GeForce GTX 260 Core 216 vs Radeon R7 240

Intro

Compare those specifications to the Radeon R7 240, which comes with a GPU core clock speed of 730 MHz, and 2048 MB of DDR3 memory running at 900 MHz through a 128-bit bus. It also is made up of 320 SPUs, 20 TAUs, and 8 Raster Operation Units.

In theory, the GeForce GTX 260 Core 216 should be 289% faster than the Radeon R7 240 overall, because of its greater bandwidth. (explain)

GeForce GTX 260 Core 216		111888 MB/sec
Radeon R7 240		28800 MB/sec
	Difference: 83088 (289%)

Texel Rate

The GeForce GTX 260 Core 216 will be quite a bit (more or less 184%) better at AF than the Radeon R7 240. (explain)

GeForce GTX 260 Core 216		41472 Mtexels/sec
Radeon R7 240		14600 Mtexels/sec
	Difference: 26872 (184%)

Pixel Rate

If using high levels of AA is important to you, then the GeForce GTX 260 Core 216 is a better choice, by a large margin. (explain)

GeForce GTX 260 Core 216		16128 Mpixels/sec
Radeon R7 240		5840 Mpixels/sec
	Difference: 10288 (176%)

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 information (measured in megabytes per second) that can be transferred over the external memory interface within a second. It is worked out by multiplying the card's interface width by its memory speed. If the card has DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high 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 of the card 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 per second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly write to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
