For many years, AMD has been competing with Intel, the world's largest chip maker. In order to obtain a more favorable market position, AMD is planning to introduce the latest Zen series chips, which may become ten. During the year, the most competitive chip products, AMD's senior research element and Zen chip design engineer Michael Clark revealed some details about Zen at a chip development conference in Cupertino, Calif., Tuesday. If the Zen series was successfully released, Intel’s billions of chip business will be hit by AMD, and Patrick Moorhead, chief analyst of Moor Insights & Strategy., said: “This is a very good thing. Although it will take a little time for the official launch, I believe that AMD currently has the best opportunity in history. It can be said that this is the biggest thing for AMD in the past decade."
AMD President Lisa Su and Mark Papermaster stated that the Zen chip is a breakthrough research achievement of AMD. In the benchmark test provided by AMD, its performance surpassed that of Intel’s fastest 10-core Broadwell-E chip. As time goes by, this chip can also be loaded into thin notebooks, high-end game books and data center servers. It is the work of hundreds of AMD engineers, and AMD also simplified a series of work to focus on the development of this chip. .
AMD's first two 8-core and 16-thread based on the Zen core is the Summit Ridge desktop chip and the 32-core, 64-threaded Naples chip. The Summit Ridge chip will be released in the fourth quarter of this year, while the Naples will be released in the second quarter of next year. Gartner analysis Martin Reynolds said: "This gives Intel enough time to catch up, but we still need to wait for AMD's final product to be announced before deciding whether or not Intel will be defeated. It is still uncertain."
So far, Intel has released 7 generations of core processors, but they are also preparing for the launch of next year's new Xeon Phi series chips. Historically, Intel chips have been faster than AMD's at the same time. It is more advantageous, but this time AMD is positive. As Clark said: "We are ready to compete with Intel."
AMD used a 14-nm fin field-effect transistor (FinFET) from contract chip manufacturer GlobalFoundries. Through this technology, the chip's processing efficiency and performance can be greatly improved, which provides AMD competition with Intel's advantages. , 3GHZ Zen chip processor's previous Excavator processor 1.4 times faster, Papermaster said the most significant improvement lies in the redesign of the cache, to improve branch prediction while achieving multi-threading, the new design can also be more effective control The power consumption of the chip, these changes all make the chip can catch data faster, predict the data that needs to use, handle many tasks at the same time, AMD adopts the new technology that never had before.
Clark said: "In the design process, we use the tracking tool to simulate power consumption and weigh the ratio between processing efficiency and power consumption. You can clearly see where a wrong decision has been made and where the infrastructure is out of balance. The power consumption problem of Intel's X86 architecture is most obvious. Due to the variable-length instructions, it is difficult for the X86 architecture to handle multiple tasks at the same time. As a result, power consumption is wasted on a single narrow-channel path, and AMD will first pass branch prediction. To judge where data and instructions are about to appear, although there are many processors that use this method, AMD is more efficient. We use micro-ops to memorize previously executed instructions so that we can perform the next processing based on memory. The speed can be much faster. A better caching system also means that there will be no problem with some processing units being idle during processing. All processing units will prepare for the next data acquisition, compared to the previous four. AMD's Zen processor upgrades to 6 micro-ops per revolution, improving processing speed while keeping the design structure simple . "
Clark also said: "This is only AMD's first Zen series chip, follow-up there will be many upgrades and develop more high-performance Zen products. In short, the powerful AMD has come back!"
