GeForce GTX 965M vs Geforce GTX 670

Intro

The GeForce GTX 965M features a GPU core speed of 944 MHz, and the 2048 MB of GDDR5 RAM runs at 1000 MHz through a 128-bit bus. It also is comprised of 1024 Stream Processors, 64 TAUs, and 32 Raster Operation Units.

Compare that to the Geforce GTX 670, which comes with a clock speed of 915 MHz and a GDDR5 memory frequency of 1500 MHz. It also features a 256-bit bus, and uses a 28 nm design. It is comprised of 1344 SPUs, 112 Texture Address Units, and 32 Raster Operation Units.

Memory Bandwidth: Bandwidth is the max amount of information (counted in megabytes per second) that can be transferred over the external memory interface in a second. It is calculated by multiplying the bus width by the speed of its memory. If it uses DDR type RAM, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied per second. This number is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the most pixels the video card can possibly record to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
