Win: "My favorite Intel marchitecture revelation was about the "vortex" database, which, on the P4, uses 4x the memory bandwidth for negligible performance gain:" Throughout the entire piece it's difficult to escape one fundamental underlying thought, that being, that the P4 is currently spinning its wheels in the mud!!!

Win...an update to McComas's piece: inqst.com Update: Intel’s Thermal Design Guide has revealed that the absolute maximum power dissipation of the 1.5GHz P4 is actually 72.9 watts. This is 33% higher than the published system design specification, and essentially identical to the 1.33 GHz Athlon. In order to prevent the CPU from exceeding 54.7 watt, thermal throttling is used. 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. This effectively turns your 1.5GHz processor into a 750MHz processor – just at the moment you demand peak performance. On the other hand, you will probably still be able to check your email at 1.5GHz. This scheme is described on page 23 of Intel’s P4 Thermal Design Guide. Commentary is already floating around the web that perhaps Intel feels guilty about selling 750MHz CPUs in 1.5GHz clothing, and thus has decided to cut the price by 50% as well. All in all a very stinging report. It was very funny and a good read. Regards Ed P.
