AMD Ryzen Chips 10% Smaller When Compared to Intel Skylake Dies
AMD states its upcoming Ryzen core fits into a 10 percent smaller die area than Intel’s currently shipping second-generation 14nm processor. Analysts and even Intel engineers in the session said the Zen core is clearly competitive though many confidential variables will determine whether the die advantage translates into lower cost for AMD reports eetimes.
EEtimes: The paper detailed techniques AMD used to reduce switching capacitance by 15 percent compared to its existing chips. For example, Zen marked AMD’s first use of a metal-insulator-metal capacitor which helped lower operating voltages and provide greater per-core voltage and frequency control.
Engineers tracked on a weekly basis power benchmarks on high activity regions for more than a year to reduce switching capacitance. The company now has two eight-core designs running with simultaneous multithreading at 3.4 GHz.
Hilbert: one thing they are not taking into account is the lacking integrated GPU. On Intels side it eats up nearly a third of the die space. For AMD, they do not use an IGP - the entire die size is thus used for the actual processors.

That sounds wrong. There is no way that GloFo or anyone else has a better 14nm than Intel.
Nothing to do with iGPU 
It simply means Ryzen on its GloFo 14nm process is slightly more denser than Intel's 14nm process despite Intel 14nm is slightly superior to GloFo 14nm process.

No way it's 49mm2 with an iGPU on it. These are numbers per CPU core.
Likely this.

I wonder if this has a negative effect on heat dissipation, I wonder what TPD's we're talking about in those two models.
Also, if Intel's chip uses less size for a core than AMD's does that somewhat work in conjunction with AMD's lower IPC, because smaller chip with bigger cores = less cores = less IPC?

No it's not - Intel's process is more dense, it shows the specifications of it in the graph in the article. AMD's architecture is clearly more "compact" requiring less transistors for (hopefully) the same performance. This probably also factors into the power being lower.

I think the bigger effect on heat dissipation is lack of iGPU - but big Zen is also 8/16 so those chips will probably be similar in size to Intel's 4/8 + iGPU (since Zen doesn't have an iGPU). This is only a 4mm2 difference and less transistors should mean lower power anyway. Either way I don't think it's going to be an issue - as long as AMD doesn't glue their headspreader on with a 30 meter gap like Intel does.
As far as the second paragraph - Intel uses more size for a core, it's unknown whether that core is faster or not though. Also both companies seem to have no problem fitting up to 16+ cores and whatnot, so I don't think the difference is going to factor much into the total core count.
