Dual Core/GT2 Ivy Bridge Die Measured: ~121mm^2
 

I mentioned Intel's desired secrecy around die sizes and transistor counts for the majority of the Ivy Bridge lineup in our 3470 review from this morning. While I can't count individual transistors in the Core i7-3517U that was in ASUS' Zenbook Prime UX21A we reviewed a week ago, I can measure its exposed die.

Mobile CPUs rarely feature integrated heatspreaders, giving us direct access to the back side of the processor die itself. The dual-core die looks very similar to the quad-core die, it's just not as long. Armed with a pair of digital calipers, I can get a good idea of the CPU's die area.
