Old Intel chips are vulnerable to a fresh security exploit
If you have an old, Intel-based computer hanging around, you might want to get rid of it post-haste. Security researcher Chris Domas has discovered a vulnerability in the x86 architecture of Intel processors made between 1997 and 2010 (pre-Sandy Bridge) that lets an attacker install software in a chip's protected System Management Mode space, which governs firmware-level security. Yes, that's as bad as it sounds: an intruder could not only take more control than you typically see in attacks (including wiping firmware), but infect your PC even if you wipe your hard drive and reinstall your operating system. Domas has only tested against Intel-made CPUs so far, but AMD processors could be vulnerable as well.

Apple store goes down, iMac refresh on high alert
Details are spotty but Apple special forces have apparently swept into its data center, temporarily disrupting the company's ability to sell anything online. We're expecting official word of the operation from company CEO Steve Jobs, at about 08.30 Eastern Time. With any luck, a new iMac will emerge unscathed by the Nehalem menace, sporting a brand new Sandy Bridge microarchitecture -- or as we like to call it: freedom. [Thanks to everyone who sent this in]

Intel Core i7-990X stealthily hits shelves, Origin PC overclocks one to a lap-melting 4.6GHz
These days it's less about the megahertz and more about the cores, but custom PC maker Origin isn't leaving either benchmark untouched. It's taken the as-yet-unannounced six-core, 3.46GHz Intel Core i7-990X processor and pushed it up to 4.6GHz -- a full 200 hertz more than the company's previous hotness, a 4.4GHZ Core i7-980X. The 990X is now available in the company's desktops as well as the EON-17 laptop -- which is honestly pushing the boundaries of lapablity. Think you can do better than that -- say, with a little LN2? You'll find the Core i7-990X at the likes of Mwave and Newegg for what we're sure is a perfectly reasonable $1,050 right now. [Thanks, Travis]

Intel plans to stuff more than 8 cores, extra speed into 2011 server chips
Yeah yeah, "more cores and faster speeds," you've heard it all before right? That'd be our reaction too if we weren't talking about the successor to the Nehalem-Ex, Intel's most gruesomely overpowered chip to date. Launched under the Xeon 7500 branding in March, it represents Intel's single biggest generational leap so far, and with its eight cores, sixteen threads, and 24MB of shared onboard cache, you could probably see why. Time waits for no CPU though, and Intel's planned 32nm Westmere-Ex successor will move things forward with an unspecified increase in both core count (speculated to be jumping up to 12) and operating frequencies, while keeping within the same power envelope. Given the current 2.26GHz default speed and 2.66GHz Turbo Boost option of the 7500, that means we're probably looking at a 2.4GHz to 2.5GHz 12-core, hyper-threaded processor, scheduled to land at some point next year. Time to make some apps that can use all that parallel processing power, nay?

Intel readies 8-core Nehalem-Ex processors for a March launch
Intel's current generation of Xeon processors already represents some of the fastest silicon you can buy, and yet the company's forthcoming Nehalem-Ex-based Xeons are being touted as the single greatest generational jump in its history. To achieve that, Intel has strapped eight cores into each CPU, with a pair of threads per core and 24MB of shared cache, along with integrated quad-channel memory controllers, Turbo Boost, and the pretty awesome ability to scale up to eight sockets -- meaning you could have 64 processing cores in the same rig. Don't even ask whether these chips can run Crysis 2, they'll probably be showing up in the machines that are making the game... and maybe yours, provided you have the cash to splash later this month.

Mac Pro users reporting performance hit linked to audio use
Nehalem-based Mac Pro users are reporting in Apple's discussion forums and other locations that some audio tasks are causing performance issues. There is up to a 20% drop in performance while doing tasks as simple as listening to music in iTunes. Other users are saying there are similar issues when utilizing Logic and Flash. The issues are also causing internal temperatures to skyrocket. One forum user showed how playing a 4-minute track in iTunes caused the internal temperature of his Mac Pro to increase by 11 degrees. Several users have shown that booting into Windows 7 on the Mac Pro resolves these issues, pointing the finger at OS X as causing the problem. Forum members are saying that pleas to AppleCare are falling on deaf ears. A Facebook group is now tracking the problem, offering advice and performance test suggestions. [Via MacNN]

