Radeon R9 M290X vs Radeon RX 6900 XT

Intro

Compare all of that to the Radeon RX 6900 XT, which has a GPU core clock speed of 1825 MHz, and 16384 MB of GDDR6 RAM running at 2000 MHz through a 256-bit bus. It also is made up of 5120 Stream Processors, 320 TAUs, and 128 ROPs.

Texel Rate

The Radeon RX 6900 XT is quite a bit (approximately 759%) more effective at texture filtering than the Radeon R9 M290X. (explain)

Radeon RX 6900 XT		584000 Mtexels/sec
Radeon R9 M290X		68000 Mtexels/sec
	Difference: 516000 (759%)

Pixel Rate

If running with high levels of AA is important to you, then the Radeon RX 6900 XT is superior to the Radeon R9 M290X, and very much so. (explain)

Radeon RX 6900 XT		233600 Mpixels/sec
Radeon R9 M290X		27200 Mpixels/sec
	Difference: 206400 (759%)

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 data (counted in megabytes per second) that can be transported over the external memory interface in one second. It is calculated by multiplying the card's bus width by the speed of its memory. If the card has DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the 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 number of texture map elements (texels) that are processed in one second. This figure is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The better this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per 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 number is calculated by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output 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 reach the max fill rate.
