GeForce GTX Titan X vs Radeon HD 6750

Intro

Compare all that to the Radeon HD 6750, which features core clock speeds of 725 MHz on the GPU, and 1000 MHz on the 512 MB of GDDR5 memory. It features 720 SPUs along with 36 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

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

Memory Bandwidth

As far as performance goes, the GeForce GTX Titan X should in theory be a lot superior to the Radeon HD 6750 overall. (explain)

GeForce GTX Titan X		336000 MB/sec
Radeon HD 6750		64000 MB/sec
	Difference: 272000 (425%)

Texel Rate

The GeForce GTX Titan X is quite a bit (approximately 636%) faster with regards to texture filtering than the Radeon HD 6750. (explain)

GeForce GTX Titan X		192000 Mtexels/sec
Radeon HD 6750		26100 Mtexels/sec
	Difference: 165900 (636%)

Pixel Rate

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

GeForce GTX Titan X		96000 Mpixels/sec
Radeon HD 6750		11600 Mpixels/sec
	Difference: 84400 (728%)

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 largest amount of information (measured in megabytes per second) that can be moved over the external memory interface in one second. The number is calculated by multiplying the bus width by its memory speed. If the card has DDR type RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, 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 texture map elements (texels) that are processed in one second. This figure is calculated by multiplying the total texture units by the core clock 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 per second.

Pixel Rate: Pixel rate is the most pixels the video card could possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour ROPs 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 fill rate is also dependant on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
