GeForce GTX 460 vs Geforce GTX 670

Intro

The GeForce GTX 460 makes use of a 40 nm design. nVidia has clocked the core speed at 675 MHz. The GDDR5 memory works at a speed of 900 MHz on this particular model. It features 336 SPUs along with 56 TAUs and 24 Rasterization Operator Units.

Compare that to the Geforce GTX 670, which comes with a clock speed of 915 MHz and a GDDR5 memory frequency of 1500 MHz. It also uses a 256-bit memory bus, and uses a 28 nm design. It is comprised of 1344 SPUs, 112 TAUs, and 32 ROPs.

Memory Bandwidth: Memory bandwidth is the largest amount of information (counted in megabytes per second) that can be moved across the external memory interface within a second. The number is calculated by multiplying the card's bus width by its memory clock speed. If it uses DDR type memory, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. This is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The better the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly write to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
