GeForce GT 240 GDDR5 vs GeForce GTX 860M

Intro

The GeForce GT 240 GDDR5 uses a 40 nm design. nVidia has clocked the core speed at 550 MHz. The GDDR5 RAM works at a speed of 850 MHz on this particular model. It features 96 SPUs as well as 32 TAUs and 8 Rasterization Operator Units.

Compare all of that to the GeForce GTX 860M, which comes with clock speeds of 797 MHz on the GPU, and 1000 MHz on the 4096 MB of GDDR5 memory. It features 1152 SPUs along with 96 TAUs and 16 ROPs.

Memory Bandwidth: Bandwidth is the largest amount of information (counted in MB per second) that can be transported across the external memory interface in a second. It is calculated by multiplying the interface width by its memory speed. If it uses DDR type memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed in one second. This number 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 video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly write to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
