A reasonable response about Ryzen, please do not check your sanity at the door

Tagged: amd, Intel, ryzen, sanity check

Ars Technica asks the question that many reasonable people are also pondering, "Intel still beats Ryzen at games, but how much does it matter?".  We here at PCPer have seen the same sorts of responses which Ars has, there is a group of people who had the expectation that Ryzen would miraculously beat any and all Intel chips at every possible task.  More experienced heads were hoping for about what we received, a chip which can challenge Broadwell, offering performance which improved greatly on their previous architecture.  The launch has revealed some growing pains with AMD's new baby but not anything which makes Ryzen bad. 

Indeed, with more DX12 or Vulkan games arriving we should see AMD's performance improve, especially if programmers start to take more effective advantage of high core counts.  Head over to read the article, unless you feel that is not a requirement to comment on this topic.

"In spite of this, reading the various reviews around the Web—and comment threads, tweets, and reddit posts—one gets the feeling that many were hoping or expecting Ryzen to somehow beat Intel across the board, and there's a prevailing narrative that Ryzen is in some sense a bad gaming chip. But this argument is often paired with the claim that some kind of non-specific "optimization" is going to salvage the processor's performance, that AMD fans just need to keep the faith for a few months, and that soon Ryzen's full power will be revealed."

Here Comes the Midrange!

Today AMD is announcing the upcoming Ryzen 5 CPUs.  A little bit was known about them from several weeks ago when AMD talked about their upcoming 6 core processors, but official specifications were lacking.  Today we get to see what Ryzen 5 is mostly about.

ryzen5_01.png

There are four initial SKUs that AMD is talking about this evening.  These encompass quad core and six core products.  There are two “enthusiast” level SKUs with the X connotation while the other two are aimed at a less edgy crowd.

The two six core CPUs are the 1600 and 1600X.  The X version features the higher extended frequency range when combined with performance cooling.  That unit is clocked at a base 3.6 GHz and achieves a boost of 4 GHz.  This compares well to the top end R7 1800X, but it is short 2 cores and four threads.  The price of the R5 1600X is a very reasonable $249.  The 1600 does not feature the extended range, but it does come in at a 3.2 GHz base and 3.6 GHz boost.  The R5 1600 has a MSRP of $219.

ryzen5_04.png

When we get to the four core, eight thread units we see much the same stratification.  The top end 1500X comes in at $189 and features a base clock of 3.5 GHz and a boost of 3.7 GHz.  What is interesting about this model is that the XFR is raised by 100 MHz vs. other XFR CPUs.  So instead of an extra 100 MHz boost when high end cooling is present we can expect to see 200 MHz.  In theory this could run at 3.9 GHz in the extended state.  The lowest priced R5 is the 1400 which comes in at a very modest $169.  This features a 3.2 GHz base clock and a 3.4 GHz boost.

The 1400, 1500, and 1600 CPUs come with Wraith cooling solutions.  The 1600X comes bare as it is assumed that users want to use something a bit more robust.  The R5 1400 comes with the lower end Wraith Stealth cooler while the R5 1500X and R5 1600 come with the bigger Wraith Spire.  The bottom 3 SKUs are all rated at 65 watts TDP.  The 1600X comes in at the higher 95 watt rating.  Each of the CPUs are unlocked for overclocking.

ryzen5_03.png

These chips will provide a more fleshed out pricing structure for the Ryzen processors and provide users and enthusiasts with lower cost options for those wanting to invest in AMD again.  These chips all run on the new AM4 platform which are pretty strong in terms of features and I/O performance.

ryzen5_02.png

AMD is not shipping these parts today, but rather announcing them.  Review samples are not in hand yet and AMD expects world-wide availability by April 11.  This is likely a very necessary step for AMD as current AM4 motherboard availability is not at the level we were expecting to see.  We also are seeing some pretty quick firmware updates from motherboard partners to address issues with these first AM4 boards.  By April 11 I would expect to see most of the issues solved and a healthy supply of motherboards on the shelves to handle the influx of consumers waiting to buy these more midrange priced CPUs from AMD.

