Several rowboats worth of snacks, a couple of canoe-fulls of assorted beverages and boatloads of fun were had this weekend in the highly successful 7th Fragging Frogs VLAN; if you missed it there will be another chance some day but you really missed an epic event. There were over 120 Teamspeak connections in a variety of channels and an estimated peak of 78 active participants. Thanks to AMD there is a new game for the Frogs as well as Plants vs. Zombies Garden Warfare was a hit both to the players and to those watching iamApropos' live stream. We also gained some ARMA 2 fans which will not only appear again next VLAN but is also in danger of becoming a frequent activity for some members.
Once again there was quite a bit of valuable hardware and software given away, the list includes:
- AMD Fan Kit (headset, 16 GB USB drive, mouse)
- AMD Gaming Series RAM - 8 GB of 2133 Mhz
- MSI Military Class 4 A88XM-E35 FM2+ motherboard *and* A10-7850K APU
- AMD FX-8350 Processor
- XFX R9 290 Double D graphics card
- Several Plants vs Zombies: Garden Warfare Origin codes
AMD Red Team+
- Murdered Soul Suspect game codes
- Sniper Elite 3 game codes
Please stop by this thread to offer your thanks and support for all the hard work put into these events by Lenny, iamApropos, Spazster, Brandito, Cannonaire, AMD and the Frogs in general.

AMD has been showing off a reference Seattle-based server at Hot Chips and The Tech Report had an opportunity to see it. Eight 64-bit Cortex-A57 chips are set up in pairs, each pair sharing 1MB of L2 cache while the 8MB of L3 cache is accessible by all eight chips as well as the coprocessors, memory controller, and I/O subsystems. The system can address up to 128GB of DDR3 or DDR4, and you get support fot 8 SATA 6Gbps ports and 8 lanes of PCIe 3.0 to apportion between the slots. There is a secure System Control Processor, a partitioned Cortex-A5 core with its own ROM, RAM, and I/O to control power, boot and configuration control with support for TrustZone as well as a Cryptographic Coprocessor which accelerates all encryption processes as you might well expect. Read on for more information about AMD's unique new take on server technology.
"For some time now, the features of AMD's Seattle server processor have been painted in broad brush strokes. This morning, at the Hot Chips symposium, AMD is filling in most of the missing details. We were treated to an advance briefing last week, where AMD provided previously confidential information about Seattle's cache network, memory controller, I/O features, and coprocessors."

