GeForce GTX 550 Ti vs Radeon R9 M365X

Intro

Compare all that to the Radeon R9 M365X, which makes use of a 28 nm design. AMD has set the core frequency at 925 MHz. The GDDR5 memory runs at a frequency of 1125 MHz on this particular card. It features 640 SPUs along with 40 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the GeForce GTX 550 Ti will be 37% quicker than the Radeon R9 M365X in general, because of its higher data rate. (explain)

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

Texel Rate

The Radeon R9 M365X should be a lot (approximately 28%) faster with regards to AF 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

The GeForce GTX 550 Ti should be a lot (about 46%) better at full screen anti-aliasing than the Radeon R9 M365X, and should be able to handle higher screen resolutions without losing too much performance. (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: Memory bandwidth is the largest amount of information (in units of MB per second) that can be moved past the external memory interface within a second. The number is worked out by multiplying the interface width by its memory clock speed. If the card has DDR memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the 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 can be applied per second. This is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The better the texel rate, 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 number of pixels that the graphics card can possibly write to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
