GeForce 8600 GT 512MB DDR2 vs Radeon RX 6500 XT

Intro

Compare all that to the Radeon RX 6500 XT, which features a GPU core clock speed of 2200 MHz, and 4096 MB of GDDR6 memory running at 2250 MHz through a 64-bit bus. It also is comprised of 1024 Stream Processors, 64 Texture Address Units, and 32 ROPs.

Radeon RX 6500 XT		107 Watts
	Difference: 60 Watts (128%)

Memory Bandwidth

The Radeon RX 6500 XT should in theory perform much faster than the GeForce 8600 GT 512MB DDR2 in general. (explain)

Radeon RX 6500 XT		147456 MB/sec
GeForce 8600 GT 512MB DDR2		12800 MB/sec
	Difference: 134656 (1052%)

Texel Rate

The Radeon RX 6500 XT should be much (about 1530%) more effective at texture filtering than the GeForce 8600 GT 512MB DDR2. (explain)

Radeon RX 6500 XT		140800 Mtexels/sec
GeForce 8600 GT 512MB DDR2		8640 Mtexels/sec
	Difference: 132160 (1530%)

Pixel Rate

If using a high screen resolution is important to you, then the Radeon RX 6500 XT is the winner, and very much so. (explain)

Radeon RX 6500 XT		70400 Mpixels/sec
GeForce 8600 GT 512MB DDR2		4320 Mpixels/sec
	Difference: 66080 (1530%)

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 information (counted in MB per second) that can be moved across the external memory interface in one second. It is calculated by multiplying the card's interface width by its memory speed. If the card has DDR type RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly record to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount 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 outputting the pixels (image) to the screen. The actual pixel rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
