GeForce 8600 GT 1GB GDDR3 vs Radeon RX 7900 XT

Intro

Compare that to the Radeon RX 7900 XT, which has core speeds of 1500 MHz on the GPU, and 2500 MHz on the 20480 MB of GDDR6 RAM. It features 5376 SPUs along with 336 Texture Address Units 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

As far as performance goes, the Radeon RX 7900 XT should in theory be quite a bit superior to 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 should be quite a bit (approximately 5733%) more effective at anisotropic filtering 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

If running with high levels of AA is important to you, then the Radeon RX 7900 XT is superior to the GeForce 8600 GT 1GB GDDR3, and very much so. (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 information (measured in megabytes per second) that can be transferred past the external memory interface in a second. It's worked out by multiplying the interface width by the speed of its memory. If the card has DDR type RAM, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the card's 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 processed per second. This is worked out by multiplying the total number of texture units by the core speed of the chip. The higher the texel rate, the better the card will be at handling 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 the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
