Palit is making a gtx580 with 3gb of memory and possibly surround on one card..

This comes right from Palit.

Mabe this is the gtx580 3gb card here that will do 3d surround on 1 card?

http://www.tomshardware.com/us/press/Palit-GTX580-52

Wonder if they will make a gtx570 with 2.5gb?

To get 3 GB they’ll have to change Fermi’s ROP/memory configuration. I wonder what route they’ll take?

What your saying its not as simple as putting another 1.5gb of memory on the card?

Edit: or do they just use 256mb chips x 12 instead of 128mb x 12?

ROPs are tied to memory partitions. They would either need to change the coupling ratio, or the counts of both.

Is it different for the gtx460? How did they go from 1gb to 2gb.

 

[Lonyo]

Yeah, surely they just use higher density memory chips?
It's the surround on one card which is more interesting, unless they are just saying it can do it (... as long as you get two).

They have a gtx460 that does 4 displays/surround so I don't doubt them.

 

[Skurge]

I don't see where they say it can do surround with one card. Also, can that 460 run surround or can it just 4 monitors at the same time? I not quite sure.

 

[Infrnl]

where do they have a gtx 460 that runs 4 monitors? Thats what i need. 1 card to run at least 3

 

[notty22]

As I understand it, they can double up the memory amount without changing anything, thats all they can do. It won't support multi- monitors without 2 video controllers, which takes 2 gpu's.
Here a review and picture of a 2gb gtx 460
http://www.overclock3d.net/reviews/gpu_displays/gainward_gtx460_golden_sample_review/2
They added 8 extra memory chips on the backside

Nvidia is doing something like this with the OEM gts 440, it has a 192 bit memory interface (like the gimped gtx 460~768) ,its memory configuration could be 768, 1.5, 3 gb
They are offering it in 1.5 and 3.0 versions

And yes Skurge it does surround and 3d.

Then explain how the gtx460 card linked above uses 4 monitors and will do surround on one card?


"Quadruple-Display Ready
The ZOTAC GeForce GTX 460 3DP packs three DisplayPort and one dual-link DVI that are capable of driving up to four independent displays simultaneously with a combined resolution up to 6400 x1200.

"The ZOTAC GeForce GTX 460 3DP enables multi-monitor computing with up to four simultaneous displays from a single graphics card for enhanced productivity, gaming and multimedia"

 

[notty22]

Its obviously doing it through those 3 display ports which are non standard on any other nvidia card .
I'd love for you to find a review of that actually working. Spanned gaming across 3 monitors. I knew there was one model with 1 display port.

I can almost guarantee the gtx 580 you linked to , will not use that non standard output configuration. Dropped a dvi port, to uitlize 3 display ports. Nvidia's drivers and support don't use this method for 3d surround vision.

edit: Its probably a cool idea, but what worries me is, they must use a 'custom' driver for this to work. With all the quirks that can happen on the users end with different motherboards/monitor configurations this might not be ideal or elegant as the descriptions sounds.

I would like to see some one actually running that. "Surround Ready" and "capable of driving up to four independent displays simultaneously with a combined resolution up to 6400 x1200". I'm not saying it doesn't for sure, but that wording can be interpreted differently i guess. I just don't see it supporting surround.

I don't see why the 580 couldn't have either double density ram or double the amount of ram chips to equal 3GB without the reworking.

OK, I just did a little research , it seems it can do surround but with only 3 1600x1050 displays. So 3 ,22 inch monitors for surround max.
I wouldn't think you would want to do more with a card of this speed anyway, especially with only 1 gb of memory.

But it looks like it can be done. :thumbsup:

what do you mean? there have always been cards with various memory amounts while ROPs remained the same. for example there have been 256 bit cards with 512mb, 1gb and 2gb of memory and nothing else changed at all.

 

[Castiel]

580's should come from Nvidia with 3GB. Palit shouldn't need to do it.

Actually 3gb is way too much but they have no choice. Sure would be nice to see a gtx570 2.5gb.

 

[BFG10K]

what do you mean?

ROPs have been closely tied to memory controllers since the G80 days.

there have always been cards with various memory amounts while ROPs remained the same. for example there have been 256 bit cards with 512mb, 1gb and 2gb of memory and nothing else changed at all.

That’s because the ROP/memory ratio changed, like I said earlier. But there’s a limit to what can be done without changing the layout.

It’s not a coincidence that the GTX460 1 GB also has more ROPs than the 768 MB version. It’s also not a coincidence that the 768’s ROP count is the same as G80 derivatives with 768 MB.

I thought this was your area of expertise? the gtx460 1gb has more ROPs because its a 256bit card where the 768 model is 192bit. thats the bus width that is tied to the ROPs not the amount of memory. a 192bit card can have 384,768,1536 and so on. a 256bit card can have 256,512,1024 and so on. the ROPs mean nothing when it comes to adding additional memory capacity. thats why some card makers slap on large amounts of memory to make more of a profit.

And yet the 8800 GTX had 384 bit memory bus but it also had 768 MB VRAM and 24 ROPs, same as a GTX460. Things aren’t quite as simple as you make them out to be.

a 192bit card can have 384,768,1536 and so on. a 256bit card can have 256,512,1024 and so on. the ROPs mean nothing when it comes to adding additional memory capacity. thats why some card makers slap on large amounts of memory to make more of a profit.

I never claimed otherwise. Read carefully what I said and keep reading it until you understand it.

what does that have to do with what I said? the gtx460 has 192bit bus and 24 ROPs but so what? that doesn't mean it cant have more memory than 768mb. you do know there are gtx460 256bit 2gb models that have the same number of ROPs as the 1gb models? plenty of Nvidia cards have had varying amounts of memory while using the same memory bus width and amount of ROPs did not change. a gtx580 with 3gb is nothing more than a gtx580 1.5gb but with more memory added. thats because again, ROPs are tied to the bus width not the amount of memory.

I did read that but then you gave the example of the 8800gtx 768mb having the same amount of ROPs as the gtx460 768mb. that clearly still looks like you are saying that ROPs is tied to memory amount. the 8800gts 640mb and 320mb both had the same number of ROPs though because its the bus width that they are tied to.

 

[BFG10K]

Well they are if you want to decrease the memory amount. But that’s not what I’m talking about.

Let me explain it to you simply: I was speculating whether this would be a simple ROP/memory ratio change, or if anything else would change. Such a high-end card might lend itself to more exotic changes.
