User exposes Samsung Space Zoom technology: shooting the moon with it has little to do with real photography
A user of the American Reddit forum with the nickname ibreakphotos conducted an investigation that draws on a sensation. He showed by illustrative example that the Space Zoom technology implemented in Samsung flagships and used, among other things, for shooting the Moon (and what kind of flagship is it that cannot photograph the Moon normally?), It relies not so much on the capabilities of the optical system and smartphone sensors, how much for artificial intelligence algorithms.
The experiment itself is quite simple. The user downloaded a high-quality image of the moon from the Internet, then reduced it to a size of 170 x 170 pixels and blurred it, thereby “killing” all the detail. After that, he enlarged the picture of the image four times, turned off the lights in the room, thereby simulating the night, displayed the picture on his monitor and photographed such an artificial moon – naturally, using the Space Zoom technology. And then … a comparison of two pictures follows: before and after.
It can be seen that the image from the smartphone (on the right) has details that are not and could not be in the original image (left). Where did they come from?
ibreakphotos believes that when shooting the moon, the phone processes the image using artificial intelligence algorithms. Simply put, Samsung has trained a neural network on hundreds (if not thousands) of images of the moon, and now the results of the AI work are added to all photos of the natural satellite. As a result, details appear in the pictures (for example, craters) – which the phone either cannot capture in principle, or cannot capture in good quality.
Naturally, the test results caused a flurry of criticism against Samsung. Perhaps it would have been less if the company had not advertised both Space Zoom and shooting the Moon with it, but this is what was presented as an outstanding feature of the Galaxy S23 camera even in pre-release teasers.

Nvidia says its Grace CPU Superchip is twice as fast as x86-compatible processors for the same power consumption
Nvidia said that its Arm-based Grace CPU Superchip processor in tests with real workloads shows a twofold increase in performance compared to x86-compatible CPUs in the same range of power consumption. With which processors Nvidia compared, it is not specified.
The company says these figures mean data centers can handle twice as much peak traffic for the same power consumption if they switch to Grace. Or they can cut their energy bills by almost half while maintaining productivity.
Nvidia itself says that Grace provides such results thanks to three main factors. Firstly, these are 72 Arm Neoverse V2 cores in one CPU (Grace CPU Superchip, we recall, contains two CPUs on one board), and secondly, in fact, the combination of two such CPUs via the NVLink-C2C interface with a bandwidth of 900 GB / s , third, the use of server-class LPDDR5X memory.

Realme GT Neo5 SE on Snapdragon 7 Plus Gen 2 tested in AnTuTu. The result is like recent flagships
Qualcomm officially unveiled mid-range Snapdragon 7 Plus Gen 2 single-chip system a few days ago, and already one of the first production models based on this SoC – Realme GT Neo5 SE – has been spotted in the AnTuTu benchmark.
The result is impressive. Snapdragon 7 Plus Gen 2 is not a top platform at all, but a phone based on it has broken the mark of 1 million points. Until recently, only flagships were capable of this. For comparison, this is the level of the Dimensity 9000 and Snapdragon 8 Gen 1 platforms.
As for the specifications of the Realme GT Neo5 SE, it has 16 GB of LPDDR5X RAM, 1 TB (!) of UFS 3.1 memory and Android 13 out of the box. This smartphone will go on sale on April 3rd.
Electric Cars
Truck “Ural” tried on a hybrid power plant. The company showed its first such prototype and set its sights on an all-electric version.
The Ural Automobile Plant demonstrated its first prototype of an electric truck equipped with a hybrid power plant.
A car with a 4×2 wheel formula is still called simply “Ural”. It is powered by an LNG engine that is used as a generator to charge a battery, which in turn powers an electric motor. At the moment, it is known that the power reserve is only 100 km, but in this case, we mean the ability of a car to drive such a distance solely due to the battery. Since the car is also equipped with an internal combustion engine, as a result, in general, the power reserve is quite worthy of 500 km.
The company is reportedly planning to develop an all-electric truck and then a hydrogen fuel cell version. But so far we are only talking about prototypes, but there is no data on serial machines with similar power plants.
