GeForce 840M vs GeForce GT 210

Intro

Compare those specs to the GeForce GT 210, which features GPU clock speed of 589 MHz, and 512 MB of DDR3 memory set to run at 800 MHz through a 64-bit bus. It also is made up of 16 Stream Processors, 8 TAUs, and 4 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 840M		30 Watts
GeForce GT 210		31 Watts
	Difference: 1 Watts (3%)

Memory Bandwidth

As far as performance goes, the GeForce 840M should theoretically be much superior to the GeForce GT 210 in general. (explain)

GeForce 840M		16000 MB/sec
GeForce GT 210		12800 MB/sec
	Difference: 3200 (25%)

Texel Rate

The GeForce 840M is a lot (more or less 424%) better at AF than the GeForce GT 210. (explain)

GeForce 840M		24696 Mtexels/sec
GeForce GT 210		4712 Mtexels/sec
	Difference: 19984 (424%)

Pixel Rate

If using high levels of AA is important to you, then the GeForce 840M is the winner, and very much so. (explain)

GeForce 840M		8232 Mpixels/sec
GeForce GT 210		2356 Mpixels/sec
	Difference: 5876 (249%)

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: Memory bandwidth is the maximum amount of data (counted in megabytes per second) that can be moved past the external memory interface in one second. It's worked out by multiplying the card's bus width by the speed of its memory. If the card has DDR type RAM, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, the faster 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 can be applied in one second. This figure is calculated by multiplying the total number of texture units by the core speed of the chip. The better this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly write to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
