GeForce 8600 GT 512MB DDR2 vs Radeon RX 6650 XT

Intro

Compare all that to the Radeon RX 6650 XT, which features GPU core speed of 2055 MHz, and 8192 MB of GDDR6 memory set to run at 2190 MHz through a 128-bit bus. It also features 2048 Stream Processors, 128 TAUs, and 64 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 8600 GT 512MB DDR2		47 Watts
Radeon RX 6650 XT		176 Watts
	Difference: 129 Watts (274%)

Memory Bandwidth

In theory, the Radeon RX 6650 XT will be 2143% quicker than the GeForce 8600 GT 512MB DDR2 in general, due to its higher data rate. (explain)

Radeon RX 6650 XT		287072 MB/sec
GeForce 8600 GT 512MB DDR2		12800 MB/sec
	Difference: 274272 (2143%)

Texel Rate

The Radeon RX 6650 XT should be quite a bit (more or less 2944%) faster with regards to AF than the GeForce 8600 GT 512MB DDR2. (explain)

Radeon RX 6650 XT		263040 Mtexels/sec
GeForce 8600 GT 512MB DDR2		8640 Mtexels/sec
	Difference: 254400 (2944%)

Pixel Rate

If using a high screen resolution is important to you, then the Radeon RX 6650 XT is the winner, and very much so. (explain)

Radeon RX 6650 XT		131520 Mpixels/sec
GeForce 8600 GT 512MB DDR2		4320 Mpixels/sec
	Difference: 127200 (2944%)

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 max amount of information (in units of megabytes per second) that can be moved past the external memory interface in a second. It is calculated by multiplying the card's bus width by its memory speed. In the case of DDR memory, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel 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 max fill rate.
