Compare any two graphics cards:

GeForce GTX 650 Ti 2GB vs GeForce GTX 970M

Intro

The GeForce GTX 650 Ti 2GB features a clock frequency of 928 MHz and a GDDR5 memory speed of 1350 MHz. It also features a 128-bit memory bus, and uses a 28 nm design. It features 768 SPUs, 64 Texture Address Units, and 16 Raster Operation Units.

Compare those specifications to the GeForce GTX 970M, which has GPU core speed of 924 MHz, and 3072 MB of GDDR5 memory set to run at 1000 MHz through a 192-bit bus. It also is made up of 1280 SPUs, 80 Texture Address Units, and 48 ROPs.

Memory Bandwidth: Bandwidth is the maximum amount of information (measured in megabytes per second) that can be transported over the external memory interface within a second. It's calculated by multiplying the card's interface width by the speed of its memory. If it uses DDR type memory, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the card's 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 texture map elements (texels) that are applied per second. This is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The better this number, the better the card will be at handling 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 the video card could possibly record to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
