GeForce 8600 GT 1GB DDR2 vs Radeon RX 6650 XT

Intro

Compare all of that to the Radeon RX 6650 XT, which features GPU clock speed of 2055 MHz, and 8192 MB of GDDR6 memory running at 2190 MHz through a 128-bit bus. It also features 2048 Stream Processors, 128 Texture Address Units, and 64 Raster Operation Units.

GeForce 8600 GT 1GB DDR2		12800 MB/sec
	Difference: 274272 (2143%)

Texel Rate

The Radeon RX 6650 XT is much (more or less 2944%) more effective at texture filtering than the GeForce 8600 GT 1GB DDR2. (explain)

Radeon RX 6650 XT		263040 Mtexels/sec
GeForce 8600 GT 1GB DDR2		8640 Mtexels/sec
	Difference: 254400 (2944%)

Pixel Rate

If using high levels of AA is important to you, then the Radeon RX 6650 XT is a better choice, by far. (explain)

Radeon RX 6650 XT		131520 Mpixels/sec
GeForce 8600 GT 1GB DDR2		4320 Mpixels/sec
	Difference: 127200 (2944%)

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 transferred past the external memory interface in a second. It is worked out by multiplying the card's interface width by its memory clock speed. If it uses DDR type memory, it 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 anti-aliasing, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly write to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
