Just in case anyone was in doubt that the 4K revolution is happening, Nvidia has just announced that its much anticipated Tegra 4 mobile chipset will include "4K Ultra-High-Def video support"
It's hard to believe it, but this demo is running on a mobile chipset, in real time
GPU acceleration - using a graphics card to do graphics-intensive tasks that the CPU would otherwise have to do - has transformed 3D and compositing on desktop and laptop computers. Here's a short video from Eyon that illustrates this and is a good primer for anyone unfamiliar with the concept. It also explains the difference between Nvidia's GeForce and Quadro cards.
An Nvidia hardware launch is always a reason to get excited, not least when it is their professional GPUs that are being launched. These cards – the Quadro family, only appear once in every two years or so, so when they do, it tends to present us with a significant jump forward, both in terms of features and performance.

Pure computing power is moving on in leaps and bounds. What can you do when you pile everything into a top computer workstation?
Most of us despair when we see technology and science presented to a non-technical audience on TV. It's not easy to explain stuff in the short time available, but often it's over-simplified to the point of being nonsensical. So how does a national UK broadcaster deal with the topic of 4K?
Ray Tracing has always produced the most spectacular results of all CGI techniques. We've all seen those images of chrome balls on chess-boards, with every reflection - even between multiple balls - faithfully rendered. And "rendered" is the important word here, because, until now, real-time ray tracing on anything other than a supercomputer has been impossible.
