GeForce GTX 1050 vs GeForce GTX 870M

Intro

The GeForce GTX 1050 has core clock speeds of 1354 MHz on the GPU, and 1750 MHz on the 2048 MB of GDDR5 RAM. It features 640 SPUs as well as 40 TAUs and 32 Rasterization Operator Units.

Compare those specs to the GeForce GTX 870M, which comes with a GPU core clock speed of 941 MHz, and 3072 MB of GDDR5 RAM set to run at 1000 MHz through a 192-bit bus. It also is made up of 1344 Stream Processors, 112 Texture Address Units, and 24 Raster Operation Units.

Specifications

Memory Bandwidth: Memory bandwidth is the max amount of information (in units of MB per second) that can be moved past the external memory interface in a second. It's worked out by multiplying the card's bus width by the speed of its memory. In the case of DDR type RAM, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the bandwidth is, 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 applied per second. This is calculated by multiplying the total number of texture units by the core clock speed of the chip. The higher this number, the better the 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 the graphics card could possibly record to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
