GeForce 8600 GT 512MB DDR2 vs Radeon RX 6650 XT

Intro

Compare those specifications to the Radeon RX 6650 XT, which uses a 7 nm design. AMD has clocked the core frequency at 2055 MHz. The GDDR6 RAM runs at a speed of 2190 MHz on this specific card. It features 2048 SPUs along with 128 Texture Address Units and 64 Rasterization Operator 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

As far as performance goes, the Radeon RX 6650 XT should in theory be quite a bit superior to the GeForce 8600 GT 512MB DDR2 in general. (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 will be quite a bit (approximately 2944%) more effective at texture filtering 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 lots of anti-aliasing 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: Memory bandwidth is the max amount of data (in units of MB per second) that can be transferred past the external memory interface in a second. It's worked out by multiplying the bus width by its memory speed. If the card has DDR type RAM, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, 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 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 maximum number of pixels the video card could possibly write to its 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 clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
