To say that I was very impressed by the Toshiba R700 on paper would be an understatement. Even with very little actual hands-on time with the notebook, I put it in my mobile buyer's guide as my pick for road warriors. I got Toshiba to send me a review unit to see if the R700 was as impressive in day-to-day use as it is on paper and found that while the configuration they sent me was not so great, the rest of the R700 lineup represents a fantastic value for money and is a great choice for mobile use.

Last night LG announced that it would be using NVIDIA's Tegra 2 in its Optimus Series smartphones starting in Q4 2010. The most exciting part of Tegra 2 is its use of two ARM Cortex A9 cores. The Cortex A9 is ARM's first out-of-order architecture and should deliver a performance boost similar, at worst, to what we saw in the ARM11 to Cortex A8 transition. But NVIDIA isn't the only company working on a Cortex A9 SoC.

Samsung was unwilling to talk about its Cortex A9 plans at CES, but today it announced the successor to Hummingbird: Orion. Samsung's 45nm Orion SoC implements two Cortex A9 cores running at 1GHz, each with a 64KB L1 cache (32KB+32KB) and a large 1MB shared L2 cache. At 45nm peak power consumption should be greater than the Cortex A8 based Hummingbird, but average power consumption may be lower thanks to the improvement in IPC that accompanies the Cortex A9. 

The GPU specs are unusual. Samsung lists Orion as having up to 5x the GPU performance of its previous generation SoC (presumably Hummingbird). We just finished talking about how great Hummingbird's PowerVR SGX 540 is, but to outperform it by 5x would require a serious GPU. I'm not sure I believe Samsung's claim. It is interesting that 5x is the same number NVIDIA used in its announcement yesterday.

TI is also working on a Cortex A9 based SoC - the OMAP 4. Due to ship in Q4 2010 with devices available in 2011 the OMAP 4 series sounds a lot like Orion. However OMAP 4 will use the SGX 540, not whatever higher performing option Samsung turned to for Orion.

If you like you keep your smartphones for a while, it seems like now would be the worst time to buy. Within 6 months you should have much faster options at your disposal (Update: it's unclear when Orion will ship, but at least NVIDIA will have dual core A9 based products in the market by then).

iPhone 3G users have been unhappy, and rightfully so. When iOS 4.0 debuted, we talked about new features like multitasking for the iPhone 3GS and how much faster the camera application felt compared to iOS 3.1.3. iPhone 3G customers, however, gained little in terms of new features from the update except newfound slowness.

Discontent has been growing, with a number of users pointing fingers at Apple and citing planned obsolesnce as a possible motive. Steve Jobs later promised that iPhone 3G performance would improve, and that an update was coming to address speed on the aging platform.

Fast forward to September 1st, and the iPhone 3G slowdown is an official bug which will be be 'fixed' with iOS 4.1. We’ve gone hands on with the iOS 4.1 gold master and tested speed and general responsiveness thoroughly. What can iPhone 3G users expect? Read on for the full story.

After the ATI acquisition AMD announced it would be creating a new category of microprocessors that featured integrated ATI GPUs. AMD called these hybrid CPU/GPUs Accelerated Processing Units (APUs) and it branded the entire APU strategy: Fusion.

The first Fusion project we heard about was Llano for mainstream notebooks/desktops. Llano will integrate a 32nm derivative of the current Phenom II architecture with a relatively capable DirectX 11 AMD GPU. Llano isn't due out until sometime in 2011 so details are still light. However, AMD just released some details on its lower end Fusion APUs that will begin shipping in Q4 2010 (OEM system availability in Q1 2011).

Bobcat is the CPU core. Last month we went in depth on its architecture. In short, Bobcat is an out-of-order alternative to Intel's Atom that has the potential to offer significantly higher performance. But since we're talking about APUs, Bobcat is only a part of the equation.

AMD will be shipping two Bobcat based APUs in Q4: Ontario and Zacate. Both APUs implement two Bobcat cores and a DX11 AMD GPU with an undisclosed number of cores. Ontario is aimed at netbooks/nettops while Zacate can be used in ultra thins and value notebooks/desktops.

Today at IFA in Berlin AMD announced the Ontario and Zacate TDPs as well as shared a photo of a low power AMD Fusion APU (possibly Ontario?). The Ontario APU is rated at 9W, while Zacate is rated at 18W.

LG was one of the first companies to demonstrate a Moorestown based phone as recently as earlier this year. Just one hour ago however LG announced that starting in Q4 2010 it will be shipping smartphones based on NVIDIA's Tegra 2.

