Nvidia Titan X vs Radeon R9 270

Intro

Compare all of that to the Radeon R9 270, which has a clock frequency of 900 MHz and a GDDR5 memory frequency of 1400 MHz. It also uses a 256-bit bus, and makes use of a 28 nm design. It is made up of 1280 SPUs, 80 TAUs, and 32 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon R9 270		150 Watts
Nvidia Titan X		250 Watts
	Difference: 100 Watts (67%)

Memory Bandwidth

In theory, the Nvidia Titan X should perform quite a bit faster than the Radeon R9 270 in general. (explain)

Nvidia Titan X		491520 MB/sec
Radeon R9 270		179200 MB/sec
	Difference: 312320 (174%)

Texel Rate

The Nvidia Titan X should be much (more or less 341%) faster with regards to anisotropic filtering than the Radeon R9 270. (explain)

Nvidia Titan X		317408 Mtexels/sec
Radeon R9 270		72000 Mtexels/sec
	Difference: 245408 (341%)

Pixel Rate

If running with a high resolution is important to you, then the Nvidia Titan X is a better choice, and very much so. (explain)

Nvidia Titan X		136032 Mpixels/sec
Radeon R9 270		28800 Mpixels/sec
	Difference: 107232 (372%)

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 information (in units of MB per second) that can be transferred past the external memory interface in a second. The number is worked out by multiplying the card's bus width by its memory clock speed. In the case of DDR RAM, 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 anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed per second. This is calculated by multiplying the total amount of texture units of the card 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 processed per second.

Pixel Rate: Pixel rate is the most pixels the video card can 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 Raster Operations Pipelines by the the core 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 many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
