When Alienware announced the Ivy Bridge refresh for its gaming notebook lineup, one model was conspicuously absent. Word filtered out that the smallest member of the range, the 11.6” M11x, would not be refreshed and that Dell was preparing to discontinue the line. For ultramobile gamers, the loss of the M11x is a huge blow, because it was one of the more unique notebooks out there—a near ultraportable with legitimate gaming aspirations, backed up by gaming performance that lit the class standards on fire. It was a truly standout notebook, and it will be sorely missed.
But now, a spiritual successor emerges in the form of Clevo’s W110ER. We have this unit courtesy of Eurocom, who are calling it the Monster 1.0, but other boutiques selling the W110ER include AVADirect, OriginPC, Sager, and XoticPC amongst others. We typically see this with larger notebooks from Clevo and Compal, but it hasn’t been as prominent with smaller notebooks until now, with the exception of some ASUS models from years past.
The W110ER spec sheet actually reads like a pipe dream, something that you would come up with if things like thermal limits didn’t exist. The performance-class GPU is present and accounted for—Clevo ships every W110ER whitebook with a Kepler-based GT 650M (2GB DDR3, 384 CUDA cores, Optimus). But the most impressive thing here is that the W110ER has support for Intel’s new IVB 35W quad-core CPUs. Yeah seriously, a quad-core 11.6” notebook. Just to refresh your memory, the M11x made use of Intel’s low voltage dual-core parts, so this is a significant step up in CPU performance. It’s a ridiculous amount of performance stuffed into a tiny notebook. Interested? Read on.
While we were off at NVIDIA’s GTC 2012 conference seeing NVIDIA’s latest professional products, NVIDIA’s GeForce group was busy with some launches of their own. The company has quietly launched the GeForce GT 610, GT 620, and GT 630 into the retail market. Unfortunately these are not the Kepler GeForce cards you were probably looking for.

As NVIDIA was already reusing Fermi GPUs for GeForce 600 series parts for the OEM laptop and desktop market, it was only a matter of time until this came over to the retail market, and that’s exactly what has happened. The GT 610, GT 620, and GT 630 are all based on Fermi GPUs, and in fact 2 of them are straight-up rebadges of existing GeForce 400 and 500 series cards. Worse, they’re not even consistent with their OEM counterparts – the OEM GT 620 and GT 630 are based off of different chips and specs entirely.
At the bottom of the 600 series retail stack is the GeForce GT 610, which is a rebadge of the GT 520. This means it’s either a GF119 GPU or cut-down GF108 GPU featuring a meager 48 CUDA Cores and a 64bit memory bus, albeit with a low 29W TDP as a result. This is truly a rock bottom card meant to be a cheap as possible upgrade for older computers, as even an Ivy Bridge HD4000 iGPU should be able to handily surpass it.
The second card is the GT 620, which is a variant of the OEM-only GT 530. With 96 CUDA cores we’re not 100% sure that this is GF108 as opposed to the 28nm GK117, but as NVIDIA currently has a 28nm capacity bottleneck we can’t see them placing valuable 28nm chips in low-end retail cards. Furthermore the 49W TDP perfectly matches the GF108 based GT 530. Compared to the OEM GT 620 the retail model has twice as many CUDA cores, so it has twice as much shader performance on paper, but because of the 64bit memory bus it’s going to be significantly memory bandwidth starved.
The final new 600 series card is the GT 630, which is a rebadge of the GT 440. Like the GT 440 this card comes in two variants, a model with DDR3 and a model with GDDR5. Both models are based on GF108 and have all 96 CUDA cores enabled, and have the same core clock of 810MHz. At the same time this is going to be the card that deviates from its OEM counterpart the most. The OEM GT 630 was a Kepler GK107 card, so this rules out getting a Kepler based GT 630 retail card any time in the near future.
