GeForce 810M vs Radeon R7 M260X

Intro

Compare those specifications to the Radeon R7 M260X, which has GPU clock speed of 825 MHz, and 2048 MB of GDDR5 memory running at 1000 MHz through a 128-bit bus. It also 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% quicker than the GeForce 810M overall, due to its higher data rate. (explain)

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

Texel Rate

The Radeon R7 M260X should be quite a bit (more or less 235%) faster with regards to texture filtering than the GeForce 810M. (explain)

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

Pixel Rate

The Radeon R7 M260X should be a lot (about 124%) better at anti-aliasing than the GeForce 810M, and also capable of handling higher screen resolutions while still performing well. (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 max amount of data (in units of megabytes per second) that can be transferred over the external memory interface in one second. The number is worked out by multiplying the card's interface width by its memory clock speed. If it uses DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied in one 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 this number, the better the video 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 maximum number of pixels the graphics card can possibly write to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
