GeForce GTX 285 2GB vs GeForce GTX 950M

Intro

Compare those specifications to the GeForce GTX 950M, which features GPU core speed of 914 MHz, and 2048 MB of DDR3 RAM running at 1000 MHz through a 128-bit bus. It also is comprised of 640 SPUs, 40 TAUs, and 16 ROPs.

GeForce GTX 950M		32000 MB/sec
	Difference: 126976 (397%)

Texel Rate

The GeForce GTX 285 2GB should be quite a bit (more or less 42%) better at AF than the GeForce GTX 950M. (explain)

GeForce GTX 285 2GB		51840 Mtexels/sec
GeForce GTX 950M		36560 Mtexels/sec
	Difference: 15280 (42%)

Pixel Rate

If running with a high screen resolution is important to you, then the GeForce GTX 285 2GB is a better choice, by far. (explain)

GeForce GTX 285 2GB		20736 Mpixels/sec
GeForce GTX 950M		14624 Mpixels/sec
	Difference: 6112 (42%)

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.

Specifications

Memory Bandwidth: Bandwidth is the max amount of data (measured in megabytes per second) that can be moved across the external memory interface in one second. It's worked out by multiplying the card's bus width by its memory clock speed. If it uses DDR RAM, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied in one second. This is worked out by multiplying the total amount of texture units by the core speed of the chip. The better the texel rate, the better the video 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 most pixels that the graphics card could possibly write to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
