It's been a while since we've seen any truly new graphics architectures from ATI or NVIDIA. G7x and R5xx GPUs have had quite a long lifespan, dating back to almost 12 months ago for ATI and 15 months for NVIDIA. When you consider that the G7x architecture is really just a refinement of NV4x (similar to how R4xx was a refinement of R3xx), we could even say that NVIDIA's current architecture is almost 2 1/2 years old! That's practically an eternity in the world of GPUs, where for a while we were seeing new architectures every 18 months or less. Things seem to have settled down a bit in terms of architecture progression, but the war for the fastest GPU(s) certainly hasn't tapered off.
