GeForce RTX 2080 vs Radeon RX Vega 64

Intro

The GeForce RTX 2080 comes with a clock speed of 1515 MHz and a GDDR6 memory frequency of 14 MHz. It also uses a 256-bit bus, and makes use of a 12 nm design. It is made up of 2944 SPUs, 184 Texture Address Units, and 64 ROPs.

Compare all of that to the Radeon RX Vega 64, which comes with GPU clock speed of 1247 MHz, and 8192 MB of HBM2 RAM set to run at 1890 MHz through a 2048-bit bus. It also features 4096 Stream Processors, 256 Texture Address Units, and 64 ROPs.

Radeon RX Vega 64 319232 Mtexels/sec
GeForce RTX 2080 278760 Mtexels/sec
Difference: 40472 (15%)

Pixel Rate

The GeForce RTX 2080 is a lot (about 21%) better at AA than the Radeon RX Vega 64, and capable of handling higher resolutions without slowing down too much. (explain)

GeForce RTX 2080 96960 Mpixels/sec
Radeon RX Vega 64 79808 Mpixels/sec
Difference: 17152 (21%)

Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.

Memory Bandwidth: Memory bandwidth is the largest amount of information (measured in megabytes per second) that can be transported past the external memory interface in one second. It's worked out by multiplying the bus width by its memory clock speed. If the card has DDR type memory, it must be multiplied by 2 once 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 number 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 in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly write to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
