Both the players should be "advised" to just show the amount that is ACTUALLY used eg 5Gb. It's becoming nothing more than ePeen now (i now await the 295xx with 12Gb of VRam).

I mean isn't it just daft even with 4K do you really NEED 5Gb of VRam??? Do the GPU's even have the "grunt" to make the most of it?? No doubt we still have "hobbled" Compute performance so even that cant take advantage of the extra memory. Why Nv why??biggrin.gif

Thanx.

It's 10GB or 10GiB... not 10Gb.

Independent GPUs each requires their own dedicated memory space. Memory coherency is an extremely hard computer science issue. There are hundreds of papers on the topic and it is a fundamental limitation of multiple socketed processors. HUMA and other technologies are attempted to create a unified memory space though but it's complicated to say the least.

If NVIDIA could solve the issue trivially, someone would probably win an Turing Award and they could patent the technology that everyone would want.
Once again...

Duckie, I would think you of all people would know GiB != GB. Binary prefixes are close to but not equal to SI. Is VRAM measured in GB or GiB?

I know. But in vernacular when talking about memory, GB is generally accepted even though GiB is technically correct.

VRAM is usually listed in GB as in 4GB while it really is 4GiB.


http://en.wikipedia.org/wiki/Gigabyte
Quote:
When referring to RAM sizes it most often (see binary prefix adoption) has a binary interpretation of 1024^3 bytes, i.e. as an alias for gibibyte.
...
The JEDEC industry consortium continues to recommend the IEEE 100 nomenclature of using the metric prefixes kilo, mega and giga in their binary interpretation for memory manufacturing designations.

It's just confusing. All I know is Windows calls my 1000GB HDDs 931GB. It's an accurate conversion from GB to GiB but they never indicated the binary prefix. The worst part is that it led to a lawsuit and now HDD makers need to put disclaimers of "formatted capacity my differ from advertised capacity" even though it was Microsoft's fault for the confusion.

Woah...
Now I want Tyan to come up with a FT77A sporting 2x(+1) 1600W PSUs to drop in 8x of those babies for 16x the GK110 fun.
5GB is not that bad vs. the 6GB that was attainable through Titans.The net gain in CUDA core aggregate will still be massive.

wow, why on earth would anybody use that kind of setup, where are they supposed to intake air from?

What can we do with 10GB memory or even 5 GB ?

My point exactly I doubt even 4K with all the bells and whistles on KILL would even get near it. Even then i doubt the GPU (s) would have the "muscle". Pointless ePeen........ Like a lot of Nvidias "top" cards *runs away:D

How many TITAN users REALLY use that 6Gb (Yes some with crazy Surround set ups might sure) but the average single TITAN owner with ONE monitor i would THINK would be hard pressed to find a game that would use all that VRam. Still some users see MOAR VRam = better card still even now yet the 290X hangs (and beats sometimes) the TITAN with 2Gb less. Don't get me wrong if i could afford a new Uber card like a 290X or 780Ti i would but Nv especially seem to have some kind of VRam fetish.

AMD manage good 4K performance so i hear with 4Gb so why pointlessly add another slab 'o VRam. Just costs more. would be better if it was faster with higher bus bandwidth (512/1024Bit) surely??

Thanx.

Crysis 3 maxed out at only 2560x1600 uses 2769MB.



Wider buses cost money too. A new high-frequency, very-wide bus would require a memory controller redesign. In addition, it would require more PCB layers for the additional traces.
