The guys from Bit Tech had a chat with AMD and heard the low-end RV710 and mainstream RV730 GPUs will be available in September - these cards will offer competition to NVIDIA's GeForce 9500 GT and GeForce 9800 GT. The reporter also heard AMD is on schedule to deliver its first 45nm processors in the fourth quarter of this year:
We also asked about how AMD was going to compete with Nehalem, and in true PR fashion the AMD guys were pumping it up because "[it] will have the leading multi-GPU platform at the time of launch thanks to Intel's X58 chipset supporting CrossFireX". That's not to say Nvidia might have something else up its sleeve by then because it also has an X58+NF200 SLI solution too.
We were told that AMD will absolutely have its 45nm products available in Q4, and clocks speeds are apparently "fast" although we've heard that one before. We'll cautiously wait for actual products, please - after all, we've already seen Nehalem working...
Not only has the cache been increased substantially, but AMD claimed the memory controller performance has been tightened up and even though it's still on the current K10 architecture, it went further to say that there has been plenty of improvements and optimisations but didn't go as far as to specifically comment on what they were.
