1GB is still enough for most purposes, but of course it is a bit of a chicken-egg scenario. There are several 2 GB 5800-series cards out there, so I'm sure it won't take long for 6900 to get a custom 2GB model.
That sheet isn't made by a rumor site. That is directly from the presentation materials AMD gives to their motherboard partners.Quote:

Tbh I think nvidia wont be able to win on the top but I think they will be very agressive with the mainstream. I think the gtx 560 will be very tough to beat since the 6870/6850 have a hard time vs the oc 460s already.
I have my money on nvidia doing very well with 560 and not so competitive with 580. ati better watch out on the minstream.
Agreed on the principle idea of your post, though i must say we still have to prove whether GTX 560 with a full fledged GF104 chip on it would be that superior against HD 6870. I think the base performance will be around the same, perhaps GTX 560 would have higher OC ceiling, while HD 6870 will consume less power for equal performance.Quote:

Whats with the anemic overclock. If your going to pay 20 extra dollars, you better get more than 20mhz, especially when the cooler is the same. If 20mhz is turbo, then the degree's of separation between words just got cheap. Although the memory is overclocked 5 or 6 percent, it still not worth 20 bucks.Quote:

E.g EVGA gtx 460 ftw is overclocked 175mhz and it cost 20 dollars extra. With MSI you get a slightly lower overclock and a better cooler, same with ASUS and gigabyte.
How strict is AMD overclocking policy? There are only 3 cards that are overclocked among the 6850 and 6870 at newegg and they are overclocked between 15-25mhz. I know they are not showing good ocing at stock volts, but I think 2-3% overclock hardly warrant a premium in pricing. I certainly hope people are not foolish enough to pay extra for such a tiny overclock.

Excellent article, your work is very much appreciated SKYMTL :up:Quote:

The price between an EVGA GTX470($259) and XFX 6870($254) is essentially the same. Many people are probably willing to pay the extra $15 on a 6870 for the better warranty that XFX offers
Excellent work... My only gripe is the fact that 8xAA was only tested at 2560x1600, when very few people who would run one of these single card would run that resolution and even attempt that AA level. Would've been nice to see it at 1920x1200.Quote:

i think he does that to determine the choke point. if he did it a bunch of times at different resolutions it would have weighed in too much on the summary comparison. and if he did it a lower resolution, it might not have cause any kind of struggle (but i think your onto something). repeat the test, but for highest cards it would run at 2560, mid range at 1920, and low at 1650Quote:

Yeah, I was also requesting it because I'm curious what card wins at 1920 with 8xAA because that's the resolution I play at, as does most people I would think that happen to use these price level cards.Quote:

AMD Morphological AA Performance and IQ Review
http://www.hardocp.com/article/2010/...ance_iq_reviewQuote:
We take an in-depth look at AMD’s new Morphological AA technology introduced with the Radeon HD 6870 and Radeon HD 6850. We will evaluate performance and image quality with the new antialiasing feature. This new feature is poised to provide an improved gameplay experience.

The Bottom Line
Morphological AA is the wave of the future. We believe that image quality enhancements of this nature are going to be the key to providing a better gameplay experience. The GPUs of today are powerful beasts, and it is no surprise to anyone that there is unused potential lurking within. Some are trying to expose that potential by forcing proprietary methods of using the GPU for accelerating physics in games. Others are using that same potential in the GPU to apply filters using industry standards that help one of the most annoying and image quality sucking facts about gaming, aliasing.
forcing proprietary methods... some form of lobbying method, lobbying leads to inefficiencies, I would like to see a standard across the board that is not proprietary that all competitors abide by (IQ respective) ... would OpenGL be an example???
Surely MAA looks like a total winner, and I would like to see both camps adopt it, so that we can see less bull on the highly inefficient proprietary iq accelerators
MLAA is a "proprietary" standard that is used only on AMD cards. It leverages DirectCompute which is hardly what I would call an "open" standard either. Seems there were some wires crossed somewhere...
Is MLAA in particular the wave of the future? Heck no. HOWEVER, using DirectCompute to add post processing effects will likely be the way things end up going and MLAA does blaze a path in terms of AA algorithms being applied through DirectCompute hooks.
All things being fair and balanced, NVIDIA was applying compute after-effects back when Just Cause 2 was released (enhanced water rendering & the bokeh filter) as well. ;)
AMD Radeon HD 6850 Overclocking Roundup: Asus, XFX, & MSI
http://www.anandtech.com/show/4002/a...p-asus-xfx-msi
i can confirm their findings; temperature and noise gets through the roof once you hit 950mhz; i managed to push my card to 1050mhz core but it required 1.3v (Sapphire Trixx has a higher limit than afterburner) and ttemps with the fan @100% jumped from 60 to 80°C; if you set it to 90% you get an instant crash so 80°C is the limit when overclocking these cards...
it seems like 950mhz core is the sweet spot for 6850s as power consumption is still ok at this level and you're getting mem bandwidth limited even with 1150-1200 mem clock (my card does 1200 without artifacting; 1230 shows artifacts and 1240 causes a driver reload)
great review and i think that 6850 is a much better value than 6870 and slightly better than GTX460 especially with overclocks and a properly modded bios with 2D clocks :)
So it looks like people with 6850 need to pray for some good memory OC instead of just upping the core.
good review, but i was kinda mad that used a very simple method for handling the fan speed, by leaving it on autoQuote:

i agree... does your sapphire have heatsinks on memory and vrm?Quote:
