Radeon R7 250X vs Radeon RX 5500

Intro

Compare all that to the Radeon RX 5500, which makes use of a 7 nm design. AMD has clocked the core speed at 1670 MHz. The GDDR6 memory works at a speed of 1750 MHz on this specific model. It features 1408 SPUs as well as 88 Texture Address Units and 32 ROPs.

Radeon R7 250X		72000 MB/sec
	Difference: 157376 (219%)

Texel Rate

The Radeon RX 5500 should be a lot (approximately 267%) faster with regards to anisotropic filtering than the Radeon R7 250X. (explain)

Radeon RX 5500		146960 Mtexels/sec
Radeon R7 250X		40000 Mtexels/sec
	Difference: 106960 (267%)

Pixel Rate

If running with a high resolution is important to you, then the Radeon RX 5500 is a better choice, and very much so. (explain)

Radeon RX 5500		53440 Mpixels/sec
Radeon R7 250X		16000 Mpixels/sec
	Difference: 37440 (234%)

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 data (in units of MB per second) that can be moved past the external memory interface in a second. It is calculated by multiplying the interface width by its memory clock speed. In the case of DDR RAM, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly record to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
