Radeon R9 280X vs Radeon RX 5600

Intro

Compare all of that to the Radeon RX 5600, which uses a 7 nm design. AMD has set the core frequency at 1375 MHz. The GDDR6 RAM is set to run at a speed of 1500 MHz on this card. 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

Theoretically speaking, the Radeon RX 5600 is 2% faster than the Radeon R9 280X in general, because of its higher data rate. (explain)

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

Texel Rate

The Radeon RX 5600 should be much (approximately 62%) more effective at anisotropic 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 much (more or less 224%) more effective at full screen anti-aliasing than the Radeon R9 280X, and also should be capable of handling higher resolutions without slowing down too much. (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: Memory bandwidth is the largest amount of information (in units of MB per second) that can be moved over the external memory interface in a second. The number is calculated by multiplying the bus width by its memory speed. If the card has DDR RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better 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 amount of texture map elements (texels) that are processed per second. This number is calculated by multiplying the total number of texture units by the core clock speed of the chip. The higher this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
