Radeon HD 5750 512MB vs Radeon HD 6750 1GB
Intro
The Radeon HD 5750 512MB makes use of a 40 nm design. AMD has clocked the core frequency at 700 MHz. The GDDR5 RAM is set to run at a speed of 1150 MHz on this particular card. It features 720(144x5) SPUs as well as 36 Texture Address Units and 16 Rasterization Operator Units.Compare all of that to the Radeon HD 6750 1GB, which features a clock speed of 725 MHz and a GDDR5 memory speed of 1000 MHz. It also features a 128-bit memory bus, and uses a 40 nm design. It features 720 SPUs, 36 Texture Address Units, and 16 Raster Operation Units.
Power Usage and Theoretical Benchmarks
Both cards have the same power consumption.Memory Bandwidth
The Radeon HD 5750 512MB, in theory, should be a bit faster than the Radeon HD 6750 1GB in general. (explain)

Memory Bandwidth: Bandwidth is the largest amount of data (measured in megabytes per second) that can be transported across the external memory interface in a second. It's calculated by multiplying the bus width by its memory speed. If the card has DDR RAM, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied per second. This number is calculated by multiplying the total amount of texture units by the core speed of the chip. The higher this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.
Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly record to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
