GeForce GTX 650 Ti vs Radeon RX 590

Intro

Compare all of that to the Radeon RX 590, which comes with a GPU core clock speed of 1469 MHz, and 8192 MB of GDDR5 RAM set to run at 2000 MHz through a 256-bit bus. It also features 2304 SPUs, 144 TAUs, and 32 Raster Operation Units.

GeForce GTX 650 Ti		59392 Mtexels/sec
	Difference: 152144 (256%)

Pixel Rate

If using a high resolution is important to you, then the Radeon RX 590 is the winner, by a large margin. (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 max amount of data (in units of MB per second) that can be transported across the external memory interface within a second. It 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 better 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 number of texture map elements (texels) that can be applied in one second. This number is calculated by multiplying the total texture units by the core clock speed of the chip. The higher the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly write to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
