GeForce GT 240 GDDR5 vs Radeon R7 M260

Intro

Compare all that to the Radeon R7 M260, which features a clock frequency of 715 MHz and a DDR3 memory speed of 1000 MHz. It also features a 64-bit bus, and makes use of a 28 nm design. It is made up of 384 SPUs, 24 TAUs, and 8 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the GeForce GT 240 GDDR5 will be 240% quicker than the Radeon R7 M260 in general, because of its higher data rate. (explain)

GeForce GT 240 GDDR5		54400 MB/sec
Radeon R7 M260		16000 MB/sec
	Difference: 38400 (240%)

Texel Rate

The GeForce GT 240 GDDR5 will be a little bit (approximately 3%) better at texture filtering than the Radeon R7 M260. (explain)

GeForce GT 240 GDDR5		17600 Mtexels/sec
Radeon R7 M260		17160 Mtexels/sec
	Difference: 440 (3%)

Pixel Rate

The Radeon R7 M260 is a lot (more or less 30%) faster with regards to anti-aliasing than the GeForce GT 240 GDDR5, and also will be able to handle higher resolutions more effectively. (explain)

Radeon R7 M260		5720 Mpixels/sec
GeForce GT 240 GDDR5		4400 Mpixels/sec
	Difference: 1320 (30%)

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 max amount of information (counted in megabytes per second) that can be transported across the external memory interface within a second. It's worked out by multiplying the interface width by its memory speed. If it uses DDR type memory, it 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 anti-aliasing, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as 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 of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
