Mosfets on video cards - question

post #1 of 6
Thread Starter 
I hate to place this question here, however, I do not know where to put it.

Does anyone know how many mosfets are on the Sapphire R9 290 [reference] video card, and how many are used by the GPU?

Thank you in advance.

5+1+1 phase 5 Phase Core/ 1 Phase Memory/ 1 Phase PLL

IR6894 / IR6811 DirectFET mosfets (these http://www.irf.com/whats-new/nr110201.html)

Coiltronics chokes/inductors (Cooper bussman Coiltronics 1007R3).
