GeForce 810M vs Radeon R9 290

Intro

Compare those specs to the Radeon R9 290, which comes with a clock speed of 800 MHz and a GDDR5 memory speed of 1250 MHz. It also makes use of a 512-bit memory bus, and makes use of a 28 nm design. It is made up of 2560 SPUs, 160 TAUs, and 64 Raster Operation Units.

GeForce 810M		15 Watts
Radeon R9 290		300 Watts
	Difference: 285 Watts (1900%)

Memory Bandwidth

The Radeon R9 290, in theory, should be quite a bit faster than the GeForce 810M overall. (explain)

Radeon R9 290		320000 MB/sec
GeForce 810M		14400 MB/sec
	Difference: 305600 (2122%)

Texel Rate

The Radeon R9 290 is much (more or less 2068%) better at texture filtering than the GeForce 810M. (explain)

Radeon R9 290		128000 Mtexels/sec
GeForce 810M		5904 Mtexels/sec
	Difference: 122096 (2068%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon R9 290 is superior to the GeForce 810M, by a large margin. (explain)

Radeon R9 290		51200 Mpixels/sec
GeForce 810M		2952 Mpixels/sec
	Difference: 48248 (1634%)

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 data (in units of MB per second) that can be transferred across the external memory interface in one second. The number is calculated by multiplying the card's interface width by its memory speed. In the case of DDR memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed per second. This is calculated by multiplying the total texture units by the core 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 in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
