(I wish future GPU architectures also stayed on 28nm: this is so much more interesting!)

How so?
Also, Inno3D jumped the gun:

The data relating to the other video cards (both nvidia and amd) do not match with reality. videocardz has also deleted the news from its homepage

The improvement should be mostly because of the caching, considering the compute deficit of GTX980 compared to 780Ti. Now if only NV could make their mind and polish their OCL run-time.
i agree, i think was a sort of mistake of Expreview while preparing the tables or anything like that
That deficit is very much application specific. The 780 Ti requires much more ILP to hit peak utilization. In workloads with few opportunities to dual-issue math instructions the 980 has a ~40% advantage.
How is that different in Maxwell, since both architectures are dual-issue?
Tom Peterson's talk on G-Sync back on August 22 (youtube/pcper) was pretty explicit about having "no plans to support that [1.2a optional extensions / adaptive sync]" (51:37). Separately he also mentioned that "obviously we're [NVidia's] looking at that [multiple DP outs] for future products."
For those asking what happened to Expreview review, I was asked by them to take it down, but fear no more, another review just got leaked, with even more charts, slides andeven pictures of unreleased cards. Enjoy.

Seems like there's a chance it'll support DX12 feature level 12 - the leaked slides mention conservative rasterization. It also looks like they're supporting voxel based global illumination algorithms with some sort of hardware acceleration. Finally, they mention something called "shader: raster ordered view". Anyone know what that is?
All in all, looks yummy.

How is G-Sync technically different anyway? Wouldn't surprise me if nvidia could enable FreeSync with a driver update. (But of course they won't for now, no reason to alienate their monitor manufacturing partners.)
Can you elaborate more (or quote exactly what they said)? I can't currently view the page and I'm wondering if it's pixel shader ordering (like conservative rasterization, another new feature in 12_0). Perhaps it really is a feature level 12_0 card.
Now I'm interested!
Sadly, that is a direct quote:

What we need is more than just the slide ;^>
Sadly, I don't know enough about both to do a compare, but I got the sense that with FreeSync, the driver is in control of when the monitor comes out of vblank/starts next scan, while G-Sync does the work of managing that for the driver.
I think the way to work out nvidia's gameplan here is to watch what they do with mobile/laptops. There were intimations in that video that nvidia will have gsync-related announcement for mobile, and given that edp is already there, I'll be curious how the tech winds up working....
