Intel's Skylake-X to use an Integrated Voltage Regulator

By: Steven Bassiri | More News: CPU, APU & Chipsets | Posted: Jun 14, 2017 3:33 am

Remember the fully integrated voltage regulator ( FIVR) introduced with Haswell CPUs? Turns out that news of Intel axing the technology was not completely true. Intel's previous FIVR was implemented to reduce motherboard voltage regulator (VR, VRM, or MBVR) complexity, as it fed the CPU a single voltage and the CPU then internally branched off, reduced, and controlled the other voltages needed for other CPU domains (graphics, system agent, cache, IO, etc.).




Traditionally, CPU voltage regulators are fed 12v from your main system power supply, and then they reduce it down to voltages below 2v for the CPU and its different domains. However, as CPUs became more complex they required multiple separate VRs, each with their own controllers (PWM Controller). Adding more external VRs not only increases motherboard costs because of the need for each VR to be individually controlled, but also more importantly, it takes up motherboard real estate which is scarce on a motherboard with eight memory DIMMs surrounding the CPU. Over the past week, Intel quietly made public volume 1 of the Skylake-X datasheet, and you can find it here: Intel Skylake-X Datasheet Volume 1 of 2.


In table 1-1 on page 14 we find that "IVR" will be referenced in the datasheet, and it stands for "Integrated Voltage Regulation (IVR): The processor supports several integrated voltage regulators." Later in the datasheet we find reference to the fact that the IVR is related to the previous FIVR through a signal name called "FIVR_Fault", which "Indicates an internal error has occurred with the integrated voltage regulator. The FIVR_FAULT signal can be sampled any time after 1.5 ms..." We then learn further down about the VCCIN signal, "1.8 V - 1.55 V input to the Integrated Voltage Regulator (IVR) for the processor cores, lowest level caches (LLC), ring interface, PLL, IO, and home agent. It is provided by a VR 13.0 compliant motherboard voltage regulator (MBVR) for each CPU socket.

AMD Ryzen ThreadRipper 1950X: 16C/32T @ 3.4GHz base

By: Anthony Garreffa | More News: CPU, APU & Chipsets | Posted: Jun 14, 2017 1:26 am

AMD really has the high-end desktop market in a twist with their upcoming Ryzen ThreadRipper CPUs, with a new tease of the Ryzen ThreadRipper 1950X processor, a 16C/32T part with a purported 3.4GHz base clock.




The latest news is comign from a purported engineering sample on the ThreadRipper 1950X processor, which packs a base CPU clock of 3.4GHz and XFR boost clock of up to 3.7/3.8GHz. We should expect a huge 32MB of L3 cache, 8MB of L2 cache, bringing us to a total of 40MB of cache. In some benchmarks, it has been compared to Intel's higher-end Xeon E5-2697A V4 processor that features 16C/32T @ 2.6GHz base and 3.6GHz boost.




The multi-core score of the Xeon processor is 30,450 while the ThreadRipper 1950X hits 24,539... but I'm sure there are plenty of optimizations that AMD will be making just like the normal Ryzen CPUs, and then the motherboard makers will surely optimizations for ThreadRipper and its multi-core performance.

Intel Core i9-7900X: 10C/20T @ 5GHz on AIO liquid cooler

By: Anthony Garreffa | More News: CPU, APU & Chipsets | Posted: Jun 13, 2017 1:45 am

Intel's new Core i9 range is getting flashed around, with the upcoming 10C/20T part hitting 5GHz with an AIO liquid cooler. Intel's upcoming Core i9-7900X has reached 5GHz with the AIO liquid cooler, and even 4.5GHz on air, all on 1.15V - and with all CPU cores enabled.



The new Core i9-7900X will arrive with 10C/20T of CPU power, 13.75MB L3 cache, and 3.3/4.3GHz for base/boost, respectively. But Intel's new Turbo Boost 3.0 technology will overclock the 10C/20T chip to 4.5GHz, which is a huge upgrade over the current high core count CPUs like the Core i7-6950X. Intel's upcoming Core i9-7900X will have a TDP of 140W, and its X299 chipset will feature 44 PCIe 3.0 lanes.



Intel will be pricing the new 10C/20T Core i9-7900X at $999, and considering the Core i7-6950X debuted at $1500 and is still $1500 on Amazon right now - all with the same 10C/20T, but at much lower clocks (3.0/3.5GHz for base/boost), it's a steal. AMD will be competing big time with their upcoming Ryzen ThreadRipper CPUs offering up to 16C/32T, but their spiffy new X399 chipset rocks 64 PCIe 3.0 lanes, beating Intel out by a fair chunk.

Intel's beasty 18C/36T processor launching in October

By: Anthony Garreffa | More News: CPU, APU & Chipsets | Posted: Jun 13, 2017 12:52 am

Intel is reportedly launching its new Core i9 range of processors next month, starting with the Core i9-7920X (12C/24T) but the 14C/28T, 16C/32T, and 18C/36T processors will be launching in October.




The first phase of Intel's new Core launch will see the 4/6/8/10-core models launch, while the second phase will see the 12C/24T chip launch, and then finally the mudslide of 14/16/18-core parts. Intel will reportedly begin accepting pre-orders of the new 4/6/8/10-core Kaby Lake-X and Skylake-X processors on June 19, shipping to consumers on June 26. All of these processors will work on the new X299 chipset.


Intel's upcoming 12C/24T processor in the Core i9-7920X will launch in August for a hefty $1199, while the super high-end Core i9-7980XE with 18C/36T of power will launch in October.

Intel's next-gen 10nm 'Cannon Lake' CPUs announced

By: Anthony Garreffa | More News: CPU, APU & Chipsets | Posted: Jun 12, 2017 2:33 am

Intel has just made its upcoming Cannon Lake CPU architecture official, with its 9th-gen Core processor on track and made on the 10nm process.




