Radeon R7 250X vs Radeon RX 5500

Intro

Compare all that to the Radeon RX 5500, which has a GPU core clock speed of 1670 MHz, and 4096 MB of GDDR6 RAM set to run at 1750 MHz through a 128-bit bus. It also is made up of 1408 Stream Processors, 88 Texture Address Units, and 32 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon R7 250X		95 Watts
Radeon RX 5500		150 Watts
	Difference: 55 Watts (58%)

Memory Bandwidth

In theory, the Radeon RX 5500 should perform much faster than the Radeon R7 250X in general. (explain)

Radeon RX 5500		229376 MB/sec
Radeon R7 250X		72000 MB/sec
	Difference: 157376 (219%)

Texel Rate

The Radeon RX 5500 will be much (more or less 267%) more effective at 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 screen resolution is important to you, then the Radeon RX 5500 is superior to the Radeon R7 250X, 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: Memory bandwidth is the max amount of information (counted in MB per second) that can be transported across the external memory interface within a second. The number is worked out by multiplying the bus width by its memory speed. If it uses DDR memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the 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 texture map elements (texels) that are applied per second. This figure is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The better this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly write to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
