GeForce RTX 3070 Ti vs Radeon RX 6900 XT

Intro

The GeForce RTX 3070 Ti comes with a clock frequency of 1575 MHz and a GDDR6X memory speed of 1188 MHz. It also features a 256-bit bus, and uses a 8 nm design. It is comprised of 6144 SPUs, 192 TAUs, and 96 ROPs.

Compare those specifications to the Radeon RX 6900 XT, which makes use of a 7 nm design. AMD has clocked the core frequency at 1825 MHz. The GDDR6 memory runs at a frequency of 2000 MHz on this specific card. It features 5120 SPUs along with 320 TAUs and 128 Rasterization Operator Units.

Memory Bandwidth: Bandwidth is the max amount of data (measured in megabytes per second) that can be transferred across the external memory interface within a second. It's worked out by multiplying the interface width by its memory clock speed. If the card has DDR type memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better 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 amount of texture map elements (texels) that can be applied in one second. This figure 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 card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
