GeForce RTX 2070 vs Radeon RX 5700 XT

Intro

The GeForce RTX 2070 makes use of a 12 nm design. nVidia has clocked the core frequency at 1410 MHz. The GDDR6 memory runs at a frequency of 1750 MHz on this specific card. It features 2304 SPUs along with 144 Texture Address Units and 64 Rasterization Operator Units.

Compare that to the Radeon RX 5700 XT, which features a GPU core clock speed of 1605 MHz, and 8096 MB of GDDR6 RAM running at 1750 MHz through a 256-bit bus. It also features 2560 Stream Processors, 160 Texture Address Units, and 64 ROPs.

Specifications

Memory Bandwidth: Bandwidth is the maximum amount of information (in units of megabytes per second) that can be moved over the external memory interface in a second. It's worked out by multiplying the interface width by the speed of its memory. In the case of DDR type memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the 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 amount of texture map elements (texels) that are applied in one second. This number is worked out by multiplying the total number of texture units by the core speed of the chip. The better this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly write to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
