GeForce 825M vs GeForce 8600 GT 512MB DDR2

Intro

The GeForce 825M makes use of a 28 nm design. nVidia has set the core speed at 850 MHz. The DDR3 RAM runs at a speed of 900 MHz on this model. It features 384 SPUs along with 16 TAUs and 8 Rasterization Operator Units.

Compare those specifications to the GeForce 8600 GT 512MB DDR2, which features a core clock frequency of 540 MHz and a DDR2 memory frequency of 400 MHz. It also uses a 128-bit bus, and uses a 80 nm design. It is made up of 32 SPUs, 16 Texture Address Units, and 8 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 825M 33 Watts
GeForce 8600 GT 512MB DDR2 47 Watts
Difference: 14 Watts (42%)

Memory Bandwidth

As far as performance goes, the GeForce 825M should in theory be a little bit better than the GeForce 8600 GT 512MB DDR2 in general. (explain)

GeForce 825M 14400 MB/sec
GeForce 8600 GT 512MB DDR2 12800 MB/sec
Difference: 1600 (13%)

Texel Rate

The GeForce 825M is quite a bit (about 57%) more effective at anisotropic filtering than the GeForce 8600 GT 512MB DDR2. (explain)

GeForce 825M 13600 Mtexels/sec
GeForce 8600 GT 512MB DDR2 8640 Mtexels/sec
Difference: 4960 (57%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce 825M is the winner, by far. (explain)

GeForce 825M 6800 Mpixels/sec
GeForce 8600 GT 512MB DDR2 4320 Mpixels/sec
Difference: 2480 (57%)

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: Bandwidth is the maximum amount of information (in units of megabytes per second) that can be transferred past the external memory interface in a second. The number is calculated by multiplying the card's bus width by its memory speed. If the card has DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel 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 potential to reach the max fill rate.
