Linux 4.20 Release – Main Changes, Arm and MIPS Architectures

After Greg K-H handling Linux 4.19 release, Linus Torvalds is back at the helm, and released Linux 4.20 just before Christmas: Let’s face it, last week wasn’t quite as quiet as I would have hoped for, but there really doesn’t seem to be any point to delay 4.20 because everybody is already taking a break. And it’s not like there are any known issues, it’s just that the shortlog below is a bit longer than I would have wished for. Nothing screams “oh, that’s scary”, though. And as part of the “everybody is already taking a break”, I can happily report that I already have quite a few early pull requests in my inbox. I encouraged people to get it over and done with, so that people can just relax over the year-end holidays. In fact, I probably won’t start pulling for a couple of days, but otherwise let’s just […]

Banana Pi to Launch a 24-Core Arm Server

SinoVoIP has been offering Banana Pi single board computers for several years. Their boards are generally based on Arm processors, offered at a relatively decent price, although not as quite as good value as FriendlyELEC and Orange Pi ones. The company is also known for providing subpar documentation and firmware images, but a fairly active community still formed around their boards 🙂 The company has now demonstrated something a little different with a 24-core Arm server that should eventually be sold as a Banana Pi server board or actual server, as the full details are yet to be known. We did not get a glimpse at the actual hardware, but the blurry photo above gives some clues. We have 24-core Arm Cortex A53 processor with 32GB RAM (29.4GB seen by the OS) running Ubuntu 18.04.1 LTS with MATE desktop. There aren’t that many 24-core Arm Cortex A53 processors, so unless […]

Arm Cortex-A65AE Targets Safety-Critical Automotive, Aviation, and Industrial Automation Applications

Arm introduced their first “Automotive Enhanced” processor with Cortex-A76AE last September. The processor targets autonomous driving applications, and comes with extra safety features such Dual Core Lock-Step (DCLS) running the same code on two different cores to continuously check the execution result is the same on both. The company has now unveiled a second AE core with Cortex-A65AE, which Arm claims is the first multithreaded Automotive Enhanced Cortex-A CPU technology to deliver the highest safety levels with Dual Core Lock-Step (DCLS). Arm Cortex-A65AE specifications: Architecture – Armv8-A (Harvard) Extensions – Armv8.1, Armv8.2, Cryptography, RAS, and Armv8.3 (LDAPR instructions only) ISA support – A64 Microarchitecture Out-of-order Pipeline Superscalar NEON/Floating Point Unit Optional Cryptography Unit Max number of CPUs in cluster – Eight Physical Addressing (PA) – 44-bit Dual Core Lock-Step Memory system and external interfaces L1 I-Cache / D-Cache – 16KB to 64KB L2 Cache – 64KB to 256KB L3 Cache […]

Qualcomm Snapdragon 8cx 7nm Processor is Designed for Always-Connected PCs

The first day of Qualcomm Tech Summit focused on 5G technology, the second day revealed details about Snapdragon 855 mobile processor, and the third and last day was about Snapdragon 8cx Compute Platform, a 7nm processor specifically designed for always-on always-connected PCs that performs as well as some 15W processor(s) from Intel, but at much lower power consumption. Snapdragon 8cx specifications: CPU – 8x Qualcomm Kryo 495 64-bit cores (dual cluster) with a total of 10MB cache; 7nm Process Technology Visual Subsystem – Qualcomm Adreno 680 GPU with DX12 support, 128-bit memory interface Memory – LPDDR4x, 8 Channels Storage – NVME SSD, UFS3.0 Qualcomm Artificial Intelligence Engine Qualcomm Hexagon 685 DSP Qualcomm All-Ways Aware technology AI features 4th Generation Qualcomm AI Engine Enhanced voice assistant experiences for Alexa and Cortana with Qualcomm Aqstic technology Display Maximum On-Device Display Support: 4K Dual 4K external displays support Audio Qualcomm Aqstic audio technology […]

