GeForce 810M vs Radeon R7 250X

Intro

Compare all that to the Radeon R7 250X, which uses a 28 nm design. AMD has clocked the core frequency at 1000 MHz. The GDDR5 memory is set to run at a frequency of 1125 MHz on this specific card. It features 640 SPUs along with 40 TAUs and 16 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

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

Memory Bandwidth

In theory, the Radeon R7 250X should perform quite a bit faster than the GeForce 810M overall. (explain)

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

Texel Rate

The Radeon R7 250X should be much (more or less 578%) faster with regards to anisotropic filtering than the GeForce 810M. (explain)

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

Pixel Rate

If running with a high resolution is important to you, then the Radeon R7 250X is a better choice, by a large margin. (explain)

Radeon R7 250X		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: Bandwidth is the largest amount of data (in units of megabytes per second) that can be transported past the external memory interface within a second. The number is calculated by multiplying the bus width by its memory speed. If it uses DDR memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed in one second. This is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The higher the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly write to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
