GeForce RTX 4070 Ti vs Radeon RX Vega 56

Intro

Compare those specifications to the Radeon RX Vega 56, which comes with core clock speeds of 1156 MHz on the GPU, and 1600 MHz on the 8192 MB of HBM2 RAM. It features 3584 SPUs along with 224 TAUs and 64 ROPs.

Radeon RX Vega 56		419430 MB/sec
	Difference: 96666 (23%)

Texel Rate

The GeForce RTX 4070 Ti will be much (approximately 114%) better at texture filtering than the Radeon RX Vega 56. (explain)

GeForce RTX 4070 Ti		554400 Mtexels/sec
Radeon RX Vega 56		258944 Mtexels/sec
	Difference: 295456 (114%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce RTX 4070 Ti is superior to the Radeon RX Vega 56, and very much so. (explain)

Radeon RX Vega 56		73984 Mpixels/sec
	Difference: 110816 (150%)

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 largest amount of data (counted in MB per second) that can be moved past the external memory interface within a second. It's worked out by multiplying the card's bus width by its memory speed. If it uses DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. This number is worked out by multiplying the total number of texture units by the core clock 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 processed per second.

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly record to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. 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 reach the max fill rate.
