The next generation AMD architecture does not use the 5nm manufacturing process

Lisa Su, CEO of AMD, recently announced that the company’s focus In Zen and rDNA the future will be on architecture, not lithography. This statement was made only shortly after the end of the previous financial season of this company; The season with the presence of 7nm AMD products such as Epic series, Ryzen and Radeon , marked the company’s most profitable financial quarter since 2005.

The CEO of the hardware giant said in response to a reporter’s question about the company’s current 7nm series processing technology and architecture:

Let Let me answer this question like this. We have made many choices and lithography and architecture were among these choices. In my opinion, we have made good choices.

We are no longer looking at lithography as the main driver. From our point of view, lithography is very important and progress in it is also considered very important for us; And today we have benefited a lot from 7nm technology. But at the right time and to get the most benefit, we will go to 5 nm technology. We are currently focusing a lot on architecture, and in my opinion, architecture is what can differentiate our products from the competition and push them forward.

AMD plans to improve its architecture based on 7nm lithography before migrating to 5nm lithography

AMD’s Zen and rDNA architecture-based processing cores are the first The chips are made with TSMC’s new 7nm manufacturing process. According to AMD’s CEO, the company plans to focus on the architecture of its processors to get the most performance with the current 7nm technology. This means that 7nm technology will be optimized as much as possible for the next generation Zen family and rDNA, but 5nm technology will not be removed from the company’s roadmap.

AMD will switch to 5nm technology, only at a more appropriate time AMD has confirmed its upcoming processor cores up to 5th Gen and the next-gen rDNA architecture for 2020. During this period, AMD will work on improving the 7nm technology, which is known as +7; Also, due to being ahead of its usual competitor, Intel does not feel the need to use inferior lithography. Intel’s 2019 products are still based on 14nm lithography, and according to predictions, the company’s 2020 products will switch to 10nm technology. Like Zen+, which uses 12nm FinFET technology to significantly improve Ryzen and Rayon products. The next generation Zen 3 and rDNA 2 will also be based on +7nm, which will improve overall performance. Of course, the improvement caused by the architecture will not be as effective as lithography, and AMD cannot maneuver much on the architecture.

AMD has just updated its roadmap showing that Zen 3, the architecture used in Milan processors, will be released in 2020. The 7nm+ based Zen 3 will compete with the 10nm Ice Lake-SP and the 14nm Cooper Lake Xeon++. AMD emphasized that its processors have more performance per watt, and looking at the slide, we can see that even Epic ROM processors are designed to compete with Intel’s Xeon 2020 series. This is something that AMD has been emphasizing since 2018 and since the design of Epic Rome.

AMD Chief Technology Officer, Mark Pipermeister, said that Zen 3 will be based on Zen 2 and only efficiency and performance. Overall, it will improve.

Moore’s law has had a downward trend. Semiconductor nodes have become more expensive and we are not getting the frequency increases that we want. Using 7nm + technology with Extreme Ultraviolet Lithography (EUV) brings us a decent performance boost.

AMD is already incorporating some of the most advanced technologies in the hardware industry with the Zen chiplet design in processors. It has Ryzen and Epic. During a presentation in the UK, AMD announced that we will see major changes in the Milan 2020 processors, such as a cache redesign and having 8 cores inside a CCX.

AMD Zen 3, an improved version of Zen 2

One of the flagship products based on the Zen 3 architecture will be the third generation of Epic server processors known as Milan. This series of processors will be used in the new Pearl Motor supercomputer. Initial technical specifications show that the Milan processors will have 64 cores, 128 processing threads and AVX2 SIMD. There will also be 8-channel DDR RAM support.

In addition to Zen 3, AMD has also confirmed Zen 4 and Zen 5 technologies. The third generation of Epic processors is officially called Genova. The Zen 4 is currently in development and is slated for release in 2021 or 2022. In this architecture, lithography below 7 nm will be used.

rDNA 2 GPU architecture

from processors Let’s move on to GPUs. In addition to Zen 3, AMD also unveiled the RDNA 2 GPU architecture, which is currently being designed and is being prepared for release in 2020. This architecture will likely see many improvements over current 7nm+ GPUs. rDNA 2 GPUs will probably be released in late 2020.

We don’t know much about rDNA 2 other than a few rumors, but AMD has officially talked about Ray Tracing support in its next generation of GPUs. In the next generation of AMD GPUs, we will see this company’s parity with Nvidia’s RTX technology.

AMD also wants to use rDNA 2 in its high-end GPUs. Although the first generation of rDNA graphics processors in the price range of 300 to 500 dollars had excellent performance, in the second generation of this architecture we expect to see the Radeon RX series based on rDNA 2. These processors will directly compete with Nvidia’s RTX 2080 SUPER and RTX 2080 Ti processors. Of course, Nvidia is not a company that will give up the competition easily to its competitor. This company has a plan to release graphics processors based on its 7nm architecture in 2020, which will probably be called Ampere.

It should be noted that the high-end Navi GPU will likely retain the same high-bandwidth memory design as the current flagship. Of course, AMD will probably go for the newer HBM2E VRAM.

HBM2E DRAM uses 8 slots and 16 gigabit memories, which together and by setting the clock speed at 2.3 Gbps will lead to a bandwidth of 410 gigabytes per second individually and 920 gigabytes with two HBM2Es. Which is a stunning figure. According to Samsung, the HBM2E product can provide up to 64 memories and a bandwidth of 1.64 TB per second. Such products will be suitable for use in servers and workstations.
