GeForce RTX 3080 12 GB vs Radeon VII

Intro

The GeForce RTX 3080 12 GB comes with a clock frequency of 1260 MHz and a GDDR6X memory speed of 1188 MHz. It also makes use of a 384-bit bus, and makes use of a 8 nm design. It is comprised of 8960 SPUs, 280 TAUs, and 112 ROPs.

Compare those specs to the Radeon VII, which features GPU core speed of 1400 MHz, and 16384 MB of HBM2 RAM set to run at 1000 MHz through a 4096-bit bus. It also is comprised of 3840 Stream Processors, 240 Texture Address Units, and 64 Raster Operation Units.

Memory Bandwidth: Memory bandwidth is the largest amount of information (measured in megabytes per second) that can be transferred past the external memory interface within a second. It's calculated by multiplying the card's interface width by the speed of its memory. If the card has DDR type memory, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed per second. This is calculated by multiplying the total number of texture units by the core clock speed of the chip. The higher the texel rate, the better the graphics 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 most pixels the video card can possibly record to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
