Radeon HD 4350 vs Radeon HD 6770
Intro
The Radeon HD 4350 features a clock speed of 575 MHz and a DDR2 memory speed of 500 MHz. It also makes use of a 64-bit memory bus, and uses a 55 nm design. It is comprised of 80(16x5) SPUs, 8 TAUs, and 4 Raster Operation Units.Compare all that to the Radeon HD 6770, which has core clock speeds of 900 MHz on the GPU, and 1050 MHz on the 512 MB of GDDR5 memory. It features 800 SPUs along with 40 TAUs and 16 ROPs.

Memory Bandwidth: Memory bandwidth is the largest amount of data (in units of megabytes per second) that can be transferred over the external memory interface in a second. It's worked out by multiplying the card's bus width by its memory speed. If it uses DDR RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the 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 amount of texture map elements (texels) that can be applied in one second. This number is calculated by multiplying the total number of texture units by the core clock speed of the chip. The better this number, 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 maximum amount of pixels that the graphics card could possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
