Radeon HD 3470 256MB vs Radeon R7 M260X

Intro

Compare all that to the Radeon R7 M260X, which comes with a GPU core clock speed of 825 MHz, and 2048 MB of GDDR5 RAM running at 1000 MHz through a 128-bit bus. It also is comprised of 384 SPUs, 24 TAUs, and 8 Raster Operation Units.

Radeon HD 3470 256MB		30400 MB/sec
	Difference: 33600 (111%)

Texel Rate

The Radeon R7 M260X will be much (more or less 519%) better at texture filtering than the Radeon HD 3470 256MB. (explain)

Radeon R7 M260X		19800 Mtexels/sec
Radeon HD 3470 256MB		3200 Mtexels/sec
	Difference: 16600 (519%)

Pixel Rate

If using high levels of AA is important to you, then the Radeon R7 M260X is the winner, by far. (explain)

Radeon R7 M260X		6600 Mpixels/sec
Radeon HD 3470 256MB		3200 Mpixels/sec
	Difference: 3400 (106%)

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 MB per second) that can be transported over the external memory interface in one second. It is worked out by multiplying the interface width by its memory speed. If it uses DDR type RAM, 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 AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out 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 fill rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
