AMD Radeon HD 5970 Specs Surface

In a few days from now, AMD will unveil its new flagship graphics accelerator, the ATI Radeon HD 5970, which will intends to cement the brand's performance leadership over every product from rival NVIDIA. The HD 5970, codenamed "Hemlock", is a dual-GPU accelerator, with two codenamed "Cypress" GPUs in an internal CrossfireX configuration.

Built on the 40 nm process, these GPUs will feature 1600 stream processors each, and will each have a 256-bit wide GDDR5 memory interface to connect to 2 GB of memory (4 GB total on card). The clock speeds are where the specifications of these GPUs differ from their single-GPU avatar, the Radeon HD 5870. The core is clocked at 725 MHz, while the memory runs at 1000 MHz (4000 MHz effective).

The accelerator will not have a rear panel identical to those of other Radeon HD 5000 series accelerators. It has the usual broad air vent occupying one slot, while the other has two DVI-D and one mini DisplayPort (DP) connector. The mini DP connector can give out DVI output using a dongle, and in this way, support for ATI Eyefinity technology remains intact. The NDA covering this accelerator is said to expire on the 19th of November, not very far away.Source: TechConnect Magazine

Just waiting for the GT300 to stomp this card and an X2 version to burry it :toast:
Let us know how that goes.......next year....:laugh:

Your going to be waiting a while, I highly doubt GT300 will be as powerful as whatever card ATI announces the instant NV announces the GT300 is coming to the market. You know ATI will be holding the slap to kill NV's happy day of announcing their DX11 card coming to the market.

system memory amount does not need to exceed system memory, i have never noticed any problems with that.
64 bit OS is just required to get 64 bit extension, and getting over 3.37 gb of system memory running Microsoft windows operating systems
Linux can do 4gb in 32 bit just fine.

The 32bit OS & 8GB (or whatever) of added memory isn't a huge issue, but you will have a performance decrease as the page has to be translated to the higher memory address.


This 4GB card will be seen as a 2GB card if it were to memory map the entire addressable memory as the card is basicly crossfire on a stick. So, no you do not haev 4GB of memory to use, you have 2GB per core.


Any further disagreements from this will result in a cheese grater and salt vinegar treatment to your ass.

I wonder why they went to call it a 5970 and not a 5870x2 or even put it as the 5890.. why 5970?

Was there a 4970?

Maximum 32Bit OS supports for Main system memory is 3.25GB, if you want more than that you need 64bit OS.

Hilarious!

hint: That's not a fixed number.

read this genius, From Microsoft's Mouth

more useful info

http://en.wikipedia.org/wiki/Physical_Address_Extension

anyways im going back to the discussion of the video cards
uh... ok? So what exactly are you trying to say? Or are you just trying to link flood without saying anything?

Here's a link to an old but execllent article on Dan's Data, which is where I learn about this issue long ago.

PAE applies to windows as well as linux.

its not as simple as allowing more than 4GB in a 32 bit operating system, and its nowhere near as good as a true x64 environment

PAE on desktop Windows and cheaper Servers is practically useless because Microsoft put an artificial limit on the addressable space(4GB). For compatibility reasons.

I ment that each GPU has it's own 2GB of ram and it addresses that amount of ram. and that the other gpu has it's own 2GB of ram.

if i'm wrong please correct me.
so am i correct or not?

on the GTX 295 the GPUs are on their seperate PCBs and each GPUs has it's own ram:

just wanting to know if the mini dp needs an active adapter or a passive adapter, planning on using eyefinity on 3 monitors but they are dvi.

So the 5970 is not connected to six monitors? Where's the card they said can be connected to six monitors? Last time I saw the picture of an ATi 5000 card is plugged with 6 monitors and I thought It's the Hemlock or 5970

Just to simplify and shorten things.



3/4/5 generation
5/6/7/8/9 type of card, 5= htpc class, 8 = enthusiast class, 9 = dual GPU
30/50/70/90, card rankings for type of card.

Simples : ]

except that the 4890 wasn't dual GPU

a variety of the ATI cards can, they're a special "eyefinity" variant.

so you can get a 5850, 5870 and 5890 all in normal (3/4 monitors) or eyefinity (6 monitors)

Re-read my friend.

first number
second number

3rd and 4th numbers.

4
8 <- see single GPU
90 <- how pimp the card is in its class.

you say "9 = dual GPU"

i misread that.


you mean the 9 as in x9xx

say... the 4970 that never existed

yes.

the second digit, not the 3rd : ]

For once I didn't make a typo either :p

This may sound lame, but I would actually prefer it if they delayed the launch of the 5970 to the time of release of Fermi. My reasoning is that this card coming out is going to further reduce the stock of available RV870 chips available. Thus, even worse shortages of the more practical 5850/5870.

I mean, in all honesty, how many people buy these $500+ dollar cards at launch? I know only a few who did, and when they sold them to buy a 5870, they only got around $200 (didn't even come close to cover their 5870 cost). That is the cost for buying into new technology, sure, but I'd rather AMD focus on getting more 58xx series cards available on the market. Plus, the 5970 coming out when Fermi does, while serve as a sort of distraction to nVidia.

And as for the clocks, nVidia did the almost the exact same thing with the GTX 295. It was a GTX 285 with the memory bandwidth of the GTX 260 and similar clocks to it, yet had full shader count. And became the GTX 275.
Maybe they have a load of chips that are not clocking as good and will use them ?. And did i not hear that there doing another card after this so maybe that will have default clocks.

Well, someone at wikipedia thinks that HD5890 will be an Evergreen chip with 384bit memory bus.

I would like that. It would make the HD5890 a high-end but very balanced GPU like the HD4890 was already.

No. you are referring to the 50/50 memory splitting of Windows.

I am talking about the number of addresses available in a 32-bit OS. There are only 4G of addresses, and video card memory takes priority over system memory, thus bigger vRAM = less addresses for system RAM = system RAM "disappeared". What's more, video card RAM isn't the only thing that needs addresses, other devices need them too, so there's even less left for system RAM.
50/50 memory splitting? 2GB is just the maximum address space limit a single application is given within a 32-bit system at any given time.
by: Wiki
Ability to run existing 32-bit applications (.exe's) and dynamic link libraries (.dll's). A 32-bit program, if linked with the "large address aware" option, can use up to 4 GB (4,294,967,296 bytes) of virtual address space, as compared to the default 2 GB (2,147,483,648 bytes; optional 3 GB [3,221,225,472 bytes] with /3GB boot.ini option and "large address aware" link option) offered by 32-bit Windows.

i actually have a tool that lets you mod exe files to make the large address aware - very handy.

worked well on games like stalker, supreme commander (original/early patches) and even the sims 3, preventing eventual crashes as they hit the 2GB barrier.



I'm not entirely sure that all 4GB is addressable, i think its another case of "in a perfect world"

a large address space aware app can use whatever is available, if windows sees only 3.25GB of ram, i get the feeling the app may find a similar limit.

Yes, but that requires modding, it is not active by default in the system.
EDIT: from what I know, there are registers (or something) that take the ~0.8GB chunk out of the 4GB, making it 3.2GB addressable, and out of that, some goes to the kernel, etc leaving the lower (numbered) address spaces to apps. Don't quote me though, I'm not spot on... but that's the idea as I know it.
