GeForce 8500 GT vs GeForce 920M

Intro

Compare all that to the GeForce 920M, which has a clock frequency of 954 MHz and a DDR3 memory frequency of 900 MHz. It also uses a 64-bit bus, and makes use of a 28 nm design. It is made up of 384 SPUs, 32 Texture Address Units, and 8 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

As far as performance goes, the GeForce 920M should in theory be a small bit superior to the GeForce 8500 GT overall. (explain)

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

Texel Rate

The GeForce 920M will be quite a bit (about 748%) better at anisotropic filtering than the GeForce 8500 GT. (explain)

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

Pixel Rate

The GeForce 920M will be a lot (more or less 324%) faster with regards to full screen anti-aliasing than the GeForce 8500 GT, and also able to handle higher screen resolutions better. (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.

Specifications

Memory Bandwidth: Memory bandwidth is the largest amount of data (in units of MB per second) that can be moved over the external memory interface in a second. The number is calculated by multiplying the card's bus width by the speed of its memory. If it uses DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, 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 figure is calculated 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 in one second.

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