GeForce GTX 970 vs Radeon RX 6700 XT

Intro

Compare that to the Radeon RX 6700 XT, which uses a 7 nm design. AMD has set the core frequency at 2321 MHz. The GDDR6 memory runs at a speed of 2000 MHz on this card. It features 2560 SPUs as well as 160 Texture Address Units and 64 Rasterization Operator Units.

GeForce GTX 970		224000 MB/sec
	Difference: 169216 (76%)

Texel Rate

The Radeon RX 6700 XT should be quite a bit (more or less 240%) better at texture filtering than the GeForce GTX 970. (explain)

Radeon RX 6700 XT		371360 Mtexels/sec
GeForce GTX 970		109200 Mtexels/sec
	Difference: 262160 (240%)

Pixel Rate

The Radeon RX 6700 XT should be much (approximately 121%) faster with regards to AA than the GeForce GTX 970, and also capable of handling higher resolutions without slowing down too much. (explain)

Radeon RX 6700 XT		148544 Mpixels/sec
GeForce GTX 970		67200 Mpixels/sec
	Difference: 81344 (121%)

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 megabytes per second) that can be moved over the external memory interface within a second. It is worked out by multiplying the card's interface width by its memory speed. If it uses DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen 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 texture units by the core speed of the chip. The better the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly write to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
