GeForce GTX 460 vs GeForce GTX 970M

Intro

The GeForce GTX 460 features a clock speed of 675 MHz and a GDDR5 memory frequency of 900 MHz. It also uses a 192-bit memory bus, and makes use of a 40 nm design. It features 336 SPUs, 56 TAUs, and 24 ROPs.

Compare those specifications to the GeForce GTX 970M, which comes with a clock speed of 924 MHz and a GDDR5 memory frequency of 1000 MHz. It also features a 192-bit memory bus, and uses a 28 nm design. It is made up of 1280 SPUs, 80 TAUs, and 48 Raster Operation Units.

Memory Bandwidth: Memory bandwidth is the largest amount of information (measured in MB per second) that can be transported over the external memory interface in a second. It is calculated by multiplying the interface width by the speed of its memory. If the card has DDR RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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

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