GeForce GT 210		12800 MB/sec
	Difference: 9600 (75%)

Texel Rate

The Radeon HD 4650 1GB is quite a bit (about 307%) more effective at texture filtering than the GeForce GT 210. (explain)

Radeon HD 4650 1GB		19200 Mtexels/sec
GeForce GT 210		4712 Mtexels/sec
	Difference: 14488 (307%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon HD 4650 1GB is a better choice, by a large margin. (explain)

Radeon HD 4650 1GB		4800 Mpixels/sec
GeForce GT 210		2356 Mpixels/sec
	Difference: 2444 (104%)

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 transported across the external memory interface in one second. It is worked out by multiplying the card's bus width by its memory clock speed. If the card has DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly write to the 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 clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
