Radeon HD 3470 256MB vs Radeon HD 6570 (OEM) 2GB
Intro
The Radeon HD 3470 256MB uses a 55 nm design. AMD has clocked the core speed at 800 MHz. The DDR2 RAM works at a speed of 950 MHz on this specific model. It features 40(8x5) SPUs as well as 4 Texture Address Units and 4 Rasterization Operator Units.Compare those specs to the Radeon HD 6570 (OEM) 2GB, which makes use of a 40 nm design. AMD has clocked the core frequency at 650 MHz. The GDDR5 RAM is set to run at a speed of 1000 MHz on this particular card. It features 480 SPUs along with 24 Texture Address Units and 8 Rasterization Operator Units.

Memory Bandwidth: Bandwidth is the largest amount of data (measured in MB per second) that can be transported across the external memory interface in one second. It is worked out by multiplying the card's interface width by the speed of its memory. In the case of DDR memory, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed in one second. This number is worked out by multiplying the total number of texture units by the core clock speed of the chip. The higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.
Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly record to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of Raster Operations Pipelines 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 rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
