GeForce 810M vs Radeon HD 3470 256MB

Intro

Compare all of that to the Radeon HD 3470 256MB, which makes use of a 55 nm design. AMD has clocked the core frequency at 800 MHz. The DDR2 RAM runs at a frequency of 950 MHz on this card. It features 40(8x5) SPUs along with 4 TAUs and 4 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon HD 3470 256MB should be 111% quicker than the GeForce 810M overall, due to its higher data rate. (explain)

Radeon HD 3470 256MB		30400 MB/sec
GeForce 810M		14400 MB/sec
	Difference: 16000 (111%)

Texel Rate

The GeForce 810M should be much (more or less 85%) better at AF than the Radeon HD 3470 256MB. (explain)

GeForce 810M		5904 Mtexels/sec
Radeon HD 3470 256MB		3200 Mtexels/sec
	Difference: 2704 (85%)

Pixel Rate

The Radeon HD 3470 256MB is just a bit (more or less 8%) better at anti-aliasing than the GeForce 810M, and will be able to handle higher resolutions more effectively. (explain)

Radeon HD 3470 256MB		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 largest amount of information (measured in megabytes per second) that can be transported over the external memory interface in one second. It is worked out by multiplying the interface width by its memory speed. If it uses DDR type memory, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This is calculated by multiplying the total number of texture units by the core speed of the chip. The better this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly record to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Raster Operations Pipelines by the clock 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 output rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
