GeForce RTX 3060 vs Radeon RX Vega 56

Intro

Compare those specifications to the Radeon RX Vega 56, which features a GPU core clock speed of 1156 MHz, and 8192 MB of HBM2 memory set to run at 1600 MHz through a 2048-bit bus. It also is comprised of 3584 SPUs, 224 Texture Address Units, and 64 Raster Operation Units.

GeForce RTX 3060		170 Watts
Radeon RX Vega 56		210 Watts
	Difference: 40 Watts (24%)

Memory Bandwidth

Performance-wise, the Radeon RX Vega 56 should in theory be a little bit better than the GeForce RTX 3060 overall. (explain)

Radeon RX Vega 56		419430 MB/sec
GeForce RTX 3060		368640 MB/sec
	Difference: 50790 (14%)

Texel Rate

The Radeon RX Vega 56 should be a lot (about 75%) more effective at anisotropic filtering than the GeForce RTX 3060. (explain)

Radeon RX Vega 56		258944 Mtexels/sec
GeForce RTX 3060		147840 Mtexels/sec
	Difference: 111104 (75%)

Pixel Rate

The Radeon RX Vega 56 is a bit (about 17%) more effective at AA than the GeForce RTX 3060, and should be capable of handling higher screen resolutions while still performing well. (explain)

Radeon RX Vega 56		73984 Mpixels/sec
GeForce RTX 3060		63360 Mpixels/sec
	Difference: 10624 (17%)

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 across the external memory interface in one second. The number is calculated by multiplying the card's interface width by the speed of its memory. If it uses DDR memory, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly record to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
