Who said that? I dont remember anyone to say that at least here because the difference between kepler and fermi was massive..

I'm just gonna quote myself here:

GP104 looks remarkably similar to GM204 when you look at the block diagrams, and the white paper seems to say Pascal's major improvements are memory compression, async compute stuff, and an updated polymorph engine that now inclues simultaneous multi-projection, which is mostly related to VR.

From left to right: Fermi SM, Kepler SMX, Maxwell SMM, Pascal SM




You can clearly see the obvious difference between Fermi, Kepler, and Maxwell. But Maxwell and Pascal's SM look really quite similar if you ignore the FP64 (DP) units. Major difference being Pascal is more finely grained (64 shader cores per SM vs Maxwell's 128 shader cores per SMM). I think the L2 cache is larger in Pascal as well and there might be some other updates but you can see the basic design appears to be very similar.

I used GP100's block diagram above, but if you look at GP104's block diagram below, you'll see it's even more similar to Maxwell:

P.S I just realised JHH didnt have a jacket for once.

2 sec of Fermi/Kepler refresh/dieshrink in the OCN search engine would pull up all the people saying one should wait for 700 series or Maxwell instead of buying 600 series.

Been said before

Quote:
In short, Maxwell only offers a handful of new features compared to Kepler. Kepler itself was a natural evolution of Fermi, further building on NVIDIA’s SM design and Direct3D 11 functionality. Maxwell in turn is a smaller evolution yet.

"natural evoloution", "smaller evolution yet", " only a handful of new features"

Should I remind you that all those lasted 2 generations each and 4 years+ combined?

Yet People claim Pascal will be superseded in a year just because it is not a drastic departure from Maxwell? and not by a small chip test product like 750/750Ti but a X80 product?

So according to Anandtech, Kepler is basically a dieshrunk, refined Fermi, and Maxwell is refined Kepler, and Pascal is refined Maxwell. So Pascal is basically a refined Fermi on 16nm FF then lol

Kepler lasted 30 months (Mar 2012 to Sep 2014), and Maxwell lasted 20 months (Sep 2014 to May 2016). Maxwell also didn't have 2 generations unless you count the separate launch of GM200 as a "generation". So by that trend Pascal will last 10 months, so Volta launching in April 2017 confirmed? biggrin.gif

And really, going by historical precedence Maxwell is the odd one out, because both Kepler and Pascal launched with the x04 chip (~300mm²) first, while Maxwell debuted with GM107 (148mm²), presumably because they wanted to use it as a test bed to see how the retooled uarch would fare on 28nm after 20nm failed.

It's refinements all the way down to the Riva TNT.

Edit: Or maybe the Riva 128, since I think that was the first one to add 3D acceleration.

Yep it was the Riva 128.

So, Pascal is basically a refined Riva 128 on 16nm FF. bigeyedsmiley.png

so my 1080 is the reincarnation of my long dead Riva 128 ......................... eek.gif