What they did not cover or answer would be how the four core products would be presented.  Would each be a single CCX and only 8 MB of L3 cace, or would AMD disable two cores in each CCX and present 16 MB of L3?  We currently do not have the answer to this.  Considering the latency between accessing different CCX units we can surely hope they only keep one CCX active.

ryzen5_05.png

Ryzen has certainly been a success for AMD and I have no doubt that their quarter will be pretty healthy with the estimated sales of around 1 million Ryzen CPUs since launch.  Announcing these new chips will give the mainstream and budget enthusiasts something to look forward to and plan their purchases around.  AMD is not announcing the Ryzen 3 products at this time.

Update: AMD got back to me this morning about a question I asked them about the makeup of cores, CCX units, and L3 cache.  Here is their response.

1600X: 3+3 with 16MB L3 cache. 1600: 3+3 with 16MB L3 cache. 1500X: 2+2 with 16MB L3 cache. 1400: 2+2 with 8MB L3 cache. As with Ryzen 7, each core still has 512KB local L2 cache.

OS Limitations of Vulkan Multi-GPU Support

Subject: Graphics Cards | March 21, 2017 - 07:47 PM |
Tagged: windows 10, vulkan, sli, multi-gpu, crossfire

Update (March 22nd @ 3:50pm EDT): And the Khronos Group has just responded to my follow-up questions. LDA has existed since Windows Vista, at the time for assisting with SLI and Crossfire support. Its implementation has changed in Windows 10, but that's not really relevant for Vulkan's multi-GPU support. To prove this, they showed LDA referenced in a Windows 8.1 MSDN post.

In short:

Vulkan's multi-GPU extensions can be used on Windows 7 and Windows 8.x. The exact process will vary from OS to OS, but the GPU vendor can implement these extensions if they choose, and LDA mode isn't exclusive to Windows 10.

 

Update (March 21st @ 11:55pm EDT): I came across a Microsoft Support page that discusses issues with LDA in Windows 7, so it seems like that functionality isn't limited to WDDM 2.0 and Windows 10. (Why have a support page otherwise?) Previously, I looked up an MSDN article that had it listed as a WDDM 2.0 feature, so I figured DSOGaming's assertion that it was introduced with WDDM 2.0 was correct.

As such, LDA might not require a GPU vendor's implementation at all. It'll probably be more clear when the Khronos Group responds to my earlier request, though.

That said, we're arguing over how much a GPU vendor needs to implement; either way, it will be possible to use the multi-GPU extensions in Windows 7 and Windows 8.x if the driver supports it.

Update (March 21st @ 7:30pm EDT): The Khronos Group has just released their statement. It's still a bit unclear, and I've submit another request for clarification.

Specifically, the third statement:

If an implementation on Windows does decide to use LDA mode, it is NOT tied to Windows 10. LDA mode has been available on many versions of Windows, including Windows 7 and 8.X.

... doesn't elaborate what is required for LDA mode on Windows outside of 10. (It could be Microsoft-supported, vendor-supported, or something else entirely.) I'll update again when that information is available. For now, it seems like the table, below, should actually look something like this:

  Implicit Multi-GPU
(LDA Implicit)
Explicit Multi-GPU
(LDA Explicit)
Unlinked Multi-GPU
(MDA)
Windows 7 Requires GPU Vendor
LDA Implementation?

(Or Equivalent)

LDA Implementation?

(Or Equivalent)
Requires GPU Vendor
LDA Implementation?

(Or Equivalent)
Windows 10
macOS Apple doesn't allow the Vulkan API to ship in graphics drivers.
At all.
Linux / etc.

... but we will update, again, should this be inaccurate.

Update (March 20th @ 3:50pm EDT): The Khronos Group has just responded that the other posts are incorrect. They haven't yet confirmed whether this post (which separates "device groups" from the more general "multi-GPU in Vulkan") is correct, though, because they're preparing an official statement. We'll update when we have more info.

