Video: AMD's Phenom II X4 TWKR CPU for extreme overclocking lunatics
AMD has recently cooked up a little something they like to call the Phenom II X4 TWKR Black Edition, a hand-picked, limited edition processor that is designed to be overclocked "to the extreme." Currently labeled "Not for Sale," with no serial numbers and only one hundred of these bad boys in existence, just a few lucky folks have got their hands on one, so we've dug up some reviews (and previews) so you can see what the fuss is all about. According to the company, one of these guys could be pushed by 100MHz with air cooling, which doubles to about 200MHz with "extreme cooling." As far as impressions go, the reviewer at Neoseeker quickly decided that the units aren't meant to be overclocked on air only, and that dry ice isn't much better. Hot Hardware says pretty much the same thing. Though they weren't able to test with liquid nitrogen or liquid helium (the only way to get real speed) they did put a Koolance LN2 pot (and about 20lbs of dry ice) to the test for 4.73GHz. For best results, according to Tom's Hardware Guide, bench the processor at -190°C or cooler. But for the real overclocking experience you simply must check out the video of the "world renowned overclockers" K|ngp|n, chew*, and Gomeler as they run the gamut of "extreme overclocking techniques" after the break.

AMD debuts Athlon II X2 250 and Phenom II X2 550 Black Edition CPUs
If you're AMD, you've got to be feeling pretty good right now. Intel's busy handling a lawsuit bigger than the left half of Russia, you're finally free of that dreaded manufacturing business and you've got a new pair of mainstream CPUs debuting at Computex. The first of the two is the dual-core 45nm Athlon II X2 250, which features a TDP of 65-watts and can whittle power consumption down to 50 percent when handling just "basic tasks." Then there's the first-ever dual-core AMD Phenom II, the X2 550 Black Edition. Built from the ground-up for its 'Dragon' platform, this here chip also supports OverDrive 3.0 and should provide some higher-end features on a budget. Unfortunately, details beyond that are inexplicably scant, but we'll be sure to pass on whatever surfaces at the show. Full release is after the break.Read - HotHardware reviewRead - AMDZone reviewRead - OverclockersClub reviewRead - PC Perspective reviewRead - LostCircuits reviewRead - BenchmarkReviews reviewRead - TechSpot reviewRead - X-bit Labs reviewRead - Legion Hardware review
Liquid helium trumps liquid nitrogen at AMD's Phenom II overclocking love-in
Remember late last year, when AMD poured out the liquid nitrogen to boost its new Phenom II X4 to a ridiculous 5GHZ? The company's factory overclockers apparently had a lot of leftover LN2, so they invited a crew of others to come over and splash some around on a set of new Phenom II X4 955 Black processors. After burning through a ridiculous 80 gallons of the stuff they rolled out the even colder liquid helium, which led to a maximum benchmark of 6.89GHz -- more than twice the quad-core processor's 3.2GHz rated speed. In these tough economic times it's good to see that one company at least is still willing to take things to great excesses at the expense of Earth's natural resources.
AMD Phenom II X4 955 and 945 benchmarked to high heaven
Just when you though you'd had your fill of insanely detailed benchmarks of processors you may or may not have ever heard of, AMD's new Phenom II X4 955 and 945 hit the scene to get those overclockers all in a tizzy. The top of the line is the 955 "Black Edition" at 3.2GHz, while the 945 plays with a petty 3GHz. And the verdict? They're clearly AMD's fastest so far, but that might not be fast enough. AMD offers great value, but only really matches Intel's Core 2 offerings on performance -- Core i7 is still out in front. There is the fact that Phenom II offers a nice upgrade path for certain people who already do the AMD thing and are looking to upgrade, along with "enthusiasts" who are "enthused" by easy-access overclocking, but overall it looks like AMD is still playing catch-up with Intel.Read - HotHardwareRead - NeoseekerRead - PC PerspectiveRead - Tech ReportRead - TechSpotRead - EXTREME Overclocking
Dell's Phenom II-equipped XPS 625 benchmarked to the hilt
Yeah, we already heard that Dell's Phenom II-equipped XPS 625 was a solid value, but what does that really mean? The testing fiends over at HotHardware sought to find out, and after putting this gaming beast through more tests than it ever wanted to endure, they mirrored most of the earlier (positive) sentiments. In fact, it was found to boast one of the best price-to-performance ratios out there, and the "minimalist" software installation definitely earned brownie points in our book. One thing that bothered critics, however, was the excessive amount of noise. We too have noticed that Dell's ginormous XPS towers -- which, by the way, reviewers also found to be unnecessarily heavy and unwieldy -- can emit some serious decibels under heavy loads, but you'd think the engineers in Round Rock would've figured out a solution by now. Still, those quirks are probably small hassles to deal with given the savings compared to similar rigs, but we'd highly recommend digging into the read link just to be sure.
