Radeon R7 250X 2GB vs Radeon RX 5600

Intro

Compare all of that to the Radeon RX 5600, which has GPU core speed of 1375 MHz, and 6144 MB of GDDR6 RAM running at 1500 MHz through a 192-bit bus. It also features 2048 Stream Processors, 128 TAUs, and 64 ROPs.

Pixel Rate

The Radeon RX 5600 will be quite a bit (approximately 450%) better at AA than the Radeon R7 250X 2GB, and also able to handle higher screen resolutions without losing too much performance. (explain)

Radeon RX 5600		88000 Mpixels/sec
Radeon R7 250X 2GB		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: Memory bandwidth is the maximum amount of data (measured in MB per second) that can be moved across the external memory interface in one second. It's calculated by multiplying the card's interface width by the speed of its memory. If it uses DDR memory, the result should 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 anti-aliasing, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly write to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
