Radeon HD 4350 vs Radeon HD 6450 (OEM)
Intro
The Radeon HD 4350 features a clock frequency of 575 MHz and a DDR2 memory speed of 500 MHz. It also makes use of a 64-bit memory bus, and makes use of a 55 nm design. It features 80(16x5) SPUs, 8 TAUs, and 4 Raster Operation Units.Compare those specifications to the Radeon HD 6450 (OEM), which makes use of a 40 nm design. AMD has clocked the core frequency at 625 MHz. The GDDR3 memory works at a frequency of 800 MHz on this model. It features 160 SPUs as well as 8 TAUs and 4 Rasterization Operator Units.

Memory Bandwidth: Memory bandwidth is the max amount of information (measured in MB per second) that can be moved past the external memory interface in one second. It's calculated by multiplying the card's interface width by the speed of its memory. If the card has DDR RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied per second. This figure is worked out by multiplying the total number of texture units by the core speed of the chip. The higher the texel rate, 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 maximum number of pixels the graphics card could possibly write to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output 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 ability to reach the max fill rate.
