GeForce GTX Titan Black vs Radeon HD 6750

Intro

Compare all of that to the Radeon HD 6750, which uses a 40 nm design. AMD has set the core speed at 725 MHz. The GDDR5 memory runs at a speed of 1000 MHz on this model. It features 720 SPUs as well as 36 Texture Address Units and 16 ROPs.

Radeon HD 6750		26100 Mtexels/sec
	Difference: 187260 (717%)

Pixel Rate

The GeForce GTX Titan Black is a lot (more or less 268%) faster with regards to anti-aliasing than the Radeon HD 6750, and also will be able to handle higher screen resolutions without losing too much performance. (explain)

GeForce GTX Titan Black		42672 Mpixels/sec
Radeon HD 6750		11600 Mpixels/sec
	Difference: 31072 (268%)

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 within a second. It is worked out by multiplying the interface width by its memory speed. If the card has DDR type memory, it must be multiplied by 2 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, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly write to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
