GeForce 8500 GT vs GeForce 930M

Intro

Compare that to the GeForce 930M, which comes with GPU core speed of 928 MHz, and 2048 MB of DDR3 RAM set to run at 900 MHz through a 64-bit bus. It also is comprised of 384 SPUs, 24 TAUs, and 8 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the GeForce 930M should perform a little bit faster than the GeForce 8500 GT in general. (explain)

GeForce 930M		14400 MB/sec
GeForce 8500 GT		12800 MB/sec
	Difference: 1600 (13%)

Texel Rate

The GeForce 930M will be quite a bit (about 519%) better at anisotropic filtering than the GeForce 8500 GT. (explain)

GeForce 930M		22272 Mtexels/sec
GeForce 8500 GT		3600 Mtexels/sec
	Difference: 18672 (519%)

Pixel Rate

The GeForce 930M is a lot (more or less 312%) better at AA than the GeForce 8500 GT, and also capable of handling higher screen resolutions without losing too much performance. (explain)

GeForce 930M		7424 Mpixels/sec
GeForce 8500 GT		1800 Mpixels/sec
	Difference: 5624 (312%)

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 maximum amount of data (counted in MB per second) that can be transferred past the external memory interface in a second. It's calculated by multiplying the card's bus width by its memory speed. In the case of DDR type memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better 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 texture map elements (texels) that are applied per second. This is calculated by multiplying the total texture units by the core speed of the chip. The higher this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

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