Radeon HD 4670 1GB vs Radeon HD 6570 (OEM) 1GB
Intro
The Radeon HD 4670 1GB makes use of a 55 nm design. AMD has clocked the core speed at 750 MHz. The GDDR4/GDDR3/DDR3/DDR2 memory works at a speed of 1100 MHz on this card. It features 320(64x5) SPUs as well as 32 Texture Address Units and 8 ROPs.Compare all that to the Radeon HD 6570 (OEM) 1GB, which uses a 40 nm design. AMD has clocked the core frequency at 650 MHz. The GDDR3 RAM is set to run at a frequency of 900 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 max amount of data (in units of MB per second) that can be transferred over the external memory interface in a second. It is calculated by multiplying the card's interface width by its memory clock speed. If it uses DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed per second. This figure is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The better this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.
Pixel Rate: Pixel rate is the most pixels the graphics card could possibly write to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Render Output Units by the the core 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 also depends on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