Original Post Below (March 19th @ 9:36pm EDT)

A couple of days ago, some sites have noticed a bullet point that claims Windows-based GPU drivers will need WDDM in “linked display adapter” mode for “Native multi-GPU support for NVIDIA SLI and AMD Crossfire platforms” on Vulkan. This note came from an official slide deck by the Khronos Group, which was published during the recent Game Developers Conference, GDC 2017. The concern is that “linked display adapter” mode is a part of WDDM 2.0, which is exclusive to Windows 10.

This is being interpreted as “Vulkan does not support multi-GPU under Windows 7 or 8.x”.

khronos-2017-vulkan-alt-logo.png

I reached out to the Khronos Group for clarification, but I’m fairly sure I know what this does (and doesn’t) mean. Rather than starting with a written out explanation in prose, I will summarize it into a table, below, outlining what is possible on each platform. I will then elaborate below that.

  Implicit Multi-GPU
(LDA Implicit)
Explicit Multi-GPU
(LDA Explicit)
Unlinked Multi-GPU
(MDA)
Windows 7    
Windows 8.1    
Windows 10
macOS Apple doesn't allow the Vulkan API to ship in graphics drivers.
At all.
Linux / etc.

So the good news is that it’s possible for a game developer to support multi-GPU (through what DirectX 12 would call MDA) on Windows 7 and Windows 8.x; the bad news is that no-one might bother with the heavy lifting. Linked display adapters allow the developer to assume that all GPUs are roughly the same performance, have the same amount of usable memory, and can be accessed through a single driver interface. On top of these assumptions, device groups also hide some annoying and tedious work inside the graphics driver, like producing a texture on one graphics card and quickly giving it to another GPU for rendering.

Basically, if the developer will go through the trouble of supporting AMD + NVIDIA or discrete GPU + integrated GPU systems, then they can support Windows 7 / 8.x in multi-GPU as well. Otherwise? Your extra GPUs will be sitting out unless you switch to DirectX 11 or OpenGL (or you use it for video encoding or something else outside the game).

On the other hand, this limitation might pressure some developers to support unlinked multi-GPU configurations. There are some interesting possibilities, including post-processing, GPGPU tasks like AI visibility and physics, and so forth, which might be ignored in titles whose developers were seduced by the simplicity of device groups. On the whole, device groups was apparently a high-priority request by game developers, and its inclusion will lead to more multi-GPU content. Developers who can justify doing it themselves, though, now have another reason to bother re-inventing a few wheels.

Or... you could just use Linux. That works, too.

Again, we are still waiting on the Khronos Group to confirm this story. See the latest update, above.

Intel Officially Kicks Off Optane Launch with SSD DC P4800X

Tagged: XPoint, SSD DC P4800X, Optane Memory, Optane, Intel, client, 750GB, 3D XPoint, 375GB, 1.5TB

Intel brought us out to their Folsom campus last week for some in-depth product briefings. Much of our briefing is still under embargo, but the portion that officially lifts this morning is the SSD DC P4800X:

Intel_SSD_4800_FlatFront_OnWhite_RGB_Small.jpg

optane-4.png

optane-9.png

MSRP for the 375GB model is estimated at $1520 ($4/GB), which is rather spendy, but given that the product has shown it can effectively displace RAM in servers, we should be comparing the cost/GB with DRAM and not NAND. It should also be noted this is also nearly half the cost/GB of the X25-M at its launch. Capacities will go all the way up to 1.5TB, and U.2 form factor versions are also on the way.

For those wanting a bit more technical info, the P4800X uses a 7-channel controller, with the 375GB model having 4 dies per channel (28 total). Overprovisioning does not do for Optane what it did for NAND flash, as XPoint can be rewritten at the byte level and does not need to be programmed in (KB) pages and erased in larger (MB) blocks. The only extra space on Optane SSDs is for ECC, firmware, and a small spare area to map out any failed cells.

Those with a keen eye (and calculator) might have noted that the early TBW values only put the P4800X at 30 DWPD for a 3-year period. At the event, Intel confirmed that they anticipate the P4800X to qualify at that same 30 DWPD for a 5-year period by the time volume shipment occurs.

