AMD Radeon HD 7970 - worlds first 28nm GPU - OpenCL and OpenGL 4.2

AMD is using the Taiwan Semiconductor Manufacturing Companies new 28nm manufacturing process to build the new high-end Radeon HD 7970 GPU. The HD 7970 sports 4.3 billion transistors in a 365mm2 die. The 7970 supports OpenCL and OpenGL 4.2. It is assembled from 32 GCN compute units, which translates to 2,048 stream processors, each based on AMD’s new SIMD-plus-scalar architecture. As well, the 7970 includes 768KB of L2 cache and eight render back-ends, features a 384-bit interface to 3GB GDDR5 memory and a PCIe 3.0 interface. The GPU is capable of peak throughput of 264GB/s.

MaximumPC publishes OpenCL and WebCL article

MaximumPC has published a brief history and review of OpenCL and WebCL in their January 2012 print magazine. A brief excerpt from the article "Support for OpenCL has been quite strong. AMD is so enamored of OpenCL that it dropped its ATI Stream SDK in favor of a new Accelerated Parallel Processing SDK, which exclusively supports OpenCL. OpenCL has also come to the web. A variant of OpenCL, called WebCL, is in the prototype stage for web browsers, which allows JavaScript to call OpenCL code. This means you may one day run GPU compute code inside your browser."

WebGL Joint And Object Framework released

The Joint And Object (JOA) Framework is a set of javascript templates and a "class" so that beginners can make use of this technology without having to learn the lower level WebGL stuff. The JOA Framework is a combination of a template, support files, user data file, example files and manual. The template file and support files are all modified or unmodified versions of the files used in the WebGL tutorials on LearningWebGL.
