GeForce 920M vs GeForce GT 210

Intro

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

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically, the GeForce 920M should perform a bit faster than the GeForce GT 210 in general. (explain)

GeForce 920M		14400 MB/sec
GeForce GT 210		12800 MB/sec
	Difference: 1600 (13%)

Texel Rate

The GeForce 920M should be a lot (more or less 548%) faster with regards to texture filtering than the GeForce GT 210. (explain)

GeForce 920M		30528 Mtexels/sec
GeForce GT 210		4712 Mtexels/sec
	Difference: 25816 (548%)

Pixel Rate

The GeForce 920M should be much (about 224%) more effective at FSAA than the GeForce GT 210, and also should be able to handle higher screen resolutions without losing too much performance. (explain)

GeForce 920M		7632 Mpixels/sec
GeForce GT 210		2356 Mpixels/sec
	Difference: 5276 (224%)

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 maximum amount of data (measured in MB per second) that can be moved over the external memory interface in one second. It is worked out by multiplying the interface width by its memory clock speed. If it uses DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of Raster Operations Pipelines 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 rate also depends on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
