The upcoming line of Intel processors, named as “Cascade Lake” is still not fully reviled, but some of the key features are slowly emerging on several hardware websites, and one of them is the above mentioned capacity. At this point some of us still believe that 128GB of RAM is the limit, but Intel is doubtful and wants to reach numbers as high as 3.84 TB of memory per socket. With that in mind, one question remains: how can a tech leader in CPU’s and SSD’s actually manage to expand the RAM market?
Try to understand Optane DIMM’s, and then combine them with conventional RAM
A year ago Intel posted a photo of a setup which featured a Cascade Lake CPU, combined with six DDR4 DIMM’s and six Optane Persistent Memory DIMMs per socket. To much surprise, the Optane memory wasn’t your regular piece of SSD, but rather the next logical step in RAM. Intel introduced three different models, featuring 128GB, 256GB and 512GB of storage option. To understand it better, try to imagine a product which is in-between conventional DRAM and a fast SSD.
The benefits are several, not only are you able to ignore the current limitation of RAM slots on the majority of motherboards and bulk up to 3.84 TB of memory per socket, with a total of almost 8 TB of RAM, but also have an overall faster system, with a special focus on servers with Xeon setups. Now with that in mind, Intel will target servers that run databases which can and will benefit from such high capacities of available memory.
The only downside is that it will cost – a lot. We’re talking about $3500 for one single 128GB LRDIMM, and keep in mind that you still need the rest of the setup. But regardless of the price, it’s nice to see where the future is going. Soon enough we will have CPU’s with 64 cores, monster GPU’s and several terabytes of RAM, just to play Minecraft on it.
