I'm sick of everyone rounding down the performance of a top tier card. Specifically, AMD folks tend to do it most often, they will take something like the gtx780 and say it's only 15% faster than the hd7970, when in fact most reviews show it to be more than 20% faster on average. Hence the reason I chimed in and said 25%. But that is with the 7970GE, not the vanilla 7970. The gtx780 is more than 30% faster than the vanilla 7970.
And also lets keep in mind the 7970GE does not go for $300. There is only one 7970 model on newegg which is under $350 after annoying mail in rebates, but you're still paying $365 upfront and only getting a measly $15 back. Every other model is $399 or more before MIR.
So again with the rounding (to make an argument look better), no it's $300 more for 15% more performance. It's $250-275 more for 30-35% more performance than the 7970.
Well if 6 websites put the 780 at 15% faster at 1080p and 8 websites put the 780 at 15% faster at 1600p, I'm not sure where you have a problem with the numbers being presented.
You're right that sometimes people tend to take the best and worst of differences and try and combine them to show their favorite manufacturer in the best light. It's best for everyone when people are consistent with their arguments.
Regarding price, the cheapest 7970Ghz is
$350AR ($370 before) and the cheapest 780 is
$650. So 15% more performance for an extra $280-300.
There is also a Dual-X 7970 that's 5% slower than the regular Ghz for
$310AR ($330 before). So 20% more performance for an extra $320-340.
The comparisons can continue on down the line and the 7970 will end up looking like a bad value at some point but in the specific comparison being discussed (7970 vs 780), the 780 really is a poor value.
lol cherry picking there.
what is funny is the asinine AMD video talking about how their bundled games are faster on AMD cards when in reality most of the bundled games actually run better on the competing Nvidia cards. AMD is only making an ass of themselves with these tactics.
It is kinda sad that two big games that AMD is pimping show the competition being faster. Hopefully by the time BF4 is ready for release, AMD's dev relationship will pay off and performance will swing in their favor. Otherwise they're going to end up looking stupid for spending the resources on that game.
