GeForce GT 240 GDDR5 vs GeForce GTX 970M

Intro

The GeForce GT 240 GDDR5 features a clock speed of 550 MHz and a GDDR5 memory speed of 850 MHz. It also uses a 128-bit memory bus, and uses a 40 nm design. It is made up of 96 SPUs, 32 Texture Address Units, and 8 ROPs.

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

Memory Bandwidth: Memory bandwidth is the max amount of information (measured in MB per second) that can be moved across the external memory interface in a second. It's worked out by multiplying the interface width by the speed of its memory. If the card has DDR type RAM, it should be multiplied by 2 once again. If it uses 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, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed in one second. This is worked out by multiplying the total amount of texture units 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 applied per second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). 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 reach the max fill rate.
