GeForce 8300 GS (OEM) vs GeForce 920M

Intro

Compare those specifications to the GeForce 920M, which comes with a GPU core clock speed of 954 MHz, and 2048 MB of DDR3 memory running at 900 MHz through a 64-bit bus. It also features 384 Stream Processors, 32 TAUs, and 8 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Performance-wise, the GeForce 920M should in theory be much better than the GeForce 8300 GS (OEM) overall. (explain)

GeForce 920M		14400 MB/sec
GeForce 8300 GS (OEM)		6400 MB/sec
	Difference: 8000 (125%)

Texel Rate

The GeForce 920M is much (approximately 1596%) better at anisotropic filtering than the GeForce 8300 GS (OEM). (explain)

GeForce 920M		30528 Mtexels/sec
GeForce 8300 GS (OEM)		1800 Mtexels/sec
	Difference: 28728 (1596%)

Pixel Rate

The GeForce 920M is much (more or less 748%) faster with regards to AA than the GeForce 8300 GS (OEM), and also should be capable of handling higher resolutions without slowing down too much. (explain)

GeForce 920M		7632 Mpixels/sec
GeForce 8300 GS (OEM)		900 Mpixels/sec
	Difference: 6732 (748%)

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 information (measured in megabytes per second) that can be transferred past the external memory interface in one second. It is worked out by multiplying the interface width by the speed of its memory. In the case of DDR memory, the result should be multiplied by 2 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 AA, High Dynamic Range and high resolutions.

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

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