Where is Core i7 Revision D0?

Tzupy · Post by **Tzupy** » Tue Mar 31, 2009 5:44 am

The D0 revision was supposed to be available since the 25th of March, but I still can't see it anywhere in stock.
Can someone please shed some light on this issue? Or it's vaporware and no point to wait for it?

While I don't know when the i7 models will show up, the equivalent S1366 Xeon CPU's have showed up all over the internet.

As you can see, both the 2.93 and the 2.66 GHz models are rated for 95 W.

These new Xeon CPU's are about to become available in Germany.

Search for i7 920 D0 and you'll find more info, some sites mention April 1 or 10.

Well, the Xeon 5570 and others are in stock at newegg, for *only* 1470$: http://www.newegg.com/Product/Product.a ... 6819117180
Since they cost 2.5x the equivalent desktop parts, I think I'll pass. I already am considering getting a SSD for my new build, and my budget is limited.
The 5520 looks however interesting, at only 380$, and it's a 60W part: http://www.newegg.com/Product/Product.a ... 6819117185
But thanks for the links anyway, maybe the D0 will show up soon.

I believe that it's an 80W part, actually. It's only the L series (e.g., L5520) that's 60W, and it's considerably more expensive.

The only place that stocks the D0 still seems to be Tankguys:
http://www.tankguys.com/intel-core-i7-920-d0.html
The part is still listed as 130W TDP. And they only ship to USA or Canada. Oh crap...

TDP means nothing, just look how the E5200 is rated for 65 W and yet it uses 25 W.
TDP is like "yeah, it's great when they lower it, but if they don't it doesn't prove anything".
I know I posted the Xeon numbers before and now say this, but AFAIK the server TDP's seems to be more accurate sometimes.

D0 920 have showed up in Japan, and that's physically, not just listed in some store

I asked a site that ships to Romania (and I already bought stuff from) when will they get the new D0. This is their answer:

The only way to get these it to be drop shipped direct from Intel once the batch is complete. If you would like to place one on order we can do that.

However, I'm not sure what they mean! 'drop shipped direct from Intel' ? Can someone please translate it for me?

Considering Intel only ships in batches of 1000 or something, I'm not sure what that means either. I'd think they still have to go through a distributor to get a single chip. I can't picture an Intel factory going through the trouble of boxing up one single CPU to ship to Romania, but in a recession like this, who knows what the companies are willing to do to get products sold.

OK, here is how it works.

Processor companies make the parts, and they all go into the warehouse. It's probably full of all their old stuff, including not only the previous rev, but dual cores, and (eeeek) even old single cores.

And to complicate matters, there is a distributor between the chip company and the retailer.

When the new, hot stuff that everyone wants starts to come off the line, everything in the warehouse starts to smell worse. So you try to push the old stuff out. The distributor does the same.

You try to deal with a FIFO inventory (first in, first out) but your customers want LIFO (last in first out).

Restrictions like "drop ship only" are designed to target parts to specific opportunities. Not that they are drop shipping them to end customers, but that they will only ship directly to the retailer if they are ordering a quantity of parts. The billing goes through the distributor, but the parts never touch their inventory, it goes straight to the retailer.

This is pretty common in a large number of businesses. The net to you is that your retailer is not buying enough so they are having to pull from distribution - and they won't have the new parts until they bleed off the old inventory.

Intel ships in batches under 1000 all day long. That is only for pricing.

I had almost given up on the D0, but suddenly it became available at OverclockersUK:
http://www.overclockers.co.uk/showprodu ... ubcat=1272
I asked someone in the UK to order it for me and then send it to Romania.

Here is the Xbitlabs review of the new D0 stepping, although not the 920, but the power draw drop is probably close to the 14W they measure.

Three things to check if you don't get the one in UK:

1 - Search for d0 on more places with Ctrl F in your browser, like here for instance. Starts at â‚¬268.
Here are two shops in Italy.

2 - The Xeon W3520 is supposed to be pretty much the same thing, although I don't know much about it. All are d0's, no c0. Checkthe thread above, they mention it there and it seems to have some drawbacks.

3 - Xbitlabs test was done with a XE part, which usually tends to use more power than regular parts at the same settings, especially under load.
Here's a test of a QX9770 that uses 114 W, and a QX9650 uses 84 W at the same clock speed.
Yeah, in this case they both happen to be a XE, but you get my point. I wouldn't be surprised if the new 920 uses less power than the underclocked 975.
