GeForce RTX 3080 Ti vs Radeon RX 6600 XT
Intro
The GeForce RTX 3080 Ti features a clock speed 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 made up of 10240 SPUs, 320 TAUs, and 112 Raster Operation Units.Compare those specs to the Radeon RX 6600 XT, which comes with GPU clock speed of 1968 MHz, and 8192 MB of GDDR6 RAM running at 2000 MHz through a 128-bit bus. It also features 2048 Stream Processors, 128 TAUs, and 64 ROPs.

Memory Bandwidth: Memory bandwidth is the maximum amount of data (counted in MB per second) that can be moved past the external memory interface in a second. It is calculated by multiplying the card's bus width by the speed of its memory. If the card has DDR type memory, it must be multiplied by 2 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 higher screen resolutions.
Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed in one second. This figure is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The better this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.
Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly write to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
