Mark Papermaster on AMD's tiny things

Subject: General Tech | July 24, 2017 - 12:49 PM |
Tagged: amd, 7nm

Over at The Inquirer you can read a condensed version of AMD's Mark Papermaster discussion about the challenges of moving to a 7nm process node.  The size of AMD's design team have prompted them to take a modular approach to design so that circuits can be reused across CPU, GPU and semi-custom designs.  That allows the the same teams to work on multiple projects and for design successes to improve products across multiple lines, a must for a small team with such diverse products.

He also talks about "2.5-D chip stacks", using silicon interposers to connect processors and memory stacks side-by-side as a way to work on reducing to the 7nm node while waiting for foundries like GLOFO to retool to EUV lithography. He ends with a familiar request; that developers switch their focus to taking advantage of high core counts and parallel threads and away from single cores running at high frequencies.

"Speaking to the EE Times, Papermaster said that, while AMD planned to run its second and third generation Zen architecture x86 microprocessors on 7nm, it would likely be a 'long node', like the 28nm process, "and when you have a long node it lets the design team focus on micro-architecture and systems solutions", rather than simply redesigning standard ‘blocks'."

AMD Teases Ryzen Threadripper Packaging, Lisa Su for Scale

Subject: Processors | July 24, 2017 - 12:19 PM |
Tagged: amd, ryzen, Threadripper, lisa su

The AMD social teams have been had at work this morning, teasing out images of the packaging for its upcoming Ryzen Threadripper retail processor.

The first image shows a window into the packaging with the Threadripper processor clearly visible behind it. The Ryzen logo dominates the plastic cover though there is a scene of "space" or maybe the Eye of Sauron in the background. The black construction looks to be foam that opens by splitting in half, across the Ryzen logo.

The second image shows the relative size of it all, with AMD CEO Lisa Su for scale. It looks kind of like an old-time portable TV and the depth of the packaging is definitely more substantial from the first image. 

We are getting closer and closer to the official unveiling of this product family and AMD is doing a fantastic job of pulling the community along for the ride.

CRYORIG's A40; two heads are better than one?

Subject: Cases and Cooling | July 21, 2017 - 03:49 PM |
Tagged: CRYORIG, CRYORIG A40, AIO, water cooler

The CRYORIG A40 is not a new cooler but its unique design is worth revisiting for those who have forgotten about its existence.  Instead of having a single area in which to dump heat, the pump assembly mounted to the CPU also has its own fan.  That fan did not not noticeably decrease the CPU temperatures when TechPowerUp tested it, however for SFF systems and other builds with components which could benefit from airflow inside the case that fan is more than just a gimmick.  Check out the full review here.

"The A40 by CRYORIG is the company's entry level offering in their all-in-one hybrid liquid CPU cooler lineup. It lacks the size of the A80 and the radiator thickness of the A40 Ultimate. However, unlike the others, it offers a more affordable price point with all the same features."

Devil's Ivy, a voyeurs dream come true

Tagged: iot, Devil's Ivy, cameras, security, gSOAP

gSOAP is a open-source code library which allows hardware to be configured and controlled via web connections and is used by hundreds of companies including Axis, Microsoft, IBM, Adobe and Xerox.  It has a vulnerability which allows an attacker to trigger a stack overflow by sending a specific POST command over port 80 to a device, which in the case of cameras allows you to watch the live feed.  The vulnerability was patched in an update to gSOAP so future products will not have this issue, however any camera built on that library which currently in use is vulnerable.  The manufacturers would have to create an update to their own software and push it out to all the cameras currently in use to resolve this issue, and if there is one thing we know for sure about IoT products, it is that these patches do not tend to be created, let alone pushed out.

A new BioStar has Ryzen, the Racing X370GT7

Subject: Motherboards | July 19, 2017 - 04:23 PM |
Tagged: x370, ryzen, Racing X370GT7, biostar, amd, AM4

BioStar have greeted the release of AMD's Ryzen with enthusiasm, releasing numerous AM4 boards, some of which are garnering better reviews than the main brands.  [H]ard|OCP tested out their Racing X370GT7, an ATX model with a ~$160 price tag.  The silkscreen on the board is rather unique and the layout is extremely clean.  You get a lot of nice high end features such as a heatsink for the M.2 slot located just below the CPU socket, Realtec ALC1220 8 channel audio and even an LN2 switch for extreme overclockers.  As with many other X370 boards there were some quirks with memory compatibility as well as some questionable UEFI choices specific to this board.  It will offer a solid base for someone building a Ryzen platform and it will likely improve as the AMD Generic Encapsulated Software Architecture for AM4's matures.

