Geforce GTX 690 vs Radeon RX 5700 XT

Intro

Compare those specifications to the Radeon RX 5700 XT, which comes with a clock speed of 1605 MHz and a GDDR6 memory frequency of 1750 MHz. It also uses a 256-bit memory bus, and uses a 7 nm design. It is comprised of 2560 SPUs, 160 Texture Address Units, and 64 ROPs.

Pixel Rate

The Radeon RX 5700 XT will be a lot (about 75%) more effective at anti-aliasing than the Geforce GTX 690, and also capable of handling higher screen resolutions while still performing well. (explain)

Radeon RX 5700 XT		102720 Mpixels/sec
Geforce GTX 690		58560 Mpixels/sec
	Difference: 44160 (75%)

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.

Price Comparison

Specifications

Memory Bandwidth: Memory bandwidth is the maximum amount of data (in units of MB per second) that can be transferred across the external memory interface in one second. The number is calculated by multiplying the card's bus width by its memory speed. In the case of DDR type memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied in one second. This number is calculated by multiplying the total 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 processed in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly record to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
