Radeon HD 3470 512MB vs Radeon HD 6450 (OEM) 1GB
Intro
The Radeon HD 3470 512MB comes with a core clock speed of 800 MHz and a GDDR3 memory speed of 950 MHz. It also makes use of a 128-bit bus, and uses a 55 nm design. It is comprised of 40(8x5) SPUs, 4 TAUs, and 4 ROPs.Compare those specs to the Radeon HD 6450 (OEM) 1GB, which has GPU clock speed of 750 MHz, and 1024 MB of GDDR5 memory running at 900 MHz through a 64-bit bus. It also features 160 SPUs, 8 TAUs, and 4 ROPs.

Memory Bandwidth: Bandwidth is the largest amount of data (counted in megabytes per second) that can be transferred over the external memory interface within a second. The number is calculated by multiplying the bus width by the speed of its memory. If the card has DDR type memory, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.
Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed per second. This 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 texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.
Pixel Rate: Pixel rate is the most pixels the graphics card could possibly write to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). 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 get to the max fill rate.
