The team ran Intel’s latest 16-core Sapphire Rapids Xeon CPU on an ASRock W790 motherboard, initially clocked at 6.1GHz, and scored 46,000 points on Cinebench R23.

Note: All 16 cores on the Sapphire Rapids Xeon CPU are performance cores, based on the same Golden Cove specification as Intel’s 12th Generation Alder Lake desktop CPUs.

The team then overclocked it to 7.2GHz, but the system was too unstable to complete any benchmark runs at that frequency.

Geekbench information shows that the Intel Xeon W9-3495X has 56 CPU cores with a base frequency of 1.9 GHz and a maximum frequency of 4.6 GHz. In addition, the processor has 105MB of L3 cache and 56MB of L2 cache.

The running score shows that the processor is equipped with 128GB DDR5-4800 memory + Supermicro X13SWA-TF motherboard, with a single-core running score of 1284 and a multi-core running score of 36990. Single-core performance is about 15% lower than AMD’s flagship workstation processor, the Threadripper PRO 5995WX, and multi-core performance is also weaker (the latter can reach 40,000 points).

In addition, industry sources said that Intel will ramp up (ramp-up) Sapphire Rapids production in May. It is said that Intel’s official release time is January 10, but only a small number of samples are expected to be available in the initial stage.

Currently, Samsung Electronics has developed 16Gb DDR5 DRAM using a 12nm-class process, and SK Hynix has developed ultra-high-speed DDR5 DRAM for servers, but it is only being used for certain testing purposes because there are no DDR5-enabled CPUs that can be properly supplied by next-generation data centers.

Park Jae-geun, president of the Korea Semiconductor Display Technology Society (a professor at Hanyang University), said, “Actual DDR5 DRAM sales may not be possible until the third or fourth quarter if data center companies perform field validation work.”

The Sapphire Rapids-WS processors may be called the Xeon W 3400 series when they become available. These processors will use Intel’s new W790 platform, offering up to 56 cores, 8 DDR5 memory lanes and 112 PCIe lanes. In addition, these CPUs will be based on high-performance Golden Cove-derived cores with AVX-512 and AMX instructions enabled.

In the warm-up video, a woman said: “This chip is too powerful! The task that used to be done with a room-sized computer can be completed in just 30 minutes of coffee time with this processor. The first few days I said at the meeting the other day that the final test run turned out to be very good and the time to results was very short.”

The Sapphire Rapids-WS processor may be called the Xeon W 3400 series after it goes on the market. The processors will use Intel’s new W790 platform, offering up to 56 cores, 8 channels of DDR5 memory, and 112 lanes of PCIe. Additionally, these CPUs will be based on high-performance Golden Cove-derived cores, enabling AVX-512 and AMX instructions.

According to Wccftech, the Intel Sapphire Rapids-WS and W790 platforms will be released in the seventh week of 2023 (sometime between February 12 and February 18) and will be available in April. This will be a major upgrade after the Ice Lake-SP series, comparing the latter with a maximum number of only 38 cores.

The new product, codenamed “Fishhawk Falls”, will reportedly feature a Quad Die tiled design with up to 56 physical cores.

Looking at Intel’s roadmap, the new generation of Xeon is divided into multiple product lines just like the Core series, such as Xeon W9, Xeon W7, Xeon W5 and Xeon W3. Each market segment has its own product needs.

As for the CPU family itself, the Intel Xeon W9 series will include 56-core and 36-core models with 105MB of cache, 350W TDP and 112 PCIe Gen 5.0 lanes.

In addition, the Xeon W5 series includes 28-, 24- and 20-core models with 75 MB of cache and 300W TDP, while the Xeon W3 class processors are only available in 16- and 12-core SKUs, along with 45 MB of cache and 270W TDP.

According to a report released by TrendForce on November 1, the mass production schedule of the new Sapphire Rapids has been postponed due to Intel’s poor 7nm yield, and the current production yield of Sapphire Rapids is expected to be only 50%-60%. The mass production schedule was postponed from the fourth quarter of this year to the first half of 2023.

