According to Mark Liu, senior analyst at DRAMeXchange, enterprise servers contribute to around 60% of the global server shipments, while hyperscale server applications account for around 30%. The demand for micro servers used in edge computing is projected to see significant growth in the next 3 to 5 years due to the construction of data center and the implementation of 5G after 2020. This trend is also expected to drive the demand for related components and DRAM products considerably.

Currently, x86-based solutions are still the market mainstream, while the penetration rate of Intel’s Purley platform has reached about 50%. Meanwhile, AMD has been migrating to products based on 14nm process. Previous product lines will be phased out as the wafer starts of 14nm process gradually increase. As for ARMv8 and RISC architecture, products are built to order at this stage with small production volume, mainly for the data center market. These two architectures are not able to compete with x86 servers until 2020, but may be adopted in more applications after that as the penetration rate of micro servers increases.

In terms of the product roadmap, Intel's Cascade Lake will still be based on the third-generation 14nm process, but would not become the mainstream until the second half of 2019. AMD's new solution will migrate to the 7nm process, with its EPYC Series becoming the main product line this year. The AMD Rome platform server processor will also have a chance to come onto the market in the second half of next year.

DRAMeXchange notes that, the penetration of new platforms may drive the average content per box. The average density of DRAM in servers will continue to see 20% annual growth in 2019.
