I am interested in purchasing a new CPU and have decided to go with the AM2. Can someone please explain the pros and cons of the different wattages listed for the same model CPU. Some are at 89w, 65w, and 35w. Are there performance differences? or is it just energy consumption? Thanks for your help.
The wattages you are quoting are TDP spec values, they represent Thermal Design Power. This is not the power that the CPU requires to run, the actual running power is usually lower.
TDP is a specification that states how much power your cooling solution must be able to dissipate under the highest load/worst case condition. AMD defines this as the absolute maximum.
In general, the lower the TDP value the cooler the processor will be when under maximum load. This is important because for setups, such as home theater PCs, a hot or cool running CPU will require a noisy or quiet fan.
Also, please research around the reviews when AM2 CPUs were released,
if you are looking to get the best performance out of an AM2 CPU setup you need high quality RAM.
JackAnd a 90nm chip...not 65nm.
