A few words about energy-efficient processors AMD Van Gogh / News / Overclockers.ua

A new piece of information about AMD Van Gogh ultra-low power 6-15 W APUs has appeared on the Web. These chips will find use in ultrabooks or other compact technology and should be presented by the end of 2021.

Van Gogh

The Van Gogh family will use two key AMD technologies: Zen 2 for the processor and RDNA 2 for graphics. It is believed that the design will be different from all previous APUs, but retain the monolithic construction of the Renoir or Cezanne. The Van Gogh chips will have a BGA FF3 design and will be manufactured using a 7nm process technology.

Van Gogh

Van Gogh APUs have four AMD Zen 2 cores. In general, the die area should be as small as possible, which, among other things, will be achieved by reducing L2 and L3 caches. No information has been received regarding dual-core models. But AMD is striving to make the most of the rejected chips to expand the product line downward, so their exit is not excluded.

Unofficial AMD Processor Roadmap

There is no data yet regarding the RDNA 2 graphics unit. The number of computational modules for senior models will not exceed 8-10 CU (up to 512-640 stream processors). Despite the new architecture, you should not expect miracles in iGPU performance, as the low TPP will not allow you to reach high frequencies.

A month ago, there was a rumor about a 256-bit (or four-channel) DDR5 memory controller from Van Gogh. According to Moore’s Law is Dead, this is not true, because this decision will lead to an increase in the cost and complexity of the chip, while AMD, on the contrary, is moving towards simplification and reduction of the area. Van Gogh is much more likely to rely on LPDDR5 memory.

Netac develops 10 GHz DDR5 RAM

Chinese firm Netac has confirmed the research and development of DDR5 memory that will be able to operate at an effective frequency of 10 GHz. For the first DDR5 batches, this figure will be at least 4800 MHz (this value is mentioned in the specifications of Intel Alder Lake processors), but the roadmaps list the range up to 8400 MHz. As for DDR5-10000, such modes are extreme and require at least manual overclocking or a tuned XMP profile.

Netac

Netac has been on the RAM market recently – since 2018. To date, their portfolio includes not only mainstream RAM products, but also gaming sets, including DDR4 with RGB backlighting. As for the new standard, Netac has already received the first batches of the Micron DDR5 chip labeled IFA45 Z9ZSB. Initially, the modules will operate in DDR5-4800 mode with CL40-40-40 delays, according to the JEDEC standard.

Micron DDR5

As we know, the release of the first Intel LGA1700 platform and CPU Alder Lake with DDR5 support will take place in the second half of this year. AMD should release a response in the form of Socket AM5 and Zen 4 processors, but that will likely only happen next year.

Microsoft’s Surface Laptop 4 is really twice as fast

We expected that AMD’s Zen 2 powered Ryzen chips in the Surface Laptop 4 would be superior to the Surface Laptop 3. But so much? […]

This article is just a glimpse of how the Surface Laptop 4 performed on a limited number of benchmarks before our full review comes out (c) Microsoft

Microsoft unveiled the Surface Laptop 4 on Tuesday with some bold performance claims: The Surface Laptop 4 is said to outperform the Surface Laptop 3 by around 70 percent, and in certain scenarios even offer twice the performance.

Does it live up to the hype? Does it ever do that? Although the difference between the two generations of Surface Laptops becomes smaller in everyday activities, our early tests show that the Surface Laptop 4 wins all CPU-intensive tasks by a wide margin. (If you’ve been keeping an eye on Microsoft’s offer of a free pair of Surface Earbuds for every Surface Laptop 4 preordered by April 15th, this could be an incentive).

Dispatched April 27th

Microsoft will begin shipping the Surface Laptop 4 in Europe on April 27th in two traditional display sizes: 13.5-inch and 15-inch. Inside you have the choice between two microprocessors: either the 11th generation core chip (Tiger Lake) from Intel or the Surface Edition processor, which was jointly developed by Microsoft and AMD, and on AMD’s mobile Ryzen 4000 CPUs (Zen-2 architecture) is based. While the Intel CPUs are off the shelf, the Surface Edition processors are highly clocked parts that cannot be found in any other notebook in the world.

