AMD Cayman info (or rumor)

[tbone8ty]

Hmm what to do now....

[Particle]

Lol, I see you're sticking to your own guidelines. Btw, the 6970 isn't faster than the 570. They both get their lumps in but it's a wash.

I'll grant you that the definition of "garbage" is debatable, but it seems way outside of realistic discourse for this topic. The 6970 is indeed faster than the 570, so I'm not sure where you're going with that.

Wait for 11.1

[flopper]

lot of people are hired by nvidia to spread fud on forums.

[eric66]

so does 6970 have 1920 sps or not ??

No.

[eric66]

that makes me sad ... very sad .....

[kadozer]

that makes me sad ... very sad .....

There's always next October
There will be another AMD hype speculation thread with wild rumors. I'm convinced AMD will always go for smaller efficient low cost chip strategy forever despite what pre hype rumors will say.

Give it 6 months and you might have the 1920 version out. AMD's 580GTX

As long as Antilles or any dual gpu card exist in the pipeline, I wouldn't put money on it. That goes for future generations.

Not necessarily, all dual cards are based on the single card performance which has it's own market. It's not like they'll stop making single card gpus in the future.

Going 1920sps would mean going outside their small efficient single chip strategy. Since they started the dual gpu card as halo card strategy they've stuck to it. This epic long thread and others like it across the net is proof that it will be wishful thinking for them to deviate.

i think theres room for two more cards, 6980 and 6990; one 1920 and one dual gpu. Jan will be an interesting month thanks to ces.

Will be interesting to see MSRP for Antilles. . I would love to see it happen myself but I wouldn't hold my breath.



Cayman XT $379
Cayman XT refresh with more SPs $470?
Antilles $600?

That what I thought about the gtx 480. In the end, it only got 3 or 4%. It was 14% faster than a 5870 initially and is now maybe a few points better than that.

For driver improvement I will try to be hopeful because I still can't see AMD screwing up this badly, but reality probably says for a single card, maybe 5% at best and that is not going to happen overnight.

AMD obviously wanted this card to be faster. A beefed up cooler, larger chip and 2x the memory(which is faster and more expensive) and likely a more complex PCB to deal with the power and they charge less than the initial prices of a 5870. Considering how little money they made on the 58xx generation, it doesn't make sense for them to decrease their margins.

If antilles can be 600 dollars and have a non reduced spec'ed 6970(I don't care about power, I bought a ax1200 for that and it is still in the box waiting for a new videocard), I would consider buying that.

But as is, I can see even NV competing pretty well and releasing a deal card to deal with antilles.

Something tells me we won't be seeing so much improvements because the card only has 1536 shaders or 384 real shaders even though I want to believe there is more there. Frigg, I bought a ax1200 and a corsair 800d for a new monster videocard and it has been sitting here for the last six months, nothing really warrants its because we haven't really had any real monster cards(the 5970 was close back in the day, but the specs were reduced like crazy).

I think your missing the point? They didnt go with there new architecure because tsmc fooked them around so they had to stick to there current 45nm instead of moving forward and had to cut back the shader count... I say wait for 6990 instead of turning this thread into a flame war..

For the people waiting on drivers to fix the performance, we're still waiting on those for the 2900xt aswell!

These cards are decent enough to make me question purchasing a GTX570, which I wanted really badly up until this morning. Now I'm wondering if the extra memory and maybe a little better performance is worth losing folding power and display capabilites for. Seriously tough decision

You gave your own evidence for driver improvments. How did the GTX 480 go from 15-20% faster than the 5870 at launch to less than that since then? And that's including the fact more Nvidia friendly titles have been released since (e.g. LP2, HAWX2).

Hint: the 5870 got some major boosts

Big difference is that the 2900XT's were quickly shelved/forgotten... they were around only 6 months.

Biggest evidence for driver changes is the fact that 69xx performance ranges everywhere from well above 5870 to only 5870 and occasionally below. Methinks the change from VLIW5->VLIW4 is a big issue, because code has been so heavily optimized for VLIW5 since 4800's AND 5800's have been using it. Makes no sense for 384 SIMD card to be less than 320 SIMD unless there's some issues with compiling vector instructions

See: 5870 release scores/benches (below 4870X2 performance) to today's #'s (just 10-20% below the 480/570 depending on the review you look at).

Also, what display capabilities are you looking for? If you're going single card, there isn't much display wise the 570's can do the 69xx's cant at this point

If you base your purchase on hopes for driver improvement keep in mind one thing, by the time drivers got optimized , new cards got released. And that's a long time to wait, by then it won't matter anymore.

What they did is massively improve the back end of the design ,all on 40nm.Now all they will do is use 28nm to scale up SP count,IMO big time. I can see 2xVLIW4 we have in Cayman,with 28nm version of NI. They are already awfully close to 580GTX with Cayman XT,especially in high resolution new DX11/tessellation heavy games. If AMD and NV effectively double the compute power with next gens,we may have a deja vu next year:AMD having 5-10% less performance with 36-40% smaller die- a clear design efficiency advantage at the same node.

In other words different die same relative performance.

Nvidia = top performing at premium price

AMD single gpu high end = Performance for dollar @+/-10%

2011 = new thread, new year, same speculation

If i am not mistaken at 28nm will be Keplar, new arch. If AMD keeps same arch just doubles shaders it might be different ball game vs Keplar.

That Kepler should now read 2012 since its delayed.
