The Killer 1535 Wi-Fi adapter was the first 2x2 MU-MIMO compatible adapter on the market when it launched earlier this year, and is only found in a few products right now. We had a chance to test it out with the recently reviewed MSI G72 Dominator Pro G-Sync laptop, using the new Linksys EA8500 MU-MIMO router. How did it perform, and just what is MU-MIMO? Read on to find out!
Killer networks certainly haven’t skimped on the hardware with their new wireless adapter, as the Wireless-AC 1535 features two external 5 GHz signal amplifiers and is 802.11ac Wave 2 compliant with its support for MU-MIMO and Transmit Beamforming. And while the adapter itself certainly sounds impressive the real star here – besides the MU-MIMO support – is the Killer software. With these two technologies Killer has a unique product on the market, and if it works as advertised it would create an attractive alternative to the typical Wi-Fi solution.
MU-MIMO: What is it?
With an increasing number of devices using Wi-Fi in the average connected home the strain on a wireless network can often be felt. Just as one download can bring your internet connection to a crawl, one computer can hog nearly all available bandwidth from your router. MU-MIMO offers a solution to the network limitations of a typical multi-user home, and in fact the MU in MU-MIMO stands for Multi-User. The technology is part of the Wave 2 spec for 802.11ac, and it works differently than standard MIMO (multiple input, multiple output) technology. What’s the difference?
With standard MIMO (also known as Single-User MIMO) compatible devices take advantage of multiple data streams that are propagated to provide faster data than would otherwise be available for a single device. Multiple antennas on both base station and the client device are used to create the multiple transmit/receive streams needed for the added bandwidth. The multiple antennas used in MIMO systems create multiple channels, allowing for those separate data streams, and the number of streams is equal to the number of antennas (1x1 supports one stream, 2x2 supports two streams, etc.).

Lenovo has unveiled their reinvented their ideapad (now all lowercase) lineup at IFA 2015 in Berlin, and the new laptops feature updated processors including Intel Braswell and Skylake, as well as some discrete AMD and NVIDIA GPU options.
At the entry-level price-point we find the ideapad 100S which does not contain one of the new Intel chips, instead running an Intel Atom Z3735F CPU and priced accordingly at just $189 for the 11.6” version and $259 for the 14” model. While low-end specs (2GB RAM, 32GB/64GB eMMC storage, 1366x768 screen) aren’t going to blow anyone away, these at least provide a Windows 10 alternative to a Chromebook at about the same cost, and to add some style Lenovo is offering the laptop in four colors: blue, red, white, and silver.
Moving up to the 300S we find a 14” laptop (offered in red, black, or white) with Intel Pentium Braswell processors up to the quad-core N3700, and the option of a FHD 1920x1080 display. Memory and storage options will range up to 8GB DDR3L and up to either 256GB SSD or 1TB HDD/SSHD. At 0.86" thick the 300S weighs 2.9 lbs, and prices will start at $479.
A lower-cost ideapad 300, without the “S” and with more basic styling, will be available in sizes ranging from 14” to 17” and prices starting between $399 and $549 for their respective models. A major distinction will be the inclusion of both Braswell and Intel 6th Gen Skylake CPUs, as well at the option of a discrete AMD GPU (R5 330M).
Last we have the ideapad 500S, available in 13.3”, 14”, and 15.6” versions. With Intel 6th Gen processors up to Core i7 like the 300S, these also offer optional NVIDIA GPUs (GTX 920M for the 13.3", 940M for the 14"+) and up to FHD screen resolution. Memory and storage options range up to 8GB DDR3L and up to either 256GB SSD or 1TB HDD/SSHD, and the 500S is a bit thinner and lighter than the 300S, with the 13.3” version 0.76” thick and 3.4 lbs, moving up to 0.81” and 4.6 lbs with the 15.6” version.
A non-S version of the ideapad 500 will also be available, and this will be the sole AMD CPU representative with the option of an all-AMD solution powered by up to the A10-7300 APU, or a combination of R7 350M graphics along with 6th Gen Intel Core processors. 14” and 15” models will be available starting at $399 for the APU model and $499 with an Intel CPU.
All of the new laptops ship with Windows 10 as Microsoft’s newest OS arrived just in time for the back-to-school season.

