Taking a half dozen PandaBoard ESes from Texas Instruments that have a 1.2GHz dual-core ARM Cortex-A9 processor onboard, Phoronix built a 12-core ARM machine to test out against AMD's E-350 APU as well as Intel's Atom Z530 and a Core i7 3770K.  Before you you make the assumption that the ARM's will be totally outclassed by any of these processors, Phoronix is testing performance per Watt and the ARM system uses a total of 31W when fully stressed and idles below 20W, which gives ARM a big lead on power consumption. 

Phoronix tested out these four systems and the results were rather surprising as it seems Intel's Ivy Bridge is a serious threat to ARM.  Not only did it provide more total processing power, its performance per Watt tended to beat ARM and more importantly to many, it is cheaper to build an i7-3770K system than it is to set up a 12-core ARM server.  The next generation of ARM chips have some serious competition.

"Last week I shared my plans to build a low-cost, 12-core, 30-watt ARMv7 cluster running Ubuntu Linux. The ARM cluster that is built around the PandaBoard ES development boards is now online and producing results... Quite surprising results actually for a low-power Cortex-A9 compute cluster. Results include performance-per-Watt comparisons to Intel Atom and Ivy Bridge processors along with AMD's Fusion APU."

A CPU Cooling Heatsink With Built In Computer From AMD

Tagged: nano-itx, heatsink, e-350, cooling, cooler master, CES, APU

At CES today we saw what at first resembles a Cooler Master V6 CPU heastink and fan combo. The processor cooler features a red 120mm fan housed in a black shroud which is then attached to the heatsink itself. The heatsink is a tower design with six copper heatpipes attached to a copper CPU block. The heatpipes then lead into a tower of aluminum fins to dissipate heat.

On the back of the unit; however, there's a little something extra in the form of a nano-itx motherboard and AMD E-350 APU based on the Brazos platform. The computer is self contained and provides a number of connectivity options. For more information on the Brazos platform and E-350 APU, see our preview and review articles. A quick run down of the E-350 specifications; however, is below.

  • Two Bobcat CPU cores at 1.6 GHz
  • A Radeon HD 6310 GPU with 80 processing cores running at 500 MHz
  • A TDP of 18 watts
  • DirectX 11 Graphics and DDR3 Memory Support

The bottom of the rear of the CPU cooler is the location of the nano-ITX motherboard's rear IO panel. The motherboard features Wi-Fi, HDMI, two USB 3.0 ports, two USB 2.0 ports, Gigabit Ethernet, VGA(?), and e-SATA(?) connections.

A side view of the Cooler Master heatsink is available below.

It's certainly a new idea, and it will definitely hit home for people that don't need or want to run their power hungry main desktop all the time. Because the system is self contained it does present some usability issues. Mainly that you will need to have a KVM or VNC connection to control it and the inside of the computer case is going to become a lot more crowded with cables. Further, it would be a pain to have to open up the main desktop system just to plug in a flash drive or cable. On the other hand, it'd make for a nice media or file server and would not require the desktop be on 24/7 without needing yet another box crowding my desk so I'd give it a shot. (The inside of my computer case is already a mess of wires so what do I have to lose?)

What are your thoughts on this somewhat strange CPU cooler?

Introduction and Design

P1040971.JPG

When the Apple MacBook Air originally debuted, geeks took note, and Windows laptop manufacturers ramped up efforts to meet that super-thin laptop on its own turf. Surprisingly, one of the first to respond was MSI, a company that is still struggling to define itself among a mainstream American market dominated by the likes of HP, Toshiba, Dell, and others.

MSI managed to significantly undercut the Air with its X340, but the build quality was also nowhere near what Cupertino’s engineers had managed. Yet MSI is not one to give up, and they’ve made moves to refine the X series over the years. As the price has dropped further, and the processor selection changed, comparisons to the Air have become less obvious. 

That’s particularly true with this latest MSI X370, which now makes use of the AMD E-350 Fusion APU. This processor is nothing new, and we’ve tested it before at PC Perspective. Yet this laptop is different from any previously we’ve reviewed product with this processor because of its size.

ECS Motherboards on display at Computex 2011

Tagged: x79, fusion, ECS, e-350, computex, 990fx

ECS, aka Elitegroup, had a large booth at Computex that focused more on its ODM aspects than consumer aspects, but there were still a couple of interesting designs to look at.

ecs01.jpg

The board we spotted was the new A990FXM-A motherboard that is of course based on the latest 990FX chipset from AMD.  Supporting the AM3+ processor socket and thus the pending AMD Bulldozer processors, the 990FX is going to be a long term product rather than a short term. One interesting addition to the board is found on the chipset heatsink that has a temperature reactive plastic on it that will turn from grey to orange-ish as the ambient case temperature increases.  This could be a great feature to easily gauge the heat level inside a windowed case.

Also an interesting move, ECS has elongated the receptacle on the 8-pin CPU power connection to make it easier to plug in and to remove.  If you have ever experienced a pinched finger or sliced finger nail from trying to reach down and unplug an ATX connector, you will see this as a nice addition.

ECS also had its X79 motherboard variant on display, showing the company's readiness for the pending Sandy Bridge-E release.

Also on the motherboard wall was the upcoming A75F-A with support for the AMD Llano Fusion-based processors that should be ready later in the summer.

Finally, a motherboard that we have just recently received for review purposes, the HDC-I is an AMD E-350 or E-240 Zacate platform mini-ITX form factor.  This solution might be a great option for users looking to build an HTPC box so be sure you check out our full review coming shortly.

Foxconn NT-A3500, AMD's Fusion E-350 is kicking Atom where it hurts

Subject: Systems | June 1, 2011 - 05:30 PM |
Tagged: nettop, e-350, amd

When it comes to tiny systems such as nettops, AMD's E-350 Fusion is doing what the Atom and ION combo can do, only faster, cooler and quieter.  While this is upsetting for NVIDIA and Intel, the consumer benefits almost as much as AMD does. techPowerUp just finished a review of a Foxconn product that demonstrates the abilities of the Fusion platform, the Netbox NT-A3500.  It is not for sale yet in North America but when it does hit the market you can expect around a $200 pricetag, plus RAM and a storage drive.  For that price you get the AMD E-350 and Radeon HD 6310 as well as Realtek ALC888S audio.  Wireless and wired LAN, four USB 2.0 and two USB 3.0 ports, optical audio and analog audio, and DVI and HDMI outputs.  techPowerUp covers the rest of the features in their full review.

"Foxconn has made some waves with their compact but very capable ION based NT-330I Netbox back in 2010. Now, almost a year later the market has evolved and Foxconn is sending their newest version into the race. The NT-A3500 is based on the AMD Fusion platform, aiming to be faster, cooler and quieter."
