Tagged: reeven, Okeanos, Okeanos RC-1402
The Okeanos RC-1402 is a large hunk of metal, standing 140x135x163mm and weighing in at 1145g when both the 12cm and 14cm fans are attached. This makes it just a bit smaller than Morry's beloved Noctua NH-D15, which will allow it to fit into slightly tighter builds. [H]ard|OCP tested it on an i7-4770K and found its performance to be acceptable but not outstanding in any way. Unfortunately, the price does stand out as it costs more than coolers which offer equivalent performance. Drop by for a look at their whole review.
"The Reeven Okeanos RC-1402 is not exactly a new CPU air cooler, but it is not widely available in the United States so it has not gotten a lot of coverage in North America. The cost for the cooler is not low, and two staggered-sized fans are included in the box, so we have fairly high performance expectations for this twin tower cooler."

Qualcomm has announced their first successful 5G New Radio (NR) connection using their prototype sub-6 GHz prototype system. This announcement was followed by today's news of Qualcomm's collaboration with Ericsson and Vodafone to trial 5G NR in the second half of 2017, as we approach the realization of 5G. New Radio is expected to become the standard for 5G going forward as 3GPP moves to finalize standards with release 15.
"5G NR will make the best use of a wide range of spectrum bands, and utilizing spectrum bands below 6 GHz is critical for achieving ubiquitous coverage and capacity to address the large number of envisioned 5G use cases. Qualcomm Technologies’ sub-6 GHz 5G NR prototype, which was announced and first showcased in June 2016, consists of both base stations and user equipment (UE) and serves as a testbed for verifying 5G NR capabilities in bands below 6 GHz."

Qualcomm first showed their sub-6 Ghz prototype this past summer, and it will be on display this week at MWC. The company states that the system is designed to demonstrate how 5G NR "can be utilized to efficiently achieve multi-gigabit-per-second data rates at significantly lower latency than today’s 4G LTE networks". New Radio, or NR, is a complex topic as it related to a new OFDM-based wireless standard. OFDM refers to "a digital multi-carrier modulation method" in which "a large number of closely spaced orthogonal sub-carrier signals are used to carry data on several parallel data streams or channels". With 3GPP adopting this standard going forward the "NR" name could stick, just as "LTE" (Long Term Evolution) caught on to describe the 4G wireless standard.
Along with this 5G NR news comes the annoucement of the expansion of its X50 modem family, first announced in October, "to include 5G New Radio (NR) multi-mode chipset solutions compliant with the 3GPP-based 5G NR global system", according to Qualcomm. This 'multi-mode' solution provides full 4G/5G compatibility with "2G/3G/4G/5G functionality in a single chip", with the first commercial devices expected in 2019.
"The new members of the Snapdragon X50 5G modem family are designed to support multi-mode 2G/3G/4G/5G functionality in a single chip, providing simultaneous connectivity across both 4G and 5G networks for robust mobility performance. The single chip solution also supports integrated Gigabit LTE capability, which has been pioneered by Qualcomm Technologies, and is an essential pillar for the 5G mobile experience as the high-speed coverage layer that co-exists and interworks with nascent 5G networks. This set of advanced multimode capabilities is designed to provide seamless Gigabit connectivity – a key requirement for next generation, premium smartphones and mobile computing devices."

