AMD has officially confirmed the specifications of the Radeon HD 6000M series of mobile GPUs, ahead of their unveiling at the Consumer Electronics Show (CES) later this week.

Designed to offer manufacturers the full gamut of performance options, the new Radeon series comprises the budget-level Radeon HD 6300M, 6400M, 6500M, the mid-range 6600M, 6700M, and the high-end 6800M and 6900M.

At the bottom end of the range, the Radeon HD 6300M will be clocked between 500MHz and 750MHz, while the DDR3 memory will be clocked between 800 and 900MHz. The chip has 80 stream processors, eight texture units, 16 Z/stencil ROPs and four colour ROPs. At its highest specs, AMD claims that the 6300M offers 120 gigaflops of processing power, throughput of 187.5 million polygons per second and 14.4GB/sec of memory bandwidth.

Stepping up a level, the Radeon HD 6400M clocks in between 480MHz and 800MHz, with DDR3 or GDDR5 memory running between 800 and 900MHz. The chip features 160 stream processors, eight texture units, 16 Z/stencil ROPs and four colour ROPs. According to AMD, performance on the higher-end implementations is rated at 256 gigaflops, 200 million polygons per second, and memory bandwidth of 25.6GB/sec when using GDDR5 memory.

Hitting the mid range, the Radeon HD 6500M will be clocked between 500MHz and 650MHz, with DDR3 or GDDR5 memory running between 800 and 900MHz. This chip has a respectable count of 400 stream processors, 20 texture units, 32 Z/stencil ROPs, and eight colour ROPS. Despite the comparatively low clock speed, the Radeon HD 6500M's extra hardware pushes it past its cheaper brethren. AMD claims that it's capable of pushing out 520 gigaflops and 650 million polygons per second, while the memory bandwidth is 57.6GB/sec when using GDDR5 memory.

The AMD Radeon HD 6600M and 6700M share similar specifications, both featuring clock speeds between 500MHz and 725MHz, and DDR3 or GDDR5 memory clocks speeds between 800MHz and 900MHz. These chips also feature 480 stream processors, 24 texture units, 32 Z/stencil ROPs, and eight colour ROPs. The increase in clock speed over the Radeon HD 6500M, coupled with the slight boost in the number of stream processors, increases the claimed performance to 696 gigaflops and a throughput of 725 million polygons per second, although the memory bandwidth remains unchanged at 57.6GB/sec.

At the higher end of the scale, the Radeon HD 6800M is clocked between 575MHz and 675MHz, while its GDDR5 memory can be clocked between 900MHz to 1000MHz. The chip boasts a massive count of 800 stream processors, 40 texture units, 64 Z/stencil ROPs, and 16 colour ROPs. At the highest specifications, the Radeon HD 6800M offers up to 1,080 gigaflops of processing power, 675 million polygons per second throughput, and up to 64GB/sec memory bandwidth. While the performance for GPGPU tasks is clearly nothing to be sneezed at, the drop in clock speed appears to hurt the raw polygon performance.

Finally, there's the chip that you're going to see in the money-no-object desktop replacement machines; the Radeon HD 6900M. Clocked between 580MHz and 680MHz, and featuring a 900MHz GDDR5 memory clock, the top-end GPU offers 960 stream processors, 48 texture units, 128 Z/stencil ROPs, and 32 colour ROPs. AMD claims that its processing performance can hit 1.3 teraflops in single precision mode, while throughput is rated at 680 million polygons per second, and the memory bandwidth hits a whopping 115.2GB/sec.

All models in the range support DirectX 11 and OpenGL 4.1, and will also include the full range of AMD graphics technologies, including Eye-Definition, Eyefinity, EyeSpeed and HD3D support, along with the company's UVD 2 video playback acceleration technology.

Sadly, while AMD has been happy to give away the technical specifications, there are no models currently on the market to benchmark. With various partner companies expected to launch laptops based on the new 6000M-series at the CES later this week, we hope we won't have to wait long before we can bring you performance figures, as well as the prices.

Do you think that AMD's latest laptop graphics chips sound like winners, or has the company missed a trick? Share your thoughts over in the forums.
