Radeon R9 280 vs Radeon RX 6600

Intro

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

Memory Bandwidth

Theoretically speaking, the Radeon R9 280 should be a small bit faster than the Radeon RX 6600 in general. (explain)

Radeon R9 280		240000 MB/sec
Radeon RX 6600		229376 MB/sec
	Difference: 10624 (5%)

Texel Rate

The Radeon RX 6600 should be quite a bit (about 74%) better at AF than the Radeon R9 280. (explain)

Radeon RX 6600		182112 Mtexels/sec
Radeon R9 280		104496 Mtexels/sec
	Difference: 77616 (74%)

Pixel Rate

If running with high levels of AA is important to you, then the Radeon RX 6600 is the winner, by far. (explain)

Radeon RX 6600		104064 Mpixels/sec
Radeon R9 280		29856 Mpixels/sec
	Difference: 74208 (249%)

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 max amount of data (counted in megabytes per second) that can be transported past the external memory interface in one second. The number is worked out by multiplying the bus width by the speed of its memory. If it uses DDR type RAM, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, 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 figure is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly write to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Raster Operations Pipelines by the the card's clock speed. 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 fill rate is also dependant on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
