GeForce 8600 GT 1GB DDR2 vs Radeon RX 7900 XTX

Intro

Compare all of that to the Radeon RX 7900 XTX, which has GPU clock speed of 1855 MHz, and 24576 MB of GDDR6 memory running at 2500 MHz through a 384-bit bus. It also is made up of 6144 Stream Processors, 384 Texture Address Units, and 192 Raster Operation Units.

Pixel Rate

The Radeon RX 7900 XTX will be quite a bit (about 8144%) more effective at full screen anti-aliasing than the GeForce 8600 GT 1GB DDR2, and also will be able to handle higher resolutions while still performing well. (explain)

Radeon RX 7900 XTX		356160 Mpixels/sec
GeForce 8600 GT 1GB DDR2		4320 Mpixels/sec
	Difference: 351840 (8144%)

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: Memory bandwidth is the max amount of data (counted in MB per second) that can be transported over the external memory interface in one second. It's worked out by multiplying the card's interface width by its memory speed. If it uses DDR type RAM, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied per second. This is worked out by multiplying the total amount 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 that the graphics chip can possibly record to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
