GeForce GTX 590 vs Radeon RX 6600 XT

Intro

Compare those specifications to the Radeon RX 6600 XT, which comes with core speeds of 1968 MHz on the GPU, and 2000 MHz on the 8192 MB of GDDR6 memory. It features 2048 SPUs along with 128 Texture Address Units and 64 ROPs.

GeForce GTX 590		77696 Mtexels/sec
	Difference: 174208 (224%)

Pixel Rate

The Radeon RX 6600 XT will be a lot (about 116%) better at FSAA than the GeForce GTX 590, and also should be capable of handling higher screen resolutions better. (explain)

Radeon RX 6600 XT		125952 Mpixels/sec
GeForce GTX 590		58272 Mpixels/sec
	Difference: 67680 (116%)

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.

One or more cards in this comparison are multi-core. This means that their bandwidth, texel and pixel rates are theoretically doubled - this does not mean the card will actually perform twice as fast, but only that it should in theory be able to. Actual game benchmarks will give a more accurate idea of what it's capable of.

Specifications

Memory Bandwidth: Bandwidth is the maximum amount of information (counted in MB per second) that can be moved over the external memory interface in a second. The number is calculated by multiplying the bus width by its memory clock speed. In the case of DDR RAM, the result should be multiplied by 2 once 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 anti-aliasing, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels the video card can possibly write to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
