credible, still a pretty good improvement over the current gen, but not such a quantum leap as speculated before.

Well thanks a lot Anand for getting everyone all worked up.

LOL, gotta scrub & massage the hand that feed you, cause that's where company money comes all along, right ?

[mAJORD]

So I guess IGP may be around Ontario performance after all

http://www.anandtech.com/show/3885/s...raphics-update

this performance preview, ~5 months before launch, wasn't officially sanctioned or supported by Intel.

I told you all that even anandtech cant break NDA. My partial NDA will expire soon most likely then you all can get some insight to the architecture...

[saaya]

I don't know if it has been posted already,but Anand updated his preview article(Conclusion) with a new info on integrated GPU:

wtg anand! hope you get an extra bonus from intel for this pr stunt...

even if it would have been a 6eu part it wouldnt have made a real difference... for laptops but nothing else...
now that it turns out that this is more or less as good as it gets (some turbo boosts but thatll suck for laptops) i dont see sb killing the laptop discrete gpu market...

im waiting for the next update about turbo actually being enabled for sb in his benchmarks ^^

this screen is only speculation from Czech pcweb.

Why ?

Intel has 32nm Westmere with 6 cores and 3.33GHz w/o turbo now .
In 1 years time, the 32nm process would be 2 years old, yields at a maximum, so is the performance and all the costs amortized.

If AMD brings a Bulldozer in the field, Intel will bring a battleship with 8 16" hyperthreaded main guns.

You can also say if AMD brings in a Bulldozer, Intel will have a sandy bridge that the bulldozer cant cross... get it