"BIOSTAR isn’t exactly a juggernaut of a manufacturer here in the U.S. Despite stiff competition, the big boys are blowing it bad enough at the X370 Ryzen motherboard game that BIOSTAR’s X370GT7 just might be one of the best AM4 motherboard options around. While we think it might actually be good, it still doesn’t make for a smooth ride."

It's dangerous to go alone; gaming on a Lenovo X1 Carbon ultrabook

Subject: General Tech | July 19, 2017 - 03:01 PM |
Tagged: gaming, ultrabook, Lenovo, ThinkPad X1 Carbon

Techspot recently investigated the ability of current generation ultrabooks to game, without external assistance.  They tested using a Lenovo X1 Carbon, similar to what Ken utilized when he benchmarked the AKiTiO Node external GPU.  Techspot's model had a Core i5-7200U as opposed to the 7300U both chips have the same HD 620 iGPU, but only Ken's had help. 

Techspot focused on the performance the ultrabook could provide in 34 different games, from current and past AAA games as well as eSports and even 2D indie games.  Take a look through their results to see just how far we have come since the original generations of Intel iGPUs which simply could not game at all.  The results show that there is indeed a market for Thunderbolt based external GPUs.

You've got to go deep before you can be extreme, TSMC is moving to 7nm

Subject: General Tech | July 19, 2017 - 12:41 PM |
Tagged: TSMC, 7nm, duv, N7, euv

TSMC is preparing for the move to a 7nm process by expanding suppliers and tooling up for Deep UV equipment.  Unlike Samsung, who will be using Extreme UV tools for their initial launch of 7nm product in 2018 TSMC have chosen to delay the move to EUV until the technology matures.  They will instead use DUV for its launch of their 7nm products, dubbed 7N, in 2018.  The difference between the two types of UV is the wavelength, DUV can be produced at 248 and 193 nm while EUV is an impressive 13.5nm, which is why the industry (and ourselves) depend on this process maturing and being adopted by manufacturers.  The EUV equipment that is being tested is still relatively new but should produce a better chip in theory, though perhaps not as many usable ones per wafer when first rolled out.  You can pop by DigiTimes for a list of the suppliers TSMC is adopting as well as a bit more detail.

Rumor: Corsair Could Be Purchased for >$500 Million USD

Subject: General Tech | July 19, 2017 - 07:01 AM |
Tagged: corsair

According to Reuters, who claims to have two anonymous sources, Corsair “is in advanced discussions” to be acquired by EagleTree Capital. They claim that the transaction, if it goes through in its current form, will be worth more than $500 million USD. EagleTree has several backers, including Goldman Sachs, Macquarie Group, and BNP Paribas.

corsair-2017-logo.png

From my perspective, this would be an interesting transaction. The company, being private, hasn’t published their finances recently, but annual revenue was as high as $455 million in 2011. Their catalog has since diversified heavily, especially with their seemingly successful power supply, case, and liquid cooling product lines. At first, the rumor felt a little high, because half-of-a-billion dollars is a lot of money, but they’re certainly selling a lot of stock. At the same time, they don't do a lot of their own production, but they do spend a lot of effort in their designs and making them fit a unique niche in one way or another.

It has been a few months since Al looked at Intel's Optane and its impressive performance and price.  This is why it seems appropriate to revist the 2280 M.2 stick with a PCIe 3.0 x2 interface.  It is not just the performance which is interesting but the technology behind Optane and the limitations.  For anyone looking to utilize Optane is is worth reminding you of the compatibility limitations Intel requires, only Kaby Lake processors with Core i7, i5 or i3 heritage.  If you do qualify already or are planning a system build, you can revisit the performance numbers over at Kitguru.

