GeForce 8600 GT 1GB GDDR3 vs Radeon RX 7900 XT

Intro

Compare all that to the Radeon RX 7900 XT, which uses a 5 nm design. AMD has set the core speed at 1500 MHz. The GDDR6 RAM works at a speed of 2500 MHz on this model. It features 5376 SPUs along with 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

Performance-wise, the Radeon RX 7900 XT should theoretically be a lot 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 is quite a bit (more or less 5733%) better 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 is quite a bit (about 6567%) more effective at anti-aliasing than the GeForce 8600 GT 1GB GDDR3, and should be able to handle higher screen resolutions while still performing well. (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 max amount of data (counted in megabytes per second) that can be transferred across the external memory interface within a second. It's worked out by multiplying the card's interface width by its memory speed. If the card has DDR RAM, the result 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 anti-aliasing, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels the video card could possibly write to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
