GeForce RTX 2070 Super vs Radeon R9 390X 8G

Intro

The GeForce RTX 2070 Super uses a 12 nm design. nVidia has clocked the core frequency at 1605 MHz. The GDDR6 memory is set to run at a frequency of 1750 MHz on this particular model. It features 2560 SPUs along with 160 Texture Address Units and 64 Rasterization Operator Units.

Compare that to the Radeon R9 390X 8G, which features a clock speed of 1050 MHz and a GDDR5 memory speed of 1500 MHz. It also makes use of a 512-bit bus, and uses a 28 nm design. It is comprised of 2816 SPUs, 176 TAUs, and 64 Raster Operation Units.

Specifications

Memory Bandwidth: Bandwidth is the largest amount of data (counted in MB per second) that can be transported past the external memory interface within a second. The number is calculated by multiplying the card's bus width by its memory speed. If the card has DDR type RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the faster 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 applied per second. This is calculated by multiplying the total amount of texture units of the card by the core 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 processed in a second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly write to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
