Dale,

"If performance critical applications drive CPU power above its artificially low 54.7 watt limit, the CPU is halted with a 50% duty cycle (alternating 2 microseconds on; 2 microseconds off) until it cools down."

I wonder if CNet and/or ZDnet will have the guts to report this incredible story. If the main line press picks up this story and exposes Intel's P4 clock throttling under heavy load "feature" to their customer base, it could be catastrophic for Intel. Thermal throttling on the P4 will have to occur more and more as Intel raises the core frequency before going to 0.13u, as their thermal limit will be reached more quickly as the clock is increased.

Now, having said all this, I have not seen any reports form hardware sites that have tested the P4 to the effect that they have seen sudden drops in benchmark performance as the chip is pushed. We need experimental results to verify that this indeed happens.

Pravin.
