GeForce GTX 650 vs GeForce GTX 960M

Intro

The GeForce GTX 650 makes use of a 28 nm design. nVidia has set the core speed at 1058 MHz. The GDDR5 RAM works at a frequency of 1250 MHz on this card. It features 384 SPUs along with 32 TAUs and 16 Rasterization Operator Units.

Compare all that to the GeForce GTX 960M, which has core speeds of 1096 MHz on the GPU, and 1000 MHz on the 2048 MB of GDDR5 memory. It features 640 SPUs along with 40 TAUs and 16 ROPs.

Memory Bandwidth: Bandwidth is the largest amount of information (counted in MB per second) that can be transported past the external memory interface within a second. The number is worked out by multiplying the card's interface width by the speed of its memory. If the card has DDR type memory, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the card's 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 texture map elements (texels) that can be applied in one second. This figure is worked out 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 handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
