HD 68xx reviews and discussions

HD6850 is a bit better than the GTX460.
HD6870 is a (little more) bit better than the HD5850.

So?

HD6850 > GTX460 in EVERY aspect.
HD6870 > HD5850 in EVERY aspect.
HD6870 vs GTX470 is the current competition (from HardOCP).

AMD is in a win-win situation. Consumers are in a win-win situation.

*sips a cup of tea*
Life is good.

I can tell you the EXACT performance of the 5900 series.

6850 ($188) is 4% faster than 460 1G, priced $10 more
6870 ($240) is 7% slower than 470, priced $20 less

these are main competitions.

460 768Mb is now priced at $150, and has no competition from AMD. This is a good buy now if you are in that price range.

NV cards seem to have more head room for OC, while AMD cards all supports 3+ displays and draw less powers.

PS. Anandtech actually reviewed a 460 FTW OC version in their official review of 6870/6850 due to the pressure from NV ( they did wrote several paragraph disclaimer saying its not right, but then they turn around used it anyway)

Pfft, then my GTS 250 Sli is better than a 6850 because my GTS 250 in SLI and better than a single 460.

Zen you're...not too bright. The HD6870 is better than the HD5850 in EVERY aspect. Tessellation, power (only idle, really), price, performance, size, efficiency, EVERYTHING.

The HD6970 is the GTX480 killer...or it should be, anyways.

Does anyone have a 6k series card yet that would like to discuss their experience with it?

Such as: Display experience? noise? frame rates? over all game experience? over all card experience?

I'm a nvidia fanboy and I'm seriously considering the AMD 6870.

^ lol so true

Cayman...rumors of Cayman.

Deal with dude, I was a hairs breadth away from closing it myself.

That's funny, in my experience it's been the opposite.. lol

I doubt the rumors that the Northern Islands will be literally Twice as fast as the previous generation. Maybe 40-50% faster like the ATI 4K - 5K series.

The HD 5xxx and the SI are almost identical in performance. Except the SI scale much better in CF, and use less energy.

The revolutionary GPU performance milestone won't be until 2013 with Nvidia's "Maxwell" cards, which are said to have roughly 16 times the performance of the current Fermi's - the real Crysis killers!

Imagine running Crysis/Warhead on very high/enthusiast at 2560x1600 with 8x AA, maybe even with graphical mods, and get over 100 FPS!

If the 6970s are double the 6870s, and if the new arch is more effective, in DX11 games, add in MLAA, its very possible

If rumors are true, first, were looking at an improved arch, one even moreso than the 68xxs
Then, were looking at 1920 or 2240 shaders, which, as Ive said, scales much better in higher numbers, whether its a simple MC, the 4 wide or other tweaks, or possibly all of the above, it will be a monster, and I dont say this lightly
It may also just be a 1600 shader card, which will still be close to 5970 levels

OT
Heres a nice overview of Fermis arch
http://www.beyond3d.com/content/reviews/55/1

The wriggle room weve seen already shows a +25% improvement, if the 6970 has 1600 shaders
If theyve made better improvements, as the drivers are stating they have for the 69xx cards, and theyre bigger, you can at least double that 25%

So, Wat about the Hd6990s?
dual HD 6950 chips?

Well...the only reason AMD prices increases with 5xxx was because when they stuck their head up, Nvidia didnt have squat. No competition=higher prices, so they jumped the prices up. AMD has competition time, and while it seems to me 6850>460 and 6870>470, its still relatively close. If AMD jumped prices up by even just $10, it would be bad. So they likely wont raise them. HOWEVER, theres a rumor circulating these Nvidia price drops are only 3 weeks. Maybe to make them not look as good in the beginning. Maybe its wrong. However, if its true, then AMD would likely raise prices as well. AMD has control in a way, if Nvidia lowers prices, they lower them to make their cards look still better, Nvidia raises them, AMD is free to raise them. Somewhat like staying 1 step behind and 3 steps forward.

Sorry, yeah, 3 weeks. Typo.

6950/6970 will be single GPU card

6990 probably will be two GPU card

Why do people keep thinking these are replacements for the 57xx?

It is the 58xx that they replace, they may not over take the 5870 but were no designed to.

The 57xx are being retained the 68xx replaces the 58xx.

When are the 69xx coming out?

i seriously hope the 6750 and 6770 aren't just the 5750/5770 rebranded. wont fit with the generation, the 6670 might have better performance than a 5750. no increase in performance for tessellation. no power adjustments (the 5750 does still give good performance per watt). if they could get the 6770 to compete with the gtx 460 768mb version then it could be good competition.

i don't know what prices in the US are like, but in Canada these cards seem like gods. The cheapest GTX 460 1gb is 215$ after sale and rebate and the 6850 is 184$ and it out performs it in virtually every benchmark? Then the 6870 is consistently 30$ cheaper than the closest 5850 and it outperforms it in every respect!
These cards are awesome!

So the Maxwell cards won't be 16 times more powerful than the Fermi's?

they arent releasing the lower end of the 6xxx series this year either. it would be a bit weird if there was no 67xx series.

I can't help but wonder how many sites were supplied with the "dodgy" 6850's rather than the ones that the ordinary consumers will be able to buy.
