GeForce 8500 GT vs GeForce GT 210

Intro

Compare all that to the GeForce GT 210, which comes with a clock frequency of 589 MHz and a DDR3 memory speed of 800 MHz. It also uses a 64-bit bus, and makes use of a 40 nm design. It is comprised of 16 SPUs, 8 Texture Address Units, and 4 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 210		31 Watts
GeForce 8500 GT		45 Watts
	Difference: 14 Watts (45%)

Memory Bandwidth

Both cards have the exact same memory bandwidth, so theoretically they should have identical performance. (explain)

Texel Rate

The GeForce GT 210 will be much (about 31%) better at texture filtering than the GeForce 8500 GT. (explain)

GeForce GT 210		4712 Mtexels/sec
GeForce 8500 GT		3600 Mtexels/sec
	Difference: 1112 (31%)

Pixel Rate

If using a high resolution is important to you, then the GeForce GT 210 is superior to the GeForce 8500 GT, by far. (explain)

GeForce GT 210		2356 Mpixels/sec
GeForce 8500 GT		1800 Mpixels/sec
	Difference: 556 (31%)

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 largest amount of data (measured in MB per second) that can be moved past the external memory interface within a second. It's calculated by multiplying the card's bus width by its memory clock speed. If the card has DDR type RAM, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied per second. This figure is worked out by multiplying the total amount 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 handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
