Nearly two years ago, NVIDIA unleashed the Jetson TK1, a tiny module for embedded systems based around the company's Tegra K1 "super chip." That chip was the company's first foray into CUDA-powered embedded systems capable of machine learning including object recognition, 3D scene processing, and enabling things like accident avoidance and self-parking cars.

Now, NVIDIA is releasing even more powerful kit called the Jetson TX1. This new development platform covers two pieces of hardware: the credit card sized Jetson TX1 module and a larger Jetson TX1 Development Kit that the module plugs into and provides plenty of I/O options and pin outs. The dev kit can be used by software developers or for prototyping while the module alone can be used with finalized embedded products.


NVIDIA foresees the Jetson TX1 being used in drones, autonomous vehicles, security systems, medical devices, and IoT devices coupled with deep neural networks, machine learning, and computer vision software. Devices would be able to learn from the environment in order to navigate safely, identify and classify objects of interest, and perform 3D mapping and scene modeling. NVIDIA partnered with several companies for proof-of-concepts including Kespry and Stereolabs.

Using the TX1, Kespry was able to use drones to classify and track in real time construction equipment moving around a construction site (in which the drone was not necessarily programmed for exactly as sites and weather conditions vary, the machine learning/computer vision was used to allow the drone to navigate the construction site and a deep neural network was used to identify and classify the type of equipment it saw using its cameras. Meanwhile Stereolabs used high resolution cameras and depth sensors to capture photos of buildings and then used software to reconstruct the 3D scene virtually for editing and modeling. You can find other proof-of-concept videos, including upgrading existing drones to be more autonomous posted here.

From the press release:

"Jetson TX1 will enable a new generation of incredibly capable autonomous devices," said Deepu Talla, vice president and general manager of the Tegra business at NVIDIA. "They will navigate on their own, recognize objects and faces, and become increasingly intelligent through machine learning. It will enable developers to create industry-changing products."

But what about the hardware side of things? Well, the TX1 is a respectable leap in hardware and compute performance. Sitting at 1 Teraflops of rated (FP16) compute performance, the TX1 pairs four ARM Cortex A57 and four ARM Cortex A53 64-bit CPU cores with a 256-core Maxwell-based GPU. Definitely respectable for its size and low power consumption, especially considering NVIDIA claims the SoC can best the Intel Skylake Core i7-6700K in certain workloads (thanks to the GPU portion). The module further contains 4GB of LPDDR4 memory and 16GB of eMMC flash storage.

In short, while on module storage has not increased, RAM has been doubled and compute performance has tripled for FP16 compute performance and jumped by approximately 40% for FP32 versus the Jetson TK1's 2GB of DDR3 and 192-core Kepler GPU. The TX1 also uses a smaller process node at 20nm (versus 28nm) and the chip is said to use "very little power." Networking support includes 802.11ac and Gigabit Ethernet. The chart below outlines the major differences between the two platforms.

  Jetson TX1 Jetson TK1
GPU (Architecture) 256-core (Maxwell) 192-core (Kepler)
CPU 4 x ARM Cortex A57 + 4 x A53 "4+1" ARM Cortex A15 "r3"
eMMC 16 GB 16 GB
Compute Performance (FP16) 1 TFLOP 326 GFLOPS
Compute Performance (FP32) - via AnandTech 512 GFLOPS (AT's estimation) 326 GFLOPS (NVIDIA's number)
Manufacturing Node 20nm 28nm
Launch Pricing $299 $192

The TX1 will run the Linux For Tegra operating system and supports the usual suspects of CUDA 7.0, cuDNN, and VisionWorks development software as well as the latest OpenGL drivers (OpenGL 4.5, OpenGL ES 3.1, and Vulkan).

NVIDIA is continuing to push for CUDA Everywhere, and the Jetson TX1 looks to be a more mature product that builds on the TK1. The huge leap in compute performance should enable even more interesting projects and bring more sophisticated automation and machine learning to smaller and more intelligent devices.

For those interested, the Jetson TX1 Development Kit (the full I/O development board with bundled module) will be available for pre-order today at $599 while the TX1 module itself will be available soon for approximately $299 each in orders of 1,000 or more (like Intel's tray pricing).

