GeForce 8600 GT 512MB DDR2 vs Radeon RX 6600

Intro

The GeForce 8600 GT 512MB DDR2 has a GPU core clock speed of 540 MHz, and the 512 MB of DDR2 memory is set to run at 400 MHz through a 128-bit bus. It also is comprised of 32 Stream Processors, 16 Texture Address Units, and 8 Raster Operation Units.

Compare those specs to the Radeon RX 6600, which has a core clock speed of 1626 MHz and a GDDR6 memory frequency of 1750 MHz. It also makes use of a 128-bit memory bus, and makes use of a 7 nm design. It is made up of 1792 SPUs, 112 Texture Address Units, and 64 ROPs.

The Radeon RX 6600 should be much (approximately 2008%) faster with regards to texture filtering than the GeForce 8600 GT 512MB DDR2. (explain)

Radeon RX 6600 182112 Mtexels/sec
GeForce 8600 GT 512MB DDR2 8640 Mtexels/sec
Difference: 173472 (2008%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon RX 6600 is superior to the GeForce 8600 GT 512MB DDR2, by a large margin. (explain)

Radeon RX 6600 104064 Mpixels/sec
GeForce 8600 GT 512MB DDR2 4320 Mpixels/sec
Difference: 99744 (2309%)

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 (counted in MB per second) that can be moved past the external memory interface within a second. It's worked out by multiplying the bus width by its memory speed. In the case of DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed per second. This number is calculated by multiplying the total texture units by the core speed of the chip. The better the texel rate, the better the 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 card can possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
