GeForce GTX 950 vs Radeon RX 5700 XT

Intro

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

GeForce GTX 950		105728 MB/sec
	Difference: 353024 (334%)

Texel Rate

The Radeon RX 5700 XT is a lot (about 422%) faster with regards to anisotropic filtering than the GeForce GTX 950. (explain)

Radeon RX 5700 XT		256800 Mtexels/sec
GeForce GTX 950		49152 Mtexels/sec
	Difference: 207648 (422%)

Pixel Rate

If using a high screen resolution is important to you, then the Radeon RX 5700 XT is the winner, and very much so. (explain)

Radeon RX 5700 XT		102720 Mpixels/sec
GeForce GTX 950		32768 Mpixels/sec
	Difference: 69952 (213%)

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 maximum amount of data (measured in MB per second) that can be transported over the external memory interface within a second. It's calculated by multiplying the card's interface width by its memory speed. If it uses DDR RAM, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the 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 amount of texture map elements (texels) that are applied per second. This number is calculated by multiplying the total texture units of the card by the core clock 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 number of pixels that the graphics card could possibly write to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