With CUDA 7, it is apparently possible for the GPU to be used for general purpose processing as well which may open up some doors that where not possible before in such a small device. I am interested to see what happens with NVIDIA's embedded device play and what kinds of automated hardware is powered by the tiny SoC and its beefy graphics.

Asus Lights Up Budget Skylake With New B150 Pro Gaming D3 Motherboard

Subject: Motherboards | November 11, 2015 - 08:07 PM |
Tagged: Skylake, Intel Skylake, Intel B150, asus

Asus has a bright new option for budget gamers with a Skylake compatible motherboard based around the B150 chipset. The Asus B150 Pro Gaming D3 is a cheaper alternative that sacrifices some expandability while still incorporating several enthusiast-friendly features.

Intel’s B150 chipset is a cheaper alternative to the Z170 which has received a lot more attention this year. 

The Asus B150 Pro Gaming D3 features a LGA 1151 socket ready for up to Core i7 Skylake processors that is powered by the company’s “Digi+” VRMs. On the memory front, Asus has opted for four DDR3 slots supporting up to 64GB dual channel DDR3 modules at 1,866 MHz. This is a departure from most of the Skylake motherboards that have launched this year which use DDR4. Opting for DDR3 means slightly less potential performance but at welcome cost savings.

For storage, this motherboard has six SATA 6Gbps ports and a single M.2 slot for solid state drives (albeit limited to 2 lanes of PCI-E).

Asus B150 Pro Gaming D3 Motherboard With PCI and LED Lighting.png

The lower-left of this budget board is dominated by a slew of expansion slots as well as Asus’ SupremeFX (Realtek ALC1150 codec) audio hardware. The B150 chipset powers a single PCI-E 3.0 x16 slot and the board further includes a second PCI-E 3.0 x16 slot, two PCI-E x1 slots, and two PCI slots for legacy expansion cards. 

To help this board stand out, the company has added LED lighting above the PCI-E slot and along the right edge of the board. These LEDs can be configured as a solid color, to cycle colors, or to respond to changes in CPU temperature or load (which could help accentuate a custom case mod or simply act as more "bling").

Rear I/O is decent with the following options:

  • 2 x PS/2
  • 1 x HDMI
  • 1 x VGA
  • 4 x USB 3.0 (Intel B150)
  • 1 x USB 3.1 Type-A (ASMedia)
  • 1 x USB 3.1 Type-C (ASMedia)
  • 1 x Gigabit Ethernet (Intel)
  • 5 x Analog audio (300 ohm headphone support, Realtek codec)
  • 1 x S/PDIF

There are some limitations with this board, however. The major downgrade from Z170 to B150 is the number of PCI Express lanes from 20 on Z170 to 8 with B150. As such, when using the second physical x16 slot (max electrical x4) with a x4 or faster device the two physical x1 slots will be disabled. Further, when using the M.2 slot for your SSD in SATA mode, one of the physical SATA ports will be disabled. There is only so much bandwidth to go around here as well as the loss of overclocking ability with the cheaper chipset.

Naturally, Asus has not released specific pricing or availability for the B150 Pro Gaming D3. Expect it to undercut existing Skylake compatible boards, though. And if you have been thinking about upgrading, this is a cheaper upgrade path (you can re-use your DDR3 memory) that is an alternative to the Biostar board that can support both DDR3 and DDR4.

Thrustmaster Offers T300 Servo Base as a Standalone Product

Subject: General Tech | November 11, 2015 - 06:39 PM |
Tagged: wheel, tx f458, TX, Thrustmaster, T500, T300RS, t300 base, T300, 599XX Alcantara

Seems we have been on a bit of a Thrustmaster kick as of late?  We are not really complaining as there are certainly some interesting products that the company offers.  The latest product is not new, but how it is presented is.  Thrustmaster has traditionally bundled all of the different parts of the wheel together, but for the past few years they have worked on expanding the wheel ecosystem so users can upgrade certain pieces at will.

T300 Servo Base.png

This is all well and good, but users might find that they are throwing their money away by not recycling or reselling the parts they were upgrading.  Bought the TX F458 and want to purchase the shifter?  Go for it, but you need to buy the 3 pedal unit as the F458 kit only includes a two pedal unit.  Upgrade to the leather GT wheel or the new 599XX Alcantara edition?  Might as well throw the stock wheel in the closet, never to be seen again.