AMD's triple-core Phenom II X3 goes quad-core via BIOS hack
Here's a little known secret for you to chew on: that triple-core AMD Phenom II X3 you purchased actually has four cores. The last one's just locked down for pricing purposes. A Korean site has disclosed information that enables owners of select motherboards to unlock that fourth core, and apparently, all you need is a Biostar mobo and / or a BIOS that has an option labeled Advanced Clock Calibration. When said selection is flipped to "Auto," the fourth core is loosed from its shackles and able to ever-so-slightly up your frame rates and overall level of excitement. Of course, you're taking a big risk by running a chip in a fashion it was never intended, but what fun is life without a little edge-side living?[Via Slashgear]
IBuyPower dishes Dragon-based gaming desktops under $1,500
Yet again, IBuyPower is stepping out with a few new gaming rigs for the bargain-minded among us. The most recent duo to be outed by the company is the Gamer HAF 91B and the Gamer Fire, both of which are based on AMD's latest Dragon platform and Phenom II CPU. The former gets going at just $999 and includes the Phenom II X4 920 processor, 4GB of DDR2 RAM, a 500GB SATA II hard drive, a dual-layer DVD writer, ATI's 512MB Radeon HD 4850 graphics card, a CoolerMaster HAS 932 case and a 550-watt power supply. The more fiery sibling ups the ante with a Phenom II X4 940 CPU, a 750GB HDD, LG GGC-H20L Blu-ray drive and an NZXT Guardian 921 chassis. 'Course, you'll be paying $1,439 for that one, but either way you'll be keeping things below the evidently magical $1.5k mark. Order away, should you be so inclined. Full release is after the jump.
AMD ushers in five new Phenom II CPUs, benchmarking ensues
Just a month after AMD launched its Phenom II CPUs and Dragon desktop platform, the chip maker is hitting back with five new processors in the quickly expanding line. The newcomers include the planet's first 45nm triple-core CPU and three more quad-core siblings, all of which can operate in either AM2+ or AM3 sockets. As for performance? We hope your expectations haven't been set too high, as the chips were generally found to be just "a logical extension of [the company's] piecemeal upgrade plan and a fill in [the] gap to its lineup." Reviewers across the web were generally pleased but underwhelmed by test results, with HotHardware noting that "overall, Intel still has the performance edge clock-for-clock and core-for-core." In fairness, these chips were found to be good for overclocking, and for the right price, we could certainly see a few gamers giving them a go. For the full spill, dive on into the deep, intricate reviews below.Read - Official AMD announcementRead - HotHardware benchmarksRead - PCPerspective benchmarksRead - DesktopReview's review
AMD's Phenom II pushed to 6.5GHz, 3DMark record demolished
Ha, and you thought a 3DMark06 score of 5,086 was intense when AMD's Phenom II was overclocked to a blistering 3.85GHz. Just after CES, a team of hardcore speed freaks with access to liquid nitrogen and liquid helium created an environment for OC'ing one of AMD's latest Phenom II X4 chips in -232 degrees Celsius weather. Once the silicon was appropriately chilled, they proceeded to push the clock speed to a staggering 6.5GHz, which proved nimble enough to deliver a patently absurd 45,474 3DMark05 score. The best part? The adoring public was there to bear witness, and every nail-biting second of it is hosted up in the video just past the break.[Via Digg]
Dell's XPS 625 reviewed already, found worthy
We're well into the throes of CES and things are happening hot and heavy; Dell's Phenom II-packing XPS 625, announced just hours ago, has already been given a full once-over by DesktopReview.com, finding it to be a solid machine -- and even a good value. (When's the last time you read that conclusion about a gaming rig?) The review admires the machine's sophisticated looks, well-designed case, and easy expandability, but found that AMD's latest couldn't quite keep up with the i7 (as we'd heard earlier). Given the price point here that shouldn't exactly be a surprise.[Thanks, Patrick]
AMD talks up mildly ambiguous graphics supercomputer
It's not entirely clear what the purpose of AMD's newest supercomputer is, but it's pretty safe to say that the company is making it out to be something better than it is. All harshness aside, the so-called Fusion Render Cloud will reportedly be the planet's fastest graphics supercomputer. It sounds like the machine will be good for farming out tasks, and more specifically, for "real-time rendering of film and visual effects graphics on an unprecedented scale." Evidently AMD's hoping that gaming firms tap into the beast in order to develop and deploy next-generation game content, so that probably means it's worthless for you. But hey, it sounds awesome, right?
