Die size is measured in mm^2, while transistor size is measured in nm.

as it stands now the early XDR2 rumors were simply leverage from AMD to get GDDR5 development back in line with what they wanted it to be

Hopefully they increased the tessellation performance more so than they did from the 5870 to the 6970.

I think this will end up as a mid-high range 28nm chip. I would guess they'll release something with more shaders later in the year.


Maybe not though. A 33% core increase on the 580 would = 680 cuda cores for the 680 lol, but even that seems lower than expected.

you're too caught up on equating number of shaders with overall card performance when you apparently have failed to realize that AMD improved performance by ~15% even with reducing shader count.

Heck, even a 1120 shader 6870 can embarrass a 1440 shader 5850.

the 7900s might have "only" 33% more shaders than the 6900s, but that means very little without knowing the particulars of the GCN architecture. For all we know the new shaders are 25% more effective shader for shader and thus 2048 shaders on the 7970 would be akin to having 2560 Cayman shaders, or 67% more shader power with only 33% more shaders, and that wouldn't even be factoring clockrate advantage.

that's not to say how things will pan out, but its an example of how we simply cannot look at shader count and get too discouraged. Or heck, shader performance might go down with GCN and we might even end up very disappointed, its a possibility, but again, its just an example of why we can't get too caught up in the numbers without knowing the particulars.

I'm not caught up in anything, I'm just giving a thought.

There's no way that a Core 2 Duo can be faster than a Pentium D, it only has the same amount of cores with a much lower clock speed.

Keep in mind it will be a while before nVidia has competitive cards out for this generation, AMD could have a refresh due out by the time nVidia's 6*0s come out.

Right I'm not saying anything as far as performance or anything like that. I just seem to have it in my head that they'll get more SP on the 28nm fab than this.

Nvidia should be releasing lower end gpus first, the 460 was a mid/high end card, but it came out well after the 470/480 and it still had about 33% more cores than the GTX 280.

What if this is a mid/high end card from AMD, with a planned refresh later with more SP's to compete with NVidia's bigger cards?


If Nvidia is trying to get out lower end cards, and AMD is doing the same, than the 460 equivalent of of 6 series will be a 680~ cuda core card.


This just just a thought process, by no means based on anything but thinking and shouldn't be taken as anything but a thought smile.gif

There is no reason to assume this is the case, so why over complicate things? wink.gif
