GeForce GTX 750 Ti vs Radeon R9 M375X

Intro

Compare those specs to the Radeon R9 M375X, which features a GPU core clock speed of 1015 MHz, and 4096 MB of GDDR5 RAM set to run at 1125 MHz through a 128-bit bus. It also is made up of 640 Stream Processors, 40 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the GeForce GTX 750 Ti should be 20% quicker than the Radeon R9 M375X overall, because of its greater data rate. (explain)

GeForce GTX 750 Ti		86400 MB/sec
Radeon R9 M375X		72000 MB/sec
	Difference: 14400 (20%)

Texel Rate

The GeForce GTX 750 Ti is a little bit (approximately 0%) more effective at texture filtering than the Radeon R9 M375X. (explain)

GeForce GTX 750 Ti		40800 Mtexels/sec
Radeon R9 M375X		40600 Mtexels/sec
	Difference: 200 (0%)

Pixel Rate

The GeForce GTX 750 Ti should be a small bit (more or less 0%) more effective at full screen anti-aliasing than the Radeon R9 M375X, and able to handle higher screen resolutions better. (explain)

GeForce GTX 750 Ti		16320 Mpixels/sec
Radeon R9 M375X		16240 Mpixels/sec
	Difference: 80 (0%)

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 (counted in MB per second) that can be transferred over the external memory interface within a second. It's worked out by multiplying the card's interface width by its memory clock speed. In the case of DDR type RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied per second. This number is calculated by multiplying the total number of texture units by the core speed of the chip. The higher the texel rate, the better the video 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 chip can possibly record to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
