Radeon HD 7950 vs Radeon RX 5500 XT

Intro

Compare those specifications to the Radeon RX 5500 XT, which uses a 7 nm design. AMD has clocked the core frequency at 1717 MHz. The GDDR6 memory is set to run at a frequency of 1750 MHz on this specific card. It features 1408 SPUs along with 88 TAUs and 32 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 5500 XT		130 Watts
Radeon HD 7950		200 Watts
	Difference: 70 Watts (54%)

Memory Bandwidth

Theoretically speaking, the Radeon HD 7950 should be a little bit faster than the Radeon RX 5500 XT in general. (explain)

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

Texel Rate

The Radeon RX 5500 XT should be a lot (about 69%) faster with regards to anisotropic filtering than the Radeon HD 7950. (explain)

Radeon RX 5500 XT		151096 Mtexels/sec
Radeon HD 7950		89600 Mtexels/sec
	Difference: 61496 (69%)

Pixel Rate

If running with high levels of AA is important to you, then the Radeon RX 5500 XT is superior to the Radeon HD 7950, and very much so. (explain)

Radeon RX 5500 XT		54944 Mpixels/sec
Radeon HD 7950		25600 Mpixels/sec
	Difference: 29344 (115%)

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.

Specifications

Memory Bandwidth: Bandwidth is the maximum amount of data (measured in megabytes per second) that can be moved over 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 type memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Raster Operations Pipelines by the clock 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 rate also depends on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
