If we knew what ati did with the pipes 16 pipes would be just fine 24 would be better and32 would be overkill . Why would they even bring it out.
Lets say that ati is able to compete with the top of the line g70 with their mid stream model. Which I stated they could yesterday in another post . Now nvidia has to bring out the big dog ultra. Than ati decides what to do with their big dog. I like that ati is doing bring out the mid stream first. that should be interesting if it competes as I said it would.
Most who have been following ATI know that on their first tapout they got 10,500 in PCmark 05. Its not unreasonable to expect 8000 PC mark 05 score now is it. With their mid stream card.
X700 Series are built on 0.11 micron technology, X800 Pro, XT, XT PE & X850 Pro, XT XT PE, Series is built on 0.13 micron low-k dielectric technology, this is apples to oranges.
If you wanna compare the cores you need to compared the R430 and RV410, where the RV410 holds an edge at 420MHZ vs the Core of R430 Radeon X800 XL, Vanilla which is only 400MHZ. Since ATI has no R4xx mainstream/value products on the 0.13 micron low-k process the X700 vs X800 doesn't hold unless you compare the products I specfically mentioned.
Now, since ALL the R5xx parts are going to be 90nm low-k dielectric technology. You would assume that no part will breach 600MHZ in this line as added transistor complexity on an identical process. RV530 hold the record with 600MHZ so far, an a more complex part will not clock higher, quite the opposite actually.
700MHZ is not right in line when all products are 90nm low-k dieletric technology. Last generation was a special case with 2 different manufacturing processes. This new generation has the same process on all 3 lines, enthusiast, mainstream, and value all will use 90nm low-k dielectric process.
There is a good chance I would say for GDDR3 @ 1.4GHZ, if ATI wants to assure a hard launch as Nvidia did, 1.6GHZ GDDR3 would be pushing it. GDDR3 1.8GHZ is well in the super unlikely territory.
It' also extremely unlikely to get 8000 with the mainstream offering RV530, if it can beat Radeon X850 XT PE in 3D Mark 2005, I would be already extremely impressed.
It's also heavily rumored that R520 has 32 Pipelines just that only half work for the most part, so most likely release should see 16 and 24 pipe variants rather then a full working die.
