Radeon R7 250 vs Radeon RX 5600

Intro

Compare those specifications to the Radeon RX 5600, which has clock speeds of 1375 MHz on the GPU, and 1500 MHz on the 6144 MB of GDDR6 RAM. It features 2048 SPUs as well as 128 TAUs and 64 Rasterization Operator Units.

Radeon R7 250		65 Watts
Radeon RX 5600		150 Watts
	Difference: 85 Watts (131%)

Memory Bandwidth

Theoretically, the Radeon RX 5600 should be a lot faster than the Radeon R7 250 in general. (explain)

Radeon RX 5600		294912 MB/sec
Radeon R7 250		73600 MB/sec
	Difference: 221312 (301%)

Texel Rate

The Radeon RX 5600 is quite a bit (about 633%) better at anisotropic filtering than the Radeon R7 250. (explain)

Radeon RX 5600		176000 Mtexels/sec
Radeon R7 250		24000 Mtexels/sec
	Difference: 152000 (633%)

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 250		8000 Mpixels/sec
	Difference: 80000 (1000%)

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 information (measured in MB per second) that can be transported over the external memory interface in a second. It's calculated by multiplying the interface width by the speed of its memory. If it uses DDR RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed 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 higher the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly write to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
