Radeon R9 290 vs Radeon RX 6700 XT

Intro

The Radeon R9 290 has a GPU core speed of 800 MHz, and the 4096 MB of GDDR5 RAM is set to run at 1250 MHz through a 512-bit bus. It also is made up of 2560 SPUs, 160 Texture Address Units, and 64 ROPs.

Compare all of that to the Radeon RX 6700 XT, which has clock speeds of 2321 MHz on the GPU, and 2000 MHz on the (Unknown) MB of GDDR6 RAM. It features 2560 SPUs along with 160 TAUs and 64 ROPs.

Memory Bandwidth: Bandwidth is the maximum amount of data (measured in MB per second) that can be transported across the external memory interface within a second. The number is calculated by multiplying the interface width by its memory clock speed. If it uses DDR type RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied in one second. This is calculated by multiplying the total amount of texture units by the core clock 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 the graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
