GeForce RTX 3090 vs Radeon RX 560

Intro

Compare all of that to the Radeon RX 560, which uses a 14 nm design. AMD has set the core frequency at 1175 MHz. The GDDR5 RAM runs at a speed of 1750 MHz on this card. It features 1024 SPUs along with 64 TAUs and 16 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 560		80 Watts
GeForce RTX 3090		350 Watts
	Difference: 270 Watts (338%)

Memory Bandwidth

The GeForce RTX 3090, in theory, should perform quite a bit faster than the Radeon RX 560 in general. (explain)

GeForce RTX 3090		958668 MB/sec
Radeon RX 560		114688 MB/sec
	Difference: 843980 (736%)

Texel Rate

The GeForce RTX 3090 should be much (approximately 508%) faster with regards to anisotropic filtering than the Radeon RX 560. (explain)

GeForce RTX 3090		457560 Mtexels/sec
Radeon RX 560		75200 Mtexels/sec
	Difference: 382360 (508%)

Pixel Rate

The GeForce RTX 3090 is much (more or less 731%) faster with regards to AA than the Radeon RX 560, and also should be able to handle higher resolutions without slowing down too much. (explain)

GeForce RTX 3090		156240 Mpixels/sec
Radeon RX 560		18800 Mpixels/sec
	Difference: 137440 (731%)

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 largest amount of data (in units of megabytes per second) that can be transported across the external memory interface in one second. It's calculated by multiplying the bus width by its memory clock speed. If it uses DDR type RAM, it must be multiplied by 2 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 amount of texture map elements (texels) that can be applied in one second. This is worked out by multiplying the total texture units by the core 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 the video card could possibly write to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
