GeForce RTX 3060 vs Radeon RX Vega 64

Intro

Compare all that to the Radeon RX Vega 64, which features core speeds of 1247 MHz on the GPU, and 1890 MHz on the 8192 MB of HBM2 memory. It features 4096 SPUs as well as 256 Texture Address Units and 64 Rasterization Operator Units.

GeForce RTX 3060		368640 MB/sec
	Difference: 126771 (34%)

Texel Rate

The Radeon RX Vega 64 will be much (approximately 116%) better at AF than the GeForce RTX 3060. (explain)

Radeon RX Vega 64		319232 Mtexels/sec
GeForce RTX 3060		147840 Mtexels/sec
	Difference: 171392 (116%)

Pixel Rate

The Radeon RX Vega 64 will be quite a bit (about 26%) better at FSAA than the GeForce RTX 3060, and also able to handle higher resolutions while still performing well. (explain)

Radeon RX Vega 64		79808 Mpixels/sec
GeForce RTX 3060		63360 Mpixels/sec
	Difference: 16448 (26%)

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 maximum amount of data (in units of megabytes per second) that can be transported across the external memory interface within a second. The number is worked out by multiplying the interface width by the speed of its memory. In the case of DDR type memory, it should be multiplied by 2 once 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 higher screen 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 number of texture units by the core speed of the chip. The better the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly write to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of ROPs by the the core speed of the card. 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 many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