MSI has been busy at this year’s Computex trade show. In addition to the company’s graphics cards and motherboard displays, MSI is showing off four new G Series gaming notebooks. Three of them are running Intel Ivy Bridge processors while the fourth machine is powered by a top-end AMD Trinity APU. Included in the new G series is the GT70, GT60, GE70, GE60, and GX60. The only AMD system is the GX60. Let’s take a look at that one first.
The GX60 has a similar exterior build as the other G Series notebooks, but has vastly different internals and does not appear to have the same audio technology as the Intel-based notebooks. The desktop replacement class (read: heavy and not so great battery life heh) laptop features an AMD A10-4600M APU, AMD A70M chipset, and AMD Radeon 7970M graphics card. Other features include MSI’s “SuperRAID” storage with up to two SSDs in RAID and a mechanical hard drive, Steelseries keyboard, and a Killer E2200 gaming network card. Another interesting feature is the system’s ability to output to up to three displays with AMD Eyefinity technology. The system was able to pull a respectable 30 frames per second on the Unigine Heave benchmark and will have an MSRP of around 1,000 British Pounds (~$1,557.70 USD). According to eTeknix, the AMD Trinity-based notebook will be available soon.
The Intel Ivy Bridge based systems get a bit more love than the AMD Trinity system with SuperRAID support, up to 32GB of RAM, MSI Audio Boost (powered by Dynaudio or THX TruStudiio Pro depending on model), gold-plated audio connectors, Turbo Drive Engine and NVIDIA discrete graphics. The Intel and AMD G series laptops all get 1080p displays and custom backlit keyboards built by SteelSeries. The AMD system may well have MSI Audio Boost, gold plated connectors, and the like but MSI did not seem to tout them on the GX60 like they did for the Intel ones. The GX60 does at least get the SteelSeries keyboard and SuperRAID tech. Anyway, onto the Intel gaming rigs.
MSI GT70 and GT60
The MSI GT 70 is the largest and fastest gaming notebook at the MSI booth with a 17” 1080p display, quad core Core i7 processor, SuperRAID storage, THX certified Dynaudio sound, Turbo Drive Engine, Killer E2200 NIC, and a NVIDIA GTX 680M mobile GPU with GDDR5 RAM. The GT70 utilizes MSI’s SuperRAID to the fullest with two SSDs and a mechanical hard drive for up to 700MB/s read speeds. The system further features a backlit keyboard from SteelSeries that has five LED pattern modes (Normal, Gaming, Wave, Breathing, and Dual Color) and various selectable colors to choose from. The GT70 was pulling about 45 frames-per-second on the Unigine Heaven benchmark and P20,000 on 3DMark Vantage. Consumers should expect it to be available for around 2,500 British Pounds (~$3,894.25 USD).
The MSI GT70 gaming notebook
The GT60 is a smaller version of the GT70 with 15.6” chassis, slightly slower Ivy Bridge Core i7 processor at 2.9GHz, and only a GTX 670M graphics card. It features the same MSI technology as its bigger brother, the GT70, but may not have the exact SuperRAID setup. Otherwise it has Dynaudio, 1080p display, the backlit SteelSeries keyboard, and lots of other goodies. No price info on this one to report, unfortunately.
MSI GE70 and GE60
The two MSI GE branded gaming laptops are the budget versions of the GT70 and GT60. They feature slower IVY Bridge processors, a downgrade in the Intel chipset to H76M, and a GPU downgrade to a NVIDIA GT650M with 2GB of GDDR5 memory. The displays are still 1080p, but they do not have Dynaudio (only THX TruStudio Pro), and the SteelSeries keyboards are not backlit. Of the two, the GE70 has a slightly faster Intel processor. They do both feature Turbo Drive Engine technology and likely SuperRAID though the setups are likely limited versus the bigger GT70’s chassis. Again, no word on how much these will cost or when they will be shipping.
All the notebooks have a nice black finish to them and the SteelSeries keyboard looks pretty nice. I’m interested in the AMD GX60 myself as I find Trinity neat. The Intel-based systems are definitely power houses though, especially the GT70 and although I don’t expect battery life to be anywhere near great these would be a good choice for gamers that demand the portability of a laptop platform.
Update: the press release does clarify that the GT70 and GE70 have 17.3” 1080p screens while the GT60 and GE60 have 15.6” 1080p screens. It also lists USB 3.0 compatibility on the Intel-based notebooks along with a built-in 720p 30fps webcam for video conferencing.

ZDNet and others published articles discussing the rising prices of PCs: it needs a grain of salt.
News publications love to publish large stories about how an industry is forcibly altered. For instance, are you sick of stories proclaiming the term “Post PC” yet? It is the season’s fashion to paint darker tones over any portrait of the personal computer.
According to a report from Ben Reitzes of Barclays Capital, certain PC components have gotten more expensive due to a series of recent events. It does not look like such a bleak future, however. Granted, ZDNet and Barclays Capital are both focused on their investment-oriented customers, but still.
As you can clearly see, the PC is doomed.
Image from Don McMillan presentation.
Foremost on the list of concerns is the elevated price of hard drives. ZDNet claims that Apple will have an advantage due to their switch to solid state devices in Macbook Airs and iPads. Apple does not have an advantage -- anyone can put an SSD in their devices, and many PC manufacturers who sell their product for a base price of a thousand dollars do if it suits the goal of the product.
LCD panels are expected to elevate in the near future as OEMs build up inventory ahead of the launch of Windows 8-based products. I am sorry, but come on. Prices of components tend to rise when you abruptly spike in sales. Moving on…
DRAM prices have also risen about 7 percent compared to just a few months ago. My issue is that RAM prices have absolutely plummeted since even just last year. For a PC which costs four hundred dollars, RAM is expected to make up just $15 of that. 7 percent on $15 is, for all practical purposes, a rounding error for a $400 device.
The sky is not falling.

Vizio is commonly known for its line of televisions aimed at the value and price/performance markets; however, the company is moving into the computer market with a series of budget all-in-one desktop and laptop computers. Business Insider reports that the aluminum housed PCs include two all-in-one desktops and three laptop computers and will be shown off at CES 2012.
The desktops come in a 24" and 27" model, and include a screen, base, aluminum keyboard, trackpad, and subwoofer (left and right speakers likely integrated in monitor part).
The laptops come in two 15" models and one 14" computer. The 14" and one of the 15" laptops are described at being "ultra-thin." From one of the photos, at least one of the laptops will support USB 3.0.
Unfortunately, there is little word on specifications but they will likely be on hand at CES so stay tuned to PC Perspective for more details. Vizio states that the computers will be able to stream data back and forth between the computer and Vizio Smart TVs, and will be available for purchase around June. More photos of the devices can be found here.
