GeForce GTX 460 1GB vs GeForce GTX 970M

Intro

The GeForce GTX 460 1GB comes with a GPU core clock speed of 675 MHz, and the 1024 MB of GDDR5 memory runs at 900 MHz through a 256-bit bus. It also is comprised of 336 Stream Processors, 56 TAUs, and 32 Raster Operation Units.

Compare all that to the GeForce GTX 970M, which features a core clock speed of 924 MHz and a GDDR5 memory speed of 1000 MHz. It also makes use of a 192-bit memory bus, and uses a 28 nm design. It is comprised of 1280 SPUs, 80 Texture Address Units, and 48 Raster Operation Units.

Memory Bandwidth: Memory bandwidth is the max amount of information (counted in MB per second) that can be transported across the external memory interface in a second. The number is worked out by multiplying the interface width by the speed of its memory. If the card has DDR type RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the better 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 number of texture map elements (texels) that can be applied per second. This is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
