More than one? Are you talking about amd or including nvidia as well?Yes, 40nm GPUs are an the way (more than one!).
AMD plans to RV775XT confrontation GeForce GTX 285
GeForce GTX 295's mission is based on dual-core dual-card in the form of peak performance to win the throne, and the GeForce GTX 285 is the most natural goal of a single card.
It is reported that, AMD is being carried out on the RV770 to improve and enhance the design, which is the new "RV775XT", but details still unclear, it is estimated that by raising the core, memory-based frequency, and cost-effective to continue the main trump card.
It looks very much like the previous so-called "RV790", but this code is also seen below, there will be no one. In any case, in the heart of the next generation of AMD RV870 available until next year, AMD will certainly have a new action.
On the GeForce GTX 285, the equivalent of GeForce GTX 280 is the enhanced version of the upgrade process, in essence no different, flow remains the 240 processor ,512-bit wide memory and 1GB GDDR3 memory, but because of improved technology, power Turned out to be much lower (said to be 183W), only two six-pin external power supply to meet the interface, eliminating the need for a six-pin and one eight-pin. Of course, the frequency of the new card will definitely be higher.

Last i heard amd's RV740 was going for an A12 revision to fix up minor problems. Power saving on A11 hadnt been so great compared to 55. There is a debate at the moment apparently whether to release a gddr5 version as it might exceed 75W and require a power connector which they don't want to do.
Have not heard about any other specific ati chips. The RV870 has got pushed back a few months apparently to make way for lower margin, probably higher volume products. The TSMC 40nm process has "opened up"(or "melted down" depending on which party you were) cause of everybody cancelling orders.
Both ati and nvidia are no longer constrained to choosing low volume products. In nvidias case this also meant delaying their high end chip and starting 40nm with multiple smaller parts. I guess this has forced their hand into releasing the 55nm GT200 and GX2 to fill time.
Yep, and it doesn't comply with the rearranged RV730-core either. Yet another redesign or is AMD deviating from it's "one size fits all" route?EDIT: Also noticed that according to the number of TMU's, and by going with the current RV770 architecture, the stream processor figure should be 960.
Pretty sure you can't have a shader array length of 14, since those correspond to pixel quads (so needs to be divisible by 4).12*14*5 = 840 and 12*4 = 48
At least it's symmetric, and maybe a better sp/tu ratio, and if it was so easy to change for rv730, it could be..
I doubt that this accounts for much, and given that obviously a major achievement for rv770 was to get higher perf / more units on a given size, I doubt there's a lot of further optimization possible. Also, the use of 1400Mhz memory would mean a return of gddr4 - not saying it's impossible, but all in all I say fake.And regarding die size I guess they are at least cutting the inter connect.
Texture units are bound to SIMD arrays since RV770 again..
