GeForce GT 210 vs Radeon HD 6770

Intro

Compare those specifications to the Radeon HD 6770, which comes with core speeds of 900 MHz on the GPU, and 1050 MHz on the 512 MB of GDDR5 memory. It features 800 SPUs as well as 40 TAUs and 16 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 210		31 Watts
Radeon HD 6770		108 Watts
	Difference: 77 Watts (248%)

Memory Bandwidth

Theoretically speaking, the Radeon HD 6770 will be 425% quicker than the GeForce GT 210 overall, because of its higher bandwidth. (explain)

Radeon HD 6770		67200 MB/sec
GeForce GT 210		12800 MB/sec
	Difference: 54400 (425%)

Texel Rate

The Radeon HD 6770 is a lot (about 664%) better at AF than the GeForce GT 210. (explain)

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

Pixel Rate

If using high levels of AA is important to you, then the Radeon HD 6770 is a better choice, and very much so. (explain)

Radeon HD 6770		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: Memory bandwidth is the max amount of information (in units of MB per second) that can be transferred across the external memory interface in a second. The number is calculated by multiplying the card's bus width by its memory clock speed. If it uses DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. 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 texture map elements (texels) that are applied per second. This number is worked out by multiplying the total amount of texture units by the core clock 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 per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly record to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Render Output Units by the the card's clock speed. 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 quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
