NVIDIA buys high-performance chip-maker Mellanox for $6.9 billion
NVIDIA confirmed that it has purchased Israeli chip-maker Mellanox for $6.9 billion, its largest acquisition to date. The bid, rumored for several days, trumped a $6 billion offer made by Intel several months ago. It will reportedly help NVIDIA better compete in the server market, which accounts for about a third of its sales.
IEEE pushes for Ethernet standard between 400Gbps and 1Tbps, hopes to head off big data crunch
Ethernet might seem passé to those of us toting Ultrabooks, but it's important enough to provoke a crisis for internet providers and many of those who depend on high-speed computing networks for a living: based on the rises of streaming video and social networking, the IEEE is worried that many of those large-scale networks will need 10Tbps of total bandwidth just to avoid a logjam in 2020. To that end, the standards body has formed a Higher-Speed Ethernet Consensus group that's mulling a new, breakneck-speed format reaching either 400Gbps or 1Tbps, depending on whose approach you'd favor. Fight the urge to pick the 1Tbps option on instinct, however. Both options would depend on bonding multiple connections together, and the faster of the two formats could lead to some expensive and very ungainly cables if it's not handled well. A meeting is scheduled for late September in Geneva to at least begin hashing out the details. Although we won't be wiring our homes with terabit Ethernet anytime soon, the standard should come quickly enough that the Googles and Netflixes of the world can satisfy our data addictions for a good while longer.

Intel slips details of Poulson-based Itanium 9500 in advance, teases a big boost to 64-bit servers
If you think Intel took awhile to roll out the Xeon E5, imagine the mindset of Itanium server operators -- they haven't had any kind of update to the IA-64 chip design since February 2010, and they're still waiting. Much to their relief, Intel just dropped a big hint that the next-generation, Poulson-based Itanium is getting close. Both a reference manual and a Product Change Notification have signaled that the new, 32-nanometer part will get the Itanium 9500 name as well as a heap of extra improvements that haven't been detailed until now. We knew of the eight processing cores, but the inadvertent revelation also confirms about a 50 percent hike in the interconnect speed and a matching increase in the cache size to 32MB. Clock speeds also start where current Tukwila-running Itaniums stop, with four processors between 1.73GHz and 2.53GHz giving the line a much-needed shot of adrenaline. Few of us end users will ever directly benefit when Poulson ships to company server farms later this year; after these increases, though, don't be shocked when the database at work is suddenly much quicker on its toes.
Core Values: What's next for NVIDIA?
Core Values is our new monthly column from Anand Shimpi, Editor-in-chief of AnandTech. With over a decade of experience poring over the latest in chip developments, he's here to explain how things work and why our tech is the way it is. I remember the day AMD announced it was going to acquire ATI. NVIDIA told me that its only competitor just threw in the towel. What a difference a few years can make. The last time NVIDIA was this late to a major DirectX transition was seven years ago, and the company just quietly confirmed we won't see its next-generation GPU, Fermi, until Q1 2010. If AMD's manufacturing partner TSMC weren't having such a terrible time making 40nm chips I'd say that AMD would be gobbling up marketshare like a fat kid. By the time NVIDIA gets its entire stack of DX11 hardware out the gate, AMD will be a quarter away from putting out newly refreshed GPUs. Things aren't much better on the chipset side either -- for all intents and purposes, the future of NVIDIA's chipset business in the PC space is dead. Not only has NVIDIA recently announced that it won't be pursuing any chipsets for Intel's Core i3, i5. or i7 processors until its various legal disputes with Intel are resolved, It doesn't really make sense to be a third-party chipset vendor anymore. Both AMD and Intel are more than capable of doing chipsets in-house, and the only form of differentiation comes from the integrated graphics core -- so why not just sell cheap discrete GPUs for OEMs to use alongside Intel chipsets instead? Even Ion is going to be short lived. NVIDIA's planning to mold an updated graphics chip into an updated chipset for the next-gen Atom processor, but Pine Trail brings the memory controller and graphics onto the CPU and leaves NVIDIA out in the cold once again. Let's see, no competitive GPUs, no future chipset business. This isn't looking good so far -- but the one thing I've learned from writing about these companies for the past 12 years is that the future's never as it seems. Chances are, NVIDIA's going to look a lot different in the future because of two things: Tesla and Tegra.
Intel boosts high-performance computing with new cables
Intel looks to have found a way to make high-performance computing (or HPC, as it's called) even more high-performance, today unveiling some new cables designed to give clustered systems a boost, along with a new "Intel Cluster Ready" initiative that's intended to ensure the various components all get along nicely. The cables, dubbed "Intel Connects," will work with Inifiband and 10 GbE-based systems, and promise to deliver speeds up to 20 Gbps over a distance of 100 meters. What's more, the cables also look to be quite a bit more manageable than those of the current variety, weighing 84% lighter, measuring 83% smaller, and boasting a 40% smaller bend radius. No word on when they'll actually be available though, so those of you running a render farm in your basement will have to put up with the current mess of cables for a little while longer.
