News-Official AMD R7 & R9 Naming Unveiled

[3DVagabond]

It still does not matter. Clocks determine performance, but power consumption determines clocks. What people do in regard to overclocking and how far they are willing to go (efficiency, mod bios, alternative cooling) is another matter altogether.
The only valid argument would be that Hawaii will have custom models allowed while Titan does not. That is a seizable advantage.

The 780 is actually the current card to beat. Because of the combination of ridiculous pricing and voltage limiting Titan is dead in the water now.

Whilst the titan might be classed as dead for gamers, for people that want cuda processing on the cheap rather than tesla, getting a Titan is worth every penny. To that end the titan is very much a live product with regards to its target audience with is both gamers and people that need cuda processing power. I did have an 7970 but upgraded to a titan because most of my apps were cuda based. Going from a 7970 to a titan might seem insane if you are gaming, but taking into consideration its other uses making the jump was worth it.

 

[boxleitnerb]

Yup, and there are some very strong custom 780s out there. Interestingly, AMDs custom card mostly have a very modest increase in clocks, I don't know why.

And once those six people (figuratively speaking) buy them, then what? High end gaming is enough of a niche market for a consumer product. CUDA is even more of a niche category. CUDA with no support is even smaller numbers yet. Besides how much better performance is Titan than the 780 running CUDA?

Interesting also how people who seem to think CUDA is so important see no value in the OpenCL prowess of GCN.

The way Tahiti got roasted in the press for it's power consumption probably has something to do with that.

Curious...aren't people touting how irrelevant that is given that custom 7970s use so much less power? That can't be the reason imo.

Higher clocks requires more voltage to assure stability. All of that consumes more power. I'm sure *boost helps and powertune does as well, but it still uses appreciably more power than GK104.

*Just to be clear, I'm not a fan of boost or powertune. In real world conditions the cards perform better without them interfering. They're fine for benchmarking though, which is all reviews are.

 

[boxleitnerb]

the overclocking is what I'm trying to account for . If Hawaii beats the titan but is clocked so high that the 780 still surpasses it when both are overclocked, that's all that we'll hear because it's Nvidia (remember the 460 ? compared to the 7970 vs 680 after 12.7 ?) . But if Hawaii beats the Titan at stock with clock closer to that 925 and still be able to clock in the 1300's on air, it would be a clear cut win for AMD then .

How many people overclock, again? The critical reception of the product is based on reviews, and reviews measure stock performance with small added OC tests. The IHV should not take credit for the risk and luck of user-OC. Otherwise the baseline would be Titan@1.2 GHz under water with mod bios. But the fewest people actually do that, so it is moot.

 

[hawtdawg]

go ahead and write it down folks:

28nm
2560 sp's
160 TMU's
40 ROP's
1000/1050 GPU clock
6000 MHZ RAM clock
3 Gig DDR5
384 bit memory bus

Isn't Titan at 551mm^2? With Tahiti at 352mm^2 it looks like they have a lot of room to grow.

It really isn't economically feasible for AMD to produce such a big die, even if they had the technological ability to do so. They don't have the high margin HPC market to fall back on when yields are low. They don't have experience with such huge dies. Nvidia certainly does at this point. Your opinion may differ from mine, but such is life.
Please try not to keep the vision so narrow. There are many elements for a big die to happen.

yet HOF, classified, and lightning 780's are all the rage in these forums and with the 460 all everyone talked about was overclocking headroom ! I don't get it

 

[boxleitnerb]

It depends where you look. AT VC&G is a small small part of the internet community which in turn is a small part in the prospective buyers circle of these cards
OC is relevant only for a small amount of people, it's always been like that.

I really think AMD knows how to make a big die and I do think they have the technological ability. I just don't think they can sell it outside of the enthusiast market unless they really start overhauling the software and marketing their Firepro line. AMD has always made superb hardware... its just the software/drivers that kills the product in the end.

As I've heard, the dual-GPU will be named R9 295X. Thus 290 and 290X will be two Hawaii SKUs. 280X possibly too, although I rather think that one is some form of Tahiti.

Thanks for the news/possible info on the R9 295x. Do you happen to also have a link for this I could read?

Also can you tell me what the X means on the 290x vs the 290?
TIA

 

[boxleitnerb]

Just some guy in another forum. So no guarantee. I don't know myself what the X means.

FWIW (4th Google turned this up)
R9-295 Vesuvius XT Dual-GPU

[wand3r3r]

Tried pasting the specs didn't work. I'll try again.

Alleged 9990 aka R9 / 295 XT

Core Speed 1000 MHz
Architecture Vesuvius XT
Memory 8192 MB
Memory Speed 1500 MHz
Memory Bus 768 Bit
Memory Type GDDR5
Memory Bandwidth 576GB/sec
Technology 28nm
TMUs 288 Texture
Rate 288 GTexel/s
ROPs 96 Pixel Rate
96 GPixel/s Shader
Processing Units 4608
Direct X DX 11.1
Shader 5
Open GL 4.3

4GB/GPU but the same bus as the 7970.

It still blows my mind people care about power consumption on high end cards. I bet these people also buy the latest CPU with a super expensive cooler on it and don't overclock or play games. Most people I know don't care if you can cook a weeks worth of steaks on top of case as long as the card performs better than anything else.

Agree fully, as long as the cooler can dispel the heat nicely. I think it's simply marketing and trying to promote the thing their card excels at which is why NV has been trying to promote it so strongly. In a couple generations when/if the situation is reversed I won't be surprised to see AMD promoting it and NV pretending like it doesn't matter.

 

[Leadbox]

So 2304 SPs
48 ROPs
144TMUs
But 384 bit bus and 4gis memory

It would have to be either 1.5, 3, 6, 12.

Well, to some extent I care. I see no purpose in having +30% power consumption for +15% performance. I overclock, but only as long as efficiency doesn't fall down a pit. Because honestly, the last 10% don't make a difference in playability, they never have. But they certainly make a difference in noise and to a lesser degree in energy costs.
