GeForce 8600 GT 512MB DDR2 vs Radeon RX 7900 XT

Intro

Compare those specifications to the Radeon RX 7900 XT, which comes with GPU clock speed of 1500 MHz, and 20480 MB of GDDR6 RAM set to run at 2500 MHz through a 320-bit bus. It also is made up of 5376 SPUs, 336 TAUs, and 192 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 8600 GT 512MB DDR2		47 Watts
Radeon RX 7900 XT		300 Watts
	Difference: 253 Watts (538%)

Memory Bandwidth

Theoretically speaking, the Radeon RX 7900 XT should be 6300% faster than the GeForce 8600 GT 512MB DDR2 in general, because of its greater bandwidth. (explain)

Radeon RX 7900 XT		819200 MB/sec
GeForce 8600 GT 512MB DDR2		12800 MB/sec
	Difference: 806400 (6300%)

Texel Rate

The Radeon RX 7900 XT should be a lot (approximately 5733%) faster with regards to texture filtering than the GeForce 8600 GT 512MB DDR2. (explain)

Radeon RX 7900 XT		504000 Mtexels/sec
GeForce 8600 GT 512MB DDR2		8640 Mtexels/sec
	Difference: 495360 (5733%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon RX 7900 XT is superior to the GeForce 8600 GT 512MB DDR2, by far. (explain)

Radeon RX 7900 XT		288000 Mpixels/sec
GeForce 8600 GT 512MB DDR2		4320 Mpixels/sec
	Difference: 283680 (6567%)

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 information (measured in megabytes per second) that can be transported across the external memory interface in a second. It's worked out by multiplying the bus 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 ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly record to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
