GeForce GT 210 vs GeForce GTS 450

Intro

Compare that to the GeForce GTS 450, which has GPU clock speed of 783 MHz, and 512 MB of GDDR5 RAM set to run at 902 MHz through a 128-bit bus. It also is made up of 192 Stream Processors, 32 Texture Address Units, and 16 ROPs.

GeForce GT 210		4712 Mtexels/sec
	Difference: 20344 (432%)

Pixel Rate

The GeForce GTS 450 should be a lot (about 432%) better at full screen anti-aliasing than the GeForce GT 210, and will be capable of handling higher screen resolutions without losing too much performance. (explain)

GeForce GTS 450		12528 Mpixels/sec
GeForce GT 210		2356 Mpixels/sec
	Difference: 10172 (432%)

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 largest amount of information (counted in MB per second) that can be moved across the external memory interface in one second. The number is worked out by multiplying the bus width by its memory clock speed. If it uses DDR RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
