Compare any two graphics cards:
VS

Radeon HD 5970 vs Radeon RX 6500 XT

Intro

The Radeon HD 5970 features core speeds of 725 MHz on the GPU, and 1000 MHz on the 1024 MB of GDDR5 RAM. It features 1600 SPUs as well as 160 TAUs and 64 Rasterization Operator Units.

Compare that to the Radeon RX 6500 XT, which has GPU clock speed of 2200 MHz, and 4096 MB of GDDR6 RAM running at 2250 MHz through a 64-bit bus. It also is made up of 1024 Stream Processors, 64 Texture Address Units, and 32 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 6500 XT 107 Watts
Radeon HD 5970 294 Watts
Difference: 187 Watts (175%)

Memory Bandwidth

Theoretically speaking, the Radeon HD 5970 should be 74% quicker than the Radeon RX 6500 XT overall, because of its higher data rate. (explain)

Radeon HD 5970 256000 MB/sec
Radeon RX 6500 XT 147456 MB/sec
Difference: 108544 (74%)

Texel Rate

The Radeon HD 5970 is a lot (about 65%) better at texture filtering than the Radeon RX 6500 XT. (explain)

Radeon HD 5970 232000 Mtexels/sec
Radeon RX 6500 XT 140800 Mtexels/sec
Difference: 91200 (65%)

Pixel Rate

If using a high screen resolution is important to you, then the Radeon HD 5970 is superior to the Radeon RX 6500 XT, by far. (explain)

Radeon HD 5970 92800 Mpixels/sec
Radeon RX 6500 XT 70400 Mpixels/sec
Difference: 22400 (32%)

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.

One or more cards in this comparison are multi-core. This means that their bandwidth, texel and pixel rates are theoretically doubled - this does not mean the card will actually perform twice as fast, but only that it should in theory be able to. Actual game benchmarks will give a more accurate idea of what it's capable of.

Memory Bandwidth: Bandwidth is the largest amount of information (in units of MB per second) that can be transported across the external memory interface in one second. It's calculated by multiplying the bus width by the speed of its memory. If it uses DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster 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 amount of texture map elements (texels) that are processed per second. This 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 video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
