DDR4 is early: Intel will support it in 2014

The standard specification of DDR4 memory has been basically completed. Samsung, Hynix, etc. have all completed samples one after another. However, because DDR3 is in the midst of its prime, DDR4 will not rush. According to the latest news, DDR4 memory was first used in the server space in 2014, and then entered the desktop in about a year and a half.

It is reported that Intel's next-generation enterprise server platform Haswell-EX will be the first to integrate DDR4 memory controller. Haswell-EX and Haswell, which we often look forward to, belong to the same family. For large enterprise areas such as data centers, there are up to 16 cores and four are 64 cores. DDR4 memory will not only bring about a significant increase in frequency (up to 4266MHz), but also 1.2V low voltage, better peer protection and error recovery technologies. These large-scale applications can be seen in servers and enterprise centers. Immediate benefits.

On the desktop, the 22nm Haswell and 14nm Broadwell all use the same LGA1150 package interface. The memory controller is naturally limited to DDR3. DDR4 support is likely to wait until the new 14nm architecture "Skylake" is around 2015. Year of things.

Such a pace may not be fast, before market research institutions once believed that DDR4 memory should be basically universal by 2015. However, it is not necessarily a good thing to upgrade too quickly. Everyone can enjoy cheap DDR3 with more peace of mind.

In addition, if you are worried that Haswell, Broadwell will therefore do nothing in memory performance, it is not necessary, because the frequency of a DDR3 will certainly be higher and higher, the two generations of the new processor will have ultra-low latency internal memory The new features of the controller bus and brush functions, such as floating-point peak emissivity, FMA operation, and four-level cache, all contribute to better memory performance.
