GeForce GT 130 vs GeForce GT 210

Intro

Compare those specifications to the GeForce GT 210, which has a clock speed of 589 MHz and a DDR3 memory frequency of 800 MHz. It also makes use of a 64-bit bus, and makes use of a 40 nm design. It is comprised of 16 SPUs, 8 TAUs, and 4 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 210		31 Watts
GeForce GT 130		75 Watts
	Difference: 44 Watts (142%)

Memory Bandwidth

In theory, the GeForce GT 210 should perform just a bit faster than the GeForce GT 130 in general. (explain)

GeForce GT 210		12800 MB/sec
GeForce GT 130		12000 MB/sec
	Difference: 800 (7%)

Texel Rate

The GeForce GT 130 will be a lot (about 155%) better at AF than the GeForce GT 210. (explain)

GeForce GT 130		12000 Mtexels/sec
GeForce GT 210		4712 Mtexels/sec
	Difference: 7288 (155%)

Pixel Rate

If running with a high resolution is important to you, then the GeForce GT 130 is the winner, by far. (explain)

GeForce GT 130		8000 Mpixels/sec
GeForce GT 210		2356 Mpixels/sec
	Difference: 5644 (240%)

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 (in units of megabytes per second) that can be moved past the external memory interface in one second. The number is worked out by multiplying the bus width by its memory speed. If the card has DDR RAM, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the better 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 number of texture map elements (texels) that are processed in one second. This is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The better this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly write to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as 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 - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
