Geforce GTX 670 vs Radeon RX 6700 XT

Intro

Compare those specifications to the Radeon RX 6700 XT, which comes with 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 TAUs and 64 Rasterization Operator Units.

Geforce GTX 670		192000 MB/sec
	Difference: 201216 (105%)

Texel Rate

The Radeon RX 6700 XT should be a lot (more or less 262%) better at texture filtering than the Geforce GTX 670. (explain)

Radeon RX 6700 XT		371360 Mtexels/sec
Geforce GTX 670		102480 Mtexels/sec
	Difference: 268880 (262%)

Pixel Rate

The Radeon RX 6700 XT will be a lot (about 407%) better at full screen anti-aliasing than the Geforce GTX 670, and also should be able to handle higher resolutions better. (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 maximum amount of information (measured in megabytes per second) that can be transported across the external memory interface in one second. The number is worked out by multiplying the card's bus width by its memory speed. In the case of DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed per second. This figure is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the video 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 could possibly write to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
