GeForce 8600 GT 1GB DDR2 vs Radeon RX 6650 XT

Intro

Compare those specifications to the Radeon RX 6650 XT, which makes use of a 7 nm design. AMD has clocked the core frequency at 2055 MHz. The GDDR6 memory is set to run at a speed of 2190 MHz on this particular card. It features 2048 SPUs along with 128 TAUs and 64 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 8600 GT 1GB 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% faster than the GeForce 8600 GT 1GB DDR2 overall, due to its greater bandwidth. (explain)

Radeon RX 6650 XT		287072 MB/sec
GeForce 8600 GT 1GB DDR2		12800 MB/sec
	Difference: 274272 (2143%)

Texel Rate

The Radeon RX 6650 XT should be quite a bit (approximately 2944%) more effective at texture filtering than the GeForce 8600 GT 1GB DDR2. (explain)

Radeon RX 6650 XT		263040 Mtexels/sec
GeForce 8600 GT 1GB DDR2		8640 Mtexels/sec
	Difference: 254400 (2944%)

Pixel Rate

The Radeon RX 6650 XT is a lot (approximately 2944%) better at FSAA than the GeForce 8600 GT 1GB DDR2, and should be capable of handling higher screen resolutions better. (explain)

Radeon RX 6650 XT		131520 Mpixels/sec
GeForce 8600 GT 1GB 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 maximum amount of data (in units of MB per second) that can be transferred past the external memory interface within a second. It is calculated by multiplying the card's interface width by the speed of its memory. If it uses DDR type memory, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the memory bandwidth, 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 number of texture map elements (texels) that are applied per second. This is calculated 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 card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
