GeForce RTX 2070 Super vs Radeon R9 Nano

Intro

Compare those specifications to the Radeon R9 Nano, which uses a 28 nm design. AMD has clocked the core frequency at 1000 MHz. The HBM memory is set to run at a frequency of 500 MHz on this particular card. It features 4096 SPUs as well as 256 Texture Address Units and 64 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon R9 Nano		175 Watts
GeForce RTX 2070 Super		215 Watts
	Difference: 40 Watts (23%)

Memory Bandwidth

In theory, the Radeon R9 Nano should be 12% quicker than the GeForce RTX 2070 Super in general, due to its higher bandwidth. (explain)

Radeon R9 Nano		512000 MB/sec
GeForce RTX 2070 Super		458752 MB/sec
	Difference: 53248 (12%)

Texel Rate

The GeForce RTX 2070 Super will be a bit (approximately 0%) better at AF 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 using 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 maximum amount of information (counted in megabytes per second) that can be moved over the external memory interface within a second. It is calculated by multiplying the card's bus width by its memory speed. If it uses DDR type RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, 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 are applied per second. This is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
