GeForce 930M vs GeForce GT 210

Intro

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

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the GeForce 930M is 13% quicker than the GeForce GT 210 overall, because of its greater bandwidth. (explain)

GeForce 930M		14400 MB/sec
GeForce GT 210		12800 MB/sec
	Difference: 1600 (13%)

Texel Rate

The GeForce 930M should be a lot (approximately 373%) faster with regards to texture filtering than the GeForce GT 210. (explain)

GeForce 930M		22272 Mtexels/sec
GeForce GT 210		4712 Mtexels/sec
	Difference: 17560 (373%)

Pixel Rate

The GeForce 930M is a lot (approximately 215%) more effective at full screen anti-aliasing than the GeForce GT 210, and should be able to handle higher resolutions without losing too much performance. (explain)

GeForce 930M		7424 Mpixels/sec
GeForce GT 210		2356 Mpixels/sec
	Difference: 5068 (215%)

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 max amount of data (in units of MB per second) that can be moved across the external memory interface within a second. It's calculated by multiplying the card's interface width by its memory clock speed. If it uses DDR RAM, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied in one second. This is calculated by multiplying the total amount of texture units by the core 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 processed in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of colour ROPs by the the card's 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 also depends on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
