Despite the experience, that the HD 4890 is not officially in the market yet and will not be there until April 2, rumour already has it about first overclocked versions.
And indeed there are many reports by now that lead to a nearly sure conclusion that the HD 4890 has a good frequency potential against former ATI performance- and high end cards, and so are the AIB partner are to present faster cards.

techPowerUp! did more or less bring up these rumours, they reported about a planned Asus model with 900 MHz chip frequency and 1000 MHz memory frequency on the beginning of next week. End of last week, ATI-Forum followed with a indication of an also overclocked Sapphire HD 4890. Here also 900 MHz chip frequency were mentioned.

And when the first listings appeared in online shops, you came aware of a HIS card with 900 MHz chip frequency and 1000 MHz memory frequency. Today, the hint on a MSI card with the same 900/1000 MHz and detailled information on TCMG about XFX cards with 875 (XT edition) and 900 MHz chip frequency (XXX edition), however at a constant 975 MHz memory frequency.

The HD 4890 seems to have a sound frequency potential, so that the partners can present faster variations from the start on, getting Nvidia into difficulties, although we speak of overclocked GTX 275 cards here.
The several times suggested 1 GHz chip frequency seems to be the tip of the iceberg; but 900 to 950 MHz should be manageable for many cards. In comparison to the less frequency-liking HD 4870 there are 20 to 26 per cent more frequency anyway.
