GeForce 825M vs Radeon R7 M260

Intro

The GeForce 825M features a GPU core speed of 850 MHz, and the 2048 MB of DDR3 memory runs at 900 MHz through a 64-bit bus. It also is comprised of 384 Stream Processors, 16 Texture Address Units, and 8 Raster Operation Units.

Compare all of that to the Radeon R7 M260, which features GPU core speed of 715 MHz, and 2048 MB of DDR3 memory set to run at 1000 MHz through a 64-bit bus. It also is made up of 384 SPUs, 24 Texture Address Units, and 8 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

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

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

Texel Rate

The Radeon R7 M260 will be much (more or less 26%) faster with regards to texture filtering than the GeForce 825M. (explain)

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

Pixel Rate

If using high levels of AA is important to you, then the GeForce 825M is superior to the Radeon R7 M260, though not by far. (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.

Memory Bandwidth: Bandwidth is the maximum amount of data (counted in megabytes per second) that can be moved past the external memory interface within a second. It is worked out by multiplying the card's bus width by its memory speed. In the case of DDR memory, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly write to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
