With different processors The Soonnooz company presented a very unusual-looking mini-PC Soon Mini, which also has an original design.  [caption id="attachment_85427" align="aligncenter" width="780"] Soonnooz Mini PC[/caption] As you can see, the design of the device is clearly inspired by technology from the middle of the last century. If you don’t know, you can hardly guess that it is a computer.  [caption id="attachment_85428" align="aligncenter" width="711"] Soonnooz Mini PC[/caption] Soonnooz Mini PC introduced But design is not everything. If you look closely, you can see that the body seems to consist of two parts: the main and the front. And this is true, because the front part is detached from the main one. For a regular PC, this wouldn't make sense, but the point is that this very detachable part is a portable speaker. A special stand has even been created for it. All this feature is perfectly demonstrated in the official video.  https://youtu.be/MJKNuVGSf9w As for the PC itself, the new product could be based on the Ryzen 7 7735HS, Ryzen 7 7840HS or Intel N100. But it seems there are older versions of the same mini PC with older processors.   Also worth noting are the dimensions 250 x 250 x 68 mm, Bluetooth 5.3, up to 32 GB of RAM, 512 GB SSD, Wi-Fi 6E, a good set of ports (a pair of USB-C 3.1, a pair of USB 3.0, HDMI, RJ45). Separately, it is worth mentioning the battery: the mini-PC is equipped with a battery with a capacity of 6000 mAh, which can be enough for several hours of operation, although this, of course, will greatly depend on the operating mode and the CPU used. 

And eight small ones While Intel Meteor Lake processors have not yet entered the market, the Arrow Lake CPU line, which is expected next year, has appeared on the Internet. [caption id="attachment_84812" align="aligncenter" width="780"] CPU Arrow Lake-H[/caption] CPU Arrow Lake-H with six large cores appeared on the Internet We are talking about the Arrow Lake-H mobile processor. It has six large and eight small cores. We don't yet know all the details about the Arrow Lake configuration, but such CPUs will have a maximum of eight large and 32 small cores. It is expected that the Arrow Lake-H line will offer up to 6 + 8 configurations, like the specified model, and Arrow Lake-HX processors will have 8 + 16 or 8 + 24 cores. [caption id="attachment_84813" align="aligncenter" width="534"] CPU Arrow Lake-H[/caption] Arrow Lake processors are expected in the second half of next year. Unlike Meteor Lake, which is focused primarily on energy efficiency, Arrow Lake will be more versatile and represented in more segments, including the most senior one.

There are still a few years left before such a memory is released. HBM4 memory will appear on the market only in a few years, but it has already become known that its appearance may be associated with a small revolution in the field of semiconductor production. Hynix is ​​reportedly working with Nvidia and other manufacturers on technology that will allow HBM4 memory chips to be placed directly on the computing chip. [caption id="attachment_83411" align="aligncenter" width="600"] CPUs and GPUs[/caption] Now HBM memory is placed on the same substrate as the CPU or GPU, but next to it. Placing memory on the CPU/GPU will not only change the way logic and memory devices are typically connected, it will also change the way they are manufactured. This will change the way CPUs and GPUs are made. In fact, this is approximately the same as AMD's 3D V-Cache, only with a different type of memory. SK Hynix has now begun recruiting specialists to design logic semiconductors such as CPUs and GPUs and is discussing its HBM4 integration design method with several companies without its own manufacturing capabilities, including Nvidia. It is likely that Hynix and Nvidia will initially jointly develop a specific GPU, and then TSMC will produce this chip and immediately place HBM4 memory on top. Considering the type of memory, we are clearly talking about specialized accelerators for AI or data centers. [caption id="attachment_83412" align="aligncenter" width="385"] CPUs and GPUs[/caption] Hynix took on this idea for a reason. The thing is that HBM4 memory will use a 2048-bit interface to connect to host processors, so the latter will be extremely complex and expensive. A direct connection between memory and CPU/GPU will simply be cheaper. However, it is too early to draw any conclusions, since on the way to such implementation there is a very banal problem - heating. The consumption of the Nvidia H100 accelerator is very high, and in a few years such solutions can consume much more. Memory also consumes a lot, and when all this is placed next to each other, there are no problems with cooling. And when a “sandwich” is created, the heating increases significantly with a smaller area of ​​the final crystal. Perhaps Nvidia accelerators in a few years will initially be designed exclusively for liquid cooling.

