quote:It is not the future of desktop CPUs. It will not be even a good general-purpose server CPU. It takes a lot of data in, and pushes a lot of data out.
quote:If a branch is encountered, no branch prediction is performed: it would only waste power and transistors. No, the condition on which the branch is based is simply resolved. The CPU doesn't have to guess anymore. The pipeline is not stalled because other threads are switched in while the branch is resolved. So, instead of accelerating the little bit of compute time (10-15%) that there is, the long wait periods (memory latencies, branches) of each thread is overlapped with the compute time of 3 other threads.
