Arm stopped selling licenses to Chinese companies for advanced processor architectures
Chinese processor developers are making serious bets on Arm and RISC architectures, since access to them has so far not been restricted by political opponents.But now Arm has refused to export Neoverse V architecture licenses to China and this could become a nasty precedent, limiting the pace of development of China's national semiconductor industry.Image source: AlibabaBritish Arm holding, as the Financial Times reports, has determined that Chinese customers cannot buy licenses to use Neoverse V processor architectures because they allow processors to be built at performance levels that exceed the values allowed by US export rules.The Neoverse V architecture includes elements developed in the United States, so British Arm has to negotiate the nuances of exporting the relevant technology with overseas officials.As expected, the Chinese giant Alibaba as a result of such restrictions may face the inability to use the Neoverse V1 or V2 architecture in its processors.In this case, the Chinese partners of Arm will be available architecture series Neoverse N2, which has a lower speed.This situation resonates with the restrictions, which have already faced NVIDIA, which lost the right to supply after the fall of next year, gas pedals generation calculations Ampere and Hopper with a certain level of performance.The supplier was quick to react and started offering Chinese customers special A800 gas pedals, whose performance avoided the sanctions restrictions by a margin.Arm's Chinese customers found themselves in a similar situation.The same company, Alibaba, expected to buy a license from Arm to use the Neoverse V1 architecture to develop processors used in cloud systems.Competitor Amazon Web Services in the U.S.already uses the architecture of this series to create specialized processors used in its own infrastructure.Alibaba representatives, on condition of anonymity, expressed dissatisfaction with Arm's behavior, stating its reluctance to sell technology to China even if such deals are adequately funded.

Core i9-13900K review: 350 Watt unit (not really)
Intel has long ago abandoned the \"tick-tock\" approach in development, but nevertheless, its echoes can still be caught when the company launches new products.For example, the Alder Lake, which didn't quite fit this principle and introduced both a new process technology and a new architecture at once, was replaced by the new generation of Raptor Lake, which has clear signs of an intermediate technological step \"optimization\".This stage became a popular method of processor improvement in the times of Skylake architecture domination and Intel doesn't give it up even today.But there is an important difference: now the optimization steps are related not so much to the desire to maximize the lifecycle of old designs, as to increase the pace of CPU generation change.Raptor Lake is already the third family of Intel desktop processors since the beginning of 2021, and it would be strange to expect from it any dramatic innovations.At the same time, Raptor Lake is a far cry from the kind of \"optimization\" the company resorted to when getting Coffee Lake and Comet Lake from Kaby Lake.This time Intel's approach is much more thorough, and Raptor Lake isn't just Alder Lake with extra processing cores. For one thing, Raptor Lake does inherit all the main features of Alder Lake.It's a hybrid processor based on the same principles, built with performance and power-efficient cores with the same microarchitecture as before.What's more, it's designed for the LGA1700 ecosystem and is fully compatible with older motherboards and supports both DDR5 and DDR4 memory.On the other hand, Raptor Lake has a significant increase in clock speeds, which is due to improvements in the Intel 7 process technology.In addition, the new processor has received a doubled number of E-core and, in addition, all of its cores have increased the amount of cache memory on Level 2.Thus, although Raptor Lake can not be called a full-scale upgrade, it has a sufficient set of advantages for both low- and multi-threaded loads.And that means that from a user perspective, Raptor Lake should be better than Alder Lake literally everywhere: in resource-intensive content creation and processing applications as well as in gaming workloads.How significant these improvements are from a practical point of view, and we will analyze in this article.