GeForce 810M vs Radeon R9 380 4G

Intro

Compare that to the Radeon R9 380 4G, which makes use of a 28 nm design. AMD has clocked the core speed at 970 MHz. The GDDR5 memory works at a speed of 1425 MHz on this particular model. It features 1792 SPUs as well as 112 Texture Address Units and 32 Rasterization Operator Units.

GeForce 810M		14400 MB/sec
	Difference: 168000 (1167%)

Texel Rate

The Radeon R9 380 4G is quite a bit (more or less 1740%) more effective at AF than the GeForce 810M. (explain)

Radeon R9 380 4G		108640 Mtexels/sec
GeForce 810M		5904 Mtexels/sec
	Difference: 102736 (1740%)

Pixel Rate

If using a high screen resolution is important to you, then the Radeon R9 380 4G is the winner, by far. (explain)

Radeon R9 380 4G		31040 Mpixels/sec
GeForce 810M		2952 Mpixels/sec
	Difference: 28088 (951%)

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 moved across the external memory interface in one second. It is calculated by multiplying the interface width by the speed of its memory. If it uses DDR type RAM, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied per second. This is worked out by multiplying the total number of texture units by the core clock speed of the chip. The better 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 most pixels the video 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 amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on quite a few 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.
