Radeon R9 290X vs Radeon RX 6650 XT

Intro

The Radeon R9 290X has a GPU core speed of 800 MHz, and the 4096 MB of GDDR5 memory runs at 1250 MHz through a 512-bit bus. It also is made up of 2816 SPUs, 176 TAUs, and 64 Raster Operation Units.

Compare those specifications 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 RAM works at a frequency of 2190 MHz on this specific card. It features 2048 SPUs along with 128 TAUs and 64 ROPs.

Radeon RX 6650 XT 263040 Mtexels/sec
Radeon R9 290X 140800 Mtexels/sec
Difference: 122240 (87%)

Pixel Rate

The Radeon RX 6650 XT should be a lot (about 157%) better at FSAA than the Radeon R9 290X, and also able to handle higher resolutions without losing too much performance. (explain)

Radeon RX 6650 XT 131520 Mpixels/sec
Radeon R9 290X 51200 Mpixels/sec
Difference: 80320 (157%)

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.

Memory Bandwidth: Memory bandwidth is the maximum amount of data (in units of MB per second) that can be moved past the external memory interface in one second. The number is worked out by multiplying the card's interface width by its memory clock speed. If the card has DDR RAM, the result should be multiplied by 2 once again. If it uses 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 higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied per second. This number is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The better 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 per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
