Samsung Electronics to focus only on 6nm fab technology

By: Lana Jelic | More News: CPU, APU & Chipsets | Posted: Jun 29, 2017 6:33 pm

The battle of the top chips continues. Samsung Electronics is reportedly focusing on the next generation of 6nm chip fabrication technology. In order to do so, the Korean tech giant will stop further investments in the 7nm chip manufacturing technology.




Samsung is expected to introduce 8nm chips next year as an improved version of the 10nm technology, which has already been found in some of the best Android smartphones in 2017 so far. The Koreans will produce a limited number of 7nm line and focus its investment on the 6nm market.


Samsung should be installing two new ASML machines, vital for improving chip manufacturing efficiency, this year, and seven more in 2018. The manufacturing of Samsung's 6nm process and chips using it is expected to begin starting in 2019.

Intel X299 chipset: 'VRM disaster' says pro overclocker

By: Anthony Garreffa | More News: CPU, APU & Chipsets | Posted: Jun 29, 2017 9:12 am

UPDATE: The video points fingers at not just Intel and GIGABYTE, but also ASUS and MSI X299 motherboards. The video stated that the X299 Aorus Gaming 3, Prime X299-A, and MSI's X299 Gaming Pro Carbon VRMs throttled when all cores were overclocked to 4.6GHz on a test bench. It was also pointed out that with proper airflow, the VRMs do much better and shouldn't throttle. These motherboards are at the entry-level to mid-range side of each brands' X299 line up.


Intel's new X299 platform is now out, with various issues towed behind it, professional overclocker 'der8auer' says the platform is a complete "VRM disaster".



It's not just Intel that get the blame, but motherboard makers as well with der8auer saying that the blame is "50/50" on both Intel and motherboard companies. Intel's problems lie in the new X299 platform launching two months early, as it was meant to be released in August and came out in June. This forced motherboard makers into overdrive, with der8auer adding the companies had "almost zero time for developing proper products".


The total lack of consistency with the VRMs and their heat sinks is a major disappointment to der8auer in his chat, where he blames GIGABYTE's mediocre heat sinks on the VRMs that act as more of a "heat insulation" device instead of a cooler. This saw a GIGABYTE AORUS motherboard not capable of hitting 5GHz on a CPU that hits 5GHz on other motherboards, with the AORUS board hitting 4.6GHz with 'dangerously high VRM temperatures'.




A small fan over the VRM array was cooling it far more efficiently than the stock VRM cooler, and then der8auer tested a MSI motherboard that had similar issues with its VRM cooling and performance. It was also the lack of voltage input on most motherboards only being provided through a single 8-pin connector, which der8auer says isn't enough.


This is sure to set tongues wagging, as Intel just continues to stumble over itself trying to compete with AMD and its new Ryzen and upcoming Ryzen ThreadRipper CPUs, which at this rate are going to start making serious dents into Intel's image.

The new iMac Pro might feature server-grade co-processor

By: Anthony Garreffa | More News: CPU, APU & Chipsets | Posted: Jun 28, 2017 3:48 am

Apple is preparing their next-gen iMac Pro systems, which can be configured with Intel's new Purley-based CPUs rocking up to 18C/36T and ECC RAM for the best you can get in an AIO desktop PC.




These are the configurations we should expect for the new iMac Pro:


  • Intel 7980XE (18 cores/36 threads/42MB Cache/Turbo Boost TBD)
  • Intel 7900X (10 cores/20 threads/23MB Cache/Turbo Boost 3.0 Max 4.5GHz)
  • Intel 7820X (8 cores/16 threads/19MB Cache/Turbo Boost 3.0 Max 4.5GHz)


But, there's now news coming from Pikeralpha that one of the most interesting parts of Apple's new iMac Pro could be the fact that it uses an ARM co-processor. The use of an ARM co-processor would allow the iMac Pro to perfect regulate the power going through the machine, perfectly tweaking the CPU and GPU management to keep power draw down, and thus temperatures. This is incredible important for an all-in-one that rocks a 18C/36T processor, 128GB of ECC RAM, and a bunch of PCIe-based NVMe SSDs, and AMD's new Radeon Vega GPU architecture.

AMD EPYC: 64C/128T dual-CPU against Intel 56C/112T CPUs

By: Anthony Garreffa | More News: CPU, APU & Chipsets | Posted: Jun 27, 2017 4:59 am

AMD has been making some pretty serious waves with its Zen CPU architecture, but now that the enterprise/server-grade EPYC processors are here, Intel is in for a big fight - even with its spiffy new Xeon Platinum line of CPUs.




AMD's new EPYC 7601 comes in 32C/64T, but has been used in a dual-CPU server with a total of 64C/128T for some serious computational power - with SiSoft Sandra and Cinebench R15 2P benchmarks. We're seeing a competition between Intel's new 28C/56T processors in both single- and dual-CPU configurations, with a dual-CPU rig with Intel's new Xeon Platinum 8180 and a total of 56C/112T of power.


