The Rise of AMD's Zen Architecture

Over the past few years, AMD has made significant strides in the world of processors with its Zen architecture. The launch of the Ryzen 2000 series processors powered by the Zen 2 architecture was just the beginning. With an aggressive roadmap for the future, AMD is already in development for Zen 3 and Zen 4. However, what caught everyone's attention was the confirmation of the existence of Zen 5 in a video released by AMD during the Ryzen processors launch. In this article, we will delve deeper into the details of Zen 5 and what it means for the future of AMD processors.

Zen 5: The Future of AMD Processors

Zen 5 is the internal code name for a future generation of the Zen architecture. While the details of Zen 5 are subject to change, the confirmation of its development by AMD indicates the company's commitment to pushing the boundaries of processor technology. Although Zen 4 is also in development and expected to launch in 2021, Zen 5 is projected to hit the market around 2022. The transition from 7nm+ in Zen 3 to 5nm in Zen 4 is expected, signifying AMD's dedication to advancements in transistor technology.

Zen 5 vs. Zen 4: What's the Difference?

It is important to note that Zen 5 and Zen 4 are two distinct architectures in AMD's roadmap. Despite the confusion surrounding the similar numbering, Zen 4 is indeed in development alongside Zen 5. While Zen 4 is expected to utilize the 5nm process, Zen 3 will make use of the 7nm+ node. The details of the differences between Zen 5 and Zen 4 are still unknown, but one can anticipate a significant leap in performance and efficiency with each iteration.

TSMC's 5nm Technology and its Impact on Zen 5

TSMC's 5nm technology plays a crucial role in the development of Zen 5 processors. According to documentation provided by TSMC, their 5nm node offers a 1.8 times increase in logic density and a 15% speed gain compared to the 7nm process. The transition to 5nm allows for better performance, improved power efficiency, and an overall competitive edge in the industry. AMD believes that most customers using the 7nm process will adopt 5nm technology, resulting in an increased product portfolio and a larger addressable market.

AMD's Aggressive Roadmap and the Competition with Intel

AMD's roadmap showcases their aggressive plans for future processor releases. With Zen 5 in development, in addition to Zen 3 and Zen 4, AMD aims to dominate the market across various industries. This puts Intel in a challenging position, as they will face tough competition from AMD's advancements in core counts, IPC gains, and higher frequencies. Over the next few years, we can expect Intel to face increased competition from AMD, giving consumers more choices and driving innovation in the processor market.

PCIe 4.0 and Older Boards: A Confusing Situation

The introduction of PCIe 4.0 has caused some confusion, particularly in relation to older boards such as the X470. While certain motherboard manufacturers, like Asus, provided BIOS updates to enable PCIe 4.0 support on some motherboards, AMD has stated that they do not officially support PCIe 4.0 on older boards. This has led to a dilemma for users - whether to utilize a beta BIOS to gain PCIe 4.0 support or stick with the older BIOS for stability. The compatibility of PCIe 4.0 with older boards remains an ongoing discussion, with potential performance improvements for high-performance SSDs.

Intel's Next Generation Atom Processors and the Introduction of Level 3 Cache

Intel is also making advancements in processor technology with its next generation Atom processors. The upcoming Tremont architecture is set to feature level 3 cache, which enhances performance by providing faster memory access. While level 3 cache offers performance benefits, it also increases power consumption. Despite this trade-off, Intel believes the performance improvements justify the presence of level 3 cache. The cache layout and other details are yet to be revealed, but this development will undoubtedly impact the performance of Atom processors.

Intel's Neuromorphic Loihi Chip: A Revolution in Computing

In addition to their processor developments, Intel is also working on the Neuromorphic Loihi chip. This unique chip, which does not rely on a global clock signal, can contain up to 128 cores and is based on the 14nm process. The Loihi chip has been praised for its lower power consumption compared to GPUs and specialized IoT inference hardware. Benchmark results have shown a significant improvement in power efficiency while maintaining real-world performance. The research team is currently exploring various applications for neuromorphic computing and its potential in commercial environments.

Conclusion

The future of AMD processors looks promising with the confirmation of Zen 5 and the company's aggressive roadmap. As AMD continues to push the boundaries of processor technology, they pose a significant challenge to Intel's dominance. With TSMC's 5nm technology and advancements in transistor technology, AMD aims to deliver higher performance and efficiency with each architecture. The compatibility of PCIe 4.0 with older boards remains a topic of discussion, while Intel's introduction of level 3 cache in their next generation Atom processors shows their commitment to innovation. Additionally, Intel's Neuromorphic Loihi chip offers a glimpse into the future of computing. Exciting times lie ahead for both AMD and Intel as they race towards the next era of processor technology.
