Radeon HD 7870 XT vs Radeon RX 6600

Intro

The Radeon HD 7870 XT has a GPU core speed of 925 MHz, and the 2048 MB of GDDR5 RAM is set to run at 1500 MHz through a 256-bit bus. It also is made up of 1536 Stream Processors, 96 Texture Address Units, and 32 ROPs.

Compare those specifications to the Radeon RX 6600, which makes use of a 7 nm design. AMD has set the core speed at 1626 MHz. The GDDR6 memory works at a frequency of 1750 MHz on this particular card. It features 1792 SPUs along with 112 Texture Address Units and 64 Rasterization Operator Units.

Radeon HD 7870 XT 192000 MB/sec
Difference: 37376 (19%)

Texel Rate

The Radeon RX 6600 is a lot (about 105%) better at anisotropic filtering than the Radeon HD 7870 XT. (explain)

Radeon RX 6600 182112 Mtexels/sec
Radeon HD 7870 XT 88800 Mtexels/sec
Difference: 93312 (105%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon RX 6600 is a better choice, and very much so. (explain)

Radeon RX 6600 104064 Mpixels/sec
Radeon HD 7870 XT 29600 Mpixels/sec
Difference: 74464 (252%)

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 largest amount of information (measured in MB per second) that can be moved over the external memory interface in a second. It is worked out by multiplying the card's bus width by its memory speed. If the card has DDR type memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed in one second. This is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate 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 outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
