GeForce RTX 3080 vs Radeon RX 5500

Intro

Compare that to the Radeon RX 5500, which makes use of a 7 nm design. AMD has clocked the core speed at 1670 MHz. The GDDR6 RAM works at a frequency of 1750 MHz on this particular card. It features 1408 SPUs along with 88 Texture Address Units and 32 ROPs.

Radeon RX 5500		146960 Mtexels/sec
	Difference: 244720 (167%)

Pixel Rate

The GeForce RTX 3080 is quite a bit (approximately 159%) faster with regards to FSAA than the Radeon RX 5500, and will be able to handle higher resolutions while still performing well. (explain)

GeForce RTX 3080		138240 Mpixels/sec
Radeon RX 5500		53440 Mpixels/sec
	Difference: 84800 (159%)

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 (measured in megabytes per second) that can be transported past the external memory interface in a second. It is worked out by multiplying the bus width by its memory clock speed. In the case of DDR RAM, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed per second. This is calculated by multiplying the total number of texture units of the card by the core clock 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 in one second.

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out 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 is also dependant on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
