GeForce GTX Titan Black vs Radeon HD 6750

Intro

Compare those specifications to the Radeon HD 6750, which has a core clock speed of 725 MHz and a GDDR5 memory frequency of 1000 MHz. It also uses a 128-bit bus, and makes use of a 40 nm design. It is comprised of 720 SPUs, 36 TAUs, and 16 ROPs.

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

Pixel Rate

The GeForce GTX Titan Black will be quite a bit (about 268%) better at FSAA than the Radeon HD 6750, and also capable of handling higher screen resolutions while still performing well. (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: Bandwidth is the largest amount of information (measured in MB per second) that can be transported across the external memory interface within a second. It is worked out by multiplying the card's interface width by the speed of its memory. In the case of DDR type RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly record to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
