Nvidia Titan X vs Radeon R9 280X

Intro

The Nvidia Titan X features a clock frequency of 1417 MHz and a GDDR5X memory frequency of 1251 MHz. It also features a 384-bit memory bus, and makes use of a 16 nm design. It features 3584 SPUs, 224 TAUs, and 96 Raster Operation Units.

Compare those specs to the Radeon R9 280X, which features GPU core speed of 850 MHz, and 3072 MB of GDDR5 RAM running at 1500 MHz through a 384-bit bus. It also is made up of 2048 SPUs, 128 Texture Address Units, and 32 ROPs.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

The Nvidia Titan X, in theory, should perform much faster than the Radeon R9 280X overall. (explain)

Nvidia Titan X 491520 MB/sec
Radeon R9 280X 288000 MB/sec
Difference: 203520 (71%)

Texel Rate

The Nvidia Titan X should be quite a bit (approximately 192%) faster with regards to texture filtering than the Radeon R9 280X. (explain)

Nvidia Titan X 317408 Mtexels/sec
Radeon R9 280X 108800 Mtexels/sec
Difference: 208608 (192%)

Pixel Rate

The Nvidia Titan X will be a lot (about 400%) better at AA than the Radeon R9 280X, and capable of handling higher resolutions more effectively. (explain)

Nvidia Titan X 136032 Mpixels/sec
Radeon R9 280X 27200 Mpixels/sec
Difference: 108832 (400%)

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 information (measured in megabytes per second) that can be moved over the external memory interface within a second. It's calculated by multiplying the bus width by its memory speed. If the card has DDR type RAM, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better 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 number of texture map elements (texels) that are processed per second. This number is calculated by multiplying the total number of texture units by the core speed of the chip. The better this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels 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 figure is calculated by multiplying the amount of ROPs by the the card's clock speed. 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 fill rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
