Thanks to increases in screen resolutions and ever more complex render pipelines, games and other apps are becoming more and more bandwidth intensive, requiring larger amounts of data to be copied to-and-from memory. Devices are now commonly expected to drive 2K screen resolutions without a hitch; high-end games can have huge geometric complexity, and rendering pipelines typically involve multiple intermediate … Continued

One of the biggest contributors to bandwidth in mobile graphics is the bandwidth linked to texture mapping. This is especially true with increasing screen resolutions, as ever-higher resolution textures are required to maintain image quality, and thus ever more data is being read by the GPU. Reducing texture bandwidth and power with PVRTC and PVRTC2 Imagination recognised this fact early on. PowerVR … Continued

Most modern GPUs don’t like to share data they own – daring to poke the bear will invariably incur a cost. This includes the PowerVR Tile Based Deferred Rendering (TBDR) architecture, which keeps a number of frames in-flight so that vertex, fragment and GPU compute tasks can be dynamically scheduled for execution. For an application to be optimal, a renderer … Continued

After going behind the scenes of Imagination’s latest and greatest PVRTC2 texture compression standard, we now look at how PVRTC works and compare it against other widely texture compression standards available to game developers who want to target the whole range of our PowerVR GPUs, including Series5, Serie5XT and Series6. Textures are ubiquitous in mobile and desktop graphics. They add … Continued

Released at GDC 2012, Imagination’s updated PVRTC2 texture compression technology provides significant enhancements in quality and efficiency offering application developers unrivaled performance while lowering system memory usage and reducing GPU processing overhead for the low power-driven world of mobile graphics. Everything just got better: high contrast textures, NPOT support and sub-texturing Imagination’s PVRTC texture compression format is currently the most … Continued
