GeForce 8500 GT vs GeForce 930M

Intro

The GeForce 8500 GT uses a 80 nm design. nVidia has clocked the core speed at 450 MHz. The DDR2 memory runs at a frequency of 400 MHz on this specific card. It features 16 SPUs as well as 8 Texture Address Units and 4 Rasterization Operator Units.

Compare all that to the GeForce 930M, which makes use of a 28 nm design. nVidia has set the core speed at 928 MHz. The DDR3 RAM is set to run at a frequency of 900 MHz on this card. It features 384 SPUs along with 24 TAUs and 8 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the GeForce 930M should perform a 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 should be a lot (approximately 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

If using a high resolution is important to you, then the GeForce 930M is the winner, and very much so. (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.

Memory Bandwidth: Memory bandwidth is the maximum amount of data (measured in megabytes per second) that can be transported over the external memory interface in a second. It is worked out by multiplying the interface width by its memory speed. In the case of DDR RAM, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, 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 amount of texture map elements (texels) that can be processed per second. This is worked out by multiplying the total number of texture units by the core speed of the chip. The higher this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

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