That's my guess anyway; I could be wrong.
No, it's still 2.8GHz per CPU. All multi-CPU does is increase computation, not the actual frequency. And that's what they're advertising, they're advertising a system that computes at 5.6Ghz, which is false, the system operates at 2.8GHz x 2 CPUs, which each have an independent frequency of 2.8GHz.
I think what they mean to say is flops, not gigahertz. Gigahertz is the frequency per CPU, however, with 2 CPUs, you double the flop rate, but not the actual frequency of the processors. Flop rate is how much data you compute per second. Example, 5Gflop/s, with two CPUs on a motherboard, you double the flop rate, but each processor still runs at 2.8GHz.
So they're wrong that it's 2.8GHz x 2 = 5.6Ghz. It should read something like...
5Gflop/s x 2 @ 2.8GHz = 10Gflop/s @ 2.8GHz.
Data computation is doubled, but frequency is not. Hope that makes sense for you.
