CHIP has the original "Dual" Processor Unit, each PU contains 160 VLIW (vulgar understanding of the words Where there are two RV770 form a RV870), but certainly not in now with a simple package prices

Basically instead of making a mega cores with 1600 SP you make two 800 SP cores on the same die with fast inter connects to support SFR. This way you can concentrate on refining process tech for the lower trans count 800 SP cores. It will not be as fast as a native 1600 SP chip but it will be easier to produce. And it appears that the cores share a single memory controller. So I guess instead of calling it dual core it may be better to call it dual shader mega clusters.
Either way a source has hinted that the new card R870 will be two GPU dies glued together sharing a memory bus. This is pretty much the exact same that was said before the R700 launch, and while we can't confirm this, similar information has been posted over at Chiphell.
Both are basically saying that AMD has glued two RV870 GPUs together
well they glued two rv770's together to make the rv870. later nordic goes on to talk about "quad-fire on a stick"... this is where you get to see 4 rv770's in the R800 (but only two die).
AMD unveiled its next-gen GPU, and secretive networked gaming company OTOY used it to power a demo of Crysis running on an iPhone. Believe it or not, it really worked ...
^^ Impressive tech too, and you don't need to stream 1080p games over the net, you can make the server renderer use a much lower resolution, as the one in your phone.
I'm sorry but that's not how it works. Plug the intake of a turbo, does it start pulling air in from the outlet? No, it simply hits the choke point. It's the same for this type of fan - they operate on the same physical principle. They could be intakes if they are ducted to the inlet side of the fan, but just having two holes there would make them outlets.
Well my arugment was not whether or not they defyed the laws of this type of fans physics, just that when the top opening was blocked that through some manner or ducting they would act as a draw in point for fresh air, im not dissmissing the fact that the centrifugal blower only can draw air from the top, just that when it was blocked some manner would allow it to draw from those ports
Quote:
The intake vent on the back end serves as the main source of intake air when the card is in an SLI configuration. When run in a multi GPU setup, these cards are incredibly close to each other, so another avenue for air intake had to be used.
You can see here that the fan is shrouded to prevent it from throwing the air in all directions and out of the intake, i assume the 5870 is the same, you can see the gap between the blower and chassis which is probley the draw point where the lip is cut out to allow intake... soo if you put ur finger in the intake and felt upwards there would be a small gap to feed air from the intake of the blower.. if not the fan shroud and the top chassis are two seperate pieces that dont even touch.. i assume they are air "intake" and not exhaust
You can see here the same principle, the shroud for the radial fan hides the fan, but i bet there is just enough room to force those inlets to draw if the top becomes blocked

There's 4 (option for 5) vGPU phases using what it seems Volterra VT1195SFs, +1 other Volterra VRM for an unknown load, likely uncore like on HD4890, and finally 1+1 with unknown parts for memory. Looks like a very powerful VRM.

The fan is clearly shrouded near the power connectors to avoid sending airflow that way. But without a disassembled view of the heatsink, it's hard to say if the rest of the fan on that side is shrouded. If it is completely shrouded on that side and there is a gap between the top of the bezel and the shroud on that side then the fan could conceivably draw some fresh air from those holes. But the airflow would be restricted to the size of the gap, which is certainly much smaller then the holes.

Well, i think the principle is any air, is good air. I just blocked my gtx280 fan and it seems to draw air in from the rear
If a single 5870 can play a modern game at full 7680x3200 resolution (across six displays), does this mean we will not have any performance loss on a single monitor going from 1440x900 to 1600x1200? I mean, if these things barely choke on six displays, we shouldn't see anything happen on a single monitor regardless of the resolution. This will revolutionize gaming, and GPU reviewing. Truly, this is an amazing feat.
Hail fellow warrior albeit a surat Mercenary. I Hail to you from the Clans, Ghost Bear that is (Yes freebirth we still do and shall always view mercenaries with great disdain!) I have long been an honorable warrior of the mighty Warden Clan Ghost Bear the honorable Bekker surname. I salute your tenacity to show your freebirth sibkin their ignorance!

I want a 5870 NOW!
Welll, hold on there.. Those photos were not very detailed, and we dont know if....
a) AA/AF was on
b) The type of system running the cards
c) Any of game tweaks etc
d) If they looked utterly crap
e) How responsive was the game, was it fluid and sexy or laggy and jittery
Im holding judgement until i see some metric proof

....and maybe 10 or 20 others reported this. These GPUs played these games at these high resolutions and with settings turned up. Not an easy thing to accomplish. I think we're really seeing something amazing here. Maybe it hasn't fully sunken in yet, but AMD really did this!

Okay, your point was made in the very first article... but i still dont understand how ATI could have a trick this BIG up their sleeve. To have that much power in a single card... to be able to drive so many high quality screens at such high quality

The specs of these cards exceed 2x the specs of my 4870 (ROPs and TMUs especially). Their ability to do AA and AF has much more than just doubled. Sure, these GPUs cant' do PhysX, but they seem to be capable of doing everything a gamer wants out of them. I can't wait to try a F@H client on a 1600 stream processor GPU too.
