GeForce RTX 4070 Ti vs Radeon RX 6800 XT

Intro

Compare that to the Radeon RX 6800 XT, which uses a 7 nm design. AMD has set the core speed at 1825 MHz. The GDDR6 memory works at a speed of 2000 MHz on this particular model. It features 4608 SPUs along with 288 Texture Address Units and 128 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce RTX 4070 Ti		285 Watts
Radeon RX 6800 XT		300 Watts
	Difference: 15 Watts (5%)

Memory Bandwidth

In theory, the Radeon RX 6800 XT will be 2% quicker than the GeForce RTX 4070 Ti overall, because of its higher data rate. (explain)

Radeon RX 6800 XT		524288 MB/sec
GeForce RTX 4070 Ti		516096 MB/sec
	Difference: 8192 (2%)

Texel Rate

The GeForce RTX 4070 Ti will be a bit (approximately 5%) more effective at anisotropic filtering than the Radeon RX 6800 XT. (explain)

GeForce RTX 4070 Ti		554400 Mtexels/sec
Radeon RX 6800 XT		525600 Mtexels/sec
	Difference: 28800 (5%)

Pixel Rate

The Radeon RX 6800 XT will be a lot (more or less 26%) faster with regards to anti-aliasing than the GeForce RTX 4070 Ti, and capable of handling higher screen resolutions while still performing well. (explain)

Radeon RX 6800 XT		233600 Mpixels/sec
GeForce RTX 4070 Ti		184800 Mpixels/sec
	Difference: 48800 (26%)

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 data (counted in megabytes per second) that can be transferred across the external memory interface within a second. It is worked out by multiplying the card's bus width by its memory speed. In the case of DDR type RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly write to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number 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 fill rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
