Submission + - Errata prompts Intel to disable TSX in Haswell, early Broadwell CPUs

Dr. Damage writes: 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.

Unfortunately, that work may have to come to a halt, thanks to a bug—or "errata," as Intel prefers to call them—in Haswell's TSX implementation that can cause critical software failures. To work around the problem, Intel will disable TSX via microcode in its current CPUs--and in early Broadwell processors, as well.

Submission + - Intel's 14-nm Broadwell CPU primed for slim tablets

crookedvulture writes: Intel's next-gen Broadwell processor has entered production, and we now know a lot more about what it entails. The chip is built using 14-nm process technology, enabling it to squeeze into half the power envelope and half the physical footprint of last year's Haswell processors. Even the thickness of the CPU package has been reduced to better fit inside slim tablets. There are new power-saving measures, too, including a duty cycle control mechanism that shuts down sections of the chip during some clock cycles. The onboard GPU has also been upgraded with more functional units and hardware-assisted H.265 decoding for 4K video. Intel expects the initial Broadwell variant, otherwise known as the Core M, to slip into tablets as thin as the iPad Air. We can expect to see the first systems on shelves in time for the holidays.

Submission + - Surface Pro 3 has 12" screen, Intel inside

crookedvulture writes: Microsoft unveiled its Surface Pro 3 tablet at a press event in New York this morning. The device has a larger 12" screen with a 2160x1440 display resolution and a novel 3:2 aspect ratio. Intel Core processors provide the horsepower, starting with the Core i3 in the base model and extending all the way up to Core i7 in pricier variants. The tablet is just 9.1 mm thick, which Microsoft claims is the thinnest ever for a Core-based device. Microsoft developed a new radial fan that's suppose to distribute airflow evenly inside the chassis without generating audible noise. The tablet weights 800 g, shaving 100 g off the Surface Pro 2, and it's supposed to have longer battery life, as well. Microsoft has also rolled out new keyboard accessories, a pressure-sensitive stylus, and a docking station that supports 4K video output. The Surface Pro 3 is scheduled to be available tomorrow with prices starting at $799.

Submission + - AMD designing all-new CPU cores for ARMv8, x86

crookedvulture writes: AMD just revealed that it has two all-new CPU cores in the works. One will be compatible with the 64-bit ARMv8 instruction set, while the other is meant as an x86 replacement for the Bulldozer architecture and its descendants. Both cores have been designed from the ground up by a team led by Jim Keller, the lead architect behind AMD's K8 architecture. Keller worked at Apple on the A4 and A4 before returning to AMD in 2012. The first chips based on the new AMD cores are due in 2016.

Submission + - Wireless PCIe to enable remote graphics cards (techreport.com) 1

J. Dzhugashvili writes: If you read Slashdot, odds are you already know about WiGig and the 7Gbps wireless networking it promises. The people at Atheros and Wilocity are now working on an interesting application for the spec: wireless PCI Express. In a nutshell, wPCIe enables a PCI Express switch with local and remote components linked by a 60GHz connection. The first applications, which will start sampling next year, will let you connect your laptop to a base station with all kinds of storage controllers, networking controllers, and yes, an external graphics processor. wPCIe works transparently to the operating system, which only sees additional devices connected over PCI Express. And as icing on the cake, wPCie controllers will lets you connect to standard Wi-Fi networks, too.

Submission + - SSDs clash with hard drives in value comparison (techreport.com)

EconolineCrush writes: SSDs hardly offer compelling value on the cost-per-gigabyte scale. But what if one considers performance per dollar? This article takes a closer look at the value proposition offered by today's most common SSDs, mixing raw performance data with each drive's cost, both per gigabyte and as a component of a complete system. An even dozen SSD configurations are compared, and results from a collection of mechanical hard drives provides additional context. The data are laid out in detailed scatter plots that clearly illustrate the most favorable intersections of price and performance, and you might be surprised to see just how well the SSDs fare versus traditional hard drives. A few of the SSDs offer much better value than their solid-state competition, too.

