Anyone (Scumbria, Hans) care to comment on news that AMD is adding two stages to the Athlon pipeline? I suspect that they have found a good optimization between speed and branch mispredict. If they can truly intro Mustang at 1.4 Ghz and 2nd gen Athlon at 1.5 Ghz using the new core, but with their 0.18u process, I will be very relieved. I was beginning to think that AMD would have to keep one technology generation ahead of Intel in order to maintain clock speed parity. Pravin.

Entertaining excerpts from sharkyextreme.com & later. On the case side, ATX 2.03 specifies four new screw holes on the motherboard tray. These screw holes are needed to mount four screw-in supports that lie under the Pentium 4 processor. These four supports are to hold up the reference Pentium 4 heat sink, which we will talk more about later in the article. There are no cases we know of available today that meet the ATX 2.03 specifications, so we suggest you hold off on buying that $200 super cooling case if you think you might ever get a Pentium 4. Don't fret though, we do expect that you will be able to manually drill the four holes into an old case in order to mount a Pentium 4 without having to buy a whole new case. . . . On the heat sink side, Intel has designed a monster 450g (about one pound) heat sink with a copper base and aluminum fins. This bad-boy feels more than twice as heavy as any socket heat sink we've seen other than what ships with Apple's G4s. This heat sink is designed to provide enough cooling for a Pentium 4 in a case with about 40CFM of airflow. An 80mm fan plus a power supply fan are usually enough to provide this much flow. The copper is necessary to deal with the increased thermal density of the Pentium 4 over previous Intel processors. The move to a .13 micron process will make cooling even more difficult. Looks like the brick-like heatsinks that come with the gigamine are the wave of the future. What did Paul used to say about not needing a fan? I think that was before my time. Cheers, Dan.

Jim Re...<<<<<Doesn't sound like the P4 is built with the hobbyist/gamer in mind...if he is on a budget. sharkyextreme.com <<<<<< Jim, it looks like this guy isn't exactly a great visionary or planner. <<<<. But we have to admit, after receiving AMD's PR spiel on why x86-64 was so wonderful, we scratched our heads for quite awhile wondering why the heck they were even bothering. The thing that made us question AMD's thinking is that AMD's primary markets are low-end mobile, low-end desktop and enthusiast. All the gee whiz advantages of 64-bit computing don't make a hair's breadth of difference to those markets. <<<<< Maybe Scumbia would know better than me but isn't it quite likely speed enhancements in future chips could come easier by doing multi cores on a chip, rather than gimmicks like the double clocked ALU P4. In other words,other than shrinks, because it is getting harder and harder to speed up or add pipelines, ten yrs from now, with 32 or 64 bit computers, most new desktops could have multicore designs; and does a P4 have a chance of beating a 2 or 4 core chip? The Hammer, while being aimed initially at the server market, could actually be AMD's stealth high end desktop chip; actually made for it's speed and IPC power rather than servers. The fact that it could be a great low end server would be an added bonus, rather than it's main function.
