It is an interesting time to bring out a new architecture. There was a time that any short term advantage a custom architecture would have over commodity chips would evaporate in 4 years, less than the depreciation time of the machine. However as the ability to scale commodity machines becomes harder, and they scale in useless ways (like the P4 debacle of focusing on video streaming performance) the economics once again shift to more bespoke machines. And some of these machines understand that memory throughput is just as important as instructions per clock and so you get more general purpose architectures with the memory bandwidth of modern GPUS. That opens up some interesting opportunities for large memory computation spaces.
