Radeon HD 6950 vs Radeon RX 6500 XT

Intro

The Radeon HD 6950 has a clock frequency of 800 MHz and a GDDR5 memory speed of 1250 MHz. It also features a 256-bit memory bus, and makes use of a 40 nm design. It features 1408 SPUs, 88 TAUs, and 32 Raster Operation Units.

Compare those specifications to the Radeon RX 6500 XT, which comes with GPU core speed of 2200 MHz, and 4096 MB of GDDR6 memory set to run at 2250 MHz through a 64-bit bus. It also features 1024 Stream Processors, 64 TAUs, and 32 Raster Operation Units.

Theoretically speaking, the Radeon HD 6950 will be 9% faster than the Radeon RX 6500 XT in general, due to its higher bandwidth. (explain)

Radeon HD 6950 160000 MB/sec
Radeon RX 6500 XT 147456 MB/sec
Difference: 12544 (9%)

Texel Rate

The Radeon RX 6500 XT is much (approximately 100%) more effective at texture filtering than the Radeon HD 6950. (explain)

Radeon RX 6500 XT 140800 Mtexels/sec
Radeon HD 6950 70400 Mtexels/sec
Difference: 70400 (100%)

Pixel Rate

If running with high levels of AA is important to you, then the Radeon RX 6500 XT is a better choice, by a large margin. (explain)

Radeon RX 6500 XT 70400 Mpixels/sec
Radeon HD 6950 25600 Mpixels/sec
Difference: 44800 (175%)

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: Bandwidth is the max amount of information (in units of megabytes per second) that can be transported across the external memory interface within a second. It is worked out by multiplying the interface width by its memory speed. If it uses DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, 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 number is calculated by multiplying the total number of texture units by the core speed of the chip. The higher the texel rate, the better the 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 record to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
