GeForce GTX Titan X vs Radeon R9 280X

Intro

The GeForce GTX Titan X features a clock speed of 1000 MHz and a GDDR5 memory speed of 1750 MHz. It also makes use of a 384-bit bus, and uses a 28 nm design. It is made up of 3072 SPUs, 192 TAUs, and 96 ROPs.

Compare all of that to the Radeon R9 280X, which features a core clock frequency of 850 MHz and a GDDR5 memory frequency of 1500 MHz. It also features a 384-bit memory bus, and makes use of a 28 nm design. It is made up of 2048 SPUs, 128 Texture Address Units, and 32 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

In theory, the GeForce GTX Titan X is 17% quicker than the Radeon R9 280X overall, due to its greater bandwidth. (explain)

GeForce GTX Titan X 336000 MB/sec
Radeon R9 280X 288000 MB/sec
Difference: 48000 (17%)

Texel Rate

The GeForce GTX Titan X should be quite a bit (more or less 76%) more effective at anisotropic filtering than the Radeon R9 280X. (explain)

GeForce GTX Titan X 192000 Mtexels/sec
Radeon R9 280X 108800 Mtexels/sec
Difference: 83200 (76%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GTX Titan X is the winner, and very much so. (explain)

GeForce GTX Titan X 96000 Mpixels/sec
Radeon R9 280X 27200 Mpixels/sec
Difference: 68800 (253%)

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.

Memory Bandwidth: Bandwidth is the largest amount of data (in units of megabytes per second) that can be transported across the external memory interface within a second. The number is calculated by multiplying the interface width by the speed of its memory. If it uses DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed in one second. This figure is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The better 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 a second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly write to its 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 clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as 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 memory bandwidth is, the lower the ability to get to the maximum fill rate.
