GeForce RTX 4070 Ti vs Radeon RX 6800

Intro

The GeForce RTX 4070 Ti makes use of a 4 nm design. nVidia has clocked the core speed at 2310 MHz. The GDDR6X memory is set to run at a speed of 1313 MHz on this specific model. It features 7680 SPUs along with 240 TAUs and 80 Rasterization Operator Units.

Compare those specifications to the Radeon RX 6800, which features core speeds of 1700 MHz on the GPU, and 2000 MHz on the 16384 MB of GDDR6 memory. It features 3840 SPUs as well as 240 Texture Address Units and 96 Rasterization Operator Units.

Radeon RX 6800 250 Watts
GeForce RTX 4070 Ti 285 Watts
Difference: 35 Watts (14%)

Memory Bandwidth

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

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

Texel Rate

The GeForce RTX 4070 Ti is quite a bit (more or less 36%) better at anisotropic filtering than the Radeon RX 6800. (explain)

GeForce RTX 4070 Ti 554400 Mtexels/sec
Radeon RX 6800 408000 Mtexels/sec
Difference: 146400 (36%)

Pixel Rate

The GeForce RTX 4070 Ti is a bit (more or less 13%) faster with regards to full screen anti-aliasing than the Radeon RX 6800, and should be capable of handling higher resolutions more effectively. (explain)

GeForce RTX 4070 Ti 184800 Mpixels/sec
Radeon RX 6800 163200 Mpixels/sec
Difference: 21600 (13%)

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.

Memory Bandwidth: Memory bandwidth is the max amount of data (in units of MB per second) that can be moved over the external memory interface in one second. It's calculated by multiplying the card's bus width by its memory speed. If it uses DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, 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 amount of texture map elements (texels) that are processed in one second. This is worked out by multiplying the total number of texture units by the core clock speed of the chip. The better the texel rate, the better the video 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 could possibly record to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
