GeForce GTX 550 Ti vs Radeon R9 M365X

Intro

Compare that to the Radeon R9 M365X, which comes with GPU core speed of 925 MHz, and 4096 MB of GDDR5 memory set to run at 1125 MHz through a 128-bit bus. It also is made up of 640 SPUs, 40 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The GeForce GTX 550 Ti should theoretically perform much faster than the Radeon R9 M365X in general. (explain)

GeForce GTX 550 Ti		98496 MB/sec
Radeon R9 M365X		72000 MB/sec
	Difference: 26496 (37%)

Texel Rate

The Radeon R9 M365X is a lot (about 28%) more effective at anisotropic filtering than the GeForce GTX 550 Ti. (explain)

Radeon R9 M365X		37000 Mtexels/sec
GeForce GTX 550 Ti		28800 Mtexels/sec
	Difference: 8200 (28%)

Pixel Rate

If using a high screen resolution is important to you, then the GeForce GTX 550 Ti is a better choice, and very much so. (explain)

GeForce GTX 550 Ti		21600 Mpixels/sec
Radeon R9 M365X		14800 Mpixels/sec
	Difference: 6800 (46%)

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 max amount of data (in units of megabytes per second) that can be transferred over the external memory interface in a second. It is calculated by multiplying the card's bus width by its memory clock speed. In the case of DDR RAM, it must be multiplied by 2 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 number of texture map elements (texels) that are applied in one second. This number is calculated by multiplying the total amount of texture units of the card by the core clock 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 in one second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of ROPs by the the core speed of the card. 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 rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
