The TDP.
Posted 09-17-09 at 01:42 PM by sLowEnd
TDP stands for "Thermal Design Power" and it is intended to be a guideline for how effective a heatsink should be to adequately cool the object.
It gives a very rough idea of what the heat dissipation is, but it certainly isn't accurate.
For example, a Q8200 and a Phenom 9750 are both 95W TDP.
Do they consume the same amount of power or produce the same amount of heat?
No. The Phenom clearly consumes more power and produce more heat.
I also don't get why people complain about the TDP of the Phenom II X4 965BE being higher than the TDP of the Phenom II X4 955BE.
TDP rises when you overclock, so buying a 955BE and then overclocking it to 965BE levels doesn't necesasrily net you a cooler chip.
Seriously, sometimes I think that people overreact to TDP ratings.
