The Sapphire Rapids chip was seen in the real world; Does Intel make a chip with two separate Die?

A member of the online community ServeTheHome posted pictures a few days ago that apparently belong to the new series processors They are Intel Xeon Scalable called Sapphire Rapids. If the leaked images are real, they indicate that the Rapids Sapphire series chips are supposed to see some design differences.

As can be seen from the pictures, Intel has decided to use two dyes in the Sapphire Rapids family instead of a single die. The images released on ServeTheHome show a processor with an LGA socket that uses a metal heat exchanger and bears the phrase “Intel Confidential”. The use of the term Intel Confidential indicates that the chip in question is the final chip pre-production model and was made solely for the purpose of performing certain tests and evaluating the conditions.

Another expression seen on the chip surface indicates that the new Xeon Scalable series processor has a clock speed of approximately 2 GHz; This clock speed is exactly what we expect from a processor prototype.

Since the Sapphire Rapids processor is currently in pre-production, it has a four-letter model number: QTQ2. The processor in question does not look like a regular Intel processor, which is why most analysts say the leaked images belong to Sapphire Rapids series processors, which have a new design.

The front of the Intel Sapphire Rapids chip has been revealed

On the front of this Intel chip, we see some details that may be a little deceptive at first glance. The CPU heat dissipator has two almost equal protrusions. The heat dissipating screen in today’s Intel processors has a series of protrusions; But one of them is always known as the main protrusion and is bigger than the others. This bulge is located just above the main processor die.

Two bumps of the same size may mean that Intel intends to use two dials for Sapphire Rapids series processors; Processors, on the other hand, typically have an integrated die.

The back of the Intel Sapphire Rapids chip has been revealed

The back of the unannounced Intel processor is very similar to other processors that the Blue Team builds for server use. In this image we see that, as always, the network array behind the CPU is divided into two equal parts. In addition, two very similar sets of capacitors can be seen in the middle part of the processor. The use of capacitors with this type of design makes it possible to benefit from series processors Sapphire Rapids from MCM Designا(Multi-Chip Module – High) This has been mentioned in other reports before.

Sapphire Rapids seems to rely on the design of a Multi-Chip Module with two separate dials, and the dials are connected through one of Intel’s new technologies such as EMIB. On the back of Intel integrated processors, you can see only a set of capacitors.

The dual protrusion of the front of the processor indicates the possibility of making it with MCM design

Using MCM design, also known as chiplet design, has some important advantages for chipmakers in developing and manufacturing. For obvious reasons, chips with smaller dimensions are easier to design, manufacture, and debug. In addition, smaller chips are easier than other chips to achieve good clock speeds and good performance.

Large integrated chips, on the other hand, are more efficient; Because integrated chips use internal communication systems; But the design of the chiplet comes with external communication systems to connect the nannies to each other. Experts say internal communication systems are always faster than external systems.

Intel never commented on the information leaked from its chips, and this time it does not intend to react to leaked images attributed to Sapphire Rapids. So do not expect the Blue Team to confirm or deny the leaked details of Sapphire Rapids any time soon.

Intel has officially announced that Sapphire Rapids series processors will use cores based on the Golden Cove microarchitecture; These cores have the ability to support AMX capabilityا(Advanced Matrix Extensions) have Intel and support the AVX512_BF16 and AVX512_VP2INTERSECT instructions. The two guidelines in question are very useful for data center and supercomputer tasks.

Earlier unofficial reports said that the Sapphire Rapids series processors support DDR5 and PCIe 5.0 standards, have a power output of up to 400 watts, and have 56 processing cores. Intel will produce the Rapids Sapphire series chips based on an improved version of SuperFin 10nm lithography.