We received a 15-inch version of the Surface Laptop 4 in which the eight-core Ryzen 7 4980U Surface Edition is installed. The operating system reports it as a 2 GHz chip, with boost speeds that (according to the CPU-Z utility) don’t seem to go higher than 4 GHz.

This article is just a glimpse of how the Surface Laptop 4 performed on a limited number of benchmarks before our full review appears. You may notice slight differences from the numbers we ultimately publish in our review as we typically run multiple instances of each benchmark to ensure accuracy. We haven’t run any battery life tests either.

We’re also artificially narrowing the scope of this performance preview to show how the Surface Laptop 4 compares to the various iterations of the Surface Laptop 3 and other Microsoft devices. Our next review of the Surface Laptop 4 will include competing third-party notebooks to show how it compares to a broader field.

Surface Laptop 4: Early Performance Benchmarks

UL’s PCMark 10 measures everything from how your laptop is performing in a video chat, to word processing and spreadsheets, photo editing and rendering, to light gaming. There is hardly a generation difference in these everyday tasks: The Surface Laptop is 4 to 6 percent ahead of the fastest Surface Laptop 3.

In day-to-day work, as measured by PCMark, it seems that there isn’t much of a difference between the Surface Laptop 4 and the Surface Laptop 3 (c) Mark Hachman / IDG

Since CPU performance is so critical to everyday laptop performance, we’ll test it in two ways. Maxon’s Cinebench offers a simple, comparative metric for evaluating laptops, desktops and individual processors. Here the Surface Laptop 4 offers a little more than double (104 percent) the CPU performance of the fastest Surface Laptop 3.

Remember how Microsoft claimed that the Surface Laptop 4 could be twice as fast as the Surface Laptop 3? The combination of more and faster cores makes this a reality on a large scale (c) Mark Hachman / IDG

HandBrake, an open source utility, represents our other CPU test by putting an extended load on the laptop – dubbing a full-length, high-definition Hollywood movie into a format that is safe to store on an Android tablet suitable is. This process can take more than an hour with older hardware. How well can the Surface Laptop 4 handle full power over a long period of time? How well did Microsoft engineers design the Surface Laptop 4’s cooling solutions so that it doesn’t throttle to maintain stability? HandBrake tells us: very good!

With HandBrake, the Surface Laptop 4 does the job in about half the time (49 percent) that the Surface Laptop 3 takes.

In the real HandBrake test, the Surface Laptop 4 again offers about twice as much performance as its predecessor (c) Mark Hachman / IDG

In our performance test, we use UL’s other benchmark, 3DMark, to assess graphics performance. The Surface Edition processor offers integrated graphics instead of a discrete GPU. The Surface Laptop 4 shows a more modest increase in graphics performance of 33 percent compared to the similarly equipped Surface Laptop 3. (The benchmark crashed when running on the Surface Laptop 1 and Surface Laptop 2, which is why the results are not shown for these models).

The 3DMark score was a bit of a surprise. Intel’s integrated Xe GPU continues to impress, which leads us to believe that the 11th-gen-core version of the Surface Laptop 4 will be the fastest in terms of graphics (c) Mark Hachman

As the picture (and the Surface Pro 7+ score) suggests, the Surface Laptop 4 with the strongest graphics will likely be the Intel Core-based version with the built-in Xe GPU. We hope to be able to test this version of the Surface Laptop 4 shortly.

Conclusion: A strong start for the Surface Laptop 4

These preliminary benchmarks give some very positive indications of the latest Microsoft Ryzen 7 4980U Surface Edition processor powering the Surface Laptop 4. Many questions remain unanswered, especially the all-important battery life. We also didn’t look closely at whether the Surface Laptop 4 throttled its CPU or GPU under different loads. We haven’t received an Intel-based Surface Laptop 4 to test either – how well will that work? Last but not least, we of course also have to evaluate the display quality, keyboard and trackpad performance, connectivity and other properties of the Surface Laptop 4.

