GeForce 8500 GT vs GeForce 930M

Intro

The GeForce 8500 GT makes use of a 80 nm design. nVidia has set the core speed at 450 MHz. The DDR2 RAM is set to run at a speed of 400 MHz on this particular model. It features 16 SPUs as well as 8 TAUs and 4 ROPs.

Compare that to the GeForce 930M, which features GPU clock speed of 928 MHz, and 2048 MB of DDR3 RAM running at 900 MHz through a 64-bit bus. It also is made up of 384 Stream Processors, 24 TAUs, and 8 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically, the GeForce 930M should be a little 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 (about 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 a lot (about 312%) more effective at anti-aliasing than the GeForce 8500 GT, and will be able to handle higher 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.

Memory Bandwidth: Memory bandwidth is the maximum amount of information (in units of megabytes per second) that can be transported across the external memory interface within a second. The number is calculated by multiplying the card's interface width by its memory speed. In the case of DDR type RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed in one second. This number is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
