Intel 3rd Gen Xeon Ice Lake-SP CPU Rumors – 10nm With Up To 40 Cores, 8-Channel DDR4-3200, 64 PCIe Gen 4.0 Lanes, Max 270W TDP
A couple of rumors regarding Intel's Ice Lake-SP Xeon server CPUs have surfaced over the web, mostly from known leaker, Momomo_US. The information consists of specifications, configs & power ratings of several SKUs that will be part of the 3rd Gen Xeon Scalable processor family.
Intel 3rd Gen Ice Lake-SP Xeon CPU Rumors Point Out Up To 40 Cores, 270W TDPs & Brand New Core Architecture
Starting off with the details, Intel's 3rd Gen Ice Lake-SP Xeon CPUs will be based on the 10nm+ process node and utilize the Sunny Cove core architecture. The Intel Sunny Cove x86 architecture has been around since 2019 and was first featured on Intel's 10th Gen Ice Lake processors for the notebook segment. Intel has since moved over to Tiger Lake which is based on the Willow Cove x86 architecture and makes use of the 10nm SuperFin process node.
Some of the major upgrades that Intel's 10nm+ for Ice Lake-SP Xeon CPU will deliver include:
- 2.7x density scaling vs 14nm
- Self-aligned Quad-Patterning
- Contact Over Active Gate
- Cobalt Interconnect (M0, M1)
- 1st Gen Foveros 3D Stacking
- 2nd Gen EMIB
XCC : 16/18/28/32/36/38/40C
HCC : 8/12/16/18/20/24/26/28C
TDP : 105/135/150/165/185/205/220/235/250/270W

According to the rumor, Intel's Ice Lake-SP will ship in two die configurations, XCC (Extreme Core Count) and HCC (High Core Count). The XCC SKUs will feature 16, 18, 28, 32, 36, 38, and up to 40 cores. The HCC SKUs will feature 8, 12, 16, 18, 20, 24, 26, and up to 28 cores. The TDPs will range from 105, 135, 150, 165, 185, 205, 220, 235, 250, and all the way up to 270W for the flagship SKU. The XCC variants with 32, 36, 38, and 40 cores will be configurated at around 205-270W TDPs. As for clock speeds, one 40 core SKU is mentioned to feature a base clock of 2.30 GHz however the boost clock is unknown.
There was a recent entry for a 38 core and 76 thread Intel Ice Lake-SP CPU known as the Xeon Platinum, 8386Q within the Geekbench database which was running in a dual-socket configuration. This means that you are looking at 76 cores and 152 threads. The CPU features 57 MB of L3 cache, 23.75 MB of L2 cache, and a maximum of 64 PCIe Gen 4 lanes. There was a total of 256 MB of DDR4 EEC memory attached to the system.
Looking at the performance, we see a score of 801 points in single-core and 17529 points in the multi-core tests. These results are nothing spectacular and while we cannot provide you with a comparison against EPYC 7002 or 2nd Gen Xeon processors due to inconsistent operating systems and benchmark versions, we can tell that the Intel Ice Lake-SP chip in its current state is just on par with AMD's Rome lineup. And with Milan launching soon, Intel's hopes for Ice Lake-SP succeeding in the server segment look really grim.
