AMD Cayman info (or rumor)

[SKYMTL]

Wow. Although given the reports of >225 W for Cayman XT I can't say I'm surprised.

255 W is also higher than the (claimed) TDP of GTX 480.

TDP does not mean max power consumption.


Remember, AMD lists Max Board Power while NVIDIA uses TDP. Those are two completely different metrics.


MBP = specification which an add-in partner needs to specify their board to handle if they want to mount a specific chip to it. It is very rare that a program will stress a GPU + mem enough to even come close to MBP. It can also be used as the absolute peak power consumption a given board design is meant to handle. Meanwhile, it is possible for GPU + mem power consumption to EXCEED TDP.

Hence why you don't see linear scaling between AMD's MBP figure and NVIDIA's TDP in more reviews' power conumption charts.
