GeForce GTX 1070 vs Radeon RX 5500

Intro

Compare those specifications to the Radeon RX 5500, which has a clock frequency of 1670 MHz and a GDDR6 memory speed of 1750 MHz. It also features a 128-bit bus, and makes use of a 7 nm design. It is made up of 1408 SPUs, 88 TAUs, and 32 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

Performance-wise, the GeForce GTX 1070 should theoretically be just a bit better than the Radeon RX 5500 in general. (explain)

GeForce GTX 1070		262144 MB/sec
Radeon RX 5500		229376 MB/sec
	Difference: 32768 (14%)

Texel Rate

The GeForce GTX 1070 is much (more or less 23%) faster with regards to anisotropic filtering than the Radeon RX 5500. (explain)

GeForce GTX 1070		180720 Mtexels/sec
Radeon RX 5500		146960 Mtexels/sec
	Difference: 33760 (23%)

Pixel Rate

The GeForce GTX 1070 should be much (more or less 80%) faster with regards to full screen anti-aliasing than the Radeon RX 5500, and also will be able to handle higher resolutions more effectively. (explain)

GeForce GTX 1070		96384 Mpixels/sec
Radeon RX 5500		53440 Mpixels/sec
	Difference: 42944 (80%)

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 megabytes per second) that can be moved across the external memory interface within a second. It is worked out by multiplying the card's bus width by the speed of its memory. If it uses DDR type RAM, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, 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 applied in one second. This figure is calculated by multiplying the total texture units of the card by the core speed of the chip. The better this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly record to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
