IF the clocks and SP counts are correct for Barts,AMD succeeded in "milking out" around 25% increase in performance per SP vs Evergreen line(normalized clock Vs 5850).This is very good achievement and if Barts XT manages to beat 5850 then kudos to them.Looks like that Cayman will be ~1.5x faster than Cypress(1.25x IPC * 1.2x SP increase) ,if it is 1920SP or 2xBarts. Many "ifs" so far
not tessellation from what I've just found... >_>....Originally Posted by informal

You didn't get the memo? 1 hour 'Fugger time' is equal to 12 hours of regular time.
Not tesselation in regards to *what*? And where/what is the thing you just fuond?
Why? Because some of the features specifies a "tessellation unit" in singular?
I very much doubt that AMD didn't improve tessellation performance. I'm of the mind that the "leaked" benchmarks point to what we should see out of Cayman in regards to tessellation performance.
I don't think the problem is the tessellation unit but more than likely there is another bottleneck that they have addressed to improve the performance.

one unit is fine if it can handle it but it in some places it can't so more is better to split the work up with.
The only bottleneck I've seen is that one 5870 isn't accessing memory as fast a two 5770 can.

Or maybe because the CF 5770 has double the setup engine?

Twice the triangle setup rate and two tesselation units vs. one. HD 5870 has faster memory access as those 5770s most of the time are accessing the same information at the same time.... at the same speed. And, ummm, even if the 5770 did magically double usable bandwidth you're looking at two 128-bit controllers using slower memory.
So, yeah, guess I'll just ignore that thing you said earlier about tesselation in 6xxx

one 5770 a stock is 13.6 gigapixel one 5870 at stock 27.2 Two 5770 are equal to one 5870.
The tessellation unit is the only advantage their.
A smaller memory bus isn't necessarily slower, because it's usually shorter then a bigger one.

gigapixels |= triangle rate...
Both 5870 and 5770 can, at best, do 1 tri/clock.
Since they are both clocked at 850mhz they are even.
Except you said 5770CF vs 5870, meaning 5770CF has double the tri/clock of 5870.
