Sapphire R9 290 Tri-X OC Review (1600p, Ultra HD 4K)

Sapphire R9 290 Tri-X OC Review (1600p, Ultra HD 4K) | Ultra High Definition Television (UHDTV) | Scoop.it


In November AMD released their reference R9 290 and while we were impressed with the frame rate performance we certainly didn’t find it fun dealing with the noisy, ill performing reference cooler.


It has been some time coming, but today we look at the first custom cooled, overclocked card from partner Sapphire. It features their tasty Tri X cooler.

Is this the card you need in your new system build as we head into 2014?

Frame Rating: High End GPUs Benchmarked at 4K Resolutions

Frame Rating: High End GPUs Benchmarked at 4K Resolutions | Ultra High Definition Television (UHDTV) | Scoop.it

 

Both NVIDIA and AMD current generation graphics cards support output to this TV at 3840x2160 using an HDMI cable. 

 

You might be surprised to find that HDMI 1.4 can support 4K resolutions, but it can do so only at 30 Hz (60 Hz 4K TVs won't be available until 2014 most likely), half the refresh rate of most TVs and monitors at 60 Hz. 

 

That doesn't mean we are limited to 30 FPS of performance though, far from it. 

 

As you'll see in our testing on the coming pages we were able to push out much higher frame rates using some very high end graphics solutions.

Todays GPUs wont be able to handle it. as the afforadable GPU £100 - £200 wont be. but newer GPUs that are costing over £250 plus that have high Vram will have a more stable framerate because they are designed for 4K and have more video memeory to support. from what i see 1080p is needing atleast with 2GB of VRAM but 4k is 4 times as large the recomendation will be 8GB and not even ultra high end GPU's have that amount! the high amount is 6GB but have been tested on 4K and runs fine. but i still feel there is more to a clomplish before 4K becomes cheaper for the public to use.
