GeForce 810M vs Radeon R7 250X 2GB

Intro

Compare that to the Radeon R7 250X 2GB, which has GPU clock speed of 1000 MHz, and 2048 MB of GDDR5 RAM set to run at 1125 MHz through a 128-bit bus. It also features 640 Stream Processors, 40 TAUs, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 810M		15 Watts
Radeon R7 250X 2GB		95 Watts
	Difference: 80 Watts (533%)

Memory Bandwidth

The Radeon R7 250X 2GB should in theory be much faster than the GeForce 810M in general. (explain)

Radeon R7 250X 2GB		72000 MB/sec
GeForce 810M		14400 MB/sec
	Difference: 57600 (400%)

Texel Rate

The Radeon R7 250X 2GB is quite a bit (approximately 578%) more effective at texture filtering than the GeForce 810M. (explain)

Radeon R7 250X 2GB		40000 Mtexels/sec
GeForce 810M		5904 Mtexels/sec
	Difference: 34096 (578%)

Pixel Rate

If using high levels of AA is important to you, then the Radeon R7 250X 2GB is a better choice, and very much so. (explain)

Radeon R7 250X 2GB		16000 Mpixels/sec
GeForce 810M		2952 Mpixels/sec
	Difference: 13048 (442%)

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 (measured in 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 bus width by its memory clock speed. If it uses DDR type memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied in one second. This number is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The better this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that 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 number of Raster Operations Pipelines by the the core 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 is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
