[Tech4Gamers] nVidia shows off Pascal at GTC 2015 - Page 9

post #81 of 229
just in time for my massive tax refund when I'll be building my new computer smile.gif
post #82 of 229
And this is exactly why I did not buy a 980 Ti. Going to be less then 1 year and that card will be dated compared to Pascal.

So, Nvidia can charge $$$ for a low-budget gpu, no thx...

Now, bring back a kick-azz GTX-1060, not this GT-610 in GTX-660 in sheep clothing!

What a waste of money.. What the hell is that much Vram good for on a consumer GPU that is meant to play games?

You act like NVIDIA hasn't sold Titan the past 2 gens for $1000. Also, 980Ti is available, just like a 1080Ti will be as well.

Shhhhh, they don't like to acknowledge this.

Now we're heading toward 16nm with DX12. I think it goes without saying that AMD will improve the front end of its next gen architecture. When I couple this with the gains we're witnessing under DX12, with GCN, then I can't help but get the idea that Greenland is going to surprise a heck of a lot of people (remember what is limiting Fiji's performance and I think you'll sort of see where I'm going with this). Fiji was simply a maxed out Hawaii/Grenada whereas Greenland is a new ISA. That means the entire architecture has been reworked. From the Front end to the Compute Units, Caches etc.

It seems to me that Pascal is like Maxwell 3.0. Sort of like AMD going from GCN 1.1 to GCN 1.2. Arctic Islands is not GCN 1.3... it has undergone far too many changes that AMD has dubbed it Post GCN (it's a new ISA after-all). On a side note, I think that nVIDIAs post Maxwell architecture will be Volta.

THIS.

When Nvidia announce Pascal after volta, it become pretty clear that Pascal is just a Maxwell with HBM. There is no reason for Nvidia to anounce a product(Volta) before the one they are going to release first (Pascal) unless it is a refresh. You guys can take a look at Haswell Refresh, Kabylake. Pretty much the same thing.

At the time Nvidia announce Pascal, Nvidia must be been thinking the result of HBM, node changes is enough to give Maxwell a significant performance gain, ontop of that with AMD remain uncompetitive at the time. That means Nvidia at that time think Pascal will be enough to complete with AMD.

A lot of people seems disagree with me that Maxwell is memory bottlenecked back then when 980 launched. IMO Maxwell could have been much faster if not for their narrow memory bus, take a look at GTX 960 vs GTX950, the latter have 25% shader cut off, slightly lower clockrates and GDDR5 being artificially limited to 6.6GHz, with all that 950 still is almost as fast as 960. 980Ti shares the same thing too, it has a couple of shader cut off, but it is still as fast as a fully enabled TITAN X. If GTX970 didnt have their memory bus cut off, it would have been as fast as 980 too.

Now imaging if all that memory bottleneck is being lift off by using HBM, as well as the power saving from HBM that allows the GPU to clock much higher. (may be 1.5GHz). So will Pascal be fast enough for 1 generation? More than enough, there is no need to bring new architecture Volta out on the table now on a immature 16nm node.

Nvidia mentioned Volta as least as far back as GTC 2013 in March of 2013, long before even Maxwell was even released.

I think u got me wrong. May be my poor choice of using words.

I mean there is no reason to announce a product first only to release right after than the one u announce later(pascal).

Did u see AMD announce steamroller b4 piledriver? Same thing that happened in Intel, Haswell refresh was announce later than broadwell,

I'm hoping for better multi-gpu support with DX12/Vulcan titles. I'd like to get a few cards working in tandem. Would be nice to see 4k gaming with all of the settings on Ultra in newer titles biggrin.gif

Fury X has the same or lower TDP than both the 7970 and the 290X. It is stupid to think Fiji hit any "new" limit except for die size of the existing node.

If anything, this argument should be made with the GTX 480 and the 290X.

EDIT: FYI... Same TDP on a larger chip is easier to cool, not harder.

But why? You're comparing:

Gen1 big chip

Gen2 medium chip
Gen2 cut down big chip

Gen3 medium chip
Gen3 big chip

This is four numbers when we actually only changed generations twice - and he used the 780 instead of the 780ti when there was very significant performance difference between the two (25% more smx, IIIRC?)

If you're doing an apples to apples gen comparison with the same tier of chips you'd go 580 to 780ti to 980ti/TitanX and the gain is far greater than 30%

anandtech links because effortless and i don't have much time ATM

http://anandtech.com/bench/product/1444?vs=1441

http://anandtech.com/bench/product/1441?vs=1447

First one had node change, second didn't. The last time we moved to smaller manufacturing process and got architectural improvement, performance increased to over double what it was. This time we're getting that + memory bandwidth is tripling; there's no way we are talking about 1.3x performance here.

While I do agree with you argument about mid range chips, +30-40% performance per year very much is a trend. Due to the slowdown of nodes, you WILL NOT be getting +100% over a Titan X next year.

You'll get a 680/980 style chip. They need something for the year after, and it'll be the 780TI/980TI style chip with that years 30-40% boost, per usual. AMD is going to take the same route, and the logic is simple; make your money on the smaller die that still kicks butt before you're forced to make 600mm^2 monstrosities and sell them for, relatively, petty change.
