GeForce GTX 750 vs Radeon HD 6950 2GB
Intro
The GeForce GTX 750 comes with a clock frequency of 1020 MHz and a GDDR5 memory frequency of 1250 MHz. It also uses a 128-bit memory bus, and uses a 28 nm design. It features 512 SPUs, 32 Texture Address Units, and 16 Raster Operation Units.Compare that to the Radeon HD 6950 2GB, which uses a 40 nm design. AMD has clocked the core speed at 800 MHz. The GDDR5 memory works at a speed of 1250 MHz on this particular model. It features 1408 SPUs along with 88 Texture Address Units and 32 ROPs.

Memory Bandwidth: Bandwidth is the largest amount of information (counted in megabytes per second) that can be transferred across the external memory interface in one second. It is calculated by multiplying the bus width by its memory clock speed. In the case of DDR RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's 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 are applied per second. This number is worked out by multiplying the total texture units by the core 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 per second.
Pixel Rate: Pixel rate is the most pixels the graphics card can possibly record to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
