Radeon RX 590 vs Radeon RX 6650 XT

Intro

Compare all that to the Radeon RX 6650 XT, which uses a 7 nm design. AMD has set the core frequency at 2055 MHz. The GDDR6 RAM is set to run at a speed of 2190 MHz on this specific card. It features 2048 SPUs as well as 128 Texture Address Units and 64 Rasterization Operator Units.

Memory Bandwidth

The Radeon RX 6650 XT should theoretically be just a bit faster than the Radeon RX 590 overall. (explain)

Radeon RX 6650 XT		287072 MB/sec
Radeon RX 590		262144 MB/sec
	Difference: 24928 (10%)

Texel Rate

The Radeon RX 6650 XT should be a lot (about 24%) faster with regards to texture filtering than the Radeon RX 590. (explain)

Radeon RX 6650 XT		263040 Mtexels/sec
Radeon RX 590		211536 Mtexels/sec
	Difference: 51504 (24%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon RX 6650 XT is the winner, and very much so. (explain)

Radeon RX 6650 XT		131520 Mpixels/sec
Radeon RX 590		47008 Mpixels/sec
	Difference: 84512 (180%)

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: Bandwidth is the largest amount of information (counted in MB per second) that can be transported past the external memory interface in one second. It's calculated by multiplying the interface width by its memory clock speed. If the card has DDR RAM, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, the faster 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 amount of texture map elements (texels) that are applied per second. This is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The better the texel rate, 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 number of pixels that the graphics chip can possibly record to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. 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 ability to get to the maximum fill rate.
