GeForce GTX 550 Ti vs Radeon R9 M370X

Intro

Compare all that to the Radeon R9 M370X, which uses a 28 nm design. AMD has clocked the core frequency at 800 MHz. The GDDR5 memory is set to run at a speed of 1125 MHz on this card. It features 640 SPUs along with 40 Texture Address Units and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

As far as performance goes, the GeForce GTX 550 Ti should in theory be a lot better than the Radeon R9 M370X in general. (explain)

GeForce GTX 550 Ti		98496 MB/sec
Radeon R9 M370X		72000 MB/sec
	Difference: 26496 (37%)

Texel Rate

The Radeon R9 M370X will be a little bit (more or less 11%) faster with regards to anisotropic filtering than the GeForce GTX 550 Ti. (explain)

Radeon R9 M370X		32000 Mtexels/sec
GeForce GTX 550 Ti		28800 Mtexels/sec
	Difference: 3200 (11%)

Pixel Rate

The GeForce GTX 550 Ti is a lot (approximately 69%) more effective at anti-aliasing than the Radeon R9 M370X, and capable of handling higher screen resolutions without slowing down too much. (explain)

GeForce GTX 550 Ti		21600 Mpixels/sec
Radeon R9 M370X		12800 Mpixels/sec
	Difference: 8800 (69%)

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 megabytes per second) that can be transferred across the external memory interface in a second. It is worked out by multiplying the card's interface width by its memory speed. If it uses DDR type RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. 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 amount of texture map elements (texels) that can be applied in one second. This figure is worked out by multiplying the total texture units by the core speed of the chip. The higher this number, the better the graphics 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 can possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of ROPs 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 rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
