A little while back, we discussed some of the benefits and disadvantages of ray tracing. Today, we're going to be talking about another potential successor to triangle rasterization: voxel ray casting, the subject of much research by id's John Carmack.

A little more than a year after ATI shocked us with its Radeon HD 4870, it's launching the first DirectX 11 GPU, which packs more than just the promise of next-gen compatibility. We got our hands on a pair of 5870s and spent a week benchmarking them.

Ray tracing is often referred to as the ultimate 3D rendering technique that can put photorealism within reach. We look at how it works, some of the technology's biggest myths, and whether or not ray tracing really represents the future of video games.

With the launch of Larrabee only a few months off, here’s a look at the architecture of Intel’s much-talked-about discrete GPU. How does it look on paper? In what ways is it similar to, and different from Nvidia’s and AMD’s GPUs?

Intel's new Core i7 processors represent a major evolution of the Core 2-series, though a lot of the additions look like they come from AMD's playbook. Is there any truth here or are we the only ones thinking it?

OpenGL 3 and DirectX 11 are both hot topics, but we explain why one of the two next-gen APIs is in a position to succeed and the other is struggling to keep its head above water.

The performance of AMD's Radeon HD 4850 surprised everyone – including Nvidia. The 4870 continues the tradition, delivering excellent price/performance.

Nvidia's GeForce GTX200 focuses on brute force performance, while AMD's ATI division concentrates on features, efficiency and on performance per mm² of die. Is this enough to beat Nvidia?

CUDA software enables GPUs to do tasks normally reserved for CPUs. We look at how it works and its real and potential performance advantages.

Finally, Nvidia has heard our pleas! GT200 is the first real reworking of the G8x architecture. How does it work and perform?

We review the Radeon HD 3850 and 3870 and other mainstream cards using 9 games and 6 resolutions, with a big section on Direct3D 10.1, a new feature of the HD 3000.
