If you could get twice the performance for only a 50% increase, would you be willing to fork over the extra money? Compared to Atom, Intel's current CULV products offer exactly that, albeit with slightly less battery life. We have three representative models to look at today, and after seeing what CULV offers, you might think twice about buying that new Atom netbook....

Update: NVIDIA has confirmed that the Twitter account is indeed theirs, so this information is official.
With a skeptical eye towards Twitter, a post was made on the NVIDIAGeForce account 4 hours ago announcing the names of the first two GF100 cards. As we’re largely sure this is a legitimate NVIDIA account we’re going to go ahead and post this information, but please keep in mind that we have not yet been able to confirm that this is indeed an official NVIDIA posting (it’s 10PM on the West Coast).
With that out of the way, the post reads as follows:
Fun Fact of the Week: GeForce GTX 480 and GeForce GTX 470 will be the names of the first two GPUs shipped based on our new GF100 chip!
It’s a very small piece of information so we don’t have a lot of commentary here, but the names are a little bit surprising. The names are consistent with NVIDIA’s G/GT/GTX naming scheme, but we’re not quite sure what happened with the numbers. Technically speaking NVIDIA launched their 300 series late last year with the GeForce 310, an OEM-only rebadge of the GeForce 210. But we had expected that NVIDIA would fill the rest of the 300 series with GF100 and...

AMD’s often perilous financial situation usually bears watching, but this past quarter is of particular interest. On the business side we have seen AMD and Intel settle their long-standing feud over accusations of anti-competitive behavior by Intel, which had several big outcomes for AMD this past quarter. As part of the settlement terms Intel paid AMD a cool 1.25 billion USD, officially to make up for past transgressions – and unofficially as life support for a company that lost money for the last 13 quarters.
On the technology side we’ve seen AMD’s graphics division spend an entire quarter driving their own destiny. With Fermi/GF100 delayed well in to Q1 of this year, Q4 was all about the Radeon 5000 series – and it would have been an even better quarter if only it weren’t for that pesky TSMC 40nm supply problem. AMD’s CPU division didn’t have quite as rosy of a time, but Intel’s price gaps below $200 have left AMD with a viable value market.
So with that in mind, how did AMD fare for the quarter and for the year? It’s a mixed bag, particularly if you throw out the Intel settlement. Perhaps a table will best get at...
I've been using Dish Network for quite a few years now. Recently, I went through a forced upgrade to their latest ViP 722 high definition DVR. (I say "forced" because the older ViP 622 I had died, and Dish no longer supported the older unit. I didn't have to extend my contract, though.)
I haven't paid a great deal of attention to how rapidly IPTV services have been coming to the living room, built into consumer electronics devices. I've certainly used Hulu, plus the dedicated streaming services from individual "legacy" networks -- NBC and the like. I've also watched shows on Revision 3 and others of the new generation of Internet-only video.
About the only regular IPTV viewing we do here at the Case House as a family is the Netflix Watch Instantly service through the Xbox 360. Overall, that's been a pretty positive experience. We did have a couple of burbs, however. A few months ago, we transitioned from Comcast consumer broadband to Comcast Business. I mostly wanted faster upstream bandwidth, but we also encountered the dreaded bandwidth cap when using the Consumer service. What happened when we hit the cap was watching videos through Netflix in highly...
From our Radeon HD 5770 Review:
Interestingly enough, we’ve been told that the Phoenix shroud isn’t going to be sticking around for long. The first wave of cards launching today and for the near future will be using the shroud, but once AMD’s vendors begin using their own designs, AMD doesn’t expect most of the vendors to stick with the shroud. XFX has specifically been named as a party that will keep using the shroud on products, but anyone else is subject to change. With a TDP of only 108W, the Phoenix shroud is probably overbuilt and certainly more expensive than vendors would like, where mainstream products come with thinner margins. We would expect the vendors that do switch to move to more traditional dual-slot coolers, likely ones that aren’t shrouded at all and would not blow hot air outside of the case.
What AMD explained to us quickly came to pass, and once the first wave of 5770s sold out, the replacement waves started coming with coolers besides the Phoenix shroud. Since then we’ve had a number of people ask us how the later coolers compare to the Phoenix, and this is something that we can finally answer today.

Cloud Computing was probably the most popular buzzword of 2009. There was a lot of hype, but basically, cloud computing is about using the large datacenters of the Internet to your advantage. Either by copying the methods they use to be very scalable and available and applying them in your own datacenter (what VMware is partly trying to do with their "private Cloud", "vCloud"), by outsourcing your infrastructure (PaaS, SaaS) to an external datacenter via the Internet or most likely some hybrid form.
In 2010, all the hype and buzz should materialize. Will you use a form of cloud computing?

On a quick note this morning, along with yesterday’s release of the Catalyst 9.12 drivers, AMD has also published a 9.12 hotfix driver that has added a couple of interesting things.
Along with refreshing their line of OpenCL-capable drivers (OpenCL is still not in the mainline driver), AMD has added support for Crossfire Eyefinity. We first saw Crossfire Eyefinity in our Radeon 5970 review, where the feature was enabled solely for the 5970 so that the complete card could be used for Eyefinity. At the time AMD had promised that they would be enabling Crossfire Eyefinity for true Crossfire-paired cards soon, and this is the first step of fulfilling that promise. The need for AMD to whitelist games for Crossfire Eyefinity has not changed, so while it works on Crossfire-paired cards, it still does not work for all games.
The second interesting addition is support for DisplayPort audio. Although we tend to think of DisplayPort as a replacement for DVI rather than HDMI, technically it can serve as a replacement for both. Several of you have been asking us if the 5000 series supported DisplayPort Audio, and we did not have a good answer until now. If you do have a DisplayPort...

