GeForce GT 240 GDDR5 1GB vs GeForce GTX 980

Intro

The GeForce GT 240 GDDR5 1GB has a clock speed 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 980, which has GPU core speed of 1126 MHz, and 4096 MB of GDDR5 RAM set to run at 1750 MHz through a 256-bit bus. It also is made up of 2048 Stream Processors, 128 TAUs, and 64 ROPs.

Memory Bandwidth: Memory bandwidth is the maximum amount of information (counted in megabytes per second) that can be transferred across the external memory interface in a second. The number is worked out by multiplying the card's bus width by its memory speed. If it uses DDR RAM, the result should be multiplied by 2 once again. If 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 high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. This number is worked out by multiplying the total texture units of the card by the core speed of the chip. The higher the texel rate, the better the graphics card will be at 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 could possibly write to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
