GeForce GTX 590 vs Radeon RX 6650 XT

Intro

Compare those specs to the Radeon RX 6650 XT, which makes use of a 7 nm design. AMD has set the core speed at 2055 MHz. The GDDR6 RAM runs at a speed of 2190 MHz on this card. It features 2048 SPUs as well as 128 TAUs and 64 ROPs.

Radeon RX 6650 XT		176 Watts
GeForce GTX 590		365 Watts
	Difference: 189 Watts (107%)

Memory Bandwidth

The GeForce GTX 590 should theoretically be a bit faster than the Radeon RX 6650 XT in general. (explain)

GeForce GTX 590		328320 MB/sec
Radeon RX 6650 XT		287072 MB/sec
	Difference: 41248 (14%)

Texel Rate

The Radeon RX 6650 XT will be much (about 239%) better at anisotropic filtering than the GeForce GTX 590. (explain)

Radeon RX 6650 XT		263040 Mtexels/sec
GeForce GTX 590		77696 Mtexels/sec
	Difference: 185344 (239%)

Pixel Rate

The Radeon RX 6650 XT should be much (more or less 126%) more effective at AA than the GeForce GTX 590, and should be able to handle higher screen resolutions without slowing down too much. (explain)

Radeon RX 6650 XT		131520 Mpixels/sec
GeForce GTX 590		58272 Mpixels/sec
	Difference: 73248 (126%)

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: Memory bandwidth is the largest amount of data (in units of megabytes per second) that can be moved across the external memory interface in one second. The number is worked out by multiplying the card's bus width by its memory speed. If the card has DDR RAM, it 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, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied per second. This is worked out by multiplying the total amount of 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 in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Raster Operations Pipelines 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 fill rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
