GeForce 920M vs GeForce 9500 GT 512MB GDDR3

Intro

The GeForce 920M has a GPU core clock speed of 954 MHz, and the 2048 MB of DDR3 memory runs at 900 MHz through a 64-bit bus. It also is made up of 384 SPUs, 32 Texture Address Units, and 8 ROPs.

Compare all of that to the GeForce 9500 GT 512MB GDDR3, which uses a 55 nm design. nVidia has clocked the core speed at 550 MHz. The GDDR3 RAM is set to run at a frequency of 800 MHz on this particular card. It features 32 SPUs along with 16 TAUs and 8 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the GeForce 9500 GT 512MB GDDR3 will be 78% quicker than the GeForce 920M in general, due to its higher bandwidth. (explain)

GeForce 9500 GT 512MB GDDR3 25600 MB/sec
GeForce 920M 14400 MB/sec
Difference: 11200 (78%)

Texel Rate

The GeForce 920M is quite a bit (approximately 247%) faster with regards to texture filtering than the GeForce 9500 GT 512MB GDDR3. (explain)

GeForce 920M 30528 Mtexels/sec
GeForce 9500 GT 512MB GDDR3 8800 Mtexels/sec
Difference: 21728 (247%)

Pixel Rate

The GeForce 920M will be a lot (more or less 73%) faster with regards to anti-aliasing than the GeForce 9500 GT 512MB GDDR3, and capable of handling higher resolutions without slowing down too much. (explain)

GeForce 920M 7632 Mpixels/sec
GeForce 9500 GT 512MB 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.

Memory Bandwidth: Bandwidth is the maximum amount of information (measured in MB per second) that can be transported across the external memory interface in a second. The number is worked out by multiplying the interface width by its memory clock speed. If the card has DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly record to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
