Radeon HD 3470 256MB vs Radeon HD 6450 (OEM)
Intro
The Radeon HD 3470 256MB makes use of a 55 nm design. AMD has clocked the core frequency at 800 MHz. The DDR2 memory works at a speed of 950 MHz on this specific model. It features 40(8x5) SPUs along with 4 TAUs and 4 Rasterization Operator Units.Compare all of that to the Radeon HD 6450 (OEM), which features GPU core speed of 625 MHz, and 512 MB of GDDR3 memory running at 800 MHz through a 64-bit bus. It also features 160 SPUs, 8 TAUs, and 4 Raster Operation Units.

Memory Bandwidth: Bandwidth is the largest amount of information (measured in megabytes per second) that can be transferred over the external memory interface within a second. The number is worked out by multiplying the card's interface width by its memory clock speed. If it uses DDR type memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the better 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 number of texture map elements (texels) that are applied per second. This number is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.
Pixel Rate: Pixel rate is the most pixels the video card could possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Render Output Units 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 fill rate is also dependant on quite a few 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.
