GeForce RTX 3070 Ti vs Radeon RX 6800 XT

Intro

The GeForce RTX 3070 Ti has a GPU core clock speed of 1575 MHz, and the 8192 MB of GDDR6X memory is set to run at 1188 MHz through a 256-bit bus. It also features 6144 Stream Processors, 192 Texture Address Units, and 96 Raster Operation Units.

Compare those specs to the Radeon RX 6800 XT, which has core speeds of 1825 MHz on the GPU, and 2000 MHz on the 16384 MB of GDDR6 memory. It features 4608 SPUs along with 288 TAUs and 128 Rasterization Operator Units.

Memory Bandwidth: Bandwidth is the largest amount of data (measured in MB per second) that can be transported across the external memory interface in one second. The number is worked out by multiplying the interface width by the speed of its memory. In the case of DDR type memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster 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 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 the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly write to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
