This method is mostly used to create engineering samples or reviewer cards that match the target specifications. The second mechanism is the one we are interested in, AMD can configure the VGA BIOS in a way that it disables extra shaders, in addition to the ones disabled via the on-die fuses. The first one relies on fuses inside the GPU, or on the substrate - a mechanism similar to Intel's multiplier locking. When unlocked, these deactivated units become active, resulting in a substantial performance increase.ĪMD has two methods of locking the shader count on all of their recent GPUs.
The picture above shows the disabled HD 6950 shaders in red. Please Digg Reddit this story to spread the word. The HD 6970 has nothing that can be unlocked. This article is to unlock the Radeon HD 6950. Creating new SKUs from the same silicon by locking features has been common practice in the industry since at least the Radeon 9500 in 2002. The model variant a GPU chip becomes is decided after the die is produced, at some point before it is put on the card. Just like on all other similar products, AMD's two Cayman variants, called Cayman Pro and Cayman XT, are based on the exact same GPU silicon. Both cards are based on AMD's new Cayman core which is their first graphics processor to use a VLIW4 shader configuration.
With 25 years of robotic end-effector innovation, ATI’s engineering department, the largest of its kind for a robotic tooling company, is focused on developing cost-effective, state-of-the-art products and solutions.IntroductionA few weeks ago AMD released the Radeon HD 6970 and Radeon HD 6950. Key features include: Excellent repeatability, high rigidity, and a lightweight and compact design. All ATI Tool Changers feature the patented Fail-Safe Locking Mechanism and No-Touch Locking™ technology.ĪTI offers a wide selection of Tool Changer models to cover a variety of applications. For this reason, the ATI Tool Changer has become the number-one Tool Changer of choice around the world. These Tool Changers are designed to function reliably for millions of cycles at rated load while maintaining extremely high repeatability. The new Tool Changer also features internal Lock/Unlock sensing and (5) 3/8 NPT and (4) 1/2 NPT pass-through air connections.ĪTI Robotic Tool Changers provide the flexibility to automatically change end-effectors or other peripheral tooling.
The QC-160 utilizes the same proven Locking Mechanism as the QC-200 Series Tool Changers – exceeding 200 kg robot load specifications. The QC-160 Robotic Tool Changer is a new model that has a high moment capacity in a lightweight and compact package.
