GeForce 8500 GT vs GeForce 930M

Intro

The GeForce 8500 GT features a GPU clock speed of 450 MHz, and the 512 MB of DDR2 memory is set to run at 400 MHz through a 128-bit bus. It also is made up of 16 SPUs, 8 TAUs, and 4 Raster Operation Units.

Compare those specs to the GeForce 930M, which has a clock speed of 928 MHz and a DDR3 memory frequency of 900 MHz. It also makes use of a 64-bit memory bus, and uses a 28 nm design. It features 384 SPUs, 24 TAUs, and 8 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the GeForce 930M should be 13% quicker than the GeForce 8500 GT overall, because of its greater data rate. (explain)

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

Texel Rate

The GeForce 930M is much (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

The GeForce 930M will be quite a bit (about 312%) faster with regards to FSAA than the GeForce 8500 GT, and also capable of handling higher resolutions more effectively. (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 MB per second) that can be transported over the external memory interface in one second. The number is calculated by multiplying the bus width by the speed of its memory. In the case of DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed in one second. This figure is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better the texel rate, the better the graphics 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 amount of pixels that the graphics chip can possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount 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 output rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
