GeForce GT 240 GDDR5 vs GeForce GTX 750 Ti

Intro

Compare all of that to the GeForce GTX 750 Ti, which features a clock speed of 1020 MHz and a GDDR5 memory frequency of 1350 MHz. It also features a 128-bit bus, and uses a 28 nm design. It features 640 SPUs, 40 Texture Address Units, and 16 Raster Operation Units.

GeForce GT 240 GDDR5		54400 MB/sec
	Difference: 32000 (59%)

Texel Rate

The GeForce GTX 750 Ti will be much (approximately 132%) better at AF than the GeForce GT 240 GDDR5. (explain)

GeForce GTX 750 Ti		40800 Mtexels/sec
GeForce GT 240 GDDR5		17600 Mtexels/sec
	Difference: 23200 (132%)

Pixel Rate

The GeForce GTX 750 Ti should be quite a bit (approximately 271%) better at AA than the GeForce GT 240 GDDR5, and also should be able to handle higher screen resolutions while still performing well. (explain)

GeForce GTX 750 Ti		16320 Mpixels/sec
GeForce GT 240 GDDR5		4400 Mpixels/sec
	Difference: 11920 (271%)

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: Bandwidth is the maximum amount of data (in units of megabytes per second) that can be moved over the external memory interface in a second. It is calculated by multiplying the card's interface width by its memory speed. In the case of DDR memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

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