Fremont, California — October 24, 2013 — Corsair, a worldwide designer of high-performance components for the PC hardware market, today announced the Hydro Series H75 dual-fan 120mm liquid CPU cooler. The easy-to-install H75 provides PC users with quieter and more effective cooling than stock CPU coolers, all in a 120mm footprint that is widely compatible with most PC cases on the market. The Hydro Series H75 will be available in November at a suggested retail price of $84.99 (USD).
The Hydro Series H75 is comprised of a low-profile CPU cooling block connected to a 120mm radiator and fan assembly via kink-resistant rubber tubing. The H75’s new cooling block is designed with a micro-fin copper cold plate and a high-quality, ceramic bearing pump that provides reliable, low-noise heat transfer away from the CPU. The slim 25mm thick radiator is surrounded by dual SP120L PWM 120mm fans resulting in design that is quieter and thinner than other dual fan coolers, and more effective at dispersing heat than single fan designs. The H75’s fans work with PWM motherboard fan headers, allowing users to control the fan speed and noise levels from their motherboard’s built-in software or BIOS.
“The H75 is a great choice for PC enthusiasts who want the streamlined features of our H60 120mm cooler but desire the additional cooling performance of a dual fan design,” said Xavier Lauwaert, Director of Product Marketing at Corsair.
The Hydro Series H75 features a simple, tool-free mounting system and wide Intel and AMD socket compatibility. Like all Hydro Series liquid CPU coolers, the H75 is completely self-contained and does not require filling or maintenance.

It was a simpler time of black screens and white text, perhaps green or orange depending on your flavour of monochrome, where ancient viruses roamed the world of 3.5" floppies and MS-DOS. These were not the viruses of today that do their best to sneak onto your machine and hide their shame from the user as best they could, these were created by people who wanted to show off their skills by letting you know something funny was going on. Wired talked with Daniel White who has amassed a huge amount of information on malware that covers decades of computer abuse, with a YouTube video for each and every one. While some may bring back horrible memories of your fights with old viral enemies the ones from the MS-DOS era which were mostly benign and very entertaining may bring a smile to some older geeks faces.
They did leave out one of my favourites, jump to 2:15 in the video below to see CASCADE.COM in action.
"But while the recent Windows worms may be the most familiar, another subset of White’s archive is even more interesting. The viruses he’s collected from the MS-DOS era are malware from a simpler time–a glimpse into a largely forgotten and surprisingly creative subculture."

Tagged: amd, firepro
Currently AMD holds 18% market share with their FirePro line of professional GPUs. This compares to NVIDIA who owns 81% with Quadro. I assume the "other" category is the sum of S3 and Matrox who, together, command 1% of the professional market (just the professional market)
According to Jon Peddie of JPR, as reported by X-Bit Labs, AMD intends to wrestle back revenue left unguarded for NVIDIA. "After years of neglect, AMD’s workstation group, under the tutorage of Matt Skyner, has the backing and commitment of top management and AMD intends to push into the market aggressively." They have already gained share this year.
During AMD's 3rd Quarter (2013) earnings call, CEO Rory Read outlined the importance of the professional graphics market.
We also continue to make steady progress in another of growth businesses in the third quarter as we delivered our fifth consecutive quarter of revenue and share growth in the professional graphics area. We believe that we can continue to gain share in this lucrative part of the GPU market based on our product portfolio, design wins in flight, and enhanced channel programs.
On the same conference call (actually before and after the professional graphics sound bite), Rory noted their renewed push into the server and embedded SoC markets with 64-bit x86 and 64-bit ARM processors. They will be the only company manufacturing both x86 and ARM solutions which should be an interesting proposition for an enterprise in need of both. Why deal with two vendors?
Either way, AMD will probably be refocusing on the professional and enterprise markets for the near future. For the rest of us, this hopefully means that AMD has a stable (and confident) roadmap in the processor and gaming markets. If that is the case, a profitable Q3 is definitely a good start.

