GeForce 920M vs GeForce 9500 GT 1GB GDDR3

Intro

Compare those specifications to the GeForce 9500 GT 1GB GDDR3, which features GPU core speed of 550 MHz, and 1024 MB of GDDR3 memory set to run at 800 MHz through a 128-bit bus. It also is made up of 32 Stream Processors, 16 TAUs, and 8 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the GeForce 9500 GT 1GB GDDR3 will be 78% faster than the GeForce 920M overall, due to its greater bandwidth. (explain)

GeForce 9500 GT 1GB GDDR3		25600 MB/sec
GeForce 920M		14400 MB/sec
	Difference: 11200 (78%)

Texel Rate

The GeForce 920M is a lot (approximately 247%) faster with regards to anisotropic filtering than the GeForce 9500 GT 1GB GDDR3. (explain)

GeForce 920M		30528 Mtexels/sec
GeForce 9500 GT 1GB GDDR3		8800 Mtexels/sec
	Difference: 21728 (247%)

Pixel Rate

If running with a high resolution is important to you, then the GeForce 920M is superior to the GeForce 9500 GT 1GB GDDR3, by far. (explain)

GeForce 920M		7632 Mpixels/sec
GeForce 9500 GT 1GB GDDR3		4400 Mpixels/sec
	Difference: 3232 (73%)

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 information (counted in MB per second) that can be transferred past the external memory interface within a second. It's calculated by multiplying the interface width by the speed of its memory. In the case of DDR RAM, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly write to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of ROPs by the the card's clock speed. 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 output rate also depends on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
