ATI cuts 6950 allocation

[vorticalspace]

do we know the REAL reason why the launch was delayed ?
just so happened to come after 580's launch, thats without the 570 in the frame
if the 6970 is marginally above 570 im gonna be ****** off
surely they are not going to have nothing to compete with nvidias top gun ? ( single gpu ) a card that apparently is a year late from what it should have been

Well if that is the case(unlikely), AMD have thrown Nvidia a massive life line

 

[JediFragger]

To be fair to AMD, they did state some time back that the 6*** series of cards wouldn't be a big jump up in performance - More about the efficiency

 

[Mr Krugga]

the thing i keep asking myself is
why would magicroundabout and raven both say what they said about info from their sources

Why would I claim to use IE?

Gibbo and ocuk get a mention!

There goes Gibbo's right to first stocks at Radeon 7000 launch

i used google images here, if anybody can find better ones?

You better send me that picture you got rid of, email in Trust.


And something for you guys to consider, these are scores from various benchmark done by review sites at the launch of GTX580. Tell me how would AMD fit their 6950 and most importantly, 6970 into that table if said GTX580 is on average 45% faster than HD6870 and 35% faster than HD5870?

Now you tell us

Personally I don't really care about efficiency. I just buy whatever is fastest. If the 6970 beats GTX580 I will get one, if not I will wait until the next round.

Interesting post
What are you implying?

Radeon 6900s will suck, I am hungry.

i so hope your wrong

This makes no sense.

If the 6970 doesn't beat the GTX 580 then why not get a 580?

Guys i would appreciate some advice - the last gfx card i bought was a 8800GTX, but think ill be picking up a 6970 this week. What is the minimum PSU you think will be needed to run this? i know we dont have full specs yet, but in keeping with, say the 5870 or 6870, what will be the minimum required??

i have a HX520 and am thinking this should be more than enough considered it ran a power hungry 8800gtx!!

I ran a 5870 with an i7 @ 4GHz using an HX520. A 6870 should require about the same power as a 5870 so you should be ok with what you have. The HX520 is better than most 600 to 700W PSU's anyway.

I'm going to go with theory that we will see -

Caymen XT (6970)
1536 Shader Processors (effective 1920 SP with 5D units performance)
384 (4D) Shader units

Caymen Pro (6950)
1280 Shader Processors (effective 1600 SP with 5D units performance)
320 (4D) Shader Units

People will look at the 1536 SP and be like " WTF???" then look at the benchmarks and be like " WTF???"

LOL

No, I'm definitely hungry.

And I won't comment on 6970's performance but it's definitely not going to be slower than GTX580 by more than 5% bar heavy tessellated applications like Unigine Heaven. I don't rule out it beating GTX580's ass either.

HD6970 isn't a core with 20% more shaders than HD6950, it's the latter that is a crop of a bigger crop. I very much doubt that 6970 has 120% of Cayman Pro's shaders. It would rather be 80% of Cayman XT's shaders for Pro.

The 6870 has 1120 SP isn't this to close to 6950?

I'd subscribe to that

Oh, and don't forget the price

A 1920SP card should beat Fermi, but I thank a 1536SP would struggle. Even if ATI pull all of the optimasation bunnies out of the hat I cannot see a 1535SP card with "1920 virtual" shaders beating the GTX580. Making the physical shader count less than 5800 sounds like a bad move to me if true.

Even if a 1536SP card matches or beats Fermi ATI have still dropped a clanger. That would just prove what a monster Cayman could have been with 1920.

I am hoping for a 1920SP monster. I am now expecting and 1536SP damp squid.

Yes but the 6870 is 5D shader units so its more like 1120 compared to 1600.

The next step up from that would put the 6950 at 1408 SP with an effective performance of 1760 SP. Is that too close to the 6970 or just about right?
The 6850 is 85% of the 6870, and with my original guess the 6950 would be 84% of the 6970.


This is all just assuming the 4D units will be as effective as the 5D units, the only reason to change it if that wasent the case would be for the 6970's to be a testbed for the 28nm generation that follows...which they pretty much are so what im saying is just pure guesstimation.

I'd subscribe to that

No!!! I'll shut up about it now haha

 

[easyrider]

So the 5870 has what D shader units?

 

[Gerard]

I really don't see the 6970 beating the 580 for the simple fact that amd dropped that strategy several years ago and instead focused on dual gpu cards for the high end.

All we've seen so far is rumour, and its almost a certainty that if the 6970 is indeed slower than the 580, people will be acting like it was an amd publically stated fact that 6970 would be he faster card.

Launch day should bring some drama either way..

 

[Fx-Overlord]

So the 5870 has what D shader units?

5D. Four simple shaders and a complex shader.

Cayman : 4D "medium" shaders. Complex operators such as transcendentals will take up 3 of 4 of the shaders rather than the one complex shader in the Cypress case.