The benchmarks saw an average all-core CPU clock of 2.7GHz on all 64C/128T of AMD's dual EPYC 7601 system, while the dual Intel Xeon Platinum 8180 had 3.4GHz across all of its dual-CPU goodness at 56C/112T. In the Cinebench R15 performance, we're looking at AMD's EPYC 7601 scoring around 6879 points, while Intel's new Xeon Platinum 8180 pushes 8301.

Major flaw found in Intel CPUs and HT, needs BIOS fix

By: Anthony Garreffa | More News: CPU, APU & Chipsets | Posted: Jun 26, 2017 5:27 am

If Intel wasn't already in enough trouble with AMD's constant onslaught of products with Ryzen and now Ryzen ThreadRipper, the company is now going to have a huge storm surrounding it over a newly-discovered flaw in Intel's Skylake and Kaby Lake architectures with Hyper-Threading.




The HT-enabled processors with critical flaws were discovered on the Debian Linux user list, and sent out without a warning notification - but these issues extend to Windows, and other operating systems, too. The errors with HT-enabled Skylake/Kaby Lake CPUs can lead to various issues ranging from your entire system locking up, major data corruption or loss, or even more. As HotHardware points out: "the replication conditions are very specific and are unlikely to be encountered by most users in the wild". Still, it's not a good thing to see a company the size of Intel experiencing major issues like this, especially with AMD now competing in a big way in the CPU market again.


The problems surrounds Intel errata documentation, explained as:


Errata: SKZ7/SKW144/SKL150/SKX150/SKZ7/KBL095/KBW095

"Short Loops Which Use AH/BH/CH/DH Registers May Cause Unpredictable System Behavior."


Problem: "Under complex micro-architectural conditions, short loops of less than 64 instructions that use AH, BH, CH or DH registers as well as their corresponding wider register (e.g. RAX, EAX or AX for AH) may cause unpredictable system behavior. This can only happen when both logical processors on the same physical processor are active."


Implication: "Due to this erratum, the system may experience unpredictable system behavior."

Intel's next-gen 6C/12T: competes with AMD Ryzen 5 1600X

By: Anthony Garreffa | More News: CPU, APU & Chipsets | Posted: Jun 26, 2017 2:41 am

Intel has been reacting to AMD's new Ryzen CPUs with the tease and release of their new Core i9 processors, but the mainstream Coffee Lake CPUs that are set for a reported launch early next year are being teased more and more.




The latest on Intel's upcoming Coffee Lake-based Core i7 processors is that they will come out in 6C/12T flagship models, with similar to performance of AMD's Ryzen 5 1600X, which is also a 6C/12T processor. There's now a listing on the Geekbench database of a few new Intel processors, with a 6C/12T model with 1.5MB of L2 cache and 12MB of L3 cache. We should expect the 6C/12T processor to come with up to 3.5GHz base and 4.2GHz boost clocks, which is hefty for a 6C/12T mainstream CPU, especially from Intel.


With the Geekbench entry, the chip is clocked at 3.2GHz base, and has a single-core score of 4619 and multi-core score of 20,828. If we compare this against a retail AMD Ryzen 5 1600X processor, we have a single-score of 4574, and multi-core score of 20,769. Right on the money against the Ryzen 5 1600X.

Intel's next-gen Coffee Lake: 6C/12T @ 4.2GHz or more

By: Anthony Garreffa | More News: CPU, APU & Chipsets | Posted: Jun 22, 2017 2:07 am

Intel just launched its new Core i9 range of processors, but Coffee Lake news continues to roll out, as Coffee Lake is a refresh/optimized slice of Kaby Lake that supports more than 4 CPU cores.




A new engineering sample has turned up on the SiSoft Sandra benchmark database, showing that Intel will have 6C/12T CPUs at 3.5GHz, and over 4.2GHz with Turbo enabled. We should expect 256KB of L2 cache per core, and 9MB of shared L3 cache. There's also a variant of Coffee Lake that will include a larger 12MB of L3 cache, too.




We should expect the Coffee Lake-S series to come in 4C/8T with GT2 graphics, as well as 6C/12T with GT2 graphics. There will be Coffee Lake-S and Coffee Lake-H series processors, but we might see Intel change the socket from LGA 1151 to something else with Coffee Lake, but let's hope they don't - alright?

Intel's new Core i7-7740K overclocks to 5GHz easily

By: Anthony Garreffa | More News: CPU, APU & Chipsets | Posted: Jun 19, 2017 12:23 am

Intel is on the verge of releasing its new X299 platform, with its new Core i7-7740K processor that seems to be hitting 5GHz pretty easily, and at low voltages - so low temps, too.




VideoCardz has got the reviewers' guide on its hands, and based across 100 samples of the Core i7-7740K, it should hit 5GHz with just 1.205V of power. At its worst, the 7740K needs 1.341V to hit 5GHz. The guide says that the Core i7-7740K has a higher overclocking ceiling than the 7700K, with 5.1GHz achievable with 1.255-1.411V.
