GeForce 810M vs Radeon HD 5770

Intro

Compare all that to the Radeon HD 5770, which has core speeds of 850 MHz on the GPU, and 1200 MHz on the 1024 MB of GDDR5 memory. It features 800(160x5) SPUs as well as 40 Texture Address Units and 16 Rasterization Operator Units.

Texel Rate

The Radeon HD 5770 is quite a bit (more or less 476%) faster with regards to anisotropic filtering than the GeForce 810M. (explain)

Radeon HD 5770		34000 Mtexels/sec
GeForce 810M		5904 Mtexels/sec
	Difference: 28096 (476%)

Pixel Rate

The Radeon HD 5770 is quite a bit (approximately 361%) faster with regards to AA than the GeForce 810M, and able to handle higher screen resolutions without losing too much performance. (explain)

Radeon HD 5770		13600 Mpixels/sec
GeForce 810M		2952 Mpixels/sec
	Difference: 10648 (361%)

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 max amount of information (counted in MB per second) that can be transported across the external memory interface in a second. The number is worked out by multiplying the card's bus width by the speed of its memory. If the card has DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly write to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. 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 output rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
