Nvidias new way of using VRAM?

[D1craig]

When the 900 series of cards where released it was said by Nvidia that these cards will be able to handle the needs of more VRAM because of the way they use it... Or something along them lines.

Now it's been over 6 months since the release I have not seen one case where 4GB on a AMD card is less valuable than 4GB on a Nvidia card. What happened to this?

Will probably come to light that I have misunderstood something along the way lol.

Have you not heard about the GTX 970 !!!

I think I will get my coat.

I own one and tbh not used that much vram anyway.

Yer, I think you have misunderstood and it was the way the 256bit bus coped with memory compression. It wouldn't actually mean using less VRAM, just a better way of dealing with compression.

AMD do the same as well.

Edit:

This article explains it far better than I could

Scroll down to Colour Compression.

a few words in your post made alarm bells go off in my head and then i thought oh yeah that is what it said.

Their claim was that the 970/980 had advanced HW memory compression that made their 224GB/s bandwidth an effective 300GB/s, and would let them hold up to 5GB in VRAM.

It was ********

that was how i was thinking it worked and how i understood it tbh.
