IBM unveiled the Power10 processor: 7nm EUV energy efficiency increased by 3 times

IBM's Power series is one of the few processors that are more powerful than x86. IBM announced the latest generation of Power10 series processors on August 17, designed to meet the needs of enterprise-level hybrid cloud computing. IBM stated that it started designing the Power10 processor five years ago, incorporating hundreds of new patented technologies, claiming to be three times more energy-efficient than Shang Power9, bringing support including PCIe5.0, DDR5, and providing a single chip with 15 cores and 120 threads, With the new MemoryInception technology, it can support PB-level memory.


IBM only announced the Power10 product for the first time, and its specific specifications have not been announced. IBM mentioned performance comparison in the remarks. From a two-way system composed of two 30-core Power10, the new generation of Power10 series processors will have up to 30 cores. Power10 embedded matrix math accelerator (MatrixMathAccelerator), FP32, BFloat16, INT8 data format AI reasoning performance is 10 times, 15 times, 20 times that of Power9. In terms of security, it supports new hardware-based technologies, including transparent memory encryption for end-to-end security. The number of each core AES encryption engine is four times that of the previous generation Power9. It strengthens container security and provides future-oriented quantum encryption and homomorphic encryption. be prepared.
Manufacturing process, IBM upgraded from Power9’s GlobalFoundries 14nmSOI process to Samsung’s 7nmEUV process, integrating 18 billion transistors and a core area of 602mm2. Although Samsung announced mass production of the 7nmEUV process in 2018, the maturity and yield of the technology have not been well resolved. This time IBM is pushing to announce the Power10 processor. Does it mean that Samsung has completely solved the related problems In addition, Samsung 7nmEUV can be used to manufacture large-size 600mm2 chips. Can it take away some of the orders from TSMC
The Ampere GA100GPU manufactured by TSMC for NVIDIA also uses the 7nmEUV process, integrating 54 billion transistors in a core area of 826mm2, and the transistor density is much higher than that of IBM's Power series processors. But considering that the complexity of CPU transistors is much higher than that of GPUs, such a density of transistors is also explained.
The IBM server system based on the Power10 platform will be available in the second half of 2021.

AMD's GPU technology enters the mobile phone chip market for the first time

In addition to the release of the Exynos2100 processor, Samsung also confirmed a major event at this Exynos event, that is, the custom GPU that they have worked with AMD for many years will soon appear and will be used on the next flagship machine. The current Exynos2100 processor uses ARM’s Mali-G78GPU core with a total of 14 cores, so the GPU architecture developed by Samsung will be the next Exynos processor, and the GPU will be the focus. This is probably the meaning of Exynos2100’s GPU stacking. The key reason. Dr. InyupKang, president of Samsung’s LSI business, confirmed that the next-generation mobile GPU in cooperation with AMD will be used in the next flagship product, but he did not specify which product. Samsung is not talking about the next-generation flagship but the next one, so it is very likely that a new Exynos processor will be available this year, either for the GalaxyNote21 series or the new generation of folding screen GalaxyZFold3. In 2019, AMD and Samsung reached

Apple and Intel want to join the game, what happened to the GPU market?

Intel recently announced that it will launch Xe-LP GPU at the end of this year, officially entering the independent GPU market, and will hand over to TSMC for foundry. At the 2020 WWDC held not long ago, Apple also revealed that it is possible to abandon AMD's GPU and use a self-developed solution based on the ARM architecture. It will launch a self-developed GPU next year. What happened to the GPU market? Why are the giants entering the game? 　　 Massive data calls for high-performance GPU 　　 Why has the demand for GPUs increased so rapidly in recent years? Because we are entering an era where everything needs to be visualized. Dai Shuyu, a partner of Aiwa (Beijing) Technology Co., Ltd., told a reporter from China Electronics News that visualization requires a large amount of graphics and image computing capabilities, and a large amount of high-performance image processing capabilities are required for both the cloud and the edge. 　　 Aiwa (Beijing) Technology Co., Ltd. is an enterp

SSD vs. HDD: that is nice for You?

Deciding on the proper garage isn’t just about comparing ability and value. The type of garage your pc uses topics for overall performance, inclusive of electricity utilization and reliability. Stable country drives (SSDs) and difficult disk drives (HDDs) are the 2 major storage options to consider and it’s critical to realize the satisfactory use for each and how they compare facet by using aspect. What is an HDD? An HDD is a statistics garage tool that lives within the pc. It has spinning disks inside where statistics is saved magnetically. The HDD has an arm with several "heads" (transducers) that study and write statistics at the disk. It is much like how a turntable file participant works, with an LP record (tough disk) and a needle on an arm (transducers). The arm moves the heads throughout the surface of the disk to get admission to distinct information. HDDs are considered a legacy generation, that means they’ve been round longer than SSDs. In popular, they may be dec
