JC over The Register's Willamette

JC heeft een interessante posting over het Willamette nieuwsartikel van The Register op z'n site geplakt:

Register put up a very interesting bit here. It's about a surprise Willamette introduction in February of 2000 ("paper launch" in December, chip actually appearing two months later, according to the article). I passed this by despite the fact that a good ten percent (slight exaggeration, but you get the idea) of y'all emailed the URL to me. It just doesn't seem likely, considering the design, to our collective knowledge, hasn't taped out (and if it did, it was likely recently). Takes about a year from tapeout to production. You do the math. However, as I said, I wasn't going to put up a link to it, but I just realized something (thanks to Jocelyn Fournier, I think, for nudging me in this direction). The specint95 score of the P7-1100 shown at that register article is utter crap. If it is really the case that it is that slow, then Willamette will be pretty pathetic for servers, especially if you consider the 1MB on-die L2. The quoted score is 43 at 1100MHz.

By my guesstimations (with the help of idiot from Ace's), an Athlon at 1100MHz would score between 50 and 55 (perhaps subtract a point or two for dropoff from linearity), depending on whether or not you optimize for prefetching. This means that Athlon pastes these alleged Willamette scores in specint. Actually, from the look of it, given Intel's Coppermine presentation at PF, it seems that Coppermine is also faster than Willamette in specint. I didn't check at all with the Winstone score, but as you can see, if Register's data is true, then it isn't really great news for Intel. I don't know about you, but I'll prefer to believe the more reasonable assumption that Willamette will come out in 2000 Q4 (or 2001 Q1) but will be totally rippin' in performance. [break] En later: [/break] Registerama: If you look hard, you'll see that Register has (as of this writing) unpublished that "Willamette 1100MHz" story that caused such a ruckus yesterday (the file is still there, but it is no longer linked to on their page).

Het artikeltje (van 18 oktober) staat nog wel in de archieven, maar is van de frontpage (tot 17 oktober) verwijdert.
