Confrontation of such “iron” giants as Intel and AMD will not end, probably never. Companies regularly update their processor lines, adding new features, improving process technology and making their products more and more powerful and interesting for various categories of users. And now a new stage of this technological race has begun. And Intel enters it with a processor carrying on board as many as 48 cores.

The new announced processors belong to the Xeon Scalable family and have the subtitle Cascade Lake. Just want to note that Cascade Lake is not a consumer solution and is intended primarily for server stations and, according to Intel representatives, for artificial intelligence systems. Something similar from Intel could have been expected, given the fact that AMD is already planning to be the first company to launch a 7-nanometer chip next year. While Intel itself has problems with this architecture.

Xeon Development Director Lisa Spelman told some details about future devices. If we summarize everything said to her, then Intel, in contrast to AMD with its 7-nanometer processors, wants to “squeeze” two processors, created using 14-nanometer technology, into one. And this is not the first time that a company does this. Back in 2005, after AMD launched the first dual-core Opteron X86 server processors, Intel prepared Xeon DP Paxville chips, its first implementation of a multi-core module (MDM) in the Xeon line as an explicit temporary measure.

he new processors, in addition to the 48 cores on board, will have a 12-channel DDR4 memory controller. According to internal tests, the 48-core processor in Linpack is 3.4 times faster than the AMD Epyc 7601, and 1.3 times faster in the Stream Triad test. As stated by Ms. Spelman,

“Our main goal is to provide leadership in performance throughout the entire 2019.”

At the same time, there were no other characteristics of the new processors. And, as noted by The Next Platform, this is a rather strange decision, given that new devices should appear in early 2019. In addition, our colleagues also pay attention to the fact that MDM is likely to make the power consumption of processors quite high due to the fact that, in fact, there will be two processors on one core. And the test data confirms this: in the already mentioned Linpack Cascade Lake consumes 21% more energy than the Xeon SP-8180M processor with 28 cores operating at 2.5 GHz.
