GeForce GT 450 (OEM) vs GeForce GTX 960M

Intro

The GeForce GT 450 (OEM) comes with a GPU clock speed of 790 MHz, and the 1536 MB of GDDR5 memory is set to run at 1000 MHz through a 192-bit bus. It also is comprised of 144 Stream Processors, 24 TAUs, and 24 Raster Operation Units.

Compare those specifications to the GeForce GTX 960M, which features GPU core speed of 1096 MHz, and 2048 MB of GDDR5 RAM running at 1000 MHz through a 128-bit bus. It also features 640 SPUs, 40 TAUs, and 16 ROPs.

Memory Bandwidth: Memory bandwidth is the max amount of data (in units of MB per second) that can be transferred past the external memory interface within a second. It's calculated by multiplying the bus width by its memory clock speed. If it uses DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied per second. This figure is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The better the texel rate, 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 that the graphics chip can possibly write to its local memory in one 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 filling the screen with pixels (the image). The actual pixel fill rate also depends on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
