Is it Bait and Switch or not?

There is a wee bit of outrage in the community over the internals of Kingston's SSDNow V300 and PNY's Optima SSDs.  In both cases the internals being sold at the moment do not match the internals that were originally benchmarked and people are outraged that the same product with a different model number has changed internals.  The two drives are marketed towards value conscious purchasers and represent two different cases of modifications; Kingston with a flash change and PNY with a controller change.

The complaints against PNY are a little odd, it would seem that the 4-channel SMI 2246en controller was swapped for an 8-channel LSI SandForce SF-2281 with no price change and the only way you can be upset by that is because of a ridiculous level of brand loyalty.  On the other hand Kingston has switched from Synchronous to Asynchronous NAND flash memory which does have a noticeable impact on performance and the stamina of the flash and also happens to be less expensive to manufacture.  If Kingston had left the price as it was originally and specified the use of Synchronous Flash in the V300 series then you would have a good argument that they had intentionally mislead customers.  The reality is that the type of flash was not specified and the price of a 120GB SSDNow V300 has halved since its release which makes this more of a slightly shady product refresh.  It is not the best way to update your product line but considering the specifics of this particular case it really does not show intent to deceive.

If you really want something to be upset about then consider the example provided by The SSD Review; ASUS's swapping out of the SSD in their ZenBook with utterly no warning or price change.  Now that is Bait and Switch!

"It seems that the world of technology has stopped with allegations that some SSD companies are pulling the old ‘bait and switch’ routine in their SSDs by switching off components that many had recognized through initial SSD reviews. We have read several reports and forums, most of which simply repeat the original information, and finally have decided to clarify things just a bit from our perspective. Get ready though as many may not like our viewpoint; it goes against the grain somewhat."

Why would SanDisk buy Fusion-io for $1.1 Billion?

Subject: Editorial, Storage | June 17, 2014 - 09:56 AM |
Tagged: sandisk, fusion-io, buyout

Fusion-io was once a behemoth of flash memory storage. Back when SSDs were having a hard time saturating SATA 3Gb/sec, Fusion-io was making fire breathing PCIe SSDs full of SLC flash and pushing relatively insane IOPS and throughput figures. Their innovations were a good formula at the time. They made the controller a very simple device, basically just a simple bridge from the PCIe bus to the flash memory. This meant that most of the actual work was done in the driver. This meant that Fusion-io SSDs were able to leverage the CPU and memory of the host system to achieve very high performance.

iops (2010).jpg

Fusion-io ioDrive 160 creams the competition back in 2010.

Being the king of IOPS back in the early days of flash memory storage, Fusion-io was able to charge a premium for their products. In a 2010 review, I priced their 160GB SSD at about $40/GB. In the years since, while flash memory prices (and therefore SSD products) have steadily dropped in price while achieving higher and higher performance figures, Fusion-io products have mostly remained static in price. All of this time, the various iterations of the ioDrive continued to bank on the original model of a simple controller and the bulk of the work taking place in the driver. This actually carries a few distinct disadvantages, in that the host system has to spent a relatively large amount of CPU and memory resources towards handling the Fusion-io devices. While this enables higher performance, it leaves less resources available to actually do stuff with the data. This ends up adding to the build cost of a system, as more CPU cores and memory must be thrown at the chassis handling the storage. In more demanding cases, additional systems would need to be added to the rack space in order to handle the additional storage overhead in addition to the other required workloads. Lastly, the hefty driver means Fusion-io devices are not bootable, despite early promises to the contrary. This isn't necessarily a deal breaker for enterprise use, but it does require system builders to add an additional storage device (from a different vendor) to handle OS duties.

iops (2014).png

In 2014, the other guys are making faster stuff. Note this chart is 4x the scale of the 2010 chart.

