GeForce 8600 GT 1GB GDDR3 vs Radeon RX 6600

Intro

Compare those specifications to the Radeon RX 6600, which makes use of a 7 nm design. AMD has clocked the core speed at 1626 MHz. The GDDR6 memory works at a speed of 1750 MHz on this card. It features 1792 SPUs as well as 112 TAUs and 64 Rasterization Operator Units.

Radeon RX 6600		132 Watts
	Difference: 85 Watts (181%)

Memory Bandwidth

The Radeon RX 6600, in theory, should be quite a bit faster than the GeForce 8600 GT 1GB GDDR3 overall. (explain)

Radeon RX 6600		229376 MB/sec
GeForce 8600 GT 1GB GDDR3		22400 MB/sec
	Difference: 206976 (924%)

Texel Rate

The Radeon RX 6600 should be quite a bit (about 2008%) better at AF than the GeForce 8600 GT 1GB GDDR3. (explain)

Radeon RX 6600		182112 Mtexels/sec
GeForce 8600 GT 1GB GDDR3		8640 Mtexels/sec
	Difference: 173472 (2008%)

Pixel Rate

The Radeon RX 6600 is much (approximately 2309%) more effective at AA than the GeForce 8600 GT 1GB GDDR3, and also will be capable of handling higher screen resolutions more effectively. (explain)

Radeon RX 6600		104064 Mpixels/sec
GeForce 8600 GT 1GB GDDR3		4320 Mpixels/sec
	Difference: 99744 (2309%)

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 maximum amount of data (in units of MB per second) that can be transported across the external memory interface within a second. The number is calculated by multiplying the card's interface width by its memory clock speed. In the case of DDR RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly record to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of Raster Operations Pipelines by the the core clock speed. 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 lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
