AMD Radeon R9 M295X

Runs at around 850Mhz given it is fully enabled Tonga.
 

Based on math done via the new 5K iMac having "up to 3.5TF" of performance and doing math.


Or, around 975Mhz if it is only 1792 cores.
 

 

The power usage can't be to high... The Mac Pro with 2 Tahiti chips (850Mhz each) had a PSU of only 480W... The Mac PRo throttled the GPUs down to ~650Mhz with the CPU running ~2.1Ghz while using a total of only ~440W of power.

Let's call that 125W for GPU at that clock, 100W for CPU, and 70-90W for everything else.

Given Tonga is supposed to improve power, running 850Mhz at 125W is not unreasonable.
 

Tonga was made because Apple needed a lower power Tahiti?  :blink:

But Tonga is not that power efficient, the difference between Tonga and Tahiti is very small..

 

Is this R9 M295X in MXM format? MXM-B has 100W limit.
