ATI Radeon HD 4890 overclocked to 1000MHz

Posted on Tuesday, March 24 2009 @ 20:42:19 CET by


An Asian report suggests the ATI Radeon HD 4890 (RV790) will have good overclocking headroom. Techpowerup spotted a forum post at Chinese tech site PCInLife of an overclocked who benched the RV790 with the core at 1GHz and GDDR5 memory at 4500MHz. Standard cards are reportedly clocked at 850MHz with 3900MHz GDDR5. TPU believes ATI may be planning to release overclocked RV790 SKUs.
It has surfaced on the forums of Chinese tech community PCInLife, that the RV790 rather effortlessly reached the 1 GHz mark, the slider-limit of Catalyst Control Center, sparking off fresh rumors that AMD partners may be creating a fresh niche of highly-overclocked cards shortly after Radeon HD 4890 comes to be. The overclocker reached speeds of 1 GHz (core) and 1125 MHz (4.50 GHz effective, memory). At the said speeds, the card was put through 3DMark Vantage with its eXtreme settings. It churned-out a score of X5480, which puts its performance somewhere between those of the GeForce GTX 280 and GeForce GTX 285. It should also be taken into account that the drivers RV790 users the world over have been using, are preliminary beta drivers. AMD plans to release Catalyst 9.4 with the release of Radeon HD 4890, which just may impact positively on the performance of the product.
