GeForce GTX 465 vs GeForce GTX 960

Intro

Compare all that to the GeForce GTX 960, which has a core clock frequency of 1127 MHz and a GDDR5 memory speed of 1750 MHz. It also makes use of 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 465		200 Watts
	Difference: 80 Watts (67%)

Memory Bandwidth

As far as performance goes, the GeForce GTX 960 should in theory be just a bit better than the GeForce GTX 465 in general. (explain)

GeForce GTX 960		112000 MB/sec
GeForce GTX 465		102592 MB/sec
	Difference: 9408 (9%)

Texel Rate

The GeForce GTX 960 is a lot (approximately 170%) more effective at anisotropic filtering than the GeForce GTX 465. (explain)

GeForce GTX 960		72128 Mtexels/sec
GeForce GTX 465		26708 Mtexels/sec
	Difference: 45420 (170%)

Pixel Rate

The GeForce GTX 960 is much (approximately 86%) more effective at FSAA than the GeForce GTX 465, and also should be capable of handling higher screen resolutions without losing too much performance. (explain)

GeForce GTX 960		36064 Mpixels/sec
GeForce GTX 465		19424 Mpixels/sec
	Difference: 16640 (86%)

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 data (counted in megabytes per second) that can be transported over the external memory interface within a second. It is worked out by multiplying the interface width by its memory clock speed. If it uses DDR RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. 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 number of texture map elements (texels) that can be processed in one second. This figure is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly write to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
