GeForce 810M vs Radeon HD 3470 512MB

Intro

Compare that to the Radeon HD 3470 512MB, which comes with a clock speed of 800 MHz and a GDDR3 memory speed of 950 MHz. It also features a 128-bit bus, and makes use of a 55 nm design. It is comprised of 40(8x5) SPUs, 4 Texture Address Units, and 4 Raster Operation Units.

GeForce 810M		14400 MB/sec
	Difference: 16000 (111%)

Texel Rate

The GeForce 810M will be quite a bit (approximately 85%) more effective at AF than the Radeon HD 3470 512MB. (explain)

GeForce 810M		5904 Mtexels/sec
Radeon HD 3470 512MB		3200 Mtexels/sec
	Difference: 2704 (85%)

Pixel Rate

The Radeon HD 3470 512MB will be a bit (about 8%) more effective at AA than the GeForce 810M, and will be able to handle higher resolutions more effectively. (explain)

Radeon HD 3470 512MB		3200 Mpixels/sec
GeForce 810M		2952 Mpixels/sec
	Difference: 248 (8%)

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 maximum amount of data (counted in MB per second) that can be transferred across the external memory interface in a second. It's calculated by multiplying the bus width by its memory speed. If the card has DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the faster 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 are applied per second. This number is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The better this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly write to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