As with the previous model, HyperX has chosen a metal body for the Alloy Elite.  This one is larger than that model, at 17.5" x 6.6" which leaves space for a light bar containing 18 red LEDs as well as media keys.  HyperX offers you the choice between MX Blue, Brown, or Red switches, optional silvery WASD keycaps and a removable wrist rest.  The Tech Report had a good experience with the keyboard, however if you consider custom macros, profiles, and lighting features to be critical then perhaps this board is not for you.

Google Glass is back, but this time the users should be safely contained in manufacturing facilities and corporate buildings.  The initial launch lead to what many felt was a breach of public etiquette as there were many people who did not like the idea of being recorded with the AR glasses.  The new incarnation, Glass Enterprise Edition has an improved 8MP camera and a new red light that turns on when the glasses are recording video.  The WiFi bandwidth has been increased but Alphabet has not yet released the technical specifications publicly.  The Inquirer has a bit more information but nothing on the price, you will need to negotiate with Alphabet or one of it's partners to find that out, but you can expect it to be similar to the price of Microsoft's HoloLens.

Rumor: Intel to Launch Quad Core Kaby Lake-R CPUs for Ultraportables

Subject: Processors, Mobile | July 17, 2017 - 04:32 PM |
Tagged: ultrabook, quad core, Intel, i5-8520u, i5-7200u, hyperthreading, dell xps 13, acer swift 3, 15w

A few days ago, laptopmedia.com uncovered some listings for an unannounced revision to the Acer Swift 3 notebook.

swift-3.jpg

In addition to the new Pascal-based NVIDIA MX150 GPU announced just before Computex, astute readers will also spot an unannounced CPU from Intel – the Core i5-8250U. While the model number itself doesn't tell us much other than it's a next generation CPU, the description in the Acer product listings notes it as a quad core CPU.

Following Intel's history with the U-series parts, the 8250U would traditionally be a 15W, dual core CPU with hyperthreading enabled, with the true quad core parts starting with the 35W TDP options

We've had an indication that a quad core U-series processor was coming in the second half of this year from Intel's performance claims presented at Computex this year, but we weren't quite sure what form it would take.

Doing some additional research, we can see several results from this processor in the Geekbench database from various notebook manufacturers – including devices we would expect to be refreshed like the Dell XPS 13 and ASUS Zenbook UX490.

8250u-geekbench.png

From the Geekbench results of the XPS 13 with the i5-8520U compared to the current generation i5-7200U, we see a 54% increase in multi threaded CPU performance while only a 7% increase in single threaded performance. Keep in mind that these leaked benchmarks should be taken with a grain of salt, but we would be very impressed with these numbers in a shipping notebook.

Geekbench's processor profiler also reveals the i5-8250U to be a 4 core/8 thread processor, pointing to hyperthreading being enabled on the i5 processors as well as the i7's, like we currently see in the U-series.

kaby-lake-r.jpg

Some people have been theorizing that this 8000 series processor is from the upcoming Coffee Lake release. However, based on some of the Intel roadmap leaks from late last year, I think that this is actually a Kaby Lake-R CPU. The leaked roadmap suggests that Kaby Lake-R will launch as the 8th generation processor family, to be released in the second half of 2017.

Either way, I am excited to finally see some push forward in the 15W CPU space, which I consider to be the sweet spot between battery life and performance for most users.

Stay tuned for more information on these new Intel processors and these new notebooks as we get out hands on them!

Counting Cores ... Intel on the Bench

Tagged: Intel, i7-7700k, i7-7800x, kaby lake, skylake-x

There is a $50 difference in price between these two chips, $390 versus $340, which will be within the price range of many of enthusiasts.  The i7-7700K's cores run at a higher frequency but there are only four whereas the i7-7800X has a half dozen.  The memory configuration is also a factor, with the Skylake chip offering quad channel memory while the Kaby Lake only offers dual channel.  The size of the cache may not have a huge impact on gaming performance but you need to consider the number of PCIe lanes; is 16 sufficient or will you need 28?

Techspot seeks to answer this question with a large number of gaming benchmarks, including PlayerUnknown's Battlegrounds.

"Although we consider the Ryzen 5 1600 to be the sweet spot for building a new high-end gaming rig, many of you interested in going Intel want to know whether it makes more sense to buy the Core i7-7700K or the new 7800X?"