Amazon EC2 A1 Arm Instances Deliver up to 45% Cost Savings over x86 Instances

Just a couple of days ago, Amazon introduced EC2 A1 Arm instances based on custom-designed AWS Graviton processors featuring up to 32 Arm Neoverse cores. Commenters started a discussion about price and the real usefulness of Arm cores compared to x86 cores since the latter are likely to be better optimized, and Amazon Web Services (AWS) pricing for EC2 A1 instances did not seem that attractive to some. The question whether it makes sense will obviously depend on the workload, and metrics like performance per dollar, and performance per watt. AWS re:Invent 2018 is taking place now, and we are starting to get some answers with Amazon claiming up to 45% reduction in costs. It sounds good, except there’s not much information about the type of workload here. So it would be good if there was an example of company leveraging this type of savings with their actual products or […]

Amazon Launches 64-bit Arm Server “A1” Instances

Amazon has developed AWS Graviton processors optimized for cloud applications and delivering power, performance, and cost optimizations over their Intel counterpart. The processors feature 64-bit Arm Neoverse cores and custom silicon designed by AWS themselves, and can be found today in Amazon EC2 A1 instances. The screenshot above shows Amazon Linux 2, Red Hat Enterprise Linux 7.6, Ubuntu 18.04 Server, and Ubuntu 16.04 Server machine images having options for either 64-bit x86 or 64-bit Arm servers. Amazon Arm server instance are particularly suitable for applications such as web servers, containerized microservices, caching fleets, distributed data stores, as well as development environments. Amazon further explains: A1 instances are built on the AWS Nitro System, a combination of dedicated hardware and lightweight hypervisor, which maximizes resource efficiency for customers while still supporting familiar AWS and Amazon EC2 instance capabilities such as EBS, Networking, and AMIs. Amazon Linux 2, Red Hat Enterpise Linux […]

An Attempt to Benchmark Entry-level x86 Boards against RK3399 & Exynos Arm Boards

Some Arm boards have become quite powerful, while hardware based on low power Intel processor has generally become cheaper with both architectures somewhat converging in terms of performance and price. Piotr Maliński got interested and purchased some low cost (<$150) Intel hardware to compare to mid-range Arm boards, throwing a Raspberry Pi 3 B+ into the mix as well for comparison. Those are the Intel test boards / computers: Qotom motherboard with Intel Atom Z3735F Bay Trail processor, 2GB RAM, 32GB flash – $74 + shipping on Aliexpress Piesia nano ITX board with Intel Celeron N2806 Bay Trail processor, DDR3 SO-DIMM socket, SATA / mSATA interfaces – Piotr found it for around $85 on Aliexpress, but the price now jumped to over $150 plus shipping, which does not make it very attractive Generic thin mini ITX motherboard based on Celeron N3160 “Braswell” processor, DDR3 SO-DIMM socket, SATA / mSATA interfaces. $62.68 […]

HiSilicon Kirin 980 Benchmarks Show Cortex A76’s Impressive Performance & Efficiency Improvements

HiSilicon Kirin 980 was the first processor announced with Cortex A76 cores, which were said to deliver laptop-class performance, with 35% performance improvement over Cortex A75, and around twice the performance of Cortex A73 cores thanks to improvements, and a higher CPU frequency up to 3.0 GHz. But now that Huawei Mate 20 / Mate 20 Pro smartphones are out, various reviews have been published, and Anandtech was mostly able to confirm the claims. In most case, actual results were inline with expectation despite Kirin 980 clock speed being “limited” to 2.6 GHz. Looking at GeekBench 4 single-thread integer and floating-point scores, the Cortex A76 core based Kirin 980 is significantly faster than Cortex A73 powered Snapdragon 835 clocked @ 2.45 GHz. Precisely: 1.77x faster in the integer score,and 2.21x faster in the floating point score. SPECS2006 confirmed the good performance with 1.89x higher integer score, and 2.04x faster for […]
