Yesterday, Lenovo unveiled two new gaming systems at IFA in Berlin. The new Y70 Touch is a 17-inch gaming notebook while the Erazer X310 and Erazer X315 are mid-tower desktops. All three systems will be available later this month.
The Y70 Touch is Lenovo's first desktop replacement notebook with a touchscreen. The 25.9mm thick notebook features a 17.3" 1080p display, backlit keyboard, and JBL-powered stereo speakers (with subwoofer). It can be configured with up to an Intel Haswell i7 processor, NVIDIA GTX 860M GPU with 4GB RAM, 16GB of DDR3 system memory, and 1TB solid state drive (SSD). (Storage options include 256GB, 512GB, and 1TB SSD options.) Lenovo is including an external disc drive with the gaming PC which was left out of the chassis itself to maintain its slim form factor and to reduce weight.
The Y70 Touch gaming notebook starts at $1,299 and will be available in the US later this month.
If desktops are more your style, Lenovo is now offering up the Erazer X310 and X315 mid-tower PCs. The X310 and X315 will share the same black mid-tower chassis but will use different internal hardware. the X310 with Intel Haswell CPUs will be available worldwide while the AMD APU-powered X315 will be exclusive to North America.
The ERAZER X310/X315 case is all black with a stealthy angular front panel design that hosts two 5.25" bays and a blue LED-backlit power button. The X310 can be configured with up to an Intel Haswell i7 CPU while the X315 supports AMD "Kaveri" APUs up to the A10 series (e.g. A10 7850K). Users can choose up to a NVIDIA GTX 760 (2GB) or AMD Radeon R9 255 (2GB) graphics card. The mid-tower has four PCI slots and in theory could support further DIY upgrades but GPU length would be limited and the power supply may need to be upgraded as well. Further, both systems feature up to 32GB system memory and a maximum of 4TB mechanical hard drive, 2TB hybrid hard drive or 256GB solid state storage.
The new ERAZER X310 and X315 desktops will be available shortly starting at $599.

The Tech Report took the new i7-5960X, Asus X99 Deluxe, 16 GB of Corsair Vengeance LPX DDR4, a Kingston HyperX SH103S3 240GB SSD and a XFX Radeon HD 7950 DD and set it loose on the test bench. The results were impressive to say the least, especially when they moved on from games to test productivity software where the Haswell architecture really shines. When they attempted to overclock the CPU they found a hard limit feeding the processor 1.3V and running 4.4GHz, any faster would cause some applications to BSoD. On the other hand that applied to all 8 cores and the difference in performance was striking.
Also make sure to read Ryan's review to get even mroe information on this long awaited chip.
"Haswell-E has arrived. With eight cores, 20MB of cache, and quad channels of DDR4 memory, it looks to be the fastest desktop CPU in history--and not by a little bit. We've tested the heck out of it and have a huge suite of comparisons going to back to the Pentium III 800. Just, you know, for context."

Revamped Enthusiast Platform
Join us at 12:30pm PT / 3:30pm ET as Intel's Matt Dunford joins us for a live stream event to discuss the release of Haswell-E and the X99 platform!! Find us at http://www.pcper.com/live!!
Sometimes writing these reviews can be pretty anti-climactic. With all of the official and leaked information released about Haswell-E over the last six to nine months, there isn't much more to divulge that can truly be called revolutionary. Yes, we are looking at the new king of the enthusiast market with an 8-core processor that not only brings a 33% increase in core count over the previous generation Ivy Bridge-E and Sandy Bridge-E platforms, but also includes the adoption of the DDR4 memory specification, which allows for high density and high speed memory subsystems.
And along with the new processor on a modified socket (though still LGA2011) comes a new chipset with some interesting new features. If you were left wanting for USB 3.0 or Thunderbolt on X79, then you are going to love what you see with X99. Did you think you needed some more SATA ports to really liven up your pool of hard drives? Retail boards are going to have you covered.
Again, just like last time, you will find a set of three processors that are coming into the market at the same time. These offerings range from the $999 price point and go down to the much more reasonable cost of $389. But this time there are more interesting decisions to be made based on specification differences in the family. Do the changes that Intel made in the sub-$1000 SKUs make it a better or worse buy for users looking to finally upgrade?
Haswell-E: A New Enthusiast Lineup from Intel
Today's launch of the Intel Core i7-5960X processor continues on the company's path of enthusiast branded parts that are built off of a subset of the workstation and server market. It is no secret that some Xeon branded processors will work in X79 motherboards and the same is true of the upcoming Haswell-EP series (with its X99 platform) launching today. As an enthusiast though, I think we can agree that it doesn't really matter how a processor like this comes about, as long as it continues to occur well into the future.
The Core i7-5960X processor is an 8-core, 16-thread design built on what is essentially the same architecture we saw released with the mainstream Haswell parts released in June of 2013. There are some important differences of course, including the lack of integrated graphics and the move from DDR3 to DDR4 for system memory. The underlying microarchitecture remains unchanged, though. Previously known as the Haswell-E platform, the Core i7-5960X continues Intel's trend of releasing enthusiast/workstation grade platforms that are based on an existing mainstream architecture.
Since the introduction of the Haswell line of CPUs, the Internet has been aflame with how hot the CPUs run. Speculation ran rampant on the cause with theories abounding about the lesser surface area and inferior thermal interface material (TIM) in between the CPU die surface and the underside of the CPU heat spreader. It was later confirmed that Intel had changed the TIM interfacing the CPU die surface to the heat spreader with Haswell, leading to the hotter than expected CPU temperatures. This increase in temperature led to inconsistent core-to-core temperatures as well as vastly inferior overclockability of the Haswell K-series chips over previous generations.
A few of the more adventurous enthusiasts took it upon themselves to use inventive ways to address the heat concerns surrounding the Haswell by delidding the processor. The delidding procedure involves physically removing the heat spreader from the CPU, exposing the CPU die. Some individuals choose to clean the existing TIM from the core die and heat spreader underside, applying superior TIM such as metal or diamond-infused paste or even the Coollaboratory Liquid Ultra metal material and fixing the heat spreader back in place. Others choose a more radical solution, removing the heat spreader from the equation entirely for direct cooling of the naked CPU die. This type of cooling method requires use of a die support plate, such as the MSI Die Guard included with the MSI Z97 XPower motherboard.
Whichever outcome you choose, you must first remove the heat spreader from the CPU's PCB. The heat spreader itself is fixed in place with black RTV-type material ensuring a secure and air-tight seal, protecting the fragile die from outside contaminants and influences. Removal can be done in multiple ways with two of the most popular being the razor blade method and the vise method. With both methods, you are attempting to separate the CPU PCB from the heat spreader without damaging the CPU die or components on the top or bottom sides of the CPU PCB.

