GeForce 8600 GT 256MB DDR2 vs Radeon RX 5600 XT

Intro

Compare all that to the Radeon RX 5600 XT, which has GPU core speed of 1375 MHz, and 6144 MB of GDDR6 memory running at 1500 MHz through a 192-bit bus. It also features 2304 Stream Processors, 144 TAUs, and 64 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 8600 GT 256MB DDR2		47 Watts
Radeon RX 5600 XT		160 Watts
	Difference: 113 Watts (240%)

Memory Bandwidth

Theoretically speaking, the Radeon RX 5600 XT should be a lot faster than the GeForce 8600 GT 256MB DDR2 overall. (explain)

Radeon RX 5600 XT		344064 MB/sec
GeForce 8600 GT 256MB DDR2		12800 MB/sec
	Difference: 331264 (2588%)

Texel Rate

The Radeon RX 5600 XT is quite a bit (more or less 2192%) more effective at anisotropic filtering than the GeForce 8600 GT 256MB DDR2. (explain)

Radeon RX 5600 XT		198000 Mtexels/sec
GeForce 8600 GT 256MB DDR2		8640 Mtexels/sec
	Difference: 189360 (2192%)

Pixel Rate

If using high levels of AA is important to you, then the Radeon RX 5600 XT is a better choice, by far. (explain)

Radeon RX 5600 XT		88000 Mpixels/sec
GeForce 8600 GT 256MB DDR2		4320 Mpixels/sec
	Difference: 83680 (1937%)

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 MB per second) that can be transported over the external memory interface in one second. The number is worked out by multiplying the card's interface width by its memory speed. If it uses DDR type memory, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Render Output Units by the the core 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 rate also depends on lots of 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.
