GeForce RTX 2070 Super vs Radeon R9 390 8G

Intro

The GeForce RTX 2070 Super makes use of a 12 nm design. nVidia has clocked the core frequency at 1605 MHz. The GDDR6 RAM runs at a speed of 14000 MHz on this particular card. It features 2560 SPUs as well as 160 TAUs and 64 ROPs.

Compare those specs to the Radeon R9 390 8G, which comes with a core clock frequency of 1000 MHz and a GDDR5 memory frequency of 1500 MHz. It also features a 512-bit memory bus, and uses a 28 nm design. It is comprised of 2560 SPUs, 160 Texture Address Units, and 64 Raster Operation Units.

Memory Bandwidth: Memory bandwidth is the largest amount of data (in units of megabytes per second) that can be moved over the external memory interface within a second. It is worked out by multiplying the card's bus width by the speed of its memory. In the case of DDR type memory, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied in one second. This is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The higher this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly write to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output 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 reach the maximum fill rate.
