GeForce RTX 3070 vs Radeon RX 6950 XT

Intro

Compare all of that to the Radeon RX 6950 XT, which comes with a clock speed of 1925 MHz and a GDDR6 memory speed of 2250 MHz. It also features a 256-bit bus, and makes use of a 7 nm design. It is made up of 5120 SPUs, 320 Texture Address Units, and 128 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce RTX 3070		220 Watts
Radeon RX 6950 XT		335 Watts
	Difference: 115 Watts (52%)

Memory Bandwidth

Theoretically speaking, the Radeon RX 6950 XT will be -100% faster than the GeForce RTX 3070 in general, due to its greater bandwidth. (explain)

Radeon RX 6950 XT		589824 MB/sec
GeForce RTX 3070		(Unknown) MB/sec
	Difference: 589824 (-100%)

Texel Rate

The Radeon RX 6950 XT will be quite a bit (more or less 123%) faster with regards to anisotropic filtering than the GeForce RTX 3070. (explain)

Radeon RX 6950 XT		616000 Mtexels/sec
GeForce RTX 3070		276000 Mtexels/sec
	Difference: 340000 (123%)

Pixel Rate

The Radeon RX 6950 XT should be much (about 71%) better at FSAA than the GeForce RTX 3070, and also should be able to handle higher screen resolutions better. (explain)

Radeon RX 6950 XT		246400 Mpixels/sec
GeForce RTX 3070		144000 Mpixels/sec
	Difference: 102400 (71%)

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 information (in units of MB per second) that can be transferred over the external memory interface in a second. The number is calculated by multiplying the bus width by the speed of its memory. If the card has DDR RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the card's 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 are applied per second. This number is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