Intel's Arrandale and Clarkdale CPUs get benchmarked for your enjoyment
Whoa, Nelly! Just weeks after Intel came clean with its new Pine Trial nettop and netbook platform, the company is today cutting loose with a few more. This go 'round, we've got the 32nm Arrandale (which consists of the Core i5 Mobile and Core i3 Mobile) heading for the laptops and the 32nm Clarkdale chips over on the desktop front. Starting with the former, most reviews found the CPU + GPU solution to be faster than rivaling Core 2 Duo + integrated GPU options, with the Core i5 being particularly potent in highly threaded applications. Better still, battery life didn't seem to take a hit even with the extra performance, though high-end, high-res gaming was still a lesson in futility when working without a discrete graphics card. Overall, the chip was a welcome addition to the fold, but we got the feeling that the first wave was priced too high and offered too little of a performance increase on the gaming side to really warrant a wholehearted recommendation. As for the Clarkdale? The Core i5 661 that everyone seemed to snag was found to be blisteringly fast, with most folks deeming it the outright champion in the dual-core realm. Unfortunately, the integrated GPU was -- again -- not awesome for hardcore gaming, and the questionable pricing didn't exactly thrill some critics. Do yourself a favor and dig into the benchmarks below -- we get the feeling we'll be seeing oodles of machines hit the wires this week with these chips within.

Mac Pro gets a speed bump, Xserve has new storage options
After the introduction of the new 27" Intel Core i7 iMac in October, a lot of us in the Mac world were puzzled by the lack of a new higher-end Mac Pro. After all, the Mac Pro has traditionally been the most powerful Mac with the highest level of expandability. This morning, Apple quietly announced a speed bump for the Mac Pro, as well as new storage options for both the Mac Pro and the Xserve. For the quad-core Mac Pro (but not the eight-core model), you can now order a 3.33 GHz Quad-Core Intel Xeon "Nehalem" processor. This is an amazing CPU, with 8 MB of fully shared L3 cache, Hyper-Threading technology, an integrated memory controller, and Turbo Boost for short bursts of speed up to 3.6 GHz. Now that prices have come down a bit on 2 TB hard drives, Apple has made them a configure-to-order option for Mac Pro and Xserve systems. Using high-performance 7200 RPM SATA drives with 32 MB of cache and a potential throughput of 3 Gb/s, the Mac Pro can now have a total storage capacity of 8 TB, while the Xserve can max out at 6 TB of storage. The new options are available immediately from the online Apple Store.

Rumor: MacBook Pro Intel Arrandale processors in January
Fudzilla is reporting that Intel will release Arrandale-based processors on January 3rd, 2010. Three in fact, branded as "Core i5" and "Core i7," ranging in speed from 2.4GHz to 2.66GHz. There are two Core i5 models. One features 3MB of cache, a 2.4GHz frequency, two cores and four threads plus Turbo Mode, while the other features two cores, four threads, Turbo Mode, 3MB of L2 cache and a 2.53GHz frequency. Fudzilla prices them at $225US and $257, respectively. Finally, the 2.66GHz Core i7 model features 4MB of cache and Turbo Mode and can run faster. Fudzilla expects them to sell for $332. You'll remember that desktop Macs received Nehalem architecture processors earlier this year, which these Arrandale processors are based on. If built into Apple's MacBook Pros, they'd represent a significant performance boost over the Core 2 Duo processors currently in use. [Via MacRumors]

