AMD: Southern Islands (7*** series) Speculation/ Rumour Thread

AMD in deep mess. How do they dare to put this crap at 1000$?

Also, the other cards show lower performance than corresponding NV products

Turn the page on their site.. they had 4 games with no scaling on their long list. ( Diablo3, Batman AC and AC3 ) ... So they have do a second performance list ..

+ they start their performance summary on all resolution at 1280x800 ..

2560x1600 and all res.

Do any of these reviews that just list average FPS actually hold any weight with anyone here anymore? They shouldn't. It's practically a waste of your time reading them...

Guru3d is using Fcat... But Fcat dont tell all anyway.. ( without saying, there's many work on preparation and pretest as the encoding need a good PCI express dual raid setup SSD and results can suffer of glitch ). ( they have even include the prototype driver for Metering on AMD card ).

Edit sorry.. i was think you speak about frametimes. yes i dont know why it dont use minfps.

So an expensive stuttering mess? Good job AMD, good job!

Why release this before the driver is ready? It's already an age late so will 2 more months really make a difference?

Is there market for it? If waiting for better dual gpu drivers was an option then they should drop crossfire as a whole, until it is "ready". I think it wouldn't do them any good though. Perhaps only now they have free resources for driver development, or specifically for 7990, enough of good chips.

That imho isn't quite true. While it may be true the values have little merit in terms of user experience, they tell you what the card _could_ do. Because really nvidia or amd being significantly better or worse in fcat measurements or similar has got nothing to do with hardware (as long as you look single vs. single and dual vs. dual chip). And it doesn't look like you'd have to wait for a new driver to improve things forever neither.
 
Do we even know the reason for these insane micro-stuttering graphs?(never seen anything like them!) Why AMD suffers this with the GCN architecture in particular ?
 
I don't like it because no-one in their right mind would ever use such resolutions with these cards, regardless of which brand does better on low resolutions.
Lower resolution testing is useful for exploring driver CPU efficiency. After all, you can't really do that at higher resolutions.
 
Hasn't this card been chilling out at AMD HQ for a year or so? That there are still driver issues with it is interesting to say the least. Coil whine is something that goes back to the earliest days of beefy video cards (think GeForce FX) and for some reason they keep putting it out there (probably cost related).

In two months those graphs may also be sporting GTX 780 SLI benchmarks in the same price bracket. That'd really take the shine off those results.

Oh no, this is nothing "new" to GCN. MIcrostutter has been around for a long time, arguably it has existed since AFR solutions were first brought forth no matter which vendor you are speaking about.
 
Looking at comparison graphs, the problem's literally orders of magnitude worse on GCN than the equivalent NV setup though. Even with the new "experimental" driver it's far, far worse.

I certainly agree with the comparison between NV and AMD/ATI, my contention was that it's not net-new for GCN. VLIW4 and VLIW5 parts both suffered the same issues.
 
Yeah, definitely, you pay 900-1000 $ and get something designed primarily with cost in mind?! :rolleyes:
Of course the cards are not worth anywhere near that price. The new $1k pricing is just AMD & NV playing new baiting games with us. Though it does sound like Titan is perhaps built better than this 7990. Titan's also undoubtedly cheaper to build.
