EDIT: Just noticed a contradiction in the article: in the text, they say they were able to run Just Cause 3 at 1080p with ~30 fps, which would be decent. However, in an image caption they say it was Just Cause 2 they used for the benchmark - and that would be far less impressive.
I saw that too. Pretty sure that was a typo on their part, because every other article mentions only Just Cause 3.

It's 128MB of embedded eDRAM (essentially just mega-fast RAM) right on the CPU. It uses the DDR4 system RAM as VRAM (as all integrated cards do). Previous iGPU's had 0 ram embedded on the chip.
A similar system is the Xbox One, which has 128 mb (forget exact number?) of ultrafast embedded RAM, and then a further 8 GB of usable system/vram
Yeah, as far as I know that's not really been done before. The iGPU's actually got its own on-die superfast RAM. I'm really interested to see how it performs when real world users can actually get their hands on it.
Xbone has 32MB of ESRAM; it's actually next to the APU, not on it, or at least that's how I remember it being explained. So probably not as fast as the on-die eDRAM Intel is using. I know some developers have pointed out the ESRAM is great for boosting performance of certain things, but there just plain isn't enough of it to make a big difference. That might factor into Intel's making 128MB available.
Probably the biggest takeaway is Intel has been bullpopsnizzleting in white papers and subsequently underdelivering on their iGPUs for a very, very long time. This looks like the first time they're going to meet or exceed the hype. I think they're finally getting a handle on graphics.