As promised for a long time, we've been working on pitting Xen and OpenVZ against eachother in a little "battle of the free virtualization solutions". (If you can't quite recall what this OpenVZ business is all about, we suggest you go read our article on container-based virtualization)
Though development of our vApus FOS benchmark suite is moving on quite diligently, it takes time to create both a realistic testing setup that will prove useful and relevant for a while in a world where cores are multiplying like a pair of rabbits. As it turns out, our test client is up for a thorough rewrite and optimization as well in the face of the upcoming Magny-Cours and 64-core Nehalem systems, so we definitely have our work cut out for us.
In preparation for the "official" rollout of vApus FOS, we have been using our beta versions to test both the performances of CentOS 5.4 Xen and OpenVZ, meanwhile figuring out just how easy it is to set up a large scale realistic testing environment in OpenVZ.
As with many extensive open source software packages, OpenVZ comes with quite a few hefty man-pages and very minimal basic configuration, making the learning curve quite...

Agner Fog, a Danish expert in software optimization is making a plea for an open and standarized procedure for x86 instruction set extensions. Af first sight, this may seem a discussion that does not concern most of us. After all, the poor souls that have to program the insanely complex x86 compilers will take care of the complete chaos called "the x86 ISA", right? Why should the average the developer, system administrator or hardware enthusiast care?
Agner goes in great detail why the incompatible SSE-x.x additions and other ISA extensions were and are a pretty bad idea, but let me summarize it in a few quotes:
"The total number of x86 instructions is well above one thousand" (!!)
"CPU dispatching ... makes the code bigger, and it is so costly in terms of development time and maintenance costs that it is almost never done in a way that adequately optimizes for all brands of CPUs."
"the decoding of instructions can be a serious bottleneck, and it becomes worse the more complicated the instruction codes are"
The costs of supporting obsolete instructions is not negligible. You need large execution units to support a large number of instructions. This means more...
We just got off the phone with Nick Knupffer of Intel, who confirmed something that has long been speculated upon: the fate of Larrabee. As of today, the first Larrabee chip’s retail release has been canceled. This means that Intel will not be releasing a Larrabee video card or a Larrabee HPC/GPGPU compute part.
The Larrabee project itself has not been canceled however, and Intel is still hard at work developing their first entirely in-house discrete GPU. The first Larrabee chip (which for lack of an official name, we’re going to be calling Larrabee Prime) will be used for the R&D of future Larrabee chips in the form of development kits for internal and external use.
The big question of course is “why?” Officially, the reason why Larrabee Prime was scrubbed was that both the hardware and the software were behind schedule. Intel has left the finer details up to speculation in true Intel fashion, but it has been widely rumored in the last few months that Larrabee Prime has not been performing as well as Intel had been expecting it to, which is consistent with the chip being behind schedule.
Bear in mind that Larrabee Prime’s launch was...
Raja and I have been working on a Holiday Guide the past couple of weeks and hopefully we will complete it this week. Our emphasis has been on finding components that offer a great bang for the buck even though they might not be the absolute best in their class. While we will offer our opinions on what is best in class, our focus has been on balanced performance, support, and features versus cost. A really good example is the ASRock X58 and P55 Extreme boards that offer a great set of features and performance for excellent pricing in each category. While they will not satisfy the needs of extreme overclockers, for the other 98% of us, they offer a really great value. Just like the Gigabyte GA-EP45-UD3P, MSI 790FX-GD70, and ASUS M4A77TD Pro have in their respective categories.
That said, there are a lot of great choices currently in the lower end market, especially in the AMD 785G camp. The 785G boards are just terrific values for building a SOHO centric platform that will be primarily used for office applications, Internet, communications, and casual gaming. This is especially true when paired up with an Athlon II based processor. Really, current Intel S775 processors in the sub $100...
In our Radeon HD 5970 review, we ran in to some issues when trying to overclock the card to 5870 speeds of 850MHz/1200MHz. At the time this is something we attributed to the VRMs, meanwhile AMD suggested that it was cooling related, and that we should manually increase the fan speed.
As it turns out, we were both right, we just didn’t have the tools at the time to properly identify and isolate the issue. Late last week we got our hands on a beta version of Everest Ultimate, which added preliminary support for the 5970. With that, we could read and log the voltages and temperatures of the various components of the 5970, and properly isolate the issue.
From that, we’ve discovered a few interesting things about the 5970. Let’s start things off with the cooler removed from the 5970.
We’ve gone ahead and circled the VRMs in red. There are 9 altogether; 6 on the right side, and 3 near the left side of the card. We aren’t able to track down what each specific VRM is connected to, but we believe that each GPU is attached to 3, each GPU’s RAM is attached to 1, and finally the PLX PCIe bridge is attached to 1. Regardless, pay attention to the location of these...
