GeForce 810M vs Radeon R7 M265

Intro

Compare all of that to the Radeon R7 M265, which features core speeds of 725 MHz on the GPU, and 1000 MHz on the 2048 MB of DDR3 RAM. It features 384 SPUs along with 24 Texture Address Units and 8 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The Radeon R7 M265, in theory, should be much faster than the GeForce 810M overall. (explain)

Radeon R7 M265		32000 MB/sec
GeForce 810M		14400 MB/sec
	Difference: 17600 (122%)

Texel Rate

The Radeon R7 M265 is a lot (approximately 195%) more effective at AF than the GeForce 810M. (explain)

Radeon R7 M265		17400 Mtexels/sec
GeForce 810M		5904 Mtexels/sec
	Difference: 11496 (195%)

Pixel Rate

If using a high screen resolution is important to you, then the Radeon R7 M265 is the winner, by far. (explain)

Radeon R7 M265		5800 Mpixels/sec
GeForce 810M		2952 Mpixels/sec
	Difference: 2848 (96%)

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 information (measured in megabytes per second) that can be transferred past the external memory interface within a second. The number is calculated by multiplying the bus width by the speed of its memory. If the card has DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the card's 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 texture map elements (texels) that are processed in one second. This is worked out by multiplying the total texture units of the card by the core speed of the chip. The higher the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum amount of pixels 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 colour ROPs by the the card's clock speed. 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 output rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
