GeForce GTX 750 Ti vs Radeon R9 M280X

Intro

Compare those specifications to the Radeon R9 M280X, which has GPU core speed of 900 MHz, and 4096 MB of GDDR5 memory set to run at 1375 MHz through a 128-bit bus. It also is comprised of 896 Stream Processors, 56 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 750 Ti		60 Watts
Radeon R9 M280X		75 Watts
	Difference: 15 Watts (25%)

Memory Bandwidth

In theory, the Radeon R9 M280X will be 2% faster than the GeForce GTX 750 Ti in general, due to its higher data rate. (explain)

Radeon R9 M280X		88000 MB/sec
GeForce GTX 750 Ti		86400 MB/sec
	Difference: 1600 (2%)

Texel Rate

The Radeon R9 M280X will be quite a bit (approximately 24%) more effective at anisotropic filtering than the GeForce GTX 750 Ti. (explain)

Radeon R9 M280X		50400 Mtexels/sec
GeForce GTX 750 Ti		40800 Mtexels/sec
	Difference: 9600 (24%)

Pixel Rate

If using a high resolution is important to you, then the GeForce GTX 750 Ti is superior to the Radeon R9 M280X, not by a very large margin though. (explain)

GeForce GTX 750 Ti		16320 Mpixels/sec
Radeon R9 M280X		14400 Mpixels/sec
	Difference: 1920 (13%)

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 transferred past the external memory interface in a second. It's calculated by multiplying the bus width by its memory speed. In the case of DDR type memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, 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 can be applied per second. This is calculated by multiplying the total amount of texture units by the core 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 applied in one second.

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly record to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
