GeForce RTX 2070 Super vs Radeon R9 390X 8G

Intro

The GeForce RTX 2070 Super has a GPU core speed of 1605 MHz, and the 8192 MB of GDDR6 memory is set to run at 14000 MHz through a 256-bit bus. It also is made up of 2560 SPUs, 160 Texture Address Units, and 64 Raster Operation Units.

Compare those specifications to the Radeon R9 390X 8G, which has a GPU core clock speed of 1050 MHz, and 8192 MB of GDDR5 RAM set to run at 1500 MHz through a 512-bit bus. It also is comprised of 2816 SPUs, 176 TAUs, and 64 ROPs.

Memory Bandwidth: Memory bandwidth is the largest amount of information (in units of megabytes per second) that can be transported over the external memory interface within a second. It's worked out by multiplying the card's bus width by its memory clock speed. In the case of DDR RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied per second. This figure is worked out by multiplying the total texture units by the core clock speed of the chip. The higher the texel rate, the better the 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 maximum amount of pixels the video card could possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
