The new MacBook Pros based on the M1 Pro and M1 Max SoCs proved to be very productive in a number of tasks. But mining is definitely not one of them.
There is already a video on the web with a test of a new laptop based on the M1 Pro, and the result cannot be called even just modest. The PC demonstrates a performance of 5 MH / s, which is very, very small. For example, the budget GeForce GTX 1650 reaches about 12 MH / s.
True, the power consumption of a laptop during mining is limited to only 17 W, but this still does not offset the very low performance. Of course, the payback depends on the rate of the cryptocurrency at a particular point in time, but at the moment the MacBook Pro will pay off for about 17 years.
A MacBook Pro based on the M1 Max with a top-end GPU will clearly perform better, but such a laptop is also more expensive. And even with a doubling of productivity, this is still very, very small.
This is the world’s lightest 16-inch laptop. It is equipped with an OLED screen and weighs only 1.1 kg
Acer has launched the world’s lightest 16-inch laptop. Acer Swift Edge was shown a couple of months ago, but now it has become known that the novelty has appeared on sale at a price of $ 1,500.
Acer Swift Edge really impresses with its weight. With a 16-inch screen, the laptop weighs only 1.1 kg! This is not much even for 13-inch models, let alone 16-inch models.
To achieve such a mass, Acer came out, including through the use of an aluminum-magnesium alloy and not the largest battery. It here has a capacity of 54 Wh, which is quite small for a 16-inch model. But this supposedly should be enough for 10 hours of work, according to Acer itself.
But low weight is not all that a laptop can please. First, it also has a 4K UHD OLED screen. Secondly, the Ryzen 6000U processors serve as the heart, which are not only very productive, but also offer very powerful iGPUs.
From the rest, you can note RAM up to 32 GB, SSD up to 1 TB, a pair of USB-C 3.2 Gen2 ports with support for DisplayPort and USB Power Delivery, HDMI 2.1, two USB 3.2 connectors, Wi-Fi 6E and Bluetooth 5.2.
For those same $ 1,500, a far from the most basic version with a Ryzen 7 6800U, 16 GB of RAM and a 1 TB SSD is already available. That is, modifications with the Ryzen 5 6600U will be even cheaper, but there are no prices yet.
Linux has become dangerous – one of the cores of the system can physically disable the laptop display, although not on all models
The Linux kernel 6.0 was recently released and version 6.1 is scheduled to be released soon. However, many users have not switched to it yet. And, as it turned out, one of the old kernels has a problem that affects the video subsystem. It can physically damage the display. This concerns the Linux kernel 5.19.12, but in version 5.19.13 the problem was solved.
The failure only affected laptops with Intel processors that were running a distribution based on the Linux 5.19.12 kernel. The problem seemed to be related to the Intel graphics driver, which caused the display to flash rapidly in white. One of the engineers who is involved in the development of the core of the system explained that it was an incorrect delay in powering up the LCD panel. Because of this, the display could fail, because it is simply not designed to work in this mode for a long time.
It is noted that the problem manifested itself on laptops, where the screens were directly connected to the integrated video core. It was also relevant for models with Nvidia Optimus and some models with Radeon graphics (if available).
It is noted that laptops with AMD processors, conventional and hybrid, are not affected by this problem. Also, the developers advised not to install the “problem” update for those who have not had time to update.
And earlier it became known about a new problem with Windows 11 22H2.
World’s first laptop with RISC-V processor goes on sale It costs $1,500
The ROMA laptop, the world’s first portable computer based on the RISC-V processor, which was introduced last summer, appeared on Alibaba’s Chinese site. This model is priced at $1499.
At the moment, the manufacturer plans to ship about 100 units by the end of the year, and up to 1,000 more in the first quarter of 2023. At the same time, to purchase, you need to contact the supplier directly, clarify the price and specifications before placing an order.
The laptop itself is the result of a partnership between China’s DeepComputing and Xcalibyte. It is built on the Alibaba T-Head TH1520 processor with four 64-bit Xuantie C910 cores, which operate at a frequency of 2.5 GHz. It also has a neural processor with a performance of up to 4 TOPS and an Imagination graphics chip.
The laptop is equipped with a 14.1-inch screen with a resolution of 1920 x 1080 pixels, 16 GB of RAM and 256 GB of permanent memory. Other features include a backlit keyboard, SD card reader, HDMI, USB-C, USB-A and Ethernet ports, Wi-Fi 5 and Bluetooth adapters, and a 1080p webcam.
For now, such a system will be of interest only to enthusiasts and developers, but this is the first mass alternative to x86 and Arm processors that has appeared on the market.
