If the die size is big enough to take the IO of a 512 bit bus, it would be foolish not to put it on. Thats not to say it will all be used, it could be some sort of redundancy. 8 64bit chunks tied to 64 rops, fuse 2 64 bit chunks and end up 6 and 48 rops as has been rumoured (I'm assuming rops are tied to the memory bus here). As to the number of stream processors, maybe they've gone for smaller less complex SPs so 4096 might be possible.

it will added efficiency thing

Look at Nvidia 1536 can beat 2048 Tahiti
so VI will be better at efficiency

2560 - 2880 ALU or same as Titan but better performance overall

it seems small jump on ALU number but as this is new GCN 2.0
the efficiency and utilization is the target

I would love for AMD to grow a pair and go all out with a massive 500mm2 die, but its just not gonna happen. They have no high margin HPC market to offset the horrible yields and related $$, something NV can do to their advantage.

It would take a very very brave AMD engineering team to even suggest going down that route.

RS you talk as of 1.25 - 1.3 Ghz is the exclusive preserve of GK110. every high end and mid range TSMC 28nm chip from Nvidia and AMD has hit those clocks at max OC. Tahiti, Pitcairn, GK104, GK110 have all shown they can hit those clocks with voltage control and good cooling . so why is Hawaii not supposed to be able to do it ?

A question to you - why do you always look at the past ? The past is not always the predictor of the future. If thats the case AMD would never have been able to create Athlon K7 and Athlon 64 K8. You are adamant in your views that Nvidia is unbeatable and this after owning an AMD card. If you don't have faith in AMD atleast lets wait till the results come out.

I think your missing his point. The more you build and hype this chip up, the more your setting yourself up for a huge disappointment. you are not leaving much room to be impressed. At the very best case, it might somehow meet these extraordinary expectations. But the more that is piled on, the chances become more and more slim.

What he is saying is that a very monumental achievement could be loosing its chance to be appreciated. That there is much more harm in building up huge hype in god like specs than just having a very modest outlook. A minimalist outlook is best suited.

The chip is coming out regardless of our expectations. The lesser your hyped vision, the greater the impression. It may very well be extraordinary and when it launches its all the better. Having a modest bar set is like setting the stage to be blown away. You see, the more you build it up before hand the less grand it can be.

given the 21 month gap between Tahiti and Hawaii I feel matching Titan is the minimum AMD needs to do. AMD is launching 8 months after Titan and 5 months after GTX 780. AMD knows a fully enabled GTX 785 is round the corner. In fact if AMD wants to be in a good position they need to edge out Titan and match GTX 785. that would mean Nvidia does not own the flagship GPU crown. This would allow AMD to increase their GPU market share at the high end and increase profit margins. This will bode well for AMD's Firepro products too.

whats first the 9990 at $999?
then the 9970 at $550-$650
then the 9950 at $400 around Christmas.

I don't think they are going to release anything super until may of 2014 anyway
how super, well it will beat an nvidea by 4% weeeeee

Overall they spent all their time on little boxes and not on pc.
It seems that the big problem with pc is not the computer but how much they can rape for each part. mb, video, audio, case, ps are all too high.
its surprising with amd all but dead on the cpu front, intel isn't $1000 for a I7

Leadbox I love that black out, now if you can sell that to the manufactures we will have it made

Anyone think that Nvidia will put that empty spot for an 8 pin power connector to good use with the inevitable up and coming bad boy?

Bet your rubbing your hands together in anticipation aren't you?Heck i know such a card is out of my price range and it even excites me.

Of course I am. I'm coming into slow season at work and am going to have a few months of extra pc gaming time. Maybe if you're lucky I'll hook you up with a "cheap" 780

I never said 9970 will not hit 1.25-1.3Ghz. What I am saying is I don't think AMD will clock their card at only 0.95-1Ghz. Looking at 680 vs. 7970, AMD needs a lot more shaders to beat a 680. Since I doubt AMD will make a 480mm2 die, they may choose to compensate for various TMU/ROP/SP units with higher clocks. I think AMD will go with a 430-440mm2 die at higher clocks than 480mm2 die at < 1Ghz. Because of that I do not anticipate the same overclocking as the 780.

