GeForce 825M vs Radeon R7 M260

Intro

The GeForce 825M makes use of a 28 nm design. nVidia has clocked the core frequency at 850 MHz. The DDR3 memory runs at a frequency of 900 MHz on this particular model. It features 384 SPUs along with 16 TAUs and 8 Rasterization Operator Units.

Compare those specifications to the Radeon R7 M260, which has a clock frequency of 715 MHz and a DDR3 memory speed of 1000 MHz. It also makes use of a 64-bit memory bus, and uses a 28 nm design. It is comprised of 384 SPUs, 24 Texture Address Units, and 8 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon R7 M260 is 11% quicker than the GeForce 825M in general, due to its greater data rate. (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%) better at AF 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 little bit (more or less 19%) faster with regards to anti-aliasing than the Radeon R7 M260, and will be capable of handling higher screen resolutions more effectively. (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 transferred past the external memory interface in one second. It's calculated by multiplying the card's bus width by its memory speed. If the card has DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly record to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Raster Operations Pipelines 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 quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
