GeForce 920M vs GeForce 9500 GT DDR2

Intro

Compare those specs to the GeForce 9500 GT DDR2, which uses a 65 nm design. nVidia has clocked the core speed at 550 MHz. The DDR2 memory works at a frequency of 500 MHz on this specific card. It features 32 SPUs as well as 16 TAUs and 8 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the GeForce 9500 GT DDR2 is 11% quicker than the GeForce 920M overall, because of its higher bandwidth. (explain)

GeForce 9500 GT DDR2		16000 MB/sec
GeForce 920M		14400 MB/sec
	Difference: 1600 (11%)

Texel Rate

The GeForce 920M should be a lot (about 247%) more effective at anisotropic filtering than the GeForce 9500 GT DDR2. (explain)

GeForce 920M		30528 Mtexels/sec
GeForce 9500 GT DDR2		8800 Mtexels/sec
	Difference: 21728 (247%)

Pixel Rate

The GeForce 920M will be quite a bit (about 73%) better at AA than the GeForce 9500 GT DDR2, and also should be able to handle higher resolutions without slowing down too much. (explain)

GeForce 920M		7632 Mpixels/sec
GeForce 9500 GT DDR2		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 max amount of data (measured in MB per second) that can be transferred over the external memory interface within a second. The number is worked out by multiplying the interface width by the speed of its memory. If the card has DDR memory, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. 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 number of texture map elements (texels) that are processed per second. This number 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 card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

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