Fremont, CA (October 22nd, 2013) - ASUS today announced the Xonar Essence STU USB external digital-to-analog converter (DAC) and headphone amplifier, based on the acclaimed design and quality of Xonar Essence ST/STX internal sound cards and going beyond their already high standards. Offering audiophile-grade performance, Xonar Essence STU delivers USB connectivity and accessible external controls.
It offers clear sound with a 120dB signal to noise ratio (SNR), strong 600ohm headphone amplifier, asynchronous USB audio and swappable Op-Amps for DIY sound modification. Precision clock tuning technology further enhances audio fidelity, making Xonar Essence STU a great choice for discerning music lovers who need a quality DAC and headphone amplifier to drive the full capabilities of high-end headphones.
"We received considerable positive feedback from customers regarding the excellent sound quality of Xonar Essence ST/STX sound cards, which led us to develop Xonar Essence STU as a USB device that offers even more premium audio quality plus easy controls and connectivity to notebooks. This is another example of ASUS listening to the community and acting on consumer demand”, said Ives Chiu, Audiovisual Product Manager at the ASUS Multimedia Business Unit.
High quality precision audio
Xonar Essence STU delivers clean, clear, and low distortion sound with 120dB SNR. It achieves this thanks to exacting hardware design, which includes balanced (or mirrored) PCB layout for accurate reproduction of all sound sources and minimal component crosstalk, or interference.
ASUS uses audio industry-leading components such as the Texas Instruments PCM1792A DAC and TPA6120A2 headphone amplifier, which supports up to 600ohm impedance. Also included are audiophile-approved WIMA FKP2 and Nichicon Finegold capacitors for balanced and rich sound.
To satisfy the most demanding users, Xonar Essence STU features precision clock tuning technology and asynchronous audio transfer. Both ensure accurate and jitter-free sound fidelity, allowing customers to enjoy music in its purest form. Bit-perfect playback is aided by support for ASIO audio drivers.
Complete ease of use
As an external device, Xonar Essence STU offers readily-accessible controls with no need to go into software menus. Customers can switch between low and high gain settings, accommodating better listening experiences across a wide range of headphones, from in-ear headsets (typically 16ohm-32ohm) to premium full-size headphones (up to 600ohm). This is especially useful with the increasing popularity of mobile devices, which normally ship with low impedance/high sensitivity headsets.
Dual volume controls help users change speaker and headphone sound levels simultaneously, similar to features offered by dedicated audio decks. The USB interface means connectivity with USB-compliant devices, while I/O ports include stereo RCA out, a 6.3mm headphone jack, two digital inputs, and auxiliary in.
Xonar Essence STU can be placed horizontally and vertically with a bundled stand, giving customers more space-saving flexibility for different locations and situations.
Tonal tuning and advanced controls
Texas Instruments NS-LME49720 and NS-LM4562NA Op-Amps (or operational amplifiers) deliver acoustics fine-tuned by audio engineers to support livelier and more detailed spacious sound.
Xonar Essence STU has room for three swappable Op-Amps, which can be replaced by users to adjust tonal performance based on personal taste. This open-ended and customizable design is inherited from previous Xonar Essence audio products, and remains true to the series’ commitment to accommodating as many customer preferences as possible.
Additional advanced features are a jumper switch that re-routes sound via Xonar Essence STU, allowing it to be used as a pre-amplifier in conjunction with a dedicated power amplifier. Customers can opt to adjust master volume directly on the power amplifier without having to reach Xonar Essence STU controls. Also, a selectable DC servo headphone output can be activated to minimize pop noise which may occur when powering on.
AVAILABILITY & PRICING
The ASUS Xonar Essence STU will be available from late October worldwide with an MSRP of US$399.

Having already seen what the ASUS R9 280X DirectCU II TOP can do at default speeds the obvious next step, once they had time to fully explore the options, was for [H]ard|OCP to see just how far this GPU can overclock. To make a long story short, they went from a default clock of 1070MHz up to 1230MHz and pushed the RAM to 6.6GHz from 6.4GHz though the voltage needed to be bumped from 1.2v to 1.3v. The actual frequencies are nowhere near as important as the effect on gameplay though, to see those results you will have to click through to the full article.
"We take the new ASUS R9 280X DirectCU II TOP video card and find out how high it will overclock with GPU Tweak and voltage modification. We will compare performance to an overclocked GeForce GTX 770 and find out which card comes out on top when pushed to its overclocking limits."

