Nehalem Info from hkepc

[Shintai]

I wouldnt worry about DDR3 prices some 9-10 months from now. They will be very close to DDR2 prices.

[saaya]

nvram is connected via the external chipset

[largon]

Well, how about that. 192bit (trichannel) DDR3...

Say hello to near-20GB/s memory bandwidths and DDR3 trikits from every DIMM builder out there.

[OBR]

how is DDR3 on Bloomfield directly connected to CPU? I see anything else on picture ...

Hmm? There is no Bloomfield picture. But it contains 3 DDR3 channels on the IMC.

NVRAM is perhaps not the best word. Think flash.

Its already today connected via the southbridge. Either via some direct link or via USB/PCI/PCIe/SATA in the form of TurboFlash or iRAM etc.

Great info leomax

130w for bloomfield? .... ready the LN2 for home use

Not sure why you say that? My wife has a Dell Otiplex with it Prescott 670 (3.8GHz) which has a TDP of 115W. http://processorfinder.intel.com/Det...px?sSpec=SL7Z3

No it's not OC'd but her computer is very quiet and hasn't over heated in 2 years of use (including extended 100% loads while encoding video).

XS OC'ers need LN2 regardless of TDP, but the average user (even a non-OC'ing power user) can easily get proper cooling for 130W. Also, the Bloomfield chips will have their own socket LGA1366. As such, they most likely will have a completely difference reference board design.

exact same tdp as the QX9650

Only thing that surprises me is only 1.1x-1.25x on single threaded improvement? That means we won't being seeing that much of an increase except for multithreaded tasks, which is nice, but I was hoping for a big increase all around

x86 cant improve much anymore. And thats basicly what we see again and again. Core 2 was roughly 20% faster than Core and Athlon.

Also why we have the multicore race after the ended gigahertz race.

Thats the penalty of a 30 year old design. If it wasnt for shrinks we would be seriously stuck.

So 10-25% is ALOT. AMD people should know

why do they call flash memory nvram?

and tri channel mem is confusing...
the board has 4 slots... so... hows it supposed to work?

[LyP0]

complaining about the 130 tpd ... why the p4 EE used to suck more out of the wall outlet and that was a frikkin single core and way less efficient as this one.
i'm more interested in how much the normal dualcore's will use. It wont be that much i hope.

btw shintai ... good point

[LyP0]

because it is nvram (non violent ram )(Non-volatile random access memory (NVRAM) is the general name used to describe any type of random access memory which does not lose its information when power is turned off.)
atleast that's what i think

[RedBull78]

Ohh I like...30% less power than Penryn on the same process for the same performance. Thats pretty kickass when looking on Penryns already very very low usage.

Don't assume that 30% reduction only comes from the cpu, i think they formulated chipset power usage as well.

[Zytek_Fan]

Different socket between high end and performance? Bleh.
Unless LGA1366 is for the dual socket enthusiast platform...

Otherwise Nehalem looks like it's FTW!

Yep, once DDR3 becomes the memory standard (for Intel platforms anyway) the prices are sure to drop significantly

[Shintai]

It is NOT a bloomfield board layout. Bloomfield chipset would also be southbridge+northbridge.

It is a board for the Lynnfield/Havendale CPUs with only 2 channels.

3Channels is only for servers and extreme CPUs.

[Shintai]

Its the same as LGA771 vs LGA775. The Extreme editions will then be like the LGA771 and for DP etc. But yes, Extreme+server and performance+value and incompatible between.

[Shintai]

Don't assume that 30% reduction only comes from the cpu, i think they formulated chipset power usage as well.

And the change is? For me its still 30% less power. even tho 5 or 10% may come from a chipset.

I really dont care about where its saved. Just that it is saved.

We will finally say goodbye to the heatpipe madness

I´m afraid, that's impossible, you'll see

Single threaded performance is already very strong on Penryn, Core 2's biggest weakness is still multithreaded performance, in terms of per core scaling it does worse than K10. So I'm glad Nehalem addressed this weakness, whilst being able to get a substantial boost in single threaded performance as well.

Besides, as Shintai said, now that the MHz race is over, it's time for the core race. Multithreading is the future, and Nehalem with an IMC and HT should prove a monster in this regard.

waiting for penryn prices to drop like a rock so I can afford a quad with a 9x multi

Not so sure the End Product will ship with 4 slots, wouldn't be the first time the shipping product looked different than Early boards. I'd expect them to ship with 3 or 6 slots. Server boards with 9 instead of 8.

Please explain Core 2's biggest weakness again?
