Radeon R7 250X vs Radeon RX 5600

Intro

Compare all that to the Radeon RX 5600, which uses a 7 nm design. AMD has clocked the core speed at 1375 MHz. The GDDR6 memory runs at a speed of 1500 MHz on this card. It features 2048 SPUs as well as 128 Texture Address Units and 64 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon R7 250X		95 Watts
Radeon RX 5600		150 Watts
	Difference: 55 Watts (58%)

Memory Bandwidth

Theoretically speaking, the Radeon RX 5600 should perform quite a bit faster than the Radeon R7 250X overall. (explain)

Radeon RX 5600		294912 MB/sec
Radeon R7 250X		72000 MB/sec
	Difference: 222912 (310%)

Texel Rate

The Radeon RX 5600 will be a lot (approximately 340%) better at texture filtering than the Radeon R7 250X. (explain)

Radeon RX 5600		176000 Mtexels/sec
Radeon R7 250X		40000 Mtexels/sec
	Difference: 136000 (340%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon RX 5600 is the winner, by a large margin. (explain)

Radeon RX 5600		88000 Mpixels/sec
Radeon R7 250X		16000 Mpixels/sec
	Difference: 72000 (450%)

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 largest amount of information (measured in megabytes per second) that can be transferred across the external memory interface in a second. The number is calculated by multiplying the card's bus width by its memory clock speed. In the case of DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the better 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 per second. This figure is calculated by multiplying the total number of texture units by the core 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 in one second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly record to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
