GeForce RTX 3080 Ti vs Radeon RX 570

Intro

The GeForce RTX 3080 Ti has a core clock frequency of 1365 MHz and a GDDR6X memory frequency of 1188 MHz. It also makes use of a 384-bit memory bus, and makes use of a 8 nm design. It is comprised of 10240 SPUs, 320 Texture Address Units, and 112 Raster Operation Units.

Compare those specs to the Radeon RX 570, which makes use of a 14 nm design. AMD has clocked the core speed at 1168 MHz. The GDDR5 RAM is set to run at a frequency of 1750 MHz on this model. It features 2048 SPUs along with 128 TAUs and 32 Rasterization Operator Units.

Specifications

Memory Bandwidth: Bandwidth is the max amount of data (in units of megabytes per second) that can be transported over the external memory interface in a second. The number is calculated by multiplying the interface width by its memory clock speed. In the case of DDR type RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly write to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Raster Operations Pipelines 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 rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
