Radeon R9 M370X vs Radeon RX 550

Intro

Compare all that to the Radeon RX 550, which features a clock frequency of 1100 MHz and a GDDR5 memory frequency of 1750 MHz. It also makes use of a 128-bit memory bus, and makes use of a 14 nm design. It is comprised of 512 SPUs, 32 TAUs, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon RX 550 should perform much faster than the Radeon R9 M370X overall. (explain)

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

Texel Rate

The Radeon RX 550 should be a bit (about 10%) more effective at 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 should be much (approximately 38%) faster with regards to FSAA than the Radeon R9 M370X, and also should be able to handle higher resolutions without slowing down too much. (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 largest amount of information (counted in megabytes per second) that can be moved over the external memory interface within a second. The number is worked out by multiplying the interface width by the speed of its memory. If it uses DDR RAM, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

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