During CES we saw a demonstration of a new genre of processor cooling that truly wowed me. That is tough to do - heatsinks and even self-contained water blocks appear to be a dime a dozen these days. Cooler Master has partnered with CoolChip technologies, a start up that promises to make processor cooling more efficient, 2x smaller and quieter too. The secret is kinetic cooling.

coolchip-1.jpg

Kinetic cooling works by removing the typical fan in a heatsink design and replacing it with a piece of rotating metal. This top metal has fins that resemble that of traditional fans that move air UP and away from the heatsink assembly. These fins are mated with a cooling plate, a base piece of metal that comes in contact with the processor and transfers the heat away.

The key is the connection between the top and bottom metal: using a very thin layer of air that resides between a set of interlocking grooves, the small motor in the center of the cooler spins the groves inside each other without touching, drawing heat from the stationary portion to the rotating one.

This is a prototype of a hybrid cooler combining heatpipes and CoolChip

The result is a cooler that is just as efficient as today's but can be small and generate less noise. Because the top half of the heatsink is actually rotating to provide air movement, you no longer need a fan, lowering z-height. And because you are halving the number of places air is making contact (just fan blades versus fan blades and heatsink fins), sound levels are significantly lower for similar TDPs.

Oh and they look damn cool too. CoolChip says that pricing and build cost will be in line with current heatsinks, alleviating worries of high prices.

Check out the video we did with CoolChip for a demonstration!

CES 2015: MediaTek MT2601 Low-Power SoC for Wearables

Subject: General Tech, Processors, Mobile, Shows and Expos | January 7, 2015 - 08:04 PM |
Tagged: smartwatch, mt2601, mediatek, ces 2015, CES

When you start getting into the wearables market, even mobile SoCs can be somewhat big and power-hungry. As such, we are seeing more innovation in processors that satisfy these lower classes (which could just be us paying more attention). The MediaTek MT2601 is one such device, which combines a pair of ARM Cortex-A7 cores (1.2 GHz) with an ARM Mali 400MP GPU (intended frequency unknown) on a package PCB that is less than 480mm2. (Edit @ 9:48PM -- they seem to mean the SoC and other chips, like the Bluetooth module)

mediatek.jpg

MediaTek's release does not list fab nodes, but PDAdb.net claims that it is designed for 28nm.

Of course, these chips are designed to be low cost, low power, and whatever performance can be squeezed out of those two requirements, so it might not be the most interesting SoC that we can talk about. Still, battery life has been a major hindrance to smart watches and other small, niche devices. It will be interesting to see new-generation devices that use these components.

Heck, if I had more time, I might even want to hack around with these directly.

CES 2015: ASUS 27-inch ROG Swift PG27AQ 4K Gaming Monitor with NVIDIA G-SYNC and IPS

Subject: Displays | January 7, 2015 - 03:17 AM |
Tagged: ROG Swift, ROG, monitor, ips, in plane switching, gaming monitor, g-sync, ces 2015, CES, asus

UPDATE: Hands on video with JJ from ASUS!

The new ASUS ROG Swift PG27AQ features a 3840 x 2160-pixel 4K (UHD) resolution IPS panel for wide viewing angles and accurate color.

ROG_Swift_PG27AQ_01.jpg

The 27-inch LED-backlit display features NVIDIA G-SYNC technology to synchronizes its refresh rates to the computer’s graphics-processing unit (GPU), eliminating screen tearing and minimizing stutter and input lag to deliver the smoothest gaming experience possible. The Swift PG27AQ also includes a five-way navigation joystick to navigate the on-screen display (why not, it’s a gaming monitor after all). The monitor stand features full tilt, swivel, pivot and height adjustment, as well as a “smart cable-management system”.

ROG_Swift_PG27AQ_02.jpg

The panel has a 1000:1 contrast ratio (without dynamic numbers in the millions this might look unimpressive, but it is typical for the native contrast on IPS) and 300 cd/m² brightness. The design also features a “super narrow” bezel which looks cool, but also makes multi-monitor setups more seamless (naturally you’ll want to buy at least two, right?).

No word on availability or pricing just yet.

