GeForce GT 210 vs GeForce GT 450 (OEM)

Intro

Compare all that to the GeForce GT 450 (OEM), which has clock speeds of 790 MHz on the GPU, and 1000 MHz on the 1536 MB of GDDR5 memory. It features 144 SPUs as well as 24 Texture Address Units and 24 Rasterization Operator Units.

	Difference: 83200 (650%)

Texel Rate

The GeForce GT 450 (OEM) is much (approximately 302%) faster with regards to AF than the GeForce GT 210. (explain)

GeForce GT 450 (OEM)		18960 Mtexels/sec
GeForce GT 210		4712 Mtexels/sec
	Difference: 14248 (302%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce GT 450 (OEM) is a better choice, and very much so. (explain)

GeForce GT 450 (OEM)		18960 Mpixels/sec
GeForce GT 210		2356 Mpixels/sec
	Difference: 16604 (705%)

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 max amount of information (counted in megabytes per second) that can be moved over the external memory interface in a second. The number is calculated by multiplying the interface width by its memory clock speed. If it uses DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better 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 texture map elements (texels) that are applied per second. This is worked out by multiplying the total amount of texture units by the core speed of the chip. The higher the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly record to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill 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 reach the max fill rate.
