While we still don't know if the R700 will be known as the Radeon 48xx, 39xx or some other nomenclature, it seems that the first R700 GPUs actually 'taped out' sometime in December. As with all rumors, we remind you to take the following with a grain of salt:
“[the] R700 is in the process of being fabbed now, or at least its components are. The component thing is a story for another day, the part that matters is that R700 bits are in the oven now and things appear to be going swimmingly, or at least skatingly if you know what Toronto is like in the winter.”
This could mean products on shelves in March if the parts perform well and no flaws are found in the design.
