Nvidia Titan X vs Radeon R9 270X

Intro

Compare all that to the Radeon R9 270X, which makes use of a 28 nm design. AMD has set the core frequency at 1000 MHz. The GDDR5 RAM works at a frequency of 1400 MHz on this particular card. It features 1280 SPUs along with 80 TAUs and 32 ROPs.

Radeon R9 270X		179200 MB/sec
	Difference: 312320 (174%)

Texel Rate

The Nvidia Titan X will be quite a bit (approximately 297%) more effective at anisotropic filtering than the Radeon R9 270X. (explain)

Nvidia Titan X		317408 Mtexels/sec
Radeon R9 270X		80000 Mtexels/sec
	Difference: 237408 (297%)

Pixel Rate

If running with high levels of AA is important to you, then the Nvidia Titan X is a better choice, by far. (explain)

Nvidia Titan X		136032 Mpixels/sec
Radeon R9 270X		32000 Mpixels/sec
	Difference: 104032 (325%)

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 data (counted in MB per second) that can be transferred over the external memory interface in a second. The number is worked out by multiplying the bus width by its memory clock speed. If it uses DDR RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's 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 amount of texture map elements (texels) that can be processed per second. This figure is worked out by multiplying the total texture units of the card by the core speed of the chip. The better the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the most pixels the video card could possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - aka 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 potential to reach the max fill rate.
