Intel's CEO Role Could be Filled by Former Board Member Lip-Bu Tan

The search for a new Chief Executive Officer (CEO) of Intel has begun following Pat Gelsinger's departure on Monday. And it is not exactly an easy role to be filled. The tech giant's board is primarily considering external candidates to lead the company through one of its most challenging periods. Among the potential successors is Lip-Bu Tan, a former Intel board member and semiconductor industry veteran. Tan, who previously served as CEO of Cadence Design, left Intel's board in August 2023 after disagreements with Gelsinger over the company's strategic direction. Despite these past tensions, Intel's board has reportedly recently approached Tan to gauge his interest in the position. The search for new leadership is extremely difficult, considering the requirements and massive problems the new CEO would face.

Coming at a critical moment for Intel, which has experienced significant financial challenges under Gelsinger's tenure, the new CEO would need to get the Foundry business to pick up and maintain a solid product roadmap. The company's revenue dropped to $54 billion in 2023, marking a nearly one-third decline since Gelsinger took the helm in 2021. Analysts project Intel's first annual net loss since 1986 this year, with long-term signs of recovery. Gelsinger's exit, which came after the board presented him with the option to retire or be removed, reflects growing impatience with the pace of his ambitious turnaround strategy. The company has appointed CFO David Zinsner and senior executive Michelle Johnston Holthaus as interim co-CEOs while the search committee works to identify a permanent replacement.

We expect these actions to meaningfully improve liquidity and reduce our debt balance while enabling us to make the right investments to drive long-term value for shareholders."

TSMC Unveils Next-Generation HBM4 Base Dies, Built on 12 nm and 5 nm Nodes

During the European Technology Symposium 2024, TSMC has announced its readiness to manufacture next-generation HBM4 base dies using both 12 nm and 5 nm nodes. This significant development is expected to substantially improve the performance, power consumption, and logic density of HBM4 memory, catering to the demands of high-performance computing (HPC) and artificial intelligence (AI) applications. The shift from a traditional 1024-bit interface to an ultra-wide 2048-bit interface is a key aspect of the new HBM4 standard. This change will enable the integration of more logic and higher performance while reducing power consumption. TSMC's N12FFC+ and N5 processes will be used to produce these base dies, with the N12FFC+ process offering a cost-effective solution for achieving HBM4 performance and the N5 process providing even more logic and lower power consumption at HBM4 speeds.

The company is collaborating with major HBM memory partners, including Micron, Samsung, and SK Hynix, to integrate advanced nodes for HBM4 full-stack integration. TSMC's base die, fabricated using the N12FFC+ process, will be used to install HBM4 memory stacks on a silicon interposer alongside system-on-chips (SoCs). This setup will enable the creation of 12-Hi (48 GB) and 16-Hi (64 GB) stacks with per-stack bandwidth exceeding 2 TB/s. TSMC's collaboration with EDA partners like Cadence, Synopsys, and Ansys ensures the integrity of HBM4 channel signals, thermal accuracy, and electromagnetic interference (EMI) in the new HBM4 base dies. TSMC is also optimizing CoWoS-L and CoWoS-R for HBM4 integration, meaning that massive high-performance chips are already utilizing this technology and getting ready for volume manufacturing.

Arm Prepares for IPO: Apple, NVIDIA, Intel, and Samsung are Strategic Partners

Arm's impending IPO, valued between $60 billion and $70 billion, has reportedly garnered substantial backing from industry giants such as Apple, NVIDIA, Intel, and Samsung, as per sources cited in a Bloomberg report. This much-anticipated public offering serves as a litmus test for investor interest in new chip-related stocks and could reshape the tech industry landscape. While the information remains unofficial, it underscores the significant support Arm has received from major licensees, including Apple, AMD, Cadence, Intel, Google, NVIDIA, Samsung, and Synopsys, with each potentially contributing between $25 million and $100 million, a testament to their confidence in Arm's future prospects. Originally, SoftBank aimed to raise $8 billion to $10 billion through the IPO, but a strategic shift to retain a larger Arm stake revised the target to $5 billion to $7 billion.

This IPO's success holds paramount importance for SoftBank and its CEO, Masayoshi Son, particularly following the Vision Fund's substantial $30 billion loss in the previous fiscal year. Masayoshi Son is reportedly committed to maintaining significant control over Arm, planning to release no more than 10% of the company's shares during this initial phase, aligning with SoftBank's recent acquisition of the Vision Fund's Arm stake and reinforcing their belief in Arm's long-term potential. Arm has enlisted renowned global financial institutions such as Barclays, Goldman Sachs Group, JPMorgan Chase & Co., and Mizuho Financial Group to prepare for the IPO, highlighting the widespread interest in the offering and the anticipated benefits for these financial institutions.

