Intel 3rd Gen Xeon Scalable (Ice Lake SP) review: big, small, competitive



Section by Ian Cutress

The release of Intel’s Ice Lake Xeon Scalable processors has been popular for years. Intel’s 10nm process delays caused several failures in Intel’s proposed 10nm product line, especially the high-performance Xeon family: Trying to build 660 mm2 silicon in the process was tough at good times, but Intel had 10nm. In a place where large Xeon processors could begin to be economically retailed and Intel’s official launch today 3.Rd Generation Xeon Scalable is on the back of more than 200,000+ units shipped to major customers to date. The new flagship, the Xeon Platinum 8380, has 40 cores, has PCIe 4.0, and takes advantage of IPC gain in Intel’s Sunny Cove processor cores. We are testing it with the best on the market.

3 IntelRd Generation Xeon Scalable: 1
0nm Goes Enterprise

Today, Intel is launching a full line of CPUs under 3Rd Generation Xeon Scalable Ice Lake is built on a 10nm process.These processors, up to 40 cores per socket, are designed for single socket and dual socket systems only, competing in the market with options. x86 and other Arm’s available with this new generation, Intel’s offering aims to double it: first, upgrade the version compared to 2.nd Gen, but also telling a story about selling a solution rather than selling the processor.

Intel messaging with the new Ice Lake Xeon Scalable (ICX or ICL-SP) avoids simple single core or multicore operations, and is a unique set of features such as AVX-512, DLBoost, the accelerating acceleration. Encrypted and secure By tweaking the right software or pairing it up with an expert Intel family of products such as Optane DC Persistent Memory, Agilex FPGAs / SmartNICs or 800-series Ethernet, it offers better performance and better metrics for those who actually buy the system. Intel believes it is better positioned than competitors who offer only some of these features that limit or lack the infrastructure to integrate them under a single, easy-to-use brand.


Ice Lake Xeon processor wafer 10nm 40 cores

However, the release of the new generation and its expanded portfolio guarantees that the product will be tested for real-base performance claims.This version of the Xeon Scalable, Intel’s first 10nm model, uses a newer architecture than the Sunny. Cove core The benefits of this core, as explained by Intel, begin with an extra 20% raw performance boost, enabled over a much wider core, with an improved frontend and more operational resources. In addition to the core, the memory bandwidth was improved both by increasing the memory channel from six to eight. But also with new prefetching techniques and memory tweaks that increase bandwidth by up to 100% with 25% efficiency. Mesh connections between cores also use the derived algorithms. Improvements to feed IO to and from the cores, and Intel is promoting better power management through independent power management agents within each IP block.

On top of that, Intel is laying out the acceleration features, stating that with raw performance, software optimized for these accelerators will get a better boost than the others. This is especially true when it comes to SIMD commands such as SSSE, AVX, AVX2, and AVX-512: Intel enables improved encryption support in ISA, enabling AES, SHA, GFNI, and other commands to run. Simultaneously across all vector instruction sets, AVX-512 has improved frequency during more complex bit operations for ICX with smart mapping between command and power extraction, providing an extra 10% frequency for instructions. All 256-bit additions are Intel’s Speed ​​Select technology, such as performance profiles, base frequency enhancements, turbo frequency enhancements, and core power assistance to ensure maximum core performance or the quality of service during the system. Heavy duty depending on customer needs Other new features include Software Guard Extensions, which enable a maximum 512 GB enclave size per socket on some models.

Sunny Cove Core of Ice Lake: Part 2

The Sunny Cove Core is already on the market, Intel has created a core consumer variant and the Ice Lake Xeon core server variant has a server variant with a bigger cache and slightly different performance point. But it’s a consumer variant we’ve seen and tested as a laptop.The Sunny Cove is part of Intel’s Ice Lake laptop processor lineup, where we reviewed performance back on August 1.St This is 614 days ago, the period between activating the core for the notebook and the activation of the same core. (With upgrades for servers) in the enterprise are hardly unheard of. But indicate Intel’s manufacturing problems.

However, in our testing of notebooks on the Ice Lake core, we saw a + 17-18% raw performance compared to the previous model. But it costs around 15-20% in frequency in cases where the product is truly great in memory-constrained situations where the new memory controller offers a better upgrade over the model. When it comes to this generation of Xeon Scalable processors with new cores, as you can see in our review in non-accelerated workloads, we get a very similar story. As mentioned, consumer hardware is often TDP restricted, especially laptops. With the new Ice Lake Xeon platform, Intel is increasing its maximum TDP from 205 W to 270 W, which also offers additional performance advantages.

