Compare any two graphics cards:

Radeon HD 7950 vs Radeon RX 5500

Intro

The Radeon HD 7950 has clock speeds of 800 MHz on the GPU, and 1250 MHz on the 1536 MB of GDDR5 RAM. It features 1792 SPUs as well as 112 TAUs and 32 ROPs.

Compare those specs to the Radeon RX 5500, which features a GPU core clock speed of 1670 MHz, and 4096 MB of GDDR6 RAM running at 14000 MHz through a 128-bit bus. It also is made up of 1408 Stream Processors, 88 Texture Address Units, and 32 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 5500		150 Watts
Radeon HD 7950		200 Watts
	Difference: 50 Watts (33%)

Memory Bandwidth

In theory, the Radeon HD 7950 should be 5% faster than the Radeon RX 5500 overall, because of its higher data rate. (explain)

Radeon HD 7950		240000 MB/sec
Radeon RX 5500		229376 MB/sec
	Difference: 10624 (5%)

Texel Rate

The Radeon RX 5500 will be quite a bit (about 64%) more effective at anisotropic filtering than the Radeon HD 7950. (explain)

Radeon RX 5500		146960 Mtexels/sec
Radeon HD 7950		89600 Mtexels/sec
	Difference: 57360 (64%)

Pixel Rate

The Radeon RX 5500 is quite a bit (more or less 109%) faster with regards to AA than the Radeon HD 7950, and able to handle higher screen resolutions without losing too much performance. (explain)

Radeon RX 5500		53440 Mpixels/sec
Radeon HD 7950		25600 Mpixels/sec
	Difference: 27840 (109%)

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 maximum amount of data (counted in MB per second) that can be transported across the external memory interface within a second. The number is calculated by multiplying the card's interface width by the speed of its memory. If the card has DDR memory, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed per second. This number is calculated 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 texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the most pixels the video card could possibly record to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
