Intel will launch the next generation Xeon Xeon server platform later this year, codenamed 'Cascade Lake ', Still 14nm process, still up to 28 core 56 threads, compared to the radical AMD EPYC Xiaolong has no advantage in some key specifications, but in terms of memory, Intel wants to worry.
The current Skylake-SP Xeon expandable family supports six channels of DDR4 memory, up to two memory banks per channel, up to 12 channels in a single channel, and a maximum capacity of 1.5TB - AMD EPYC already supports up to eight channels, 2TB.
The memory support of the Cascade Lake era is still six channels, up to 12, but with the support of the Proud Optane DIMM, the capacity and performance will be on a step.
The arrogant memory stick officially called 'Optane Persistent Memory DIMM ' (codenamed Apache Pass), different from the previous SSD solid state drive style, this time is the same DIMM memory strip style as DDR4, single capacity 128GB, 256GB, 512GB, and can be mixed with DDR4 in the same system.
If Cascade Lake chooses to match six 128GB DDR4s and six 512GB Optane DIMMs, the total capacity will be 3.84TB, which is more than doubled now, and far exceeds AMD EPYC. A 2U 4-node server system can even have more than 30TB of memory. .
After one or two years of production of a single 256GB DDR4, Intel can implement a single-channel system. 4.6TB Large memory!
