Vivante Mobile GPU Architecture Gains Traction

Over the past few years, a handful of mobile graphics companies have emerged but the top dog, by far, has been Imagination Technologies, with Qualcomm, Nvidia and ARM all picking up significant businesses of their own as well. But now, there's a new kid on the block — a company with a tiny, highly customized GPU, a number of recent design wins, and a strong product portfolio. Vivante got started in 2004 and started licensing its GPU designs in 2007. The company's early wins have been in Eastern markets, but this past year, it's begun to show up in devices intended for the West, including the Samsung Galaxy Tab 3 and Google's Chromecast. Vivante has taken a different approach to core design from most of the other companies that play in this space. All modern GPUs are explicitly designed to be modular and scalable. Typically what that means is that a company like Nvidia or AMD defines a single compute unit that can be duplicated throughout the GPU design. Vivante's GPUs are modular as well, but with a much finer level of granularity. Each of the three shaded blocks (3-D Pipeline, Vector Graphics Pipeline, 2-D Pipeline) can be segmented or stacked into various configurations. A GPU core, in other words, could contain more ultra-threaded shaders, or additional vector graphics engines, up to 32 cores in total. One of the advantages of this tiny, modular architecture is that you can clock the cores like gangbusters. According to Vivante, the 28nm high performance silicon variant of the Vivante architecture can clock up to 1GHz at full speed, but fall back to 1/64th of this in power saving mode, or roughly 16MHz.
