After 3dfx collapsed, there was a brief period of time when it looked as though Imagination Technologies might establish itself as a third option. Ultimately, that didn't happen — the company's tile-based rendering solution, Kyro, failed to gain mass-market support and faded after two generations. Now, there's a flurry of evidence to suggest that Imagination Technologies plans to re-enter PC market, but from the opposite direction. Rather than building expensive discrete solutions, IT is focused on deploying GPUs that can challenge Nvidia and AMD solutions in tablets, mobile phones, and possibly netbooks. Over the past two weeks, Imagination Technologies has announced new, higher-end versions of its Power VR Series 6 GPU, claiming that the new Power VR G6230 and G6430 go "'all out', adding incremental extra area for maximum performance whilst minimising power consumption." There's a new ray-tracing SDK out and a post discussing how PowerVR is utilizing GPU Compute and OpenCL to offload and accelerate CPU-centric tasks."
