Radeon HD 4670 1GB vs Radeon HD 6570 (OEM) 1GB
Intro
The Radeon HD 4670 1GB comes with a GPU core speed of 750 MHz, and the 1024 MB of GDDR4/GDDR3/DDR3/DDR2 RAM is set to run at 1100 MHz through a 128-bit bus. It also is comprised of 320(64x5) Stream Processors, 32 Texture Address Units, and 8 Raster Operation Units.Compare those specs to the Radeon HD 6570 (OEM) 1GB, which has a clock frequency of 650 MHz and a GDDR3 memory speed of 900 MHz. It also makes use of a 128-bit memory bus, and uses a 40 nm design. It is comprised of 480 SPUs, 24 Texture Address Units, and 8 ROPs.

Memory Bandwidth: Bandwidth is the maximum amount of data (counted in megabytes per second) that can be moved past the external memory interface within a second. It's worked out by multiplying the interface width by its memory speed. If it uses DDR RAM, it must 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 anti-aliasing, 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 calculated by multiplying the total amount of texture units by the core clock speed of the chip. The higher this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per 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 amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
