GeForce RTX 4080 vs Radeon RX 590

Intro

Compare those specifications to the Radeon RX 590, which uses a 12 nm design. AMD has set the core speed at 1469 MHz. The GDDR5 RAM is set to run at a speed of 2000 MHz on this specific model. It features 2304 SPUs as well as 144 Texture Address Units and 32 ROPs.

Radeon RX 590		175 Watts
GeForce RTX 4080		320 Watts
	Difference: 145 Watts (83%)

Memory Bandwidth

In theory, the GeForce RTX 4080 is 180% faster than the Radeon RX 590 in general, because of its higher bandwidth. (explain)

GeForce RTX 4080		734003 MB/sec
Radeon RX 590		262144 MB/sec
	Difference: 471859 (180%)

Texel Rate

The GeForce RTX 4080 is much (about 217%) better at texture filtering than the Radeon RX 590. (explain)

GeForce RTX 4080		670320 Mtexels/sec
Radeon RX 590		211536 Mtexels/sec
	Difference: 458784 (217%)

Pixel Rate

The GeForce RTX 4080 should be quite a bit (about 425%) faster with regards to FSAA than the Radeon RX 590, and able to handle higher screen resolutions while still performing well. (explain)

GeForce RTX 4080		246960 Mpixels/sec
Radeon RX 590		47008 Mpixels/sec
	Difference: 199952 (425%)

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 information (in units of megabytes per second) that can be moved across the external memory interface within a second. It's worked out by multiplying the interface width by its memory clock speed. In the case of DDR memory, the result 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 high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
