GeForce GTX 965M vs GeForce GTX 970M

Intro

The GeForce GTX 965M makes use of a 28 nm design. nVidia has clocked the core speed at 944 MHz. The GDDR5 memory is set to run at a frequency of 1000 MHz on this card. It features 1024 SPUs along with 64 TAUs and 32 Rasterization Operator Units.

Compare those specifications to the GeForce GTX 970M, which comes with GPU clock speed of 924 MHz, and 3072 MB of GDDR5 RAM running at 1000 MHz through a 192-bit bus. It also is comprised of 1280 SPUs, 80 TAUs, and 48 ROPs.

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 in one second. The number is worked out by multiplying the card's interface width by its memory clock speed. If the card has DDR memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied per second. This is worked out by multiplying the total number of 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 one second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly write to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of ROPs 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 quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
