Just to back your point up, here is a snippet from theregister about
Sun's new server chip.  (This is a rumour piece but theregister
usually gets it right!)

    Sun has positioned Niagara-based systems as low-end to midrange
    Xeon server killers. This may sound like a familiar pitch - Sun
    used it with the much delayed UltraSPARC IIIi processor. This time
    around though Sun seems closer to delivering on its promises by
    shipping an 8 core/32 thread chip. It's the most radical multicore
    design to date from a mainstream server processor manufacturer and
    arrives more or less on time.

It goes on later to say "The physical processor has 8 cores and 32
virtual processors" and runs at 1080 MHz.

So fewer GHz but more CPUs is the future according to Sun.
