GeForce 8500 GT vs GeForce 930M

Intro

Compare those specifications to the GeForce 930M, which comes with core clock speeds of 928 MHz on the GPU, and 900 MHz on the 2048 MB of DDR3 RAM. It features 384 SPUs along with 24 Texture Address Units and 8 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the GeForce 930M should be a small bit faster than the GeForce 8500 GT overall. (explain)

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

Texel Rate

The GeForce 930M is a lot (more or less 519%) better at AF 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 will be quite a bit (approximately 312%) faster with regards to AA than the GeForce 8500 GT, and also capable of handling higher screen resolutions while still performing well. (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 (measured in MB per second) that can be transported across the external memory interface within a second. It's worked out by multiplying the interface width by its memory clock speed. In the case of DDR type memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This number is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The better the texel rate, the better the video 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 amount of pixels that 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 amount 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 fill rate also depends on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
