GeForce 920M vs GeForce GT 130

Intro

Compare those specifications to the GeForce GT 130, which features core speeds of 500 MHz on the GPU, and 250 MHz on the 768 MB of DDR2 RAM. It features 48 SPUs along with 24 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the GeForce 920M is 20% quicker than the GeForce GT 130 overall, due to its greater bandwidth. (explain)

GeForce 920M		14400 MB/sec
GeForce GT 130		12000 MB/sec
	Difference: 2400 (20%)

Texel Rate

The GeForce 920M will be a lot (approximately 154%) faster with regards to texture filtering than the GeForce GT 130. (explain)

GeForce 920M		30528 Mtexels/sec
GeForce GT 130		12000 Mtexels/sec
	Difference: 18528 (154%)

Pixel Rate

If using high levels of AA is important to you, then the GeForce GT 130 is superior to the GeForce 920M, not by a very large margin though. (explain)

GeForce GT 130		8000 Mpixels/sec
GeForce 920M		7632 Mpixels/sec
	Difference: 368 (5%)

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.

Price Comparison

Specifications

Memory Bandwidth: Memory bandwidth is the maximum amount of data (in units of megabytes per second) that can be transported over the external memory interface within a second. It's calculated by multiplying the card's interface width by its memory speed. If the card has DDR type RAM, it should 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 AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed per second. This is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The better the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on many 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.
