Gigabyte Teases Z370 AORUS Gaming 7 Motherboard

Subject: Motherboards | September 28, 2017 - 01:31 AM |
Tagged: aorus, gigabyte, coffee lake, Z370, Z370 AORUS, RGB LED, gaming, overclocking

This week Gigabyte took the wraps off its lineup of Z370 motherboards that will support Intel’s 8th Generation Coffee Lake processors. The new lineup is comprised of five models that incorporate Gigabyte Ultra Durable technology, Dual BIOS, server grade digital power delivery, ESS Sabre DAC, a high-quality headphone amplifier, M.2 thermal guards, RGBW and Digital LED headers, and support for monitoring and control of fans and water pumps using RGB Fusion and Smart Fan 5 respectively. At the top of the lineup is the Gigabyte Z370 Aorus Gaming 7 which appears to have a lot to offer for enthusiasts planning a Coffee Lake build.

Gigabyte Z370 Aorus Gaming 7 Motherboard.png

The LGA 1151 socket is surrounded by an improved digital VRM setup that is rated at 60A per power phase. The board uses 10K Ultra Durable Black capacitors as well. The VRMs are cooled by large aluminum heatsinks as well as a small fan tucked away under the “thermal armor” above the rear I/O panel connectors. Using Gigabyte’s Smart Fan 5 technology, the built-in fan as well as CPU and case fans can be set to stop when the PC is idle and only spin up when needed.

Speaking of cooling, the board has eight fan/water pump Hybrid Fan headers (one is rated at 3A) and nine temperature sensors.

There are four DDR4 DIMM slots to the right of the processor socket that support up to 4400 MHz memory clockspeeds. Storage is handled by six SATA 6Gbps ports, two M.2 (PCI-E/SATA), and one smaller PCI-E M.2 slot with support for Intel’s Optane Memory technology. Expansion slots include three PCI-E x16 slots (x16/x8/x4) and three PCI-E x1 slots. Other internal headers include a USB 3.1 Gen 2 Type-C front panel, additional USB 3.1 Gen 1 ports, two RGBW LED headers, two Digital LED headers, two temperature sensor headers, and one Thunderbolt 3 Add-in card header. Power, reset, OC, and Clear CMOS buttons are also included on the board to make running it on a test bench and overclocking a bit easier.

For the RGB fans, there are several lighting zones on this board including on the VRMs, on the “Thermal Armor”, around the DIMM slots, around the PCI-E x16 slots, on the Z370 chipset heatsink, and a LED strip along the right side of the board that you can customize the look of with a 3D printer.

In addition to the Z370 chipset, Gigabyte is also using ASMedia silicon for additional USB 3.1 Gen 2 ports, a Realtek chip for a USB 3.1 Gen 1 hub, Intel GbE LAN and Rivet Networks Killer E2500 NIC for Gigabit Ethernet, and Realtek ALC1220 audio codec for audio.

On the audio front, Gigabyte is spicing things up a bit by pairing that Realtek ALC1220 audio codec with an ESS9018Q2C DAC, Nichicon and WIMA audio capacitors, independent analog power(LME49720), a smart headphone amp (auto-detects impedance), gold plated audio jacks, and support for USB DAC-UP 2 technology (adjustable voltage to compensate for voltage drop).

Around back the Aorus Gaming 7 features:

  • 1 x PS/2
  • 1 x DisplayPort
  • 1 x HDMI
  • 5 x USB 3.1 Gen 1
  • 1 x USB 3.1 Gen 2 Type-C
  • 1 x USB 3.1 Gen 2 Type A
  • 2 x RJ45 (Gigabit Ethernet)
  • 1 x S/PDIF
  • 5 x 3.5mm audio out.

It appears that Gigabyte has packed a lot of hardware into its flagship Z370 motherboard, and with the actively cooled VRMs it should be a decent overclocker even when using water cooling for the CPU (though noise from the small fan might be an issue). Unfortunately, Gigabyte has not yet released pricing information. On the bright side, there are several models in the Aorus Z370 lineup for those that do not want the Killer networking, third PCI-E x16 slot, as many LEDs, or ESS Sabre audio where there is room to save some money to put towards a graphics card or monitor. I'll leave it up to Sebastian and Morry to determine if the audio is audiophile and CMOS placement is good enough respectively.

