970 and 980 @ 256BIT----->4k Support

Dj Spiel · Oct 22, 2014

Can someone explain in a nutshell how this is good for 4k Support?

While the R9 290x (my current card) is at 512-Bit and the GTX 780 is @ 384-Bit

We all know the higher the better. Especialluy when you're running higher resolutions. My question is....how are these new gen cards compansating for the lower bit @ 256?

I am curious because I am not quite happy with my R9 290x and I am thinking of moving to (1) 780 *with another downt he road perhaps) or (1) GTX 970 or 980 (but from the reviews it seems that a OC'd 970 performs just as fine as a GTX 980)

There's a new memory compression that allows better utilization of the memory bus, therefore 256-bit is more effective than it used to be as of the 9xx series.

I wouldn't move personally unless you wanted to save a bit on power and and be a little faster all around.

The next lower card can usually come close, match or at times even beat its bigger brother... but you forget that you can just as easily overclock that 980 and put itself back in the lead.

I think this 256bit bottlenecks the bandwidth somehow.

If you check the 970/290x comparison charts on anandtech, you'll notice that the 970 does better then the 290x on lower resolutions while the AMD card takes the advantage on higher ones.

You can also consider two 970s.

Dj Spiel · Oct 23, 2014

Not really worried about lower resolutions as I run a SAMSUNG UD590 Series U28D590D Black @ 4K, 3840 x 2160 Resolution(UHD), 60Hz (DP)

Exactly what I was looking for. Thanks!

Then I am with Earthdog, keep your 290X's, going nVidia is more than a sidegrade.

Dj Spiel · Oct 23, 2014

The problem I have is with the drivers for ATI/AMD they are horrible.

If money is not an issue, wait for the 980ti then (or whatever it will be called).

Oh? Ive been on and off of them for quite a while with no more issues than with the NVIDIA drivers... this on a 295x2.

What problems do you have with the drivers?

manu2b · Oct 23, 2014

I had no issue either, with both 280x's and 290x's.

NiHaoMike · Oct 24, 2014

AMD was once known for horrible drivers but they have improved considerably over the years. They now even support VDPAU, which used to be exclusive to Nvidia. Still, I stuck with Nvidia since they're the "golden standard" ever since the 64 bit transition gave them just the right opportunity to pull ahead.