We first introduced you to Tegra 2 back at CES 2010. It's NVIDIA's second generation smartphone SoC with a pair of ARM Cortex A9 cores (ARM's first out-of-order architecture). The dual core CPU will run at 1GHz. Tegra 2 also features NVIDIA's own mobile GPU, although we know nothing of its architecture or how well it stacks up to high end GPUs from Imagination Technologies. NVIDIA calls it a GeForce GPU however I'd be surprised if there's any similarities between it and what's shipping in desktop GeForce GPUs today.

LG's press release is pretty light on details although we do get some performance projections. LG states that web browsing can be up to 2x faster and gaming performance can be up to 5x faster compared to single core processors running at 1GHz. If we're conservative and assume that is in comparison to Qualcomm's Snapdragon SoC then we'd expect Quake 3 frame rates at just under 100 fps. Web browsing at 2x the speed of Snapdragon would be much faster than anything we've seen to date.

LG mentions that Tegra 2 will enable 1080p HD video playback however with no indication of bitrate it's too early to get excited about that claim. TI's OMAP 4 will also have 1080p support when it ships in phones next year. The same is true for Intel's Moorestown based devices.

Obviously SoC speed isn't all that matters, LG has to deliver a compelling smartphone design. The first LG Tegra 2 smartphones will be a part of its Optimus Series of smartphones, most likely running Android.

This one has been a hotly requested item from you all: a review of the Samsung Galaxy S. Samsung sent us their newest Galaxy S phone, the Epic 4G for use on Sprint's WiMAX network. It's the first 4" phone we've reviewed, the first to use Samsung's Hummingbird SoC and the first with a Super AMOLED display.

The CPU performance proved to be on par with the Motorola Droid X and other 1GHz Android offerings, but the GPU performance is a good 30 - 45% better than anything else on the market today. The new Super AMOLED display is also a huge improvement over the AMOLED screens we've seen in other Android phones. 

Battery life leaves a lot to be desired as the Epic 4G lasted less than 4 hours in our 3G/4G web browsing tests. We also encountered issues with the phone's GPS receiver as many others have reported.

Overall Samsung's Epic 4G is a nice step forward for Android, but with a few glaring issues it remains imperfect.

Read about it all and more in our full review of the Epic 4G.

The Silent Pro series is one of the best-known series power supplies from Cooler Master, previously covering range from 500 to 700 watts. The range has now extended to 1000W with two models rated at 850W and 1000W, including flat connection cables found in higher power classes. Today we are looking at the latter. The 1000W model comes with a 5-year warranty, promises a maximum efficiency of 86%, and uses a single +12V rail. Excluding the motherboard connectors all cables are fully modular. Cooler Master also makes note of the high quality of selected components. Even though the housing of the PSU seems to be very similar to the smaller Silent Pro, a different ODM is responsible for the manufacture. On the next pages we will explore the design and topology and see if Cooler Master is able to keep their promises.

The pricetag of Lenovo's ThinkPad X100e has come down a couple of hundred dollars from its lofty perch when it entered the market more than six months ago, but it still remains a pricy alternative to CULV and Atom-based ultraportables. The X100e is saddled with AMD's outdated Congo platform, but is there more to a notebook than just the hardware under the hood? We think so, and we took the ThinkPad X100e for a spin to prove that the platform isn't always what counts.

When Fermi first launched on the desktop, we wondered how long it would take to trickle down to the lower end markets—and the mobile team also wondered if we'd ever see Fermi make it into notebooks. NVIDIA managed the latter with the GTX 480M, a lower clocked chip harvested from the full GF100. Now they're ready to launch the rest of their mobile lineup, with product schedule to start shipping later this month. Want to see what NVIDIA's brining to the table? We've got the official specs, though we do have to note that there are a few areas NVIDIA isn't discussing just yet. Regardless, we'll see plenty more Optimus Technology laptops and notebooks, and mobile GPUs may actually get the kick in the shorts we've been longing for!

Our Ask the Experts series continues with another round of questions.

A couple of months ago we ran a webcast with Intel Fellow, Rich Uhlig, VMware Chief Platform Architect, Rich Brunner and myself. The goal was to talk about the past, present and future of virtualization. In preparation for the webcast we solicited questions from all of you, unfortunately we only had an hour during the webcast to address them. Rich Uhlig from Intel, Rich Brunner from VMware and our own Johan de Gelas all agreed to answer some of your questions in a 6 part series we're calling Ask the Experts. Each week we'll showcase three questions you guys asked about virtualization and provide answers from our panel of three experts. These responses haven't been edited and come straight from the experts.

If you'd like to see your question answered here leave it in the comments. While we can't guarantee we'll get to everything, we'll try to pick a few from the comments to answer as the weeks go on.
