	Difference: 53248 (50%)

Texel Rate

The GeForce GTX 285 2GB will be just a bit (approximately 5%) faster with regards to texture filtering than the GeForce GTX 950. (explain)

GeForce GTX 285 2GB		51840 Mtexels/sec
GeForce GTX 950		49152 Mtexels/sec
	Difference: 2688 (5%)

Pixel Rate

If running with a high screen resolution is important to you, then the GeForce GTX 950 is a better choice, by a large margin. (explain)

GeForce GTX 950		32768 Mpixels/sec
GeForce GTX 285 2GB		20736 Mpixels/sec
	Difference: 12032 (58%)

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 largest amount of information (measured in megabytes per second) that can be moved past the external memory interface within a second. It's worked out by multiplying the bus width by the speed of its memory. If the card has DDR type RAM, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied per second. This number is worked out by multiplying the total amount of texture units by the core speed of the chip. The better this number, the better the card will be at handling 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 chip 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 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 fill rate also depends on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
