We’ve discussed the Sapphire Atomic HD 4890 before, but a little bit of new information has come to light:

Packed in an exclusive Atomic aluminum case, the card features 1GB GDDR5 and core/memory clock of 1000/1050MHz (effective 4200MHz). The other features keep unchanged: 800 stream processors, 256-bit memory interface and support for ATI CrossFireX.

Sapphire is expected to officially announce the card tomorrow.
