Intel’s third-generation Xeon Scalable (Ice Lake SP) evaluation: handed down from generation to generation, less competitive



Part of Ian Cutress

The release of Intel’s Ice Lake Xeon Scalable processor has been going on for many years. The delay of Intel’s 10nm manufacturing process has caused many setbacks for all 10nm product lines proposed by Intel (especially the high-performance Xeon family): It is difficult to try to manufacture 660 mm2 silicon on the process at the best time. But Intel started selling large Xeon processors where it is economically feasible, and it has 10nm space. Today, Intel’s No. 3 processor was officially released.rd To date, Xeon Generation’s scalable products have been delivered to more than 200,000 major customers. The new flagship Xeon Platinum 8380 has 40 cores, provides PCIe 4.0, and takes advantage of the IPC gain of Intel Sunny Cove processor cores. We are testing the best products on the market.

Intel 3rd Xeon generation is scalable: 1
0nm enters the enterprise

Today, Intel is launching a complete processor stack under level 3 processors.rd The Xeon generation scalable Ice Lake brand is built on its 10nm process. These processors (up to 40 cores per socket) are specifically designed for single-socket and dual-socket systems and compete with other x86 and Arm options on the market.In the new generation of products, Intel’s product goals are twofold: first, compared with the second generation of products, the second generation of products is improvednd Gen, but also narrated around selling solutions instead of simply selling processors.

Intel avoids simple single-core or multi-core performance with its new Ice Lake Xeon Scalable (ICX or ICL-SP) messaging, but instead has a unique feature set such as AVX-512, DLBoost, encryption acceleration and security, and Through appropriate software optimization or pairing with professional Intel family products (such as Optane DC permanent memory, Agilex FPGA/SmartNIC or 800 series Ethernet), it can provide better performance and better indicators for those who actually buy the system . Intel believes that Intel is in this advantage compared to competitors that only provide a limited subset of these features or lack the infrastructure to integrate these products into an easy-to-use brand.


A 40-core Ice Lake Xeon 10nm processor chip

Nevertheless, the introduction of a new generation of products and an expanded product portfolio ensure that the product has actually been tested against its original performance requirements. Intel’s first 10nm Xeon scalable product uses a newer architecture Sunny Cove core. As explained by Intel, the advantage of this core is first of all an increase of the original performance by 20%, thanks to a wider core, an improved front end and more execution resources. In addition to the core, by increasing the storage channels from six to eight, not only the memory bandwidth is increased, but also the new memory prefetching technology and optimization technology are adopted, which can increase the bandwidth to 100% and improve the efficiency. 25%. The mesh interconnection between the cores also uses updated algorithms to provide IO to and from the core, and Intel is promoting better power management through independent power management agents inside each IP module.

Most importantly, based on the acceleration function, Intel pointed out that in terms of original performance, the software optimized for these accelerators will have a better improvement than the new generation. This starts with the basic core layout, especially when it comes to SIMD commands such as SSSE, AVX, AVX2, and AVX-512: Intel is better supporting encryption through its ISA so that it can run AES, SHA, GFNI and other instructions At the same time on all vector instruction sets, AVX-512 increases the frequency during ICX’s more complex bit operations, and the mapping between instructions and power consumption is smarter, providing an additional 10% frequency for all 256-bit instructions. The most important is Intel’s Speed ​​Select technology, such as performance profile, basic frequency improvement, turbo frequency improvement and core power assist, to ensure the highest per-core performance or quality of service in frequently used systems according to customer needs. Other new features include Software Guard Extensions. For some models, the security zone per slot supports a maximum of 512 GB.

The Sunshine Bay Core Area of ​​Ice Lake: Part 2

In fact, Sunny Cove core has been put on the market. Intel has manufactured a consumer version of the core and a server version of the core. Ice Lake Xeon has a server version with a larger cache and slightly different optimization points, but this is the consumer version that we have seen and tested in the form of a laptop. Sunny Cove is part of Intel’s Ice Lake notebook processor product portfolio, and we evaluated the performance on August 1.Yingshi 2019, this is 614 days ago. The time interval between enabling a kernel for a laptop and enabling the same kernel for a server (through a server upgrade) in an enterprise is almost unheard of, but it shows Intel’s manufacturing troubles.

