Intel Finally Launches Its 3rd Gen Ice Lake-SP Xeon CPU Lineup: 10nm Server Chips With Up To 40 Cores, 270W TDP, 64 PCIe Gen 4.0 Lanes & More

Submit

Today finally marks the official launch of Intel's 3rd Gen Ice Lake-SP Xeon CPUs which will be the company's first server lineup to be made on the 10nm process node. The Ice Lake-SP lineup aims at the server segment and will be competing against AMD's EPYC Milan family which launched last month.

Intel 3rd Gen Ice Lake-SP Xeon CPUs Officially Launched - 10nm Comes To Servers With Up To 40 Cores, 270W TDP, 64 PCIe Gen 4.0 Lanes & More

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.

Intel Alder Lake-P Mobility CPUs Spotted With Benchmarks, 14 Core With 20 Threads & 8 Core With 12 Thread SKUs

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

Some of the major highlights of today's Intel Xeon announcement include:

  • New 3rd Gen Intel Xeon Scalable processors — combined with Intel’s portfolio of Intel® Optane™ persistent memory and storage, Ethernet adapters, FPGAs, and optimized software solutions — deliver performance and workload optimizations across hybrid-cloud, high-performance computing (HPC), networking, and intelligent edge applications.
  • New 3rd Gen Intel Xeon Scalable processors feature a flexible architecture with integrated artificial intelligence (AI) acceleration with Intel® DL Boost technology, plus advanced security capabilities to protect data and application code with Intel® Software Guard Extension (Intel® SGX) and Intel Crypto Acceleration.
  • New 3rd Gen Intel Xeon Scalable processors are rapidly ramping, having shipped more than 200,000 units for revenue in the first quarter of 2021 with broad industry adoption across all market segments, including the world’s top cloud service providers set to deploy services; more than 250 design wins within 50 unique OxM partners; more than 15 major telecom equipment manufacturers and communications service providers readying POCs and networking deployments, and over 20 HPC labs and HPC-as-a-service environments leveraging our latest Xeon Scalable processors.

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.

Intel's Xeon Ice Lake-SP lineup is split between Platinum, Gold, and Silver SKUs. The top SKU is said to be the Xeon Platinum 8380 which would feature 40 cores, a base clock of 2.30 GHz, and a 270W TDP. Compared to AMD's flagship, we are looking at lower cores and a lower base clock however, Intel's architecture and process nodes are tuned for higher clock speeds so that might mark a small win for the blue team. Intel is also placing bets on its AVX-512 instruction set and has shown CPU benchmarks where it handily beats AMD's existing Rome CPUs but only when running applications that fully leverage AVX-512 instructions. Standard applications would not see the same benefit on Intel CPUs.
