	Difference: 73728 (17%)

Texel Rate

The GeForce RTX 4070 Ti will be quite a bit (more or less 61%) faster with regards to 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 will be quite a bit (about 34%) better at anti-aliasing than the Radeon RX 6750 XT, and also will be able to handle higher resolutions without losing too much performance. (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: Bandwidth is the max amount of information (in units of megabytes per second) that can be transported over the external memory interface in a second. It is worked out by multiplying the interface width by its memory speed. If it uses DDR RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, 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 per second. This figure is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant 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.
