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.

SIGGRAPH attendees show high level of interest in OpenCL™ technology

SIGGRAPH 2011 in Vancouver last week had a very high level of interest in OpenCL™ as demonstrated by SIGGRAPH attendees. The Exhibitor Tech Talk on “OpenCL and OpenGL/DirectX interoperability” presented by Olivier Zegdoun of AMD’s ISV Workstation team had seating for over 90 attendees and was standing room only. The OpenCL Birds-of-a-Feather with presentations from AMD, Intel, Nvidia and Codeplay over 200 attendees, and when asked who was already using OpenCL approximately half of the attendees raised their hands.

OpenGL renders Zombies faster than Direct3D

Valve Software has updated their Linux blog to report that the OpenGL version of Left 4 Dead 2 is now running fastest on Linux (315 fps). Surprisingly, given all the attention Valve has paid to Direct3D tuning over the years, even on Windows, the OpenGL version of the game now runs faster than Direct3D (304 fps vs. 270 fps) due to "overhead per batch in Direct3D which does not affect OpenGL on Windows".

Amazon launches new EC2 GPU instances for high-performance 3D Graphics in the cloud

Amazon launched a new type of instance for its EC2 cloud computing platform that is specifically designed for applications that require 3D graphics capabilities. Using these new instances, Amazon argues, its users can now “build high-performance DirectX, OpenGL, CUDA, and OpenCL applications and services without making expensive up-front capital investments.” Amazon is making two of these new GPU instance types available for now. The g2.2xlarge version comes with 15 GB memory, 60 GB of local storage, 26 EC2 Compute Units (that’s an Intel Sandy Bridge processor running at 2.6 GHz) and a single NVIDIA Kepler GK104 graphics card (with 1536 CUDA cores). The larger cg1.4xlarge version comes with 22 GB of memory, 1690 GB of local storage, 33.5 EC2 Compute Units and two NVIDIA Tesla “Fermi” M2050 GPUs.