Read on for more about the SSD DC P4800X (and other upcoming products!)

LG 32UD99: FreeSync, 4K, and HDR (95% DCI-P3) for $999

Subject: Displays | March 18, 2017 - 12:15 AM |
Tagged: LG, hdr10, hdr

There’s a lot of interesting elements to this monitor. Apart from the refresh rate, which I believe is 60 Hz, it checks off basically every nice-to-have that I can think of... at least for AMD users. It is borderless on all four sides. It has 95% coverage of DCI-P3, which might even be factory-calibrated (if I understand the “Color Calibrated” specification correctly). It also has FreeSync to make gaming at 4K slightly more smooth if you’re just a bit below 60 FPS.

lg-2017-32ud99.jpg

And, according to B&H Photo (via The Verge), it will be coming on the 28th for $999.

It even includes a $100 B&H Gift Card at that price, too!

If you are into printed content production, then you might want to verify its Adobe RGB compatibility before making your purchase. DCI-P3 and Adobe RGB are both fairly large color spaces, but they deviate from each other. (Apparently, DCI-P3 covers more of the red end, while Adobe RGB covers more of the green.) Adobe RGB, if I understand correctly, extended sRGB into a space that printers could be calibrated into, while DCI-P3 is more for HDR video.

Personally, I find 60 Hz mouse pointers to be very noticeable and distracting. As such, the low refresh rate might be a deal-breaker for someone like me, but pretty much everything else looks like a win -- including the ever-important price and availability.

Microsoft is making friends again, no new Win 7/8 updates for new chips

Subject: General Tech | March 17, 2017 - 01:11 PM |

KB4012982 describes the error you will see if you attempt to update Windows 7 or 8.x on 7th generation Intel processors, AMD Bristol Ridge and newer or Qualcomm "8996" and more recent models.  Microsoft has implemented the hardware based obsolescence which they had discussed several months ago when they stated that new chips would need Windows 10 to run.  This move will of course be heralded as brilliant and no one could possibly find this upsetting in the least, especially not in this Reddit thread.  It is a good thing Microsoft does not have a near monopoly in the market and that anyone who does not support this decision can choose from a wide variety of easily implemented alternatives.

Expect there to be workarounds, the vast majority of Enterprise customers have no interest in moving their infrastructure to Windows 10, nor the budget available to do so if they wanted.

Is 240 Hertz SWIFT enough for you? The new ASUS ROG gaming monitor

Subject: Displays | March 20, 2017 - 01:25 PM |
Tagged: tn monitor, SWIFT PG258Q, gsync, ASUS ROG, 1080p

As we wait for connectivity and GPU horsepower to catch up to the new technology available in monitors, those who are upgrading face a choice.  If you want incredibly high refresh rates then you have to sacrifice resolution, whereas if 4K is your need then you will have to be satisfied with lower refresh rate ranges.  The ASUS ROG SWIFT PG258Q is one of the former, offering 1080p resolution but with G-SYNC capable of a refresh rate reaching 240Hz.  That extremely high refresh rate also requires the use of a TN panel, so if you prefer 4k IPS then this display is not the one you are looking for. 

Kitguru provides a full review of the monitor here, including a look at the new style of asymmetrical ROG stand which can tilt farther than you might think at first glance.

"Gaming monitors are clearly going through a bit of a growth spurt, and ASUS is a company particularly focusing on this area. The ROG SWIFT PG258Q is a 24.5in screen with a whopping 240Hz top refresh and NVIDIA G-Sync, plus a host of other features specifically tailored for serious gamers."

