Radeon R7 250X vs Radeon RX 5700

Intro

Compare those specs to the Radeon RX 5700, which has core speeds of 1465 MHz on the GPU, and 1750 MHz on the 8096 MB of GDDR6 memory. It features 2304 SPUs as well as 144 TAUs and 64 ROPs.

Radeon R7 250X		95 Watts
Radeon RX 5700		180 Watts
	Difference: 85 Watts (89%)

Memory Bandwidth

The Radeon RX 5700 should in theory be much faster than the Radeon R7 250X in general. (explain)

Radeon RX 5700		458752 MB/sec
Radeon R7 250X		72000 MB/sec
	Difference: 386752 (537%)

Texel Rate

The Radeon RX 5700 should be quite a bit (more or less 427%) better at texture filtering than the Radeon R7 250X. (explain)

Radeon RX 5700		210960 Mtexels/sec
Radeon R7 250X		40000 Mtexels/sec
	Difference: 170960 (427%)

Pixel Rate

If running with a high resolution is important to you, then the Radeon RX 5700 is a better choice, by far. (explain)

Radeon RX 5700		93760 Mpixels/sec
Radeon R7 250X		16000 Mpixels/sec
	Difference: 77760 (486%)

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 maximum amount of information (measured in megabytes per second) that can be transported past the external memory interface in one 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 once again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster 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 figure is calculated by multiplying the total texture units of the card by the core 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 applied in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly write to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
