GeForce RTX 3070 vs Radeon RX 6800 XT

Intro

The GeForce RTX 3070 has clock speeds of 1500 MHz on the GPU, and 1750 MHz on the 8192 MB of GDDR6 RAM. It features 5888 SPUs as well as 184 TAUs and 96 ROPs.

Compare those specifications to the Radeon RX 6800 XT, which makes use of a 7 nm design. AMD has set the core frequency at 1825 MHz. The GDDR6 RAM works at a speed of 2000 MHz on this particular card. It features 4608 SPUs along with 288 Texture Address Units and 128 Rasterization Operator Units.

Memory Bandwidth: Memory bandwidth is the largest amount of information (in units of MB per second) that can be transported past the external memory interface within a second. It is calculated by multiplying the interface width by the speed of its memory. If it uses DDR type RAM, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly record to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
