The upcoming Intel Barlow Pass Optane memory modules are likely to receive support for 3200MT / s-ddr4. This is evident from a leaked slide from Intel. The modules are also said to have improved bandwidth compared to Apache Pass.
The slide was discovered by Twitter user Komachi_Ensaka. Barlow Pass dimms Optane DC Persistent memory modules. The modules must provide high capacities with support for data persistence, and are therefore primarily intended for use in data centers. The dimms fit in ddr4 slots. Barlow Pass uses the second generation 3D XPoint memory with a bit density up to four layers, reports Tom’s Hardware.
The upcoming Barlow Pass dimms should offer speeds of up to 3200MT / s with a tdp of 15W, according to the slide. Bandwidth is also said to have improved by up to 15 percent over its predecessor, Apache Pass. Current Apache Pass modules also support maximum speeds of up to 2666MT / s. Barlow Pass memory modules also receive blue heat spreaders, which should make the modules more recognizable in data centers. Current Apache Pass dimms have black heat spreaders.
According to the slide, Intel is coming with two versions of Barlow Pass: one for the Whitley platform and one for Cedar Island. The latter supports up to 2933MT / s dimms, with 3200MT / s as stretch target. Whitley supports eight channel memory and up to 4TB of memory per CPU sockets. Cedar Island, in turn, supports up to 3TB per socket and six-channel memory, the slide shows.
Tom’s Hardware writes that Whitley did it mainstream platform for Cooper Lake and Ice Lake SP processors. These CPUs should be released this year. Cedar Island is believed to be for four-socket platforms.
It is still unclear when the first Barlow Pass memory dims will be released. Earlier this year, Intel stated that the Barlow Pass is in 2020 ‘prqmust achieve. This means that Intel expects to produce the first modules this year.
