Battlefield 3
Editor’s Note: Earlier today DICE released a patch that among other things is supposed to improve Radeon HD 7000 series performance in the game. We’ll update our numbers to include revised benchmarks as soon as we can.
Its popularity aside, Battlefield 3 may be the most interesting game in our benchmark suite for a single reason: it’s the first AAA DX10+ game. It’s been 5 years since the launch of the first DX10 GPUs, and 3 whole process node shrinks later we’re finally to the point where games are using DX10’s functionality as a baseline rather than an addition. Not surprisingly BF3 is one of the best looking games in our suite, but as with past Battlefield games that beauty comes with a high performance cost
BF3 is an all-around GPU killer, which in the case of the 7700 series doesn’t help matters. Keeping in mind our benchmarks typically trend high, even at 1680 with Medium settings we’re not cracking 60fps with anything less than a GTX 460 1GB. In this case the 7770 should be playable, but intense firefights will definitely drop through the 30fps floor.
In any case the performance of the 7700 series is starting to show some consistency. Once again the 7770 underperforms the 6850, this time by 5%, elsewhere the 7750 noticeably trails the 5770. Nothing on the AMD side is anywhere close to the GTX 560 however.
Looking at our data, I’m a bit worried about the amount of VRAM the 7770 has. 1GB is already not quite enough for some games at 1920 with high quality settings, but BF3 is especially punishing. If we see more games like BF3, I have to wonder if 1GB will be enough for even 1680 in a year’s time.

I thought the 7770 would outperform the 6850 at least. Great review.sigmatau - Wednesday, February 15, 2012 - link
For AMD cards, you look at the second number to indicate performance. An 8 series card like in the 6850 usualy performs as well or slightly better than a next generation 7 series card like the 7770.The 3rd number also indicates performance, but not nearly as much as the second number.

er, not really. A 58xx is faster than a 68xx.sigmatau - Wednesday, February 15, 2012 - link
The 68xx series introduced an anomaly in the formula. But generaly what I stated is true.CeriseCogburn - Saturday, March 10, 2012 - link
The anomaly here is the NVIDIA Gtx460 SMOKES the 7770 on everything, in every test, and costs 33% less.I see the crazed fan base cannot bring themselves to say it.
I'll say it - 19 pages unsaid, over a long time.
THE NVIDIA GTX460 SMOKES THIS CARD RO DEATH, AND THERE'S MORE OF THOSE ON NEWEGG FOR LESS MONEY THAN THE 7770.

My word you are tiresome.nissangtr786 - Thursday, July 5, 2012 - link
Using your logic a gtx 580 smoke the gtx 460.The reason why 7770 costs a bit is because its new technology, power consumption goes down quite a bit. Compare the card to same power consumption of new generation card maybe a 7870 and the 7870 will smoke the gtx 460.
perferformance per watt 7770m smokes the gtx 460.

you seriously need to stop posting. everything you post comes off as rabid nvidia fanatic, because you evidently are one, and you seem to camp outside these benchmarks to say the same thing everytime!! "this thing SMOKES~~~~!! the 7770!!! thats all i look at are the frame rates!!! i dont take anything else into consideration cause im an nvidia superfan"Beararam1 - Thursday, February 16, 2012 - link
Really? I thought the 6870>5850. No?CeriseCogburn - Saturday, March 10, 2012 - link
This 7k series needs some www.verdetrol.com--
LOL - How low can you go amd ?
Seems like more firings and cullings are in the works - or perhaps they already dragged the cat in and are now stuck with perverts.