Choice is a good thing, so Thrustmaster is now offering its more moderately priced base unit, the T300, as a standalone part.  This will allow users to purchase a good quality base all the while picking and choosing what other components to use.  The base price is $249 US.

The T300 base unit features a strong brushless motor with the dual belt pulley system.  This base unit is an upgrade from the TX base that is included with my previously reviewed TX F458 Italia Edition wheel set.  It features the full 1080 degrees of rotation vs. the TX’s 900 degrees.  The motor also looks to be larger and stronger than the TX.  The base unit is compatible with the PS3/PS4, and the PC.  It also features the H.E.A.R.T sensor that utilizes the Hall Effect to provide a contact-less sensor that should last nearly forever.  It features the 16 bit sensor giving over 65,000 values around the axis.  Xbox 1 users will have to rely on the TX base unit as the T300 is not compatible with that system.

T300 Servo Base Ecosystem.jpg

Thrustmaster's competitor Fanatec has been selling the base units by themselves for quite some time, so it is nice to see Thrustmaster offer customers the same flexibility.  One thing must be noted though, the T300 is significantly less expensive than the lowest priced Fanatec base units that are currently available.

Fallout 4 performance at the high end

[H]ard|OCP tested out the performance of the 980 Ti and FuryX in single card configurations as multiple GPU support is non-existent in Fallout 4, some have had moderate success with workarounds which [H] mentions at the end of the review.  At launch it seems NVIDIA's card offers significantly better performance overall, hopefully that delta will decrease as patches and drivers are rolled out.  As far as features go, enabling godrays has a huge effect on performance for both cards and FXAA is the best performing AA when displaying a wide variety of terrain, close forested areas allowed TAA to narrow the gap.  As to the game itself, as of yet they do not sound overly impressed.


"Fallout 4 is out on the PC, in this preview we will take a look at performance between GeForce GTX 980 Ti and Radeon R9 Fury X as well as some in-game feature performance comparisons. We'll also take a look at some in-game feature screenshots and find out what settings are best for an enjoyable gaming experience."

NVIDIA's new Tesla M40 series

Subject: General Tech | November 11, 2015 - 06:12 PM |
Tagged: nvidia, Tesla M40, neural net, JetsonTX1

There are a lot of colloquialisms tossed about such as AI research and machine learning which refer to the work being done designing neural nets by feeding in huge amounts of data to an architecture capable of forming and weighting connections in an attempt to create a system capable of processing that input in a meaningful way.  You might be familiar with some of the more famous experiments such as Google's Deep Dream and Wolfram's Language
Image Identification Project
.  As you might expect this takes a huge amount of computational power and NVIDA has just announced the Tesla M40 accelerator card for training deep neural nets.  It is fairly low powered at 50-75W of draw and NVIDIA claims it will be able to deal with five times more simultaneous video streams than previous products.  Along with this comes Hyperscale Suite software, specifically designed to work on the new hardware which Jen-Hsun Huang comments on over at The Inquirer.  

At the end of the presentation he also mentioned the tiny Jetson TX1 SoC.  It has 256-core Maxwell GPU capable of 1TFLOPS, a 64-bit ARM A57 CPU, 4GB of memory and communicates via Ethernet or Wi-Fi all on a card 50x87mm (2x3.4)" in size.  It will be available at $300 when released some time early next year.


"Machine learning is the grand computational challenge of our generation. We created the Tesla hyperscale accelerator line to give machine learning a 10X boost. The time and cost savings to data centres will be significant."

Video Perspective: Lenovo Yoga 900 Skylake-powered 2-in-1 Notebook Preview

Subject: Mobile | November 11, 2015 - 03:15 PM |
Tagged: yoga 900, yoga, video, Skylake, Lenovo, Intel

The barrage of Skylake powered notebooks and tablets has begun and the PC Perspective offices are filling to the gills with boxes and samples. I have already previewed the new Microsoft Surface Pro 4 and Surface Book in preparation for our full review, so I thought I would do the same for the Lenovo Yoga 900. This is the first product released as part of a new branding scheme Lenovo has adopted for its flexible notebook line. 


