GeForce 810M vs Radeon R7 260X

Intro

Compare those specifications to the Radeon R7 260X, which comes with a core clock frequency of 1100 MHz and a GDDR5 memory speed of 1625 MHz. It also features a 128-bit memory bus, and makes use of a 28 nm design. It is made up of 896 SPUs, 56 TAUs, and 16 ROPs.

GeForce 810M		15 Watts
Radeon R7 260X		115 Watts
	Difference: 100 Watts (667%)

Memory Bandwidth

Performance-wise, the Radeon R7 260X should in theory be quite a bit superior to the GeForce 810M in general. (explain)

Radeon R7 260X		104000 MB/sec
GeForce 810M		14400 MB/sec
	Difference: 89600 (622%)

Texel Rate

The Radeon R7 260X will be much (more or less 943%) faster with regards to anisotropic filtering than the GeForce 810M. (explain)

Radeon R7 260X		61600 Mtexels/sec
GeForce 810M		5904 Mtexels/sec
	Difference: 55696 (943%)

Pixel Rate

If running with a high screen resolution is important to you, then the Radeon R7 260X is the winner, by far. (explain)

Radeon R7 260X		17600 Mpixels/sec
GeForce 810M		2952 Mpixels/sec
	Difference: 14648 (496%)

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 information (in units of megabytes per second) that can be moved past the external memory interface within a second. The number is worked out by multiplying the card's bus width by its memory speed. In the case of DDR type memory, it should be multiplied by 2 once again. If it uses 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 processed in one second. This figure 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 card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly record to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on lots of 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.
