GeForce 8800 GT 512MB vs Radeon RX 6650 XT

Intro

The GeForce 8800 GT 512MB uses a 65 nm design. nVidia has set the core speed at 600 MHz. The GDDR3 memory is set to run at a frequency of 900 MHz on this particular card. It features 112 SPUs as well as 56 TAUs and 16 ROPs.

Compare all of that to the Radeon RX 6650 XT, which comes with a GPU core clock speed of 2055 MHz, and 8192 MB of GDDR6 RAM running at 2190 MHz through a 128-bit bus. It also features 2048 Stream Processors, 128 Texture Address Units, and 64 Raster Operation Units.

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

Texel Rate

The Radeon RX 6650 XT is a lot (more or less 683%) faster with regards to anisotropic 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 a high resolution is important to you, then the Radeon RX 6650 XT is a better choice, and very much so. (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.

Memory Bandwidth: Memory bandwidth is the largest amount of information (measured in MB per second) that can be transported across the external memory interface in one second. It's worked out by multiplying the interface width by the speed of its memory. In the case of DDR RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly write to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
