Radeon RX 5700 XT vs Radeon RX 6650 XT
Intro
The Radeon RX 5700 XT has a core clock frequency of 1605 MHz and a GDDR6 memory frequency of 1750 MHz. It also uses a 256-bit memory bus, and makes use of a 7 nm design. It is made up of 2560 SPUs, 160 Texture Address Units, and 64 Raster Operation Units.Compare those specs to the Radeon RX 6650 XT, which features core clock speeds of 2055 MHz on the GPU, and 2190 MHz on the 8192 MB of GDDR6 memory. It features 2048 SPUs along with 128 TAUs and 64 Rasterization Operator Units.

Memory Bandwidth: Memory bandwidth is the max amount of data (counted in megabytes per second) that can be transported past the external memory interface in a second. It is calculated by multiplying the interface width by its memory speed. In the case of DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied per second. This figure is calculated by multiplying the total amount of texture units by the core speed of the chip. The better this number, 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 maximum number of pixels that the graphics chip can possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
