GeForce RTX 2080 Ti vs Radeon RX Vega 64

Intro

The GeForce RTX 2080 Ti has a clock frequency of 1350 MHz and a GDDR6 memory frequency of 14 MHz. It also makes use of a 352-bit bus, and uses a 12 nm design. It is made up of 4352 SPUs, 272 TAUs, and 88 ROPs.

Compare that to the Radeon RX Vega 64, which has GPU core speed of 1247 MHz, and 8192 MB of HBM2 memory set to run at 1890 MHz through a 2048-bit bus. It also features 4096 SPUs, 256 Texture Address Units, and 64 ROPs.

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

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed in one second. This number is worked out by multiplying the total number of texture units by the core clock speed of the chip. The higher the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly record to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
