GeForce 810M vs Radeon HD 5550

Intro

Compare all that to the Radeon HD 5550, which has a core clock speed of 550 MHz and a DDR2 memory frequency of 400 MHz. It also makes use of a 128-bit bus, and makes use of a 40 nm design. It is made up of 320(64x5) SPUs, 16 Texture Address Units, and 8 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically, the GeForce 810M should perform a small bit faster than the Radeon HD 5550 in general. (explain)

GeForce 810M		14400 MB/sec
Radeon HD 5550		12800 MB/sec
	Difference: 1600 (13%)

Texel Rate

The Radeon HD 5550 will be a lot (approximately 49%) faster with regards to anisotropic filtering than the GeForce 810M. (explain)

Radeon HD 5550		8800 Mtexels/sec
GeForce 810M		5904 Mtexels/sec
	Difference: 2896 (49%)

Pixel Rate

The Radeon HD 5550 is a lot (about 49%) more effective at AA than the GeForce 810M, and will be able to handle higher resolutions without slowing down too much. (explain)

Radeon HD 5550		4400 Mpixels/sec
GeForce 810M		2952 Mpixels/sec
	Difference: 1448 (49%)

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 information (in units of megabytes per second) that can be transferred over the external memory interface within a second. It's worked out by multiplying the bus width by the speed of its memory. In the case of DDR type memory, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed per second. This number is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The higher this number, the better the video card will be at handling 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 chip could possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