CES 2015: AMD Talks Technical about FreeSync Monitors

Subject: Graphics Cards, Displays, Shows and Expos | January 7, 2015 - 03:11 AM |
Tagged: video, radeon, monitor, g-sync, freesync, ces 2015, CES, amd

It finally happened - later than I had expected - we got to get hands on with nearly-ready FreeSync monitors! That's right, AMD's alternative to G-Sync will bring variable refresh gaming technology to Radeon gamers later this quarter and AMD had the monitors on hand to prove it. On display was an LG 34UM67 running at 2560x1080 on IPS technology, a Samsung UE590 with a 4K resolution and AHVA panel and BenQ XL2730Z 2560x1440 TN screen.

free-1.jpg

The three monitors sampled at the AMD booth showcase the wide array of units that will be available this year using FreeSync, possibly even in this quarter. The LG 34UM67 uses the 21:9 aspect ratio that is growing in popularity, along with solid IPS panel technology and 60 Hz top frequency. However, there is a new specification to be concerned with on FreeSync as well: minimum frequency. This is the refresh rate that monitor needs to maintain to avoid artifacting and flickering that would be visible to the end user. For the LG monitor it was 40 Hz.

free-3.jpg

What happens below that limit and above it differs from what NVIDIA has decided to do. For FreeSync (and the Adaptive Sync standard as a whole), when a game renders at a frame rate above or below this VRR window, the V-Sync setting is enforced. That means on a 60 Hz panel, if your game runs at 70 FPS, then you will have the option to enable or disable V-Sync; you can either force a 60 FPS top limit or allow 70 FPS with screen tearing. If your game runs under the 40 Hz bottom limit, say at 30 FPS, you get the same option: V-Sync on or V-Sync off. With it off, you would get tearing but optimal input/display latency but with it off you would reintroduce frame judder when you cross between V-Sync steps.

There are potential pitfalls to this solution though; what happens when you cross into that top or bottom region can cause issues depending on the specific implementation. We'll be researching this very soon.

free-3.jpg

Notice this screen shows FreeSync Enabled and V-Sync Disabled, and we see a tear.

FreeSync monitors have the benefit of using industry standard scalers and that means they won't be limited to a single DisplayPort input. Expect to see a range of inputs including HDMI and DVI though the VRR technology will only work on DP.

We have much more to learn and much more to experience with FreeSync but we are eager to get one in the office for testing. I know, I know, we say that quite often it seems.

CES 2015: Intel Compute Stick Runs Windows for $149

Subject: Systems, Shows and Expos | January 7, 2015 - 12:56 AM |
Tagged: x86, Raspberry Pi, Intel, compute stick, chromecast, ces 2015, CES, atom

The Chromecast (and its open siblings) and the Raspberry Pi are interesting devices because they shrunk our concept of a compute device, which put them into new roles. Whether it is streaming media to your TV or controlling electronics on a high altitude balloon, you can use a full computer to do it. Full computers in new roles sound exactly like something Intel wants to research into lately.

intel-stick-01.png

The Intel Compute Stick, aptly named, seems to fit somewhere between these two devices. It is an HDMI dongle enclosing an x86, quad-core, computer with 2GB of RAM and 32GB of internal storage. Intel eventually plans to have the device powered by the HDMI port, but it currently requires power over micro USB. Besides power, it also has a standard USB (Type A-Female) port and a micro SD card slot. It also has 802.11n wireless networking inside it. Being a full Windows device, you can stream media, browse the web, and use many other applications on it.

intel-stick-02.JPG

The Intel Compute Stick with Windows will cost $149, which is significantly more than either a Chromecast or a Raspberry Pi. A Linux version, with 1GB of RAM (half of the Windows version) and 8GB of storage (a quarter of the Windows version), but at a significantly lower price of $89.

CES 2015: EVGA Teases New NVIDIA GeForce GTX 980 with AIO Liquid Cooling

Subject: Graphics Cards | January 6, 2015 - 11:30 PM |
Tagged: nvidia, liquid cooler, GTX 980, gpu cooler, gpu, evga, ces 2015, CES, AIO

EVGA has posted a photo on Twitter of a new GTX 980 with an integrated AIO liquid cooler.

GTX_980_HC_AIO.jpg

The pic is captioned "GTX 980 HC AIO", which indicates that it will join the EVGA GTX 980 Hydro Copper (which carries an MSRP as $799) as a liquid-cooled option in their lineup. The big advantage here, however, is that AIO setup dangling off the back of the card. One free (120mm?) fan opening is all you'd need to be up and running without any extra work.

Of course, you could always buy yourself a suitcase full of AIO liquid-cooled GTX 980's for a cool $2999 if you don't want to wait for this EVGA option.

wf-1.jpg

Triple SLI + AIO liquid cooling = suitcase?

