GeForce GTX 1050 3GB vs GeForce GTX 870M

Intro

The GeForce GTX 1050 3GB comes with a clock frequency of 1392 MHz and a GDDR5 memory speed of 1750 MHz. It also makes use of a 96-bit bus, and makes use of a 14 nm design. It is made up of 768 SPUs, 48 TAUs, and 24 ROPs.

Compare all that to the GeForce GTX 870M, which has GPU clock speed of 941 MHz, and 3072 MB of GDDR5 RAM running at 1000 MHz through a 192-bit bus. It also is comprised of 1344 SPUs, 112 Texture Address Units, and 24 Raster Operation Units.

Memory Bandwidth: Bandwidth is the max amount of data (in units of MB per second) that can be transported across the external memory interface within a second. The number is worked out by multiplying the bus width by its memory clock speed. If it uses DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the card's 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 texture map elements (texels) that can be processed in one second. This number is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better the texel rate, the better the graphics card will be at handling 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 can possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate 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 filling the screen with pixels (the image). The actual pixel rate also depends on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