Sorry for being about a month late to this news. Apparently, someone got their hands on an Intel Core i7-5960X and they wanted to see its eight cores. Removing the lid, they found that it was soldered directly onto the die with an epoxy, rather than coated with a thermal paste. While Haswell-E will still need to contend with the limitations of 22nm, and how difficult it becomes to exceed various clockspeed ceilings, the better ability to dump heat is always welcome.

While Devil's Canyon (Core i7 4970K) used better thermal paste, the method used with Haswell-E will be event better. I should note that Ivy Bridge-E, released last year, also contained a form of solder under its lid and its overclocking results were still limited. This is not an easy path to ultimate gigahertz. Even so, it is nice that Intel, at least on their enthusiast line, is spending that little bit extra to not introduce artificial barriers.

Tagged: Intel, haswell, tsx, errata
Transactional Synchronization Extensions, aka TSX, are a backwards compatible set of instructions which first appeared in some Haswell chips as a method to improve concurrency and multi-threadedness with as little work for the programmer as possible. It was intended to improve the scaling of multi-threaded apps running on multi-core processors and has not yet been widely adopted. The adoption has run into another hurdle, in some cases the use of TSX can cause critical software failures and as a result Intel will be disabling the instruction set via new BIOS/UEFI updates which will be pushed out soon. If your software uses the new instruction set and you wish it to continue to do so you should avoid updating your motherboard BIOS/UEFI and ask your users to do the same. You can read more about this bug/errata and other famous problems over at The Tech Report.
"The TSX instructions built into Intel's Haswell CPU cores haven't become widely used by everyday software just yet, but they promise to make certain types of multithreaded applications run much faster than they can today. Some of the savviest software developers are likely building TSX-enabled software right about now."

Introduction and Design
The next candidate in our barrage of ThinkPad reviews is the ThinkPad Yoga, which, at first glance, might seem a little bit redundant. After all, we’ve already got three current-gen Yoga models to choose from between the Yoga 2 11- and 13-inch iterations and the Yoga 2 Pro top-end selection. What could possibly be missing?
Well, in fact, as is often the case when choosing between well-conceived notebook models, it isn’t so much about what’s missing as it is priorities. Whereas the consumer-grade Yoga models all place portability, slimness, and aesthetics in the highest regard, the ThinkPad Yoga subscribes to a much more practical business-oriented approach, which (nearly) always instead favors function over form. It’s a conversation we’ve had here at PC Perspective a thousand times before, but yet again, it is the core ThinkPad philosophy which separates the ThinkPad Yoga from other notebooks of its type. Suffice it to say, in fact, that really the only reason to think of it as a Yoga at all is the unique hinge design and affiliated notebook/tablet convertibility; excepting that, this seems much closer to an X240 than anything in Lenovo’s current consumer-grade lineup. And carrying a currently-configurable street price of around $1,595 currently, it’s positioned as such, too.
But it isn’t beyond reproach. Some of the same questionable decisions regarding design changes which we’ve covered in our recent ThinkPad reviews still apply to the Yoga. For instance, the much-maligned clickpad is back, bringing with it vivid nightmares of pointer jumpiness and click fatigue that were easily the biggest complaint about the T440s and X240 we recently reviewed. The big question today is whether these criticisms are impactful enough to disqualify the ThinkPad Yoga as a rational alternative to other ThinkPad convertibles and the consumer-grade Yoga models. It’s a tall order, so let’s tackle it.
First up, the specs:
While most of this list is pretty conventional, the astute might have already picked out one particular item which tops the X240 we recently reviewed: a possible 16 GB of dual-channel RAM. The X240 was limited to just 8 GB of single-channel memory thanks to a mere single SODIMM slot. The ThinkPad Yoga also boasts a 1080p screen with a Wacom digitizer pen—something which is clearly superior to our X240 review unit. Sadly missing, however, are the integrated Gigabit Ethernet port and the VGA port—and the mini DisplayPort has been replaced by a mini-HDMI, which ultimately is decidedly inferior.

Introduction and Technical Specifications
Courtesy of MSI
The MSI Z97 XPower motherboard is the flagship board in their Overclocking Series line of motherboards, optimized over the previous version XPower board to take advantage of the Intel Z97 Express chipset and Intel 5th generation Core processors. The design and the layout of the board remain reminiscent of that from the Z87 XPower with several components shifted to other locations to open up space and other switched out to be replaced by updated technologies. The most obvious changes to the board are the inclusion of integrated water barbs in the CPU VRM sink and the reduction of the integrated CPU power phases to 16 (from 32-power phases on the previous generation board). The board's color scheme is less diverse as well, with all integrated components colored to match the black and yellow theme. At a base MSRP of $399.99, the Z97 XPower carries a premium price to match its premium feature set.