As always, rebadging doesn’t suddenly make a good card bad – or vice versa – but it’s disappointing to once again see this mess transition over to the retail market. We hold to our belief that previous generation products are perfectly acceptable as they were, and that the desire to have yearly product numbers in an industry that is approaching 2 year product cycles is silly at its best, and confusing at its worst.
OCZ has added a low profile version of the Vertex 3 to their SSD portfolio. The drive has a height of 7mm, which is 2.5mm slimmer than most 2.5" drives are. Other specifications match the regular Vertex 3, so reading our Vertex 3 review will give you an idea of the performance, but below is a specification table in case you don't remember the main details off hand:
| OCZ Vertex 3 Low Profile Specifications | ||||
| Capacity | 60GB | 120GB | 240GB | 480GB |
| Interface | SATA 6Gb/s | |||
| NAND | 2Xnm MLC | |||
| Number of NAND Packages | 8 | 16 | 16 | 16 |
| Number of Die per Package | 1 | 1 | 2 | 4 |
| Sequential Read | 535MB/s | 550MB/s | 550MB/s | 530MB/s |
| Sequential Write | 480MB/s | 500MB/s | 520MB/s | 450MB/s |
| Max 4K Random Write | 80K IOPS | 85K IOPS | 85K IOPS | 35K IOPS |
A Canadian retailer, Canada Computers, is already listing the low profile versions and pricing appears to be slightly higher compared to normal Vertex 3. However, Canada Computers has not received any stock yet so the prices may not be final yet. Availability is unknown as of now but expect to see these SSDs in stores within a week or two.
We are definitely experiencing a shift towards smaller form factors in storage devices and computing in general. Especially Intel's Ultrabook project is fuel for the fire because in order to meet Intel's strict dimension limitations, it's necessary to use either mSATA SSDs or thinner 2.5" SSDs/HDDs. On top of that, the internal components of SSDs don't usually even need the extra 2.5mm and making a drive 7mm instead of 9.5mm is only a matter of shaving off some of the chassis. I'll give you a sneak preview of our Plextor M3 Pro review to demonstrate this:
Plextor M3 – 9.5mm tall
Plextor M3 Pro – 7mm tall
Both SSDs have exactly the same PCBs and the only thing that makes the M3 Pro thinner is the fact that it has thinner thermal pads. What this means is that pretty much any 2.5" SSD could be turned into a 7mm model without even modifying the PCB.
I would like to see more hybrid approaches like what Intel is doing, though. Hybrid in this case means that there's a riser attached by screws that turns a 7mm SSD into a 9.5mm SSD. Some laptops are designed for 9.5mm drives and a 7mm drive might jiggle inside the laptop.
Example of the use of a riser
Having a riser means the user doesn't need to decide between 7mm and 9.5mm as you can easily remove the riser if you need to fit drive inside a computer that only takes 7mm drives. Of course, offering 7mm and 9.5mm drives like OCZ and Plextor are doing is better than offering only 9.5mm drives, but using a riser still looks like the best option.
We have already reviewed quite a few PC Power & Cooling products on AnandTech, but this time we will be looking at their first series with modular cables and a white case. In contrast to older PSUs PC Power & Cooling delivered, this one provides a 120mm fan for cooling as well. The new Silencer MK III models are available in 400, 500 and 600W only. This is a good news for everybody who is interested in small power supplies as they deliver more than enough power for any common PC with one graphics card.
PC Power & Cooling uses Japanese capacitors, one powerful +12V output, a ball bearing fan from ADDA , and a partially modular cable management. With 80 Plus Bronze certification, the Silencer MK III seems to be an average product, but Seasonic is the company behind these products—and they're definitely a good choice. What about the internal design and components? On the following pages we will see if they meet one's expectations.
The new Kepler GPU that Nvidia recently announced has been five years in the making.
It will be at the heart of supercomputers that will help make scientific discoveries as well as powering gaming clouds and high resolution remote computing. But why is Kepler more than just another really powerful, really expensive GPU?
