GeForce GTX 780 Ti vs Radeon R9 M375X

Intro

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

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the GeForce GTX 780 Ti should be much faster than the Radeon R9 M375X overall. (explain)

GeForce GTX 780 Ti		336000 MB/sec
Radeon R9 M375X		72000 MB/sec
	Difference: 264000 (367%)

Texel Rate

The GeForce GTX 780 Ti will be much (about 417%) more effective at AF than the Radeon R9 M375X. (explain)

GeForce GTX 780 Ti		210000 Mtexels/sec
Radeon R9 M375X		40600 Mtexels/sec
	Difference: 169400 (417%)

Pixel Rate

If using high levels of AA is important to you, then the GeForce GTX 780 Ti is a better choice, by far. (explain)

GeForce GTX 780 Ti		42000 Mpixels/sec
Radeon R9 M375X		16240 Mpixels/sec
	Difference: 25760 (159%)

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 max amount of data (measured in megabytes per second) that can be transferred across the external memory interface within a second. It's calculated by multiplying the bus width by its memory clock speed. If it uses DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied per second. This figure is calculated by multiplying the total number of 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 maximum number of pixels that the graphics chip can possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
