Compare any two graphics cards:
GeForce GTX 1660 Ti vs GeForce GTX 590
IntroThe GeForce GTX 1660 Ti uses a 12 nm design. nVidia has clocked the core speed 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 all of that to the GeForce GTX 590, which uses a 40 nm design. nVidia has set the core speed at 607 MHz. The GDDR5 memory works at a speed of 855 MHz on this specific card. It features 512 SPUs as well as 64 TAUs and 48 Rasterization Operator Units.
Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
The GeForce GTX 590 should in theory be a bit faster than the GeForce GTX 1660 Ti in general. (explain)
Texel RateThe GeForce GTX 1660 Ti is quite a bit (about 85%) better at AF than the GeForce GTX 590. (explain)
Pixel RateIf running with lots of anti-aliasing is important to you, then the GeForce GTX 1660 Ti is a better choice, by far. (explain)
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.
Please note that the price comparisons are based on search keywords - sometimes it might show cards with very similar names that are not exactly the same as the one chosen in the comparison. We do try to filter out the wrong results as best we can, though.
Memory Bandwidth: Memory bandwidth is the largest amount of data (counted in MB per second) that can be transferred over the external memory interface within a second. It's calculated by multiplying the card's interface width by its memory clock speed. In the case of DDR RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the 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 texture map elements (texels) that can be processed in one second. This is worked out by multiplying the total texture units by the core speed of the chip. The better the texel rate, the better the video 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 card could possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount 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 output rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
