You're right, I was wrong. It's 30% faster in some games for nearly 3x the cost. My bad.
Compare it to an R9 390 or a GTX 970, both of which start around ~$260-$270 and both perform on par. Compare it to the R9 380X (which costs cheaper by like ~$20). I really don't know why the hell you are comparing it to the GTX 980, which is in a
different performance bracket (high-end always has bad price/performance. not to mention, the GTX 980 have costed ~$400-350 for like a few months now, so less than twice, not nearly three times). I just said that TFLOPS is a horrifically silly number to compare, and that using it is
extremely misleading.
Two of your graphics show the total rig power usage, which while not entirely inaccurate is deceptive at best.
comparing power consumption of different cards under full load while leaving the rest of the system identical is not misleading or deceptive in any way
a higher clock speed
relevant how, exactly? all i care about is end performance
significantly better performance
about ~35% better, which is fair enough i guess. you have to remember that the cheapest R9 380X is ~15% cheaper though. this is some napkin math which I admit might be inaccurate but it would seem like the RX 480 is about ~15-20% better price/performance. which is a decent jump but nothing revolutionary.
regardless the RX 480 has high power consumption in comparison to Pascal and it barely matches Maxwell, multiple reviewer models exceed PCI-E spec, it represents a fairly mild price/performance increase over last gen. the cheapest R9 390 is like $260. you effectively saved $20 for the same performance and lower power consumption.
and then AMD posted on their twitter on how it was going to be similar to the 4870, which outperformed Nvidia's second highest-end card at the time for $100 cheaper. while it turns out it
matches Nvidia's second (technically third but w/e) highest-end card from
last generation while being like a whopping $30 cheaper
It's not a bad card, just overhyped and has some issues with its stock configuration.
