GeForce GTX 460 vs Radeon HD 6850
Intro
The GeForce GTX 460 uses a 40 nm design. nVidia has set the core frequency at 675 MHz. The GDDR5 memory is set to run at a frequency of 900 MHz on this model. It features 336 SPUs as well as 56 TAUs and 24 ROPs.Compare those specifications to the Radeon HD 6850, which makes use of a 40 nm design. AMD has clocked the core speed at 775 MHz. The GDDR5 memory is set to run at a frequency of 1000 MHz on this specific card. It features 960 SPUs along with 48 Texture Address Units and 32 Rasterization Operator Units.

Memory Bandwidth: Memory bandwidth is the largest amount of information (measured in megabytes per second) that can be transported over the external memory interface in one second. It's calculated by multiplying the card's bus width by its memory clock speed. In the case of DDR memory, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied per second. This figure is calculated by multiplying the total texture units of the card by the core speed of the chip. The higher this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.
Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly write to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.

This is a little lopsided as the evga version of 460 has 192bit and 823 core clock and has 32 rop's which mean it would be incredibility close with just a little more memory bandwidth with 6850.
