GeForce GTX 590 vs Radeon RX 6600 XT

Intro

Compare that to the Radeon RX 6600 XT, which uses a 7 nm design. AMD has clocked the core frequency at 1968 MHz. The GDDR6 RAM runs at a frequency of 2000 MHz on this particular model. It features 2048 SPUs as well as 128 Texture Address Units and 64 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 6600 XT		160 Watts
GeForce GTX 590		365 Watts
	Difference: 205 Watts (128%)

Memory Bandwidth

In theory, the GeForce GTX 590 should perform much faster than the Radeon RX 6600 XT in general. (explain)

GeForce GTX 590		328320 MB/sec
Radeon RX 6600 XT		262144 MB/sec
	Difference: 66176 (25%)

Texel Rate

The Radeon RX 6600 XT will be quite a bit (approximately 224%) better at anisotropic filtering than the GeForce GTX 590. (explain)

Radeon RX 6600 XT		251904 Mtexels/sec
GeForce GTX 590		77696 Mtexels/sec
	Difference: 174208 (224%)

Pixel Rate

The Radeon RX 6600 XT is a lot (approximately 116%) better at full screen anti-aliasing than the GeForce GTX 590, and also should be capable of handling higher resolutions without slowing down too much. (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 data (in units of MB per second) that can be transferred over the external memory interface in a second. It's worked out by multiplying the bus width by its memory speed. If the card has DDR type RAM, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR 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 amount of texture units by the core speed of the chip. The better this number, 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 video card can possibly write to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