Headline Act: Intel’s Xeon Platinum 8380

The chief sheriff of Intel’s new processor lineup is the Platinum 8380, a full-fat 40-core variant.If we put it alongside earlier processors, there are a few key requirements to be aware of.

Among these processors, the new flagship has a number of advantages:

  • + 43% additional cores (40 vs 28)
  • Almost twice the cache
  • PCIe lane increase + 33% (64 vs 48)
  • 2x PCIe bandwidth (PCIe 4.0 vs. PCIe 3.0)
  • Supports 4 times the memory (4 TB compared to 1 TB).
  • Supports SGX Enclave
  • + 7% higher socket-to-socket bandwidth
  • Supports DDR4-3200 Optane DCPMM 200-series.
  • The price is 20% lower … or 100% higher compared to 6258R.

Although we should highlight some of the negatives:

  • TDP increases by + 32% (270 W compared to 205 W).
  • ST frequency decreased (3400 MHz vs.4000 MHz).
  • Decreased MT frequency (3000 MHz versus 3300 MHz).

If we included all cores, specifications, and frequencies (MT), Ice Lake was as efficient as the previous model. Modern high-performance processors tend to perform well out of the top performance window.However, Ice Lake at low frequencies often suggests that Ice Lake has to run closer to its peak performance to stay within a more suitable TDP socket than previous models. As we see in the laptop area.

Features of all Ice Lake Xeon processors

We’ll delve into the different processors on the next page, however, it’s worth noting that some of the key features that will be implemented in Intel’s all new ICL-SP family in ~ 40 new processors, including the highlighted ones. All media, individual network-focused and optimized processors that use all processors include the following:

  • All Ice Lake Xeons will support eight DDR4-3200 slots at 2DPC.
  • All Ice Lake Xeons will support 4 TB of DRAM per socket.
  • All Ice Lake Xeons will support SGX Enclaves (size will vary).
  • All Ice Lake Xeons will support 64x PCIe 4.0 lanes.
  • All Ice Lake Xeons will support three UPI links at 11.2 GT / s.
  • All Silver / Gold / Platinum Xeons will support the Optane DC Persistent Memory 200 series.

In the past, Intel has been producing some of these features, selling more capable features at a higher price. This segmentation is often due to the lack of competition in the market. However, this time Intel found it appropriate to combine some of the segments for consistency. The main thing in my mind is memory support: At the start of the Xeon Scalable family, Intel began to charge more for high capacity memory models. But in terms of the competition now offering 4 TB / sockets at no additional cost, it seems that Intel has decided to combine the stack with a single memory support option.

Intel 3Rd Generation Xeon Scalable: new socket, new motherboard

Ice Lake Xeons now has eight memory slots instead of six, a new socket and a new motherboard will be required.Ice Lake comes with 4189 pins and requires a LGA4189-4 ‘Whitley’ motherboard. This differs from the LGA4189-5 ‘Cedar Island’ used with Cooper Lake, and the two are not compatible, however, they share a power profile.

This brings us to Intel portfolio issues. Technically, Ice Lake 10nm is not the only member of 3.Rd Gen Xeon Scalable Family – Intel sees fit to include both 14nm Cooper Lake and 10nm Ice Lake in the same thread.Intel is splitting the two, stating that Cooper Lake is focused exclusively on high-volume customers who want to deploy systems. Quad sockets and eight sockets with dedicated AI workloads.By comparison, Ice Lake is for the mass market and limited to two socket systems.

Ice Lake and Cooper Lake both have ‘3’ in the third-generation nominal processor names. Users can tell which one is Cooper Lake, as they end up with either H or HL – Ice Lake processors (as we’ll see on the next page) .No H or HL, most Cooper Lake processors are Platinum models anyway. With a few Xeon Golds As we read this review, we’re only going to focus on Ice Lake, as this is the platform Intel sells to the mainstream.

This review

In the lead up to today’s launch, Intel has provided two popular Ice Lake Xeon 2U systems: we have the dual 40-core Xeon Platinum 8380s! In the meantime, we also spent time with Supermicro’s Dual Xeon Gold 6330 system, which had a 28-course processor and did a good job of comparing it with the previous Xeon Platinum 8280.

Our review today will look at stack processors, benchmarks, power analyzes, memory analyzes, and some preliminary conclusions.
