that's from the nvidia reviewer guide.
gddr3: 1000 mhz * 128 bit / 8 bit * 2 (ddr3) = 32,000 <-> nvidia 32.0 .. looks right
gddr5: 1700 mhz * 128 bit / 8 bit * 4 (gddr5) = 108,800 <-> nvidia 54.4 .. something wrong here?
The actual frequency is 850mhz, so the formula is:
gddr5: 850 mhz * 128 bit / 8 bit * 4 (gddr5) = 54,400
I have this card. I got it because It uses only ~55watts @ load (i measure it. yes you can measure it even if it does not have a pcie power connector) and performs Good.
Guy's not everyone want's a power sucking monster.
have it paired with a e3200 oc'ed to 3.5ghz, plays everything MAXED out @ 1280x1024
and the whole system draws <150watts @ load. Suck it Power Company!!!!
