GeForce GTX 590 vs Radeon RX 6650 XT

Intro

Compare all that to the Radeon RX 6650 XT, which makes use of a 7 nm design. AMD has clocked the core frequency at 2055 MHz. The GDDR6 memory works at a speed of 2190 MHz on this specific card. It features 2048 SPUs along with 128 Texture Address Units and 64 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

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

Memory Bandwidth

Theoretically, the GeForce GTX 590 should perform just 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 should be quite a bit (approximately 239%) more effective at texture 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 will be much (approximately 126%) better at anti-aliasing than the GeForce GTX 590, and also will be able to handle higher screen resolutions better. (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: Bandwidth is the max amount of data (counted in megabytes per second) that can be moved past the external memory interface in a second. It's worked out by multiplying the bus width by its memory clock speed. If the card has DDR type memory, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied per second. This figure is calculated by multiplying the total amount of texture units by the core speed of the chip. The better the texel rate, the better the graphics card will be at handling 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 record to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends 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.
