GeForce GTX 460 vs GeForce GTX 970M

Intro

The GeForce GTX 460 comes with a core clock frequency of 675 MHz and a GDDR5 memory frequency of 900 MHz. It also makes use of a 192-bit bus, and uses a 40 nm design. It is comprised of 336 SPUs, 56 Texture Address Units, and 24 ROPs.

Compare that to the GeForce GTX 970M, which has core clock speeds of 924 MHz on the GPU, and 1000 MHz on the 3072 MB of GDDR5 RAM. It features 1280 SPUs along with 80 Texture Address Units and 48 Rasterization Operator Units.

Memory Bandwidth: Bandwidth is the max amount of data (counted in megabytes per second) that can be transported past the external memory interface in one second. It's calculated by multiplying the interface width by the speed of its memory. In the case of DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
