GeForce GTX 1070 vs Radeon RX 5500

Intro

Compare all that to the Radeon RX 5500, which comes with a core clock speed of 1670 MHz and a GDDR6 memory frequency of 1750 MHz. It also uses a 128-bit memory bus, and uses a 7 nm design. It is made up of 1408 SPUs, 88 Texture Address Units, and 32 ROPs.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

In theory, the GeForce GTX 1070 should be a bit faster than the Radeon RX 5500 overall. (explain)

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

Texel Rate

The GeForce GTX 1070 will be quite a bit (about 23%) faster with regards to texture 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 is quite a bit (approximately 80%) faster with regards to anti-aliasing than the Radeon RX 5500, and able to handle higher resolutions without losing too much performance. (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 MB per second) that can be transferred over the external memory interface within a second. It is worked out by multiplying the card's interface width by the speed of its memory. In the case of DDR RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied per second. This figure is calculated by multiplying the total texture units by the core speed of the chip. The higher this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly record to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
