GeForce RTX 4080 vs Radeon RX 6750 XT

Intro

Compare that to the Radeon RX 6750 XT, which makes use of a 7 nm design. AMD has clocked the core speed at 2150 MHz. The GDDR6 RAM runs at a frequency of 2250 MHz on this specific card. It features 2560 SPUs as well as 160 Texture Address Units and 64 ROPs.

Radeon RX 6750 XT		250 Watts
GeForce RTX 4080		320 Watts
	Difference: 70 Watts (28%)

Memory Bandwidth

Theoretically speaking, the GeForce RTX 4080 will be 66% faster than the Radeon RX 6750 XT overall, due to its higher data rate. (explain)

GeForce RTX 4080		734003 MB/sec
Radeon RX 6750 XT		442368 MB/sec
	Difference: 291635 (66%)

Texel Rate

The GeForce RTX 4080 is much (about 95%) better at anisotropic filtering than the Radeon RX 6750 XT. (explain)

GeForce RTX 4080		670320 Mtexels/sec
Radeon RX 6750 XT		344000 Mtexels/sec
	Difference: 326320 (95%)

Pixel Rate

If using high levels of AA is important to you, then the GeForce RTX 4080 is a better choice, and very much so. (explain)

GeForce RTX 4080		246960 Mpixels/sec
Radeon RX 6750 XT		137600 Mpixels/sec
	Difference: 109360 (79%)

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 megabytes per second) that can be transferred over the external memory interface within a second. It is calculated by multiplying the card's interface width by the speed of its memory. In the case of DDR RAM, it 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 AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied per second. This is worked out by multiplying the total texture units of the card by the core speed of the chip. The better this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one 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. The number is calculated by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
