GeForce 920M vs GeForce 9500 GT DDR2

Intro

The GeForce 920M has a clock speed of 954 MHz and a DDR3 memory frequency of 900 MHz. It also features a 64-bit bus, and makes use of a 28 nm design. It is comprised of 384 SPUs, 32 TAUs, and 8 ROPs.

Compare that to the GeForce 9500 GT DDR2, which features GPU clock speed of 550 MHz, and 256 MB of DDR2 memory running at 500 MHz through a 128-bit bus. It also is made up of 32 Stream Processors, 16 TAUs, and 8 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The GeForce 9500 GT DDR2, in theory, should be a bit faster than the GeForce 920M overall. (explain)

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

Texel Rate

The GeForce 920M is a lot (approximately 247%) more effective at texture 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

If using high levels of AA is important to you, then the GeForce 920M is a better choice, and very much so. (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.

Memory Bandwidth: Memory bandwidth is the largest amount of data (counted in MB per second) that can be moved across the external memory interface in a second. The number is worked out by multiplying the card's interface width by its memory clock speed. In the case of DDR type memory, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen 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 number of texture units by the core clock speed of the chip. The higher this number, the better the video card will be at handling 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 chip can possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
