Sapphire has a new high-end graphics accelerator in the works for launch next week: the Atomic HD 4890. The card features a blue reference PCB by AMD with a few enhancements, paired with Sapphire's Vapor-X cooler to keep this factory-overclocked card cool, and more importantly, quieter than the reference cooler.

What makes this card even more special is that Sapphire generously overclocked it. The core runs at 1000 MHz, and the 1 GB of GDDR5 memory at 1050 MHz (2100 MHz DDR, 4200 MHz effective). The Catalyst Control Center ATI Overdrive page shows its GPU core overlocking limit upped to 1100 MHz, from the 1000 MHz limit release-drivers were noted to come with. To sustain such high speeds, the card's VRM has been slightly expanded. The card uses an 8-pin PCI-E power connector alongside a 6-pin one. The price of this card is yet to be known.
