GeForce GTS 450 1GB vs GeForce GTX 860M

Intro

The GeForce GTS 450 1GB features a core clock frequency of 783 MHz and a GDDR5 memory frequency of 902 MHz. It also uses a 128-bit bus, and uses a 40 nm design. It features 192 SPUs, 32 TAUs, and 16 ROPs.

Compare that to the GeForce GTX 860M, which uses a 28 nm design. nVidia has clocked the core speed at 797 MHz. The GDDR5 memory runs at a frequency of 1000 MHz on this particular model. It features 1152 SPUs along with 96 TAUs and 16 ROPs.

Memory Bandwidth: Bandwidth is the maximum amount of information (in units of megabytes per second) that can be transferred past the external memory interface in a second. It is worked out by multiplying the bus width by its memory clock speed. In the case of DDR RAM, it should be multiplied by 2 once again. If it uses 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 number is worked out by multiplying the total texture units of the card 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 processed in a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can 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 sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on lots of 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.
