Normally CPU performance increases with newer generations but, according to a new leak, the upcoming Intel chips may be going against the grain.

A new leak reveals that the Intel Arrow Lake desktop lineup may have a clock speed of up to 5.5 GHz, much lower than its current flagship Intel Core i9-14900KS which can reach up to 6.20 GHz, according to tech leaker MebiuW on Weibo (reported on by Wccftech). Apparently, the upcoming flagship Core 9 Ultra 285K could face a potential drop of 700MHz compared to its predecessor, which is rather large.

Of course, if Intel’s architectural improvements are large enough, then clock speed may not be nearly as important as in past generations. But MebiuW has a response to that proposal and it doesn’t look good for Intel if true. It seems that the single-core performance of the 285K might not be greater than 12% of the 14900KS’s. In other words, while the former might be a little faster, it won’t be by much.

Why this could be a good decision

Intel has been struggling to compete with AMD for having the best processors for gaming. There have been widespread reports of 13th and 14th-Gen Core i9 CPUs crashing while playing games, and in some cases even refusing to boot up Windows 11. In response, the manufacturer has asked motherboard makers to limit power settings to reduce energy consumption.

Intel usually relies on its processors’ fast clock speeds to give them the performance edge against AMD’s. But If the leaks concerning the Intel Arrow Lake end up being true (which it hasn’t been confirmed by Intel in any official capacity yet), then the manufacturer lowering clock speeds on its chips could be directly related to this issue.

Team Red has already demonstrated that clock speeds aren’t necessary for solid gaming performance, as the Ryzen 7 7800X3D is incredibly fast in its own right thanks to its large stack of L3 cache. So this easily could be a case of Team Blue taking a page from its competitor’s book while preventing the same mistakes plaguing current and last-gen chips from repeating itself in the new gen.

Leaked plans reveal Intel could release 21 Arrow Lake-S CPUs this year

No Comments on Leaked plans reveal Intel could release 21 Arrow Lake-S CPUs this year

[ad_1]

Intel Arrow Lake appears to be on the horizon according to new insider information which claims a total of 21 CPUs will be available in the upcoming lineup.

As spotted by Wccftech, Intel Arrow Lake-S Core Ultra-200 processors are rumored to be announced at Computex next month with a full suite of processors headed for store shelves this year. According to Benchlife, this is set to include the Core Ultra 9 285K, Core Ultra 7 265K, and the Core Ultra 5 245K.

Interestingly, it’s believed that there will be no Core Ultra 3 or Core i3 equivalent included in the slew of Ultra 200 processors so the mainstream lineups are now considered to be Ultra 5 models. That’s not entirely a surprise given that even the best processors for gamers on a budget omit the underpowered i3.

It is believed that as well as the three aforementioned K models at 12W5, there will be a total of five non-K SKUs at 65W and a total of 13 processors set to release later which will run at just 35W. That’s a wide net and should give options to the vast majority of users; while gamers will want a K model, budget builds could benefit from a lower power, and cheaper chip.

Hyperthreading appears to be a thing of the past with the leading Intel Arrow Lake-S models. That’s because the Core Ultra 9 is speculated to run 24 cores and 24 threads with the Core Ultra 7 to feature 20 cores and 20 threads, and the Core Ultra 5 at 10 cores and 10 threads; all of which utilize a mixture of E-cores and P-cores.

All chipsets will run on the LGA 1851 socket with its longevity planned until 2026 which, much like AMD‘s AM5 socket, will just be using DDR5. That means it could be time to upgrade to some of the best RAM alongside a new motherboard so that you aren’t left behind.

It’s still a little confusing

We’ve previously reported on the Intel Arrow Lake-S naming conventions being confusing and the advent of so many Ultra 9, Ultra 7, and Ultra 5 models isn’t helping matters. While enthusiasts are going to want to stick to the 285K, 265K, and 245K, there are a lot of things to unlearn after nearly 16 years of being used to Intel Core branding.

It remains to be seen exactly how disaggregated architecture will work when on desktops, especially with the transition over to AI computing and what that will mean for gamers. We’re hoping that Computex will clear things up with an official announcement going over the full flagship models and the other 65W variants.

Intel Core Ultra 200 Arrow Lake CPUs could be coming earlier than expected

An MSI overclocker has alleged that the upcoming Intel Arrow Lake processor could be coming as early as Q3 2024 which would be significantly ahead of what we’ve previously thought.

As reported by KitGuru, an MSI overclocker named Toppc has dropped hints about the MSI Dragon Event in Wuhan, China which is rumored to feature information on the “next” platform which is heavily speculated to be the socket LGA 1851 desktop processors – Arrow Lake-S (via Chiphell).

