GeForce GTX 550 Ti vs Radeon R9 M295X

Intro

Compare all of that to the Radeon R9 M295X, which uses a 28 nm design. AMD has clocked the core frequency at 750 MHz. The GDDR5 RAM runs at a frequency of 1375 MHz on this card. It features 2048 SPUs along with 128 TAUs and 32 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 550 Ti		116 Watts
Radeon R9 M295X		125 Watts
	Difference: 9 Watts (8%)

Memory Bandwidth

As far as performance goes, the Radeon R9 M295X should theoretically be quite a bit better than the GeForce GTX 550 Ti in general. (explain)

Radeon R9 M295X		176000 MB/sec
GeForce GTX 550 Ti		98496 MB/sec
	Difference: 77504 (79%)

Texel Rate

The Radeon R9 M295X should be much (about 233%) better at anisotropic filtering than the GeForce GTX 550 Ti. (explain)

Radeon R9 M295X		96000 Mtexels/sec
GeForce GTX 550 Ti		28800 Mtexels/sec
	Difference: 67200 (233%)

Pixel Rate

The Radeon R9 M295X will be a bit (more or less 11%) more effective at full screen anti-aliasing than the GeForce GTX 550 Ti, and should be able to handle higher resolutions without losing too much performance. (explain)

Radeon R9 M295X		24000 Mpixels/sec
GeForce GTX 550 Ti		21600 Mpixels/sec
	Difference: 2400 (11%)

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 information (counted in MB per second) that can be moved over the external memory interface in a second. It's calculated by multiplying the card's bus width by its memory clock speed. In the case of DDR type 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 AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly record to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount 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 is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
