GeForce GTX 1050 3GB vs GeForce GTX 870M

Intro

The GeForce GTX 1050 3GB has core speeds of 1392 MHz on the GPU, and 1750 MHz on the 3072 MB of GDDR5 memory. It features 768 SPUs as well as 48 Texture Address Units and 24 Rasterization Operator Units.

Compare those specs to the GeForce GTX 870M, which makes use of a 28 nm design. nVidia has clocked the core speed at 941 MHz. The GDDR5 memory is set to run at a speed of 1000 MHz on this particular model. It features 1344 SPUs along with 112 TAUs and 24 Rasterization Operator Units.

Memory Bandwidth: Memory bandwidth is the max amount of information (counted in megabytes per second) that can be transported over the external memory interface within a second. It is worked out by multiplying the card's bus width by the speed of its memory. In the case of DDR memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly write to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
