GeForce GTX 285 1GB vs GeForce GTX 960

Intro

Compare all of that to the GeForce GTX 960, which has GPU clock speed of 1127 MHz, and 2048 MB of GDDR5 RAM running at 1750 MHz through a 128-bit bus. It also features 1024 Stream Processors, 64 Texture Address Units, and 32 Raster Operation Units.

GeForce GTX 960		120 Watts
GeForce GTX 285 1GB		204 Watts
	Difference: 84 Watts (70%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 285 1GB is 42% faster than the GeForce GTX 960 overall, because of its higher bandwidth. (explain)

GeForce GTX 285 1GB		158976 MB/sec
GeForce GTX 960		112000 MB/sec
	Difference: 46976 (42%)

Texel Rate

The GeForce GTX 960 is quite a bit (approximately 39%) more effective at texture filtering than the GeForce GTX 285 1GB. (explain)

GeForce GTX 960		72128 Mtexels/sec
GeForce GTX 285 1GB		51840 Mtexels/sec
	Difference: 20288 (39%)

Pixel Rate

The GeForce GTX 960 will be a lot (more or less 74%) faster with regards to full screen anti-aliasing than the GeForce GTX 285 1GB, and will be capable of handling higher screen resolutions more effectively. (explain)

GeForce GTX 960		36064 Mpixels/sec
GeForce GTX 285 1GB		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: Bandwidth is the largest amount of information (measured in MB per second) that can be moved across the external memory interface in a second. It's worked out by multiplying the card's bus width by the speed of its memory. If the card has DDR memory, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed per second. This is worked out by multiplying the total texture units of the card by the core 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 applied in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
