GeForce 825M vs Radeon R7 M260

Intro

Compare those specifications to the Radeon R7 M260, which uses a 28 nm design. AMD has clocked the core frequency at 715 MHz. The DDR3 memory runs at a speed of 1000 MHz on this specific card. It features 384 SPUs along with 24 Texture Address Units and 8 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The Radeon R7 M260 should in theory perform just a bit faster than the GeForce 825M in general. (explain)

Radeon R7 M260		16000 MB/sec
GeForce 825M		14400 MB/sec
	Difference: 1600 (11%)

Texel Rate

The Radeon R7 M260 will be a lot (approximately 26%) better at anisotropic filtering than the GeForce 825M. (explain)

Radeon R7 M260		17160 Mtexels/sec
GeForce 825M		13600 Mtexels/sec
	Difference: 3560 (26%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce 825M is the winner, but it probably won't make a huge difference. (explain)

GeForce 825M		6800 Mpixels/sec
Radeon R7 M260		5720 Mpixels/sec
	Difference: 1080 (19%)

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.

Price Comparison

Specifications

Memory Bandwidth: Bandwidth is the max amount of information (measured in megabytes per second) that can be moved past the external memory interface within a second. It is calculated by multiplying the bus width by the speed of its memory. In the case of DDR type RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly record to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka 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, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
