GeForce 8500 GT vs GeForce 920M

Intro

The GeForce 8500 GT comes with a clock speed of 450 MHz and a DDR2 memory frequency of 400 MHz. It also uses a 128-bit bus, and uses a 80 nm design. It is comprised of 16 SPUs, 8 TAUs, and 4 Raster Operation Units.

Compare those specs to the GeForce 920M, which features core clock speeds of 954 MHz on the GPU, and 900 MHz on the 2048 MB of DDR3 RAM. It features 384 SPUs as well as 32 TAUs and 8 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The GeForce 920M should theoretically be a bit faster than the GeForce 8500 GT in general. (explain)

GeForce 920M 14400 MB/sec
GeForce 8500 GT 12800 MB/sec
Difference: 1600 (13%)

Texel Rate

The GeForce 920M should be quite a bit (approximately 748%) faster with regards to texture filtering than the GeForce 8500 GT. (explain)

GeForce 920M 30528 Mtexels/sec
GeForce 8500 GT 3600 Mtexels/sec
Difference: 26928 (748%)

Pixel Rate

If running with a high resolution is important to you, then the GeForce 920M is a better choice, and very much so. (explain)

GeForce 920M 7632 Mpixels/sec
GeForce 8500 GT 1800 Mpixels/sec
Difference: 5832 (324%)

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 information (measured in MB per second) that can be transferred across the external memory interface within a second. The number is calculated by multiplying the card's interface width by its memory speed. If the card has DDR memory, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the card's 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 can be processed per second. This number is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The better the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly write to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
