Nvidia Titan X vs Radeon R9 280

Intro

Compare that to the Radeon R9 280, which features core speeds of 933 MHz on the GPU, and 1250 MHz on the 3072 MB of GDDR5 memory. It features 1792 SPUs along with 112 TAUs and 32 ROPs.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

In theory, the Nvidia Titan X should perform quite a bit faster than the Radeon R9 280 in general. (explain)

Nvidia Titan X		491520 MB/sec
Radeon R9 280		240000 MB/sec
	Difference: 251520 (105%)

Texel Rate

The Nvidia Titan X is quite a bit (approximately 204%) more effective at anisotropic filtering than the Radeon R9 280. (explain)

Nvidia Titan X		317408 Mtexels/sec
Radeon R9 280		104496 Mtexels/sec
	Difference: 212912 (204%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Nvidia Titan X is the winner, by a large margin. (explain)

Nvidia Titan X		136032 Mpixels/sec
Radeon R9 280		29856 Mpixels/sec
	Difference: 106176 (356%)

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 transported past the external memory interface in a second. It's calculated by multiplying the card's interface width by the speed of its memory. If the card has DDR memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed in one second. This figure is worked out by multiplying the total texture units by the core speed of the chip. The better this number, the better the graphics card will be at 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 card can possibly record to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
