GeForce 810M vs Radeon R7 240

Intro

Compare that to the Radeon R7 240, which comes with a core clock frequency of 730 MHz and a DDR3 memory frequency of 900 MHz. It also makes use of a 128-bit bus, and uses a 28 nm design. It is comprised of 320 SPUs, 20 TAUs, and 8 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 810M		15 Watts
Radeon R7 240		30 Watts
	Difference: 15 Watts (100%)

Memory Bandwidth

The Radeon R7 240 should theoretically perform quite a bit faster than the GeForce 810M overall. (explain)

GeForce 810M		14400 MB/sec
	Difference: 14400 (100%)

Texel Rate

The Radeon R7 240 will be a lot (approximately 147%) more effective at AF than the GeForce 810M. (explain)

Radeon R7 240		14600 Mtexels/sec
GeForce 810M		5904 Mtexels/sec
	Difference: 8696 (147%)

Pixel Rate

The Radeon R7 240 should be quite a bit (about 98%) faster with regards to full screen anti-aliasing than the GeForce 810M, and should be able to handle higher screen resolutions without slowing down too much. (explain)

Radeon R7 240		5840 Mpixels/sec
GeForce 810M		2952 Mpixels/sec
	Difference: 2888 (98%)

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 data (measured in megabytes per second) that can be moved past the external memory interface in a second. The number is calculated by multiplying the bus width by the speed of its memory. In the case of DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This number is calculated by multiplying the total 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 processed in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly write to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel 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 maximum fill rate.
