GeForce GT 210 vs Radeon HD 6770 1GB

Intro

Compare all that to the Radeon HD 6770 1GB, which comes with GPU clock speed of 900 MHz, and 1024 MB of GDDR5 RAM running at 1050 MHz through a 128-bit bus. It also is comprised of 800 Stream Processors, 40 Texture Address Units, and 16 ROPs.

Texel Rate

The Radeon HD 6770 1GB should be quite a bit (approximately 664%) faster with regards to anisotropic filtering than the GeForce GT 210. (explain)

Radeon HD 6770 1GB		36000 Mtexels/sec
GeForce GT 210		4712 Mtexels/sec
	Difference: 31288 (664%)

Pixel Rate

The Radeon HD 6770 1GB will be a lot (approximately 511%) more effective at anti-aliasing than the GeForce GT 210, and will be able to handle higher resolutions without slowing down too much. (explain)

Radeon HD 6770 1GB		14400 Mpixels/sec
GeForce GT 210		2356 Mpixels/sec
	Difference: 12044 (511%)

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 (counted in MB per second) that can be transported across the external memory interface within a second. It is calculated by multiplying the card's interface 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 higher 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 texture map elements (texels) that can be applied per second. This figure is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The better the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly write to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
