Company officials told the journalists that registered memory modules don't overclock that well on the AMD64 platform, and as the Athlon 64 is aimed at enthusiasts, that's a bit of the paradox.
And the same officials claimed that increased performance of the Athlon 64, estimated by some to be 30% greater for 32-bits than competing X86 chips, is probably rather optimistic. The firm also appears to think that it might be harder than expected to clock the Athlon 64 at 2GHz, although of course an Opteron at that speed was released recently. It also confirmed that the difference between the 940 and the 939 pin designs of the future chips are, as first reported by AMD Zone, to disable symmetric multiprocessing on the desktop version. As for future DDR 2 technology, which as we've written before forms the basis of desktop chipsets planned by Intel, that's not likely to give much of a bandwidth boost to Pentium 4 based machines, Corsair reckons. The change apparently is just a way for Intel to differentiate itself from the competition |
That the difference between the 940 and 939 pin CPUs would be only to disable SMP (Symmetric Multiprocessing) is totally contradictory with a previous article made by the Inquirer. I guess time will tell what really are the difference between both versions.