The Lenovo Yoga 900 is a 13-in convertible notebook that can be used in the classic clamshell form factor in addition to the fully collapsed mode to operate as a tablet (and in two other forms). It maintains the same watch bad style hinge that was introduced with the Yoga 3 Pro and starts at $1099 with a Core i7 processor, 8GB of memory, a 3200x1800 resolution touch screen and a 256GB  NVMe SSD. You can find it in orange, gold or silver colors.


Even maxed out with 16GB of memory and a 512GB SSD, the Yoga 900 is quite affordable, at just $1299!

For this generation Lenovo has decided to use the full 15 watt Skylake processor which will improve performance over the Yoga 3 Pro (the previous model) quite dramatically. If you remember back to last year, the Yoga 3 Pro was thinner and lighter than the Yoga 2 Pro but actually took a step backwards in performance (using a Core M processor) and battery life. Lenovo got lots of feedback that users weren't interested in those trade offs and the Yoga 900 is a bit thicker and heavier, but offers better performance and impressive battery life at over 9 hours in our Wi-Fi browsing tests.


Connectivity is decent for a thin and light machine including two USB 3.0 ports, one USB 3.1 port, SD card reader and a combination power port / USB port. That combo port is used to plug in your charger when you are tethered to power or utilize it as an additional USB port for accessories when mobile. 


The keyboard and trackpad are still question marks for me - it definitely doesn't feel like previous Lenovo keyboards, with very little throw a requirement to fit in this form factor. I'll give it until we post our full review to really pass judgment.

Basemark GPU Vulkan Announced for Q2'16 Release

Subject: Graphics Cards | November 10, 2015 - 03:02 PM |
Tagged: vulkan

The Vulkan API, announced during the Game Developers Conference last March, is a low-level method to communicate with GPUs. It is essentially a fork of AMD's Mantle, which was modified to include things like OpenCL's SPIR bytecode for its shading and compute language, rather than DirectX and Mantle's HLSL (or OpenGL's GLSL). At the time, Khronos mentioned that Vulkan is expected to be released in 2015, and that they intend to “under promise and over deliver” on that schedule. Being November, I expect that something came up, which isn't too surprising as Microsoft seems to have similar issues with DirectX 12.


That said, Basemark has just announced that they will have (at least one?) Vulkan-compatible benchmark available in Q2 2016. It is unclear whether they mean calendar year or some arbitrary fiscal year. Basemark GPU Vulkan is planned to focus on “relevant Vulkan API performance tests as opposed to theoretical workloads”. This sounds like more than a high-draw, low detail technical demo, which is an interesting metric, but one that will probably be covered elsewhere (like the competing 3DMark from Futuremark).

Hopefully the roll-out, for developers at the very least, will occur this year, though.

It's a huge month for PC gaming with the release of Bethesda's Fallout 4 and EA's Star Wars Battlefront likely to take up hours and hours of your (and my) time in the lead up to the holiday season. NVIDIA just passed over links to its latest "Game Ready" driver, version 358.91.


Fallout 4 is going to be impressive graphically

Here's the blurb from NVIDIA directly:

Continuing to fulfill our commitment to GeForce gamers to have them Game Ready for the top Holiday titles, today we released a new Game Ready driver.  This Game Ready driver will get GeForce Gamers set-up for tomorrow’s release of Fallout 4, as well as Star Wars Battlefront, StarCraft II: Legacy of the Void. WHQLed and ready for the Fallout wasteland, driver version 358.91 will deliver the best experience for GeForce gamers in some of the holiday’s hottest titles.

Other than learning that NVIDIA considers "WHQLed" to be a verb now, this is good news for PC gamers looking to dive into the world of Fallout or take up arms against the Empire on the day of release. I honestly believe that these kinds of software updates and frequent driver improvements timed to major game releases is one of the biggest advantages that GeForce gamers have over Radeon users; though I hold out hope that the red team will get on the same cadence with one Raja Koduri in charge.

Tagged: ROG, Republic of Gamers, Maximus VIII Extreme/Assembly, Matrix GTX 980 Ti, Headphone Amp, E9018K2M, DAC, asus, 10GbE, 10 Gbps Ethernet

ASUS has announced two new products for their Republic of Gamers lineup today, and while we saw the Matrix GTX 980 Ti at IFA in September (and the Maximus VIII Extreme/Assembly was also on display), there are further details for both products in today's press release.