Nevertheless, in our notebook test on the Ice Lake core, we saw a performance improvement of +17-18% over the previous generation, but this was at the expense of 15-20% frequency. The real advantage of this product is that in the case of limited memory, the new memory controller provides an improvement over a generation. As you can see in this review, when it comes to a new generation of Xeon scalable processors with new cores, in non-accelerated workloads, we get very similar stories. That being said, consumer hardware is often limited by TDP, especially laptops! With the new Ice Lake Xeon platform, Intel has increased the peak TDP from 205 W to 270 W, which also brings other performance advantages.

Title Law: Intel’s Xeon Platinum 8380

The leader in Intel’s new processor product line is the platinum 8380-full fat 40-core behemoth. If we put it side-by-side with the previous generation processor, we need to pay attention to some key specifications.

Among these processors, the new flagship product has many advantages:

  • Core increase + 43% (40 to 28),
  • The cache has almost doubled,
  • PCIe lane increase + 33% (64 and 48),
  • 2 times the PCIe bandwidth (PCIe 4.0 and PCIe 3.0)
  • 4 times the memory support (4 TB and 1 TB)
  • SGX Enclave support
  • Socket to socket bandwidth increased by 7%
  • Support DDR4-3200 Optane DCPMM 200 series
  • Compared to 6258R, the price has dropped by 20%…or increased by 100%

Although we should perhaps emphasize some negative factors:

  • TDP increase + 32% (270 W vs 205 W)
  • ST frequency reduction (3400 MHz and 4000 MHz)
  • MT frequency reduction (3000 MHz and 3300 MHz)

If we combine the specification table core and the full core (MT) frequency, then Ice Lake actually has the same efficiency as the previous generation product. Modern high-performance processors usually perform well outside the peak efficiency window, but the lower frequency of Ice Lake usually indicates that Ice Lake must be closer to the peak efficiency point than the peak frequency in order to stay within the proper socket TDP. This is similar to what we see in the field of notebook computers.

Features of all Ice Lake Xeon Scalable processors

We will cover the different processors in depth on the next page, but it is worth noting that some key features will be applied to all of Intel’s new ICL-SP series. Among the approximately 40 new processors, including all media-centric parts, network-centric processors, and all individual optimizations used, all processors will have the following characteristics:

  • All Ice Lake Xeons will support eight channels of DDR4-3200 on 2DPC
  • All Ice Lake Xeons in each slot will support 4 TB DRAM
  • All Ice Lake Xeons will support SGX enclaves (size will vary)
  • All Ice Lake Xeons will support 64 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 200 series Optane DC persistent storage

In the past, Intel often productized some of these functions and sold more powerful functions at higher prices. This segmentation is usually caused by the lack of competition in the market. However, this time, Intel has found the right conditions to unify certain market segments to maintain consistency. One of the key points in my mind is memory support: at the beginning of the Xeon scalable series, Intel began to charge extra for the large-capacity memory model. But considering the competition of offering free 4 TB/slot now, it seems that Intel has decided to adopt a memory support option to unify the stack.

Intel 3rd Xeon Generation can be expanded: new slot, new motherboard

Ice Lake Xeons now has eight memory channels instead of six, requiring a new slot and a new motherboard. Ice Lake has 4189 pins and requires an LGA4189-4’Whitley’ motherboard. This is different from the LGA4189-5 “Cedar Island” used in Cooper Lake, the two are not interoperable, but they do have the same power distribution.

This actually made us understand Intel’s product portfolio.Technically speaking, 10nm ice lake is not the only member of 3rd Gen Xeon Scalable Series-Intel thinks it is appropriate to bundle 14nm Cooper Lake and 10nm Ice Lake under the same title. Intel focused Cooper Lake on a few specific high-volume customers who wish to deploy four-way and eight-way systems with specific AI workloads, thereby separating the two. In contrast, Ice Lake is for the mass market and is limited to two socket systems.

The processor names of Ice Lake and Cooper Lake have a “3”, which means the third generation. The user can tell which is Cooper Lake because they end in H or HL-Ice Lake processors (we will see on the next page) will never have H or HL. In any case, most Cooper Lake processors are Platinum models, and some Xeon Gold. When conducting this review, we will only focus on Ice Lake, because this is the platform that Intel sells to the mainstream.

This review

Before today’s release, Intel provided us with a 2U system that contains two top models of Ice Lake Xeon: We have dual 40-core Xeon Platinum 8380s! At the same time, we also spent some time purchasing a dual Xeon Gold 6330 system from Supermicro, which has two 28-core processors, which can be compared well with the previous generation Xeon Platinum 8280.

Today our review will cover the processor stack, benchmarking, power analysis, memory analysis and some preliminary conclusions.