We'll post news of this (seemingly) upcoming EVGA product once details are revealed.

CES 2015: Intel Introduces NUC Hardware with 5th Generation Processors - Broadwell Arrives

Subject: Systems | January 6, 2015 - 08:09 PM |
Tagged: nuc, intel core, Intel, ces 2015, CES, Broadwell

Intel has announced new NUC units with 5th generation Intel Core processors and a dizzying array of complex model names.

nuc_family.png

It comes as no surprise that Intel's NUC lineup hs been upgraded to their newest 5th generation Core architecture, and these new units are powered by Core i3 and i5 Broadwell CPUs. The move to Broadwell will enable these new NUCs to operate with greater efficiency and lower power consumption, an especially vital advantage for systems housed in enclosures as small as 115mm x 111mm x 48.7mm (4.53" x 4.37" x 1.92"). There are a variety of new models to choose from, and Intel is highlighting specific usage examples to aid in the buying decision.

nuc_01.png

The featured NUC, memorably named NUC5i5RYH, is powered by the Core i5 5250U CPU which offers dual-core, 4-thread performance up to 2.7 GHz and supports 2.5" hard drives. Graphics are handled by the integrated Intel HD 6000 GPU which offers multi-display support via Mini DisplayPort (1.2) and Mini HDMI (1.4a). This model supports up to 16GB dual-channel DDR3L memory via two SoDIMM slots, with connectivity provided by Intel PRO Gigabit Ethernet and Intel Wireless-AC 7265.

Storage options for the NUC5i5RYH include M.2 (x4) and SATA 6.0 Gb/s for a SSD/HDD up to 9.5mm thick.

nuc_02.png

The NUC5i5RYH is joined by the NUC5i5RYK, NUC5i3RYH, NUC5i3RYK... Actually, just follow the link to see a comparison of the new Broadwell NUCs.

The new Broadwell NUCs will be shipping in February and March, depending on model.

CES 2015: Calyx Audio PaT USB DAC and Headphone Amp for PC and Mobile

Subject: General Tech | January 6, 2015 - 06:51 PM |
Tagged: mobile, headphone amplifier, DAP, DAC, ces 2015, CES, audiophile, audio

For the audio enthusiasts at CES this year Calyx Audio (Korean maker of audiophile-grade audio components) has a new prototype to show along with last year's Calyx M music player, and for an audiophile product the pricing is very aggressive.

calyx_pat_1.png

Render of the Calyx PaT (dimensions in mm)

The PaT is a similar product in some ways as Calyx Audio's existing $199 USB DAC called the "Coffee", but this unit will be much smaller and will cost half as much at $99. And the reduction in price and size is only half of the story as the PaT also works with mobile devices as an outboard DAC/headphone amp. Apple iPhones and iPads will be supported, and Android devices with USB audio-out support as well (probably via USB OTG).

The PaT supports up to 16-bit, 48kHz files (AIF, M4A, PCM, OGG, and MP3) and will also control track playback and volume via hardware control buttons on the unit. The PaT requires no external power or battery, taking what little juice it needs directly from the connection to your mobile device. As for amplification, in typical Calyx fashion even this miniature board is using a discrete class A/B headphone amplifier. Since the PaT relies only on the power passed through the USB connection it is only capable of outputting 0.8 V, which by comparison is slightly lower than an iPhone 5 which outputs about 0.9 - 1.0 V.

calyx_pat_2.JPG

The tiny prototype PaT in action

The PaT may be just a working board at this point, but the company has scheduled the release for February 2015, when the devices will be available in various colors of thin aluminum enclosures.

In the world of computer audio much more attention has been focused lately on advancements in sound, with special shielding and isolation on motherboards, special gold-plated USB ports for DACs, and customizable op-amps a trend. While the market for dedicated sound cards isn't what it once was, high-end PCI-E and USB cards from Creative (Sound Blaster) and ASUS (Xonar) are still widely available. Most of these products are for desktop users, but there is a growing number of portable devices that allow mobile users to experience great sound, too. For myself, great sound means faithful reproduction of 2-channel music, and it's nice to see attention paid to that area without the added effects of digital signal processing (DSP). Calyx seems interested only in engineering products that play back music as close to the source as possible, and I can't argue with that!

The Calyx PaT is scheduled to launch in February for $99, but like most high-end audio components it will take a little research to track it down. The USA distributor of the Calyx brand has a website with product and contact information here.
