Compare any two graphics cards:

GeForce GTX 590 vs GeForce RTX 2060

Intro

The GeForce GTX 590 has core speeds of 607 MHz on the GPU, and 855 MHz on the 1536 MB of GDDR5 RAM. It features 512 SPUs as well as 64 TAUs and 48 ROPs.

Compare those specs to the GeForce RTX 2060, which comes with a core clock frequency of 1365 MHz and a GDDR6 memory speed of 14000 MHz. It also uses a 192-bit bus, and uses a 12 nm design. It features 1920 SPUs, 120 Texture Address Units, and 48 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce RTX 2060		160 Watts
GeForce GTX 590		365 Watts
	Difference: 205 Watts (128%)

Memory Bandwidth

Theoretically speaking, the GeForce RTX 2060 should perform a little bit faster than the GeForce GTX 590 in general. (explain)

GeForce RTX 2060		344064 MB/sec
GeForce GTX 590		328320 MB/sec
	Difference: 15744 (5%)

Texel Rate

The GeForce RTX 2060 will be much (more or less 111%) faster with regards to anisotropic filtering than the GeForce GTX 590. (explain)

GeForce RTX 2060		163800 Mtexels/sec
GeForce GTX 590		77696 Mtexels/sec
	Difference: 86104 (111%)

Pixel Rate

The GeForce RTX 2060 will be a small bit (about 12%) more effective at FSAA than the GeForce GTX 590, and will be able to handle higher resolutions while still performing well. (explain)

GeForce RTX 2060		65520 Mpixels/sec
GeForce GTX 590		58272 Mpixels/sec
	Difference: 7248 (12%)

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: Memory bandwidth is the max amount of information (counted in MB per second) that can be moved across the external memory interface in one second. It is calculated by multiplying the bus width by its memory speed. If it uses DDR type RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better 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 are applied per second. This number is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The better 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 most pixels that the graphics chip could possibly write to its local memory in a 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 - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
