Asus' Radeon HD 4890 enables 1000Mhz Overclock on GPU

With little alteration of the operating voltage ASUS Radeon HD 4890 will be capable of reaching 1000MHz GPU frequency, which is anything but poor. That Radeon HD 4890 will be a good overclocker overall is no secret, but ASUS has really outdone itself to make its version stand out. The memory department seems to be unchanged, but it is very much possible that the more powerful power circuitry will have a positive effect here as well.

Our source also revealed that we will see factory overclocked Radeon HD 4890 cards with GPU clock frequencies beyond 900MHz, but whether it was talking about the renowned "Extreme" edition of HD 4890 was not made clear.
