Radeon R9 M370X vs Radeon RX 550

Intro

Compare those specifications to the Radeon RX 550, which uses a 14 nm design. AMD has clocked the core speed at 1100 MHz. The GDDR5 memory runs at a frequency of 1750 MHz on this particular model. It features 512 SPUs as well as 32 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon RX 550 should be 59% faster than the Radeon R9 M370X overall, because of its higher data rate. (explain)

Radeon RX 550		114688 MB/sec
Radeon R9 M370X		72000 MB/sec
	Difference: 42688 (59%)

Texel Rate

The Radeon RX 550 should be just a bit (more or less 10%) faster with regards to anisotropic filtering than the Radeon R9 M370X. (explain)

Radeon RX 550		35200 Mtexels/sec
Radeon R9 M370X		32000 Mtexels/sec
	Difference: 3200 (10%)

Pixel Rate

The Radeon RX 550 is a lot (more or less 38%) faster with regards to FSAA than the Radeon R9 M370X, and also able to handle higher screen resolutions without losing too much performance. (explain)

Radeon RX 550		17600 Mpixels/sec
Radeon R9 M370X		12800 Mpixels/sec
	Difference: 4800 (38%)

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

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied per second. This figure is worked out by multiplying the total number of texture units of the card by the core clock 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 that the graphics card could possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
