GeForce GT 240 GDDR5 1GB vs Geforce GTX 760

Intro

Compare those specs to the Geforce GTX 760, which uses a 28 nm design. nVidia has set the core speed at 980 MHz. The GDDR5 memory runs at a frequency of 1502 MHz on this particular card. It features 1152 SPUs as well as 96 Texture Address Units and 32 ROPs.

	Difference: 137856 (253%)

Texel Rate

The Geforce GTX 760 should be a lot (approximately 435%) more effective at AF than the GeForce GT 240 GDDR5 1GB. (explain)

Geforce GTX 760		94080 Mtexels/sec
GeForce GT 240 GDDR5 1GB		17600 Mtexels/sec
	Difference: 76480 (435%)

Pixel Rate

If running with a high resolution is important to you, then the Geforce GTX 760 is a better choice, and very much so. (explain)

Geforce GTX 760		31360 Mpixels/sec
GeForce GT 240 GDDR5 1GB		4400 Mpixels/sec
	Difference: 26960 (613%)

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.

Specifications

Memory Bandwidth: Memory bandwidth is the maximum amount of information (counted in MB per second) that can be transported past the external memory interface in one second. It is calculated by multiplying the bus width by its memory clock speed. In the case of DDR type memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed per second. This figure is worked out by multiplying the total number of texture units by the core clock 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 applied per second.

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly write to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill 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.
