    The answer is yes and no. For any application that is doing massive ammounts of number manipulation on a small and colocated set of data (i.e. cachable) you will see performance at approx 4.7x10^9 operations per second. This is for the most part completely unrealistic since today's data applications usually operate on large quantities of data that are spread out through memory. For the average case, the computer will operate at somewhere over the speed of the Front Side Bus (FSB) which is still running close to the same speed it has been running at for the past 4 years. You will indeed notice a speed increase due to any computations that do not require the use of the FSB, but it will probably only be around 50% faster as opposed to 400% faster. The intuitive reader will note that the jump from a 100MHz to 400MHz processor was also limitted by the FSB and thus did not acheive a 400% increase in speed.

    Hmm.. Well, AMD's Barton core that's supposed to be released in October or so still use a .13 micron die (mostly "just" 512Kb L2 cache and 333Mhz FSB). And I thought that was the core they were going to live on until the Hammer processors. :-/

    Sure, they *could* manage to start manufacturing the Truly Final Non-Hammer Core sometime in mid-2003, but by then the Hammers should be out (?) and I'd definitely go for and AMD Athlon (Clawhammer) 3400+ in Q1 2003. Mwhaha :)

    But they might plan on having .09 micron Athlon XP's and Clawhammer models overlapping each other throughout 2003, although it *seems* unlikely since the Clawhammer (at least the initial models) also use a .13 micron die. Much like if the tech isn't quite there yet for affordable prices.

    I think the P3 pipeline had 10 stages, while the P4 had 20. So the problem with branch predictions are the Pentium 4's problem. ;-)

    But what about the P4's Hyper Pipeline tech that allow it to do 3 pipeline stages per clock cycle? The P4's Branch Prediction Unit (BPU) is also said to be improved by around 30% when compared to the one found in the P3. Perhaps these improvements even things out a bit while still making it easy to achieve high clock speeds?

    Well, for those who didn't get the three operating system line, the original IBM PC came with your choice of three different OSes, MS/DOS 1.0, CPM/86, or something called p-System, some pascal based OS.

    So, when I said two out of three ain't bad, I meant there is no way in hell an anniversary PC would give you a choice of OSes. Microsoft just wouldn't permit it.

    p.s. No, it's not that funny. I have no idea why it's easier to get slightly humorous posts modded up to a 5 but posts with serious thought and hopeful insight in them never get modded up or often get modded down by someone who just doesn't agree with you.

    Whatever, not like it all matters anyway...
