    Earlier talked about as being a mere speed bump over RV740 that probably locks horns with Radeon HD 4850 or even HD 4870 512 MB in terms of performance in today's applications, Juniper, codename for AMD's newer mainstream GPU that is looking to handle things under the $200 segment, is looking stronger than thought about before on paper, according to recent publication by Anandtech. Breaking away from the previous conception of a GPU with 800 stream processors, a 128-bit GDDR5 memory, and most other vital-stats resembling its ancestor, the report suggests something that's at least 75% as powerful as Cypress.

    It is said to feature 14 SIMD blocks, which going by Cypress' architecture would imply 1120 stream processors (14 x 80 SPs). The report also hints at a stronger memory sub-system to keep up. Instead of a 128-bit wide interface, it hints at 192-bit, GDDR5 at that. This part doesn't seem convincing, as earlier pictures of the card showed it to be holding four memory chips on the reverse side of the PCB, with no fuses to show memory chips that aren't sharing memory channels. Accelerators with 192-bit wide memory interface, should have 6 or 12 memory chips typically. Other numbers include 56 texture memory units (TMUs), and 24 raster operation units (ROPs), if there is a 192-bit memory interface. Two accelerators based on the GPU, Radeon HD 5770 and Radeon HD 5750 should be out around the same time Windows 7 hits retail. Both target sub-$200 price points.

    Now this is gona be the saving grace.
    If these are indeed 75% as good as a 5870 then I am sold.

    Well, great I guess :p

    If they have a single Power connecter, 2 or so might be nice to Crossfire.

    I am thinking about 3 of these hot chicks just to trash my friend's 4870X2 who keeps flexing his e-peen :nutkick:

    The 5870 simply has a hard time fitting in my case, and the 5850 we all know is the shit.

    so.... this means hd5670 will probably have 800 SPs with ddr3 192bits bus maybe ? For around $100 ?

    Most likely 4830 Green performance+DX11 kinda deal.
    So my guess is 128-bit GDDR5.

    well, the only problem I see is that hd4850 is $100.00 already.... and it has better specs besides dx11...

    This is very good...ATI is hitting NVidia with everything they got. Honestly i have no clue how NVidia is going to be able to keep up with ATI at this point. People keep saying GT300 will be a monster but it will be really expensive, the die size is so huge they wouldnt make a profit trying to compete with the 5870.

    Well, the HD5k isn't really much of a threat to nV at this point, they aren't price as competitive as AMD claims.
    It isn't that hard for the GT300s to kick its ass either, even if they just double the specs as AMD did, they still end up on top.

    The GTX 295 is selling cheaper then 5870s here and they perform better, go figure.
    The 5850 is 4/5 fail if they don't have DX11 its 5/5 fail in my option. (Sure the nerd rage comes after me later.)

    COUGH Wha ? double there specs Holly crap would the chip actually still fit on the PCB ?. lol

    Maybe they will do 1/3 of the specs just enough to keep the edge. But even then it be a monster card.

    I am really looking forward to what they actually going to do.

    What i meant is Cost Wise...ATI can lower the Price and make a Profit..but with the NVidia and these giant cores can they come down in price and make a profit?

    Answer to previous post = No, nvidia cant do that.

    Nvidia again, can they rename ? yes. will it still sell? not as good.

    god damnit, ati is selling 70% of all videocards in my country and rising FAST!

    I can go to a lan with 100 people, and 5 has a 8800 GTX or something and rest is damn ati setups lol!

    so 5850 will not be in the sub-200 price range? that sucks, I was hoping to get one:D

    Some people care about power consumption and have an electricity bill to pay :laugh:.

    yep, same in here, in fact, majority of my friend rig already gone to ati (and when ati HD 5870/50 come in here ALL of them will be ATI)

    Nobody is doubting the ROP count. 24 is possible if the bus width is 192-bit GDDR5.

    I said that looking at the pictures, a 192-bit interface looks unlikely as 192-bit needs 6 or 12 memory chips.

    Not at all. 6 chips seated on 32-bit wide data-paths (6 x 32 = 192) or 12 chips with two chips sharing a 32-bit path each (so 6 x 32 = 192 again). If you need examples of these, check out GeForce 9600 GSO / 8800 GS cards with 384 MB or 768 MB of memory (6 or 12 chips).

    An overclocked 4770 will outperform a 4850.. so we should expect performance of a 5770 somewhere between a 4870, and a 4890(?????). Not a bad buy if it's roughly 4890 performance. Not a good buy if less than a 4870.

    Do you actually know that nV is going to utilize the 40nm fabication at TSMC just like ATi?
    They will have no problem fitting a GT300 chip on the card if they just doubled the specs.
    The managed to fit the GT200 @ 65nm on their cards, now think again.

    One thing I am sure, the GTX 260 have no probelm completing with the 4870 even with its huge GPU.

    Not to be a jerk, do you think nV actually cares if ATi owns 100% market share in Norway?
    There is a bigger market in a single province in my country then your whole country, now go figure.

    Well, have you actually calculated how much you save on your power bill?
    I doubt you can actually make up for the price difference during the life of a video card.

    When nV sells a GTX295, they making deficit.... :laugh:

    THe card itself wasnt the problem with competing in terms of performance, Never ever was.
    Nvidia had problems competing with ati, cause of price.
    ati = half the price to make a card
    Ati = Double the profit.

    Nvidia= Double the price to make a card
    Nvidia= Half the profit.


    Now, lets see, mostly in whole europe there is cheaper for an ati card than in usa, atleast in many many places, i've looked in holland, UK, Norway, Sweeden, Denmark, France, Germany and that covers most of it.

    Norway really isnt much diffrent than the rest of europe, except we have more money, and i guess we outdo a typical american province. but not USA Ofc.
    And yeah, europe has a better eco than america(including brazil, mexico etcetc. and represent a bigger market in reality, but americans tend to oversee the fact europe exist from time to time.

    Norwegians isnt ATI fanboys either, the e-tailers reported that ati had a market share of 15 % during 2900XT time, and to 3870/3870X2 they managed to get reasonable 30, then 4xxx came and well they took most of the market.

    Meaning: Ati is really winning.
    Not very strange, nvidia cards like GTS250 did cost as much as 4870 (cheapest vs cheapest)

    Ati might charge more per videocard now though, just because they can.

    Even if nvidia makes a deficit, they still have shareholders investing thus, in the end they make revenue...

    And in business, market share makes more difference than short term profit.
    In terms of market share, ATi is still fighting an up hill battle.
