GeForce GT 240 GDDR5 1GB vs GeForce GTX 295

Intro

The GeForce GT 240 GDDR5 1GB features a GPU clock speed of 550 MHz, and the 1024 MB of GDDR5 RAM is set to run at 850 MHz through a 128-bit bus. It also is made up of 96 Stream Processors, 32 TAUs, and 8 ROPs.

Compare all that to the GeForce GTX 295, which comes with core speeds of 576 MHz on the GPU, and 999 MHz on the 896 MB of GDDR3 RAM. It features 240 SPUs as well as 80 Texture Address Units and 28 Rasterization Operator Units.

GeForce GT 240 GDDR5 1GB 54400 MB/sec
Difference: 169376 (311%)

Texel Rate

The GeForce GTX 295 is much (about 424%) more effective at anisotropic filtering than the GeForce GT 240 GDDR5 1GB. (explain)

GeForce GTX 295 92160 Mtexels/sec
GeForce GT 240 GDDR5 1GB 17600 Mtexels/sec
Difference: 74560 (424%)

Pixel Rate

If using high levels of AA is important to you, then the GeForce GTX 295 is the winner, by a large margin. (explain)

GeForce GTX 295 32256 Mpixels/sec
GeForce GT 240 GDDR5 1GB 4400 Mpixels/sec
Difference: 27856 (633%)

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.

One or more cards in this comparison are multi-core. This means that their bandwidth, texel and pixel rates are theoretically doubled - this does not mean the card will actually perform twice as fast, but only that it should in theory be able to. Actual game benchmarks will give a more accurate idea of what it's capable of.

Memory Bandwidth: Memory bandwidth is the max amount of information (measured in MB per second) that can be transferred over the external memory interface in a second. The number is calculated by multiplying the bus width by its memory speed. In the case of 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 anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied in one second. This number is worked out by multiplying the total amount of 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 processed in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly record to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as 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 bandwidth is, the lower the ability to get to the maximum fill rate.
