GeForce GTX 750 Ti vs Radeon HD 6750

Intro

Compare those specifications to the Radeon HD 6750, which features a clock speed of 725 MHz and a GDDR5 memory frequency of 1000 MHz. It also makes use of a 128-bit bus, and makes use of a 40 nm design. It is made up of 720 SPUs, 36 Texture Address Units, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 750 Ti		60 Watts
Radeon HD 6750		86 Watts
	Difference: 26 Watts (43%)

Memory Bandwidth

The GeForce GTX 750 Ti, in theory, should be a lot faster than the Radeon HD 6750 in general. (explain)

GeForce GTX 750 Ti		86400 MB/sec
Radeon HD 6750		64000 MB/sec
	Difference: 22400 (35%)

Texel Rate

The GeForce GTX 750 Ti should be quite a bit (approximately 56%) better at AF than the Radeon HD 6750. (explain)

GeForce GTX 750 Ti		40800 Mtexels/sec
Radeon HD 6750		26100 Mtexels/sec
	Difference: 14700 (56%)

Pixel Rate

If using a high screen resolution is important to you, then the GeForce GTX 750 Ti is the winner, and very much so. (explain)

GeForce GTX 750 Ti		16320 Mpixels/sec
Radeon HD 6750		11600 Mpixels/sec
	Difference: 4720 (41%)

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 maximum amount of data (in units of MB per second) that can be moved past the external memory interface in a second. It's calculated by multiplying the interface width by its memory clock speed. In the case of DDR type memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

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

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