GeForce GT 240 GDDR5 1GB vs GeForce GTX 980

Intro

The GeForce GT 240 GDDR5 1GB has a 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 Texture Address Units, and 8 Raster Operation Units.

Compare those specifications to the GeForce GTX 980, which features core clock speeds of 1126 MHz on the GPU, and 1750 MHz on the 4096 MB of GDDR5 memory. It features 2048 SPUs along with 128 Texture Address Units and 64 ROPs.

GeForce GT 240 GDDR5 1GB 54400 MB/sec
Difference: 169600 (312%)

Texel Rate

The GeForce GTX 980 should be quite a bit (more or less 719%) faster with regards to texture filtering than the GeForce GT 240 GDDR5 1GB. (explain)

GeForce GTX 980 144128 Mtexels/sec
GeForce GT 240 GDDR5 1GB 17600 Mtexels/sec
Difference: 126528 (719%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce GTX 980 is a better choice, and very much so. (explain)

GeForce GTX 980 72064 Mpixels/sec
GeForce GT 240 GDDR5 1GB 4400 Mpixels/sec
Difference: 67664 (1538%)

Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.

Memory Bandwidth: Memory bandwidth is the maximum amount of data (measured in megabytes per second) that can be transferred over the external memory interface within a second. The number is worked out by multiplying the card's bus width by its memory speed. If the card has DDR RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied per second. This figure is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The higher 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 number of pixels the graphics card can possibly write to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs by the the core speed of the card. 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 lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