Micron Readying GDDR7 Memory for 2024

Last week Micron Technology CEO, Sanjay Mehrotra, announced during an investors meeting that the company's next generation GPU memory—GDDR7—will be arriving next year: "In graphics, industry analysts continue to expect graphics' TAM compound annual growth rate (CAGR) to outpace the broader market, supported by applications across client and data center. We expect customer inventories to normalize in calendar Q3. We plan to introduce our next-generation G7 product on our industry-leading 1ß node in the first half of calendar year 2024." His proposed launch window seems to align with information gleaned from previous reports—with NVIDIA and AMD lined up to fit GDDR7 SGRAM onto their next-gen mainstream GPUs, although Team Green could be delaying their Ada Lovelace successor into 2025.

Micron already counts these big players as key clients for its current GDDR6 and GDDR6X video memory offerings, but Samsung could be vying for some of that action with its own GDDR7 technology (as announced late last year). Presentation material indicated that Samsung is anticipating data transfer rates in the range of 36 Gbps, with usage of PAM3 signalling. Cadence has also confirmed similar numbers for its (industry first) GDDR7 verification solution, but the different encoding standard will require revising of memory controllers and physical interfaces.

Huawei Reportedly Develops Chip Design Tools for 14 nm and Above

Amid the US sanctions, Chinese technology giant Huawei has reportedly developed tools to create processors with 14 nm and above lithography. According to Chinese media Yicai, Huawei and its semiconductor partners have teamed up to create replacement tools in place of US chip toolmakers like Cadence, Synopsys, and Mentor/Siemens. These three companies control all of the world's Electronic Design Automation (EDA) tools used for every step of chip design, from architecture to placement and routing to the final physical layout. Many steps need to be taken before making a tapeout of a physical chip, and Huawei's newly developed EDA tools will help the Chinese industry with US sanctions which crippled Huawei for a long time.

Having no access to US-made chipmaking tools, Huawei has invested substantial time into making these EDA tools. However, with competing EDA makers supporting lithography way below 14 nm, Huawei's job still needs to be completed. Chinese semiconductor factories are currently capable of 7 nm chip production, and Huawei itself is working on making a sub-7 nm EUV scanner to aid manufacturing goals and compete with the latest from TSMC and other. If Huawei can create EUV scanners that can achieve transistor sizes smaller than 7 nm, we expect to see their EDA tools keep pace as well. It is only a matter of time before they announce adaptation for smaller nodes.

NVIDIA GeForce RTX 50-series and AMD RDNA4 Radeon RX 8000 to Debut GDDR7 Memory

With Samsung Electronics announcing that the next-generation GDDR7 memory standard is in development, and Cadence, a vital IP provider for DRAM PHY, EDA software, and validation tools announcing its latest validation solution, the decks are clear for the new memory standard to debut with the next-generation of GPUs. GDDR7 would succeed GDDR6, which had debuted in 2018, and has been around for nearly 5 years now. GDDR6 launched with speeds of 14 Gbps, and its derivatives are now in production with speeds as high as 24 Gbps. It provided a generational doubling in speeds from the preceding GDDR5.

The new GDDR7 promises the same, with its starting speeds said to be as high as 36 Gbps, going beyond the 50 Gbps mark in its lifecycle. A MyDrivers report says that NVIDIA's next-generation GeForce RTX 50-series, probably slated for a late-2024 debut, as well as AMD's competing RDNA4 graphics architecture, could introduce GDDR7 at its starting speeds of 36 Gbps. A GPU with a 256-bit wide GDDR7 interface would enjoy 1.15 TB/s of bandwidth, and one with 384-bit would have a cool 1.7 TB/s to play with. We still don't know what is the codename of NVIDIA's next graphics architecture, it could be any of the ones NVIDIA hasn't used from the image below.

Cadence Announces The First GDDR7 Verification Solution

Cadence, a leading developer of tools for system design and verification, has announced the industry's first GDDR7 verification solution. This in-depth software solution affords IC designers the ability to simulate and verify their GDDR7 silicon designs before printing a single chip. The challenges of designing GDDR7 stem from a rather massive leap in operating speed and advanced features, with GDDR7 targeting speeds of 36,000 MT/s and utilizing more advanced signaling methods.

US Institutes GAA-FET Technology EDA Software Ban on China, Stalling sub-3nm Nodes

The US Government has instituted a ban on supply of GAA-FET EDA software to China (the Chinese government and companies in China). Humans can no longer design every single circuit on chips with tens of billions of transistors, and so EDA (electronics design automation) software is used to micromanage design based broadly on what chip architects want. Synopsys, Cadence, and Siemens are major EDA software suppliers. Intel is rumored to use an in-house EDA software that it doesn't sell, although this could change with the company roping in third-party foundries, such as TSMC, for cutting-edge logic chips (which will need the software to make sense of Intel's designs).

