GeForce RTX 2070 Super vs Radeon R9 390 8G

Intro

The GeForce RTX 2070 Super features 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 features 2560 Stream Processors, 160 Texture Address Units, and 64 ROPs.

Compare those specs to the Radeon R9 390 8G, which has a GPU core clock speed of 1000 MHz, and 8192 MB of GDDR5 RAM running at 1500 MHz through a 512-bit bus. It also is comprised of 2560 SPUs, 160 TAUs, and 64 Raster Operation Units.

Memory Bandwidth: Memory bandwidth is the max amount of data (in units of MB per second) that can be moved past the external memory interface in a second. The number is calculated by multiplying the bus width by the speed of its memory. In the case of DDR RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. 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 number of texture map elements (texels) that can be processed in one second. This is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The higher the texel rate, the better the graphics 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 number of pixels that the graphics card can possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
