GeForce GT 440 1.5GB vs GeForce GTX 860M

Intro

The GeForce GT 440 1.5GB has core clock speeds of 594 MHz on the GPU, and 900 MHz on the 1536 MB of GDDR3 RAM. It features 144 SPUs as well as 24 TAUs and 24 Rasterization Operator Units.

Compare that to the GeForce GTX 860M, which uses a 28 nm design. nVidia has clocked the core frequency at 797 MHz. The GDDR5 RAM is set to run at a speed of 1000 MHz on this specific model. It features 1152 SPUs along with 96 Texture Address Units and 16 ROPs.

Memory Bandwidth: Memory bandwidth is the max amount of data (in units of MB per second) that can be transported past the external memory interface in one second. The number is calculated by multiplying the card's interface width by its memory speed. If it uses DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster 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 are applied per second. This number is worked out by multiplying the total amount of texture units 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 a second.

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly write 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 the core 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 fill rate is also dependant on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
