GeForce GTS 450 1GB vs GeForce GTX 960M

Intro

The GeForce GTS 450 1GB uses a 40 nm design. nVidia has clocked the core frequency at 783 MHz. The GDDR5 RAM is set to run at a frequency of 902 MHz on this model. It features 192 SPUs as well as 32 Texture Address Units and 16 ROPs.

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

Memory Bandwidth: Bandwidth is the max amount of information (counted in megabytes per second) that can be transferred over the external memory interface in one second. It's calculated by multiplying the interface width by its memory speed. If it uses DDR type memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels the video card could possibly write to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of colour ROPs by the the core 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 output rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
