GeForce GTX 965M vs GeForce GTX 970M

Intro

The GeForce GTX 965M has a GPU core speed of 944 MHz, and the 2048 MB of GDDR5 RAM is set to run at 1000 MHz through a 128-bit bus. It also is made up of 1024 Stream Processors, 64 Texture Address Units, and 32 ROPs.

Compare all of that 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 comprised of 1280 Stream Processors, 80 Texture Address Units, and 48 Raster Operation Units.

Memory Bandwidth: Memory bandwidth is the maximum amount of information (in units of MB per second) that can be transferred past the external memory interface within a second. The number is calculated by multiplying the interface width by its memory clock speed. If the card has DDR type RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. This figure is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The higher this number, 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 number of pixels the video card can possibly write to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel 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 get to the max fill rate.
