GeForce GTX 460 1GB vs GeForce GTX 960

Intro

Compare all of that to the GeForce GTX 960, which comes with GPU core speed of 1127 MHz, and 2048 MB of GDDR5 memory running at 1750 MHz through a 128-bit bus. It also is made up of 1024 SPUs, 64 TAUs, and 32 ROPs.

GeForce GTX 960		120 Watts
GeForce GTX 460 1GB		160 Watts
	Difference: 40 Watts (33%)

Memory Bandwidth

The GeForce GTX 460 1GB should theoretically perform a bit faster than the GeForce GTX 960 in general. (explain)

GeForce GTX 460 1GB		115200 MB/sec
GeForce GTX 960		112000 MB/sec
	Difference: 3200 (3%)

Texel Rate

The GeForce GTX 960 is a lot (approximately 91%) better at AF than the GeForce GTX 460 1GB. (explain)

GeForce GTX 960		72128 Mtexels/sec
GeForce GTX 460 1GB		37800 Mtexels/sec
	Difference: 34328 (91%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GTX 960 is the winner, and very much so. (explain)

GeForce GTX 960		36064 Mpixels/sec
GeForce GTX 460 1GB		21600 Mpixels/sec
	Difference: 14464 (67%)

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 maximum amount of data (measured in megabytes per second) that can be transferred past the external memory interface in a second. It is worked out by multiplying the interface 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 higher the memory bandwidth, the faster 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 processed per second. This is worked out by multiplying the total texture units by the core speed of the chip. The better the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the most pixels the video card can possibly record to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of colour ROPs 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 many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