BitFenix Releases the Portal: A Sleek Mini-ITX Enclosure

Subject: Cases and Cooling | March 16, 2017 - 09:34 AM |
Tagged: small form factor, SFX, SFF, Portal, mini-itx, enclosure, case, bitfenix, aluminum

BitFenix has announced the Portal, which is one of the more interesting-looking chassis designs to hit the market in recent memory. Available in both black and white, and with or without a top-mounted window to show off your GPU (thanks to the inverted motherboard layout), the Portal is a sleek mini-ITX enclosure with a smooth, rounded aluminum exterior that is certainly a departure from typical case designs.

portal-masterimage.jpg

One of the design concepts made possible by SFX power supplies is a slimming down of the standard tower concept, which leaving component layout identical. In the case of this mini-ITX mini tower case from BitFenix, you might at first think you are looking at a larger case, but that PSU opening is in fact SFX, and the case is just wide enough to accommodate a standard PCIe graphics card.

portal_ww2.jpg

A smaller mini-ITX case is often more challenging to work in, but here BitFenix has a clever solution with their dual-frame design:

"Designed for ITX Motherboards, the striking key component of the interior is the Dual Frame Design for easy access and quick installation. The inner chamber, equipped with enough space for high-end components, slides into the housing via a ball bearing runner design."

portal_bw2.jpg

The external housing slimply slides off to reveal a standard chassis frame, allowing for easy component installation. Beyond the requirements of mini-ITX motherboard and SFX power supply, the Portal allows for CPU coolers of up to 125 mm, and full size graphics cards up to 300 mm long.

Specifications:

  • Chassis Type: ITX Chassis
  • Colors: Black | White
  • Materials: Aluminum | SECC Steel | ABS | Transparent acrylic
  • Motherboard: Mini-ITX
  • CPU Cooler: Up to 125mm height
  • Graphic Card Length: Up to 300mm
  • Power Supply: SFX Form Factor
  • Storage Capacity: 3.5" HDD x2, 2.5" HDD 1+2
  • Cooling Capacity: Front 120mm x1 (included), rear 80mm x1 (included)
  • Radiator Capacity: (Front) Up to 120mm x1
  • Front I/O ports: USB 3.0 x2 | HD Audio Mic & Headphone
  • Dimensions (with stand): (WxHxD) 247 x 395 x 411 mm (9.72 x 15.55 x 16.18 inches)
  • Weight: 5.81 kg (12.81 lbs)

portal_bw1.jpg

Cooling is another area that has received BitFenix's attention, as they have implemented what they call their "intelligent cooling solution" with the Portal:

"To cool the built-in hardware, the portal is equipped with air inlets at all four corners and the bottom of the housing. The air-permeable inner chamber is further equipped with included 120mm intake and 80mm exhaust fan, for a stable airflow for basic Office and Home Theater PCs."

The BitFenix Portal is available now for $139.99 with your choice of color and window option (product pages already up on Newegg.com).

Eurocom's Sky X9E3 Is a Fully Upgradable Gaming Laptop

Subject: Systems, Mobile | March 17, 2017 - 07:21 PM |
Tagged: Sky X9E3, nvidia, notebook, MXM, modular, laptop, Intel Core i7, geforce, gaming, eurocom

Fancy a desktop processor in your laptop? How about dual MXM graphics card slots? While such a machine is likely not as 'portable' as the laptop designation would make it seem, it is interesting to see a notebook product built specifically for upgradability, and that is exactly what Eurocom has done with the Sky X9E3.

m400_1.jpg

"The Sky X9E3 is an SLI Ready and VR capable super high-performance supercomputer laptop. With an upgradeable desktop CPU and two upgradeable desktop GPUs cooled with high-quality copper heatsinks and IC Diamond thermal paste, and controlled by an unlocked system BIOS for the ultimate in overclocking capability."

One of the things detractors of gaming laptops will point out is the limited lifespan of a product that is often far more expensive than a high-end gaming desktop. Granted, gaming laptops generally do not follow the soldered memory trend from thin-and-light machines, allowing users to swap SODIMMs for more memory down the road, and storage is generally upgradable as well. But what about the most expensive parts of a laptop, namely CPU and (even more expensive) GPU? The use of desktop CPUs in the X9E3 is novel, and translates to ready availability for future upgrades; but MXM graphics is still a very expensive route, though I have ended up at Eurocom's website when researching MXM GPU upgrades in the past, so they are at least readily available.

m400_12.jpg

What are the specifications? Eurocom sells the machine configured to order, and lists basic specs as follows:

  • Chipset: Intel Z270 Express (Kaby Lake)
  • Processor: socketed desktop LGA1151 CPU, up to Intel i7 7700K
  • Memory: up to 64GB; DDR4-2400/2666/3000/3200; 4 RAM Sockets
  • VGA Technology: NVIDIA Pascal GeForce GTX 1080 8GB DDR5X and GeForce GTX 1070 8GB DDR5; single or Dual SLI; two MXM 3.0 slots; up to 190W per slot
  • Display Technology: supports total of 4 displays including LCD via 2x DP 1.3, 1x HDMI 2.0 and 1x HDMI 2.0 or DP1.2 (via USB 3.1 type C port); Nvidia Surround View
  • Storage: up to 14TB or storage with 5 drives; 2x HDD/SSD (SATA3) + 3x M.2 PCIe Gen3 x4/SATA3; RAID 0/1/5; supports NVMe SSDs
  • Communications: two 1GbE Killer E2400 RJ45 ports + M.2 WLAN/Bluetooth; Killer DoubleShot X3
  • Operating Systems: Microsoft Windows: 10, 8.1 and 7
  • Card Reader: 6-in-1 MMC/RSMMC/SD/miniSD/SDHC/SDXC up to UHS-II
  • Keyboard: Illuminated, backlit with customizable 7-colours
  • Security: TPM 2.0, Fingerprint and Kensington Lock
  • Audio System: Sound Blaster X-Fi MB5; external 7.1CH audio output; headphone out, microphone in, S/PDIF and Line-in port; two built-in FOSTER Speakers (2W)+ Subwoofer (2.5W)
  • Ports: 2x USB 3.1 type C (HDMI 2.0/DP 1.3/Thunderbolt 3); 2x miniDP 1.3; 1x HDMI 2.0; 5x USB 3.0 (1x Powered USB AC/DC); S/PDIF; Headphone; Mic; Line-in; 2x RJ45 (LAN)
  • Weight and dimensions: 5.5kg / 12.1lbs; WxDxH 428x308x47.2mm / 17.12x12.32x1.88-inch

m400_11.jpg

Pricing begins at $2499, which makes this a hefty proposition at the outset. But for someone looking for desktop experience in a notebook, and wants the ability to purchase faster CPUs and GPUs down the road, it may be worth it.

A new start

Qualcomm is finally ready to show the world how the Snapdragon 835 Mobile Platform performs. After months of teases and previews, including a the reveal that it was the first processor built on Samsung’s 10nm process technology and a mostly in-depth look at the architectural changes to the CPU and GPU portions of the SoC, the company let a handful of media get some hands-on time with development reference platform and run some numbers.

To frame the discussion as best I can, I am going to include some sections from my technology overview. This should give some idea of what to expect from Snapdragon 835 and what areas Qualcomm sees providing the widest variation from previous SD 820/821 product.

Qualcomm frames the story around the Snapdragon 835 processor with what they call the “five pillars” – five different aspects of mobile processor design that they have addressed with updates and technologies. Qualcomm lists them as battery life (efficiency), immersion (performance), connectivity, and security.

slides1-6.jpg

Starting where they start, on battery life and efficiency, the SD 835 has a unique focus that might surprise many. Rather than talking up the improvements in performance of the new processor cores, or the power of the new Adreno GPU, Qualcomm is firmly planted on looking at Snapdragon through the lens of battery life. Snapdragon 835 uses half of the power of Snapdragon 801.

slides2-11.jpg

Since we already knew that the Snapdragon 835 was going to be built on the 10nm process from Samsung, the first such high performance part to do so, I was surprised to learn that Qualcomm doesn’t attribute much of the power efficiency improvements to the move from 14nm to 10nm. It makes sense – most in the industry see this transition as modest in comparison to what we’ll see at 7nm. Unlike the move from 28nm to 14/16nm for discrete GPUs, where the process technology was a huge reason for the dramatic power drop we saw, the Snapdragon 835 changes come from a combination of advancements in the power management system and offloading of work from the primary CPU cores to other processors like the GPU and DSP. The more a workload takes advantage of heterogeneous computing systems, the more it benefits from Qualcomm technology as opposed to process technology.