ASUS ROG Maximus VIII Extreme/Assembly motherboard with Matrix 980 Ti

The motherboard in question is the Maximus VIII Extreme/Assembly, a Z170 board with an external headphone amp and 10Gb/s Ethernet add-in card included. This board could run into some money.


The ROG 10G Express expansion card

While other Maximus VIII series motherboards have high-end audio support, the Extreme/Assembly further differentiates itself with an included 10Gb/s Ethernet card. ASUS has partnered with Tehuti Networks for the card, which in addition to 10Gbps also operates at conventional 100/1000 Ethernet speeds, as well as new 2.5/5Gbps over CAT5e.

“ROG 10G Express is the enterprise-speed Ethernet card, powered by Aquantia® and Tehuti Networks: these key partners are both members of the NBASE-T™ alliance, and are working closely to create the new 2.5Gbit/s and 5Gbit/s standards that will be compatible with the existing Category 5e (Cat 5e) cabling and ports. With PCI Express 2.0 x4 speed, it equips Maximus VIII Extreme/Assembly gamers for next-generation LAN speeds of up to 10Gbit/s — or up to ten times (10X) faster than today’s fastest onboard consumer Ethernet.”

This will certainly add to the cost of the motherboard considering a 10GbE card (without the 2.5/5Gbps feature) currently sells for $239.99 on Amazon.


The ROG SupremeFX Hi-Fi amplifier

If you’re an audio enthusiast (like me) you’ll be impressed by the attention to audio, which begins with the audiophile-grade ESS E9018K2M DAC chip found on other members of the Maximus VIII family, and capable of not only native PCM 32-bit/384kHz playback, but up to dual-rate DSD (DSD128). The external headphone amplifier features the Texas Instruments TPA6120A2, and has a very high 6V output to drive the most challenging headphone loads.

What about the Matrix GTX 980 Ti? Full specifications were announced for the card, with boost GPU clock speeds of up to 1317 MHz.


  • Graphics Engine: NVIDIA GeForce GTX 980 Ti
  • Video memory: 6GB GDDR5
  • CUDA cores: 2816
  • GPU clock (boosted):
    • 1317MHz (OC mode)
    • 1291MHz (gaming mode)
  • GPU clock (base)
    • 1216MHz (OC mode)
    • 1190MHz (gaming mode)
  • Memory clock: 7200MHz
  • Memory interface: 384-bit
  • Display Output: 3x DisplayPort 1.2, 1x HDMI 2.0, 1x Dual-link DVI
  • Dimensions: 11.62 x 5.44 x 2 inches

Availability and pricing information for these new ROG products was not released.

AMD will reportedly be launching their latest performance graphics card soon, and specs for this rumored R9 380X have now been reported at VR-Zone (via Hardware Battle).


(Image credit: VR-Zone)

Here are the full specifications from this report:

  • GPU Codename: Antigua
  • Process: 28 nm
  • Stream Processors: 2048
  • GPU Clock: Up to 1000 – 1100 MHz (exact number not known)
  • Memory Size: 4096 MB
  • Memory Type: GDDR5
  • Memory Interface: 256-bit
  • Memory Clock: 5500 – 6000 MHz (exact number not known)
  • Display Output: DisplayPort 1.2, HDMI 1.4, Dual-Link DVI-D

The launch date is reportedly November 15, and the card will (again, reportedly) carry a $249 MSRP at launch.


The 380X would build on the existing R9 285

Compared to the R9 280X, which also offers 2048 stream processors, a boost clock up to 1000 MHz, and 6000 MHz GDDR5, the R9 380X would lose memory bandwidth due to the move from a 384-bit memory interface to 256-bit. The actual performance won’t be exactly comparable however, as the core (Antigua, previously Tonga) will share more in common with the R9 285 (Tonga), though the R9 285 only offered 1792 Stream processors and 2 GB of GDDR5.

You can check out our review of the R9 285 here to see how it performed against the R9 280X, and it will certainly be interesting to see how this R9 380X will fare if these specifications are accurate.

