GeForce GT 240 GDDR5 1GB vs Radeon R7 M260X

Intro

Compare those specifications to the Radeon R7 M260X, which makes use of a 28 nm design. AMD has clocked the core frequency at 825 MHz. The GDDR5 RAM is set to run at a speed of 1000 MHz on this specific card. It features 384 SPUs as well as 24 TAUs and 8 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

As far as performance goes, the Radeon R7 M260X should theoretically be a little bit superior to the GeForce GT 240 GDDR5 1GB in general. (explain)

Radeon R7 M260X		64000 MB/sec
GeForce GT 240 GDDR5 1GB		54400 MB/sec
	Difference: 9600 (18%)

Texel Rate

The Radeon R7 M260X will be a small bit (more or less 13%) faster with regards to texture filtering than the GeForce GT 240 GDDR5 1GB. (explain)

Radeon R7 M260X		19800 Mtexels/sec
GeForce GT 240 GDDR5 1GB		17600 Mtexels/sec
	Difference: 2200 (13%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon R7 M260X is superior to the GeForce GT 240 GDDR5 1GB, by a large margin. (explain)

Radeon R7 M260X		6600 Mpixels/sec
GeForce GT 240 GDDR5 1GB		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: Memory bandwidth is the largest amount of information (counted in MB per second) that can be transported past the external memory interface within a second. It's calculated by multiplying the interface width by its memory clock speed. If the card has DDR type RAM, the result should 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 AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