⇡#Performance and energy-efficient cores Raptor LakeStarting the search for deep differences between Raptor Lake and Alder Lake, it is worth clarifying that they are produced by the same Intel 7 process technology, that is 10-nm norms (the full name of the technology process - 10 nm Enhanced SuperFin).Moreover, the cores underlying Raptor Lake, too, can not be called new: it's not even a redesign, but rather what is called the word \"refresh\".In fact, all internal improvements in the new CPU affect only cache memory and DDR4/DDR5 controller, but do not touch other functional blocks.In this sense, Raptor Lake could not even be called a new code name, but simply Alder Lake 2.0.However, in the absence of explicit microarchitectural changes, the performance cores of Raptor Lake compared to Golden Cove cores of Alder Lake processors have received a much higher clock speed.And this is due to evolutionary improvements in the manufacturing process.While the lithography resolution hasn't changed, Raptor Lake uses an optimized version of Intel's 3rd generation SuperFin transistors with reduced channel resistance.This allowed Intel engineers to reconsider the dependence of core frequency on their voltage and eventually achieve an increase in clock speeds without a noticeable increase in power supply voltage.In describing the new relationship, Intel points out that at equal frequency, Raptor Lake can use 50 mV less voltage than Alder Lake, and at equal voltage its frequency can be 200 MHz higher. Combining these improvements, engineers were able to push the maximum frequency of Raptor Lake's performance cores to 5.8 GHz, 600 MHz more than the frequency limit of Alder Lake! The optimized processor not only enabled higher frequencies, but also increased the transistor budget that was used to increase the number of cores.While the Alder Lake chip contained eight performance and eight power-efficient cores, Raptor Lake doubled the number of power-efficient cores.In other words, without changing technology norms, Intel made the first civilian processors with 24 cores (16 of which are energy efficient). However, all this did not go unnoticed for power consumption and heat dissipation.While the thermal package of the senior Raptor Lake remained at 125W, the limit of their maximum power consumption had to be pushed to 253W.And that means
Bloggers and media showed unboxing Radeon RX 7900 XTX and RX 7900 XT - reviews will appear on December 12
AMD allowed core media and tech bloggers to publish materials with unboxing of the latest graphics cards Radeon RX 7900 XTX and RX 7900 XT, reports VideoCardz.However, reviewers can not publish information about their performance or reviews - it will have to wait until next week.Image source: VideoCardzThe majority of reviewers got their hands on a reference version of the Radeon RX 7900 XT and Radeon RX 7900 XTX.While at first glance the two cards don't seem to differ from each other, a closer look reveals that this is not the case.The flagship Radeon RX 7900 XTX is slightly taller and longer than the Radeon RX 7900 XT.In addition, the video cards have a different RGB backlight configuration.However, both benchmark gas pedals have the same thickness of two expansion slots.In addition, both video cards received two 8-pin connectors for additional power. Image source: Overclock3DIt is also known that Radeon RX 7900 XT and Radeon RX 7900 XTX use different circuit boards.The flagship model has a wider one.The older version uses a board marked D704, the younger one uses a board marked D702.It is obvious that apart from the size of the circuit boards the graphics cards also differ in their VRM power subsystems.However, more detailed information on this will be known after the novelties will be available for disassembly. Image source: TechPowerUpDirect comparison shows that the next-generation Radeon graphics cards are much more compact than the reference models GeForce RTX 4090 and GeForce RTX 4080, which themselves are considered compact solutions in the new series of NVIDIA gas pedals compared to non-reference versions. Image source: ComputerBaseIt is curious that among the media only one source has received a non-reference model of AMD graphics cards on the RDNA 3 architecture.British publication Overclock3D has shared a picture of XFX Radeon RX 7900 XTX MERC 310, images of which flashed quite recently. Source image: Overclock3DThe German edition HardwareLUXX, full independent reviews of the Radeon RX 7900 XT and Radeon RX 7900 XTX will begin to appear on December 12, the day before the actual start of new products.Recall that in the benchmark flagship Radeon RX 7900 XTX estimated at $ 999, the junior Radeon RX 7900 XT has a price tag of $ 899.The first uses a full-fledged GPU Navi 31 with 6144 stream processors and is equipped with 24 GB of GDDR6 memory.The second one is based on a \"cut down\" Navi 31 GPU with 5376 stream processors and 20 GB of GDDR6 memory.

