GeForce RTX 2080 SUPER vs Radeon RX Vega 64

Intro

Compare all of that to the Radeon RX Vega 64, which features GPU clock speed of 1247 MHz, and 8192 MB of HBM2 RAM running at 1890 MHz through a 2048-bit bus. It also is comprised of 4096 Stream Processors, 256 TAUs, and 64 ROPs.

Radeon RX Vega 64		495411 MB/sec
	Difference: 12493 (3%)

Texel Rate

The Radeon RX Vega 64 is a little bit (about 1%) faster with regards to AF than the GeForce RTX 2080 SUPER. (explain)

Radeon RX Vega 64		319232 Mtexels/sec
GeForce RTX 2080 SUPER		316800 Mtexels/sec
	Difference: 2432 (1%)

Pixel Rate

The GeForce RTX 2080 SUPER is much (approximately 32%) more effective at full screen anti-aliasing than the Radeon RX Vega 64, and will be able to handle higher resolutions while still performing well. (explain)

GeForce RTX 2080 SUPER		105600 Mpixels/sec
Radeon RX Vega 64		79808 Mpixels/sec
	Difference: 25792 (32%)

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.

Specifications

Memory Bandwidth: Bandwidth is the largest amount of data (counted in MB per second) that can be transferred across the external memory interface in one second. The number is worked out by multiplying the bus width by its memory clock speed. If the card has DDR memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the 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 texture map elements (texels) that can be applied in one second. This is worked out by multiplying the total number of texture units by the core clock 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 one second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly write to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
