GeForce 9500 GT 1GB GDDR3 vs GeForce GTX 950M

Intro

The GeForce 9500 GT 1GB GDDR3 features a GPU clock speed of 550 MHz, and the 1024 MB of GDDR3 RAM runs at 800 MHz through a 128-bit bus. It also is made up of 32 Stream Processors, 16 TAUs, and 8 Raster Operation Units.

Compare all that to the GeForce GTX 950M, which uses a 28 nm design. nVidia has set the core speed at 914 MHz. The DDR3 RAM is set to run at a speed of 1000 MHz on this particular model. It features 640 SPUs as well as 40 Texture Address Units and 16 ROPs.

Difference: 6400 (25%)

Texel Rate

The GeForce GTX 950M is quite a bit (more or less 315%) better at texture filtering than the GeForce 9500 GT 1GB GDDR3. (explain)

GeForce GTX 950M 36560 Mtexels/sec
GeForce 9500 GT 1GB GDDR3 8800 Mtexels/sec
Difference: 27760 (315%)

Pixel Rate

The GeForce GTX 950M will be quite a bit (more or less 232%) better at AA than the GeForce 9500 GT 1GB GDDR3, and also will be able to handle higher screen resolutions better. (explain)

GeForce GTX 950M 14624 Mpixels/sec
GeForce 9500 GT 1GB GDDR3 4400 Mpixels/sec
Difference: 10224 (232%)

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 max amount of data (in units of MB per second) that can be transferred over the external memory interface in one second. It is worked out by multiplying the card's interface width by its memory clock speed. If the card has DDR type RAM, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster 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 amount of texture map elements (texels) that are processed per second. This is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Render Output Units 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 lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
