Radeon R9 M265X vs Radeon RX 550

Intro

Compare those specs to the Radeon RX 550, which comes with core speeds of 1100 MHz on the GPU, and 1750 MHz on the 2048 MB of GDDR5 memory. It features 512 SPUs along with 32 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Performance-wise, the Radeon RX 550 should theoretically be a lot better than the Radeon R9 M265X in general. (explain)

Radeon RX 550		114688 MB/sec
Radeon R9 M265X		72000 MB/sec
	Difference: 42688 (59%)

Texel Rate

The Radeon RX 550 is a lot (approximately 53%) faster with regards to anisotropic filtering than the Radeon R9 M265X. (explain)

Radeon RX 550		35200 Mtexels/sec
Radeon R9 M265X		23000 Mtexels/sec
	Difference: 12200 (53%)

Pixel Rate

The Radeon RX 550 is quite a bit (approximately 91%) more effective at anti-aliasing than the Radeon R9 M265X, and also should be able to handle higher screen resolutions without slowing down too much. (explain)

Radeon RX 550		17600 Mpixels/sec
Radeon R9 M265X		9200 Mpixels/sec
	Difference: 8400 (91%)

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.

Price Comparison

Specifications

Memory Bandwidth: Bandwidth is the maximum amount of data (in units of MB per second) that can be transported across the external memory interface in a second. It is calculated by multiplying the card's bus width by the speed of its memory. If it uses DDR memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied per second. This number is calculated by multiplying the total texture units by the core clock speed of the chip. The higher the texel rate, the better the graphics card will be at 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 chip could possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Raster Operations Pipelines by the the card's 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 fill rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
