What is Intel Ice Lake?

Ice Lake is the name given to the 10th generation datacentre CPU from Intel. In fact, Ice Lake also refers to the third-generation Intel Xeon Scalable processor. The codename is used for the 10th generation Intel Core mobile and 3rd generation Xeon Scalable server processors based on the new Sunny Cove microarchitecture.

Ice lake is the second-generation microarchitecture to be used in the 10 nm manufacturing process. It is also called the 10 nm+ processes to indicate that this is the second-generation 10 nm manufacturing process, also called 10nm+. Some of the integrated features put Intel’s offerings over AMD’s. They are as follows:

  • AVX-512
  • DLBoost
  • Hardware cryptography acceleration (ISA, allowing AES, SHA, GFNI)
  • Better security
  • Optane 200 DC Persistent Memory
  • Agilex FPGAs
  • SmartNICs &
  • 800-series Ethernet

Intel’s Sunny Cove core has actually previously been in the market. Intel has made a consumer alternative of the core and a server variant of the core. Ice Lake Xeon has the server alternative, with bigger, integrated caches and imperceptibly different optimization cases, but it’s the consumer variant that we have examined and experimented with in laptop form. Sunny Cove is indeed a part of Intel’s Ice Lake notebook CPU portfolio.

The Ice Lake processors have been one of the excellent options for high-end laptops, and that should perhaps explain why they are a much-preferred option for the manufacturers. Dell XPS 13 2 in 1 was probably the first laptop with the Intel Ice Lake processor.

The prime feature of the Intl Ice Lake processor is the 10nm Sunny Cove architecture. They are also known for the first chip to feature the next-generation Gen11 graphics on consumer parts. That apart, there are several advantages and benefits offered by Intel Ice Lake processor.

The new processors are believed to be delivering a 2x performance increase. You will also get access to great native support for Thunderbolt 3, Wi-Fi 6 (802.11ax), and DL Boost. Even the graphics are pretty impressive. The new processor comes with 64 EUs or Executive Units. The boost speeds tend to be a little on the lower side. Now, that’s the consumer part of the story.

Now, on the server parts, here are some of the top advantages:

  • 70% – 80% more cache
  • PCIe Gen4
  • 43% more cores on the top-end
  • 64 PCIe lanes over 48
  • 4x max memory support
  • 7% more interconnect bandwidth
  • 8 channels of DDR4-3200 at 2DPC (Only high-end parts)
  • Native support for DDR4 – 3200
  • It is cheaper than its predecessors.

The Best Intel C621A Chipset Ice Lake Motherboards:

With the new Xeon chips, we have the LGA4189 socket. You may hear references to Socket P4, Socket P5, Socket P+, LGA4189-4, LGA4189-5, and more names. From the installation perspective, or to install CPU coolers, these all use the same cooler mounting. The LGA4189 CPUs are more significant than the LGA3647 parts that preceded them. The width is very close, but one can see they are slightly longer.

Difference between 14nm Cooper Lake and 10nm Ice Lake:

Important Note: Ice Lake Xeons, which now comes with eight memory channels rather than six, will require a new socket and a new set of motherboards. These Ice Lake parts come with 4189 pins and require an LGA4189-4 ‘Whitley’ motherboard spec. This is distinct from the LGA4189-5 ‘Cedar Island’ that is already in use for Cooper Lake, and the two are not interoperable, however, they do share a common power profile.

Both the 14nm Cooper Lake and 10nm Ice Lake come under the same product portfolio. Intel is dividing the two by stating that Cooper Lake is more focused on several specific high-volume customers looking to deploy quad-socket and eight-socket high-density server systems with specific deep learning or AI workloads. By comparison, Ice Lake is for the mass market consumers and is limited to only two-socket systems.

Having checked out Intel Ice Lake processors’ primary features and specifications, how about checking out the best motherboards that can be used with your Intel Lake motherboards? We will check a few of the excellent options that can prove to be practical enough.

Close on the heels of the Ice Lake-SP 3rd Generation Xeon Scalable processor launch announcement, several manufacturers have been involved in offering the best Intel Ice Lake Motherboards. Gigabyte has been an excellent option for almost all your expectations.

What is so special about the Intel Ice Lake Processors?

The prime factor that would make the Intel Ice Lake processor one of the most promising options is that it comes with the path-breaking 10 nm manufacturing process. The ability to have as many as eight memory channels should be akin to making it a formidable choice for memory-intensive workloads.

The processor moves to a complete PCIe 4.0 technology. In addition to that, you can also expect a 2X bandwidth increase on the PCIe Gen 4.0 architecture. Built-in acceleration and security have been a few of the excellent options for achieving the best standards ever. Ice lake processors are designed to provide you up to 56 percent more AI performance. You will also find it offering a 66 percent boost in terms of image recognition.

The SKU stack can be yet another excellent option for most of the expectations you may have. The Ice Lake family of the processors comes with 56 SKUs. They are classified into ten segments with the highest per-core scalable performance, scalable performance, and single socket optimized parts. You would also find the SKUs optimized for cloud, networking, media, and other workloads.

The Final Words

Well, the Intel Ice Lake processors have been quite promising in every respect. However, many motherboard manufacturers are working on offering the best motherboards for the Intel Ice Lake processors. We found none of the popular motherboard manufacturers except for Gigabyte seem interested in providing the specific motherboard for the purpose.

Check out the best options offered to you from Gigabyte and Axiomtek and get access to a greater degree of performance for most of your expectations.
