Radeon R9 280X vs Radeon RX 5600

Intro

Compare all of that to the Radeon RX 5600, which features clock speeds of 1375 MHz on the GPU, and 1500 MHz on the 6144 MB of GDDR6 memory. It features 2048 SPUs along with 128 Texture Address Units and 64 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 5600		150 Watts
Radeon R9 280X		250 Watts
	Difference: 100 Watts (67%)

Memory Bandwidth

In theory, the Radeon RX 5600 should be 2% faster than the Radeon R9 280X overall, because of its greater bandwidth. (explain)

Radeon RX 5600		294912 MB/sec
Radeon R9 280X		288000 MB/sec
	Difference: 6912 (2%)

Texel Rate

The Radeon RX 5600 should be quite a bit (about 62%) faster with regards to texture filtering than the Radeon R9 280X. (explain)

Radeon RX 5600		176000 Mtexels/sec
Radeon R9 280X		108800 Mtexels/sec
	Difference: 67200 (62%)

Pixel Rate

The Radeon RX 5600 will be a lot (about 224%) more effective at AA than the Radeon R9 280X, and should be able to handle higher resolutions without losing too much performance. (explain)

Radeon RX 5600		88000 Mpixels/sec
Radeon R9 280X		27200 Mpixels/sec
	Difference: 60800 (224%)

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 max amount of information (in units of MB per second) that can be transferred across the external memory interface within a second. The number is worked out by multiplying the card's interface width by its memory speed. If it uses DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. 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 high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly write to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of colour ROPs by the the core 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 output rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