For free Bitsum has released the CoreDirector application, which allows you to optimize the performance of Intel processors with small cores.  [caption id="attachment_83317" align="aligncenter" width="780"] Intel processors[/caption] To make small cores of Intel processors work normally. It is essentially a thread scheduler that allows the user to configure the CPU to force small CPU cores to be used or not used in the selected application. Of course, we are talking about 12th generation Core processors and newer, which generally have these small cores.  The software is very simple. In fact, it has only three operating modes: small cores are forcibly disabled, forcibly enabled, or their control is given to the OS to a greater extent - this is a kind of hybrid mode.

There's more liquid nitrogen ahead The day before yesterday, overclocker Sampson managed to overclock the 96-core Ryzen Threadripper PRO 7995WX to 4.8 GHz for all cores using air CO and setting many records, and yesterday he set new records by overclocking the same CPU using a liquid cooling system. [caption id="attachment_83316" align="aligncenter" width="780"] Ryzen Threadripper PRO 7995WX[/caption] Ryzen Threadripper PRO 7995WX overclocked using liquid CO The CO was created from a HeatKiller IV processor unit, a ThermalTake radiator and an Enermax pump. This allowed us to increase the frequency of all cores to 5.265 GHz! This was the maximum frequency without any load and with a consumption of about 600 W. In applications like Cinebench, the processor clocked at about 5 GHz, while consuming up to 1 kW of power! Of course, all this allowed us to set new records. For example, 167,309 points in Cinebench R23. But in the near future we should definitely expect new achievements when the Threadripper PRO 7995WX is overclocked using liquid nitrogen.

This is the price of a barebone kit, but a completely finished PC turned out to be cheap The Minisforum company has apparently released one of the most affordable mini-PCs based on a fairly powerful processor, and not on Intel “atomic” CPUs.  [caption id="attachment_80797" align="aligncenter" width="780"] Minisforum UM480XT[/caption] Priced under $200, the UM480XT mini PC is powered by the Ryzen 7 4800H. Yes, this is far from a new processor, it was released in 2020 and is based on the Zen 2 architecture, but it has eight full-fledged cores, a 7 nm process technology and a very productive iGPU even by modern standards, although it falls far short of the Radeon 680M/780M .   Full eight Ryzen 7 cores and a decent iGPU in a mini PC for just $190. Minisforum UM480XT introduced It is worth saying that for $190 the manufacturer only offers a Barebone kit, but this is still a price segment where much less productive solutions are often presented. In addition, a fully built PC with 16 GB of RAM and a 512 GB SSD will still be very cheap: only $250.  As for the rest, you can allocate space for installing a 2.5-inch drive, a high-performance cooling system, Wi-Fi and Bluetooth adapters, as well as a very good set of ports: two USB-C, two HDMI, a pair of USB 2.0, a pair of USB 3.2 Gen2 and RJ45.   The dimensions of the new product are 128 x 128 x 48 mm.  

Demand is still outpacing supply While communicating with Weibo users, Lei Jun, head of Xiaomi, said that the sales volume of the Xiaomi 14 series has already exceeded one million units, and also confirmed that demand is far outpacing supply. As they say, “this has never happened before, and here it is again.” Before the announcement of Xiaomi 14, the company stated that it had taken into account its past mistakes, making excellent preparations for the launch of Xiaomi 14, and also adding that there would be enough smartphones for everyone. [caption id="attachment_80471" align="aligncenter" width="780"] Xiaomi 14[/caption] More than a million Xiaomi 14 have already been sold “It is true that the number of Xiaomi 14 units sold has exceeded one million smartphones, but the shortage is still serious. We are desperately asking suppliers to increase supplies. Please be patient,” Lei Jun said. Just 5 minutes after the Xiaomi 14 went on sale, the new product improved the previous generation's result for the entire day by 600%, and also topped the sales charts of JD.com, Tmall, Douyin and Kuaishou. Lei Jun added that the Xiaomi 14 series has made a historic leap: “The Xiaomi 14 series is our success. I believe that Xiaomi mobile phones will get better and better." The editor-in-chief of the Mobiltelefon portal Evgeniy Makarov reported problems with the Xiaomi 14 camera in his personal Telegram channel .