NVIDIA halting chipset development after all
It's been about two months since NVIDIA called rumors that it was leaving the chipset business "groundless," so perhaps it's no big shock that PC Magazine is now reporting that the company is putting its nForce chipset line "on hiatus." On hiatus, that is, until the company gets a few sticky legal questions out of the way, including whether or not its four-year deal with Intel covers Core i7 processors. Thus we have the delicate line that NVIDIA walks with Intel: for the time being, the two companies need each other, but they don't have to like each other, and as the latter continues to pursue graphics integration with the CPU, manufacturers are going to be increasingly pushed towards all-Intel solutions. All this leads us to wonder if NVIDIA might decide chipsets in general are more trouble than they're worth, especially considering Intel's general attitude about them -- and whether ION might be the next on the block.Update: We've just received an email from NVIDIA's Ken Brown that sheds a little light on the matter. It reads, in part: "[B]ecause of Intel's improper claims to customers and the market that we aren't licensed to the new DMI bus and its unfair business tactics, it is effectively impossible for us to market chipsets for future CPUs. So, until we resolve this matter in court next year, we'll postpone further chipset investments for Intel DMI CPUs." Fair enough. Peep it for yourself after the break.

Intel announces quad-core Core i7 Extreme and Core i7 for laptops (update: now with reviews!)
As expected, Intel just announced its Clarksfield laptop chips, bringing Core i7 to the laptop form factor. There'll be three chips, two regular quad-cores and a Core i7 Extreme that can run as fast as 3.2GHz in Turbo mode, which selectively shuts off cores and uses the extra power to speed up the remaining cores while preserving battery life. The parts were demoed working in shipping-ready form on stage, but pricing and availability weren't mentioned -- we'll let you know what we can dig up.Read - Intel's Core i7 Mobile press releaseRead - HotHardware's Core i7 Mobile reviewRead - LegitReviews' Core i7 Mobile reviewRead - Laptop Mag's Core i7 Mobile laptop review

Intel Core i5 750 reportedly arriving September 6, bringing Core i7 friends
Presumably, Intel has been holding back its Core i5 CPUs in an effort not to cannibalize the prodigious success of its Core 2 line, but the chips had to come out of the oven at some point. If Chinese sources are to be believed, that time could be early this September. As detailed above, the i5 mainstream offerings will start at 2.66GHz (Core i5-750), alongside two additions to the Core i7 family, the 860 (2.8GHz) and 870 (2.93GHz). The new parts are highlighted by 8MB of cache and Turbo Boost -- Intel's auto-overclocking system that speeds things up when your cooling allows it. Click through for another slide detailing Clarkdale plans for 2010, which seem to agree with earlier rumors on the subject. Mmm, fresh silicon.[Via Slashgear]

Intel's Core i7 'Clarksfield' CPUs for laptops launching late September?
Taiwanese rumor-rag, DigiTimes, has a knack for sniffing out insider information from within Taiwan's MoBo manufacturing cartel. So it's worth paying attention when it claims to have the latest launch schedule for Intel CPUs. Up first is a trio of laptop-based Clarksfield CPUs -- 2GHz Core 2 Extreme XE, 1.73GHz Core 2 Quad P2, and a 1.6GHz Core 2 Quad P1 –- ready to make their debut sometime around the end of September or October. These processors should carry the Core i7 brand to keep things as confusing simple as possible and would be a suitable match for a Q4 refresh of the MacBook Pro or Dell XPS laptop, for example. At the low end of the rumored schedule are a pair of Celeron SU2300 and Celeron 743 CPUs for ultra-thin laptops with an expected announcement coming at the end of September. Intel's also pegged with plans for desktop-based Lynnfield CPUs and P55 chipsets to be announced between September 8-11. The first announcement is set for early August -- if Intel starts making a fuss about its new Xeon procs for servers at that time then we'll have a pretty good idea as to the validity of DigiTimes' claims.

Six-core Intel Nehalem processors in the works?
It's a bit of a whisper on the wind, but bit-tech says Intel's got six-core Nehalem processors in the works for later this year. The chips are said to be compatible with existing Nehalem mobos, so you crazy builders out there will be able to just drop it in and go. If you've got the scratch, of course -- pricing hasn't been revealed, but we'd expect the new part to be more expensive than the quad-core Core i7 975, which runs about a grand.[Via TrustedReviews]

Intel's new Nehalem-EX CPUs rock servers with eight cores, 16 threads, infinite sex appeal
What's that, you have an array of six-core CPUs in your rack? That is so last year. You're going to feel pretty foolish when all the cool admins start popping eight-core chips up in their closets this fall. That's the number on offer in Intel's latest, the Nehalem-EX. It's an evolution of the architecture that some of you may be spinning in your Core i7 machines, but boosted to support up to 16 threads and 24MB of cache. 2.3 billion transistors make the magic happen here, and Intel is pledging a nine-times improvement in memory bandwidth over the Xeon 7400. Chips are set to start hitting sockets sometime later this year, and while nobody's talking prices, staying hip in the enterprise server CPU crowd doesn't come cheap.

