This generation has support for all recent memory types, including GDDR4. In addition to ring bus, each memory channel now has the granularity of bits, which improves memory efficiency when performing small memory requests. Changes necessary for SM3. ATI has been working for years on a high-performance shader compiler in their driver for their older hardware, so staying with a similar basic design that is compatible offered obvious cost and time savings. At the end of the pipeline, the ATI[…]
