AMD Launches the ATI Radeon™ HD 4770


AMD today launched the ATI Radeon™ HD 4770 graphics processor, a groundbreaking product that harnesses the state-of-the-art 40 nanometer manufacturing process for the desktop PC market, delivering best-in-class performance and energy efficiency at anticipated launch prices as low as $99.

“Consumer pressure in this economic downturn is shifting demand to lower prices and the price band around $100 has the highest demand and highest volume,” said Rick Bergman, senior vice president and general manager, Graphics Products Group, AMD. “AMD has responded with the launch of the ATI Radeon HD 4770, targeting this market with cutting-edge technologies like 40 nm processors, support for DirectX 10.1 gaming and GDDR5 memory."

The card performs better than Geforce 9800GT and it's slightly slower than the Radeon HD 4850, but at the same time, it runs cooler than the HD 4850. It is a dual slot graphics card and it has an external power connector, but the best attribute will definitely be the performance you get for the price.

AMD releases new Phenom II X4 945 and 955 BE


AMD will now refresh the lineup with two new processors: the Phenom II X4 955 Black Edition and Phenom II X4 945. Both processors are modestly priced, with the Phenom II X4 955 Black Edition at $245, and the Phenom II X4 945 at $225.

The 955 Black Edition and the 945 are clocked at 3.2GHz and 3.0GHz, respectively. Black Edition processors have unlocked multipliers to make overclocking easier for PC enthusiasts. The processors differ only in clock speed, and have identical specifications otherwise. The Phenom II X4 processors will come with 64K of L1 instruction and 64K of L1 data cache per core (512KB total L1 per processor), 512KB of L2 data cache per core (2MB total L2 per processor), and will also have a shared 6MB L3 cache.

The two new processors are based on AMD's AM3 socket but will also work in most AM2+ motherboards. Because they support both sockets, the processors also support both DDR2 and DDR3 memory, respectively found in AM2+ and AM3 socket based motherboards. Using DDR2 the processors will have 17.1GB/s of memory bandwidth, and using DDR3 the bandwidth jumps up to 21.1GB/s. Older Phenom II X4 processors, like the 940 Black Edition and the 920, use AMD's AM2+ socket.

The Web site Ripping.org notes that hobbyists with early access to the X4 955 BE chip have been able to clock it at up to 6.7 GHz.
