New rumor about ATI Southern Islands

[tajoh111]

hmmm that doesnt sound that good...
more realistic, but a bit dissapointing...
looks like the 6870 will be close to a gtx480, but definitely not faster... might not even match it...

im really dissapointed that barts doesnt reach 5850 performance...
that would have been killer... a 150-200$ 5850...
it looks like the 6000 series will be a mere update, if this positioning is correct.
this looks like it doesnt deserve the 6000 name imo, according to this table it should rather be:

5990
5980

5890
5880

5790
5780

For some reason, I think this is more about pricing than anything. It would seem too screwed up if the 6850 never caught up to the 5870 when there is only a 15 percent between the 5850 and the 5870. It would have to be like only 10% faster and to call that a 6850 would be shameful and misleading.

It would kind of mirror what NV has done with gtx 285 and gtx 275 those and could simply be a super minor update.

But only 10% difference. This could be fake and all but considering the timing of this lineup and the obvious flaws found in some of the benchmarks results, this appears to be more genuine.

The 5870 in some games where ATI is favoured already bests the 480.
Since SI strengthens the weakest areas of 5 series performance and also includes a more efficient 4 shader model (and more of them) with a higher memory amount AND bandwidth (as well as more tesselation modules) then it's not very likely that the 6870 will be anything less than the 480 in the worst case scenario.

Definitely faster.

Who says the 4 D shader rumors are true those. This could simply be 1920 5 d shader like the previous gen which would yield between 10-20% more performance, but even that I think would be too conservative for AMD. However, all AMD needs to do right now to slap NV around is a conservative addition, as their current generation is beating NV pretty bad except for the gtx 460 when you include power consumption. If we look at it from that perspective, the performance falls exactly in line with this chart.


Their is one conflict however with the above chart, If AMD is going to have a 384 bit bus, why would they need ddr clocked at 1.5(6ghz effective) ghz? Thats too much bandwidth for any card.