Today Acer unveiled a new Chromebook powered by an NVIDIA Tegra K1 processor. The aptly-named Chromebook 13 is 13-inch thin and light notebook running Google’s Chrome OS with up to 13 hours of battery life and three times the graphical performance of existing Chromebooks using Intel Bay Trail and Samsung Exynos processors.
The Chromebook 13 is 18mm thick and comes in a white plastic fanless chassis that hosts a 13.3” display, full size keyboard, trackpad, and HD webcam. The Chromebook 13 will be available with a 1366x768 or 1920x1080 resolution panel depending on the particular model (more on that below).
Beyond the usual laptop fixtures, external I/O includes two USB 3.0 ports, HDMI video output, a SD card reader, and a combo headphone/mic jack. Acer has placed one USB port on the left side along with the card reader and one USB port next to the HDMI port on the rear of the laptop. Personally, I welcome the HDMI port placement as it means connecting a second display will not result in a cable invading the mousing area should i wish to use a mouse (and it’s even south paw friendly Scott!).
The Chromebook 13 looks decent from the outside, but it is the internals where the device gets really interesting. Instead of going with an Intel Bay Trail (or even Celeron/Core i3), Acer has opted to team up with NVIDIA to deliver the world’s first NVIDIA-powered Chromebook.
Specifically, the Chromebook 13 uses a NVIDIA Tegra K1 SoC, up to 4GB RAM, and up to 32GB of flash storage. The K1 offers up four A15 CPU cores clocked at 2.1GHz, and a graphics unit with 192 Kepler-based CUDA cores. Acer rates the Chromebook 13 at 11 hours with the 1080p panel or 13 hours when equipped with the 1366x768 resolution display. Even being conservative, the Chromebook 13 looks to be the new leader in Chromebook battery life (with the previous leader claiming 11 hours).
A graph comparing WebGL performance between the NVIDIA Tegra K1, Intel (Bay Trail) Celeron N2830, Samsung Exynos 5800, and Samsung Exynos 5250. Results courtesy NVIDIA.
The Tegra K1 is a powerful little chip, and it is nice to see NVIDIA get a design win here. NVIDIA claims that the Tegra K1, which is rated at 326 GFLOPS of compute performance, offers up to three times the graphics performance of the Bay Trail N2830 and Exynos 5800 SoCs. Additionally, the K1 reportedly uses slightly less power and delivers higher multi-tasking performance. I’m looking forward to seeing independent reviews in this laptop formfactor and hoping that the chip lives up to its promises.
The Chromebook 13 is currently up for pre-order and will be available in September starting at $279. The Tegra K1-powered laptop will hit the United States and Europe first, with other countries to follow. Initially, the Europe roll-out will include “UK, Netherlands, Belgium, Denmark, Sweden, Finland, Norway, France, Germany, Russia, Italy, Spain, South Africa and Switzerland.”
Acer is offering three consumer SKUs and one education SKU that will be exclusively offering through a re-seller. Please see the chart below for the specifications and pricing.
|Acer Chromebook 13 Models||System Memory (RAM)||Storage (flash)||Display||Price MSRP|
|CB5-311-T9B0||2GB||16GB||1920 x 1080||$299.99|
|CB5-311-T1UU||4GB||32GB||1920 x 1080||$379.99|
|CB5-311-T7NN - Base Model||2GB||16GB||1366 x 768||$279.99|
|Educational SKU (Reseller Only)||4GB||16GB||1366 x 768||$329.99|
Intel made some waves in the Chromebook market earlier this year with the announcement of several new Intel-powered Chrome devices and the addition of conflict-free Haswell Core i3 options. It seems that it is now time for the ARM(ed) response. I’m interested to see how NVIDIA’s newest model chip stacks up to the current and upcoming Intel x86 competition in terms of graphics power and battery usage.
As far as Chromebooks go, if the performance is at the point Acer and NVIDIA claim, this one definitely looks like a decent option considering the price. I think a head-to-head between the ASUS C200 (Bay Trail N2830, 2GB RAM, 16GB eMMC, and 1366x768 display at $249.99 MSRP) and Acer Chromebook 13 would be interesting as the real differentiator (beyond aesthetics) is the underlying SoC. I do wish there was a 4GB/16GB/1080p option in the Chromebook 13 lineup though considering the big price jump to get 4GB RAM (mostly as a result of the doubling of flash) in the $379.99 model at, say, $320 MSRP.

Tagged: ssd, radeon r7, confusing, amd, 19nm
In a branding move that has no possibility of causing confusion, AMD has announce the name of their new SSD line and it seems that the next Radeon R7 240 you buy might be a GPU or then again it might not be. Brand confusion aside, the drives will use 19nm Toshiba NAND fabbed at SanDisk and are predicted to perform similar to other drives with the same NAND, reads of 550MBps and 530MBps write. However as we well know the key to performance lies in the controller and the number of channels so it will be interesting to see the first benchmarks. As The Inquirer points out this could lead to the release of AMD branded machines, containing AMD made APU, RAM, SSD and discrete GPU.
"The Radeon R7 range consisting of 120GB, 240GB and 480GB flavours and is designed to appeal to the gaming market, putting it in direct competition with Micron's Crucial range which expanded to include the MX100, which premiered earlier this year claiming 89 percent performance improvement over a standard hard drive."

