GeForce GTX 960 vs Radeon RX 590

Intro

Compare all of that to the Radeon RX 590, which comes with a clock speed 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 960		112000 MB/sec
	Difference: 150144 (134%)

Texel Rate

The Radeon RX 590 will be much (about 193%) better at texture filtering than the GeForce GTX 960. (explain)

Radeon RX 590		211536 Mtexels/sec
GeForce GTX 960		72128 Mtexels/sec
	Difference: 139408 (193%)

Pixel Rate

The Radeon RX 590 is quite a bit (more or less 30%) faster with regards to AA than the GeForce GTX 960, and also will be capable of handling higher screen resolutions more effectively. (explain)

Radeon RX 590		47008 Mpixels/sec
GeForce GTX 960		36064 Mpixels/sec
	Difference: 10944 (30%)

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 over the external memory interface within a second. It is worked out by multiplying the bus width by its memory clock speed. If the card has DDR type memory, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better 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 texture map elements (texels) that can be processed per second. This is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The higher this number, the better the video card will be at 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 graphics card could possibly record to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill 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 get to the maximum fill rate.
