Despite nearly empty pavilions at this year's Computex 2022 in Taipei, journalists from TechPowerUp found a curious booth from Chinese company Wii Power (no relation to Nintendo), which showed off several gallium nitride (GaN) cell-based chargers.Image source: techpowerup.comGaN-cell chargers offer high power at a fairly modest physical size, and the technology promises to dominate the market in the coming years.The most powerful charger in the range of the Chinese manufacturer was 340W - these have not yet been on the market.It is presumably a pre-production prototype, besides it is rather bulky - 150 × 86 × 34 mm, though this is excusable if you consider that it outputs up to 17 A at 20 V.The device is equipped with a USB Type-C port with USB PD support and a set of other connectors that deliver up to 45 watts.Another charger has output power up to 240 watts, but offers more interesting connectivity options.The first USB Type-C port has 140 watts and the second port has 100 watts.Then you can connect both cables to the adapter and get all the available 240 watts at the output.And adapters are available for different laptops.There is also a third USB Type-C port and a USB Type-A connector for connecting less power-hungry consumers like smartphones.There is also a built-in display on board, which displays voltage, current and power readings.The device is also quite bulky (130 × 80 × 32 mm), but not for its capabilities.Finally, it is worth noting and the third exhibition sample - a compact charger rated at 140W (28V, 5A), which will be convenient to take with you on the road.It is unlikely that any of these chargers will be at retail in the near future, but in the somewhat more distant future with the spread of GaN technology the number of such offers will definitely grow.
Biostar shows X670E Valkyrie board for Ryzen 7000 processors
Biostar has shown the X670E Valkyrie motherboard at Computex 2022 based on the flagship AMD X670E chipset.New motherboard is designed for upcoming Ryzen 7000 (Raphael) processors.Image source: BiostarThe manufacturer has not yet disclosed all the technical specifications of the X670E Valkyrie board.The novelty is equipped with two slots PCIe 5.0 x16.However, when you install two graphics cards the number of dedicated PCIe lines are divided in half between them, both slots will operate in x8 mode.There is also a third slot PCIe 4.0 x16.The novelty received four M.2 slots for SSDs, but how many of them support PCIe 5.0 is not specified.At least the uppermost one must comply with the new standard.There is also one M.2 Key-E slot for Wi-Fi/Bluetooth module. It is also supposed to have 2.5 Gbps network adapter, HDMI and DisplayPort connectors, six SATA III ports, two USB Type-C Gen 3.2 2x2 (one front, one rear), as well as Realtek audio codec and a couple of connectors for ARGB-lighting.Interestingly enough Biostar is the only motherboard manufacturer who announced at Computex 2022 which announced what frequency of data transfer speeds its product would support.The X670E Valkyrie model allows you to install four DDR5-5600 RAM modules.However, it should be remembered that AMD AM5 platform can support even higher speed RAM modules.For example, AMD held its presentation using DDR5-6000 and even DDR5-6400 memory.

ASUS has shown a futuristic PC concept with almost no wires
Following Gigabyte and MSI, ASUS has decided to show at Computex 2022 its vision of a PC with no power cables visible.Only unlike the first two, which decided to hide the cables as much as possible, ASUS showed a prototype computer that has no cables at all.Almost.Image source: ASUSWhen you first look at the ASUS ROG Avalon computer, you might confuse it with a NAS, or at best a passively cooled HTPC.But both of those assumptions are wrong.A closer look reveals that this is one of the most sophisticated computer system designs ever.The radiators on the sides of the system unit case are actually air vents.On the left side of the ROG Avalon is a full-sized graphics card, which is probably the only item in this build that requires a power cable, unless you count the raiser adapter that connects it to the motherboard.What's hiding in the other side of the case - ASUS does not tell.However, the case itself has been developed in cooperation with InWin.The motherboard in this computer is completely custom.It is about the size of a Mini-ITX.Only four slots for RAM, an M.2 slot and, by all appearances, an LGA 1700 Alder Lake CPU socket stick out of it.Numerous expansion boards are connected to the motherboard from the back side: one to connect the power supply, another board to connect four 2.5-inch drives, the third is the aforementioned raiser for the graphics card.All system components can be quickly and easily replaced.Rear panel of the system unit is also modular.It comes in three variants, named \"Home Theater\", \"Virtual Reality\" and \"Workstation\", which reflect their purpose.The power supply of the computer is made in SFX-format.However, instead of wires, it uses an interface that resembles PCIe.The power supply has a capacity of 600 watts.It can also be quickly replaced if needed without disassembling the whole system unit.The motherboard is also equipped with several connectors for ports on the front panel: two USB Type-C and a pair of 3.5mm audio outputs.There is also one M.2 slot for NVMe storage installation.Another one is also located on one of the expansion boards.Also on the back side of the board you can see the usual power connectors of the board and the processor, and also there is a PCIe x16 slot.ASUS computer concept is really interesting, but it is still unclear whether the company plans to turn it into a consumer product.
