6800 series slides

uh? 5 series has inferior AF (in actuality) to nVidia (tho can be mitigated somewhat by disabling cat AI) - the fixed version looks to be the same as the current 400 series without examining it in detail.
 
Apart from an apparently 'improved' picture quality, this looks disappointing. Was hoping that the 6850 would at least be 5%-10% than a 5850, doesn't look like it if the 6870 is going up against a 460.
 
It does just seem as though Barts is just a scaled down but with a better tessellation unit, higher clock speed + some other inconsequential improvements version of Cypress. Although I was reading on B3D that there is indeed a chip with 4-way VLIW units that may well be Cayman. The 6000 series is going to be a bit of a mess isn't it? You've got your 6700 series which is just a 5700 series card, then there's your 6800 series card which is something of an improvement over that performance wise and there are a few extra features in there, too, but still fails to deliver on its name. Then you got your 6900 series which is a big ****er with basically a generational gap between itself and the 6800 series. How confusing. :D

I don't really see how you can say it's poor, at Tessellation factors up to 10 you're getting double the performance of the 5870 and considering this is Tessellation factor 9 how much smaller do you want the polygons to be?

Sure Fermi might be faster at really extreme levels of Tessellation, but it won't actually make a difference to model quality.

Then I would suggest not going AMD again!
I take it you haven't had any SLI issues to report... :rolleyes:

What's with the :rolleyes:?

Crossfire scaling was, (is) all over the place. Hit and miss with each game and each driver revision.

SLI is far more predicable and offers far more control in the cp over ati.
I can safely say I've had less problems with my current setup with surround turned on than 5870 cfx on a single display.

Should ati release a 5870/480 successor with 2gigs or more of ram I will be interested, however. Very easy to go over 1gb even at 19x12 w/ 8x aa. Let alone 60x12.

THe rumours have been going mental, it will be incredibly surprising if the 6870/50 don't have exactly the same shader setup as the 6970, and the chances of the 6870 getting 35% improved efficiency, with the same amount of rops, less TMU's without different shaders is, well, theres so little chance its probably rubbish.

Again the 6770 "info" is nothing but rumours.

Ask yourself this, with 35% better efficiency meaning they could make a 5770 in the 6 series shaders with a 20% smaller core, meaning 20% more profit at the same cost, would you really continue making the "old" more expensive version that will make you less money? 98% of the R&D goes on the 6970, the 6950 is literally a fused off part, no extra R&D there at all.

The 6870 will be not much more than a minor change to the 6970, cut off some simd's, some rops, some tmu's, same ratio's, same core logic, it takes 1/1000th of the work to make as the 6970 does. The 6770 would be nothing more than a further shrink, it can only increase profits, or if they want improve performance while keeping the same die size meaning its more competitive and can be sold for a higher cost.

THe idea they won't replace the 5770 is just ludicrous, more profit, better core, more features ridiculously easy to do, higher yields and cores per wafer. Or stick with something less profitable?

The ONLY thing that has been taken as a hint theres no "real" 6770 is the fact its not due this year. Remember the 5770 was the 2nd tier AMD core in the 5xxx range, the 5670 came later. In the 6xxx range the 6770 is now the 3rd tier core, it will also come later than the higher end stuff, the 6770 is no longer the upper midrange, its the lower midrange. THe ONLY info direct from AMD is in several conversations being told the ENTIRE range is being replaced top to bottom.

I really don't know why people talk about Nvidia with better AF, literally, its marginally better, in game, I really can't tell the difference between the teeny tiny lines way in the distance. AS for shimmering, you fairly frequently talk about seeing shimmering, and its ALWAYS from the Nvidia camp. They've had issues with shimmering effects for years, and years.

Because there is shimmering and it's very annoying/distracting when you know it's there.

I think this graph tells us a lot of what's going to be in store.

6970 will be slower than 5970 only just. And that's a single gpu card.:eek:
It looks like the performance will be 6850 x2.
1920sp anyone? 2gb maybe even with fast ddr5 or 384 bit bus.
Looks like 6990 will be two downclocked 6950?
Future looks bright. Just hope games catch up.

Hoping the 6870 will be a good bump up from the trusty 48701gb anyway. I have skipped a generation and been holding off for these. Maybe even a 6850 if they are good and go crossfire later. . .