How would you change Apple's Nehalem-based Mac Pro?
Apple's freshest Mac Pro, which was the first machine of any kind to ship with Intel's newest Nehalem-based Xeon processors, has been on the block for a few months now. By our estimation, that's plenty of time for the pros (and "prosumers," if you will) to get a good feel of their new workstation. Design wise, not a lot has changed in the machine, but we're anxious to know how you feel about the more subtle changes as well as the internal overhauling. Apple's charging a small fortune for this bad boy, so we fully expect you to be critical here. What's it missing? What should've been included? Are you still bitter that WiFi is a $50 option on a multi-thousand dollar machine? Sound off below!

Xserve gets a performance boost
Astute readers noticed some Apple store downtime earlier this morning. While I was hoping for something soaked in Unicorn tears, I guess I'll settle for a drool-worthy Xserve update. The rumors were right on target, and the new Xserve sports Intel's "Nehalem" Xeon processor (just like the recent Mac Pro refresh), which Apple is touting as offering "twice the performance" when compared to last year's model.* * There is always an asterisk in these types of comparison so please read the fine print before taking any marketing slogans as gospel. The new Xserve systems look really hot. Check out these specs for the $2999US base model: a single 2.26 GHz Quad-Core Xeon 5500 series processor with 8MB of fully shared L3 cache 3GB of 1066 MHz DDR3 ECC RAM a single 160GB 7200 rpm SATA Apple Drive Module dual Gigabit Ethernet on-board two PCI Express 2.0 x16 expansion slots NVIDIA GeForce GT 120 256 MB with Mini DisplayPort output two FireWire® 800 and three USB 2.0 ports And of course, the requisite unlimited client license for Mac OS X Server version 10.5 Leopard. If the standard offerings aren't powerful enough, the Xserve can be customized to include two Quad-Core Xeon's running at 2.26, 2.66 or 2.93 GHz. An 8-core 2.26 Xserve configure like the base system runs $3599US. The new Xserve also offers an optional 128-GB SSD boot drive, as well as options for RAID cards, and dual or quad channel 4Gb Fibre channel cards. This generation of chipsets is more energy efficient and Apple is touting the newest Xserve as the "greenest ever." The new Xserve is available now at Apple.com and at your local Apple store or authorized dealer.

Intel's Xeon 3500, 5500 series officially unveiled for servers and workstations
Intel's announced this week its latest batch of Nehalem-based Xeon processors, the single-socket 3500 and dual-socket 5500 series for servers and workstations. Both models boast speeds up to 3.2 GHz and feature Intel's turbo boost, hyper-threading, and virtualization technologies, as well as integrated power gates. If you've got the newest Mac Pro, however, then you're already using the new quad-core CPUs,, but for everyone else, they're now being sold en masse to manufacturers at a price ranging from $188 to $1,600 for the Xeon 5500 and $284 to $999 for the 3500. We've already heard about 5500 / 3500-equipped Lenovo and Dell workstations, but if that doesn't suit you, Intel promises over 230 systems are in the pipeline from companies such as Cisco, Fujitsu, HP, IBM, among others.
Ross Miller03.30.2009NVIDIA sues Intel right back over Nehalem chipset licensing
Looks like the NVIDIA and Intel's lawsuit over Nehalem chipset licensing is heating up -- NVIDIA's filed a countersuit seeking to terminate Intel's licenses to its patents. This little bit of nyah-nyah is just the latest in the recent feud between these two: we've got a month-long argument about Atom chips and NVIDIA's Ion netbook platform going on, and don't even get anyone started on whether GPUs or CPUs are the wave of the future, it's freaking endless. Of course, this will all likely end in a settlement agreement and the these two realizing that they're actually in love, but until then we're just going have to put up with it. Video after the break.
