‘Radeon RX 490’ News, Updates: Go-To Graphics Card For 4K-Resolution VR, Exploring AMD LiquidVR Deeper

By Jeff Harris, Posted: 11/28/16 02:19PM EST

There are a lot of conflicting reports and rumors about AMD's upcoming graphics card. Putting aside the question of whether Radeon RX 490 is the first Vega 10 graphics card or Polaris 10's last, there are a few things gamers and enthusiasts are now looking forward to about Radeon RX 490.

As many tech websites suggested, Radeon RX 490 will be at the same price range as that of NVIDIA's GeForce GTX 1080. But more importantly, Radeon RX 490 will be the first graphics card to have 4K resolution that is the most important feature in relation to Virtual Reality (VR).

WCCFTech.com revealed that Radeon RX 490 will "target the 4K resolution and be the go-to graphics card for VR". And one of the key factors about this graphics card is having a bus width greater than 256-bits, which is the limit of GeForce GTX 1080.

Radeon RX 490 Bus Width on HBM2

There are conflicting reports about this side; however, given that "Radeon RX 490" could be powered by HBM2, then this will be a big leap from NVIDIA's Pascal-based architecture GPUs. How big will "Radeon RX 490" leap in terms of bus width?

There are 8 channels on an HBM stack, and according to NVIDIA Sr. Research Scientist Mike O'Connor, each channel provides a 128-bit data interface. This translates to 1024-bit. While the first-generation HBM has two stacks, HBM2 has four stacks, thus, translates to 4096-bit. This improvement greatly fulfills the need for 4k Virtual Reality.

Advancement on Virtual Reality with LiquidVR

As the major partner for VR hardware developers like Vive, Oculus and Sulon, AMD's main focus is to maximize the full potential of these virtual reality gadgets, giving the best user experience there is. And to bring this forward, AMD developed LiquidVR technology.

Advancements of user experiences are pretty much the critical part of virtual reality, with the latest DirectX versions and higher resolution to go along the headset. Should Radeon RX 490 be accompanied with the second-generation High Bandwidth Memory technology, bringing out the most with its 16GB RAM, 4096-bit bus width and purportedly 716.8 GB/s memory bandwidth as per VideoCardz.com should be easy.
