Citat:Yeah, right. What was again the selling point of AMD gpus? they're cheap.
Ok, their gpus might have performance revalling nvidias, however, they dont outperform them. So the only actual reason why you would consider an AMD gpu is either because you belive in AMD, in which case reason doesn't actually play any role in the decision and we can stop here. The more logical reason is that AMD gpus simply cost less. it might be cool to have a 400$ gpu boasting out the same level of performance as a 6-700$ gpu, but you don't consider that the most money you aren't paying for your rig but for using it.
just an example: A rig with an AMD FX-9370 (highest AMD Cpu I know of) (220W) + R9 295X2 (500W)
leaving out other parts, this currently costs about 1220$ and consumes 720W. I don't know what energy might cost where you live, but here in Germany we're paying 0,30?/Kw, so let's use 0,35$. using your rig every day for, let's say, 6 hours, you use 0,720 Kw/hour, *6 = 4,320 Kw/hour. So your paying about 1,512$ each day. that makes about 550$ a year. So after 3 years, you payed about 300$ more for your power bill than you payed for your rig.
now the same with an Intel I7 5960X and nvidia 980 in dual-sli. (The actual performance of both, cpu and gpu should be a bit (if not much) higher than the AMD rig, but let's assume they had the same performance)
1000$ for cpu (140W) and 1200$ for gpu (350W, 175 each) (600$ each). same calculation as before:
490W = 0,49 Kw/hour * 6 = 2.94Kw. 2.94Kw * 0,35$/Kw = 1,02$/Day. that Makes 371$/year. So after about 7 years you payed your rig in power bill.
let's compare: 1200$ and 550$/year vs 2200$ and 371$/year. after 5 years, you payed 3950$ for the AMD and 4055$ for the intel/nvidia rig.
that still makes a difference of 100$, however, as the AMD righ uses more power, it also produces more heat, what results in higher cost for cooling. So I guess after 5 years the AMD and Intel/nvidia rig costed you the same.
However, if you say money isn't an issue when using a high end rig, I seriously don't know why your actually using an AMD product.
And by the way, looking at this, you may now understand why AMDs color is red, while nvidias color is green.