Lets fast forward to present times. Just over a week ago, Fusion-io announced their new 'Atomic' line of SSDs. The announcement seemed to fall flat, and did little to save the continuous decline of their stock price. I suspect this was because despite new leadership, these new products are just another iteration of the same resource consuming formula. Another reason for the luke warm reception might have been the fact that Intel launched their P3700 series a few days prior. The P3700 is a native PCIe SSD that employs the new NVM Express communication standard. This open standard was developed specifically for flash memory communication, and it allows more direct access to flash in a manner that significantly reduces the overhead required to perform high data throughputs and very high IO's per second. NVMe is a very small driver stack with native support built into modern operating systems, and is basically the polar opposite of the model Fusion-io has relied on for years now.

Intel's use of NVMe enables very efficient access to flash memory with minimal CPU overhead.

Fusion-io's announcement claimed "The Atomic Series of ioMemory delivers the highest transaction rate per gigabyte for everything from read intensive workflows to mixed workloads.". Let's see how this stacks up against the Intel P3700 - an SSD that launched the same week:

We are comparing flagship to flagship (in a given form factor) here. Starting from the top, the Intel P3700 is available in generally smaller capacities than the Fusion-io PX600. Both use 20nm flash, but the P3700 uses half the data lanes at twice the throughput. Regarding Fusion-io's 'transaction rate per GB' point, well, it's mostly debunked by the Intel P3700, which has excellent random read performance all the way down to its smallest 400GB capacity point. The seemingly unreal write specs seen from the PX600 are, well, actually unreal. Flash memory writes take longer than reads, so the only logical explanation for the inversion we see here is that Fusion-io's driver is passing those random writes through RAM first. Writing to RAM might be quicker, but you can't sustain it indefinitely, and it consumes more host system resources in the process. Moving further down the chart, we see Intel coming in with a ~50% higher endurance rating when compared to the Fusion-io. The warranties may be of equal duration, but the Intel drive is (on paper / stated warranty) guaranteed to outlast the Fusion-io part when used in a heavy write environment.

For pricing, Intel launched the P3700 at a competitive $3/GB. Pricing data for Fusion-io is not available, as they are behind a bit of a 'quote wall', and no pricing at all was included with the Atomic product launch press materials. Let's take a conservative guess and assume the new line is half the cost/GB of their previous long-standing flagship, the Octal. One vendor lists pricing directly at $124,995 for 10.24TB ($12.21/GB) and $99,995 for 5.12TB ($19.53/GB), both of which require minumum support contracts as an additional cost. Half of $12/GB is still more than twice the $3/GB figure from Intel.

My theory as to why SanDisk is going for Fusion-io?

  • A poor track record since the Fusion-io IPO have driven the stock price way down, making it prime for a buyout.
  • SanDisk is one of the few remaining flash memory companies that does not own their own high end controller tech.
  • Recent Fusion-io product launch overshadowed by much larger (Intel) company launching a competing superior product at a lower cost/GB.

So yeah, the buyout seemed inevitable. The question that remains is what will SanDisk do with them once they've bought them? Merging the two will mean that Fusion-io can include 'in house' flash and (hopefully) offer their products at a lower cost/GB, but that can only succeed if the SanDisk flash performs adequately. Assuming it does, there's still the issue of relatively high costs when compared to freshly competing products from Intel and others. Last but not least is the ioDrive driver model, which grows incresingly dated while the rest of the industry adopts NVMe.

Tech Report's SSD Endurance: The Petabyte Club

In The Tech Report's ongoing SSD endurance challenge, three SSDs are soldiering forward. We have reached the thousand-terabyte mark, which is at least five times more than any of the survivors are rated for. These survivors: The Corsair Neutron GTX, the Samsung 840 Pro, and the Kingston HyperX 3K. Technically, the HyperX was able to reach 1PB of written data with performing only 716TB of actual writes, due to compression.

Of course, each of the drives are less-than prestine. The Corsair Neutron GTX 240GB was slowly decreasing in its "life" attribute since the beginning, claiming to be somewhere between 75% and 80% with a fairly linear decline. If this trend continues, the drive will reach "zero" at around 4-5PB of writes. That said, its read speed has substantially dropped from the time between 900TB and 1000TB of total writes, from 500MB/s to just under 400MB/s. Also, this "life" could drop substantially if the drive encounters reallocated sectors (which this model has apparently yet to do).

