GeForce GTS 450 vs GeForce GTX 860M

Intro

The GeForce GTS 450 features a GPU core clock speed of 783 MHz, and the 512 MB of GDDR5 memory is set to run at 902 MHz through a 128-bit bus. It also is comprised of 192 SPUs, 32 TAUs, and 16 Raster Operation Units.

Compare all that to the GeForce GTX 860M, which comes with core speeds of 797 MHz on the GPU, and 1000 MHz on the 4096 MB of GDDR5 RAM. It features 1152 SPUs along with 96 TAUs and 16 Rasterization Operator Units.

Memory Bandwidth: Memory bandwidth is the largest amount of information (measured in MB per second) that can be transported past the external memory interface in a second. It's worked out by multiplying the card's bus width by its memory speed. If it uses DDR type memory, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly record to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called 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, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
