GeForce GTX 285 2GB vs GeForce GTX 960

Intro

Compare all of that to the GeForce GTX 960, which comes with a core clock speed of 1127 MHz and a GDDR5 memory speed of 1750 MHz. It also makes use of a 128-bit memory bus, and uses a 28 nm design. It is comprised of 1024 SPUs, 64 Texture Address Units, and 32 Raster Operation Units.

	Difference: 84 Watts (70%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 285 2GB is 42% quicker than the GeForce GTX 960 in general, due to its higher bandwidth. (explain)

GeForce GTX 285 2GB		158976 MB/sec
GeForce GTX 960		112000 MB/sec
	Difference: 46976 (42%)

Texel Rate

The GeForce GTX 960 will be a lot (more or less 39%) more effective at AF than the GeForce GTX 285 2GB. (explain)

GeForce GTX 960		72128 Mtexels/sec
GeForce GTX 285 2GB		51840 Mtexels/sec
	Difference: 20288 (39%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce GTX 960 is superior to the GeForce GTX 285 2GB, by a large margin. (explain)

GeForce GTX 960		36064 Mpixels/sec
GeForce GTX 285 2GB		20736 Mpixels/sec
	Difference: 15328 (74%)

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: Memory bandwidth is the max amount of information (counted in megabytes per second) that can be transferred past the external memory interface within a second. It's worked out by multiplying the bus width by its memory clock speed. If the card has DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the card's 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 in one second. This is worked out by multiplying the total texture units of the card by the core speed of the chip. The better this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly write to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of colour ROPs 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 rate also depends on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
