With a second party like Anandtech providing power values that show a reference 4890 @1Ghz taking less power than a 285, I beg to differ about this big increase.
Something has to be FUBARed in between the 2 levels.
Well that one's obvious! :P
I meant the difference AFTER considering the normal 4870/90/280 consumptions, looks like this card might have problems later on in its lifespan.
W1zzard, can you check the power consumption values again?
At that usage with TWO 6-pins, it has officially exceeded the PCIe spec. Which is not possible for any card that wants certification.
You forgot 100 120 130 150, and 9800GTX+ 9800GTX 9800GT 9600GT 9600GSO 9500GT 9400GS
Catch is nVidia has MULTIPLE model ranges that they continue making cards for and support. :nutkick:
A good 120mm rear fan and 90nm side panel fans do more than the blower vs fan choice, IMHO.
The Sapphire fan version still blows it out of the vent, just not at a RPM that high.
Over-desperate fans (no, not the mechanical variety)? :laugh:
The 4830->90 all have better-than-good cooling compared to the previous generation 8800Ultra/2900XT. The non-blower non-reference versions (Sapphire 4870 1GB, Powercolor etc) are even better, but not that effective for Crossfire.
Way too closely matched in performance. Just get the cheaper one, aka the 4890 (for now)
90+% of the tests have either card tied or 1-2 fps differences are present. In terms of power one uses a lot more in load (PSU considerations) and the other idle (manual downclock using tools are a "hassle"...
