[Atomic MPC] AMD gives the 7970 a boost (to 1GHz) - Page 19

post #181 of 276
Go AMD, don't see all the fuss with the GTX 680.... And I've had my fair share of nvidia cards.

All that wait and all that hype and it only ended up being around 6% faster on average and that shrunk as the resolution increased.

Whereas in a game like Alan Wake or Metro 2033 which struggle at 1080p maxed out to hit 60 fps there is a significant difference in game playability on HD 7970 OC . The HD 7970 is a true single card beast aimed at maximum performance showing no limitations like the GTX 680 which can be bandwidth constrained even in today's games.
Look at the perf scaling from GTX 580 to GTX 680 which is < 20%. The GTX 580 is in fact faster than HD 6970 in this game. So the performance jump from Fermi to kepler is much lesser than Cayman to Tahiti. When GTX 680 is bandwidth constrained its going to look pretty bad. And we aren't even talking about games in the future.

The point is driven home by the fact that HD 7970 at 1125 Mhz is 66% faster than HD 6970 and 25% faster than GTX 680
http://www.guru3d.com/article/radeon-hd-7970-overclock-guide/12
the GTX 680 is a good card but people who think its superior to HD 7970 are just dreaming. biggrin.gif the GTX 680 is more power efficient than HD 7970 but that same power efficiency becomes irrelevant when its performance is held back significantly by bandwidth issues. I can't speak for others but if I were spending USD 500 i would rather spend it on a more future proof card even if I have to cope with a card which consumes more power. smile.gif

I lolled. But maybe that's just because I have both. wink.gif The 7970 is good, but come on, seriously? rolleyes.gif

People seem to forget also that what the HD 7970 gives up in power efficiency it makes up for in compute performance.

For people that are in it for the pure gaming aspects of the card, that doesn't really matter, but when you consider the HD 7970 as the total package, it is the superior card. Unless Nvidia releases "big kepler" with better compute and gaming performance, I think AMD may have outgunned Nvidia this generation.

Again, that's my personal opinion. Most people aren't going to agree with me on this and they're going to use gaming benchmarks to disprove me, but all that proves is that nvidia maintains higher framerates in instances where it doesn't really matter.

Seriously Pistol,


You and your logic... Just stop.. OCN is obviously a haven for emotional arguments and not those seated in empirical evidence. HOWEVER, just to give you some intellectual meat to chew on. I dont see anyone in the BOINC or F@H threads pointing to how epic the 680 is.


Sure for Gaming the 680 wins (at stock) but when you take into account the total picture you see it was gimped in compute. Not everything in the world is gaming.

For reference, I think the GTX 690 is an amazing card due to its power efficiency. I think the GTX 680 is a great gaming card, but why pay a little more for marginally better gaming performance when you can pay a little less and have nearly as good gaming performance and superior compute performance? If my logic is flawed, go ahead and explain it to me. Thanks.

True, not as of yet but the 7990 hasnt come out yet to say same as of the latest dual GPU's.

Reviews are showing the 690 comes within 2%-6% of 680's in SLI and is the closest any dual GPU has come out within comparison of its SLI brethren.

This my friend may be the time Nvidias dual GPU does. smile.gif We'll see when AMD figures out thier crossfire driver issues prior to release with a functional dual GPU how it compares in perfomance, power consumption, and temperatures.

I have to say the HD 7970 chip is the better chip compared to GTX 680. Period. I have my own reasons for it.

Gaming Performance in the most demanding games is with HD 7970 OC. Compute performance is with HD 7970. HD 7970 is more future proof and will not run into bandwidth constrained scenarios like GTX 680. Also the fact that we are talking about 1050 Mhz (1250 Mhz OC'd with stock voltage) makes it a much better buy than GTX 680 if priced similarly. thumb.gif
