去年十二月左右公開了這個世界最快繪圖記憶體後，Samsung 這幾天正式宣佈了開始大量生產的計畫，不過距離要降臨各位的顯示卡還是有一段時間好等就是。

這個急驚風 GDDR5 記憶體，理論上最高的資料傳輸可達 7.0 Gbps，同時最大頻寬可達 28 Gbps，另外根據 Samsung 的官方說法，採用 50nm 製程，也讓記憶體製造生產的效率成長 100%，同時記憶體的工作電壓降到 1.35 伏特，跟 GDDR4 相比，則少了 20%。

而雖然說 Samsung 他們表示將會把 50nm 的製程技術，在今年年底以前，延伸到其他的記憶體產線，不過目前廠商還是只有 32Mb x 32 的配置可以選（或者可以改成 64MB x 16）

最後，則是期待 GDDR 後面數字超過 MP 的一天！衝吧！三星！（誤）

Samsung Begins Mass Production of High-performance GDDR5 Memory Using 50-nm Class Process Technology

Samsung Electronics Co., Ltd., the world leader in advanced memory technology and the leading producer of high-end graphics memory, announced today that it has begun mass producing GDDR5 graphics memory using 50-nanometer class process technology.

"Our early 2009 introduction of GDDR5 chips will help us to meet the growing demand for higher performance graphics memory in PCs, graphic cards and game consoles," said Mueez Deen, director, mobile and graphics memory, Samsung Semiconductor, Inc. "Because GDDR5 is the fastest and highest performing memory in the world, we're able to improve the gaming experience with it across all platforms," he added.

Designed to support a maximum data transfer speed of 7.0Gbps (gigabits per second), Samsung's GDDR5 will render more life-like (3D) imaging with a maximum 28GB/s (gigabytes per second) bandwidth, which is more than twice that of the previous fastest graphics memory bandwidth of 12.8GB/s for GDDR4. The ultra-fast processing speed is equivalent to transferring nineteen 1.5GB DVD resolution movies in one second. The high image processing speed of the GDDR5 also supports the latest data formats (Blu-ray and full HD).

Unlike GDDR4, which processes data and images using the strobe-and-clock technique, the processing speed of the GDDR5 is much faster because GDDR5 operates with a free-running clock that does not require the data read/write function to be synchronized to the operations of the clock.

By adopting 50nm class technology, Samsung expects production efficiency to rise 100 percent over 60nm class technology. In addition, Samsung's GDDR5 operates at 1.35 volts (V), which represents a 20 percent reduction in power consumption compared to the 1.8V at which GDDR4 devices operate.

Now available in a 32Megabit (Mb) x32 configuration and also configurable as a 64Mb x16 device, Samsung expects GDDR5 to account for over 20 percent of the total graphic memory market in 2009. The company also said it plans to expand the 50-nm process technology throughout its graphics memory line-up this year.
