GeForce GT 240 GDDR5 vs Radeon R7 M260X

Intro

Compare that to the Radeon R7 M260X, which makes use of a 28 nm design. AMD has set the core frequency at 825 MHz. The GDDR5 RAM is set to run at a speed of 1000 MHz on this model. It features 384 SPUs along with 24 Texture Address Units and 8 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically, the Radeon R7 M260X should perform a bit faster than the GeForce GT 240 GDDR5 in general. (explain)

Radeon R7 M260X		64000 MB/sec
GeForce GT 240 GDDR5		54400 MB/sec
	Difference: 9600 (18%)

Texel Rate

The Radeon R7 M260X will be a little bit (more or less 13%) faster with regards to texture filtering than the GeForce GT 240 GDDR5. (explain)

Radeon R7 M260X		19800 Mtexels/sec
GeForce GT 240 GDDR5		17600 Mtexels/sec
	Difference: 2200 (13%)

Pixel Rate

The Radeon R7 M260X will be much (more or less 50%) faster with regards to anti-aliasing than the GeForce GT 240 GDDR5, and also will be able to handle higher screen resolutions more effectively. (explain)

Radeon R7 M260X		6600 Mpixels/sec
GeForce GT 240 GDDR5		4400 Mpixels/sec
	Difference: 2200 (50%)

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 largest amount of data (in units of megabytes per second) that can be moved past the external memory interface within a second. It's worked out by multiplying the card's bus width by its memory speed. If the card has DDR type memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better 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 are applied in one second. This number is calculated by multiplying the total amount of texture units of the card by the core 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 in one second.

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