The Radeon HD 6500M Series is aimed at the higher end of the market, for gaming or multimedia laptops. It has a processor clock speed of between 500MHz and 650MHz and a GDDR5 or DDR3 memory clock speed of 900 Mhz.
The 6500M is based on the TeraScale 2 Unified Processing architecture, which includes 400 stream processing units, 20 texture units, 32 Z/Stencil ROP nits, and 8 colour ROP units.
The Radeon HD 6300M Series is aimed at the mid-range market, still based on the TeraScale 2 architecture, but with only 80 stream processing units, 8 texture units, 16 Z/Stencil ROP units, and 4 colour ROP units.
The 6300M also only supports the DDR3 memory interface, with a memory clock speed of between 800MHz and 900MHz. The processor clock speed is between 500MHz and 750MHz.
The two series also feature AMD’s Eyefinity multi-display technology, allowing support for up to four simultaneous displays for the 6300M and six for the 6500M.
Pricing and release dates have not yet been revealed for either series.
