VS

Radeon HD 7950 3GB vs Radeon RX 6600 XT

Intro

The Radeon HD 7950 3GB comes with core clock speeds of 800 MHz on the GPU, and 1250 MHz on the 3072 MB of GDDR5 RAM. It features 1792 SPUs as well as 112 TAUs and 32 ROPs.

Compare that to the Radeon RX 6600 XT, which features core clock speeds of 1968 MHz on the GPU, and 2000 MHz on the 8192 MB of GDDR6 RAM. It features 2048 SPUs as well as 128 Texture Address Units and 64 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 6600 XT 160 Watts
Radeon HD 7950 3GB 200 Watts
Difference: 40 Watts (25%)

Memory Bandwidth

In theory, the Radeon RX 6600 XT should perform just a bit faster than the Radeon HD 7950 3GB overall. (explain)

Radeon RX 6600 XT 262144 MB/sec
Radeon HD 7950 3GB 240000 MB/sec
Difference: 22144 (9%)

Texel Rate

The Radeon RX 6600 XT should be much (about 181%) faster with regards to anisotropic filtering than the Radeon HD 7950 3GB. (explain)

Radeon RX 6600 XT 251904 Mtexels/sec
Radeon HD 7950 3GB 89600 Mtexels/sec
Difference: 162304 (181%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon RX 6600 XT is a better choice, and very much so. (explain)

Radeon RX 6600 XT 125952 Mpixels/sec
Radeon HD 7950 3GB 25600 Mpixels/sec
Difference: 100352 (392%)

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 max amount of information (counted in megabytes per second) that can be moved past the external memory interface in one second. It's calculated by multiplying the card's bus width by its memory clock speed. If the card has DDR type RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed in one second. This figure is worked out by multiplying the total texture units by the core clock speed of the chip. The higher the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
