GeForce RTX 3070 vs Radeon RX 6750 XT

Intro

Compare those specifications to the Radeon RX 6750 XT, which features a core clock frequency of 2150 MHz and a GDDR6 memory frequency of 2250 MHz. It also uses a 192-bit bus, and makes use of a 7 nm design. It is comprised of 2560 SPUs, 160 Texture Address Units, and 64 ROPs.

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

The Radeon RX 6750 XT, in theory, should be 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 should be a lot (more or less 25%) faster with regards to 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

If using high levels of AA is important to you, then the GeForce RTX 3070 is a better choice, but not by far. (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: Bandwidth is the maximum amount of information (counted in megabytes per second) that can be transported past the external memory interface within a second. It's worked out by multiplying the card's bus width by its memory clock speed. In the case of DDR memory, the result should be multiplied by 2 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, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied in one second. This number 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 video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly write to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
