The package size from Haswell-U/Y is 40x24 mm big according to the datasheet. I did a new calculation. I got for the Haswell die 126 mm² and for the Broadwell die 80 mm². It is apparently a 2+2 die.
Package size is 40x24mm for Haswell-ULT and 30x16.5mm for Broadwell-ULX. Based on the latter data, it may be easier to calculate the die size for Broadwell-ULX.
Are you sure you're measuring the right thing? The onboard eDRAM (i.e. Crystalwell, the top chip on all three packages) is 84 mm^2, so the CPU can't be so small.
"...there's still some uncertainty on whether or not we'll see a desktop Broadwell though."
No, we won't see a Broadwell for desktop. The 14nm part for the desktop will be released under the name Skylake and most likely we'll have to wait for this until late 2014 and much more possible early 2015.
I can't remember where I read this, but I thought I heard that intel was going to instead go the path of a "significant update" to Haswell in 2014. By that I assume we'll see some small to modest clock bumps.
What can we realistically expect from this new era of hybrid devices using Broadwell that we haven't already seen or hinted at already? Honest question, I was hyped for all these hybrid concepts initially but I still see myself favoring a regular laptop + cheap/small tablet... (actually went from an OG Transformer to a Nexus 7) Will Broadwell and/or this smaller package finally enable slim fanless designs that are no bulkier than the ARM tablet designs we have now?

We need something to determine scale, the chips look huge just from the pics. hahasolipsism - Wednesday, September 11, 2013 - link

The Broadwell Die is 63,4% the size of the Haswell Die in this photo. If anyone knows the package size from Haswell-Y it would help.Goty - Wednesday, September 11, 2013 - link
That is remarkably close to the numbers I just posted below. Hooray for me not screwing up!Goty - Wednesday, September 11, 2013 - link
A very rough Photoshop estimate puts the Broadwell CPU die at 114 mm^2 and the package at 590 mm^2.mikk - Wednesday, September 11, 2013 - link

Looks like we'll soon need diamond heatspreaders to keep these bad boys cool!FieryUP - Thursday, September 12, 2013 - link

The Broadwell die size from the smaller package is the same. Based on your 30x16.5mm size from the smaller package I measured 81 mm² for Broadwell.Goty - Thursday, September 12, 2013 - link

There is no eDRAM in the ULT/ULX space, at least not yet. The top chip in all three packages is the chipset/PCH.Goty - Thursday, September 12, 2013 - link
Ahh, good point.mikk - Thursday, September 12, 2013 - link
Yes I'm sure and there is no edram, the smaller thing is a chipset. Apparently still on 32nm.Novacius - Thursday, September 12, 2013 - link
Round about 82mm² seems correct for this 2+2 version.jrs77 - Thursday, September 12, 2013 - link

just the image comparison shows ~ 60% smaller lower chipUnfortunately the top chip (PCH ?) remains the same :(