Seagate's aptly named NAS HDD looks very much like their 4TB Desktop model but internally it has enhanced vibration reduction as well as parts that are more resistant to vibration which should create a quieter and longer lasting drive. It also shares 5900 RPM and a 64MB cache but Seagate claims slightly higher seek times, 8.5ms read and 9.5ms write and time-limited error recovery which makes these drives far less dangerous to use in a RAID than the desktop model in scenarios such as Al has mentioned numerous times. The Tech Report's testing put it against Seagate's Desktop version as well as the WD Red that is also optimized for use in NAS devices, read on to see which gets recommended.
"Seagate's NAS HDD 4TB is optimized for network-attached storage and desktop RAID implementations. It promises better reliability than typical desktop drives, too. We take a closer look to see how the NAS HDD compares to its WD Red counterpart."

Once again EA has decided to include a single player campaign for the new Battlefield and it will hopefully be better than previous attempts that tended to be as gripping as 3 year old scotch tape. You can catch the trailer below if you are feeling the need to see cutscenes full of screaming and explosions and if you are interested in commentary you can pick some up at Rock, Paper, SHOTGUN. As most of the people who played the campaign of BF3 they are only familiar with the first few minutes that it takes to run a benchmark the quality of story in the single player campaign matter very little; most are more hopeful the bugs which plagued Bad Company and BF3's multiplayer will be nonexistent in the newest incarnation.
"So now I want to know: who plays the single-player bits of Battlefield games, and were you/are you excited about the fourth game’s offline shootery? Actually, you should probably wait until watching the trailer before answering that, because it looks a bit crap."

Tagged: amd, hUMA
hUMA's currently well know trick, a shared memory space which both the CPU and GPU can access without penalty is only the first of its revealed optimizations. The Register talks today about another way in which this new architecture allows the CPU and GPU equal treatment, standardized task queues and dispatch packets which avoid dealing with a kernel level driver to assign tasks. With hUMA the GPU is able to shedule tasks for the CPU directly. That would allow any application that was designed to hUMA standards to have its various tasks assigned to the proper processor without needing extra coding. This not only makes it cheaper and quicker to design apps but would allow all hUMA apps to take advantage of the specialized abilities of both the CPU and GPU at no cost.
"The upcoming chips will utilise a technique AMD calls Heterogeneous Queuing (hQ). This new approach puts the GPU on an equal footing with the CPU: no longer will the graphics engine have to wait for the central processor to tell it what to do."

Mid-June kicked up a storm of poop across the internet when IGN broke the AMD optimizations for Frostbite 3. It was reported that NVIDIA would not receive sample code for those games until after they launched. The article was later updated with a statement from AMD: "... the AMD Gaming Evolved program undertakes no efforts to prevent our competition from optimizing for games before their release."
Now, I assume, the confusion was caused by then-not-announced Mantle.
And, as it turns out, NVIDIA did receive the code for Battlefield 4 prior to launch. Monday, the company launched their 331.58 WHQL-certified drivers which are optimized for Batman: Arkham Origins and Battlefield 4. According to the release notes, you should even be able to use SLi out of the gate. If, on the other hand, you are a Civilization V player: HBAO+ should enhance your shadowing.
They also added a DX11 SLi profile for Watch Dogs... awkwarrrrrd.
To check out the blog at GeForce.com for a bit more information, check out the release notes, or just head over to the drivers page. If you have GeForce Experience installed, it probably already asked you to update.

Seasonic (Sea Sonic Electronics) has announced a design win that will see its power supplies used in HashFast’s bitcoin mining rigs. The upcoming HashFast mining rigs feature the company’s “Golden Nonce” ASIC(s) and all-in-one water coolers. HashFast has a single ASIC Baby Jet and multi-ASIC Sierra rig. Both units will be available December 15 starting at $2,250 and $6,300 respectively.
The Seasonic power supplies are high efficiency models with Japanese capacitors and at least 80 PLUS Bronze. On the high end, Seasonic has PSUs that are up to 93% efficient. HashFast stated that it chose Seasonic for its mining rigs because of the build quality and efficiency. The Baby Jet and Sierra mining rigs allow users to overclock the ASICs, and the systems can be rather demanding on PSUs.
The Golden Nonce ASIC is a 28nm chip that is rated at 400 GHash/s and 0.65 Watts per Gigahash.
Beyond that, the companies have not gone into specifics. It is good news for Seasonic, and should mean a stable system for bitcoin miners (the 93% efficiency rating is nice as well, as it means less wasted electricity and slightly more bitcoin mining profit).
The full press blast is below for reference.

We all spend a lot of time sitting at a PC, perhaps far more than we should from a health standpoint. The biggest casualty of our lifestyle is our spine and the backbone is connected to ... all bones; either directly or through the nervous system. Since we are unlikely to follow the health instructions on the bottom of our keyboard and not all of us are willing to sit on a yoga ball all day, regardless of its efficacy a new chair is often a life changer. Herman Miller is a popular brand although as those chairs tend to be worth their weight in gold it is nice to know there are some alternatives out there. The Tech Report has just put up an article covering the Steelcase Leap, a chair almost as expensive as a Herman Miller but perhaps even more effective at reducing back strain. Even if you haven't yet felt the twinges of a developing back problem it might be worth checking this review and thinking about an upgrade for your back.
I personally have spondylolisthesis and would not wish it on my worst enemy.
"This week, TR's Cyril Kowaliski blogs about the Steelcase Leap, a fancy task chair he got to replace his Herman Miller Mirra after developing some upper-back problems."

During their annual event today at the Yerba Buena Center for the Arts in San Francisco, Apple announced updates to their Mac lineups. After updating the MacBook Air with Haswell processors and teasing the new Mac Pro in June during WWDC, the rest of their offerings have seemed a little outdated.
Today, Apple started with a recap of the upgrades they have included in the next OS X release, Mavericks. Things like improved multi monitor support, and even more technical features like OpenCL support for integrated graphics and RAM compression were all talked about.
Perhaps the biggest news about OS X Mavericks is that it will be a free release to all users on 10.6 (Snow Leopard), 10.7 (Lion), or 10.8 (Mountain Lion), as long as their hardware is compatible. Mavericks is available today through the Mac App store.

UPDATE: If you missed our live stream today that covered NVIDIA G-Sync technology, you can watch the replay embedded below. NVIDIA's Tom Petersen stops by to talk about G-Sync in both high level and granular detail while showing off some demonstrations of why G-Sync is so important. Enjoy!!
Last week NVIDIA hosted press and developers in Montreal to discuss a couple of new technologies, the most impressive of which was NVIDIA G-Sync, a new monitor solution that looks to solve the eternal debate of smoothness against latency. If you haven't read about G-Sync and how impressive it was when first tested on Friday, you should check out my initial write up, NVIDIA G-Sync: Death of the Refresh Rate, that not only does that, but dives into the reason the technology shift was necessary in the first place.
G-Sync essentially functions by altering and controlling the vBlank signal sent to the monitor. In a normal configuration, vBlank is a combination of the combination of the vertical front and back porch and the necessary sync time. That timing is set a fixed stepping that determines the effective refresh rate of the monitor; 60 Hz, 120 Hz, etc. What NVIDIA will now do in the driver and firmware is lengthen or shorten the vBlank signal as desired and will send it when one of two criteria is met.
- A new frame has completed rendering and has been copied to the front buffer. Sending vBlank at this time will tell the screen grab data from the card and display it immediately.
- A substantial amount of time has passed and the currently displayed image needs to be refreshed to avoid brightness variation.
In current display timing setups, the submission of the vBlank signal has been completely independent from the rendering pipeline. The result was varying frame latency and either horizontal tearing or fixed refresh frame rates. With NVIDIA G-Sync creating an intelligent connection between rendering and frame updating, the display of PC games is fundamentally changed.
Every person that saw the technology, including other media members and even developers like John Carmack, Johan Andersson and Tim Sweeney, came away knowing that this was the future of PC gaming. (If you didn't see the panel that featured those three developers on stage, you are missing out.)
But it is definitely a complicated technology and I have already seen a lot of confusion about it in our comment threads on PC Perspective. To help the community get a better grasp and to offer them an opportunity to ask some questions, NVIDIA's Tom Petersen is stopping by our offices on Monday afternoon where he will run through some demonstrations and take questions from the live streaming audience.
Be sure to stop back at PC Perspective on Monday, October 21st at 2pm ET / 11am PT as to discuss G-Sync, how it was developed and the various ramifications the technology will have in PC gaming. You'll find it all on our PC Perspective Live! page on Monday but you can sign up for our "live stream mailing list" as well to get notified in advance!
NVIDIA G-Sync Live Stream
11am PT / 2pm ET - October 21st
We also want your questions!! The easiest way to get them answered is to leave them for us here in the comments of this post. That will give us time to filter through the questions and get the answers you need from Tom. We'll take questions via the live chat and via Twitter (follow me @ryanshrout) during the event but often time there is a lot of noise to deal with.
So be sure to join us on Monday afternoon!

