GeForce GTX 275 vs GeForce GTX 960

Intro

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

GeForce GTX 960		120 Watts
GeForce GTX 275		219 Watts
	Difference: 99 Watts (83%)

Memory Bandwidth

In theory, the GeForce GTX 275 should be just a bit faster than the GeForce GTX 960 overall. (explain)

GeForce GTX 275		127008 MB/sec
GeForce GTX 960		112000 MB/sec
	Difference: 15008 (13%)

Texel Rate

The GeForce GTX 960 will be quite a bit (about 42%) better at AF than the GeForce GTX 275. (explain)

GeForce GTX 960		72128 Mtexels/sec
GeForce GTX 275		50640 Mtexels/sec
	Difference: 21488 (42%)

Pixel Rate

The GeForce GTX 960 should be quite a bit (approximately 103%) better at FSAA than the GeForce GTX 275, and will be capable of handling higher screen resolutions without losing too much performance. (explain)

GeForce GTX 960		36064 Mpixels/sec
GeForce GTX 275		17724 Mpixels/sec
	Difference: 18340 (103%)

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 (in units of megabytes per second) that can be transported past the external memory interface in a second. It is worked out by multiplying the interface width by its memory clock speed. If the card has DDR memory, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed per second. This number is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The higher the texel rate, the better the graphics 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 could possibly write to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
