Codenamed Caicos, it came to market at the same time as the Radeon HD 6500/6600 Turks GPUs. Over the following months, the budget, midrange, and high-end cards were filled into the series.ĪMD released the entry-level Radeon HD 6400 GPU on February 7, 2011. Codenamed ''Northern Islands'', this series was released on Octoafter brief delays. The 6800 series was the first batch of the Radeon 6000 series. Open CL 1.0 to 1.2 are supported for all Chips with Terascale 2 and 3. OpenCL accelerates many scientific Software Packages against CPU up to factor 10 or 100 and more. Unified Video Decoder (UVD3) is present on the die of all products and supported by AMD Catalyst and by the free and open-source graphics device driver. The AMD Eyefinity-branded on- die display controllers were introduced in September 2009 in the Radeon HD 5000 Series and have been present in all products since. Its direct competitor was Nvidia's GeForce 500 Series they were launched approximately a month apart. This also marks the end of the "Mobility Radeon" name in their laptop GPUs, keeping only the "M" suffix in the GPU model number to signify a Mobile variant. The logo for graphics products and technologies also received a minor makeover (using design elements of the 2010 "AMD Vision" logo). Therefore, the AMD brand was used as the replacement. Starting with this family, the former ATI brand was officially discontinued in favor of making a correlation between the graphics products and the AMD branding for computing platforms (the CPUs and chipsets).
Some models are based on TeraScale 2 (VLIW5), some on the new TeraScale 3 (VLIW4) introduced with them. Still, if you're rocking an AMD system then AMD graphics cards make the perfect match.The Northern Islands series is a family of GPUs developed by Advanced Micro Devices (AMD) forming part of its Radeon-brand, based on the 40 nm process. When you factor in an Intel CPU based platform the AMD cards suddenly don't look quite so capable, and the more expensive Nvidia GPU wins the day. It represents a huge step-up in power, even with the weakest of the CPUs, and when compared with the much more expensive GTX 570 that though, is on the AMD side. Word from leading AMD manufacturers suggests we could still see new HD 6950s with the flashing reinstated.Īs a graphics upgrade though, especially on the AMD side of the CPU war, the HD 6950 is definitely the one to aim for. Some recent respins though have come either with the dual BIOS switch disabled, or with lower frame buffers, both of which stop any flashing shenanigans you might wish to perform.įrom a cynical point of view though, you could say it wasn't a coincidence that this happened at the same time AMD launched its multi-GPU HD 6990.
