GeForce GTX 1660 Ti vs GeForce GTX 590

Intro

Compare that to the GeForce GTX 590, which comes with a clock speed of 607 MHz and a GDDR5 memory frequency of 855 MHz. It also features a 384-bit memory bus, and makes use of a 40 nm design. It is made up of 512 SPUs, 64 Texture Address Units, and 48 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 1660 Ti		120 Watts
GeForce GTX 590		365 Watts
	Difference: 245 Watts (204%)

Memory Bandwidth

In theory, the GeForce GTX 590 should be 11% faster than the GeForce GTX 1660 Ti overall, because of its higher bandwidth. (explain)

GeForce GTX 590		328320 MB/sec
GeForce GTX 1660 Ti		294912 MB/sec
	Difference: 33408 (11%)

Texel Rate

The GeForce GTX 1660 Ti should be much (approximately 85%) faster with regards to anisotropic filtering than the GeForce GTX 590. (explain)

GeForce GTX 1660 Ti		144000 Mtexels/sec
GeForce GTX 590		77696 Mtexels/sec
	Difference: 66304 (85%)

Pixel Rate

If running with a high screen resolution is important to you, then the GeForce GTX 1660 Ti is the winner, and very much so. (explain)

GeForce GTX 1660 Ti		72000 Mpixels/sec
GeForce GTX 590		58272 Mpixels/sec
	Difference: 13728 (24%)

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.

One or more cards in this comparison are multi-core. This means that their bandwidth, texel and pixel rates are theoretically doubled - this does not mean the card will actually perform twice as fast, but only that it should in theory be able to. Actual game benchmarks will give a more accurate idea of what it's capable of.

Specifications

Memory Bandwidth: Memory bandwidth is the largest amount of data (measured in MB per second) that can be transferred past the external memory interface within a second. It is worked out by multiplying the card's interface width by its memory clock speed. If the card has DDR RAM, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
