Radeon R9 290 vs Radeon RX 6600

Intro

Compare all of that to the Radeon RX 6600, which has core speeds of 1626 MHz on the GPU, and 1750 MHz on the 8192 MB of GDDR6 memory. It features 1792 SPUs along with 112 TAUs and 64 Rasterization Operator Units.

Radeon RX 6600		229376 MB/sec
	Difference: 90624 (40%)

Texel Rate

The Radeon RX 6600 is much (about 42%) faster with regards to anisotropic filtering than the Radeon R9 290. (explain)

Radeon RX 6600		182112 Mtexels/sec
Radeon R9 290		128000 Mtexels/sec
	Difference: 54112 (42%)

Pixel Rate

The Radeon RX 6600 will be quite a bit (more or less 103%) faster with regards to AA than the Radeon R9 290, and should be able to handle higher resolutions without slowing down too much. (explain)

Radeon RX 6600		104064 Mpixels/sec
Radeon R9 290		51200 Mpixels/sec
	Difference: 52864 (103%)

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: Memory bandwidth is the maximum amount of information (measured in MB per second) that can be transported past the external memory interface in one second. It is calculated by multiplying the bus width by its memory clock speed. If the card has DDR type RAM, 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 are applied in one second. This is worked out by multiplying the total texture units by the core speed of the chip. The higher the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly record to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs by the the core 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 lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
