Nvidia Titan X vs Radeon R9 280X

Intro

Compare those specs to the Radeon R9 280X, which uses a 28 nm design. AMD has set the core frequency at 850 MHz. The GDDR5 memory works at a frequency of 1500 MHz on this specific model. It features 2048 SPUs along with 128 TAUs and 32 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

As far as performance goes, the Nvidia Titan X should in theory be quite a bit better than the Radeon R9 280X in general. (explain)

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

Texel Rate

The Nvidia Titan X should be much (about 192%) more effective at anisotropic 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 should be quite a bit (approximately 400%) faster with regards to AA than the Radeon R9 280X, and should be capable of handling higher screen resolutions better. (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.

Specifications

Memory Bandwidth: Memory bandwidth is the maximum amount of information (in units of megabytes per second) that can be moved over the external memory interface in a second. It is worked out by multiplying the interface width by its memory clock speed. In the case of DDR type memory, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed in one second. This is calculated by multiplying the total amount of texture units by the core speed of the chip. The better the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on quite a few 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.