The full specifications of the Core i9-13900KS 6GHz chip were revealed, and it was also up to 39% faster than its predecessor
As part of the Raptor Lake desktop processor announcement, Intel has confirmed that it plans to eventually release another flagship processor capable of automatically overclocking to 6GHz right out of the box.Officially, the manufacturer did not disclose the name of this model, but apparently it was about Core i9-13900KS.The latest major leak about Intel chips confirmed these assumptions and revealed the full specifications of the upcoming select CPU.Image source: VideoCardzCore i9-13900KS is a 24-core processor, which includes eight efficient P-core and 16 energy-efficient E-core.The processor supports 32 threads.Turbo Boost Max 3.0 technology allows its 1-2 highest performing cores to automatically overclock to 5.8 GHz.Thermal Velocity Boost technology provides an extra 200 MHz of automatic overclocking to the same 6GHz.The base frequency of the Core i9-13900KS large cores is also 200 MHz higher than the regular Core i9-13900K, at 3.2 GHz.At the same time, the power-efficient cores of the KS version operate in the same frequency range - from 2.2 to 4.3 GHz. Image source: Twitter / @9550proThe Core i9-13900KS rated power consumption increased from 125W to 150W.However, the maximum power consumption has not changed and stands at 253W.The chip supports the same memory standards as all other Raptor Lake processor models - DDR4-3200 and DDR5-5600.Shortly after the above leak, the first data about Core i9-13900KS performance in synthetic Geekbench test also appeared on the web.The processor was tested with ASUS ROG Z790 Maximus Hero motherboard and 32 GB DDR5-7200 RAM. Image source: GeekbenchDetailed telemetry data from three Geekbench tests indicate that the Core i9-13900KS automatically overclocked on multiple cores to 5893 MHz, but its average clock speed was 5867 MHz.Image source: GeekbenchIn the single-core performance test the processor scored up to 2319 points, and in the multi-core performance test it scored up to 26,774.So, on average, its single-core performance is 10% better than its predecessor Core i9-12900KS (Alder Lake), and multi-core performance is 39% better.Image source: Geekbanksh Image source: VideoCardzThe Core i9-13900KS is expected to be officially launched in early January, at CES 2023.It should go on sale during the first quarter of next year.
Next year the desktop market will almost stop falling
Not the easiest year for the computer market is coming to an end, so DigiTimes Research experts have shared their forecasts for next year and summed up the current one.The latest one for the desktop market, according to the authors of the study, was not as bad as the one for laptops.The supply of mobile PCs fell by 20%, and desktop PCs fell by only 11%.Next year, the decline in the desktop market will be limited to 2.1%.Image source: AppleAccording to the source, during the three quarters of this year, the corporate sector supported the demand for desktop systems, and only in the fourth quarter should the volume of their shipments consistently fall by 11.7%.Most manufacturers have accumulated impressive inventories in their warehouses, so they are in no hurry to deliver new products to customers.For all of 2022, DigiTimes Research predicts that 86.4 million desktops will be delivered globally in finished form.That's 10.9 percent less than the results for 2019, which is taken as a base for comparison because of the lack of a pandemic factor.Next year, no more than 84.6 million desktops will be delivered to the market, a decline of 2.1% from this year.In the first quarter of the outgoing year, 21 million desktops were delivered, in the second quarter shipments peaked at 24.3 million units, but in the third has already dropped to 22 million.They are expected to fall to 19.2 million units in the fourth quarter.Almost 13% of the segment is comprised of all-in-one, one-piece computers.By the end of the year 11.06 million units should be delivered.The peak of popularity of such PCs reached in 2021, when 14.32 million units were sold.For this reason this year the number of monoblocks shipped on the market will decrease by 22%.The largest contract manufacturer of monoblocks previously was Quanta Computer, which serves the interests of Apple, but at the end of the year it dropped to the third place.Compal and its main client Lenovo is on the second place, and the first this year will go to HP Inc.Wistron, which produces monoblocks for Dell, will be in fourth place.The three Taiwanese contract manufacturers together control 72% of the market.Next year, shipments of desktop monoblocks could grow by several percent, according to DigiTimes Research analysts.In their view, a return to growth in demand for Apple iMacs should contribute to this.
TSMC feels no downturn in the market - November revenue soared 50.2 percent
TSMC management was optimistic this week about its prospects for contract manufacturing of semiconductor components for US customers, as its budget for building two facilities in Arizona reached $40 billion and its design capacity was tripled.On a global scale the company also feels good because its November revenue grew by 50.2% compared to the previous year.Image source: TSMCIn accordance with the statistics published by TSMC in November the company made about $7.3 billion in current exchange rates, and this corresponds to the sequential growth of 5.9%, and in annual terms the revenue jumped by 50.2%.We can not hesitate to call this year a period of significant growth for TSMC, because from January to November the company's revenue grew by 44.6% to $67.6 billion.For not the easiest year in terms of geopolitics the dynamics is very decent.Let us not forget, however, that not everything is cloudy in TSMC activities.The amount of capital spending for the current year, it still had to reduce from $40 to $36 billion.At the last quarterly event the company representatives also complained about the decline in demand for products used in the PC and smartphone segments, some of which are produced on an advanced 7-nm process.By the middle of next year, the company expects to regain the utilization rate of the respective production lines.The company also has to postpone the modernization of its facilities due to delays in the supply of lithographic equipment.
