    Yes, you should stick with Nvidia. Perhaps wait for the GTX 580! God knows why anyone would want to buy a video card when they are angry with the name of it. Besides that, 5770/5750 are being replaced with 6870/6850. The cards that are replacing 5870/5850 are going to be something like 6970/6950 which will be out next month. I'm not sure if this is difficult to understand or not, but AMD is "tweaking" their card naming.

    The notion that there are huge numbers of consumers spending $100+ on a graphics card without know much about it is unfounded. If you're going to generalize most people at least look at a review before dropping a wad of cash and most reviews compare new cards to old ones. So while ATI and now AMD's naming schemes have always been confusing, people know what they're buying.

    I agree actually, i think it's gonna cause a ton of confusion within the more mainstream groups. Can't for people to scream about how amazing they are for putting what they think their high-end GPU is out for only $250.:shadedshu

    People go off of assumptions, most people will assume the 6870 and 6850 are the high-end GPU's as that is the naming scheme they have been pushing out since the 3 series, it's come accustom to most and i don't think many average individuals will take much time out to read about it. They'll assume the 6870 is the best single GPU card you can get and the 6850 is the second best, while the 6900 is the dual GPU card.

    I used to work in a computer store as a part-time job during my undergraduate study for around 3 years, and I found out that most of the clients don't bother look at reviews, hell even my colleagues never bothered, they used to simply ask me on whatever info they needed. Most of the times they believe things they heard from their friends like GTX 480 gets too hot and noisy or whatever, and consult the sales person on what is the best thing for them within a certain budget. Take my word for it; A LOT of people are going to think that they are getting a bargain on the 6870 thinking that it is the next generation of the 5870. I guess that all is fair in love and war ;)

    Exactly!

    6870 will confuse people? Seriously?

    Is it any different from nVIDIA's GTX460?
    "GTX" has always been nV's high-end part pre/suffix. Now it's used for performance-class parts too.

    AMD was pretty much forced to brand Barts as 6800-series as nV slapped GTX on GF104.

    The transition for Nvidia was much more sound,they didn't switch to that new naming scheme until the 2xx series, so the make up of the cards numbering changed and was easier to refresh in most peoples minds. GTX 260, GTX 275, GTX 280, GTX 285, GTX 295 anything below that was either GTS or GT, right off the bat people could determine what was better then what as opposed to taking the same naming scheme and changing the actual cards performance.

    The 6970 reads like a dual GPU solution:
    -6pin, 8pin
    -300 watt TDP

    However the 6950 reads like a single gpu solution:
    -dual 6pins
    -225 watt TDP (which is 75 watts less than the 6970. That's a big difference for a card in the same tier)




    Could you just post the pic? Use screen grab if you have trouble.

    It looks like MLAA is confirmed to be a selectable option from CCC. This will now compete directly with nv's CSAA mode IMO. Benchmarks competing against the 2 will be very interesting in IQ and overall performance. Also, keep in mind that this AA option is also found in console games. Kill zone 3, for example, will be using it!

    Edit:
    Hmm, it says performance similar to edge-detect but applies to all edges. This may not be as fast as I originally thought.

    I posted it earlier, and you can see the chiphell watermark, so I think the actual source is pretty plain.

    Idk maybe its just me but it looks like MLAA is nothing more than bluring similar to what we all enjoyed in GTA IV.

    Could this be forced? If it could, maybe it entails less of a performance hit? Perhaps therein lies the novelty?

    Awesome so 6870 should = 5850 for the most part and perhaps even out do it, probably in dx11 games.

    Sweet!


    MLAA sounds good as well, will probably be my default AA method for new games : ]

    I know where you are coming from but I think the dual GPU will be the 6990.

    Yeah, would be odd for AMD to not use a core in 2 SKUs(Cayman will be in 6950/6970?). I had originally thought that becuase of this, dual gpu would be 6870x2. But 6990 works too, and seems ot be the right name for this gen's dual-gpu card.

    so this HD 6870 can out perform HD 5850 with less SP and transistor, AMD really do wonder just like what they do, its like HD 4670 all over again

    Smaller DIE and 6-layer PCB .... still they sell it for $250 ... :( ... thats bad ... I hope the price will be lesser ... want to buy a 6870

    So there's nothing new about the HD6000 series really.

    1- 4D? It doesn't really look like it's 4D, 1120/14= 80, 80/16= 5, unless now they have made it 4x20=80, which would be strange, since it is not very efficient to work on quads (4x4 pixels), which is what they usually do...

    2- What a dirty deceptive maneuver to say performance per mm^2 is higher now, it isn't. No die area efficiency has been improved at all, and they use the crippled chip in order to make it look like it has. :shadedshu

    Using the HD5870, the real chip:

    If 1600 SP + 80 TMU == 334 mm^2 then by rule of three 1120 SP + 56 TMU == 233 mm^2 < 255 mm^2.

    I know it doesn't work that way and that same number of ROP/MC contribute to the excess, but die area efficiency has not improved. Period. Consumption has improved a bit though.

    If they want to claim performance per dia area has improved, compare it to the HD5870 @ 900 Mhz, which does X10000++ on Vantage. If you do the math, yep, no increase. :shadedshu

    3- No real better triangle output (still one tri/clock) suggest no real improvement in tesselation.

    Renaming and now this. Anything to do with this? -> AMD hires ex-Nvidia CUDA VP Manju Hegde

    It was not Nvidia per se, it was this guy!

    Thus... He's a witch!!!

    ...and what do we do with witches?

    Burn them!!! :rockout:

    Okay, if this card (namely 6870) hasn't changed at all from 5870/5850 do you expect performance to be less than both then?

    I think that these chips will make better use of the same silicon design, due to the seperate dispatch/set-up engines. If they can get more shaders working at once via this method, then yes, I'd personally consider it a more efficient chip.

    It all depends on how you define efficiency...IPC/watt, maybe, not in die space?

    :)

    I'm not going to hold my breath if you don't mind. Performance on their own slides is no better than what you would expect from a 1120 SP Cypress @ 900 Mhz...

    I agree with that, for sure...I've said the same a page back or so. I'm waiting for a real review...seem like there's potential for alot of what I'd call "5-series issues" to be addressed...everything that I thought was bad/wrong, seems to have changed..DP implementation, dispatch/setup engine, and hopefully, idle clock issues.

    As a refresh, that's perfectly fine. I know that these cards aren't the top dog either, so I do expect alot more out of 69xx-series than these cards. And if all this is true, then 5-series cards will kinda retain thier value, of course, after a modest price drop.

    Personally, think those slides are faked. Liek most good stories, they are grounded in reality, but that doesn't stop them from taking a crazy flight across the interwebs, picking up trash along the way...
