thanks for the reply...do you mean each 'thread' is running at 2.66? so 24 threads at 2.66 = 63.84
Or do you mean each 'core' is running at 2.66? so 12 cores at 2.66 = 31.92
Neither one is correct. Clock speeds of each core or thread do not get added together. Each core runs a separate process at the 2.66 clock speed. Take for instance a bucket renderer. If you have 12 cores available without hyper-threading, each core will run a separate bucket at the 2.66 clock speed. With hyper-threading, it will run 24 buckets at the same time. This speeds up the rendering considerably due to parallelism, but each core available still only runs at the 2.66 clock speed.
