Nvidia Titan X vs Radeon HD 6750

Intro

Compare that to the Radeon HD 6750, which uses a 40 nm design. AMD has clocked the core frequency at 725 MHz. The GDDR5 memory is set to run at a frequency of 1000 MHz on this particular model. It features 720 SPUs along with 36 TAUs and 16 ROPs.

Power Consumption (Max TDP)

Radeon HD 6750		86 Watts
Nvidia Titan X		250 Watts
	Difference: 164 Watts (191%)

Memory Bandwidth

The Nvidia Titan X, in theory, should perform quite a bit faster than the Radeon HD 6750 overall. (explain)

Nvidia Titan X		491520 MB/sec
Radeon HD 6750		64000 MB/sec
	Difference: 427520 (668%)

Texel Rate

The Nvidia Titan X will be much (about 1116%) more effective at AF than the Radeon HD 6750. (explain)

Nvidia Titan X		317408 Mtexels/sec
Radeon HD 6750		26100 Mtexels/sec
	Difference: 291308 (1116%)

Pixel Rate

If using a high resolution is important to you, then the Nvidia Titan X is the winner, by a large margin. (explain)

Nvidia Titan X		136032 Mpixels/sec
Radeon HD 6750		11600 Mpixels/sec
	Difference: 124432 (1073%)

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: Bandwidth is the maximum amount of data (counted in megabytes per second) that can be transferred across the external memory interface in a second. It's worked out by multiplying the interface width by its memory clock speed. If it uses DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied in one second. This number is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher this number, 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 maximum number of pixels the video card could possibly record to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
