Radeon R9 M270X vs Radeon RX 550

Intro

Compare all of that to the Radeon RX 550, which comes with GPU clock speed of 1100 MHz, and 2048 MB of GDDR5 memory set to run at 1750 MHz through a 128-bit bus. It also is comprised of 512 Stream Processors, 32 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

As far as performance goes, the Radeon RX 550 should in theory be a lot superior to the Radeon R9 M270X overall. (explain)

Radeon RX 550		114688 MB/sec
Radeon R9 M270X		72000 MB/sec
	Difference: 42688 (59%)

Texel Rate

The Radeon RX 550 is a lot (more or less 21%) more effective at AF than the Radeon R9 M270X. (explain)

Radeon RX 550		35200 Mtexels/sec
Radeon R9 M270X		29000 Mtexels/sec
	Difference: 6200 (21%)

Pixel Rate

The Radeon RX 550 should be much (more or less 52%) faster with regards to AA than the Radeon R9 M270X, and also will be able to handle higher screen resolutions while still performing well. (explain)

Radeon RX 550		17600 Mpixels/sec
Radeon R9 M270X		11600 Mpixels/sec
	Difference: 6000 (52%)

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 (in units of megabytes per second) that can be transferred past the external memory interface in a second. It is calculated by multiplying the card's interface width by the speed of its memory. In the case of DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster 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 processed in one second. This number is calculated by multiplying the total texture units by the core clock speed of the chip. The higher this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly record to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of ROPs 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 is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
