Also, Intel is going to release Quad-Core cpu's by the end of the year, which may or may not work in current Mac Pro's, which would give you a total of 8 cores.
Do any of these differences affect latency in audio? I doubt it will much. Software (Drivers, OS and apps) will have much more effect on real world latency. Having more bandwith won't hurt, but if you look at the cost of a Xeon setup vs. A Core 2 setup, it's not really worth to spend the extra money for latency reasons (unless you don't care much about the cost). |
Very interesting , thank you for the reply.