Submission + - Hybrid Seagate hard drive has performance issues (techreport.com)

EconolineCrush writes: The launch of Seagate's Momentus XT hard drive made news on Slashdot last week, and for good reason. While not the first hybrid hard drive on the market, the XT is the only one that sheds Windows' ReadyDrive scheme for an OS-independent approach Seagate calls Adaptive Memory. While early coverage of the XT was largely positive, more detailed analysis reveals a number of performance issues, including poor sequential read throughput and an apparent problem with command queuing. In a number of tests, the XT is actually slower than Seagate's year-old Momentus 7200.4, a drive that costs $40 less!

Submission + - Intel targets AMD with affordable unlocked CPUs (techreport.com) 3

EconolineCrush writes: For years, AMD has catered to gamers and enthusiasts with mid-range Black Edition processors whose unlocked multipliers make overclocking easy. Intel has traditionally reserved unlocked multipliers for its ultra-expensive Extreme CPUs, but it has now brought the feature to affordable models that compete directly with AMD's most popular processors. The Core i5-655K and Core i7-875K have two and four cores, respectively, and they're priced at just $216 and $342. It appears that both will easily hit speeds in excess of 4GHz with air cooling. Surprisingly, even at stock speeds, the i7-875K offers better performance and power efficiency per dollar than just about any other desktop CPU out there.

Submission + - Asus budget ultraportable notebook sold sans OS (techreport.com)

EconolineCrush writes: Tired of paying the Windows tax on notebooks? Asus' Eee PC 1201T budget ultraportable comes without a traditional operating system and sells for only $380. The 12" system has promising specifications, sporting an Athlon Neo processor, Radeon HD 3200 graphics, Bluetooth, and 802.11n Wi-Fi. It weighs just 3.2lbs with a 6-cell battery and can even handle light gaming duties. However, battery life in Ubuntu is considerably shorter than it is under Windows. Are there any better options for would-be laptop Linux users?

AMD Multi-Display Tech Has Problems, Potential 138

EconolineCrush writes "While AMD's Eyefinity multi-display gaming tech is undeniably impressive at first glance, digging deeper reveals key limitations. Some games work well, others not at all, and many are simply better suited to specific screen configurations. A three-way setup looks to be ideal from a compatibility perspective, and given current LCD prices, it's really not all that expensive. But would you take that over a single high-resolution display or a giant HDTV?"

Submission + - AMD undercuts Intel with six-core Phenom IIs (techreport.com) 1

EconolineCrush writes: As Slashdot readers are no doubt aware, Intel's latest "Gulftown" Core i7-980X is an absolute beast of a CPU. But its six cores don't come cheap; the 980X sells for over a grand, which is more than it would cost to build an entire system based on one of AMD's new six-core CPUs. The Phenom II X6 line starts at just $200 and includes a new Turbo capability that can opportunistically raise the clock speed of up to three cores when the others are idle. Although not as fast as the 980X, the the new X6s are quick enough to offer compelling value versus even like-priced Intel CPUs. And the kicker: the X6s will work in a good number of older Socket AM2+ and AM3 motherboards with only a BIOS update.

WD, Intel, Corsair, Kingston, Plextor SSDs Collide 56

J. Dzhugashvili writes "New SSDs just keep coming out from all corners of the market, and keeping track of all of them isn't the easiest job in the world. Good thing SSD roundups pop up every once in a while. This time, Western Digital's recently launched SiliconEdge Blue solid-state drive has been compared against new entrants from Corsair, Kingston, and Plextor. The newcomers faced off against not just each other, but also Intel's famous X25-M G2, WD's new VelociRaptor VR200M mechanical hard drive, and a plain-old WD Caviar Black 2TB thrown in for good measure. Who came out on top? Priced at about the same level, the WD and Plextor drives each seem to have deal-breaking performance weaknesses. The Kingston drive is more affordable than the rest, but it yielded poor IOMeter results. In the end, the winner appeared to be Corsair's Nova V128, which had similar all-around performance as Intel's 160GB X25-M G2 but with a slightly lower capacity and a more attractive price." Thanks to that summary, you might not need to wade through all 10 of the pages into which the linked article's been split.