The other two drives are a similar, remarkably successful story.

The Kingston HyperX drive is reporting itself to be substantially worse off, within the last 10% of its life. That said, even though it claims to be pining for the fjords, it is still working and has only reported a couple of reallocated sectors, those occurring in the last 100TB of writes.

The Samsung 840 Pro seems to still be going strong, although it had more zero or "a couple" of reallocated sectors -- every hundred terabytes yields about 500 reallocations.

As always, this is just our brief discussion of what The Tech Report found out. Be sure to check out their full article for many more benchmarks, tests, and conclusions.

Kids these days get all the cool toys, not just G.I. Joe's with missiles that actually fire and portable gaming devices capable of more colours than light and dark green.  Mission Street Manufacturing's Printeer is a way to get kids interested in 3D printing and creating their own masterpieces, though at an estimated $550 it will likely be limited to schools and clubs as opposed to having their own printer.  The interface is a drawing program on an iPad, something that will be quite familiar to most children but now they will have the opportunity to print out their creations.  The printer is transparent as you can see from the picture at Engadget which allows these young makers to watch their creation made right in front of their eyes, a great way to get them excited about making things and a lot more fun than ShrinkyDinks!

"If Mission Street Manufacturing's Printeer hits its crowdfunding goal, though, children will have a 3D printer they can truly call their own.

ADATA Announces CFast 2.0 "Industrial Memory Cards"

Subject: General Tech, Storage, Mobile | June 16, 2014 - 01:54 AM |
Tagged:

CFast is a standard, based on the merging of CompactFlash with SATA, for memory cards to have SSD-like performance. It has been around for a while, CFast 2.0 having been released in Q4 2012, but with very limited adoption. You could count the number of camera models which use it on a single hand. Still, ADATA is entering that market with a lineup of memory cards, with quite a bit of variety.

adata-logo.jpg

The ADATA ISC3E will come in SLC (one stored bit per memory cell) and MLC (two stored bits per memory cell) models. Capacities will range from 4GB to 64GB (SLC) or 4GB to 128GB (MLC). Speeds are fairly low, compared to modern SSDs. SLC is rated at 165 MB/s read and 170 MB/s write, while MLC can read at 435 MB/s and write at 120 MB/s. They support ECC and S.M.A.R.T.

Of course, this is kind-of interesting in terms of its small, removable form factor. Beyond that, it seems to be a few years back in terms of SSD technology. For the high resolution (or high frame rate) camera use case, read and write speeds really do not matter, except when you transfer your media off of your device (which the MLC version is clearly better suited for). Otherwise, as long as your write speed is consistently above what the camera can output, going bigger will be wasted overhead. ADATA suggests using these CFast 2.0 cards in POS terminals and kiosks but, at that point, would you really need small and removable memory?

ADATA has not released pricing and availability.

Steam Deals: Splinter Cell Blacklist Is ~$10, Thief Is ~$15

Update: Uh, apparently GOG's DRM-Free Summer Sale (note: everything on GOG is DRM-Free) has not yet ended. Those deals are definitely worth your time to check out.

While I missed writing about GOG's Summer Sale (okay, at the time of this publishing, theres a few hours left), I can at least alert our readers about these two deals. Splinter Cell: Blacklist, released late last summer, is almost two-thirds off at $10.19 USD (normally $29.99). Also on sale is Thief, released in late February, for about half price at $14.99 USD (normally $29.99). If you purchased these games and wanted a little more content to them, each title's downloadable content is on sale for an equivalent markdown.

While not as unforgiving as Splinter Cell: Conviction, a UPLAY account is required to activate Blacklist. You do not, however, need to be continuously logged in to it in order to play its single player mode. I believe that Thief, on the other hand, just uses Steam for its DRM.

