GeForce GTS 250 1GB vs GeForce GTX 860M

Intro

The GeForce GTS 250 1GB makes use of a 65/55 nm design. nVidia has clocked the core speed at 738 MHz. The GDDR3 memory works at a frequency of 1100 MHz on this card. It features 128 SPUs along with 64 TAUs and 16 ROPs.

Compare those specifications to the GeForce GTX 860M, which comes with a GPU core clock speed of 797 MHz, and 4096 MB of GDDR5 memory set to run at 1000 MHz through a 128-bit bus. It also is made up of 1152 Stream Processors, 96 TAUs, and 16 ROPs.

Memory Bandwidth: Bandwidth is the max amount of information (in units of MB per second) that can be transported across the external memory interface in a second. It is calculated by multiplying the card's bus width by its memory clock speed. If the card has DDR RAM, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the card's 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 amount of texture map elements (texels) that are applied in one second. This number is calculated by multiplying the total amount of texture units by the core 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 processed in a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
