GeForce 810M vs Radeon R7 250

Intro

Compare that to the Radeon R7 250, which has core clock speeds of 1000 MHz on the GPU, and 1150 MHz on the 1024 MB of GDDR5 memory. It features 384 SPUs along with 24 Texture Address Units and 8 ROPs.

GeForce 810M		15 Watts
Radeon R7 250		65 Watts
	Difference: 50 Watts (333%)

Memory Bandwidth

Theoretically speaking, the Radeon R7 250 will be 411% faster than the GeForce 810M overall, due to its higher bandwidth. (explain)

Radeon R7 250		73600 MB/sec
GeForce 810M		14400 MB/sec
	Difference: 59200 (411%)

Texel Rate

The Radeon R7 250 will be quite a bit (approximately 307%) faster with regards to AF than the GeForce 810M. (explain)

Radeon R7 250		24000 Mtexels/sec
GeForce 810M		5904 Mtexels/sec
	Difference: 18096 (307%)

Pixel Rate

If using a high screen resolution is important to you, then the Radeon R7 250 is the winner, and very much so. (explain)

Radeon R7 250		8000 Mpixels/sec
GeForce 810M		2952 Mpixels/sec
	Difference: 5048 (171%)

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 (measured in megabytes per second) that can be transported over the external memory interface within a second. The number is calculated by multiplying the card's interface width by its memory clock speed. If it uses DDR type RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed per second. This number is worked out by multiplying the total texture units 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 processed per second.

Pixel Rate: Pixel rate is the most pixels the video card can possibly record to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