AMD finally launches Phenom II and its Dragon desktop platform
It was a struggle getting it "officially" out the door, and the reviews are already lackluster, but AMD's 45nm, quad-core Phenom II has finally arrived. It's available in two flavors, the 2.8GHz X4 920 and the 3.0GHz X4 940 Black Edition, going for $235 and $275, respectively. AMD's naturally touting the ostensible cost savings of the chips -- they're supposed to split the difference between Intel's Core 2 Quad and Core i7 processor -- but in reality they seems to trail Intel's offerings pretty soundly on the price / performance curve. The accompanying Dragon platform includes a Phenom II proc, 4800-series Radeon HD graphics and a 790-series motherboard, all of which should combine for low power consumption -- up to 40 percent compared to Phenom processors. Where the Phenom II definitely wins is the fact that some AMD folks will be able to drop in the chip to existing motherboards, but otherwise it looks like value hounds and performance junkies aren't being served by this new chip -- at least until unreasonable overclocking activities make all the pain go away.Read - AMD PRRead - PC World reviewRead - HotHardware review
AMD's Phenom II CPU goes on sale online in a curious, quiet fashion
Uh, AMD? We know most of your staffers are probably throwing back a glass of Egg Nog right about now, but you might want to get out something akin to a simple press release acknowledging the release of your dual-core Phenom II processor. For those keeping track, we've now seen the CPU announced via an outlet other than AMD, purchased by a normal citizen without access to AMD's labs and now, for sale on the world wide web. Word has it that the units will start shipping on December 27th, which will probably be prior to an actual confession of their existence in the retail channel by AMD. Not that we're complaining about the distinctly different than usual approach here, but our heads are certainly spinning.[Via PC World]
AMD Phenom II processor bought, benchmarked, coveted
AMD, a company not exactly known for meeting its own deadlines, seemed to be trying to avoid news of painful delays for the Phenom II by simply not letting anyone say when the thing would be available. Now the chip is apparently in the hands of one lucky gamer at the HardOCP forums, Table21, who was kind enough to run it through its paces. The Phenom II 940 running at 3GHz scored a 4,091 on 3DMark06 and, once OC'd up to 3.85GHz, delivered a score of 5,086. It's rather too early to draw any conclusions from these numbers, and we don't know what he paid for the thing, but that performance does fall well behind Intel's Core i7 Extreme that was similarly benchmarked last month, scoring 6,608 at the same clock speed. That's quite a gap -- but nothing a little liquid nitrogen won't fix.[Via PC Perspective]
AMD Phenom II CPU roadmap foreshadows potent Spring
Not that AMD's being overly secretive about its forthcoming Phenom II processor, but it hasn't exactly been forthcoming with model names / estimated ship dates, either. And that folks, is why we look to leaks. A recent writeup over on Chinese site HKEPC details the impending chip family by listing over a dozen new CPUs (including two Phenom II X3s and seven Phenom II X4s) that are destined to be announced between CES and June 2009. Not surprisingly, some of the model names aren't -- shall we way, completely original -- with the 3GHz Phenom II X4 940 and 2.8GHz Phenom II X4 920 sharing eerily similar naming schemes with Intel's fresh Core i7. Of course, we're not sticklers for silly things like that -- we just want to see a few slabs of silicon get out the door on time. Is that really too much to ask, AMD?[Via CNET]
AMD overclocks the snot out of Phenom II processors
No, you're not looking at some high-precision, multimeter-laden kegerator; the above is a picture from a recent AMD event in which things apparently got a little out of hand. The company started by talking up its upcoming Dragon platform (Phenom II X4, Radeon 4800 graphics, and 7-series chipset), took a few moments to discuss how its new 45nm chips will use 30-50 percent less power than their predecessors, and then threw all notions of sensibility out the window in an attempt to see just how fast the darned things could go. A Phenom II X4 managed 4GHz with air-cooling, 4.4GHz with a refrigerated setup, and finally a "stable" 5GHz on liquid nitrogen. That's mighty fast, but will the chips be quick enough to tackle Intel's mighty Core i7 when stripped of their fancy-pants cooling appendages? We'll see when they ship early next year.
