GeForce GTX 465 vs GeForce GTX 960

Intro

Compare those specifications to the GeForce GTX 960, which makes use of a 28 nm design. nVidia has set the core frequency at 1127 MHz. The GDDR5 memory is set to run at a frequency of 1750 MHz on this specific model. It features 1024 SPUs as well as 64 Texture Address Units and 32 ROPs.

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 a small bit better than the GeForce GTX 465 overall. (explain)

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

Texel Rate

The GeForce GTX 960 will be quite a bit (about 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

If using lots of anti-aliasing is important to you, then the GeForce GTX 960 is superior to the GeForce GTX 465, by far. (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: Memory bandwidth is the maximum amount of information (counted in megabytes per second) that can be transported over the external memory interface in one second. It's calculated by multiplying the interface width by the speed of its memory. If it uses DDR type memory, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the bandwidth is, 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 number of texture map elements (texels) that are applied per second. This number is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The better this number, the better the video 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 amount of pixels that the graphics card can possibly write to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
