GeForce GT 210 vs GeForce GTX 260

Intro

Compare all that to the GeForce GTX 260, which uses a 65 nm design. nVidia has set the core speed at 576 MHz. The GDDR3 RAM works at a speed of 999 MHz on this specific model. It features 192 SPUs as well as 64 TAUs and 28 ROPs.

GeForce GT 210		31 Watts
GeForce GTX 260		182 Watts
	Difference: 151 Watts (487%)

Memory Bandwidth

Theoretically, the GeForce GTX 260 should perform quite a bit faster than the GeForce GT 210 in general. (explain)

GeForce GTX 260		111888 MB/sec
GeForce GT 210		12800 MB/sec
	Difference: 99088 (774%)

Texel Rate

The GeForce GTX 260 will be quite a bit (more or less 682%) more effective at texture filtering than the GeForce GT 210. (explain)

GeForce GTX 260		36864 Mtexels/sec
GeForce GT 210		4712 Mtexels/sec
	Difference: 32152 (682%)

Pixel Rate

The GeForce GTX 260 is much (about 585%) more effective at full screen anti-aliasing than the GeForce GT 210, and also capable of handling higher resolutions better. (explain)

GeForce GTX 260		16128 Mpixels/sec
GeForce GT 210		2356 Mpixels/sec
	Difference: 13772 (585%)

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 information (measured in megabytes per second) that can be transferred over the external memory interface in one second. The number is worked out by multiplying the card's interface width by its memory clock speed. In the case of DDR RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed in one second. This figure is calculated by multiplying the total number of texture units of the card 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 processed in a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly write to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