Intel also took the time to announce that its second micro-architecture built on 10nm is taped out, with details on Ice Lake to follow. Intel is reacting in a scared fashion as I said months and months ago now, throwing out its 18C/36T processor at Computex 2017 without any details, a gimped X299 chipset compared to the ThreadRipper ready X399 chipset from AMD which has 64 PCIe 3.0 lanes compared to just 44 PCIe 3.0 lanes on X299.


The new Cannon Lake CPUs will be a die shrink of the Coffee Lake chips, so don't expect huge things from it, apart from lowered TDP and possibly higher clocks. Ice Lake will be the bigger one, something like the upgrade from Broadwell to Skylake, and is expected in 2H 2018.

Intel Xeon Platinum 8176 dual CPU: 56C/112T benchmarks

By: Anthony Garreffa | More News: CPU, APU & Chipsets | Posted: Jun 11, 2017 11:39 pm

While the consumer CPU world is tangled up in AMD's upcoming ThreadRipper that comes with up to 16C/32T, Intel is wrapping up their next-gen Xeon Platinum line with the flagship Xeon Platinum 8176 processor that rocks 28C/56T of processing power.




Better yet, Intel's upcoming Xeon Platinum 8176 can be used in dual CPU socket configurations, and with each CPU featuring 28C/56T, you'd be looking at 56C/112T of CPU performance. Intel's new Xeon Platinum 8176 comes with a stock 2.1GHz CPU clock, while a single core can ramp up to 3.8GHz, the all cores enabled Turbo clock hits 2.8GHz. It's a beast.


But what good are the specs of this 28C/56T processor without benchmarks? Intel's new Xeon Platinum 8176 scored 6525 points in Cinebench R15 (which supports more than 16 threads), blasting past the 44C/88T dual-CPU socket Intel Xeon E5-2696 v4 processor... amazing stuff.

Intel CPU with AMD GPU spotted, GPU licensing confirmed?

By: Anthony Garreffa | More News: CPU, APU & Chipsets | Posted: Jun 9, 2017 12:37 pm

It was rumored quite a while ago now, but it's back: the news of a future Intel processor with AMD graphics has been spotted.




The chip was on Sisoft as "Intel(R) HD Graphics Gen9; 694C:C0 (1720SP 47C 1GHz, 528kB L2, 10.4GB 800MHz)" but if you'll note the hardware ID "644C:C0" which is reportedly the hardware ID code for AMD. There is absolutely nothing known about this processor that is concrete, so treat this as a hot rumor - but the CPU is a 2T processor, presumably 2C/2T APU with AMD Radeon graphics. The rumors of the Intel/AMD GPU licensing deal could be true if this CPU is the real deal.

AMD Ryzen ThreadRipper: 16C/32T @ 3.7GHz sample teased

By: Anthony Garreffa | More News: CPU, APU & Chipsets | Posted: Jun 9, 2017 12:15 pm

The first engineering sample of AMD's upcoming Ryzen ThreadRipper is reportedly here, with the Ryzen ThreadRipper 1920 processor rocking 12C/24T of CPU performance.




AMD's first Ryzen ThreadRipper 1920 chip will have its 12C/24T of power at 3.2GHz base clock, but we don't know what the boost clock will be under XKR. The higher-end 16C/32T processor without a name just yet, rumored as the ThreadRipper 1998X will have 3.4GHz base CPU clock, while under XFR it will hit 3.7GHz and hopefully, beyond.


There's also another 16C/32T chip at 3.1GHz base and 3.6GHz boost, another engineering sample. There's also the Ryzen 3 1200 processor, with its 4C/4T power at 3.1/3.6GHz for base/boost respectively.

Core i7-7740K overclocked to 7.5GHz with liquid helium

By: Anthony Garreffa | More News: CPU, APU & Chipsets | Posted: Jun 8, 2017 12:47 am

Computex 2017 - GIGABYTE hosted their X299 OC gathering at Computex 2017 last week, bringing in a bunch of the world's leading overclocking enthusiasts and hit a new world record with the Intel Core i7-7740K: hitting 7.5GHz.



Legendary overclocker HiCookie reached 7.5GHz using liquid helium at -250C, pushing the Core i7-7740K to 7500MHz on a multiplier of 75, and a bus speed of 100MHz on the GIGABYTE X299-SOC Champion motherboard. They used a 16GB kit of Corsair Vengeance LPX DDR4-4333 RAM, and a Corsair AX1500i PSU.


The team used the Core i7-7740K @ 7.5GHz teamed with an AORUS GeForce GTX 1080 Ti Xtreme Edition 11G graphics card and G.Skill Trident-Z 3600C17 RAM to smash the world records in 3DMark 03, 3DMark 06, and Aquamark benchmarks. The GTX 1080 Ti was then thrown into an SLI mix, hitting the global first place in 3DMark 06 with 71,176.

Samsung's mid-range Exynos chips leak

By: Lana Jelic | More News: CPU, APU & Chipsets | Posted: Jun 6, 2017 9:21 pm

Two new Exynos SoCs have leaked online suggesting that Samsung could be introducing new SoCs for mid-range devices.


The first processor is the Exynos 9610 which is a step below the company's current leading SoC, the Exynos 8895. The Exynos 9610 is expected to use the 14nm process similar to the one used by the Exynos 8890 inside of the Galaxy S7.




The 9610 doesn't use a combination of Samsung's Mongoose cores with A53 cores, but rather off-the-shelf A73 cores instead. The interesting development is the inclusion of ARM's new G72 GPU which was announced at Computex and should be a pretty sizable upgrade over the G71 in the previous generation. It also has Cat. 13 LTE which isn't quite as fast as what's in the Exynos 8895.
