Just before a couple of key Ivy Bridge disclosures, Mooly Eden held up a wafer of 22nm Ivy Bridge CPUs. Presumably these are quad-core versions with 16 EUs, the largest version Intel will make at least at launch. Mooly mentioned that Ivy Bridge will have more than a billion transistors (obviously, SNB was 995M), but he wouldn't reveal the actual count.
Knowing that these wafers are 300mm in diameter, you should be able to get a decent idea of Ivy Bridge die size based on the photo below.
I seem to count approximately 37 die up and 15 die across, which would put a single Ivy Bridge die at 8.1mm x 20mm or around 162mm^2. A 32nm quad-core Sandy Bridge die is 216mm^2 by comparison.

Don't we see smaller dies every time Intel does a tick, and larger ones on the tock?Both yields and total wafers produced are lower at the start of a tick, so Intel needs to keep die sizes down to get the volume they need. In addition it gives them the die area growth room they need for the new features that will be coming out with the next tock.
Beyond that, just looking at the size of dies at a single core count is partially missing the point if some price points get more cores with the new generation than the old.

Remember than HD2000 which has 6 EU beats Clarkdale GPU. And we know that Clarkdale GPU has 12 EU like HD3000The older GMA 4500 has 10 EU
So, in other words EU doesn't mean anything when you compare older GPU architecture to a newer one.

Showing off Ivy Bridge just when I am considering getting a i7-2600K (because Bulldozer is most likely delayed), well that's just evil!marc1000 - Tuesday, May 31, 2011 - link
well, I was waiting for Z68 to buy a SB system. the Z68 launched only a couple weeks ago. Now I decided that I may perfectly wait until Ivy Bridge, because if my Penryn lasted this long, it can survive just a few more quarters...Mr Perfect - Tuesday, May 31, 2011 - link
Don't wait to long. :) I've been doing the same thing with my Toledo(points if you remember what that was), and it's really hit rock bottom now.Touche - Tuesday, May 31, 2011 - link
I don't think you spammed the front page enough. Please, put a few dozen more articles from Computex, every item/topic/hint/rumour separately, of course.FaaR - Tuesday, May 31, 2011 - link
What are you complaining about, want your money back or something? Oh, that's right, you never paid any. Anandtech is free.So why don't you pipe down for a bit ok, because if you're unhappy with the service given or the contents (both free, as already mentioned), you're welcome to start your own hardware news and review website plus forum, buy plane tickets and hotel room to Taiwan to attend Computex and so on.
Good luck with that.

Tip: On the front page, click on "Just Reviews" then you won't have to be subjected to all this heinous tech news that is plaguing the site.PlasmaBomb - Tuesday, May 31, 2011 - link
About 1.5 billion transistors then?
