GeForce 810M vs Radeon R7 M260X

Intro

Compare those specifications to the Radeon R7 M260X, which has a clock frequency of 825 MHz and a GDDR5 memory speed of 1000 MHz. It also makes use of a 128-bit memory bus, and uses a 28 nm design. It is made up of 384 SPUs, 24 Texture Address Units, and 8 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon R7 M260X will be 344% faster than the GeForce 810M overall, due to its greater bandwidth. (explain)

Radeon R7 M260X		64000 MB/sec
GeForce 810M		14400 MB/sec
	Difference: 49600 (344%)

Texel Rate

The Radeon R7 M260X should be a lot (approximately 235%) better at anisotropic filtering than the GeForce 810M. (explain)

Radeon R7 M260X		19800 Mtexels/sec
GeForce 810M		5904 Mtexels/sec
	Difference: 13896 (235%)

Pixel Rate

If using a high screen resolution is important to you, then the Radeon R7 M260X is a better choice, and very much so. (explain)

Radeon R7 M260X		6600 Mpixels/sec
GeForce 810M		2952 Mpixels/sec
	Difference: 3648 (124%)

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: Memory bandwidth is the maximum amount of information (counted in megabytes per second) that can be transferred over the external memory interface within a second. It is worked out by multiplying the interface width by its memory clock speed. If the card has DDR memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. 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 can be processed in one second. This figure is worked out by multiplying the total amount of texture units by the core 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 in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly record to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Raster Operations Pipelines 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 fill rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