What are your thoughts on the Aorus Z370 lineup? Is it enough to entice you to upgrade to Coffee Lake?

Tagged: seasonic, PRIME PSU, 80 Plus Platinum, 650W

Lee has reviewed several of Seasonic's PRIME PSUs, focusing on the higher wattage models and awarding high honours for the models tested.  Not everyone needs a kilowatt class PSU however, which makes [H]ard|OCP's review of the new 650W member of the PRIME family interesting.  Externally the PSU is indistinguishable from the higher wattage models, it is only in the interior that you can see the differences.  Those differences do not have an effect on the quality of power provided by this PSU, as [H] describes it as the best 650W model they have seen to date.  The price is a little higher than other 650W PSUs, making the 850W model a better deal for some.  Drop by to get the full story.

150454301442q7i5obio_3_8_l.jpg

"This time we review a small Seasonic rated at 650 watts, but this one is part of its flagship Prime series with Platinum rated efficiency. That means, less heat, less noise, and a lower cost of operation over time. So, is the PRIME 650 Platinum PSU worthy of Seasonic's flagship status? We will surely find out."

Tagged: moores law, nvidia, jen-hsun huang

You've heard this one before, though not from Jen-Hsun Huang of NVIDIA who has a vested interest in seeing Moore's Law finally be relegated to computing history.  NVIDIA is pushing GPUs as a better alternative to CPUs for a variety of heavy computational lifting.  Volta has been adopted by many large companies and he also just announced TensorRT3 a programmable inference accelerator with applications in self-driving cars, robotics and numerous other tasks previously best done with a CPU.  DigiTimes quotes Jen-Hsun as saying "while number of CPU transistors has grown at an annual pace of 50%, the CPU performance has advanced by only 10%", more or less accurate in broad strokes but certainly not a death rattle yet.

Intel has a different opinion of course, reporting Moore's Law to be perfectly healthy just last Tuesday.

The retro Ataribox comes with new AMD hardware

Subject: General Tech | September 26, 2017 - 12:45 PM |
Tagged: atari, ataribox, amd, Indiegogo

Atari have released a tiny trickle of new information about their somewhat mysterious Ataribox; it will run some flavour of Linux on AMD hardware and cost somewhere between $250 to $300.  They describe their upcoming product as equivalent to a mid-range PC, not quite up to running AAA games but able to handle Minecraft or Terraria in addition to classic Atari games.  This will make it somewhat more expensive than an NVIDIA Shield and more on par with a current generation gaming console; somewhat apt as they too rely on AMD hardware.

Atari will be launching an Indiegogo campaign this fall to fund the Ataribox, with an expected release 12 months after that launch date.  While the idea is intriguing, for who doesn't want to play old Atari games on a nice looking machine; one wonders if Atari can honestly refer to themselves as struggling entrepreneurs in need of assistance in launching a product.  Drop by The Inquirer for more.

"The Ataribox will be based on PC tech, and as such won't be tied to any one ecosystem. Now, usually this would send us screaming for the hills, but we know this one is going to get funded, so we're not sweating about sharing some more info."

What's New, Plexycat? Plex News Adds Customized News Clips to Your Media Library

Subject: General Tech | September 26, 2017 - 09:00 AM |
Tagged: plex server, plex pass, plex news, plex, news

Plex has always been an excellent way to organize the movies, TV shows, and other media that you already have, but one area in which it has traditionally lacked is outside content. The Plex team has taken steps to address this in recent years, first with the introduction of DVR support in late 2016 and followed by the ability to watch live TV this past June. Now Plex has set its sights on another area of outside content: news.

plex-news-my-newscast.jpg

Plex today announced Plex News, a new service that aggregates recent video clips from over 190 global and local news publishers and integrates them "seamlessly and beautifully" into your media library. The initiative is based upon Watchup, a personalized news aggregation service that Plex acquired last January. Users can choose the topics and sources of news they prefer, and Plex will create custom video feeds containing each day's news. "AI and machine learning" will then learn the type of content each users prefers and automatically adapt the user's news feed as new videos and content sources are added.

Plex News is especially exciting to us because it follows a progression we started with Live TV and DVR where we’re bringing you great media from outside your library in a way which integrates seamlessly and beautifully. This makes it easier than ever to start using Plex if you’re new, and gives you another universe of content to explore outside of your own media, without ever leaving Plex.

