Even though the company doesn't like to boast clocking records, AMD is actually the first company to have products reaching the clock speed of 1 GHz.

• During Comdex 1999 in Las Vegas, AMD and Prometeia demonstrated a vapor-chamber cooled AMD Athlon 650 CPU running at 1GHz. This was the first CPU to reach 1GHz clock.
• On March 6th, 2000 - AMD introduced Athlon 1000 MHz. Developed under codename "Magnolia", this was the first CPU you could purchase in stores with a clock speed of 1 GHz.
• On October 6th, 2005 - Sampsa Kurri and Ville Suvanto, two young Finnish overclockers managed to overclock ATI Radeon X1800 to 1.003 MHz, the first GPU to pass 1.0 GHz mark.
• On May 13th, 2009 - AMD introduced ATI Radeon HD 4890, the world's first GPU with a stock clock of 1GHz for the GPU. 

We can argue can nVidia GeForce 8800GTX count, because it has shader cores clocked at 1.2 GHz [November 13th, 2006], but AMD is the first with the GPU clocked at 1 GHz.

First to GHz with CPU, first to GHz with a GPU - BSN* wishes to congratulate to all engineers who made this feat possible. Today guys and girls, you made history.

ATI Radeon HD4890 was known as Super RV790 to ATI partners, and it is consisted out of speed-binned RV790 chips, modified PCB and air-cooler. Bear in mind this is not a limited run, like the previous Super RV770 [water-cooled edition, was only available from Sapphire, ASUS and MSI], but all of ATI's partners will carry the model.

Sapphire stole the limelight with its Atomic Edition, vapor-chamber cooled card packed in a neat aluminum box. Guys jumped the gun last week, and now the first reviews are coming out. We are expecting our sample to arrive soon, and we plan to bring you a review of 4980 during next week.
