GeForce GTX 465 vs GeForce GTX 950

Intro

Compare those specifications to the GeForce GTX 950, which features GPU core speed of 1024 MHz, and 2048 MB of GDDR5 RAM set to run at 1652 MHz through a 128-bit bus. It also is made up of 768 SPUs, 48 Texture Address Units, and 32 Raster Operation Units.

The GeForce GTX 950 will be much (about 84%) better at anisotropic filtering than the GeForce GTX 465. (explain)

GeForce GTX 950		49152 Mtexels/sec
GeForce GTX 465		26708 Mtexels/sec
	Difference: 22444 (84%)

Pixel Rate

If using a high resolution is important to you, then the GeForce GTX 950 is superior to the GeForce GTX 465, by far. (explain)

GeForce GTX 950		32768 Mpixels/sec
GeForce GTX 465		19424 Mpixels/sec
	Difference: 13344 (69%)

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 max amount of information (measured in megabytes per second) that can be moved past the external memory interface in one second. It's worked out by multiplying the card's bus width by its memory speed. If it uses DDR type memory, it must 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 AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed in one second. This is calculated by multiplying the total number of texture units by the core speed of the chip. The higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly record to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
