GeForce GT 240 GDDR5 vs GeForce GTX 860M

Intro

The GeForce GT 240 GDDR5 has a core clock frequency of 550 MHz and a GDDR5 memory frequency of 850 MHz. It also uses a 128-bit bus, and makes use of a 40 nm design. It is comprised of 96 SPUs, 32 TAUs, and 8 ROPs.

Compare those specs to the GeForce GTX 860M, which makes use of a 28 nm design. nVidia has set the core frequency at 797 MHz. The GDDR5 memory runs at a frequency of 1000 MHz on this specific card. It features 1152 SPUs as well as 96 TAUs and 16 Rasterization Operator Units.

Memory Bandwidth: Memory bandwidth is the largest amount of information (in units of megabytes per second) that can be moved over the external memory interface within a second. It is calculated by multiplying the card's bus width by the speed of its memory. If it uses DDR memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. This is worked out by multiplying the total texture units by the core clock speed of the chip. The higher this number, 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 the graphics card can possibly record to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