Qualcomm has announced the Snapdragon X20 LTE modem, their 2nd-generation Gigabit LTE solution built on 10nm FinFET and offering what Qualcomm says are “a number of industry firsts”, which include first to Category 18 (downlink) and first to receive up to 12 spacial LTE data streams simultaneously.
“It is the first commercially announced Gigabit LTE chipset designed to deliver fiber-like LTE Category 18 download speeds of up to 1.2 Gbps, a 20 percent improvement in download speeds over the previous generation. Additionally, it allows support for up to 5x20 MHz downlink Carrier Aggregation (CA) across licensed and unlicensed FDD and TDD radio frequencies, as well as 4x4 MIMO on up to three aggregated LTE carriers. Lastly, it supports integrated Dual SIM Dual VoLTE (DSDV) capability, a first for Snapdragon LTE modems. These leading-edge features of the Snapdragon X20 LTE modem are supported by the first commercially announced single-chip RF transceiver capable of simultaneously receiving up to 12 spatial streams of LTE data.”
Compared the the X16 modem featured in the upcoming Snapdragon 835 SoC, the Snapdragon X20 LTE modem moves from Cat 16 to Cat 18 on the downlink, with support for 5x20 MHz (vs. the X16’s 4x20 MHz) Carrier Aggregation and “can simultaneously receive 12 unique streams of data on as few as three 20 MHz carriers”, with up to 256-QAM and 100 Mbps per stream. Uplink is at the same 2x20 MHz/64-QAM as the X16 modem, for speeds of up to 150 Mbps.
The X20 LTE modem now includes VoLTE for both cards in a dual-SIM implementation:
“The Snapdragon X20 LTE modem also features more advanced dual SIM functionality and, as the first Snapdragon LTE modem to support DSDV, it provides users with the benefits of Ultra HD Voice and other IMS-based services on both SIMs inserted into the device.”
Qualcomm has begun to sample the Snapdragon X20 LTE modem to customers, with the first commercial devices expected 1H 2018.

When VR started to take off, developers begun to realize that audio is worth some attention. Historically, it’s been difficult to market, but that’s par for the course when it comes to VR technology, so I guess that’s no excuse to pass it up anymore. Now Valve, the owners of the leading VR platform on the PC have just released an API for audio processing: Steam Audio SDK.
Image Credit: Valve Software
First, I should mention that the SDK is not quite open. The GitHub page (and the source code ZIP in its releases tab) just contain the license (which is an EULA) and the readme. That said, Valve is under no obligation to provide these sorts of technology to the open (even though it would be nice) and they are maintaining builds for Windows, Mac, Linux, and Android. It is currently available as a C API and a plug-in for Unity. Unreal Engine 4, FMOD, and WWISE plug-ins are “coming soon”.
As for the technology itself, it has quite a few interesting features. As you might expect, it supports HRTF out of the box, which modifies a sound call to appear like it’s coming from a defined direction. The algorithm is based on experimental data, rather than some actual, physical process.
More interesting is their sound propagation and occlusion calculations. They are claiming that this can be raycast, and static scenes can bake some of the work ahead-of-time, which will reduce runtime overhead. Unlike VRWorks Audio or TrueAudio Next, it looks like they’re doing it on the CPU, though. I’m guessing this means that it will mostly raycast to fade between versions of the audio, rather than summing up contributions from thousands of individual rays at runtime (or an equivalent algorithm, like voxel leakage).
Still, this is available now as a C API and a Unity Plug-in, because Valve really likes Unity lately.

Tagged: mid tower, led, FSP Group, fsp, atx
Today FSP Group (a company mainly known for power supplies with headquarters in Taiwan) is launching a new mid tower ATX computer case called the CMT210. The new PC mid-tower features a transparent side window, black angular exterior with LED accents, and a focus on cooling performance. The 460mm x 220mm x 432mm steel case is aimed at gamers and enthusiasts that want to show off their PC internals.
The front of the CMT210 mid tower is dominated by a massive filtered vent that houses up to three 120mm fans or a 360mm water cooling radiator. The large vent with angled “water droplet” mesh is surrounded by a shroud that features colored accents in either black, red, silver, or deep blue depending on the model you choose. Up top the case offers two audio jacks, two USB 3.0 ports, and a single USB 2.0 port. (The USB 3.0 ports can be plugged into a USB 2.0 motherboard header with the included adapter if you are still holding off on upgrading to Kaby Lake or Ryzen.)
The top of the case is flat with no vents, and there are also no vents on the bottom. Instead there is a single 120mm exhaust fan vent at the rear of the case. FSP includes two of its own 120mm LED fans with the case that come pre-installed in the front and back.
The CMT210 is compatible with ATX motherboards, seven PCI slots, three 3.5” and three 2.5” tool-less drive bays, CPU coolers up to 160mm high and graphics cards up to 360mm long, and ATX power supplies (20.5cm). The power supply is bottom mounted in this case and the storage drives are snapped into trays in the bottom-front caddy and motherboard tray. There are cutouts for cable routing but no rubber grommets (not the end of the world, but they are a nice touch).
FSP claims that its new case is designed with "cooling, expansion, and compatibility" in mind. It is available now in the US though pricing is still unknown as retailers have not put up product pages yet. For more information on the CMT210 you can find details on this product page and this video.
I am curious how well the cooling setup will work with only a single exhaust fan especially if you had a multi GPU setup with aftermarket coolers. Hopefully Sebastian can put it through its paces at some point to examine the build quality and cooling prowess claims. If the price is right, it could be a good budget case as it does not look too bad and does not go crazy with LEDs and bling which is nice to see (I may just be getting old though haha).
What are your thoughts on PSU maker FSP Group getting into the case market?