We’ll answer all of these questions and more in our official review. In the meantime, we have this strong indicator: twice as fast as the Surface Laptop 3. Twice as fast. In most benchmarks, Microsoft’s Ryzen-powered Surface Laptop 4 does what it says it is.

Alphacool NexXxoS UT60 Nova 1080 LSS Radiator Supports Nine 120mm Fans

The German firm Alphacool has unveiled four large radiators for uncompromising water cooling. All major parts of the new products are made of copper, including heat exchange chambers, channels and fins. Only mounting plates and elements of the radiator frame are made of steel, threaded connections are made of brass.

Alphacool NexXxoS

Radiators NexXxoS Monsta 200 mm (price from 85 euros) and Monsta 400 mm (from € 116) are designed for fans with a standard size of 180 mm or 200 mm and have a thickness of 86 mm. Both products have seven standard G1 / 4 holes. Six of them are used to connect hoses, and the seventh port is located in the end chamber and can only be used for filling, draining or venting the system.

Alphacool NexXxoS

The density of the fins is 12 FPI, which allows the use of fans with lower static pressure and lower speed.

Alphacool NexXxoS

NexXxoS UT60 Nova 1080 mm (price from 138 euros) is one of the most efficient radiators in CBO. The huge cooling surface is comparable to three standard 360mm radiators and requires nine 120mm fans per kit.

Alphacool NexXxoS

This makes it easy to dissipate more than 1000 watts of excess heat using extremely quiet or silent Carlsons. For example, this amount of heat is equivalent to one 64-core AMD Threadripper 3000 and at least two GeForce RTX 3090 graphics cards.

Alphacool NexXxoS

NexXxoS XT45 Quad 480/560 mm (price from 90 euros) is a junior version of the UT60 Nova 1080 mm. It comes with two mounting plates, each of which can accommodate four 120mm or 140mm fans.

Alphacool NexXxoS

The novelty corresponds to the cooling capacity of two 240/280 mm radiators. NexXxoS XT45 Quad 480/560 mm is capable of meeting the needs of any desktop system with one processor and one graphics card.

Alphacool NexXxoS

Alphacool also introduced Apex Liquid ECO, which is “environmentally friendly and easy to dispose of”. Purified water is the basis, and additional additives have an antibacterial effect and reduce the surface tension of the coolant, which facilitates the elimination of bubbles in the circuit.

the industry faced a shortage of network routers / News / Overclockers.ua

Internet providers have been facing delays in the supply of new routers for more than a year due to a global shortage of chips, according to Bloomberg. According to people familiar with the issue, the lead time for orders reaches 60 weeks, which is more than double the previous values.

ASUS RT-AX55

According to Karsten Geveke, head of the European regional division of Zyxel Communications Corp, the abrupt cessation of production a year ago due to the coronavirus was exacerbated by an unprecedented surge in demand for broadband equipment and other electronics due to the transfer of employees to remote work, and students and students to distance learning.

Since January, Zyxel has been asking customers to order products a year in advance because lead times for components such as Broadcom chips have doubled. However, there is another side to the coin: over the past twelve months, Zyxel shares are up more than 181%.

US networking equipment maker Adtran has also warned customers about supply chain risks and extended delivery times in recent months. A company spokesman said the company has expanded its UK warehouse space, more than doubling its inventory and logistics capacity to avoid problems. The container ship Ever Given also played a role in the supply crisis, blocking the Suez Canal for a week.

By the way, the situation with routers can directly affect the Ukrainian market. Networked devices have lower margins than smartphones or computers. In turn, products for less affluent markets such as Eastern Europe use simple electronic components with even lower margins. Obviously, less profitable work is relegated to the background. Therefore, in this situation, small telecom operators or consumers in the countries of the second or third world will suffer the most.
