GeForce GT 210 vs GeForce GT 320

Intro

Compare those specs to the GeForce GT 320, which features GPU clock speed of 540 MHz, and 1024 MB of GDDR3 memory running at 790 MHz through a 128-bit bus. It also is comprised of 72 Stream Processors, 24 Texture Address Units, and 8 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 210		31 Watts
GeForce GT 320		43 Watts
	Difference: 12 Watts (39%)

Memory Bandwidth

The GeForce GT 320 should theoretically be a lot faster than the GeForce GT 210 in general. (explain)

GeForce GT 320		25280 MB/sec
GeForce GT 210		12800 MB/sec
	Difference: 12480 (98%)

Texel Rate

The GeForce GT 320 is much (approximately 175%) more effective at AF than the GeForce GT 210. (explain)

GeForce GT 320		12960 Mtexels/sec
GeForce GT 210		4712 Mtexels/sec
	Difference: 8248 (175%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce GT 320 is the winner, by far. (explain)

GeForce GT 320		4320 Mpixels/sec
GeForce GT 210		2356 Mpixels/sec
	Difference: 1964 (83%)

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 data (measured in MB per second) that can be transported past the external memory interface within a second. It's calculated by multiplying the card's interface width by its memory clock speed. If the card has DDR type memory, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied per second. This number 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 graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly write to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Render Output Units by the the core 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 many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