Need a huge amount of reliable storage? 10TB of enterprise storage from Seagate

The Seagate Barracuda Pro 10TB Enterprise HDD won't give you the fastest access to your data, but if you have a large amount of storage in a reliable format it is worth looking at this review.  The MSRP of $444.45USD is much lower than you would pay for 10TB of SSD storage, though you might be able to set up several smaller disks in a Drobo or similar device for a similar price.  The MTBF is 2.5 million hours, the endurance rating is 550TB per year and there is a 5 year warranty so even with heavy usage you should be able to depend on this drive for quite a long time.  You can drop by NikKTech to see how it performs.

New "Fabric" for ARM

It is not much of a stretch to say that ARM has had a pretty impressive run for the past 10 years since we started paying attention to the company from a consumer point of view.  It took 22 years for ARM to power 50 billion chips that had been shipped.  It took another 4 years to hit the next 50 billion.  Now ARM expects to ship around 100 billion chips in the next four years.
arm_01.png
 
Last year we saw the introduction of multiple technologies from ARM in the shape of the latest Cortex-A CPUs and a new generation of Mali GPUs.  ARM has been near the forefront of applying their designs to the latest, cutting edge process technologies offered by Samsung and TSMC.  This change of pace has been refreshing considering that a few years ago they would announce a new architecture and expect to see it in new phones and devices about 3 years from that point.  Intel attempted a concerted push into mobile and ARM responded by tightening up their portfolio and aggressively pushing release dates.
 
This year appears no different for ARM as we expect new technologies to be announced again later this year that will update their offerings as well as process technology partnerships with the major pure-play foundries.  The first glimpse of what we can expect is ARM's announcement today of their DynamIQ technology.

Ultimate Topre

There are cars that get you from point A to point B, and then there are luxurious grand touring cars which will get you there with power, comfort, and style - for a price. Based on the cost alone ($269.99 MSRP!) it seems like a safe bet to say that the REALFORCE RGB keyboard will be a similarly premium experience. Let’s take a look!

There is as much personal taste at issue when considering a keyboard (or dream car!) as almost any other factor, and regardless of build quality or performance a keyboard is probably not going to work out for you if it doesn’t feel right. Mechanical keyboards are obviously quite popular, and more companies than ever offer their own models, many using Cherry MX key switches (or generic ‘equivalents’ - which vary in quality). Topre keys are different, as they are a capacitive key with a rubber dome and metal spring, and have a very smooth, fast feel to them - not clicky at all.

“Topre capacitive key switches are a patented hybrid between a mechanical spring based switch, a rubber dome switch, and a capacitive sensor which, combined, provide tactility, comfort, and excellent durability. The unique electrostatic design of Topre switches requires no physical mechanical coupling and therefore key switch bounce/chatter is eliminated.”

Tagged: gaming, dx11, dx12

We are finally starting to see a diverse enough field of games capable of running in both DX11 and DX12 which makes it much easier to see performance pattern differences.  [H]ard|OCP tested out Rise of the Tomb Raider, Hitman, Deus Ex: Mankind Divided, BF1, The Division, Sniper Elite and AotS on AMD's RX480 and NVIDIA's GTX 1080 and 1080 Ti.  In almost all cases the difference between the two APIs were negligible and neither offers significant performance benefits to owners of these cards.  The one exception was Sniper Elite 4 which did see some performance deltas, especially on the RX480.  Check out the full review to see for yourself.

"We play latest games with DX12 support and find out which is faster, DX12 or DX11? We use the latest drivers from NVIDIA and AMD to find any advantages in this GPU focused review. We’ll get to the bottom of the question, "Should I be running this game in DX12 or DX11 in order to get the best real world gaming performance?"

Overview

If you look at the current 2-in-1 notebook market, it is clear that the single greatest influence is the Lenovo Yoga. Despite initial efforts to differentiate convertible Notebook-tablet designs, newly released machines such as the HP Spectre x360 series and the Dell XPS 13" 2-in-1 make it clear that the 360-degree "Yoga-style" hinge is the preferred method.

