GeForce 8800 GT 512MB vs Radeon RX 6650 XT

Intro

Compare all that to the Radeon RX 6650 XT, which uses a 7 nm design. AMD has set the core speed at 2055 MHz. The GDDR6 RAM is set to run at a frequency of 2190 MHz on this particular model. It features 2048 SPUs as well as 128 TAUs and 64 Rasterization Operator Units.

The Radeon RX 6650 XT should in theory perform a lot faster than the GeForce 8800 GT 512MB in general. (explain)

Radeon RX 6650 XT		287072 MB/sec
GeForce 8800 GT 512MB		57600 MB/sec
	Difference: 229472 (398%)

Texel Rate

The Radeon RX 6650 XT will be quite a bit (approximately 683%) faster with regards to texture filtering than the GeForce 8800 GT 512MB. (explain)

Radeon RX 6650 XT		263040 Mtexels/sec
GeForce 8800 GT 512MB		33600 Mtexels/sec
	Difference: 229440 (683%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon RX 6650 XT is superior to the GeForce 8800 GT 512MB, by a large margin. (explain)

Radeon RX 6650 XT		131520 Mpixels/sec
GeForce 8800 GT 512MB		9600 Mpixels/sec
	Difference: 121920 (1270%)

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 largest amount of data (measured in MB per second) that can be moved across the external memory interface in one second. It's calculated by multiplying the bus width by its memory speed. If the card has DDR RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, 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 texture map elements (texels) that are processed in one second. This figure is worked out by multiplying the total amount of texture units by the core speed of the chip. The better this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly record to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
