GeForce 8600 GT 512MB DDR2 vs Radeon RX 5700 XT

Intro

Compare those specifications to the Radeon RX 5700 XT, which features GPU clock speed of 1605 MHz, and 8096 MB of GDDR6 RAM running at 1750 MHz through a 256-bit bus. It also features 2560 Stream Processors, 160 Texture Address Units, and 64 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 8600 GT 512MB DDR2		47 Watts
Radeon RX 5700 XT		225 Watts
	Difference: 178 Watts (379%)

Memory Bandwidth

Theoretically speaking, the Radeon RX 5700 XT is 3484% quicker than the GeForce 8600 GT 512MB DDR2 in general, because of its greater bandwidth. (explain)

Radeon RX 5700 XT		458752 MB/sec
GeForce 8600 GT 512MB DDR2		12800 MB/sec
	Difference: 445952 (3484%)

Texel Rate

The Radeon RX 5700 XT will be a lot (more or less 2872%) more effective at texture filtering than the GeForce 8600 GT 512MB DDR2. (explain)

Radeon RX 5700 XT		256800 Mtexels/sec
GeForce 8600 GT 512MB DDR2		8640 Mtexels/sec
	Difference: 248160 (2872%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon RX 5700 XT is a better choice, and very much so. (explain)

Radeon RX 5700 XT		102720 Mpixels/sec
GeForce 8600 GT 512MB DDR2		4320 Mpixels/sec
	Difference: 98400 (2278%)

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 data (counted in MB per second) that can be transferred across the external memory interface within a second. It's calculated by multiplying the card's interface width by its memory speed. If the card has DDR type memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed in one second. This is worked out by multiplying the total amount of texture units of the card 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 per second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of colour ROPs by the the core 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 many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
