GeForce 8600 GTS vs GeForce GTX 950M

Intro

The GeForce 8600 GTS features clock speeds of 675 MHz on the GPU, and 1000 MHz on the 512 MB of GDDR3 memory. It features 32 SPUs along with 16 Texture Address Units and 8 ROPs.

Compare those specifications to the GeForce GTX 950M, which comes with a core clock speed of 914 MHz and a DDR3 memory frequency of 1000 MHz. It also features a 128-bit bus, and uses a 28 nm design. It is comprised of 640 SPUs, 40 TAUs, and 16 ROPs.

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 memory bandwidth, so theoretically they should have the same performance. (explain)

Texel Rate

The GeForce GTX 950M will be much (about 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

The GeForce GTX 950M is a lot (more or less 171%) better at AA than the GeForce 8600 GTS, and also will be capable of handling higher screen resolutions better. (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 largest amount of data (counted in MB per second) that can be transferred across the external memory interface in one second. It is worked out by multiplying the card's interface width by its memory speed. In the case of DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better 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 applied per second. This is calculated by multiplying the total texture units by the core speed of the chip. The higher this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly record to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
