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 speed at 1605 MHz. The GDDR6 RAM runs at a frequency of 14000 MHz on this specific card. It features 2560 SPUs as well as 160 TAUs and 64 Rasterization Operator Units.

Compare that to the Radeon R9 390X 8G, which features core clock speeds of 1050 MHz on the GPU, and 1500 MHz on the 8192 MB of GDDR5 memory. It features 2816 SPUs as well as 176 Texture Address Units and 64 Rasterization Operator Units.

Memory Bandwidth: Memory bandwidth is the largest amount of information (counted in MB per second) that can be transported across the external memory interface within a second. It is calculated by multiplying the card's bus width by the speed of its memory. In the case of DDR memory, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better 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 texture map elements (texels) that can be processed in one second. This figure 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 card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of ROPs 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 also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
