GeForce 810M vs Radeon R7 250

Intro

Compare those specs to the Radeon R7 250, which comes with 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 TAUs and 8 Rasterization Operator Units.

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

Memory Bandwidth

In theory, the Radeon R7 250 should perform a lot faster than the GeForce 810M in general. (explain)

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

Texel Rate

The Radeon R7 250 is quite a bit (more or less 307%) better at AF than the GeForce 810M. (explain)

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

Pixel Rate

If using high levels of AA is important to you, then the Radeon R7 250 is a better choice, by far. (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 largest amount of data (measured in megabytes per second) that can be transferred over the external memory interface within a second. It is worked out by multiplying the card's interface width by the speed of its memory. If it uses DDR type memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed in one second. This is calculated by multiplying the total number of texture units by the core clock speed of the chip. The better this number, the better the 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 number of pixels that the graphics card can possibly write to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. 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 many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
