Radeon HD 4890 Atomic edition packs 1GHz GPU

Written by IT News on 11:26 PM

Advanced Micro Devices has recently announced several new additions to its computer equipment layout, including the highly anticipated RV790-based Radeon HD4890 graphics card.

One of the main features of the latest high-performance, single-GPU video card is that it will provide PC enthusiasts with a GPU that can go as high as 1 GHz per core, even though the reference board comes with a GPU speed of 850MHz.

Fortunately, they are always looking for the ultimate in performance GPU, Sapphire, one of AMD's main partner, is expected to launch of the Radeon HD4890 Atomic Edition.

The card comes with a GPU pumped out working at an impressive 1000MHz per core, while the memory is set to 4200MHz.

The huge boost in clock rates of this card will certainly enthusiasts with the performance required to run all the latest gaming applications at high resolutions, especially since this card is over kill for ordinary end users.

The card has a massive dual-core cooling solution and six pin and eight pin power connectors. Compared with the reference card, the Radeon HD 4890 Atomic edition has the further eight pins, replacing the six-pin connector on the standard model. Using Sapphire's Vapor-X cooling technology, the Atomic card promises to deliver the performance you expect from AMD's fastest single-GPU card on the market.

Unfortunately the map is not official and Sapphire continues to communicate it to the market. But if you think a reference Radeon HD4890 has a starting price point of U.S. $ 235, you can expect something like U.S. $270 - U.S. $300.

New Sapphire Vapor-X HD 4850 card

Written by IT News on 11:53 PM

Sapphire Technology, a leading graphics card manufacturer has recently announced the introduction of the new Vapor-X series of graphics cards, new versions of the Radeon HD 4870 and HD 4850th The new cards are on the same PCB as the company's current models, but the new sport-Vapor-X cooling solution, "said a quieter, more efficient cooling than AMD's mainstream-performance Graphics Processing Units. The new Vapor-X series comes with a new, independent design, the two great appearance and performance.

According to the company, the new SAPPHIRE HD 4870 Vapor-X Edition offers a choice of either a full 2 GB or 1 GB of GDDR5 memory, with the clock frequencies to operate at 750MHz and 900MHz for the GPU and memory. Mainstream Performance Sapphire HD 4850 Vapor-X Edition comes with a total of 512 MB GDDR3 memory clock of 993MHz while the GPU core speed was a cool 625MHz.

Both cards are equipped with solid capacitors and Sapphire "Black Diamond" Heat sinks that increase efficiency and reliable operation. According to Sapphire, Black Diamond valve with integrated heat sink is 10 percent cooler and 25 percent more power efficient than conventional reactors.

The Vapor-X cooling solution based on a Vapor Chamber Technology, the same principles as heat pipe technology. The solution works with a liquid refrigerant evaporates is that on a hot surface, resulting steam then condenses on a cold surface, and the liquid is then put back on the hot surface. This process takes place in a vacuum chamber with a wick system.

Price as new Vapor-X Radeon HD 4850 can be found for around 150 Euros, while the 1 GB and 2 GB versions of the Radeon HD 4870 cards go for around 220 Euros and 250 Euros, respectively.
