Geforce GTX 680 vs Radeon RX 6950 XT

Intro

Compare all that to the Radeon RX 6950 XT, which uses a 7 nm design. AMD has set the core speed at 1925 MHz. The GDDR6 memory is set to run at a frequency of 2250 MHz on this card. It features 5120 SPUs as well as 320 Texture Address Units and 128 ROPs.

Radeon RX 6950 XT		616000 Mtexels/sec
Geforce GTX 680		128768 Mtexels/sec
	Difference: 487232 (378%)

Pixel Rate

The Radeon RX 6950 XT should be a lot (more or less 665%) more effective at anti-aliasing than the Geforce GTX 680, and should be capable of handling higher screen resolutions without slowing down too much. (explain)

Radeon RX 6950 XT		246400 Mpixels/sec
Geforce GTX 680		32192 Mpixels/sec
	Difference: 214208 (665%)

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 largest amount of data (measured in megabytes per second) that can be transferred past the external memory interface in one second. It's worked out by multiplying the bus width by the speed of its memory. In the case of DDR type 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 number of texture map elements (texels) that can be applied per second. This figure is calculated by multiplying the total amount of texture units by the core speed of the chip. The higher the texel rate, the better the graphics 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 number of pixels the graphics card can possibly record to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
