SAPPHIRE is introducing two new graphics families aimed
at mainstream users. The new SAPPHIRE HD 4550 has 80 stream
processors, core clock speeds of 600MHz and 512MB of GDDR3 memory clocked at
900MHz (1.8GHz effective). The SAPPHIRE HD 4350 has a similar architecture, and has the same 80 stream
processors and 600MHz core clock speed, but uses the more cost effective DDR2
memory running at 400MHz (800MHz effective). All the other features are similar
to the SAPPHIRE HD 4550.
