A little secret popped out with the release of AMD's FirePro W7100, a new family of GPU that goes by the name of Tonga, which is very likely to replace the aging Tahiti chip that has been used since the HD 7900 series.  The stats that The Tech Report saw show interesting changes from Tahiti including a reduction of the memory interface to 256-bit which is in line with NVIDIA's current offerings.  The number of stream processors might be reduced to 1792 from 2048 but that is based on the W7100 and it the GPUs may be released with the full 32 GCN compute units.  Many other features have seen increases, the number of Asynchronous Compute Engines goes from 2 to 8, the number of rasterized triangles per clock doubles to 4 and it adds support for the new TrueAudio DSP and CrossFire XDMA.

"The bottom line is that Tonga joins the Hawaii (Radeon R9 290X) and Bonaire (R7 260X) chips as the only members of AMD' s GCN 1.1 series of graphics processors. Tonga looks to be a mid-sized GPU and is expected to supplant the venerable Tahiti chip used in everything from the original Radeon HD 7970 to the current Radeon R9 280."

I expect there will Tonga (cut down) and Tonga XT (full chip)?

I wonder how much more of a premium the AIB's will charge for versions of this card that will have more than the rumored 2GB of VRAM. I've thought that the 384 was a bit overkill for the 7900 series, but that 3GB of VRAM sure has come in handy for some of my games.

It will be good to have TrueAudio, CrossFire XDMA, and other features across the whole line-up. I am curious what they are going to name it though. Will it be just re-badged as a 280x even though it is a newer design compared to the current 280x?

Next question is, will this new Tonga GPU support AMD's upcoming "freesync" technology?