E3 2014: SteamBoy Project Is Not a Valve Product

Subject: General Tech, Mobile, Shows and Expos | June 15, 2014 - 01:51 AM |
Tagged: x86, SteamOS, Steam Machine, Steam Controller, steam, mobile, handheld, E3 14, E3

To be doubly clear, if the title was not explicit enough, this announcement is not made by Valve. This company is called, "SteamBoy Machine team". If not a hoax, this is one of the many Steam Machines which are expected to come out of the SteamOS initiative. Rather than taking the platform to a desktop or home theater PC (HTPC) form-factor, this company wants to target the handheld PC gaming market.

If it comes out, that is a clever use of SteamOS. I can see Big Picture Mode being just as useful on a small screen as it is on a TV, especially with its large font and controller navigation. The teasers suggest that it will use the haptic feedback-based touchpads which Valve are expected to base the Steam Controller on. It will also include a 5-inch touchscreen.

The Escapist got into contact with the team and received a few more specs:

  • Quad-Core CPU (x86)
  • 4GB RAM
  • 32GB built-in storage

Even if this company does not make good on their expectations, companies will now be considering portable SteamOS devices. This is the sort of outside-the-box thinking that Valve was pushing for when they wanted to create an open platform. Each party will struggle to win in their personal goals, yet they can also rely on the crowd (other companies or individuals) to keep up in areas where they do not want an edge.

Philosophy aside, the company is targeting 2015 with a "Standard Edition" supporting WiFi and 3G. It would make sense to have a WiFi-only model, but who knows.

BitFenix Aegis, Atlas, and Pandora Enclosures Shown Off at Computex 2014

Yes, Computex is over - and in its wake we’re still left with a ton of new product announcements. Three of these come from BitFenix, who unveiled new enclosures at their booth in Taipei last week.

 

atlas_01.jpg

 

The first is the BitFenix Atlas, which has incorporated some interesting design features including what they are calling “swappable chambers” and a “test-mode motherboard tray”. (Could this be an open test-bench feature?)

 

atlas_02.jpg

 

The design is very interesting (a bit along the lines of the Corsair Carbide Air 540), and the extra width allows for no less than ten 3.5” hard drive bays behind the motherboard tray! The Atlas also has six 2.5” bays for SSDs, and features a full array of dust filters and nifty RGB lighting.

 

Next we’ll look at the Aegis, a sleek minitower enclosure.

 

aegis.JPG

 

The Aegis supports micro-ATX and mini-ITX motherboards and features water cooling support and a built in fan controller. In addition to 240/280mm radiator support on the top, the Aegis also boasts 360mm radiator support up front.

 

Finally we have the Pandora, which in addition to streaming music (as I’ve been informed) is also apparently a PC case that looks like part of a stormtrooper’s armor.

 

pandora.JPG

 

Besides protecting imperial troops from rebel attacks, the Pandora offers a stylish take on a mini-ITX tower design and offers support for full-size ATX power supplies and (presumably) liquid cooling via two pairs of 120mm fan mounts.

 

No specifics on pricing or availability from BitFenix on these three new enclosures just yet, but expect them this year as they are part of the 2014 BitFenix catalog.

AMD Restructures. Lisa Su Is Now COO.

Tagged: x86, restructure, gpu, arm, APU, amd

According to VR-Zone, AMD has reworked their business, last Thursday, sorting each of their projects into two divisions and moving some executives around. The company is now segmented into the "Enterprise, Embedded, and Semi-Custom Business Group", and the "Computing and Graphics Business Group". The company used to be divided between "Computing Solutions", which handled CPUs, APUs, chipsets, and so forth, "Graphics and Visual Solutions", which is best known for GPUs but also contains console royalties, and "All Other", which was... everything else.

amd-new2.png

Lisa Su, former general manger of global business, has moved up to Chief Operating Officer (COO), along with other changes.

This restructure makes sense for a couple of reasons. First, it pairs some unprofitable ventures with other, highly profitable ones. AMD's graphics division has been steadily adding profitability to the company while its CPU division has been mostly losing money. Secondly, "All Other" is about a nebulous as a name can get. Instead of having three unbalanced divisions, one of which makes no sense to someone glancing at AMD's quarterly earnings reports, they should now have two, roughly equal segments.

