GeForce 825M vs Radeon R7 M360

Intro

Compare all that to the Radeon R7 M360, which has a GPU core clock speed of 1125 MHz, and 2048 MB of DDR3 memory running at 1000 MHz through a 64-bit bus. It also features 384 Stream Processors, 24 TAUs, and 8 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon R7 M360 is 11% faster than the GeForce 825M in general, because of its greater bandwidth. (explain)

Radeon R7 M360		16000 MB/sec
GeForce 825M		14400 MB/sec
	Difference: 1600 (11%)

Texel Rate

The Radeon R7 M360 will be much (approximately 99%) better at AF than the GeForce 825M. (explain)

Radeon R7 M360		27000 Mtexels/sec
GeForce 825M		13600 Mtexels/sec
	Difference: 13400 (99%)

Pixel Rate

The Radeon R7 M360 will be a lot (about 32%) better at AA than the GeForce 825M, and capable of handling higher screen resolutions without slowing down too much. (explain)

Radeon R7 M360		9000 Mpixels/sec
GeForce 825M		6800 Mpixels/sec
	Difference: 2200 (32%)

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 max amount of data (counted in megabytes per second) that can be transferred across the external memory interface within a second. It's worked out by multiplying the bus width by its memory clock speed. If it uses DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly write to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
