It totally matched the 580 in anything remotely new at the time. And was LESS than half the size of the 580 die.Except it didn't, it was between the 570 and 580 in performance. The 660ti was a little faster than the 580, but was based on the GK104. Expecting a two tier jump in performance at this price range was asking a lot, especially as AMD were also focusing on trying to get the power use down as well.
I was only expecting it to be somewhere between 390 and 390x performance wise. IF it's slower than the 970/390 then I will be very disappointed as that isn't even a one tier jump in performance.
And I'm not saying I expected a two tier jump in performance this time. I'm just putting into context why the jump we did get is disappointing. If it's going to take a good, 3rd party cooled 480 to even match a moderately overclocked 970(cheap 970's could boost to 1317Mhz), then we're really only talking a very minor improvement in price/performance over an 18 month old card.
This needed to be at least 390X levels of performance out-the-box to be noteworthy.