NVIDIA Confirms Clock Speed, Power Increases at High Refresh Rates, Promises Fix

Subject: Graphics Cards | November 6, 2015 - 04:05 PM |
Tagged: ROG Swift, refresh rate, pg279q, nvidia, GTX 980 Ti, geforce, asus, 165hz, 144hz

Last month I wrote a story that detailed some odd behavior with NVIDIA's GeForce GTX graphics cards and high refresh rate monitors, in particular with the new ASUS ROG Swift PG279Q that has a rated 165Hz refresh rate. We found that when running this monitor at 144Hz or higher refresh rate, idle clock speeds and power consumption of the graphics card increased dramatically.

The results are much more interesting than I expected! At 60Hz refresh rate, the monitor was drawing just 22.1 watts while the entire testing system was idling at 73.7 watts. (Note: the display was set to its post-calibration brightness of just 31.) Moving up to 100Hz and 120Hz saw very minor increases in power consumption from both the system and monitor.


But the jump to 144Hz is much more dramatic – idle system power jumps from 76 watts to almost 134 watts – an increase of 57 watts! Monitor power only increased by 1 watt at that transition though. At 165Hz we see another small increase, bringing the system power up to 137.8 watts.

When running the monitor at 60Hz, 100Hz and even 120Hz, the GPU clock speed sits comfortably at 135MHz. When we increase from 120Hz to 144Hz though, the GPU clock spikes to 885MHz and stays there, even at the Windows desktop. According to GPU-Z the GPU is running at approximately 30% of the maximum TDP.

We put NVIDIA on notice with the story and followed up with emails including more information from other users as well as additional testing completed after the story was posted. The result: NVIDIA has confirmed it exists and has a fix incoming!

In an email we got from NVIDIA PR last night: 

We checked into the observation you highlighted with the newest 165Hz G-SYNC monitors.
Guess what? You were right! That new monitor (or you) exposed a bug in the way our GPU was managing clocks for GSYNC and very high refresh rates.
As a result of your findings, we are fixing the bug which will lower the operating point of our GPUs back to the same power level for other displays.
We’ll have this fixed in an upcoming driver.

This actually supports an oddity we found before: we noticed that the PG279Q at 144Hz refresh was pushing GPU clocks up pretty high while a monitor without G-Sync support at 144Hz did not. We'll see if this addresses the entire gamut of experiences that users have had (and have emailed me about) with high refresh rate displays and power consumption, but at the very least NVIDIA is aware of the problems and working to fix them.

I don't have confirmation of WHEN I'll be able to test out that updated driver, but hopefully it will be soon, so we can confirm the fix works with the displays we have in-house. NVIDIA also hasn't confirmed what the root cause of the problem is - was it related to the clock domains as we had theorized? Maybe not, since this was a G-Sync specific display issue (based on the quote above). I'll try to weasel out the technical reasoning for the bug if we can and update the story later!

MSI Z170A Gaming M7, a board nicely balanced in performance and price

Tagged: Z170A Gaming M7, msi, LGA 1151, Intel

At $220 currently the MSI Z170A Gaming M7 sits comfortably between a value board and a flagship model.  The heatsinks not only look good but provide decent cooling as well, as [H]ard|OCP points out in their review.  As far as connectivity goes, this board has a half dozen SATA 6Gbps ports, two SEx ports and two M.2 slots along with a total of seven USB 2.0 ports, six USB 3.0 ports and a pair of USB 3.1 ports, one of which has a Type-C connection.  There are three PCIe 3.0 slots, x16 in design and capable of running x8/x8/x4 when all populated, with another four 1x slots for an impressive total number of slots.  Check out the overclocking performance and the new UEFI which replaces the old Click BIOS in the full review.


"MSI has changed gears as of late vowing to be the number one motherboard manufacturer in the "gaming" segment. While a "gaming" motherboard MSI is still focused on overclocking with this model. We look at the Z170A Gaming M7 to see if it brings MSI one step closer or a step away from that very goal."

You got air in my LiOn battery! Oh wait ...