In addition to clips from expected sources like CNN and the CNET, Plex claims that it has reached a deal to provide users with local news in more than 80 percent of U.S. markets as well, which positions Plex as a unique source for both enjoying your on-demand content library and keeping up with important events in the "real world."

plex-news-ios.jpg

Plex News is launching as a free ad-supported service and will roll out to all users over the next two days, starting first with Plex Pass subscribers. It is available at launch for Android TV (including NVIDIA SHIELD), Apple TV, Roku, Android Mobile, and iOS, with support for other platforms to follow.

Imagination Technologies is known to develop interesting, somewhat offbeat hardware, such as GPUs with built-in ray tracers. In this case, the company is jumping into the neural network market with a Power VR-branded accelerator. The PowerVR Series2NX Neural Network Accelerator works on massively parallel, but low-precision tasks. AnandTech says that the chip can even work in multiple bit-depths on different layers in a single network, from 16-bit, down to 12-, 10-, 8-, 7-, 6-, 5-, and 4-bit.

Imagination seems to say that this is variable “to maintain accuracy”. I’m guessing it doesn’t give an actual speed-up to tweak your network in that way, but I honestly don’t know.

As for Imagination Technologies, they intend to have this in mobile devices for, as they suggest, photography and predictive text. They also state the usual suspects: VR/AR, automotive, surveillance, and so forth. They are suggesting that this GPU technology will target Tensorflow Lite.

The PowerVR 2NX Neural Network Accelerator is available for licensing.

Intel Core i9-7980XE Pushed to 6.1 GHz On All Cores Using Liquid Nitrogen

Subject: Processors | September 25, 2017 - 09:36 PM |
Tagged: skylake-x, overclocking, Intel Skylake-X, Intel, Cinebench, 7980xe, 3dmark, 14nm

Renowned overclocker der8auer got his hands on the new 18-core Intel Core i9-7980XE and managed to break a few records with more than a bit of LN2 and thermal paste. Following a delid, der8auer slathered the bare die and surrounding PCB with a polymer-based (Kryonaut) TIM and reattached the HIS to prepare for the extreme overclock. He even attempted to mill out the middle of the IHS to achieve a balance between direct die cooling and using the IHS to prevent bending the PCB and spread out the pressure from the LN2 cooler block, but ran into inconsistent results between runs and opted not to proceed with that method.

Core i9-7980xe LN2 overclock.png

Using an Asus Rampage VI Apex X299 motherboard and the Core i9-7980XE at an Asus ROG event in Taiwan der8auer used liquid nitrogen to push all eighteen cores (plus Hyper-Threading) to 6.1 GHz for a CPU-Z validation. To get those clockspeeds he needed to crank up the voltage to 1.55V (1.8V VCCIN) which is a lot for the 14nm Skylake X processor. Der8auer noted that overclocking was temperature limited beyond this point as at 6.1 GHz he was seeing positive temperatures on the CPU cores despite the surface of the LN2 block being as low as -100 °C! Perhaps even more incredible is the power draw of the processor as it runs at these clockspeeds with the system drawing as much as 1,000 watts (~83 amps) on the +12V rail with the CPU being responsible for almost all of that number! That is a lot of power running through the motherboard VRMs and the on-processor FIVR!

For comparison, at 5.5 GHz he measured 70 amps on the +12V rail (840W) with the chip using 1.45V vcore under load.

7980xe CPU-Z overclock 6GHz.png

For Cinebench R15, the extreme overclocker opted for a tamer 5.7 GHz where the i9-7980XE achieved a multithreaded score of 5,635 points. He compared that to his AMD Threadripper overclock of 5.4 GHz where he achieved a Cinebench score of 4,514 (granted the Intel part was using four more threads and clocked higher).

To push things (especially his power supply heh) further, the overclocker added a LN2 cooled NVIDIA Titan Xp to the mix and managed to overclock the graphics card to 2455 MHz at 1.4V. With the 3840 Pascal cores at 2.455 GHz he managed to break three single card world records by scoring 45,705 in 3DMark 11, 35,782 in 3DMark Fire Strike, and 120,425 in 3DMark Vantage!

Der8auer also made a couple interesting statements regarding overclocking at these levels including the issues of cold bugs not allowing the CPU and/or GPU to boot up if the cooler plate is too cold. On the other side of things, once the chip is running the power consumption can jump drastically with more voltage and higher clocks such that even LN2 can’t maintain sub-zero core temperatures! The massive temperature delta can also create condensation issues that need to be dealt with. He mentions that while for 24/7 overclocking liquid metal TIMs are popular choices, when extreme overclocking the alloy actually works against them because the sub-zero temperatures reduce the effectiveness and thermal conductivity of the interface material which is why polymer-based TIMs are used when cooling with liquid nitrogen, liquid helium, or TECs. Also, while most people apply a thin layer of thermal paste to the direct die or HIS, when extreme overclocking he “drowns” the processor die and PCB in the TIM to get as much contact as possible with the cooler as every bit of heat transfer helps even the small amount he can transfer through the PCB. Further, FIVR has advantages such as per-core voltage fine tuning, but it also can hold back further overclocking from cold bugs that will see the processor shut down past -100 to -110 °C temperature limiting overclocks whereas with an external VRM setup they could possibly push the processor further.

ASUS' take on single board computers is the new Tinker Board, powered by a 1.8 GHz Cortex-A17 based Rockchip RK3288 and a 600MHz Mali-T760 GPU which share 2 GB of LPDDR3.  Storage is handled by a microSD slot, or the four USB 2.0 ports and the Tinker offers Gigabit wired connectivity as well as optional WiFi.  You have a choice of operating systems, either Marshmallow flavoured Android or the Debian based Tinker OS, depending on which you prefer. 

The Tech Report tested out the Tinker Board and found the hardware to outpace competitors such as Raspberry Pi, however the lack of software and documentation hamstrung the Tinker Board badly enough that they do not recommend this board.  This may change in time but currently ASUS needs to do some work before the Tinker Board becomes an actual competitor in this crowded market.

"Asus' Tinker Board single-board computer wants to challenge the Raspberry Pi 3's popularity with a more powerful SoC and better networking, among other improvements. We put it to the test to see whether it's a worthy alternative to the status quo."

Double the price; not so much performance though ... Skylake-X versus ThreadRipper

Subject: Processors | September 25, 2017 - 03:19 PM |
Tagged: skylake-x, Skylake, Intel, Core i9, 7980xe, 7960x

You cannot really talk about the new Skylake-X parts from Intel without bringing up AMD's Threadripper as that is the i9-7980XE and i9-7960X's direct competition.   From a financial standpoint, AMD is the winner, with a price tag either $700 or $1000 less than Intel's new flagship processors.  As Ryan pointed out in his review, for those whom expense is not a consideration it makes sense to chose Intel's new parts as they are slightly faster and the Xtreme Edition does offer two more cores.  For those who look at performance per dollar the obvious processor of choice is ThreadRipper; for as Ars sums up in their review AMD offers more PCIe lanes, better heat management and performance that is extremely close to Intel's best.

"Ultimately, the i9-7960X raises the same question as the i9-7900X: Are you willing to pay for the best performing silicon on the market? Or is Threadripper, which offers most of the performance at a fraction of the price, good enough?"

Skimmer Scanner, a start to protecting yourself at the pump

Subject: General Tech | September 25, 2017 - 01:12 PM |
Tagged: skimmer scanner, security, bluetooth

If you haven't seen the lengths which scammers will go to when modifying ATMs to steal your bank info you should really take a look at these pictures and get in the habit of yanking on the ATM's fascia and keyboard before using them.  Unfortunately as Hack a Day posted about last week, the bank is not the only place you have to be cautious, paying at the pump can also expose your details.  In this case it is not a fake front which you need to worry about, instead a small PIC microcontroller is attached to the serial connection between card reader and pump computer, so it can read the unencrypted PIN and data and then store the result in an EEPROM device for later collection.  The device often has Bluetooth connectivity so that the scammers don't need to drive right up to the pump frequently.

There is an app you can download that might be able to help stop this, an app on Google Play will detect Bluetooth devices utilizing the standard codes the skimmers use and alert you.  You can then tweet out the location of the compromised pump to alert others, and hopefully letting the station owner and authorities know as well.  The app could be improved with automatic reporting and other tools, so check it out and see if you can help improve it as well as keeping your PIN and account safe when fuelling up.

