AMD: The Lies About Power Consumption Start Here

Those familiar with the processor business will be familiar with the term Thermal Design Power (TDP), which refers to the number of watts that a cooling system must dissipate under a maximum real program load. AMD, however, has adopted a different power measurement system to rate its processors.

The new system, dubbed Average CPU Power (ACP), was championed by AMD for the first time with the release of its K10 Phenom family. AMD claims ACP is comparable to TDP measurements in Intel's benchmarks; and is in fact a superior measuring stick for power consumption. ACP is described as being calculated based on an "average" daily use scenario for desktop users or for a server.

Despite AMD's claims that ACP is directly comparable with TDP, many began to have doubts when AMD struggled to raise the speeds on its Phenom processors. This could indicate, among other things, thermal issues due to high power consumption.

My first reaction on reading this article was that it seemed to draw an unwarranted conclusion from little evidence

There could be many reaons for not increasing the speed of a processor, its not all about heat dissapation, what about inter component capacitance for example mongst other things, whilst it does seem there is a flaw in the published paper or a flaw in the measuring methodology, drawing conclusions like the one qouted above is ludicrous.

AMD is losing the market to Intel. I'm not buying AMD, not eve ATI.. this time around I'll probably go NVIDIA as well. Screw AMD. They need to fire the ENTIRE processor development team and start anew.

Fire people for not delivering miracles ?

How strange people seem to get when its other peoples lives they are talking about, what would you say if folks decided you where not producing miracles and laid you off ? :roll:

The constant battle against mother nature and the laws of physics to drive forward technology is never going to be easy and multiple millions are spent on research and development each year, how to optimise those technology gains is what AMD's teams do, they dont and cant change the laws of nature, Intel may currently be ahead in this process of optimising and swapping the architecture around to deliver the goods but the basic laws of nature will always apply.

Market forces will decide whether they want cheap processors that run a little slower of uber expensive faster processors that cost an arm and a leg, Can I suggest we leave the matter in the hands of the consumer ?