Previously, it’s been rumored that we would not see Intel Arrow Lake until 2025 so the news that the chipset generation could be coming in just a few months is certainly welcome news. This source also corroborates that the Core Ultra 9, Core Ultra 7, and Core Ultra 5 models will be exclusive to DDR5 RAM, as with AMD‘s AM5 socket.

In terms of what we can expect from the Intel Core Ultra 200 lineup, the flagship of the next-gen CPU generation is believed to be the Ultra 9 285K. According to Wccftech, it’s alleged that this top-end chipset will top out at 5.5 GHz which is down significantly from the 6 GHz of the Intel Core i9-14900K and the 6.2 GHz of the 14900KS.

For reference, that’s the same out-of-the-box speed as the Alder Lake flagship model, the 12900KS, which debuted over three years ago. With changes in architecture, going from socket 1700 (Hybrid) over to socket 1851 (Disaggregated), it seems as though Intel is prioritizing efficiency over raw power with its upcoming CPU generation.

A Q3 release date is possible, but unlikely

Q3 2024 is between July and September which means Intel Arrow Lake could debut anywhere from two to three months from now. Considering the rumors circulating pointing at an end-of-year or early 2025 release date, we’re leaning more towards a later rather than sooner release date, but the K variants could come first.

Toppc has been on the money with leaks and rumors in the past, most notably with the pre-release information surrounding socket AM5 AMD CPUs in 2022 (via Chiphell). That lends credence to the fact we may not be waiting as long, as MSI’s internal events could suggest an earlier release, but we aren’t convinced of a summer release date at this time.

It’s fair to say that things have been turbulent for Arrow Lake. Recently, the pre-release silicon has been available for sale illegally in China. Engineering samples are being sold for as little as $14, however, even if the hardware is in the fabrication process that doesn’t necessarily mean it will be ready for prime time within the next three months. We’ll be keeping you updated on all things Arrow Lake as they happen.

A US supercomputer with 8,000 Intel Xeon CPUs and 300TB of RAM is being auctioned — 160th most powerful computer in the world has some maintenance issues though and will cost thousands per day to run

[ad_1]

The Cheyenne supercomputer, based at the NCAR-Wyoming Supercomputing Center (NWSC) in Cheyenne, Wyoming, was ranked as the 20th most powerful computer in the world in 2016 – but now it’s up for sale through the US General Services Administration (GSA).

By November 2023, the 5.34-petaflops system’s ranking had slipped to 160th in the world, but it’s still a monster, able to carry out 5.34 quadrillion calculations per second. It has been put to a number of noteworthy purposes in the past, including studying weather phenomena and predicting natural disasters.

The Cheyenne Supercomputer is a monster installation made up of SGI ICE XA modules which comprises of 14 E-Cells, weighing 1,500 lbs each, and 28 water-cooled E-Racks. There are 8,064 Intel “Broadwell” Xeon processors (18-core 2.3GHz E5-2697v4) with a total count of 145,152 cores. In terms of memory, it has 313,344GB of DDR4-2400 ECC single-rank memory and 224 IB Switches. The supercomputer also comes with two air-cooled management racks, each featuring 26 1U servers.

“Repairable”

Howeer, potential buyers do need to be aware of a few issues. Firstly, the unit doesn’t come with fiber optic and CAT5/6 cabling, although the internal DAC cables within each cell are provided and will be “meticulously labeled and packaged in boxes”, and it comes with previously used PGW coolant fluid (around10 gallons per E-cell). It will need to be collected by a professional moving company and the purchaser “assumes responsibility for transferring the racks from the facility onto trucks using their equipment.”

A major red flag is that the supercomputer is worryingly listed as “repairable”. The auction page states “the system is currently experiencing maintenance limitations due to faulty quick disconnects causing water spray. Given the expense and downtime associated with rectifying this issue in the last six months of operation, it’s deemed more detrimental than the anticipated failure rate of compute nodes.

Approximately 1% of nodes experienced failure during this period, primarily attributed to DIMMs with ECC errors, which will remain unrepaired. Additionally, the system will undergo coolant drainage.”

With a couple of days to go before the auction ends, bidding currently stands at $50,085 with the reserve not yet met. Should you wish to buy a piece of supercomputer history, and have the deep pockets required to get it up and running, and the space to house it, you can put in a bid here.

Intel’s next-gen CPUs might confuse you with their names – but whatever Arrow Lake is called, it’ll face a tough fight against AMD Zen 5

[ad_1]

Intel’s Arrow Lake processors are inbound for desktop PCs and should land later this year, and we’ve just caught a leak about how these chips might be named.

This comes from one of the more regular leakers on X (formerly Twitter), and as ever, sprinkle a whole lot of seasoning on the claims.

The theory from leaker Raichu (via VideoCardz) is that the first launches for Arrow Lake will be the 285K, 265K, and 245K – which should be the equivalent of the Core i9, Core i7 and Core i5 CPUs from the current-gen range (Raptor Lake Refresh).

