GeForce RTX 2070 Super vs Radeon R9 Nano

Intro

Compare those specifications to the Radeon R9 Nano, which comes with a core clock speed of 1000 MHz and a HBM memory frequency of 500 MHz. It also uses a 4096-bit bus, and uses a 28 nm design. It is comprised of 4096 SPUs, 256 TAUs, and 64 ROPs.

GeForce RTX 2070 Super		458752 MB/sec
	Difference: 53248 (12%)

Texel Rate

The GeForce RTX 2070 Super should be just a bit (more or less 0%) faster with regards to texture filtering than the Radeon R9 Nano. (explain)

GeForce RTX 2070 Super		256800 Mtexels/sec
Radeon R9 Nano		256000 Mtexels/sec
	Difference: 800 (0%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce RTX 2070 Super is superior to the Radeon R9 Nano, by far. (explain)

GeForce RTX 2070 Super		102720 Mpixels/sec
Radeon R9 Nano		64000 Mpixels/sec
	Difference: 38720 (61%)

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 largest amount of information (measured in megabytes per second) that can be transferred over the external memory interface in a second. It is worked out by multiplying the bus width by its memory clock speed. If it uses DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the 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 amount of texture map elements (texels) that can be processed in one 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 this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly record to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
