GeForce GTX 460 SE vs GeForce GTX 960

Intro

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

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 960		120 Watts
GeForce GTX 460 SE		150 Watts
	Difference: 30 Watts (25%)

Memory Bandwidth

In theory, the GeForce GTX 960 should be 3% faster than the GeForce GTX 460 SE in general, due to its greater data rate. (explain)

GeForce GTX 960		112000 MB/sec
GeForce GTX 460 SE		108800 MB/sec
	Difference: 3200 (3%)

Texel Rate

The GeForce GTX 960 should be much (approximately 131%) better at texture filtering than the GeForce GTX 460 SE. (explain)

GeForce GTX 960		72128 Mtexels/sec
GeForce GTX 460 SE		31200 Mtexels/sec
	Difference: 40928 (131%)

Pixel Rate

The GeForce GTX 960 will be quite a bit (more or less 73%) more effective at AA than the GeForce GTX 460 SE, and capable of handling higher screen resolutions more effectively. (explain)

GeForce GTX 960		36064 Mpixels/sec
GeForce GTX 460 SE		20800 Mpixels/sec
	Difference: 15264 (73%)

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 max amount of information (counted in megabytes per second) that can be moved across the external memory interface in a second. It is calculated by multiplying the interface width by the speed of its memory. If it uses DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

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