GeForce RTX 4070 Ti vs Radeon RX Vega 56

Intro

Compare all that to the Radeon RX Vega 56, which makes use of a 14 nm design. AMD has set the core frequency at 1156 MHz. The HBM2 memory runs at a speed of 1600 MHz on this model. It features 3584 SPUs along with 224 TAUs and 64 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX Vega 56		210 Watts
GeForce RTX 4070 Ti		285 Watts
	Difference: 75 Watts (36%)

Memory Bandwidth

Theoretically speaking, the GeForce RTX 4070 Ti should be 23% quicker than the Radeon RX Vega 56 in general, because of its higher data rate. (explain)

GeForce RTX 4070 Ti		516096 MB/sec
Radeon RX Vega 56		419430 MB/sec
	Difference: 96666 (23%)

Texel Rate

The GeForce RTX 4070 Ti should be much (more or less 114%) faster with regards to 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

The GeForce RTX 4070 Ti should be quite a bit (approximately 150%) better at FSAA than the Radeon RX Vega 56, and capable of handling higher screen resolutions without slowing down too much. (explain)

GeForce RTX 4070 Ti		184800 Mpixels/sec
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 (in units of MB per second) that can be transferred over the external memory interface within a second. It is calculated by multiplying the card's interface width by its memory speed. If the card has DDR type memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels the video card can possibly record to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
