Back in September 2021, reports about Intel working on something called SDSi or software defined silicon, started to appear. Now, over a year later, the company has finally launched its SDSi products under the Intel On Demand branding. Back then, we speculated about what features Intel would put behind a paywall and although we were somewhat off track, Intel has put some specific "instructions" behind the paywall on the supported Xeon processors. Specifically, some CPUs will have Quick Assist, Dynamic Load Balancer and Data Streaming Accelerator available as an On Demand feature. Additionally, Intel is also putting its Software Guard Extensions and In-Memory Analytics Accelerator behind the same pay wall.

It appears that these features will be offered as-a-service offering from some of Intel's service partners, but there's also a "one-time activation of select CPU accelerators and security features" according to the Intel On Demand website. It's unclear which Xeon SKUs will get Intel On Demand, but according to The Register, it'll be the upcoming Sapphire Rapids based Xeon processors which should be the first parts affected. Intel has listed partners like HP, Lenovo and SuperMicro, among others, that are involved with the Intel On Demand program. It will still be possible to buy next gen Xeon CPUs that are fully feature enabled like today, but it's unclear if the Intel On Demand Xeon SKUs will offer some kind of cost benefits to companies that don't need the additional features that are behind the paywall.

Supermicro, Inc., a Total IT Solution Provider for Cloud, AI/ML, Storage, and 5G/Edge, at the 2022 Super Computing Conference is unveiling the most extensive portfolio of servers and storage systems in the industry based on the upcoming 4th Gen Intel Xeon Scalable processor, formerly codenamed Sapphire Rapids. Supermicro continues to use its Building Block Solutions approach to deliver state-of-the-art and secure systems for the most demanding AI, Cloud, and 5G Edge requirements. The systems support high-performance CPUs and DDR5 memory with up to 2X the performance and capacities up to 512 GB DIMMs and PCIe 5.0, which doubles I/O bandwidth. Intel Xeon CPU Max Series CPUs (formerly codenamed Sapphire Rapids HBM High Bandwidth Memory (HBM)) is also available on a range of Supermicro X13 systems. In addition, support for high ambient temperature environments at up to 40° C (104° F), with servers designed for air and liquid cooling for optimal efficiency, are rack-scale optimized with open industry standard designs and improved security and manageability.

"Supermicro is once again at the forefront of delivering the broadest portfolio of systems based on the latest technology from Intel," stated Charles Liang, president and CEO of Supermicro. "Our Total IT Solutions strategy enables us to deliver a complete solution to our customers, which includes hardware, software, rack-scale testing, and liquid cooling. Our innovative platform design and architecture bring the best from the 4th Gen Intel Xeon Scalable processors, delivering maximum performance, configurability, and power savings to tackle the growing demand for performance and energy efficiency. The systems are rack-scale optimized with Supermicro's significant growth of rack-scale manufacturing of up to 3X rack capacity."

Intel has just released its "Architecture Instruction Set Extensions and Future Features Programming Reference" manual, which serves the purpose of providing the developers' information about Intel's upcoming hardware additions which developers can utilize later on. Today, thanks to the @InstLatX64 on Twitter we have information that Intel is bringing on-package High Bandwidth Memory (HBM) solution to its next-generation Sapphire Rapids Xeon processors. Specifically, there are two instructions mentioned: 0220H - HBM command/address parity error and 0221H - HBM data parity error. Both instructions are there to address data errors in HBM so the CPU operates with correct data.

The addition of HBM is just one of the many new technologies Sapphire Rapids brings. The platform is supposedly going to bring many new technologies like an eight-channel DDR5 memory controller enriched with Intel's Data Streaming Accelerator (DSA). To connect to all of the external accelerators, the platform uses PCIe 5.0 protocol paired with CXL 1.1 standard to enable cache coherency in the system. And as a reminder, this would not be the first time we see a server CPU use HBM. Fujitsu has developed an A64FX processor with 48 cores and HBM memory, and it is powering today's most powerful supercomputer - Fugaku. That is showing how much can a processor get improved by adding a faster memory on-board. We are waiting to see how Intel manages to play it out and what we end up seeing on the market when Sapphire Rapids is delivered.

Today, thanks to the ServeTheHome forum member "111alan", we have the first pictures of the alleged Intel Sapphire Rapids Xeon processor. Pictured is what appears to be a dual-die design similar to Cascade Lake-SP design with 56 cores and 112 threads that uses two dies. The Sapphire Rapids is a 10 nm SuperFin design that allegedly comes even in the dual-die configuration. To host this processor, the motherboard needs an LGA4677 socket with 4677 pins present. The new LGA socket, along with the new 10 nm Sapphire Rapids Xeon processors are set for delivery in 2021 when Intel is expected to launch its new processors and their respective platforms.

The processor pictured is clearly a dual-die design, meaning that Intel used some of its Multi-Chip Package (MCM) technology that uses EMIB to interconnect the silicon using an active interposer. As a reminder, the new 10 nm Sapphire Rapids platform is supposed to bring many new features like a DDR5 memory controller paired with Intel's Data Streaming Accelerator (DSA); a brand new PCIe 5.0 standard protocol with a 32 GT/s data transfer rate, and a CXL 1.1 support for next-generation accelerators. The exact configuration of this processor is unknown, however, it is an engineering sample with a clock frequency of a modest 2.0 GHz.

Intel has today launched a new product called Data Streaming Accelerator known as Intel DSA shortly. The new device is going to be present inside every future Intel processor with a goal of "optimizing streaming data movement and transformation operations common with applications for high-performance storage, networking, persistent memory, and various data processing applications."

The DSA processor will replace an existing solution that is Intel QuickData Technology, which was previously used for data movement. This new dedicated processor has a much-needed purpose to free up CPU cycles from doing IO work like moving data to/from volatile memory, persistent memory, memory-mapped I/O, and through a Non-Transparent Bridge (NTB) device to/from remote volatile and persistent memory inside a chip. In addition to the usual data movement operations, the DSA processor can create and test CRC checksums for any errors in storage and networking applications.
