GeForce GTX 1660 Ti vs GeForce GTX 650 Ti

Intro

Compare all of that to the GeForce GTX 650 Ti, which uses a 28 nm design. nVidia has clocked the core speed at 928 MHz. The GDDR5 memory is set to run at a frequency of 1350 MHz on this particular model. It features 768 SPUs along with 64 TAUs and 16 ROPs.

GeForce GTX 650 Ti		86400 MB/sec
	Difference: 208512 (241%)

Texel Rate

The GeForce GTX 1660 Ti is a lot (more or less 142%) faster with regards to anisotropic filtering than the GeForce GTX 650 Ti. (explain)

GeForce GTX 1660 Ti		144000 Mtexels/sec
GeForce GTX 650 Ti		59392 Mtexels/sec
	Difference: 84608 (142%)

Pixel Rate

The GeForce GTX 1660 Ti is quite a bit (about 385%) more effective at full screen anti-aliasing than the GeForce GTX 650 Ti, and also able to handle higher resolutions better. (explain)

GeForce GTX 1660 Ti		72000 Mpixels/sec
GeForce GTX 650 Ti		14848 Mpixels/sec
	Difference: 57152 (385%)

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 MB per second) that can be transported past 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, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the better 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 can be processed in one second. This figure is worked out 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 card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of colour ROPs by the the card's clock speed. 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 output rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
