GeForce RTX 2070 vs Radeon RX 6900 XT

Intro

Compare those specifications to the Radeon RX 6900 XT, which makes use of a 7 nm design. AMD has set the core frequency at 1825 MHz. The GDDR6 RAM runs at a speed of 2000 MHz on this particular card. It features 5120 SPUs along with 320 TAUs and 128 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce RTX 2070		175 Watts
Radeon RX 6900 XT		300 Watts
	Difference: 125 Watts (71%)

Memory Bandwidth

In theory, the Radeon RX 6900 XT should perform a bit faster than the GeForce RTX 2070 in general. (explain)

Radeon RX 6900 XT		524288 MB/sec
GeForce RTX 2070		458752 MB/sec
	Difference: 65536 (14%)

Texel Rate

The Radeon RX 6900 XT will be much (more or less 188%) faster with regards to AF than the GeForce RTX 2070. (explain)

Radeon RX 6900 XT		584000 Mtexels/sec
GeForce RTX 2070		203040 Mtexels/sec
	Difference: 380960 (188%)

Pixel Rate

The Radeon RX 6900 XT is quite a bit (more or less 159%) better at FSAA than the GeForce RTX 2070, and should be able to handle higher resolutions without slowing down too much. (explain)

Radeon RX 6900 XT		233600 Mpixels/sec
GeForce RTX 2070		90240 Mpixels/sec
	Difference: 143360 (159%)

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 data (in units of megabytes per second) that can be transported past the external memory interface in one second. It's calculated by multiplying the bus width by the speed of its memory. If the card has DDR RAM, the result should be multiplied by 2 once again. If 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 higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied per second. This number is calculated by multiplying the total texture units by the core 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 per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly write to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour ROPs 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, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
