GeForce GTX 260 vs GeForce GTX 970M

Intro

The GeForce GTX 260 has a clock frequency of 576 MHz and a GDDR3 memory speed of 999 MHz. It also makes use of a 448-bit memory bus, and makes use of a 65 nm design. It is made up of 192 SPUs, 64 Texture Address Units, and 28 Raster Operation Units.

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

Memory Bandwidth: Bandwidth is the largest amount of information (in units of megabytes per second) that can be moved across the external memory interface in one second. It's worked out by multiplying the card's interface width by the speed of its memory. If the card has DDR memory, the result 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 anti-aliasing, High Dynamic Range and higher screen 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 texture units of the card by the core speed of the chip. The higher the texel rate, the better the graphics 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 amount of pixels that the graphics chip could possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
