GeForce 825M vs Radeon R7 M260

Intro

Compare that to the Radeon R7 M260, which uses a 28 nm design. AMD has set the core frequency at 715 MHz. The DDR3 memory works at a speed of 1000 MHz on this card. It features 384 SPUs as well as 24 Texture Address Units and 8 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The Radeon R7 M260 should theoretically 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 is quite a bit (about 26%) faster with regards to anisotropic filtering than the GeForce 825M. (explain)

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

Pixel Rate

The GeForce 825M is a small bit (approximately 19%) better at full screen anti-aliasing than the Radeon R7 M260, and will be able to handle higher screen resolutions while still performing well. (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.

Specifications

Memory Bandwidth: Bandwidth is the largest amount of information (in units of MB per second) that can be moved across the external memory interface in one second. The number is worked out by multiplying the card's bus width by the speed of its memory. In the case of DDR type memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, 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 amount of texture map elements (texels) that are processed in one second. This is calculated by multiplying the total number of texture units by the core clock speed of the chip. The better the texel rate, the better the graphics 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 could possibly record to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