At the very least, it should look better to an uninformed investor. Someone who does not know the company might look at the sheet and assume that, if AMD divested from everything except graphics, that the company would be profitable. If, you know, they did not know that console contracts came into their graphics division because their compute division had x86 APUs, and so forth. This setup is now more aligned to customers, not products.

GeForce GTX Titan Z Overclocking Testing

Subject: Graphics Cards | June 12, 2014 - 06:17 PM |
Tagged: overclocking, nvidia, gtx titan z, geforce

Earlier this week I posted a review of the NVIDIA GeForce GTX Titan Z graphics card, a dual-GPU Kepler GK110 part that currently sells for $3000. If you missed that article you should read it first and catch up but the basic summary was that, for PC gamers, it's slower and twice the price of AMD's Radeon R9 295X2.

During that article though I mentioned that the Titan Z had more variable clock speeds than any other GeForce card I had tested. At the time I didn't go any further than that since the performance of the card already pointed out the deficit it had going up against the R9 295X2. However, several readers asked me to dive into overclocking with the Titan Z and with that came the need to show clock speed changes. 

My overclocking was done through EVGA's PrecisionX software and we measured clock speeds with GPU-Z. The first step in overclocking an NVIDIA GPU is to simply move up the Power Target sliders and see what happens. This tells the card that it is allowed to consume more power than it would normally be allowed to, and then thanks to GPU Boost technology, the clock speed should scale up naturally. 

titanzoc.jpg

Click to Enlarge

And that is exactly what happened. I ran through 30 minutes of looped testing with Metro: Last Light at stock settings, with the Power Target at 112%, with the Power Target at 120% (the maximum setting) and then again with the Power Target at 120% and the GPU clock offset set to +75 MHz. 

That 75 MHz offset was the highest setting we could get to run stable on the Titan Z, which brings the Base clock up to 781 MHz and the Boost clock to 951 MHz. Though, as you'll see in our frequency graphs below the card was still reaching well above that.

clockspeedtitanz.png

Click to Enlarge

This graph shows clock rates of the GK110 GPUs on the Titan Z over the course of 25 minutes of looped Metro: Last Light gaming. The green line is the stock performance of the card without any changes to the power settings or clock speeds. While it starts out well enough, hitting clock rates of around 1000 MHz, it quickly dives and by 300 seconds of gaming we are often going at or under the 800 MHz mark. That pattern is consistent throughout the entire tested time and we have an average clock speed of 894 MHz.

Next up is the blue line, generated by simply moving the power target from 100% to 112%, giving the GPUs a little more thermal headroom to play with. The results are impressive, with a much more consistent clock speed. The yellow line, for the power target at 120%, is even better with a tighter band of clock rates and with a higher average clock. 

Finally, the red line represents the 120% power target with a +75 MHz offset in PrecisionX. There we see a clock speed consistency matching the yellow line but offset up a bit, as we have been taught to expect with NVIDIA's recent GPUs. 

clockspeedtitan-avg.png

Click to Enlarge

The result of all this data comes together in the bar graph here that lists the average clock rates over the entire 25 minute test runs. At stock settings, the Titan Z was able to hit 894 MHz, just over the "typical" boost clock advertised by NVIDIA of 876 MHz. That's good news for NVIDIA! Even though there is a lot more clock speed variance than I would like to see with the Titan Z, the clock speeds are within the expectations set by NVIDIA out the gate.

Bumping up that power target though will help out gamers that do invest in the Titan Z quite a bit. Just going to 112% results in an average clock speed of 993 MHz, a 100 MHz jump worth about 11% overall. When we push that power target up even further, and overclock the frequency offset a bit, we actually get an average clock rate of 1074 MHz, 20% faster than the stock settings. This does mean that our Titan Z is pulling more power and generating more noise (quite a bit more actually) with fan speeds going from around 2000 to 2700 RPM.

