Radeon HD 5450 vs Radeon HD 5670
Intro
The Radeon HD 5450 makes use of a 40 nm design. AMD has clocked the core speed at 650 MHz. The DDR3 memory works at a frequency of 800 MHz on this card. It features 80(16x5) SPUs along with 8 TAUs and 4 ROPs.Compare those specs to the Radeon HD 5670, which uses a 40 nm design. AMD has clocked the core speed at 775 MHz. The GDDR5 RAM works at a frequency of 1000 MHz on this card. It features 400(80x5) SPUs as well as 20 TAUs and 8 ROPs.

Memory Bandwidth: Memory bandwidth is the maximum amount of data (counted in MB per second) that can be transferred over the external memory interface in a second. It is worked out by multiplying the interface width by its memory speed. In the case of DDR type RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed per second. This figure is calculated by multiplying the total amount of texture units by the core clock 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 applied in a second.
Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka 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 - the lower the bandwidth is, the lower the ability to get to the max fill rate.
