Geforce GTX 680 vs Radeon RX 6700 XT

Intro

Compare all of that to the Radeon RX 6700 XT, which has core clock speeds of 2321 MHz on the GPU, and 2000 MHz on the (Unknown) MB of GDDR6 RAM. It features 2560 SPUs along with 160 Texture Address Units and 64 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Geforce GTX 680		195 Watts
Radeon RX 6700 XT		230 Watts
	Difference: 35 Watts (18%)

Memory Bandwidth

In theory, the Radeon RX 6700 XT is 105% quicker than the Geforce GTX 680 in general, because of its greater data rate. (explain)

Radeon RX 6700 XT		393216 MB/sec
Geforce GTX 680		192256 MB/sec
	Difference: 200960 (105%)

Texel Rate

The Radeon RX 6700 XT should be quite a bit (more or less 188%) better at texture filtering than the Geforce GTX 680. (explain)

Radeon RX 6700 XT		371360 Mtexels/sec
Geforce GTX 680		128768 Mtexels/sec
	Difference: 242592 (188%)

Pixel Rate

If using a high resolution is important to you, then the Radeon RX 6700 XT is the winner, by a large margin. (explain)

Radeon RX 6700 XT		148544 Mpixels/sec
Geforce GTX 680		32192 Mpixels/sec
	Difference: 116352 (361%)

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 maximum amount of information (in units of MB per second) that can be transported past the external memory interface in one second. The number is worked out by multiplying the interface width by its memory clock speed. In the case of DDR memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. 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 number of texture map elements (texels) that are applied in one second. This number is calculated by multiplying the total texture units by the core clock speed of the chip. The better 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 a second.

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