Tipster @momomo_us recently revealed rumored specs for an upcoming Intel Ice Lake Xeon SP SKU. The purported server part features 40 cores, running at 2.3 GHz, along with support for 8-channel DDR4 memory and 64 PCIe 4.0 lanes.
While this sounds like a step up from current-generation Cascade Lake Xeon parts, the trouble comes when comparing this Ice Lake CPU to AMD's current and upcoming EPYC parts. The EPYC Milan lineup, set to arrive this year, will largely be a match in terms of feature set, while Zen 3's higher IPC and 7nm lithography could mean lower power costs.
More worrying yet is the fact that AMD's Zen 4-based EPYC Genoa is just on the horizon. By moving down to the 5nm process, power efficiency looks to be a big step up, and when added to generational IPC improvements, and enhanced platform capabilities like DDR5 support, the total cost of ownership difference could leave Intel's Ice Lake server parts in a tight spot.
