Radeon R7 M265 vs Radeon RX 550

Intro

Compare all that to the Radeon RX 550, which has a GPU core 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 SPUs, 32 Texture Address Units, and 16 Raster Operation Units.

Radeon R7 M265		17400 Mtexels/sec
	Difference: 17800 (102%)

Pixel Rate

The Radeon RX 550 should be quite a bit (approximately 203%) more effective at full screen anti-aliasing than the Radeon R7 M265, and also capable of handling higher resolutions without slowing down too much. (explain)

Radeon RX 550		17600 Mpixels/sec
Radeon R7 M265		5800 Mpixels/sec
	Difference: 11800 (203%)

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: Bandwidth is the largest amount of data (in units of MB per second) that can be transported over the external memory interface in one second. It is calculated by multiplying the interface width by its memory clock speed. In the case of DDR memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, 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 amount of texture map elements (texels) that are processed in one second. This figure is calculated by multiplying the total texture units of the card by the core speed of the chip. The higher the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly record to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
