Radeon R9 280 vs Radeon RX 5500 XT

Intro

The Radeon R9 280 features core clock speeds of 933 MHz on the GPU, and 1250 MHz on the 3072 MB of GDDR5 RAM. It features 1792 SPUs along with 112 TAUs and 32 ROPs.

Compare those specs to the Radeon RX 5500 XT, which uses a 7 nm design. AMD has clocked the core speed at 1717 MHz. The GDDR6 RAM is set to run at a frequency of 1750 MHz on this specific card. It features 1408 SPUs as well as 88 Texture Address Units and 32 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 5500 XT 130 Watts
Radeon R9 280 250 Watts
Difference: 120 Watts (92%)

Memory Bandwidth

In theory, the Radeon R9 280 should be 5% faster than the Radeon RX 5500 XT overall, because of its greater data rate. (explain)

Radeon R9 280 240000 MB/sec
Radeon RX 5500 XT 229376 MB/sec
Difference: 10624 (5%)

Texel Rate

The Radeon RX 5500 XT is much (about 45%) better at texture filtering than the Radeon R9 280. (explain)

Radeon RX 5500 XT 151096 Mtexels/sec
Radeon R9 280 104496 Mtexels/sec
Difference: 46600 (45%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon RX 5500 XT is superior to the Radeon R9 280, and very much so. (explain)

Radeon RX 5500 XT 54944 Mpixels/sec
Radeon R9 280 29856 Mpixels/sec
Difference: 25088 (84%)

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 information (counted in megabytes per second) that can be moved past the external memory interface in a second. It's calculated by multiplying the interface width by the speed of its memory. If it uses DDR type memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels the video card could possibly record to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