Today, we are looking at a unique application on the 360-degree hinge, the Lenovo Yoga Book. Will this new take on the 2-in-1 concept be so influential?

The Lenovo Yoga Book is 10.1" tablet that aims to find a unique way to implement a stylus on a modern touch device. The device itself is a super thin clamshell-style design, featuring an LCD on one side of the device, and a large touch-sensitive area on the opposing side.

This large touch area serves two purposes. Primarily, it acts as a surface for the included stylus that Lenovo is calling the Real Pen. Using the Real Pen, users can do thing such as sketch in Adobe Photoshop and Illustrator or takes notes in an application such as Microsoft OneNote.

The Real Pen has more tricks up its sleeve than just a normal stylus. It can be converted from a pen with a Stylus tip on it to a full ballpoint pen. When paired with the "Create Pad" included with the Yoga Book, you can write on top of a piece of actual paper using the ballpoint pen, and still have the device pick up on what you are drawing.

The Register posted a cheerful article today, discussing the security of the other Internet of Things, which they have dubbed the Internet of Big Things.  Botnets formed out of compromised toasters, refrigerators and webcams is one thing; taking over power stations and industrial equipment is quite another.  Citizens of the Ukraine know the dangers all too well, having had their power grid taken offline once in 2015 and again more recently by nefarious means.  Take a read through to learn about how vulnerabilities in systems such as the Industrial Control System and Supervisory Control and Data Acquisition could be used to cause significant harm, as well as a search engine reassuringly named Shodan.

"The Internet of Big Things exists because it makes perfect sense to have accessibility to equipment from afar. Industrial systems are complex, specialist items and for many such systems it’s common for there to be only a handful of qualified maintenance staff in the country, continent or world."

A call to ARM in the server room

Subject: General Tech | March 21, 2017 - 12:23 PM |
Tagged: server, SBSA, arm

As we mentioned last week, Qualcomm's new Centriq 2400 Platform will run Microsoft server operating systems on ARM chips, however there are those who believe it is already too late for that to save Microsoft's hold on the data centre.  A few years ago ARM started work on developing what they called Server Base System Architecture, essentially creating a standardized way in which any OS can communicate effectively with an ARM chip, the same sort of standardization which originally won the server room for x86 based chips.  With ARM's DynamIQ Technology, which Josh discusses in depth, just around the corner their hardware is also becoming more attractive.  Pop by The Register for more details on this possible industry sea change.

"Cutting to the heart of it, it doesn't actually matter if Microsoft releases Windows Server for ARM. Windows isn't the future and even Microsoft knows it. The upcoming availability of SQL server on Linux is all the proof we need that the game is over and, in the data centre at least, Microsoft didn't win."

Sprint, Qualcomm, and Motorola Team up to demonstrate Gigabit Class LTE Network in New Orleans

Demoing improvements to mobile phone networks is difficult. Where an individual vendor such as Intel or AMD can show off an improved CPU architecture mostly by themselves, it takes a lot of cooperation between companies to show off advanced mobile data initiatives.

IMG_6524.JPG

This is just what Sprint, Qualcomm, and Motorola teamed up to do last week at the Smoothie King Center in New Orleans, Louisiana.

The first part of the story revolves around Sprint’s unique placement in the US mobile network market.  While network operators such as Verizon, ATT, and T-Mobile in the US currently operate their LTE networks on low and mid-band LTE frequencies, the vast majority of Sprint's allocated frequency into the high-band range of 2.5GHz. The reason that Sprint has this spectrum is from their short-lived rollout of WiMax technology with Clear.

High-band frequencies can provide several advantages when deploying technologies enabling Gigabit-class LTE and on the road to 5G.

First, the antenna size needed in the 2.5GHz range is substantially smaller than the antenna size for a more common LTE frequency like 1900MHz. This means that when looking to deploy cellular sites utilizing technologies like 4X4 MIMO antenna arrays, Sprint can make smaller cell sites and be more nimble by placing them in areas where they are seeing substantial network load.
