Radeon R9 290X vs Radeon RX 6700 XT

Intro

The Radeon R9 290X 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 features 2816 Stream Processors, 176 TAUs, and 64 Raster Operation Units.

Compare all that to the Radeon RX 6700 XT, which features GPU clock speed of 2321 MHz, and (Unknown) MB of GDDR6 memory set to run at 2000 MHz through a 192-bit bus. It also is comprised of 2560 Stream Processors, 160 Texture Address Units, and 64 Raster Operation Units.

Memory Bandwidth: Bandwidth is the maximum amount of information (in units of MB per second) that can be moved over the external memory interface within a second. The number is calculated by multiplying the interface width by its memory clock speed. In the case of DDR RAM, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed in one second. This number is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The better this number, the better the video 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 card could possibly write to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
