GeForce 8600 GT 1GB GDDR3 vs Radeon RX 7900 XT

Intro

Compare those specifications to the Radeon RX 7900 XT, which makes use of a 5 nm design. AMD has clocked the core speed at 1500 MHz. The GDDR6 memory runs at a speed of 2500 MHz on this particular model. It features 5376 SPUs as well as 336 TAUs and 192 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 8600 GT 1GB GDDR3		47 Watts
Radeon RX 7900 XT		300 Watts
	Difference: 253 Watts (538%)

Memory Bandwidth

The Radeon RX 7900 XT, in theory, should be quite a bit faster than the GeForce 8600 GT 1GB GDDR3 in general. (explain)

Radeon RX 7900 XT		819200 MB/sec
GeForce 8600 GT 1GB GDDR3		22400 MB/sec
	Difference: 796800 (3557%)

Texel Rate

The Radeon RX 7900 XT will be much (approximately 5733%) more effective at AF than the GeForce 8600 GT 1GB GDDR3. (explain)

Radeon RX 7900 XT		504000 Mtexels/sec
GeForce 8600 GT 1GB GDDR3		8640 Mtexels/sec
	Difference: 495360 (5733%)

Pixel Rate

The Radeon RX 7900 XT will be much (more or less 6567%) better at anti-aliasing than the GeForce 8600 GT 1GB GDDR3, and should be capable of handling higher screen resolutions without slowing down too much. (explain)

Radeon RX 7900 XT		288000 Mpixels/sec
GeForce 8600 GT 1GB GDDR3		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: Memory bandwidth is the maximum amount of data (counted in megabytes per second) that can be transported over the external memory interface in one second. The number is worked out by multiplying the card's bus width by its memory speed. If it uses DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

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