Apple’s M1 Ultra Shows the Future of Computer Chips

March 14, 2022 Audrey

Apple’s M1 Mac processor family began with the M1 in 2020 and expanded — literally — with the M1 Pro, M1 Max and M1 Ultra. The M1 Ultra is made of two M1 Max chips.

If you want a glimpse of where the processor business is headed, check out Apple’s new M1 Ultra processor.

To deliver speed and performance, the consumer electronics giant married two of its older M1 Max chips using advancements in a once humble aspect of chipmaking called packaging. Packaging no longer just provides a protective housing but now also offers cutting-edge communication links.

By combining the two chips, Apple’s M1 Ultra delivers a stunning 114 billion transistors that make up 20 processing cores and 64 graphics cores. By comparison, AMD Ryzen desktop processors use something like a tenth that number of transistors.

The M1 Ultra highlights the progress chipmakers have achieved in keeping Moore’s Law alive. A dictum in the chip industry, Moore’s Law predicts that the number of transistors on chips doubles every two years. Transistors, the basic circuit elements that process data, have been harder to miniaturize, which has slowed the progress initially charted by chip pioneer and Intel co-founder Gordon Moore. Advanced packaging offers a new way to bump up those transistor counts.

Apple isn’t the only company working on advanced packaging technology to link chips together. Intel, AMD and Nvidia also have technology to combine multiple chip elements, called dies or chiplets, into a single larger processor. The M1 Ultra is arguably the most advanced example of the concept so far, but it won’t be the last.

“You’ll see it in mainstream PCs over time,” said Tech Insights analyst Linley Gwennap, not just the Mac Studio systems costing $4,000 and up.

Chip packaging advances

Packaging has been around for as long as chips have been. Initially, it involved a housing to protect a processor and provide it with the electrical links to memory, communications and other elements of a computer. Over the years, it’s gotten more and more complex. Now chipmakers see advanced packaging as a crucial element in sustaining computing progress.

Apple’s UltraFusion, the name of its packaging technology, uses a narrow silicon slice called an interposer that resides beneath the two M1 Max chips, linking them with 10,000 wires that can carry 2.5 terabytes of data per second over a very short distance. That enormous speed is necessary so chip cores on one die can reach memory that’s connected to the other. Graphics processing units in particular have an insatiable appetite for data stored in memory.

Interposers historically have been large and expensive. Apple’s custom approach involves a narrower slice that only traverses the connecting edges of the M1 Max chips.

Intel has developed a similar packaging technology, which it calls Embedded Multi-Die Interconnect Bridge. Intel hasn’t used EMIB in any chips that are on the market

GM states Qualcomm’s computer system chips will electricity its next-gen ‘hands-free’ driving method

January 9, 2022 Audrey

Basic Motors wholly redesigned the compute architecture that powers its upcoming-era “hands-free” driving method many thanks to US semiconductor business Qualcomm.

The automaker’s Extremely Cruise method, which will make its debut in the 2024 Cadillac Celestiq electrical sedan, will be the to start with state-of-the-art driver guide program (ADAS) to use Qualcomm’s new Snapdragon Experience System. The dimensions of “two laptops stacked collectively,” GM statements the new architecture will have the processing electricity equal to “several hundred” private desktops.

GM very first declared Ultra Cruise through an investor function previous year, describing it as a significant leap in excess of the company’s Tremendous Cruise program, which permits for palms-free driving on mapped, divided highways. In distinction, Extremely Cruise will include “95 percent” of driving situations on 2 million miles of roadways in the US, the corporation claimed.

“We’re making an attempt to have this aspect be kind of a door-to-door driverless operation,” reported Jason Ditman, chief engineer at GM, in an job interview with The Verge. “When the car gets on to a able highway, Extremely Cruise will immediately interact and handle the vast majority of the operate, palms-absolutely free. Stop signals, stoplights, turns, splits, merges, freeways, subdivision… all of those domains.”

That is many thanks to Qualcomm’s new higher-driven processors, Ditman said. Final calendar year, Qualcomm entered into an settlement with GM to provide laptop or computer chips for the automaker’s upcoming era of electric powered vehicles. When it comes out in 2023, the Cadillac Celestiq will be just one of the to start with automobiles to aspect the chipmaker’s new ADAS platform, which incorporates Qualcomm’s Snapdragon SA8540P program-on-a-chip and SA9000P synthetic intelligence accelerator.

People two SoCs will produce “low-latency management capabilities on 16-core CPUs and higher-efficiency AI compute of additional than 300 Tera Functions For each 2nd for digicam, radar, and lidar processing,” GM suggests. But much more importantly, it saves the automaker a large amount of area.

“It lets us be serious productive with area,” Ditman mentioned. “It presents us the throughput that we require. And it let us get what was initially architected to be distributed modules during the automobile and transfer all that features into the 1 box.”

Consolidating modules for driver monitoring, mapping, and video clip processing into one particular box has also enhanced the system’s latency, Ditman stated, because it allows GM to bypass the earlier process routed through the vehicle’s CAN network. Ultra Cruise will use sensors like cameras, radars, and lidar to manage the vehicle’s steering, acceleration, and braking. GM hasn’t declared all the particulars all around the sensor suite, but Ditman noted that the technique depends on a complete of 20 diverse equipment.

Despite its improved capabilities, GM claims it still considers Extremely Cruise a Level 2 technique, as outlined by the Modern society of Automotive Engineers. At Stage 2, the car or truck can management both of those steering and acceleration and deceleration, as very well

Does Tesla’s Centralized Pc Architecture Call for Fewer Chips?

Of all the improvements Tesla has introduced to the car market, not the minimum sizeable is the unified personal computer architecture utilised in its cars. This has enabled numerous of the fantastic Tesla-only functions that house owners rave about, and it is not way too substantially to say that it is been just one of the company’s greatest aggressive advantages. Now existing events are highlighting what could be another big profit.

When researching my reserve, Tesla: How Elon Musk and Company Designed Electric Automobiles Cool, and Remade the Automotive and Electricity Industries, I was privileged to be equipped to interview Tesla co-founder Ian Wright, who offered some keen insights about Tesla’s devices strategy to its software program, and this turned out to be 1 of my favourite pieces of the e book. I have referred to it in at the very least a dozen article content, and many thanks to the ongoing semiconductor shortage, it seems like I’m likely to get some more mileage out of it.

The younger Tesla experienced roots in the Silicon Valley tech sector, and its autos ended up made with a single computer operating technique from the starting. This was the reverse of the way the legacy automakers had been (and primarily nevertheless are) undertaking matters. A common legacy car or truck has a patchwork of separate personal computers that control distinctive systems in the auto. “I’m searching out the window at my 2008 Volkswagen Touareg, and I wager that’s got sixty or seventy digital black containers, 3 hundred lbs of wiring harness, and program from twenty various firms in it,” Ian Wright explained to me in 2014.

Consultancy Roland Berger recently told Bloomberg that automakers have to have to redesign cars to use less semiconductors. Automakers are hoping that the hated chip lack will wind down before long, but Roland Berger predicts that intense bottlenecks will persist by means of 2022.

“Carmakers need to speed up the changeover to centralized electronic architectures and thereby transfer to advanced and top-edge nodes,” the analysts mentioned in a modern report. A shift to a central style with a solitary onboard laptop could considerably minimize the quantity of chips wanted in a automobile. Roland Berger claims the typical automobile contains some 1,400 individual chips.

Certainly, visitors, my interview with Ian Wright took location seven decades in the past. He informed me that the legacy automakers ended up “struggling” with the program structure in their automobiles, and that
