Sapphire Radeon HD 4890 1GB Review

Overclocking Results


Unlike most other graphics cards on the market, ATI seems to be actively marketing the HD 4890’s overclocking abilities. Please note that we used the stock cooler with the default fan speed. Without the support of other aftermarket overclocking tools, we were somewhat limited by the Catalyst Control Center’s self-imposed overclocking limits but that didn’t stop us from getting some downright jaw-dropping results.

Final Core Overclock: 1Ghz
Final Memory Overclock: 1200Mhz (4800Mhz effective)

Sweet merciful Lord. Impressive isn’t it? And to make matters even better, we maxed out the Catalyst sliders which means this puppy has even more left in the tank! Considering we are now hearing reports that some manufacturers (like Sapphire) will be releasing cards which have a pre overclocked core running at 900Mhz or even 950Mhz, we have to wonder what the limit is on these cards. Not only did the core hit the 1Ghz mark but the memory is now flirting with the magical 5Ghz mark.
