POWER7 has a max clock of 4.25 GHz according to that reference. Anyhow, clock rate in this case is irrelevant. Look at the instruction latencies. I don't have these handy, but I'd bet $50 at at the chance of winning $10 that decimal floating point instructions (at least the divide) are slower than the IEEE754 ones. These chips are also ridiculously expensive, so probably not the best benchmark. |
