Radeon R7 250X 2GB vs Radeon RX 5600

Intro

Compare all of that to the Radeon RX 5600, which uses a 7 nm design. AMD has clocked the core speed at 1375 MHz. The GDDR6 memory is set to run at a frequency of 1500 MHz on this particular model. It features 2048 SPUs along with 128 Texture Address Units and 64 Rasterization Operator Units.

	Difference: 222912 (310%)

Texel Rate

The Radeon RX 5600 is quite a bit (more or less 340%) faster with regards to AF than the Radeon R7 250X 2GB. (explain)

Radeon RX 5600		176000 Mtexels/sec
Radeon R7 250X 2GB		40000 Mtexels/sec
	Difference: 136000 (340%)

Pixel Rate

The Radeon RX 5600 will be much (about 450%) better at anti-aliasing than the Radeon R7 250X 2GB, and also able to handle higher 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 max amount of data (measured in MB per second) that can be transferred over the external memory interface within a second. It's calculated by multiplying the bus width by its memory clock speed. If the card has DDR type memory, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly record to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
