These are not the P4s that will come into play by the time Doom comes around!
Remember, there'll be 2.8, 3.0, 3.2 and 3.4Ghz, <b>at least</b>, and those will be <b>Prescotts</b>. And, as a matter of fact, <b>we don't know prescott's performance</b>, so we cannot possibly know in advance who is going to be best there... Even in mid-range processors, because the 2.8 and 3.0Ghz will be mid-to-high performance processors in Intel's chain, and will be reasonably priced.
I mean, several reports on the web say that prescott should be around 10% faster per clock when launched. While there are a very few benchmarks around that would seem to indicate that that will not be the case, I tend to dismiss them, mainly because some benchmarks indicated that A64 wasn't going to be that great a processor before launch too.
So think about it: If Intel gets the 3.4Ghz Prescott (equivalent to 3.4+0.34=3.73Ghz Northwood, presumably) and DDR-II and PCI-Express tech by then, it will probably have enough in its hands to fight the rather powerful A64 line with. Anyway, we can't possibly really answer if A64s or P4s will win the performance crown in Doom3, simply because the main contenters aren't in the arena now.
<i><speculation>Personally, I think there is a very high probability that Intel will introduce a 3466Mhz (13x266) Prescott by March, the 29th, just because of Grantsdale and Canterwood. I think that might be the case because of current development status for DDR-II: it is running at 533Mhz OK. This would mean a 1066Mhz FSB, and I don't think that would be too far-fetched. Hopefully, there'll also be a 3200Mhz, 1066Mhz-FSB prescott for a reasonable price... Even if it's not released in march, it is not so far away at all!</speculation></i>
In any case, I'll just wait until mid-year to buy my Doom-3-killing machine... (droooooool....)
And I'll try to get the biggest amount of money so I can get the beefiest rig possible... for it to last some time...
