SK Hynix and Intel jointly released a white paper on the performance verification of DDR5 applied to Intel cpus； SK Hynix DDR5 DRAM improves server bandwidth by 70% and reduces power consumption by 14.4% compared to the previous generation； SK Hynix plans to accelerate its performance improvement in the second half of the year by focusing on DDR5 DRAM, which has obtained performance certification, as its main product

On September 14, SK Hynix announced a white paper with Intel Corporation (Intel), which confirmed that the performance of SK Hynix DDR5 server DRAM equipped with Intel CPU has reached the industry leading level. The white paper was released simultaneously on the official websites of SK Hynix and Intel.

The two companies have worked closely together since the DDR5 DRAM development phase. The white paper describes the results of performance verification of the 4th Gen Intel® Xeon® Scalable Processor (4th Gen Intel® Xeon® Scalable Processor) with DDR5 DRAM over the past eight months.

In recent years, there has been an increasing demand for low-power, high-performance semiconductors in the server industry. The white paper emphasizes that the two companies will jointly open a new era of data center evolution by providing industry-leading memory and cpus with both performance and energy efficiency.

According to the white paper, the performance of Intel's fourth-generation Xeon processors is 2.9 times better than that of the third-generation Xeon processors. At the same time, the power consumption of SK Hynix DDR5 DRAM is 14.4% lower than that of DDR4 DRAM. In particular, in terms of the power to performance ratio (power to performance ratio) 3, DDR5 is 1.22 times higher in Integer computing and 1.11 times higher in Floating Point computing than DDR4 in servers with fourth-generation Xeon processors.

Therefore, the two companies predict that if server customers build data centers using fourth-generation Xeon processors and DDR5 in the future, it will help improve energy efficiency and build sustainable data centers. In addition, by operating the data center efficiently, the customer's total cost of ownership (TCO) 5 is also reduced.

"As shown in the white paper, the server equipped with Intel CPU and SK Hynix DDR5 DRAM has faster data processing speed and lower power consumption compared to the previous generation," said Yoo Sung-soo, vice president of DRAM product planning at SK Hynix. "Especially in applications such as Generative AI, we can effectively use high-density DRAM that needs to process massive amounts of data."

"We expect our server chip customers to benefit from the important data provided by the white paper to effectively help their business development," added Yoo.

Dr. Dimitrios Ziakas, vice president of Memory and IO Technology at Intel, said: "Intel has been working with SK Hynix and others in the industry to achieve the best operating environment and performance for DDR5 with the fourth-generation Intel ® Xeon ® scalable processor. These efforts are aimed at delivering robust data center system solutions with superior performance and energy efficiency to benefit our mutual customers."

SK Hynix plans to continue to strengthen its product layout in the server market through the latest cooperation project with Intel. As the demand for DRAM is expected to increase in the second half of the year, the company plans to strengthen its market-leading competitiveness with the fourth generation (1a) and fifth generation (1b) DDR5 DRAM as its main products and accelerate its performance improvement.
