What's "EPG"?

[Manicdan]

@the amd slides benchmark slides.

obviously they did not want to show themselves loosing in any benchmark. FC2 was in one but not the other, probably because its still slower in that game. then again, there were not very many games where nvidia has such an optimization as that game. if you dont see it on the chart, its probably too old, or it didnt win.

[flopper]

well all in all good.
but 6970 aka cayman needs to be much better as I expect it to go almost toe to toe on 5970

[Pantsu]

I'd say 6950 will be maybe 10% faster than 5870 and 6970 maybe 30-40% faster.

I think you are expecting a bit too much.


I keep my bets lower than that.

Hd5870 < Hd6950 - 5 - 10%

< Hd6970 - 25 - 30%




Until we see real numbers it's pretty much priceless.

Its tough to expect much more out of the same process, but keep in mind that AMD used a 30% smaller core and got similar performance... and Cayman is larger than Cypress by a good amount, so I bet its performance is a lot higher than people think

[FlawleZ]

Did we have a naked HD6850 yet?

Nice. Looks like the same size as HD4850.

[FlawleZ]

Which is actually about where the last generation stood.

5850 = 10%+ faster than HD4890
5870 = 30-40%+ faster than HD4890

Of course this varied from game to game.

so much less transistors ... i hope rumors are true ... super low die size .. super low pricing maybe???

From the slide i put above we can estimate cayman performance too.AMD did positioned them accordingly, 5870 is ABOVE 6870.
6970 is looking to be same amount lower than 5970, so it should be a bit faster than 480 but not much.512SP version MAY match it.

25% less silicon and same performance = huge proffit margin making gpu ... nvidia doesnt have anything to counter that .... they need a shrink asap

exactly ... i expect big things from antiles and cayman

[ZoLKoRn]

Leaked results from someone on my forums with HD6870 for 3D06 and Vantage it looking very interesting and i think it real not fake for sure, let to see what about 6870 performance

[Manicdan]

is the 128bit a bug with gpuz database, or is it reading it wrong, or is that the actual bitrate?

[kaktus1907]

why afterburner shows max clock speed 775mhz in that graph? is it 6850 or 6870 ?

More performance with less hardware is very interesting.

[Sn0wm@n]

More performance with less hardware is very interesting.

yep ... + this will allow them more chips per waffer so pricing should still be interesting

they had the same advantage with evergreen and didnt go for perf/$. maybe they will this time, one can only hope.

[Mechanical Man]

How could they when market decided cards were more value than recommended price from AMD.

[Sn0wm@n]

35% less transistors would surely help that dont you think?

and also they had a buggy tsmc node to work with ... and maybe they worked out the kinc now ....

But then again, bart xt is more or less 25% faster clocked than a 5850, which makes up for most of the difference. I doubt the 6970 will have significantly faster clocks because of its size(900mhz max) vs cypress(850). Basically everything has to come from core improvements and added components.

Clocks appear to match polygon counts on both cards(5850 and 6870).

[Lightman]

If anyone wants to compare to stock HD5870 here is my run at the same CPU clocks (bar 2 extra cores which only influence CPU score):

[zerazax]

GPU-Z's 128-bit reading is cause GPU-Z is a database. I'm sure once its updated, it will read it right

You're right that clocks make up a big part of it, but it depends on what other things they put into Cayman. If, as rumored, Cayman has more architectural changes, then we may see even more improvement. Cypress after all was pretty inefficient compared to Juniper (we see that Juniper x 2 often beat Cypress handily, despite having effectively the same numbers)

they had the same advantage with evergreen and didnt go for perf/$. maybe they will this time, one can only hope.

They did. That Fermi was 6 months late and a dissapointment was hardly ATI's fault (TSMC's early 40nm woes didn't help supply either). Simple supply vs. demand at work.

Plus, ATI had no target price point since nothing was there to compete. Since ATI has a target card it wants to attack (the GTX 460), they have a target price point now

agreed, the clockspeed difference makes up alot of the perf difference.

as a whole package its pretty good, but what about when both are overclocked (max typical on stock cooling), that could really close in the gap between them.

i think whats best is the potential this has for mobile chips and fusion products.
when mm2 matter on fusion, this can let them pack in more with good yields.
and for mobile stuff they seem to have a better perf per watt

[ChinStrap]

What concerns me, the 6850 heatsink has 0 heatpipes, while the 6870 heatsink has 3?

[ChinStrap]

From HardwareLuxx:
6850

6870

[Loque]

doesn't deserve the name 6870.. more like 5890.
