GeForce RTX 2070 vs Radeon R9 Nano

Intro

The GeForce RTX 2070 features core clock speeds of 1410 MHz on the GPU, and 14 MHz on the 8192 MB of GDDR6 RAM. It features 2304 SPUs as well as 144 Texture Address Units and 64 Rasterization Operator Units.

Compare those specs to the Radeon R9 Nano, which features a clock frequency of 1000 MHz and a HBM memory speed of 500 MHz. It also features a 4096-bit memory bus, and uses a 28 nm design. It is comprised of 4096 SPUs, 256 Texture Address Units, and 64 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

Performance-wise, the Radeon R9 Nano should in theory be a small bit superior to the GeForce RTX 2070 overall. (explain)

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

Texel Rate

The Radeon R9 Nano should be a lot (about 26%) faster with regards to AF than the GeForce RTX 2070. (explain)

Radeon R9 Nano 256000 Mtexels/sec
GeForce RTX 2070 203040 Mtexels/sec
Difference: 52960 (26%)

Pixel Rate

The GeForce RTX 2070 should be a lot (more or less 41%) more effective at full screen anti-aliasing than the Radeon R9 Nano, and capable of handling higher screen resolutions better. (explain)

GeForce RTX 2070 90240 Mpixels/sec
Radeon R9 Nano 64000 Mpixels/sec
Difference: 26240 (41%)

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.

Memory Bandwidth: Bandwidth is the maximum amount of information (measured in MB per second) that can be transported past the external memory interface within a second. It is worked out by multiplying the bus width by the speed of its memory. In the case of DDR type memory, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. This is worked out by multiplying the total texture units of the card 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 applied per second.

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly record to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. 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 fill rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
