GeForce GT 240 GDDR5 vs GeForce GTX 965M

Intro

The GeForce GT 240 GDDR5 features a GPU core clock speed of 550 MHz, and the 512 MB of GDDR5 RAM runs at 850 MHz through a 128-bit bus. It also is made up of 96 SPUs, 32 TAUs, and 8 Raster Operation Units.

Compare those specs to the GeForce GTX 965M, which makes use of a 28 nm design. nVidia has set the core speed at 944 MHz. The GDDR5 memory runs at a speed of 1000 MHz on this specific card. It features 1024 SPUs as well as 64 TAUs and 32 Rasterization Operator Units.

Memory Bandwidth: Memory bandwidth is the largest amount of data (counted in megabytes per second) that can be transported across the external memory interface within a second. It's calculated by multiplying the interface width by the speed of its memory. In the case of DDR type memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied per second. This 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 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 most pixels the video card could possibly write to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
