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.
