byGuru3d
'We've seen a couple of cards announced already, but AMD officially launched their 1 GHz clock SKU of the Radeon HD 4890.
They’ve announced this new version of their ATI Radeon HD 4890 graphics chipset that will be factory-overclocked to bump up the standard speed from 850MHz to 1GHz.
It's a milestone really as this is actually the first graphics processor to reach the 1GHz mark, so congratz are due to AMD! Plus, this boost actually increases the computing power to 1.6 teraflops from the previous 1.36 teraflops.'
