GeForce GTX 550 Ti vs Radeon R9 M295X

Intro

Compare those specs to the Radeon R9 M295X, which makes use of a 28 nm design. AMD has clocked the core frequency at 750 MHz. The GDDR5 memory works at a frequency of 1375 MHz on this model. It features 2048 SPUs along with 128 TAUs and 32 ROPs.

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

Theoretically speaking, the Radeon R9 M295X should be 79% faster than the GeForce GTX 550 Ti in general, because of its greater data rate. (explain)

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

Texel Rate

The Radeon R9 M295X will be a lot (approximately 233%) more effective at texture 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 is just a bit (about 11%) more effective at full screen anti-aliasing than the GeForce GTX 550 Ti, and should be capable of handling higher screen resolutions better. (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: Memory bandwidth is the maximum amount of data (measured in MB per second) that can be transported over the external memory interface in a second. It is worked out by multiplying the card's bus width by its memory speed. If it uses DDR RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of 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 number of Render Output Units by the clock speed of the card. 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 many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