Subject: General Tech | November 6, 2015 - 12:48 PM |
Tagged: Li-air, battery

Many great discoveries happen accidentally, when a scientist is attempting to create a new material or upgrade an existing one, only to stumble upon something different or to achieve the desired results in an unexpected way.  Such was the case for K M Abraham who was trying to improve the performance of LiOn batteries when one of his batteries sprung a leak and allowed air into the cells.  Over the past twenty years we have barely managed to triple the power of batteries so any advancement in battery technology is welcome even ones which seem at first to have serious drawbacks.  The problem with this particular battery design is in the formation of Li2O2 deposits as the battery discharges which will eventually render the battery nonchargeable and useless.   Read on at The Register to see how that problem has been overcome and the possible uses of this new type battery.


"Rather than try to fix the leak, Abraham investigated and discovered the first rechargeable lithium-air (Li-air) battery. So far this discovery hasn’t led to any technically viable products, but a paper published in Science from a University of Cambridge research group may be about to change that."

GLOBALFOUNDRIES Achieves 14nm FinFET - Coming to New AMD Products

Subject: Processors | November 6, 2015 - 10:09 AM |
Tagged: tape out, processors, GLOBALFOUNDRIES, global foundries, APU, amd, 14 nm FinFET

GlobalFoundries has today officially announced their success with sample 14 nm FinFET production for upcoming AMD products.

GlobalFoundries licensed 14 nm LPE and LPP technology from Samsung in 2014, and were producing wafers as early as April of this year. At the time a GF company spokesperson was quoted in this report at KitGuru, stating "the early version (14LPE) is qualified in our fab and our lead product is yielding in double digits. Since 2014, we have taped multiple products and testchips and are seeing rapid progress, in yield and maturity, for volume shipments in 2015." Now they have moved past LPE (Low Power Early) to LPP (Low Power Plus), with new products based on the technology slated for 2016:

"AMD has taped out multiple products using GLOBALFOUNDRIES’ 14nm Low Power Plus (14LPP) process technology and is currently conducting validation work on 14LPP production samples.  Today’s announcement represents another significant milestone towards reaching full production readiness of GLOBALFOUNDRIES’ 14LPP process technology, which will reach high-volume production in 2016."

GlobalFoundries was originally the manufacturing arm of AMD, and has continued to produce the companies processors since the spin-off in 2012. AMD's current desktop FX-8350 CPU was manufactured on 32 nm SOI, and more recently APUs such as the A10-7850K have been produced at 28 nm - both at GlobalFoundries. Intel's latest offerings such as the flagship 6700K desktop CPU are produced with Intel's 14nm process, and the success of the 14LPP production at GlobalFoundries has the potential to bring AMD's new processors closer parity with Intel (at least from a lithography standpoint).

Report: Unreleased AMD Bristol Ridge SoC Listed Online

Subject: Processors | November 5, 2015 - 09:30 PM |
Tagged: SoC, report, processor, mobile apu, leak, FX-9830PP, cpu, Bristol Ridge, APU, amd

A new report points to an entry from the USB implementors forum, which shows an unreleased AMD Bristol Ridge SoC.

Bristol Ridge itself is not news, as the report at Computer Base observes (translation):

"A leaked roadmap had previously noted that Bristol Ridge is in the coming year soldered on motherboards for notebooks and desktop computers in special BGA package FP4."


(USB.org via Computer Base)

But there is something different about this chip as the report point out the model name FX-9830P pictured in the USB.org screen grab is consistent with the naming scheme for notebook parts, with the highest current model being FX-8800P (Carrizo), a 35W 4-thread Excavator part with 512 stream processors from the R7 GPU core.


(BenchLife via Computer Base)

No details are available other than information from a leaked roadmap (above), which points to Bristol Ridge as an FP4 BGA part for mobile, with a desktop variant for socket FM3 that would replace Kaveri/Godavari (and possibly still an Excavator part). New cores are coming in 2016, and we'll have to wait and see for additional details (or until more information inevitably leaks out).

Update, 11/06/15: WCCFtech expounds on the leak:

“Bristol Ridge isn’t just limited to mobility platforms but will also be featured on AM4 desktop platform as Bristol Ridge will be the APU generation available on desktops in 2016 while Zen would be integrated on the performance focused FX processors.”

WCCFtech’s report also included a link to this SiSoftware database entry for an engineering sample of a dual-core Stoney Ridge processor, a low-power mobile part with a 2.7 GHz clock speed. Stoney Ridge will reportedly succeed Carrizo-L for low-power platforms.

The report also provided this chart to reference the new products:
