GeForce GT 240 GDDR5 vs GeForce GTX 650 Ti

Intro

The GeForce GT 240 GDDR5 comes with a core clock frequency of 550 MHz and a GDDR5 memory frequency of 850 MHz. It also features a 128-bit bus, and uses a 40 nm design. It is made up of 96 SPUs, 32 TAUs, and 8 Raster Operation Units.

Compare those specifications to the GeForce GTX 650 Ti, which comes with a core clock speed of 928 MHz and a GDDR5 memory speed of 1350 MHz. It also features a 128-bit memory bus, and uses a 28 nm design. It is comprised of 768 SPUs, 64 Texture Address Units, and 16 ROPs.

Memory Bandwidth: Memory bandwidth is the max amount of information (in units of megabytes per second) that can be transferred over the external memory interface in a second. The number is worked out by multiplying the card's bus width by the speed of its memory. If it uses DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly record to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
