GeForce GTX 1660 Ti vs GeForce GTX 590

Intro

The GeForce GTX 1660 Ti uses a 12 nm design. nVidia has set the core frequency at 1500 MHz. The GDDR6 RAM runs at a frequency of 12000 MHz on this model. It features 1536 SPUs as well as 96 Texture Address Units and 48 ROPs.

Compare that to the GeForce GTX 590, which has a core clock frequency of 607 MHz and a GDDR5 memory frequency of 855 MHz. It also features a 384-bit bus, and uses a 40 nm design. It is made up of 512 SPUs, 64 TAUs, 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

Theoretically speaking, the GeForce GTX 590 should perform a bit faster than the GeForce GTX 1660 Ti in general. (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 quite a bit (approximately 85%) better at 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 using a high screen resolution is important to you, then the GeForce GTX 1660 Ti is the winner, by far. (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.

Memory Bandwidth: Bandwidth is the maximum amount of data (in units of megabytes per second) that can be transported over the external memory interface in a second. The number is worked out by multiplying the interface width by its memory speed. In the case of DDR type memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Raster Operations Pipelines by the clock speed of the card. 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 fill rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