Tagged: ssd, phase change memory, PCM, hgst, FMS 2014, FMS
According to an HGST press release, the company will bring an SSD based on phase change memory to the 2014 Flash Memory Summit in Santa Clara, California. They claim that it will actually be at their booth, on the show floor, for two days (August 6th and 7th).
The device, which is not branded, connects via PCIe 2.0 x4. It is designed for speed. It is allegedly capable of 3 million IOPS, with just 1.5 microseconds required for a single access. For comparison, the 800GB Intel SSD DC P3700, recently reviewed by Allyn, had a dominating lead over the competitors that he tested. It was just shy of 250 thousand IOPS. This is, supposedly, about twelve times faster.
While it is based on a different technology than NAND, and thus not directly comparable, the PCM chips are apparently manufactured at 45nm. Regardless, that is significantly larger lithography than competing products. Intel is manufacturing their flash at 20nm, while Samsung managed to use a 30nm process for their recent V-NAND launch.
What does concern me is the capacity per chip. According to the press release, it is 1Gb per chip. That is about two orders of magnitude smaller than what NAND is pushing. That is, also, the only reference to capacity in the entire press release. It makes me wonder how small the total drive capacity will be, especially compared to RAM drives.
Of course, because it does not seem to be a marketed product yet, nothing about pricing or availability. It will almost definitely be aimed at the enterprise market, though (especially given HGST's track record).
*** Update from Allyn ***
I'm hijacking Scott's news post with photos of the actual PCM SSD, from the FMS show floor:
In case you all are wondering, yes, it does in fact work:
One of the advantages of PCM is that it is addressed at smaller sections as compared to typical flash memory. This means you can see ~700k *single sector* random IOPS at QD=1. You can only pull off that sort of figure with extremely low IO latency. They only showed this output at their display, but ramping up QD > 1 should reasonably lead to the 3 million figure claimed in their release.

The new cooling on the 290X tends to have it at the top of the gaming charts and with the impending release of two new FirePro HPC cards AMD looks to take the productivity title away from the Tesla K40. The higher end S9150 boasts 16GB GDDR5 memory with a 512-bit memory interface, 44 GCN compute units with 64 stream processors each there is a total of 2816 stream processors on board. That equates to 5.07 TFLOPS peak single-precision 2.53 TFLOPS peak double-precision performance with theoretical memory bandwidth of 320GB per second. AMD expects the S9150 to have support for OpenCL 2.0 drivers by the end of the year, which the lower priced and specced S9050 will not though both will support AMD Stream technology and OpenCL 1.2. Check them out at The Register.
"The company's new big gun is the FirePro S9150 card, which maxes out at a blistering 5.07 TFLOPS peak single-precision floating-point performance and 2.53 TFLOPS peak double-precision performance."

Tagged: origin, on the house, free, free games
Origin, with its On the House program, has been releasing games for free, to promote their distribution platform. This time, they dug deep in the back catalog and pulled out Wing Command 3: Heart of the Tiger. This DOS-era game is the last of the three focused on "The Confederation" versus "The Kilrathi". It was also the first to use "full motion video", headlined by Mark Hamill, rather than animated cutscenes. "On the House" makes it free forever, if you declare your interest before the promotion ends.
It is also available at Good Old Games, for $5.99, but it does go on sale from time to time. At the very least, it is probably worth picking it up on Origin and, if you like it, pick up the DRM-free version at GoG.com for safe archival.
And if you don't like it? Well, you're not out much, are you?

Tagged: keyboard, travel keyboard, htpc keyboard
So, I am writing about a wireless, non-mechanical keyboard.
Mad Catz has made a weird keyboard layout. Honestly, it looks like something from a 1990's-era sci-fi video game. I could imagine "Lev Arris" pulling it out of his trench coat while discussing space pirates. It also includes mouse and media functionality, even when pairing with Android and iOS devices (it connects with Macs and PCs, too). It's also small.
As stated earlier, its keys are not mechanical. They are, also, not membrane-dome. The keys are based on scissor-switches, common with laptop keyboards. While I do not know the specifics of this keyboard, I do not know of any scissor-switch keyboard with removable keys. This means that, if something gets stuck under a keycap, you cannot remove it (unless you intend to never put it back on). Again, Mad Catz could have done something special, but it is something to think about -- especially if you intend on using this keyboard in the living room while eating.
The keyboard has an adjustable, white backlight for the "main" keys. It is, also, $100. This is definitely a unique design, tailored for a living room (or hotel room) experience. It is not cheap, but interesting. I could see it being useful, especially if a user could use it for both their living room, and during travel.
