GeForce RTX 3070 vs Radeon RX 6950 XT

Intro

The GeForce RTX 3070 makes use of a 8 nm design. nVidia has set the core frequency at 1500 MHz. The GDDR6 memory is set to run at a frequency of 1750 MHz on this particular model. It features 5888 SPUs as well as 184 Texture Address Units and 96 Rasterization Operator Units.

Compare all of that to the Radeon RX 6950 XT, which comes with GPU core speed of 1925 MHz, and 16384 MB of GDDR6 memory running at 2250 MHz through a 256-bit bus. It also is comprised of 5120 Stream Processors, 320 Texture Address Units, and 128 Raster Operation Units.

Memory Bandwidth: Memory bandwidth is the max amount of data (measured in megabytes per second) that can be transferred across the external memory interface within a second. The number is worked out by multiplying the interface width by its memory speed. In the case of DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied in one second. This number is calculated by multiplying the total texture units by the core speed of the chip. The better the texel rate, the better the video 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 the video card could possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