GAA or "gates-all-around" technology is vital to building transistors in the 3 nm and 2 nm silicon fabrication nodes. Samsung is already using GAA for its 3 nm node, while TSMC intends to use it with its 2N (2 nm) node. Intel is expected to use it with its Intel 20A (20 angstrom, or 2 nanometers) node. Both Intel and TSMC will debut nodes powered by GAAFETs for mass-production in 2024. The US Government has already banned the sales of EUV lithography machines to China, as well as machines fabricating 3D NAND flash chips with greater than 128 layers or 14 nm. In the past, technology embargoes have totally stopped China from copying or reverse-engineering western tech, or luring Taiwanese engineers armed with industry secrets away on the promise of wealth and a comfortable life in the Mainland.

DDR5 Arrives at 4800 MT/s Speeds, First SoCs this Year

Cadence, a fabless semiconductor company focusing on the development of IP solutions and IC design and verification tools, today posted an update regarding their development efforts for the 5th generation of DDR memory which is giving us some insights into the development of a new standard. The new DDR5 standard is supposed to bring better speeds and lower voltages while being more power-efficient. In the Cadence's blog called Breakfast Bytes, one of Cadence's memory experts talked about developments of the new standards and how they are developing the IP for the upcoming SoC solutions. Even though JEDEC, a company developing memory standards, hasn't officially published DDR5 standard specifications, Cadence is working closely with them to ensure that they stay on track and be the first on the market to deliver IP for the new standard.

Marc Greenberg, a Cadence expert for memory solutions was sharing his thoughts in the blog about the DDR5 and how it is progressing. Firstly, he notes that DDR5 is going to feature 4800 MT/s speeds at first. The initial speeds will improve throughout the 12 months when the data transfer rate will increase in the same fashion we have seen with previous generation DDR standards. Mr. Greenberg also shared that the goals of DDR5 are to have larger memory dies while managing latency challenges, same speed DRAM core as DDR4 with a higher speed I/O. He also noted that the goal of the new standard is not the bandwidth, but rather capacity - there should be 24Gb of memory per die initially, while later it should go up to 32Gb. That will allow for 256 GB DIMMs, where each byte can be accessed under 100 ns, making for a very responsive system. Mr. Greenberg also added that this is the year of DDR5, as Cadence is receiving a lot of orders for their 7 nm IP which should go in production systems this year.

Cadence, Micron Update on DDR5: Still On Track, 1.36x Performance Increase Over DDR4 at Same Data Rate

DDR5 will be the next step in DDR5 memory tech, again bringing increased transfer speeds over the previous JEDEC (the standards body responsible for the DDR specifications) specification. The new memory technology will also bring the customary reductions in operating voltage - the new version will push the 64-bit link down to 1.1V and burst lengths to 16 bits from 1.2V and 8 bits. In addition, DDR5 lets voltage regulators ride on the memory card rather than the motherboard. CPU vendors are also expected to expand the number of DDR channels on their processors from 12 to 16, which could drive main memory sizes to 128 GB from 64 GB today.

DDR5 is being developed with particular attention to the professional environment, where ever-increasingly gargantuan amounts of addressable memory are required. One of the guiding principles over DDR5's development is a density increase (to allow 16 Gbit chips) that would allow for larger volumes of memory (and thus data processing) in the environments that need that. Reduced power consumption also plays a role here, but all of this will have a cost: latency. For end-users, though, this increased latency will be offset by the usual suspects (DDR memory companies such as Crucial, Corsair, just to name some started with the letter C) in tighter timings and increased operating frequencies. JEDEC's specification for DDR5 is set at 4800 MT/s, but it's expected the memory tech will scale to 6400 MT/s, and you know overclocking and performance-focused companies will walk all over the standard.

Cadence and Micron Demo DDR5-4400 Memory Module

Cadence and Micron have joined forces to build the world's first working DDR5-4400 memory module. Cadence provided their DDR5 memory controller and PHY for the prototype while Micron produced the 8 Gb chips, which were manufactured under TSMC's 7 nm process. They were able to achieve 4400 megatransfers per second, which is roughly 37.5% faster than the fastest DDR4 memory that is currently on the market. Nevertheless, Marc Greenberg from Cadence emphasized that DDR5 aims to provide increased capacity solutions, more than actual performance.

The DDR5 standard should facilitate the production of 16 Gb dies and make vertical stacking easier. Restricted by laws of physics, dies eventually get slower as they increased in size. Once you start putting 16Gb die in 1X memory technology, the distances between them starts to get longer. As a result, core timing parameters become worse. Cadence's prototype had a CAS latency of 42 (No, not a typo). Although, the test module does run at 1.1 volts, which makes it quite impressive when compared to DDR4.

Cadence and Intel Collaborate to Enable a 14 nm Tri-gate Design Platform

Cadence Design Systems, Inc., a leader in global electronic design automation, and Intel Corporation, a world leader in computing innovation, today announced that the companies are collaborating to support Intel's 14 nm Tri-Gate process technology to enable customers of Intel Custom Foundry.