"It would be nice to think that this work might draw attention to the shocking lack of security in gas pumps that facilitates the skimmers, disrupt the finances of a few villains, and even result in some of them getting a free ride in a police car. We can hope, anyway."

Noctua Focused on Ryzen with NH-L9a-AM4 and NH-L12S Low-Profile Coolers

Subject: Cases and Cooling | September 25, 2017 - 10:43 AM |

AMD's popularity with Ryzen CPUs (and upcoming APUs) has made waves across the industry, and Noctua have jumped in with a pair of low-profile offerings that update previous designs for cramped case interiors.

First up is the new version of the NH-L9a:

noctua_nh_l9a_am4_1.jpg

"The new NH-L9a-AM4 is an AM4-specific revision of Noctua’s award-winning NH-L9a low-profile CPU cooler. At a height of only 37mm, the NH-L9a is ideal for extremely slim cases and, due to its small footprint, it provides 100% RAM and PCIe compatibility as well as easy access to near-socket connectors, even on tightly packed mini-ITX motherboards."

Next is the new NH-L12S:

noctua_nh_l12s_1.jpg

"The new S-version of the renowned NH-L12 not only adds AM4 support but also gives more flexibility and improved performance in low-profile mode. Thanks to the new NF-A12x15 PWM slim 120mm fan, the NH-L12S provides even better cooling than the previous model with its 92mm fan. At the same time, the NH-L12S is highly versatile: with the fan installed on top of the fins, the cooler is compatible with RAM modules of up to 45mm in height. With the fan installed underneath the fins, the total height of the cooler is only 70mm, making it suitable for use in many compact cases."

Noctua says that these new coolers now shipping "and will be available shortly", with an MSRP of $39.90 for the NH-L9a-AM4 and $49 for the NH-L12S.

Intel Announces 8th Gen Core Architecture, Coffee Lake

Subject: Processors, Chipsets | September 24, 2017 - 11:03 PM |
Tagged: Z370, Intel, coffee lake

The official press deck for Coffee Lake-S was leaked to the public, so Intel gave us the go-ahead to discuss the product line-up in detail (minus benchmarks). While the chips are still manufactured on the 14nm process that Kaby Lake, Skylake, and Broadwell were produced on, there’s more on them. The line-up is as follows: Core i3 gets quad-core without HyperThreading and no turbo boosting, Core i5 gets six-core without HyperThreading but with Turbo boosting, and Core i7 gets six-core with HyperThreading and Turbo boosting.

While the slide deck claims that the CPU still has 16 PCIe 3.0 lanes, the whole platform supports up to 40. They specifically state “up to” over and over again, so I’m not sure whether that means “for Z370 boards” or if there will be some variation between individual boards. Keep in mind that only 16 lane of this are from the processor itself, the rest are simply a part of the chipset. This unchanged from Z270.

Moving on, Intel has been branding this as “Intel’s Best Gaming Desktop Processor” all throughout their presentation. The reasoning is probably two-fold. First, this is the category of processors that high-end, mainstream, but still enthusiast PC gamers target. Second, gaming, especially at super-high frame rates, is an area that AMD has been struggling with on their Ryzen platform.

Speaking of performance, the clock rate choice is quite interesting compared to Kaby Lake. In all cases, the base clock had a little dip from the previous generation, but the Turbo clock, if one exists, has a little bump. For instance, going from the Core i7-7700k to the Core i7-8700k, your base clock drops from 4.2 GHz to just 3.7 GHz, but the turbo jumps up from 4.5 GHz to 4.7 GHz. You also have a little more TDP to work with (95W vs 91W) with the 8700k. I’m not sure what this increase variance between low and high clock rates will mean, but it’s interesting to see Intel making some sort of trade-off on the back end.

(Editor's note: the base clock is only going to be a concern when running all cores for a long period of time. I fully expect performance to be higher for CFL-S parts than KBL-S parts in all workloads.)

The last thing that I’ll mention is that, of the two i3s, the two i5s, and the two i7s, one is locked (and lower TDP) and one is unlocked. In other words, Intel has an unlocked solution in all three classifications, even the i3. Even though it doesn’t have a turbo clock setting, you can still overclock it by hand if you desire.

Prices range from $117 to $359 USD, as seen in the slide, above. They launch on October 5th.
