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 clocked the core speed at 1156 MHz. The HBM2 memory is set to run at a speed of 1600 MHz on this model. It features 3584 SPUs along with 224 Texture Address Units and 64 Rasterization Operator Units.

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% faster than the Radeon RX Vega 56 overall, because of its greater bandwidth. (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 is much (about 114%) better at AF 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 running with high levels of AA is important to you, then the GeForce RTX 4070 Ti is superior to the Radeon RX Vega 56, by a large margin. (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: Bandwidth is the max amount of information (measured in MB per second) that can be transferred past the external memory interface within a second. The number is worked out by multiplying the bus width by the speed of its memory. In the case of DDR memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly write to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
