Geforce GTX 670 vs Radeon RX 6700 XT

Intro

Compare all of that to the Radeon RX 6700 XT, which has a clock speed of 2321 MHz and a GDDR6 memory frequency of 2000 MHz. It also makes use of a 192-bit bus, and uses a 7 nm design. It is comprised of 2560 SPUs, 160 TAUs, and 64 ROPs.

Geforce GTX 670		102480 Mtexels/sec
	Difference: 268880 (262%)

Pixel Rate

If using a high screen resolution is important to you, then the Radeon RX 6700 XT is superior to the Geforce GTX 670, by far. (explain)

Radeon RX 6700 XT		148544 Mpixels/sec
Geforce GTX 670		29280 Mpixels/sec
	Difference: 119264 (407%)

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: Memory bandwidth is the max amount of information (in units of MB per second) that can be moved over the external memory interface in one second. The number is worked out by multiplying the card's interface width by the speed of its memory. If it uses DDR memory, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly record to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Render Output Units by the the core 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, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
