GeForce GTX 650 Ti 2GB vs GeForce GTX 960

Intro

Compare all of that to the GeForce GTX 960, which uses a 28 nm design. nVidia has set the core speed at 1127 MHz. The GDDR5 RAM works at a frequency of 1750 MHz on this specific model. It features 1024 SPUs along with 64 Texture Address Units and 32 Rasterization Operator Units.

GeForce GTX 650 Ti 2GB		59392 Mtexels/sec
	Difference: 12736 (21%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce GTX 960 is a better choice, by a large margin. (explain)

GeForce GTX 960		36064 Mpixels/sec
GeForce GTX 650 Ti 2GB		14848 Mpixels/sec
	Difference: 21216 (143%)

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 information (counted in MB per second) that can be transported across the external memory interface in one second. The number is worked out by multiplying the card's bus width by its memory speed. In the case of DDR memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the memory bandwidth, 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 texture map elements (texels) that are applied per second. This number 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 video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Raster Operations Pipelines by the clock 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 many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
