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.
Huawei introduced an extraordinary laptop Qingyun L420 – with a 2K screen, Arm platform and Linux OS
According to the source, Huawei has a new laptop Qingyun L420, and this is the successor to the previously released Qingyun L410. The peculiarity of the novelty is that it is built on the Arm platform, therefore, to some extent, such a device can be considered a competitor to MacBook laptops on Apple’s own platforms. At least the concept is the same: using the Arm platform and Linux OS.
The Qingyun L420 is built on a 5nm Kirin 9006C SoC with eight cores up to 3.13GHz. The amount of RAM – 8 GB, flash memory – 256 or 512 GB. The screen is characterized by a diagonal of 14 inches and a resolution of 2160 x 1440 pixels. The peculiarity of the model on the Arm platform is that it is lightweight, practically not subject to heat and lasts for a long time. Thus, the device weighs 1.45 kg, and the battery capacity is 56 Wh.
Qingyun L420 is equipped with a Wi-Fi 6 wireless adapter, a set of interface connectors are represented by mini-RJ45 ports, two USB-A, one USB-C, and a standard headphone jack. Pricing is not disclosed, but the current Qingyun L410 model with Linux pre-installed costs about $ 1,400. And the novelty will either cost the same or be more expensive.
Shipments of desktops, laptops, tablets and workstations in the United States fell 16%
Experts of the analytical company Canalys have summed up the results of the third quarter of 2021 in one of the most important world markets for ready-made PCs – the American one. This market situation reflects the overall picture of the global PC market, which Canalys includes desktops, laptops, tablets and workstations.
In the third quarter of 2021, 30.3 million systems of these categories were sold in the United States, which is 16% less than in the third quarter of 2020.
Notebook shipments totaled 17.1 million units, down 15% year on year. This is due to the sharp drop in Chromebook sales as the education market has reached saturation. Tablet shipments fell 24% to 10.0 million units. Analysts attribute this to a decline in consumer demand. Desktop computers stand out against this background – their shipments grew by 6% and reached 3.2 million units. According to experts, this is due to the return of workers to offices and an increase in purchases in the corporate segment.
Dell was # 1 in the US PC market in the third quarter. It increased sales by 10.4%, which led to an increase in Dell’s share from 22.3% to 27.6%. At the same time, HP, ranked second, reduced sales by 30.7%, which resulted in a decrease in its share from 33.4% to 26.0%. Ranked third, Lenovo increased sales by 2.9%. Its share increased from 15.0% to 17.4%. This is followed by Apple, which reduced sales by 13.7%. Apple’s share fell from 11.9% to 11.6%. Acer closes the top five. It reduced sales by 31.1%, which led to a decrease in its share from 5.6% to 4.4%.
Some newer MacBook Pro 16s have MagSafe issues. Laptops simply won’t charge when turned off
Some new MacBook Pro 16 owners have encountered issues with MagSafe magnetic charging.
The problem is as simple as possible: laptops do not charge when the charger is connected via MagSafe. In this case, the indicator instead of green blinks yellow. The important thing is that the problem only occurs when the laptop is turned off (closed). When the mobile PC is active, charging takes place normally.
It’s unclear how common the problem is, but at least one user has already talked to Apple’s service center, and the company eventually decided to replace the laptop. Unfortunately, so far there are no other solutions to the problem.
