GeForce GTX 580 vs GeForce RTX 2060

Intro

Compare all that to the GeForce RTX 2060, which has a clock frequency of 1365 MHz and a GDDR6 memory speed of 1750 MHz. It also makes use of a 192-bit memory bus, and uses a 12 nm design. It is comprised of 1920 SPUs, 120 TAUs, and 48 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce RTX 2060		160 Watts
GeForce GTX 580		244 Watts
	Difference: 84 Watts (53%)

Memory Bandwidth

Theoretically speaking, the GeForce RTX 2060 is 79% faster than the GeForce GTX 580 overall, because of its higher data rate. (explain)

GeForce RTX 2060		344064 MB/sec
GeForce GTX 580		192384 MB/sec
	Difference: 151680 (79%)

Texel Rate

The GeForce RTX 2060 is quite a bit (more or less 232%) more effective at texture filtering than the GeForce GTX 580. (explain)

GeForce RTX 2060		163800 Mtexels/sec
GeForce GTX 580		49408 Mtexels/sec
	Difference: 114392 (232%)

Pixel Rate

If using a high resolution is important to you, then the GeForce RTX 2060 is a better choice, and very much so. (explain)

GeForce RTX 2060		65520 Mpixels/sec
GeForce GTX 580		37056 Mpixels/sec
	Difference: 28464 (77%)

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.

Specifications

Memory Bandwidth: Memory bandwidth is the maximum amount of data (in units of MB per second) that can be transferred past the external memory interface in a second. It's calculated by multiplying the card's interface width by its memory clock speed. In the case of DDR type memory, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, 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 number of texture map elements (texels) that can be processed 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 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 the video card could possibly write to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