As the picture below makes clear, the Corsair RM750 is a fully modular PSU which lets you pick and choose exactly what cables you want present in your system. The single 12v rail is rated at 62.5A which should handle two fairly powerful GPUs, there are four 6+2 PCIe power connectors to do so. This unit is rated 80 Plus Gold and it did live up to that rating in [H]ard|OCP's testing. Unfortunately the efficiency and silent operation were the only things [H] was impressed by as this unit really struggled in their testing and even those tests where it could manage a passing grade the PSU lagged behind the competition.
"We have all read about Corsair power supplies and it is quite likely that many [H]'ers have one in their computer case right now. Today we are looking at Corsair's newest RM series power supply rated at 750 watts. The RM is built, "fully modular and optimized for silence and high efficiency." Let's see how it handles our grueling power tests."

Imagination Technologies, a company known for its PowerVR graphics IP, has unleashed its first Warrior P-series MIPS CPU core. The new MIPS core is called the P5600 and is a 32-bit core based on the MIPS Release 5 ISA (Instruction Set Architecture).
The P5600 CPU core can perform 128-bit SIMD computations, provide hardware accelerated virtualization, and access up to a 1TB of memory via virtual addressing. While the MIPS 5 ISA provides for 64-bit calculations, the P5600 core is 32-bit only and does not include the extra 64-bit portions of the ISA.
The MIPS P5600 core can scale up to 2GHz in clockspeed when used in chips built on TSMC's 28nm HPM manufacturing process (according to Imagination Technologies). Further, the Warrior P5600 core can be used in processors and SoCs. As many as six CPU cores can be combined and managed by a coherence manager and given access to up to 8MB of shared L2 cache. Imagination Technologies is aiming processors containing the P5600 cores at mobile devices, networking appliances (routers, hardware firewalls, switches, et al), and micro-servers.
A configuration of multiple P5600 cores with L2 cache.
I first saw a story on the P5600 over at the Tech Report, and found it interesting that Imagination Technologies was developing a MIPS processor aimed at mobile devices. It does make sense to see a MIPS CPU from the company as it owns the MIPS intellectual property. Also, a CPU core is a logical step for a company with a large graphics IP and GPU portfolio. Developing its own MIPS CPU core would allow it to put together an SoC with its own CPU and GPU components. With that said, I found it interesting that the P5600 CPU core was being aimed at the mobile space, where ARM processors currently dominate. ARM is working to increase performance while Intel is working to bring its powerhouse x86 architecture to the ultra low power mobile space. Needless to say, it is a highly competitive market and Imagination Technologies new CPU core is sure to have a difficult time establishing itself in that space of consumer smartphone and tablet SoCs. Fortunately, mobile chips are not the only processors Imagination Technologies is aiming the P5600 at. It is also offering up the MIPS Series 5 compatible core for use in processors powering networking equipment and very low power servers and business appliances where the MIPS architecture is more commonplace.
In any event, I'm interested to see what else IT has in store for its MIPS IP and where the Warrior series goes from here!
