GeForce RTX 2070 Super vs Radeon R9 390 8G

Intro

The GeForce RTX 2070 Super has a core clock speed of 1605 MHz and a GDDR6 memory frequency of 14000 MHz. It also features a 256-bit bus, and makes use of a 12 nm design. It is comprised of 2560 SPUs, 160 TAUs, and 64 ROPs.

Compare all of that to the Radeon R9 390 8G, which features clock speeds of 1000 MHz on the GPU, and 1500 MHz on the 8192 MB of GDDR5 memory. It features 2560 SPUs along with 160 Texture Address Units and 64 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce RTX 2070 Super 215 Watts
Radeon R9 390 8G 275 Watts
Difference: 60 Watts (28%)

Memory Bandwidth

In theory, the GeForce RTX 2070 Super will be 19% faster than the Radeon R9 390 8G in general, because of its greater data rate. (explain)

GeForce RTX 2070 Super 458752 MB/sec
Radeon R9 390 8G 384000 MB/sec
Difference: 74752 (19%)

Texel Rate

The GeForce RTX 2070 Super should be a lot (more or less 61%) more effective at texture filtering than the Radeon R9 390 8G. (explain)

GeForce RTX 2070 Super 256800 Mtexels/sec
Radeon R9 390 8G 160000 Mtexels/sec
Difference: 96800 (61%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce RTX 2070 Super is the winner, and very much so. (explain)

GeForce RTX 2070 Super 102720 Mpixels/sec
Radeon R9 390 8G 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.

Memory Bandwidth: Bandwidth is the max amount of data (counted in megabytes per second) that can be transferred past the external memory interface in one second. It's worked out by multiplying the bus width by its memory speed. If the card has DDR RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be 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 texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the most pixels the graphics card can 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 clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