At both 2560x1440 and 3840x2160, in the Metro: Last Light benchmark we ran, the added performance of the Titan Z does put it at the same level of the Radeon R9 295X2. Of course, it goes without saying that we could also overclock the 295X2 a bit further to improve ITS performance, but this is an exercise in education.

Does it change my stance or recommendation for the Titan Z? Not really; I still think it is overpriced compared to the performance you get from AMD's offerings and from NVIDIA's own lower priced GTX cards. However, it does lead me to believe that the Titan Z could have been fixed and could have offered at least performance on par with the R9 295X2 had NVIDIA been willing to break PCIe power specs and increase noise.

UPDATE (6/13/14): Some of our readers seem to be pretty confused about things so I felt the need to post an update to the main story here. One commenter below mentioned that I was one of "many reviewers that pounded the R290X for the 'throttling issue' on reference coolers" and thinks I am going easy on NVIDIA with this story. However, there is one major difference that he seems to overlook: the NVIDIA results here are well within the rated specs. 

When I published one of our stories looking at clock speed variance of the Hawaii GPU in the form of the R9 290X and R9 290, our results showed that clock speed of these cards were dropping well below the rated clock speed of 1000 MHz. Instead I saw clock speeds that reached as low as 747 MHz and stayed near the 800 MHz mark. The problem with that was in how AMD advertised and sold the cards, using only the phrase "up to 1.0 GHz" in its marketing. I recommended that AMD begin selling the cards with a rated base clock and a typical boost clock instead only labeling with the, at the time, totally incomplete "up to" rating. In fact, here is the exact quote from this story: "AMD needs to define a "base" clock and a "typical" clock that users can expect." Ta da.

The GeForce GTX Titan Z though, as we look at the results above, is rated and advertised with a base clock of 705 MHz and a boost clock of 876 MHz. The clock speed comparison graph at the top of the story shows the green line (the card at stock) never hitting that 705 MHz base clock while averaging 894 MHz. That average is ABOVE the rated boost clock of the card. So even though the GPU is changing between frequencies more often than I would like, the clock speeds are within the bounds set by NVIDIA. That was clearly NOT THE CASE when AMD launched the R9 290X and R9 290. If NVIDIA had sold the Titan Z with only the specification of "up to 1006 MHz" or something like then the same complaint would be made. But it is not.

The card isn't "throttling" at all, in fact, as someone specifies below. That term insinuates that it is going below a rated performance rating. It is acting in accordance with the GPU Boost technology that NVIDIA designed.

Some users seem concerned about temperature: the Titan Z will hit 80-83C in my testing, both stock and overclocked, and simply scales the fan speed to compensate accordingly. Yes, overclocked, the Titan Z gets quite a bit louder but I don't have sound level tests to show that. It's louder than the R9 295X2 for sure but definitely not as loud as the R9 290 in its original, reference state.

Finally, some of you seem concerned that I was restrticted by NVIDIA on what we could test and talk about on the Titan Z. Surprise, surprise, NVIDIA didn't send us this card to test at all! In fact, they were kind of miffed when I did the whole review and didn't get into showing CUDA benchmarks. So, there's that.

Check out the fan on that Shadow Rock 2

The 120mm BeQuiet PureWings 2 that comes on the Shadow Rock 2 heatsink has a unique look with ripples on all the blades and can be mounted on any side of the cooler which could be handy for those with tall DIMM heatspreaders.  The heatsink weighs in just over a 1.1 kg and measures 159x122x149mm (6.25x4.8x5.8") with the fan attached which could be a tight squeeze in some systems.  FrostyTech hooked it up to their testbed and found it to be a very quiet cooler, especially on the low fan setting and relatively decent performance.  It is unlikely to show up on a top 10 list as it offers only reasonable performance and is quite expensive.

"In this review Frostytech is checking out the boxy BeQuiet's Shadow Rock 2 heatsink which stands 159mm tall and weighs in at 1120grams. This heatsink has a footprint of 122x122mm without a fan, 122x149mm with the supplied 1600-800rpm, 120mm PWM fan installed."