If it was just really powerful, Kepler would still be impressive. Demonstrating a combination of fluid simulation and ray tracing, Nvidia CEO Jen-Hsun Huang pointed out that "Doing ray tracing for films takes up the vast majority of processing time – the hours and hours that are necessary to render a frame – and with Kepler we’re able to do ray tracing in real time.
"These are real time simulated effects that are only possible because of high performance computing only possible because were really doing fluid simulation, light simulation. Simulation and computer graphics are merging; in a few years computer graphics will look nothing like the easily shaded graphics we see in console games today."
Faster and lower power
Architecturally, Kepler is both faster than the previous Fermi GPU and lower power; there are many more cores but they run at 750MHz rather than 1.3GHz.
Two GPUs on a graphics card like the Kepler-powered GTX 690 will be able to communicate directly with each other; they can also communicate with up to 32 CPU cores instead of just one CPU at a time, and data parallelism means the GPU can look at the results of computations and decide what to do next instead of sending information back to the CPU and waiting for instructions.
It also has a memory management unit; combined with Nvidia’s hypervisor and VGX architecture, that lets Kepler be a virtual GPU for remote access with a tool like Citrix Receiver on a tablet or Microsoft RemoteFX on a thin client – or power gaming cloud services that Nvidia is calling GeForce Grid.
Not all of that is in the first Kepler GPU, the Tesla K10 that’s just started shipping, but all the features will be in the Tesla K20, coming in the fourth quarter of 2012.
Services like Playcast and Gaikai will use Kepler GPUs later this year to let you play console-style games on any device with an H.264 decoder. That’s similar to the OnLive service but Nvidia General Manager Phil Eisler says GeForce Grid will be much more efficient to run.
"With the first generation of cloud gaming that’s out there, you pretty much take a one to one ratio of one computer, one graphics card to one game, which is pretty expensive. The new Kepler architecture is much more power efficient; we can actually render a game in half the power.
"Plus the built in encoder means you can offload encoding from the CPU so you can run many more games per server; you can go from what is effectively one game per server to about eight games per server and that reduces the cost by that much and reduces power by half."
The cost of running a service will be low enough that Nvidia CEO Jen-Hsuan Huang told TechRadar the expects the monthly price for access to mainstream games will be the same as streaming films from Netflix. "Our goal is to be streaming at a cost level like Netflix. In which case you’ll be able to enjoy hundres of games, thousands of games in a library for a month. And for blockbuster video games the moment that it comes out, the nanosecond it comes out, you’ll be able to enjoy that for some premium charge."
Huang thinks that cable TV companies and Internet TV providers will offer their own gaming services. "They offer different channels and instead of ABC and CBS there would be potentially a channel that says GeForce GRID and has a whole bunch of games inside."
Kepler is going to power high resolution remote computing for work and high performance gaming in the cloud, but what about putting it in your home PC and having your own cloud? Huang likes the idea but he’s realistic about how well it would work in practice.
"The challenge is you want to be able to stream at a very low latency and that PC sitting in a den somewhere is literally right in front of you but we need to stream that over the clumsy Wi-Fi in people homes so there’s a lot of obstacles. That’s exactly the PC I want at home though. I want a PC with three GTX 690s – because that’s the most you can put in a PC- and put that in the basement somewhere and just stream it to wherever our family happens to be."
One thing Nvidia isn’t talking about this week is whether any of the same technology powering Kepler is going to show up in the ARM CPU it promised to build back at CES 2011, but Project Denver is still going strong according to Chief Scientist Bill Dally.
"It’s an ARM core with performance better than you can get with cores availability from ARM and it has substantially better energy efficiency even at this higher performance. That’s all we’re saying about it now, because we don’t want to tip our hand and have our competitors know what we’re doing."
Huang is making his usual bold predictions about Project Denver though; "You are going to be so happy," he promised. It doesn’t sound as if they’ll be ready for the Windows RT launch though.
