GeForce RTX 4070 Ti vs Radeon RX 6750 XT

Intro

Compare those specs to the Radeon RX 6750 XT, which features a clock speed of 2150 MHz and a GDDR6 memory speed of 2250 MHz. It also uses a 192-bit memory bus, and uses 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)

Radeon RX 6750 XT		250 Watts
GeForce RTX 4070 Ti		285 Watts
	Difference: 35 Watts (14%)

Memory Bandwidth

In theory, the GeForce RTX 4070 Ti is 17% faster than the Radeon RX 6750 XT overall, because of its greater data rate. (explain)

GeForce RTX 4070 Ti		516096 MB/sec
Radeon RX 6750 XT		442368 MB/sec
	Difference: 73728 (17%)

Texel Rate

The GeForce RTX 4070 Ti will be much (approximately 61%) more effective at anisotropic filtering than the Radeon RX 6750 XT. (explain)

GeForce RTX 4070 Ti		554400 Mtexels/sec
Radeon RX 6750 XT		344000 Mtexels/sec
	Difference: 210400 (61%)

Pixel Rate

The GeForce RTX 4070 Ti is quite a bit (more or less 34%) more effective at AA than the Radeon RX 6750 XT, and should be able to handle higher screen resolutions without slowing down too much. (explain)

GeForce RTX 4070 Ti		184800 Mpixels/sec
Radeon RX 6750 XT		137600 Mpixels/sec
	Difference: 47200 (34%)

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 (measured in MB per second) that can be transported across the external memory interface in one second. It's calculated by multiplying the interface width by the speed of its memory. In the case of DDR type RAM, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed in one second. This is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The higher the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly write to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
