Scumbria, >Remember last week when you were trashing Bert McComas?

Looks like you lose again:

P4 1700: Clock speed throttling back under heavy load severely affects Quake 3!


Anand says no to that:

The Pentium 4 1.7GHz on-die thermal diode provided temperature readings close to that of our Athlon 1.33GHz. However, as you will know, the Athlon does not have an on-die thermistor to provide truly accurate core temperature readings but what we can conclude from this is that the Pentium 4 at 1.7GHz is running cooler than the Athlon at 1.33GHz since the latter has a nearly equivalent temperature measured outside of the core which is relatively cool compared to the on-die temperature.

During our tests the Pentium 4 1.7GHz always operated at 1.7GHz and did not fall victim to any clock throttling because of heat. You shouldn’t worry about the Pentium 4 dropping its clock speed because of heat unless you are running the processor without a heatsink/fan installed.
