GeForce 8600 GTS vs GeForce GTX 950M

Intro

The GeForce 8600 GTS comes with a GPU core clock speed of 675 MHz, and the 512 MB of GDDR3 memory runs at 1000 MHz through a 128-bit bus. It also is comprised of 32 Stream Processors, 16 TAUs, and 8 ROPs.

Compare those specs to the GeForce GTX 950M, which uses a 28 nm design. nVidia has set the core speed at 914 MHz. The DDR3 RAM works at a speed of 1000 MHz on this card. It features 640 SPUs as well as 40 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 950M 55 Watts
GeForce 8600 GTS 75 Watts
Difference: 20 Watts (36%)

Memory Bandwidth

Both cards have the exact same bandwidth, so in theory they should perform exactly the same. (explain)

Texel Rate

The GeForce GTX 950M is a lot (more or less 239%) better at AF than the GeForce 8600 GTS. (explain)

GeForce GTX 950M 36560 Mtexels/sec
GeForce 8600 GTS 10800 Mtexels/sec
Difference: 25760 (239%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GTX 950M is the winner, by a large margin. (explain)

GeForce GTX 950M 14624 Mpixels/sec
GeForce 8600 GTS 5400 Mpixels/sec
Difference: 9224 (171%)

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 transferred across the external memory interface in one second. It is calculated by multiplying the interface width by its memory speed. If it uses DDR memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly write to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
