There are a few enhancements to the 5700 series including: Thus 67 are essentially the 57 respectively, with label being the main difference.
#AMD RADEON HD 6870 PRO#
Performance is superior to the NVIDIA GTX 550 Ti and Radeon HD 5770, less powerful than the Radeon HD 6850 and close to the GTX 460 768MB and Radeon HD 5830.ĪMD has confirmed that the HD 6700 cards use the Juniper XT and Juniper Pro cores from the HD 5700 series, and therefore they are not formally Northern Islands GPUs. HD 6790 has 800 stream processors at 840 MHz, a 256-bit memory interface and 1 GB GDDR5 DRAM at 1 GHz with maximum power draw of 150W.Barts uses shaders of the same 5-way VLIW architecture as HD 5000 series.

There is one retail product available, the Radeon HD 6790. They have also been upgraded to support the new technologies found in the Northern Islands GPUs such as HDMI 1.4a, UVD3, and stereoscopic 3D.Ĭodenamed Barts LE, the Radeon HD 6790 was released on April 5, 2011. Turks GPUs contain 80 more stream processors and 4 more texture units. The Radeon HD 65 are minor upgrades of their Evergreen counterparts, the HD 55. They were originally released to OEMs only, but later released to retail. The Turks family includes Turks PRO and Turks XT which are marketed as HD 6570 and HD 6670 respectively. Compared to the 5450 it has double the stream processors, GDDR5 support, along with new Northern Island technologies.Ĭodenamed Turks, these entry-level GPUs were released on February 7, 2011. The sole Caicos product, the Radeon HD 6450, aimed to replace the HD 5450. 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.

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. In related news, the Nvidia has also dropped the prices (up to $90) of its performance cards, with the GTX 460 768MB now priced at $170, GTX 460 1GB at $200, and GTX 470 1280MB at $260.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.

This results in smoother transitions between filter levels, while ensuring full performance and angle independence."įull specifications reveal the HD 6800 series falls someway in between the HD 58 series, and after you check them out below, be sure to check out some benchmarks that show it outperforming the 5800 series in some cases. In addition, the GPUs offer improved Anisotropic Filtering via a refined algorithm that addresses visible discontinuities in very noisy textures. "As such, the 6800 lineup is capable of delivering full-scene anti-aliasing that is not limited to polygon edges or alpha-tested surfaces. You ideally want ~16 pixels per polygon, as this facilitates the best balance of image quality and performance." "The 6800 lineup tessellates the right way, as it focuses on the most efficient usage models. An AMD spokesperson commented on the HD 6800 series improved morphological anti-aliasing and anisotropic filtering performance, and stressed on their adaptive tessellation ability that uses only uses high levels on nearer objects that require finer detail, rather than a “brute force approach”.
