GeForce GTX Titan Black vs Radeon R9 M280X

Intro

Compare all that to the Radeon R9 M280X, which uses a 28 nm design. AMD has set the core frequency at 900 MHz. The GDDR5 memory runs at a speed of 1375 MHz on this card. It features 896 SPUs along with 56 Texture Address Units and 16 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon R9 M280X		75 Watts
GeForce GTX Titan Black		250 Watts
	Difference: 175 Watts (233%)

Memory Bandwidth

The GeForce GTX Titan Black should in theory perform a lot faster than the Radeon R9 M280X in general. (explain)

GeForce GTX Titan Black		336000 MB/sec
Radeon R9 M280X		88000 MB/sec
	Difference: 248000 (282%)

Texel Rate

The GeForce GTX Titan Black will be quite a bit (more or less 323%) faster with regards to anisotropic filtering than the Radeon R9 M280X. (explain)

GeForce GTX Titan Black		213360 Mtexels/sec
Radeon R9 M280X		50400 Mtexels/sec
	Difference: 162960 (323%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce GTX Titan Black is a better choice, by far. (explain)

GeForce GTX Titan Black		42672 Mpixels/sec
Radeon R9 M280X		14400 Mpixels/sec
	Difference: 28272 (196%)

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 largest amount of data (in units of megabytes per second) that can be moved past the external memory interface within a second. The number is calculated by multiplying the card's bus width by its memory clock speed. If the card has DDR type memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed in one second. This number is worked out 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 texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly record to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called 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, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
