GeForce GTX 1070 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 speed of 1750 MHz. It also uses a 256-bit memory bus, and uses a 7 nm design. It is comprised of 2560 SPUs, 160 TAUs, and 64 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 1070		150 Watts
Radeon RX 5700 XT		225 Watts
	Difference: 75 Watts (50%)

Memory Bandwidth

The Radeon RX 5700 XT, in theory, should be a lot faster than the GeForce GTX 1070 in general. (explain)

Radeon RX 5700 XT		458752 MB/sec
GeForce GTX 1070		262144 MB/sec
	Difference: 196608 (75%)

Texel Rate

The Radeon RX 5700 XT should be much (about 42%) more effective at AF than the GeForce GTX 1070. (explain)

Radeon RX 5700 XT		256800 Mtexels/sec
GeForce GTX 1070		180720 Mtexels/sec
	Difference: 76080 (42%)

Pixel Rate

If using high levels of AA is important to you, then the Radeon RX 5700 XT is a better choice, but it probably won't make a huge difference. (explain)

Radeon RX 5700 XT		102720 Mpixels/sec
GeForce GTX 1070		96384 Mpixels/sec
	Difference: 6336 (7%)

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 maximum amount of data (in units of MB per second) that can be transferred past the external memory interface in a second. The number is worked out by multiplying the card's interface width by its memory clock speed. If it uses DDR type memory, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed per second. This figure is calculated 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 video 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 most pixels that the graphics chip could possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of colour ROPs 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 rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