So, the initial Arrow Lake CPU names could run as follows:

Core Ultra 9 285K
Core Ultra 7 265K
Core Ultra 5 245K

After that, the non-K releases (meaning locked processors, ones that can’t be overclocked, unlike K chips) won’t use the same number – as has previously been the case, where the ‘K’ is simply dropped (14900K, 14900). These will be named entirely differently as the Core Ultra 275, 255, and 240 (VideoCardz theorizes those would be Core Ultra 7 and Core Ultra 5 models).

There’s a further suggestion that we could get a Core Ultra 9 290K later on, which would be the equivalent of the ‘KS’ limited edition chips (14900KS).

The battle of the next-gen CPUs begins to take shape

If this is what happens, are these new names confusing? Well, they’re bound to sow some bewilderment among buyers initially, no doubt. For desktop CPUs, this represents a big change from the typical 14900K, 14700K and so on that we’ve been used to for a long time now.

However, these names do make sense based on the naming scheme for Meteor Lake (laptop) CPUs, and it’s fully expected that Intel will shift over to its Core Ultra branding across all chips, not just those for laptops.

At any rate, while the names may change, and confusion may be rife for some, the underlying core specs shouldn’t. With next-gen Arrow Lake desktop processors, the top die should still run with 8 performance cores and 16 efficiency cores, as is the case with Raptor Lake Refresh (and all recent generations).

As per another recent rumor, the other main die Intel will base Arrow Lake CPUs on has six performance cores plus eight efficiency cores – there’ll be a bunch of variants on both of these dies, as ever.

Arrow Lake seems to be in a bit of a strange place at the moment. Earlier leaks certainly suggested that these next-gen CPUs are going to be a massive performance leap for Intel – although that hype has died down somewhat (although it’s still far from extinguished).

What has surfaced more recently is doubts that Intel will get Arrow Lake out in a timely manner this year, with the prospect raised that these desktop CPUs may not hit the shelves until the very end of 2024.

The problem for Intel in that eventuality is that AMD’s Zen 5 processors could be out in Q3, if other rumors pan out, and that might mean these next-gen Ryzen CPUs – which are also expected to be a healthy step forward, performance-wise – are going to be given the space to really dominate for some time.

Especially if Arrow Lake volume is wonky to begin with, as other speculation has indicated, and Zen 5 (Ryzen 9000) is more affordable. With all that considered, AMD could be in a prime position to threaten Intel’s places in our ranking of the best CPUs. Add your own skepticism here, naturally, but that’s the way things look to be shaping up now.

The glimmer of positivity here is that with the naming scheme being spilled, perhaps this is an indication that Intel’s Arrow Lake CPUs aren’t as far off as some leakers seem to believe. Be even more cautious around that prospect, but still – we need all the good vibes around Arrow Lake that we can get, frankly. The keener the competition between these next-gen desktop processor ranges, the better things should be for the consumer, ultimately.

A new ZenHammer attack is targeting more AMD CPUs

No Comments on A new ZenHammer attack is targeting more AMD CPUs

[ad_1]

The infamous Rowhammer DRAM attack can now be pulled off on some AMD CPUs as well, academic researchers from ETH Zurich have proved.

As reported by BleepingComputer, the researchers dubbed the attack ZenHammer, after cracking the complex, non-linear DRAM addressing functions in AMD platforms.

For the uninitiated, the Rowhammer DRAM attack revolves around changing data in Dynamic Random Access-Memory (DRAM), by repeatedly “hammering”, or accessing, specific rows of memory cells. Memory cells keep information as electric charges. These charges determine the value of the bits, which can either be a 0, or a 1. As the density of the memory cells in today’s chips is fairly big, “hammering” can alter the state in adjacent rows, or “flip” the bit. By flipping specific bits, the attackers can pull cryptographic keys, or other sensitive data, BleepingComputer explained.

Purely theoretical?

This means that AMD has joined Intel and ARM CPUs who were already known to be vulnerable to hammering attacks.

The researchers tested their theory on different platforms. For AMD Zen 2, they were successful 70% of the time. For AMD Zen 3, 60%. For AMD Zen 4, however, they were only successful 10% of the time, suggesting that “the changes in DDR5 such as improved Rowhammer mitigations, on-die error correction code (ECC), and a higher refresh rate (32 ms) make it harder to trigger bit flips.”

While usually academic research is purely theoretical, the researchers said this attack could be pulled off in the real world, too. They simulated successful attacks targeting the system’s security, and manipulating page table entries for unauthorized memory access.

Those fearing ZenHammer, it’s important to stress that these types of attacks are quite difficult to pull off. What’s more, there are patches and mitigations. Earlier this week, AMD released a security advisory with mitigation options.
