AMD announces Radeon HD 6990M the fastest mobile GPU

AMD's new Radeon HD 6990M is based on the TeraScale 2 unified processor architecture and the Barts GPU core. This is a mobile equivalent to the company's high-end Radeon HD 6990 PCI Express graphics card design and features 1,120 stream processing units, 56 texture units, 128 Z/stencil ROP units, and 32 colour ROP units. AMD has included support for OpenGL 4.1, OpenCL 1.1 and MicroSoft's DirectX 11 and DirectCompute 11. There was no mention of the Thermal Design Point, so it is unclear how much power will be required to run this new chip.

WebGL Security

WebGL pays strong attention to security - just as any web technology should. With growing recognition of WebGL in the press, we thought we would summarize Khronos' work and stance on this important topic.

  1. Khronos agrees that security is a vitally important consideration for any web standard. WebGL was architected with security in mind from the ground up.
  2. All WebGL implementations already necessarily contain safeguards which prevent out-of-range memory accesses during rendering operations and access of uninitialized memory; please see here and here. These safeguards are tested by the WebGL conformance suite.
  3. Defense against denial of service attacks is still evolving in WebGL implementations. Khronos has specified an extension to OpenGL and OpenGL ES, GL_ARB_robustness, designed to prevent denial of service and out-of-range memory access attacks from WebGL content, preventing any possibility of using WebGL to execute malware on a user's machine.
  4. GL_ARB_robustness has already been deployed by some GPU vendors and Khronos expects it to be deployed rapidly by others. Browsers can check for the presence of this extension before enabling WebGL content. This is likely to become the deployment mode for WebGL in the near future.
  5. The ability to incorporate cross-domain images into WebGL scenes provides great utility to developers, but the WebGL working group is considering requiring Cross Origin Resource Sharing (CORS) opt-in or other mechanisms to prevent possible future abuse of this capability.
  6. The WebGL working group has been working closely with the GPU vendors in the Khronos group to make accelerated WebGL implementations secure and WebGL is influencing GPUs to provide even more flexible security options in the future.
  7. There are no known WebGL exploits and Khronos will continue to place close attention to technical and ecosystem opportunities to ensure WebGL is a secure technology that can be used with confidence.

Turning ‘natural interface’ input into a new data standard

Jon Peddie Research has written up a great review of the Khronos Groups new StreamInput API. Kathleen Maher writes "There is a tipping point out there somewhere and it doesn’t seen too far away. The Internet of Things is practically building itself. Khronos’ first role will be to help developers take advantage of sensors for mobile and console devices, but the day is not far off when the applications for sensors broaden further into our everyday lives and capabilities."

Autodesk and Khronos.org were among the exhibitors competing for attention at GDC

GDC was a beehive of activity with companies madly competing for attention. The Khronos Group was no exception, as they had a large presence this year at GDC. GFXSpeak discusses the changing tide. "The mobile gaming market is growing fast, enabled by smart phones and devices that are getting smarter with every turn of the Moore’s Law crank. The new processors including Nvidia’s Tegra, the Imagination-fueled OMAP processors and Intel’s coming Medfield; Freescale, Marvell, and others all do 3D as a matter of course. There’s a sea change coming in the next 24 months as these new processors enable 3D content." Read the complete article at GFX Speak.

WebCL speculations around the net

ConceivablyTech posted a good review of the WebGL 1.0 Spec release news and followed it up with their own speculation on WebCL. "Enabled in a browser, WebCL could open an entirely new world for cloud applications at much higher performance levels. Khronos mentioned image and video processing as well as advanced physics for web games that could come alive through WebCL."

Khronos Group Releases Free COLLADA Conformance Test Suite

The Khronos™ Group today announced that it is making the COLLADA™ 1.4 Conformance Test Suite available free of charge to all developers. COLLADA is an open, XML-based industry standard that enables assets to be freely interchanged between 3D authoring applications which can then be mixed and matched in powerful combinations. The COLLADA test suite is a comprehensive set of over 500 detailed tests and a scripted framework that rigorously exercises applications that import and export COLLADA assets to ensure that they can reliably participate in a COLLADA-based toolchain.