The Azio Armato is a big aluminium keyboard, with five macro keys located on the lower left, on the upper right are media control buttons beside the large volume knob. The keyboard does come with a wrist rest, which attaches via a magnet so you can choose to remove it at will. The keyboard does not require software, lighting is controlled via keystrokes and macros are recorded by pushing that large REC button and one of the macro keys, then up to up to 31 keys in sequence and the REC button again to save the macro. You can see more of the Armato over at Benchmark Reviews.
"In any case Benchmark Reviews has in hand their Armato Mechanical Gaming Keyboard, model MGK-ARMATO-01. As a single-color backlit mechanical keyboard with Cherry MX switches, it might seem as if there’s little to distinguish it from the many other similar products available. But first appearances can be deceiving, as we’ll find out in this review."

Tagged: gaming, dawn of war III, wauughh
Dawn of War certainly changes from version to version. The first involved standard RTS fare, build bases and upgrade using resources collected on the map. The second was more squad based, with a hero leading meatshields into the fray. The third incarnation seems to lead off of the gameplay of the second, with at least some base and resource management making a comeback.
The new feature are superunits, extremely large and destructive units which you will gain access to as you take over portions of the map. Details are still a bit light but the game engine certainly looks pretty. You can pop by Rock, Paper, SHOTGUN to find a few of the other older teaser trailers.
"This cinematic-o-gameclip video introduces the broad story in Relic’s RTS and yes, it does basically boil down to finding a pointy stick. But what better item to fight over? If you can win a fight without a pointy stick, just imagine how powerful you’ll be once you get one!"

Tagged: MWC, GDC, VRMark, Servermark, OptoFidelity, cyan room, benchmark
Futuremark are showing off new benchmarks at GDC and MWC, the two conferences which are both happening this week. We will have quite a bit of coverage this week as we try to keep up with simultaneous news releases and presentations.
First up is a new benchmark in their recently released DX12 VRMark suite, the new Cyan Room which sits between the existing two in the suite. The Orange Room is to test if your system is capable of providing you with an acceptable VR experience or if your system falls somewhat short of the minimum requirements while the Blue Room is to show off what a system that exceeds the recommended specs can manage. The Cyan room will be for those who know that their system can handle most VR, and need to test their systems settings. If you don't have the test suite Humble Bundle has a great deal on this suite and several other tools, if you act quickly.
Next up is a new suite to test Google Daydream, Google Cardboard, and Samsung Gear VR performance and ability. There is more than just performance to test when you are using your phone to view VR content, such as avoiding setting your eyeholes on fire. The tests will help you determine just how long your device can run VR content before overheating becomes an issue and interferes with performance, as well as helping you determine your battery life.
VR Latency testing is the next in the list of announcements and is very important when it comes to VR as high or unstable latency is the reason some users need to add a bucket to their list of VR essentials. Futuremark have partnered with OptoFidelity to produce VR Multimeter HMD hardware based testing. This allows you, and hopefully soon PCPer as well, to test motion-to-photon latency, display persistence, and frame jitter as well as audio to video synchronization and motion-to-audio-latency all of which could lead to a bad time.
Last up is the brand new Servermark to test the performance you can expect out of virtual servers, media servers and other common tasks. The VDI test lets you determine if a virtual machine has been provisioned at a level commensurate to the assigned task, so you can adjust it as required. The Media Transcode portion lets you determine the maximum number of concurrent streams as well as the maximum quality of those streams which your server can handle, very nice for those hosting media for an audience.
Expect to hear more as we see the new benchmarks in action.
