GeForce RTX 3070 Ti vs Radeon RX 580

Intro

Compare all of that to the Radeon RX 580, which makes use of a 14 nm design. AMD has clocked the core frequency at 1257 MHz. The GDDR5 memory works at a frequency of 2000 MHz on this card. It features 2304 SPUs along with 144 TAUs and 32 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 580		185 Watts
GeForce RTX 3070 Ti		290 Watts
	Difference: 105 Watts (57%)

Memory Bandwidth

The GeForce RTX 3070 Ti should in theory perform much faster than the Radeon RX 580 in general. (explain)

GeForce RTX 3070 Ti		622899 MB/sec
Radeon RX 580		262144 MB/sec
	Difference: 360755 (138%)

Texel Rate

The GeForce RTX 3070 Ti is much (approximately 67%) better at anisotropic filtering than the Radeon RX 580. (explain)

GeForce RTX 3070 Ti		302400 Mtexels/sec
Radeon RX 580		181008 Mtexels/sec
	Difference: 121392 (67%)

Pixel Rate

The GeForce RTX 3070 Ti will be quite a bit (more or less 276%) more effective at anti-aliasing than the Radeon RX 580, and also capable of handling higher screen resolutions while still performing well. (explain)

GeForce RTX 3070 Ti		151200 Mpixels/sec
Radeon RX 580		40224 Mpixels/sec
	Difference: 110976 (276%)

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 (measured in MB per second) that can be moved past the external memory interface in one second. The number is worked out by multiplying the bus width by its memory speed. If the card has DDR RAM, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly write to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
