GeForce RTX 3070 vs Radeon RX 6750 XT

Intro

Compare those specs to the Radeon RX 6750 XT, which uses a 7 nm design. AMD has set the core frequency at 2150 MHz. The GDDR6 RAM works at a frequency of 2250 MHz on this specific model. It features 2560 SPUs along with 160 TAUs and 64 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce RTX 3070		220 Watts
Radeon RX 6750 XT		250 Watts
	Difference: 30 Watts (14%)

Memory Bandwidth

In theory, the Radeon RX 6750 XT should perform just a bit faster than the GeForce RTX 3070 in general. (explain)

Radeon RX 6750 XT		442368 MB/sec
GeForce RTX 3070		(Unknown) MB/sec
	Difference: 442368 (-100%)

Texel Rate

The Radeon RX 6750 XT will be much (about 25%) more effective at texture filtering than the GeForce RTX 3070. (explain)

Radeon RX 6750 XT		344000 Mtexels/sec
GeForce RTX 3070		276000 Mtexels/sec
	Difference: 68000 (25%)

Pixel Rate

The GeForce RTX 3070 is a bit (about 5%) faster with regards to anti-aliasing than the Radeon RX 6750 XT, and also should be able to handle higher resolutions without losing too much performance. (explain)

GeForce RTX 3070		144000 Mpixels/sec
Radeon RX 6750 XT		137600 Mpixels/sec
	Difference: 6400 (5%)

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 max amount of information (counted in MB per second) that can be moved past the external memory interface in a second. The number is calculated by multiplying the card's interface width by the speed of its memory. In the case of DDR RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the better 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 are applied in one second. This is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The higher this number, the better the graphics 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 most pixels the video card can possibly write to the 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 the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
