AMD Juniper Early Specs Surface
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.

If these are indeed 75% as good as a 5870 then I am sold.
If they have a single Power connecter, 2 or so might be nice to Crossfire.
The 5870 simply has a hard time fitting in my case, and the 5850 we all know is the shit.
So my guess is 128-bit GDDR5.
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.)
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.
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!
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).
sry for the mixup
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.
(thats waiii so hard to get a GTX295 and GTX 285)
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.
In terms of market share, ATi is still fighting an up hill battle.
Nvidia still makes the bulk of its money through produce sells for large computer distributers like Dell and HP. ATI use to earn the bulk of its money through sell of the image controllers in LCD TV's. I still think they may a lot of money there now.