I am really looking forward once the specs are confirmed and BM's are out to see who was the most accurate on predictions concerning die size, other specs, performance and will be revisiting the threads going back a couple months.

My crazy spin.

AMD being a company of reusing technologies took the work it has been doing with/for MS and Sony; thus, marring a 7970 with its 32 compute units to half a PS4/xONE jaguar (quad core x86 with 4 compute units) under hUMA. The PS4/xONE chip would have 128bit bus going to 1gb memory and the 7970 the other 384bit 3gb, making a 512bit of memory interface. Further driver tricks were used to speed up/avoid/offload processing from the CPU.

I fail to see how beating nvidia is somthing you need to be sarcastic about, 4% is still 4% more performance.

Intel DOES have a 1000$ I7, its called the 3970X...........

AMD needs slightly more shaders to match a GK104. if you compare at same clocks HD 7970 > HD 7950 >= GTX 770. if you have doubts bench a HD 7950 at 1.3 Ghz against a GTX 770 at 1.3 Ghz. the HD 7950 on average wins more games and with bigger margins. so worst case 1792 GCN 1.0 shaders = GK104.

you think GCN 2.0 has no efficiency improvements. also Tahiti was a bottlenecked design having the same front end(2 ACE, 2 geometry engine and 2 raster engines) and back end (32 ROPs )as Pitcairn but with 60% more shaders. Doubling the front end and increasing the ROPs to 48 would improve perf/sp.

RS AMD has gone big die at 460 - 480 sq mm. you will know by mid Oct. :biggrin:

The wait is getting painful now. It's frustratingly close and there is next to zero concrete information floating around. Bring me Hawaii, bring me fully unlocked GK110. Stop milking the clock!!!!

That is only 7 days since you made the thread. 38 to go - seem like a lot of pain ahead...

AMD needs a firmer grip on power consumption as it's die sizes grow. I just don't see how AMD will keep power consumption down with a 430-440mm^2 die size unless they have significantly overhauled GCN. Tahiti is 66% bigger than Pitcairn, yet power consumption with the 7970GE is anywhere from 77% to 125% more at peak and maximum depending on the 7970GE card in question ( http://www.techpowerup.com/reviews/Gigabyte/HD_7970_SOC/26.html ). At 430 mm^2, that is 22% bigger than Tahiti, and if scaling continues to be proportionally higher watt/mm^2, then we are looking at power consumption levels higher than all the initial gtx480's - ouch.

Compare Gk104 to GK110.

:awe: Most certainly close to it imo.

Titan was such a massive scam and I doubt anyone is even buying them any more now, unless it is to add to an existing setup for additional cards in SLI. Nvidia pulled a huge bait and switch. After so long without putting out a big die on 28nm for Geforce, they drop Titan making people think Titan would be it, then they drop 780 using GK110 a few months later for $350 less and almost the same performance...

Glad I managed to dump mine and get the Classified 780s before the new AMD card comes out. Titan is going to be worth half its MSRP on the used market in a short while. I wonder if they will try the same boondoggle again on 20nm.

Looking forward to seeing what AMD can do with a Titan killer for less money and how it shakes things up with heavy Battlefield 4 marketing involvement and bundles.

Forums will be ablaze no doubt. ()

Agree. I don't know why Nvidia didn't let the AIBs just 'go to town' with Titan and make custom PCBs and thrown the voltage/power limitations out the window. That would have made the extra price more justified, and actually given the Titan something tangible over the 780s.

I guess spending $999 on any PC graphics card at the minute is silly, considering you have been, and will be playing console ports 90% of the time. Next week I'm buying either a GTX670 or a 7950 for around £160 and maybe a year after the next gen consoles have been around, I'll pick up a card that runs the NEW generation of shitty console to PC ports 2x faster than the Titan or any current "top end" card, probably for pennies.

The next generation consoles and games will effect us majorly,look at BF4 for example,there is graphs popping around suggesting your idea of a gtx670 over a 7950 is a bad idea,1200p with no AA in that game and its using 2gb of vram and the game suggests 3gb.

Doubting Titan performance with 6gb vram is gonna be pennies,perhaps it will sit in the $349 range 2 years from now but don't quote me on that.
