While the memory of HD 6970 2GB runs at an astounding 5.5GHz (effective), the HD 6950 2GB has 5GHz (effective) memory, meaning it has 160GB/sec of memory bandwidth rather than 176GB/sec. The ROPs have seen upgrades too, and both HD 6900-series cards will have 2GB of GDDR5 memory running at comparably high frequencies to give the large amount of memory bandwidth from the 256-bit memory interface. The HD 6950 2GB runs at 800MHz rather than 880MHz. The lesser number of SIMD Engines means there are fewer texture units in the HD 6950 2GB than the HD 6970 2GB as well. However, the HD 6950 2GB has even fewer stream processors, with only 22 SIMD Engines rather than 24, meaning it has a total of 1,408 stream processors. ATI says the new layout, called VLIW4, is 10 per cent faster per mm 2. The Caicos graphics processor is a relatively small chip with a die area of only 67 mm² and 370 million transistors.

Built on the 40 nm process, and based on the Caicos graphics processor, in its Caicos PRO variant, the card supports DirectX 11.2. Featuring 2GB of high-speed GDDR5 memory, the AMD Radeon HD 6900 Series is primed to enable ultra high-res. The Radeon HD 6450 was an entry-level graphics card by AMD, launched on April 7th, 2011. While this means that the HD 6970 2GB has fewer stream processors than the HD 5870 1GB, they’re more capable. The SAPPHIRE HD 6950 is a new SAPPHIRE original model with a special cooler using a new dual fan configuration. Get Immersed with AMD Eyefinity Technology. They’re organised in groups of four, with 16 of these groups per SIMD Engine (or stream processors cluster). Those stream processors have been upgraded, so they’re all capable of the high-precision work that only a fifth of the stream processors of previous generations were able to calculate. AMD Radeon HD 6950 XFX 2GB Edition Performance Review Radeon HD 6950 XFX 2GB Edition is capable of DirectX 11 gaming requirements.

For a start, there’s two entire Front-End Engines, so the Cayman GPU has two triangle setup units, two tessellators and can send twice as much work per clock to the stream processors as previous Radeon GPUs. It is based on the desktop HD 6850 graphics. Click to enlargeWhile the Barts GPU of the HD 6800-series was a bit same-old, same-old, the new Cayman GPU of the HD 6900 is a big change. The AMD Mobility Radeon HD 6950M (or sometimes called ATI Mobility Radeon HD 6950) is a high-end graphics card generally used for big and heavy laptops.
