TWY, < Perhaps because of this?? Using an identical hardware and software setup, none of the Athlon systems throttled at any speed regardless of the punishment we subjected them to. >

Unless those Athlon systems were Palominos, I don't see why Mr. McComas expected any throttling in the first place, given that T-bird doesn't have a thermal diode.

Also, it seems the throttling went away with one of three trivial fixes:

1) Plug a different 1.7 GHz CPU into the motherboard.
2) Plug the CPU which previously demonstrated throttling into a non-Intel motherboard.
3) Realign an air duct on the system case.

My SWAG is that a combination of conservative margins on Intel's motherboards, variances in manufacturing, and some real issues with heat contributed to the results Bert is seeing. If anything, I don't see this as a real issue for 1.7 GHz Pentium 4 CPUs, though it could be a real problem when Intel releases higher clock speeds in the future.

We'll know for sure later on, but that won't stop Bert and Van, the "most intelligent AMDroids in the world," from using a stronger microscope on Intel than AMD.

<If what McComas claims is true, would you expect to see clock throttling playing Quake in one of the normal screen modes as you would normally play that game?>

Funny you should mention that, since I honestly can't tell the difference between 60 FPS and anything higher. And I don't think anyone else can tell the difference, either.

However, there are plenty of people out there who will be using Pentium 4 workstations for hefty-duty applications running 24/7. Surely these people would be the first to notice any instance of throttling, no? I'm sure my coworkers and I would, given that we'll soon be getting 1.7 GHz P4 Linux boxes for running our simulations 24/7.
