At the keynote of the GPU Technology Conference (GTC) today, NVIDIA CEO Jen-Hsun Huang disclosed some more updates on the roadmap for future GPU technologies.

Most of the detail was around Pascal, due in 2016, that will introduce three new features including mixed compute precision, 3D (stacked) memory, and NVLink. Mixed precision is a method of computing in FP16, allowing calculations to run much faster at lower accuracy than full single or double precision when they are not necessary. Keeping in mind that Maxwell doesn't have an implementation with full speed DP compute (today), it would seem that NVIDIA is targeting different compute tasks moving forward. Though details are short, mixed precision would likely indicate processing cores than can handle both data types.

3D memory is the ability to put memory on-die with the GPU directly to improve overall memory banwidth. The visual diagram that NVIDIA showed on stage indicated that Pascal would have 750 GB/s of bandwidth, compared to 300-350 GB/s on Maxwell today.

NVLink is a new way of connecting GPUs, improving on bandwidth by more than 5x over current implementations of PCI Express. They claim this will allow for connecting as many as 8 GPUs for deep learning performance improvements (up to 10x). What that means for gaming has yet to be discussed.

NVIDIA made some other interesting claims as well. Pascal will be more than 2x more performance per watt efficient than Maxwell, even without the three new features listed above. It will also ship (in a compute targeted product) with a 32GB memory system compared to the 12GB of memory announced on the Titan X today. Pascal will also have 4x the performance in mixed precision compute.

NVIDIA Quadro M6000 Leaks via Deadmau5

Sometimes information comes from the least likely of sources. Deadmau5, one of the world's biggest names in house music, posted an interesting picture to his Instagram feed a couple of days ago.

Well, that's interesting. A quick hunt on Google for the NVIDIA M6000 reveals rumors of it being a GM200-based 12GB graphics card. Sound familiar? NVIDIA recently announced the GeForce GTX TITAN X based on an identical configuration at GDC last week.

A backup of the Instagram image...in case it gets removed.

With NVIDIA's GPU Technology Conference coming up starting this Tuesday, it would appear we have more than one version of GM200 incoming.

NVIDIA Releases GeForce GTX 960M and GTX 950M Mobile Graphics

NVIDIA has announced new GPUs to round out their 900-series mobile lineup, and the new GTX 960M and GTX 950M are based on the same GM107 core as the previous 860M/850M parts.

geforce-gtx-960m-3qtr.png

Both GPUs feature 640 CUDA Cores and are separated by Base clock speed, with the GTX 960M operating at 1096 MHz and GTX 950M at 914 MHz. Both have unlisted maximum Boost frequencies that will likely vary based on thermal constraints. The memory interface is the other differentiator between the GPUs, with the GTX 960M sporting dedicated GDDR5 memory, and the GTX 950M can be implemented with either DDR3 or GDDR5 memory. Both GTX 960M and 950M use the same 128-bit memory interface and support up to 4GB of memory.

As reported by multiple sources the core powering the 960M/950M is a GM107 Maxwell GPU, which means that we are essentially talking about rebadged 860M/850M products, though the unlisted Boost frequencies could potentially be higher with these parts with improved silicon on a mature 28nm process. In contrast the previously announced GTX 965M is based on a cut down Maxwell GM204 GPU, with its 1024 CUDA Cores representing half of the GPU core introduced with the GTX 980.

New notebooks featuring the GTX 960M have already been announced by NVIDIA's partners, so we will soon see if there is any performance improvement to these refreshed GM107 parts.

MSI Announces 4GB Version of NVIDIA GeForce GTX 960 Gaming Graphics Card

Manufacturers announcing 4GB versions of the GeForce GTX 960 has become a regular occurrence of late, and today MSI has announced their own 4GB GTX 960, adding a model with this higher memory capacity to their popular MSI Gaming graphics card lineup.

The GTX 960 Gaming 4GB features an overclocked core in addition to the doubled frame buffer, with 1241MHz Base, 1304MHz Boost clocks (compared to the stock GTX 960 1127MHz Base, 1178MHz Boost clocks). The card also features their proprietary Twin Frozr V (5 for non-Romans) cooler, which they claim surpasses previous generations of their Twin Frozr coolers "by a large margin", with a new design featuring their SuperSU heat pipes and a pair of 100mm Torx fans with alternating standard/dispersion fan blades.

The card is set to be shown at the Intel Extreme Masters gaming event in Poland later this week, and pricing/availability have not been announced.

It has been a rough quarter for the tech industry

Tagged: Q1, gigabyte, earnings, msi, TSMC, amd, Intel, nvidia

There is quite a bit of news on how various component manufacturers have fared at the beginning of 2015 and not much of it is good.  Gigabyte has seen revenues drop almost 20% compared to this time last year and a significantly higher overall drop and while MSI is up almost 4% when compared to this quarter in 2014, February saw a drop of over 25% and over the total year a drop of nearly 8%.  TSMC has taken a hit of 28% over this month though it is showing around 33% growth over the past year thanks to its many contract wins over the past few months.  Transcend, Lite-On and panel maker HannStar all also reported losses over this time as did overseas notebook designers such as Wistron, Compal and Inventec.

Intel is doing well though perhaps not as profitably as they would like, and we know that NVIDIA had a great 2014 but not primarily because of growth in the market but by poaching from another company which has been struggling but not as much as previous years.  The PC industry is far from dead but 2014 was not a kind year.

"Gigabyte Technology has reported consolidated revenues of NT$3.216 billion (US$101.93million) for February 2015, representing a 39.31% drop on month and 26.75% drop on year.

The company has totaled NT$8.515 billion in year-to-date revenues, down 18.47% compared with the same time last year."

Introduction and Design

P9260212.jpg

Although the target market and design emphasis may be different, there is one thing consumer and business-grade laptops have in common: a drift away from processing power and toward portability and efficiency.  At the risk of repeating our introduction for the massive MSI GT72 gaming notebook we reviewed last month, it seems that battery life, temperature, and power consumption get all the attention these days.  And arguably, it makes sense for most people: it’s true that CPU performance gains have in years past greatly outstripped the improvements in battery life, and that likewise performance gains could be realized far more easily by upgrading storage device speed (such as by replacing conventional hard drives with solid-state drives) than by continuing to focus on raw CPU power and clock rates.  As a result, we’ve seen many mobile CPU speeds plateauing or even dropping in exchange for a reduction in power consumption, while simultaneously cases have slimmed and battery life has jumped appreciably across the board.

But what if you’re one of the minority who actually appreciates and needs raw computing power?  Fortunately, Lenovo’s ThinkPad W series still has you covered.  This $1,500 workstation is the business equivalent of the consumer-grade gaming notebook.  It’s one of the few designs where portability takes a backseat to raw power and ridiculous spec.  Users shopping for a ThinkPad workstation aren’t looking to go unplugged all day long on an airplane tray table.  They’re looking for power, reliability, and premium design, with function over form as a rule.  And that’s precisely what they’ll get.

Beyond the fairly-typical (and very powerful) Intel Core i7-4800MQ CPU—often found in gaming PCs and workstations—and just 8 GB of DDR3-1600 MHz RAM (single-channel) is a 256 GB SSD and a unique feature to go along with the WQHD+ display panel: built-in X-Rite Pantone color sensor which can be used to calibrate the panel simply by closing the lid when prompted.  How well this functions is another topic entirely, but at the very least, it’s a novel idea.
