GeForce GTX 1660 Ti vs GeForce GTX 590

Intro

Compare those specifications to the GeForce GTX 590, which has core speeds of 607 MHz on the GPU, and 855 MHz on the 1536 MB of GDDR5 memory. It features 512 SPUs as well as 64 Texture Address Units and 48 ROPs.

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

Texel Rate

The GeForce GTX 1660 Ti should be a lot (about 85%) faster with regards to AF 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 using lots of anti-aliasing is important to you, then the GeForce GTX 1660 Ti is superior to the GeForce GTX 590, by a large margin. (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 maximum amount of data (in units of megabytes per second) that can be transferred over the external memory interface in one second. The number is calculated by multiplying the card's interface width by the speed of its memory. In the case of DDR RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher 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 applied in one second. This is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The better this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly write to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of Raster Operations Pipelines by the the core 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 fill rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
