GeForce GTX 1660 Ti vs GeForce GTX 550 Ti

Intro

Compare those specs to the GeForce GTX 550 Ti, which has clock speeds of 900 MHz on the GPU, and 1026 MHz on the 1024 MB of GDDR5 memory. It features 192 SPUs as well as 32 Texture Address Units and 24 Rasterization Operator Units.

GeForce GTX 550 Ti		98496 MB/sec
	Difference: 196416 (199%)

Texel Rate

The GeForce GTX 1660 Ti should be quite a bit (more or less 400%) more effective at texture filtering than the GeForce GTX 550 Ti. (explain)

GeForce GTX 1660 Ti		144000 Mtexels/sec
GeForce GTX 550 Ti		28800 Mtexels/sec
	Difference: 115200 (400%)

Pixel Rate

The GeForce GTX 1660 Ti will be a lot (more or less 233%) more effective at anti-aliasing than the GeForce GTX 550 Ti, and also will be capable of handling higher resolutions better. (explain)

GeForce GTX 1660 Ti		72000 Mpixels/sec
GeForce GTX 550 Ti		21600 Mpixels/sec
	Difference: 50400 (233%)

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 largest amount of information (in units of megabytes per second) that can be transferred over the external memory interface within a second. The number is calculated by multiplying the card's bus width by the speed of its memory. If it uses DDR type memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied in one second. This figure is worked out by multiplying the total texture units of the card by the core speed of the chip. The higher this number, the better the graphics 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 its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes 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 memory bandwidth is, the lower the potential to get to the maximum fill rate.
