GeForce GTX 590 vs Radeon RX 590

Intro

Compare all of that to the Radeon RX 590, which features clock speeds of 1469 MHz on the GPU, and 2000 MHz on the 8192 MB of GDDR5 RAM. It features 2304 SPUs along with 144 TAUs and 32 ROPs.

Radeon RX 590		262144 MB/sec
	Difference: 66176 (25%)

Texel Rate

The Radeon RX 590 will be quite a bit (about 172%) faster with regards to texture filtering than the GeForce GTX 590. (explain)

Radeon RX 590		211536 Mtexels/sec
GeForce GTX 590		77696 Mtexels/sec
	Difference: 133840 (172%)

Pixel Rate

The GeForce GTX 590 should be a lot (approximately 24%) more effective at anti-aliasing than the Radeon RX 590, and also should be able to handle higher resolutions while still performing well. (explain)

GeForce GTX 590		58272 Mpixels/sec
Radeon RX 590		47008 Mpixels/sec
	Difference: 11264 (24%)

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.

One or more cards in this comparison are multi-core. This means that their bandwidth, texel and pixel rates are theoretically doubled - this does not mean the card will actually perform twice as fast, but only that it should in theory be able to. Actual game benchmarks will give a more accurate idea of what it's capable of.

Specifications

Memory Bandwidth: Memory bandwidth is the max amount of data (counted in MB per second) that can be moved over the external memory interface in one second. It's calculated by multiplying the card's bus width by its memory speed. In the case of DDR type RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed in one second. This figure is worked out by multiplying the total amount of texture units of the card 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 in a second.

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Render Output Units by the clock speed of the card. 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 many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
