Nvidia and Advanced Micro Devices' ATI division are taking different approaches to graphics processing in the next generations of their products. Both strategies have strengths and weaknesses, and I think it's too soon to pick the eventual winner in this long-running fight.
Before I get into my analysis, I should say that Nvidia paid me to write a white paper on the implications of its new GPU architecture (code-named Fermi) for high-performance computing applications. The white paper was released as part of the Fermi launch event at Nvidia's GPU Technology Conference last week.
Nvidia also paid for white papers from two other well-known microprocessor analysts, Nathan Brookwood of Insight64 and my friend and former colleague Tom Halfhill of Microprocessor Report. UC Berkeley professor David Patterson wrote a fourth white paper, and Nvidia wrote one of its own. All of these works take a different approach to the subject; all are worth reading if you need to understand what Fermi is all about.
In short, I think the Fermi architecture has been more thoroughly white-papered than any graphics chip design in history. All five of these documents are available on the Fermi home page on Nvidia's Web site, and just in case that page is moved or changed, you're welcome to take advantage of my own mirror of my white paper.
I've spent much of the last several days reading these documents plus David Kanter's excellent article on Fermi over on his Real World Technologies site. David managed to get some details on Fermi that Nvidia didn't give to the rest of us.
I've also had time to go through the coverage of ATI's recent launch of the RV870, which is what Nvidia's Fermi-based chips will be competing against. The first of Nvidia's chips bears the internal code name of GF100, and it's huge. Here's a life-size photo:… Read more
The Yukyung Viliv lineup ultraportable of mini-computers is, in a way, a bit of a throwback to the days when UMPCs and MIDs ruled the pocket-gadget landscape and laptops were bulky and expensive and didn't have any great battery power to speak of. Back in the days of the OQO and the Samsung Q1, you didn't expect an ultraportable to have the same productivity power as a full-fledged computer...you were, in fact, happy when it just did one or two things right. Those days are over, though. For $300 you can now get a Netbook which, while … Read more
HP announced its fall lineup today, which included new Windows 7 laptops, an Ion-powered Netbook, SmartMedia network storage products, an all-in-one desktop, and an assortment of business-centric monitors.
HP gets an Ion-powered HD Netbook With a Nvidia Ion processor and a 1,366x768 11.6-inch screen, the HP Mini 311 looks to be the type of souped-up HD Netbook we've been waiting for. (Posted in Crave by Scott Stein) September 14, 2009, 9:06 p.m. PDT
HP 13-inch laptops bring on aluminum and affordability Just in time for Windows 7 comes HP's new Windows 7-preinstalled 13-inch thin-and-lights. (… Read more
I reviewed the HP MediaSmart LX190 a while ago, and though I wished it had more storage, I still gave it the editors' choice award for its great performance. And now both the storage and performance have been increased.
HP launched Monday the two new models of the MediaSmart EX490 and MediaSmart EX495 Home Servers, offering increased capacity, high-performance processors, and more features.
Similar to previous models, both new servers are based on the Microsoft Windows Home Server platform. However, they both now have a refined user interface and a Web-based home page that further facilitates accessing and using the … Read more
Wanting to build excitement leading up to the 2009 Frankfurt auto show, Rolls-Royce has released a slew of details and photos of its upcoming Ghost (formerly known as the 200EX Concept). As expected, the Ghost features umbrellas hidden in the door jambs, self-righting "RR" wheel caps, and a motorized Spirit of Ecstacy hood ornament, but we're most interested in what's happening under the hood and in the cabin.
Under the brushed metal hood is a new direct-injected 6.6 liter twin-turbo V12 engine, sending 563 horsepower and 575 pound-feet of torque through an eight-speed, shift-by-wire, automatic … Read more
Casio's going full force after consumers shopping for digital cameras in the $100-$200 price range. First, the company announces the Exilim EX-Z450 and EX-Z90, $199.99 and $149.99, respectively. And then Monday, it announces the $179.99 EX-Z280 and $119.99 EX-Z33.
The Z280 (pictured right) is a 12-megapixel ultracompact with an f2.6-5.9 26-104mm-equivalent wide-angle lens with a 4x zoom, sensor-shift image stabilization, 2.7-inch LCD, and Casio's newest image processing engine featuring a dual-processor design for lower power consumption and better photo results. It also gives you 720p HD-quality video capture and the … Read more
How would you like a single-chip microprocessor with more than four times the performance (on some applications) of Intel's best Core i7?
Then consider that up to 32 of these chips can be directly connected to form a single server, achieving four times the built-in scalability of Intel's next-generation Nehalem-EX processor.
That's IBM's widely anticipated Power7, which it described at last week's Hot Chips conference. But if you're interested, you'd better be prepared to spend a lot more than four times as much per chip. IBM isn't talking about pricing, but large … Read more
If you've got a point-and-shoot with face detection, you may have noticed that the feature's handy if you're shooting faces, but if left on when shooting other subjects the autofocus system is less than accurate. Casio's apparently fixed this with a new Intelligent AF found in its 12-megapixel Exilim EX-Z450 and EX-Z90 ultracompact cameras announced Tuesday.
The AF will detect faces, as well as "non-human photo subjects," so that an animal, flower, or alien invader will be in focus and properly exposed.