The Sapphire Rapids will be officially released on January 11 2023, Intel confirmed. The Sapphire Rapids will support PCIe Gen5 and DDR5 technology.

In addition, Sapphire Rapids will also be compatible with the successor product called “Emerald Rapids” launched in the same year, the new CPU will provide up to 60 cores based on the “Golden Cove” architecture. The new CPUs will offer up to 60 cores based on the “Golden Cove” architecture.

Intel’s upcoming fourth-generation Xeon Scalable processor code-named Sapphire Rapids, manufactured by Intel 7 process, up to 60 cores, actually enabled 56 cores, TDP power consumption is said to be increased from the previous 270W to 350W, but this is still basic, It is not impossible to actually exceed 400W.

Such high power consumption can no longer be used with traditional air cooling. It is not only the noise problem, but also the energy efficiency can not keep up, and the energy efficiency problem directly affects the operating cost of the data center, so Intel announced earlier this year to invest 7 billion of dollars to develop a new way of water cooling (more accurately it should be liquid cooling).

At the recent innovation conference, Intel also disclosed some of the water cooling systems and will launch a variety of public water cooling solutions for the Sapphire Rapids processor.

According to the information released by Intel, this water cooling solution has multiple usage scenarios, from servers to modules to racks and cabinets, there are corresponding solutions, of which the cooling capacity can already reach 15KW, that is, the level of 15000W. Even if it is a 300-400W CPU/GPU, it is estimated that a set of 30+ chips will be no problem.

This cooling system is still under development and optimization and has been adopted by many manufacturers. Inspur, a domestic server manufacturer, has demonstrated such a server. When the Sapphire Rapids processor is fully launched in the future, it is estimated that more manufacturers will follow.

Igor’s Lab recently pointed out that Intel has delayed the general availability of Sapphire Rapids-SP to early February-early March 2023.

In addition, the family of enterprise processors is said to have up to 12 steps — in addition to the newly discovered E5, there are versions of A0, A1, B0, C0, C1, C2, D0, E0, E2, E3 and E4.

Presumably, Intel sent samples of Sapphire Rapids-SP for validation to various large customers to help them evaluate the performance of these chips in various application scenarios.

Finally, Sapphire Rapids is built on the “Intel 7” process node with up to 60 Golden Cove high-performance CPU cores, DDR5 memory I/O and PCIe 5.0 support, complemented by a variety of on-chip gas pedal IP.

VideoCardz points out that the W790 chipset’s Q-Spec designation is also SRL02, and that the step has reached B1, in line with the current 600 series of consumer motherboards.

However, in this document, Intel is also confirming the existence of this W790 chipset for the first time. Even though the HEDT platform is not yet listed for those CPU SKUs that will be supported, this is not the first time we hear its name.

Documentation (from: Intel official website)

As early as last year, it was announced that the W790 would underpin the Sapphire Rapids HEDT platform. The Sapphire Rapids-X, as it is often called, is the successor to the long-unrefreshed Glacier Falls and Cascade Lake-X CPUs.

"By shifting the naming architecture from X-series chipsets to W-series chipsets, Intel is sort of indicating that these systems will be designed for workstations, not just desktop enthusiasts.

Similar to AMD's non-Pro 'Threadripper' line, the real Core-X series is probably already buried in the dirt."

It was originally rumored that the W790 motherboard was expected to launch in Q4 2022 with the 13th generation Raptor Lake desktop CPU product line.

Unfortunately, the Sapphire Rapids-SP data center processor issue may have forced the legendary Sapphire Rapids-X series to be delayed as well.

Last month, the HWiNFO hardware monitoring tool mentioned in the changelog an ASUS Pro WS W790E-SAEG motherboard, which is known to be a product line designed for server/workstation systems.

However, it has been a long time since the chip giant has updated the product line since Intel’s second generation Xeon Scalable CPU (205W) and C621 chipset.

In terms of specifications, the W790 motherboard will not only support DDR5 memory and PCIe 5.0 interface, but may also support Intel Sapphire Rapids-X CPUs with up to 350W TDP.