Welcome to The Machine

Subject: General Tech | June 12, 2014 - 12:42 PM |
Tagged: memristor, hp, the machine

HP is thinking of the long term as evidenced by their estimate of 2016 as the release date for the first viable DIMMs using memristors.  Their plans are much larger than a new type of memory, they are planning a scalable architecture dubbed The Machine which will take advantage of the high speed and lower power needs of memristors to develop a new type of system which will need to use photonic interconnects to keep up with the memristors.  They see this scaling from tiny devices and mobile phones with 100TB of storage to supercomputers whose speeds will make a mockery of the current record holder, the Fujitsu K.  Of course many of the claims The Register heard HP make should be taken with a grain of salt, after all the memristor was originally predicted to hit the market a year ago.  It is something to look forward to, who doesn't want faster, denser and more power efficient storage?

"The beleaguered IT giant plans to rejuvenate itself with a set of advanced technologies that, when combined, make a device called "The Machine" that can be as small as a smartphone and as large as a 160-rack supercomputer, the company announced at its HP Discover event in Las Vegas on Wednesday."

The care and feeding of your Haswell's memory controller

Subject: Memory | June 11, 2014 - 07:26 PM |
Tagged: CAS latency, ddr3-1600, ddr3-1866

X-bit Labs did testing of a variety of memory speeds on Haswell to determine if there is a point of diminishing returns at which point your well earned money is no longer bringing you better performance.  By setting up tests of two different DIMMs at set speeds, in this case DDR3-1600 and DDR3-1866 and varying the CAS Latency they tested to see if higher speeds or lower latency gave the best performance.  Using both synthetic benchmarks as well as gaming tests they determined that frequency is the key to better performance which makes sense considering the theoretical top frequency of 2933 MHz.  Check out all the benchmarks in their full review.

"The development of the new processor microarchitectures goes on and frequencies of contemporary types of DDR3 SDRAM grow as well. Is there any sense in using high-speed memory with modern Haswell processors? To answer this question, we have analyzed DDR3 frequency and timings influence on LGA 1150 platform performance."

There are Zombies on the Holodeck

With E3 2014 in full swing there are a lot of demos and trailers whetting our appetite and if the past is any proof, setting us up for disappointment as release dates move and features get dropped.  You can immediately scroll down to the long list below but first you really should take a look at Survios, once called Holodeck and then Prime, which uses an Oculus Rift, Razer Hydra, and PlayStation Move to immerse you in a zombie survival game; literally in first person.  The movie showing off the gameplay that Slashdot has linked to doesn't quite do justice to what the game will be like while wearing a Rift but the display behind does intimate just how much fun this style of gaming will be once it begins to mature.

"Ben Lang from Road to VR goes hands on and heads in with virtual reality technology company Survios' newest version of untethered VR system 'Prime 3'. He moves around the virtual space, holding and reloading weapons as you would in real life. 'At one point while playing, I was wielding the shotgun with two hands, with the table of weapons was on my right side. Several zombies were approaching and I needed a bit more fire power. I dropped the shotgun, reached over with my right hand to grab the tommy gun off the table, then virtually tossed it from my right hand to my left hand (because I'm a lefty), then pulled my pistol out of the holster with my right hand and continued to shoot both weapons.'"

Docker is headed for the big time

Subject: General Tech | June 11, 2014 - 12:33 PM |
Tagged: google, virtualization, linux, container, Linux Containerization, docker, Red Hat, ubuntu

Docker has put the libcontainer execution engine of their Linux Containerization onto Github, making it much easier to adopt their alternative virtualization technology and modify it for specific usage scenarios.  So far Google, Red Hat and Parallels have started adding their own improvements to the Go based libcontainer; adding to the Ubuntu dev team already at work. This collaboration should help containerization become a viable alternative to virtual machines and hopefully be included as a feature in future Linux distros.  Read more over at The Register.
