GeForce RTX 2080 SUPER vs Radeon R9 Nano

Intro

Compare all of that to the Radeon R9 Nano, which features a clock frequency of 1000 MHz and a HBM memory frequency of 500 MHz. It also makes use of a 4096-bit memory bus, and makes use of a 28 nm design. It is made up of 4096 SPUs, 256 Texture Address Units, and 64 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon R9 Nano		175 Watts
GeForce RTX 2080 SUPER		250 Watts
	Difference: 75 Watts (43%)

Memory Bandwidth

Theoretically speaking, the Radeon R9 Nano should perform a little bit faster than the GeForce RTX 2080 SUPER overall. (explain)

Radeon R9 Nano		512000 MB/sec
GeForce RTX 2080 SUPER		507904 MB/sec
	Difference: 4096 (1%)

Texel Rate

The GeForce RTX 2080 SUPER should be much (approximately 24%) more effective at texture filtering than the Radeon R9 Nano. (explain)

GeForce RTX 2080 SUPER		316800 Mtexels/sec
Radeon R9 Nano		256000 Mtexels/sec
	Difference: 60800 (24%)

Pixel Rate

If using a high resolution is important to you, then the GeForce RTX 2080 SUPER is a better choice, by far. (explain)

GeForce RTX 2080 SUPER		105600 Mpixels/sec
Radeon R9 Nano		64000 Mpixels/sec
	Difference: 41600 (65%)

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 max amount of information (measured in MB per second) that can be moved past the external memory interface within a second. The number is calculated by multiplying the bus width by the speed of its memory. If it uses DDR RAM, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the card's 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 amount of texture map elements (texels) that can be processed per second. This figure is calculated by multiplying the total texture units by the core clock speed of the chip. The better the texel rate, the better the graphics card will be at 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 the video card can possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
