Geforce GTX 670 vs Radeon RX 6800

Intro

Compare all of that to the Radeon RX 6800, which features core speeds of 1700 MHz on the GPU, and 2000 MHz on the 16384 MB of GDDR6 memory. It features 3840 SPUs as well as 240 Texture Address Units and 96 ROPs.

Geforce GTX 670		192000 MB/sec
	Difference: 332288 (173%)

Texel Rate

The Radeon RX 6800 is quite a bit (about 298%) faster with regards to AF than the Geforce GTX 670. (explain)

Radeon RX 6800		408000 Mtexels/sec
Geforce GTX 670		102480 Mtexels/sec
	Difference: 305520 (298%)

Pixel Rate

If using high levels of AA is important to you, then the Radeon RX 6800 is a better choice, by far. (explain)

Radeon RX 6800		163200 Mpixels/sec
Geforce GTX 670		29280 Mpixels/sec
	Difference: 133920 (457%)

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 max amount of information (counted in MB per second) that can be transported over the external memory interface in a second. The number is worked out by multiplying the card's interface width by its memory clock speed. If the card has DDR RAM, it must be multiplied by 2 once again. If it uses 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 higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