AMD said the Ryzen 7000 shown the other day reached 5.5GHz without manual overclocking
AMD's opening event at Computex 2022 included a demonstration of the Ryzen 7000 series Socket AM5 CPU in Ghostwire: Tokyo.An engineering sample of the 5nm processor reached frequencies of 5.2 to 5.5GHz \"across multiple cores\" using liquid cooling.The company claims that he was not forced overclocking.Image source: AMDIf the fact of using unattended liquid cooling system Asetek with radiator size 280 mm and two 140-mm fans was detected while studying AMD press release, the description of the number of active cores in these modes was made by Technical Marketing Director Robert Hallock (Robert Hallock) during an interview with PCWorld resource after the event, opening Computex 2022.The main questions were whether the additional, manual overclocking p The first question was answered in the negative by Robert Hallock, who said that the Ryzen 7000 sample CPU showed \"natural frequencies\" of 5.2 to 5.5 GHz in the mentioned game.By the way, it should be mentioned that AMD web page on Computex 2022 events shows the frequencies of Zen 4 processors in Max Boost mode more than 5.0 GHz.This implies that a single processor core is guaranteed to work in that range under the appropriate load nature.Returning to the topic of the number of active cores, Hallock added that frequencies from 5.2 to 5.5 GHz were reached by a significant portion of them, and at times all processor cores worked at some of the frequencies in that range.Much will depend on cooling conditions, the nature of the load, and the capabilities of the particular motherboard.To prepare for Computex 2022 demonstration, the company used some reference board based on AMD X670 chipset and two DDR5-6000 (CL30) RAM modules with 2 × 16 GB capacity.
MSI has confirmed support for AMD EXPO profiles for overclocking DDR5 memory on Ryzen 7000 systems
At Computex 2022, it was confirmed that AMD Ryzen 7000 processors will receive support for EXPO and Smart Access Storage technologies.The first technology has been previously reported.EXtended Profiles for Overclocking or EXPO is an analogue of Intel XMP 3.0 automatic overclocking profiles to increase the frequency of DDR5 RAM.Image source: VideoCardz / MSIAMD said that Smart Access Storage technology will be based on the already well-known Microsoft DirectStorage, which is used in Xbox Series game consoles and accelerates the loading of games.As noted by the company, the traditional game download scheme involves the participation of the CPU in the unpacking of game data and its movement, which increases the delay and requires a lot of CPU resources.Smart Access Storage will redirect the unpacking of game data to the GPU, bypassing the CPU, which will accelerate the loading of game levels and textures.Note that SAS which will not only rely on Microsoft DirectStorage, but also technology Smart Access Memory (SAM), which provides processor access to the entire memory of the graphics gas pedal.Image source: AMDAmd did not touch the topic of overclocking memory profiles EXPO, so the exact details about it yet unknown.However, the company used overclocked DDR5-6000 memory modules during the presentation of the Ryzen 7000 processor series. Source image: MSIThe EXPO technology was mentioned in MSI promo slides, which the company prepared to announce its motherboard based on chipset AMD X670.Another interesting feature of MSI promo slide is an indication that Socket AM5 platform supports 28 lanes of PCIe 5.0 instead of 24 lanes as AMD itself said during its presentation.It is possible that one of the manufacturers could have made a mistake.However, it is also possible that these four additional lines will be available for the next generation of Ryzen processors within the Socket AM5 platform, for example, for Ryzen 8000 conditional chips.Another interesting topic of discussion is the claimed TDP value of 170 W for the older Ryzen 7000 models.AMD has confirmed that this refers not to the nominal power consumption of the chip, but to the Peak Package Tracing (PPT) power value of the entire processor package.In other words, we're talking about the CPU's maximum power consumption during heavy loads.The actual TDP rating of the older Ryzen 7000 processor models is likely to be 105-125W.However, AMD does not specify this point.Still, the aforementioned MSI promotional slide clearly indicates exactly the TDP figure.If we're talking about TDP value, it is higher than current Ryzen 5000 processor's value of 142 W.VideoCardz says that MSI has asked the media not to publish the above slide.The manufacturer did not specify the reason.Perhaps because it indicates the EXPO technology, or maybe because it contains incorrect data.
