GeForce GTX 1660 Ti vs GeForce GTX 550 Ti

Intro

Compare those specifications to the GeForce GTX 550 Ti, which has core speeds of 900 MHz on the GPU, and 1026 MHz on the 1024 MB of GDDR5 RAM. It features 192 SPUs along with 32 Texture Address Units and 24 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 550 Ti		116 Watts
GeForce GTX 1660 Ti		120 Watts
	Difference: 4 Watts (3%)

Memory Bandwidth

In theory, the GeForce GTX 1660 Ti should be 199% quicker than the GeForce GTX 550 Ti in general, due to its greater data rate. (explain)

GeForce GTX 1660 Ti		294912 MB/sec
GeForce GTX 550 Ti		98496 MB/sec
	Difference: 196416 (199%)

Texel Rate

The GeForce GTX 1660 Ti will be much (more or less 400%) better at anisotropic 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

If using lots of anti-aliasing is important to you, then the GeForce GTX 1660 Ti is a better choice, and very much so. (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 maximum amount of information (counted in MB per second) that can be transported over the external memory interface in a second. The number is worked out by multiplying the bus width by its memory speed. In the case of DDR RAM, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly write to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number 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 drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
