GeForce RTX 4070 Ti vs Radeon RX Vega 56

Intro

Compare 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 RAM runs at a frequency of 1600 MHz on this particular card. It features 3584 SPUs along with 224 TAUs 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% quicker than the Radeon RX Vega 56 overall, 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 a lot (approximately 114%) more effective 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 running with a high resolution is important to you, then the GeForce RTX 4070 Ti is superior to the Radeon RX Vega 56, and very much so. (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 (in units of megabytes per second) that can be transferred past the external memory interface within a second. It is worked out by multiplying the interface width by its memory clock speed. If the card has DDR RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed per second. This number is calculated by multiplying the total number of texture units of the card by the core 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 applied in a second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Render Output Units by the the core 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 output rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
