GeForce GTX 750 vs Radeon RX 590

Intro

Compare that to the Radeon RX 590, which features a core clock frequency of 1469 MHz and a GDDR5 memory speed of 2000 MHz. It also uses a 256-bit memory bus, and makes use of a 12 nm design. It is comprised of 2304 SPUs, 144 Texture Address Units, and 32 Raster Operation Units.

GeForce GTX 750		80000 MB/sec
	Difference: 182144 (228%)

Texel Rate

The Radeon RX 590 is a lot (more or less 548%) more effective at anisotropic filtering than the GeForce GTX 750. (explain)

Radeon RX 590		211536 Mtexels/sec
GeForce GTX 750		32640 Mtexels/sec
	Difference: 178896 (548%)

Pixel Rate

If using a high screen 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 750		16320 Mpixels/sec
	Difference: 30688 (188%)

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 largest amount of information (counted in megabytes per second) that can be moved past the external memory interface in one second. The number is calculated by multiplying the bus width by its memory clock speed. If it uses DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, 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 texture map elements (texels) that can be applied in one second. This figure is calculated by multiplying the total number of texture units by the core speed of the chip. The better the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly write to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Render Output Units by the the card's clock speed. 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 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 ability to reach the maximum fill rate.
