GeForce GTX 650 Ti vs Radeon RX 590

Intro

Compare all that to the Radeon RX 590, which comes with a clock frequency of 1469 MHz and a GDDR5 memory speed of 2000 MHz. It also features a 256-bit memory bus, and makes use of a 12 nm design. It features 2304 SPUs, 144 TAUs, and 32 ROPs.

GeForce GTX 650 Ti		86400 MB/sec
	Difference: 175744 (203%)

Texel Rate

The Radeon RX 590 will be quite a bit (about 256%) faster with regards to anisotropic filtering than the GeForce GTX 650 Ti. (explain)

Radeon RX 590		211536 Mtexels/sec
GeForce GTX 650 Ti		59392 Mtexels/sec
	Difference: 152144 (256%)

Pixel Rate

If using a high screen resolution is important to you, then the Radeon RX 590 is the winner, by far. (explain)

Radeon RX 590		47008 Mpixels/sec
GeForce GTX 650 Ti		14848 Mpixels/sec
	Difference: 32160 (217%)

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: Bandwidth is the maximum amount of data (counted in MB per second) that can be moved past the external memory interface within a second. The number is calculated by multiplying the interface width by its memory speed. If it uses DDR type memory, it should be multiplied by 2 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, HDR 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 number of texture units by the core clock speed of the chip. The higher this number, the better the video 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 maximum number of pixels the video card could possibly record to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
