Gulftown versus SandyBridge

X-Bit Labs pits Intel's two superstars against each other, the mighty but slightly elderly i7-990X Extreme Edition  and the brand new i7-2600K.  They both have roughly the same 3.4GHz speed but achieve it in different ways, with the 990X running 133MHz with a 26x multiplier and the 2600K adds a 34x multiplier to the 100MHz base and both vary their speed depending on tasks.  Turbo mode is also mostly the same, with the 2600K reaching a slight higher speed with it's 4/8 cores.  Can the extra cores and enthusiast level motherboard on the 990X push the performance past the new technology in SandyBridge?  Find out here.

"Intel started integrating the new Sandy Bridge processor microarchitecture not in the upper price segment, but in the mainstream LGA1155. This resulted in internal competition between the new LGA1155 and the old LGA1366 processors. So, which one will win in this round, the progressive Sandy bridge or the previous-generation Gulftown?"

Of Linux and low end SandyBridge graphics performance

Subject: Processors | March 31, 2011 - 12:25 PM |
Tagged:

Any difficulties that Phoronix have encountered running Linux on SandyBridge platforms seem to have been taken as a personal insult and a challenge to be overcome.  They've been working hard testing the hardware to its current limits on Linux and have recently started on the graphical testing.  Drop by to see how well the support for Linux has been improved.

"On Wednesday we published our first compute performance numbers for the Core i3 2100, Intel's lowest-end "Sandy Bridge" processor at this point. This ~$125 USD processor was a step-up from the previous generation Clarkdale CPUs (roughly the Core i3 530), but obviously the Core i5 2500K was still a great deal faster. How's the Sandy Bridge graphics performance though with this low- end CPU? That is the focus of today's tests."

Surprise Bulldozer; a sneak peek at the unreleased AMD processors

Subject: Processors | March 22, 2011 - 06:25 PM |

Phoronix noticed something very interesting on their OpenBenchmarking.org project.  One submitter seems to be benchmarking a "AMD Eng Sample ZS182045TGG43_28" which appears to be one of the unreleased 16-core Interlagos Opterons.  The 32 core, 1.8GHz beats Intel's newest on the Ray Tracing benchmark that was used to test performance and it shows great promise on two other benchmarks that were verified as valid.  Some techies will also be very pleased that the new chips obviously have no problems with Linux.

"Lately we have been talking a lot about Intel's latest Sandy Bridge processors under Linux due to their very competitive performance and interesting graphics abilities, but on the AMD side there has not been too much to talk about. On the low-end there is the intriguing Fusion APUs, but on the high-end they don't have an answer to Sandy Bridge until delivering their new "Bulldozer" products closer to the summer. Fortunately, we have the first Linux scoop and performance benchmarks from engineering samples of their 16-core Interlagos server chip."

The Core i7 990X Extreme would like a word with you

Subject: Processors | March 4, 2011 - 01:06 PM |
Tagged:

Core i7-990X is a little upset that no one is paying attention to it.  Instead everyone is focused on what is a mid-range series of processors named SandyBridge that hangs out with a friend that doesn't like storage devices.  It is after all the fastest that Intel offers and has support for a lot of features that SB won't have until the high end series is finally released. 

Check out The Tech Report to see Intel's new flagship CPU in action.

 

 

"I hate to brag, but with six cores at 3.46GHz, a Turbo peak of 3.73GHz, 12MB of L3 cache, and three channels of DDR3 memory, I'm kind of a big deal. Add in the fact that my upper multipliers are unlocked so that I can be overclocked, and you can see why my asking price is one dollar short of a grand. If you still don't get it, just know that the valedictorian at your high school would probably have a nerdgasm over me. That's the sort of response I tend to provoke among dudes who know what I am. And ladies, of course. Both of them are pretty excited, too."

I have to admit that sometimes AMD doesn't come off as the most modern and hip company when it comes to advertising, but today they did something quite "fresh" and humorous.  When the door bell rang at 8am this morning and I found a small cubed package on the step, I honestly wasn't expecting anything.  Inside I found a coffee mug with the label "I (heart) APU" on it filled with small chocolates. 

Unfortunately my mug was in about a dozen pieces, but hey, the candy was still good!

NVIDIA settles with Intel for $1.5 billion and cross-licensing

Subject: Processors | January 10, 2011 - 05:37 PM |

It has been an interesting evening in the world of high tech business as the post-CES silence was broken by two news-worthy stories.  AMD's CEO gets kicked to the curb and now this: NVIDIA is settling its legal issues with Intel for $1.5 billion paid over five annual payments in exchange for a cross-licensing deal during that time.  For all the talk from each company's respective CEOs over the years of this dispute, it all comes down to some simple payments and we'll likely not hear of it again until the renewal season is met. 

The patents are really going one way here - Intel gets access to NVIDIA's portfolio of goodies in exchange for this payment.  Does NVIDIA get access to Intel information?  Likely, but it doesn't look like the green team has any plans to use it:

"We have said many times that we have no intentions to develop chipsets for Intel processors," said NVIDIA CEO Jen-Hsun Huang.  "We have no intentions of building x86 processors." 

Well there you go - NVIDIA doesn't plan on to work on a processor compatible with x86 technology and instead is going to push forward with its Project Denver that will attempt to bring the ARM architecture to larger platforms like tablets, notebooks and even desktops.  That much I have always believed - x86 is big, complex and not the best tool for the job in terms of mobile devices. 

What we might have expected was a return of NVIDIA to the world of Intel platform core logic design, but that sounds like its out as well.  I am guessing that restarting the division inside the company would take longer than it is worth and with the continued rise of Intel's desktop-class processor graphics, going down that road is less and less profitable.

Intel to Pay NVIDIA Technology Licensing Fees of $1.5 Billion

New Six-Year Cross-License Renews Previous Agreement

SANTA CLARA, CA, Jan 10, 2011 (MARKETWIRE via COMTEX) --

NVIDIA announced today that it has signed a new six-year cross-licensing agreement with Intel.

For the future use of NVIDIA's technology, Intel will pay NVIDIA an aggregate of $1.5 billion in licensing fees payable in five annual installments, beginning Jan. 18, 2011.

NVIDIA and Intel have also agreed to drop all outstanding legal disputes between them.

"This agreement signals a new era for NVIDIA," said Jen-Hsun Huang, NVIDIA's president and chief executive officer. "Our cross license with Intel reflects the substantial value of our visual and parallel computing technologies. It also underscores the importance of our inventions to the future of personal computing, as well as the expanding markets for mobile and cloud computing."

Under the new agreement, Intel will have continued access to NVIDIA's full range of patents. In return, NVIDIA will receive an aggregate of $1.5 billion in licensing fees, to be paid in annual installments, and retain use of Intel's patents, consistent with its existing six-year agreement with Intel. This excludes Intel's proprietary processors, flash memory and certain chipsets for the Intel platform.

The existing agreement is to expire March 31, 2011.

Pursuant to U.S. GAAP, a portion of the proceeds will be accounted for and attributed to the settlement of prior legal claims. This amount, which NVIDIA anticipates to be less than $100 million, will be included in the company's fourth-quarter results.

The balance of the licensing fees will be accounted for on a straight-line basis over the six-year term of the agreement. Accordingly it is anticipated that this would amount annually to approximately $233 million of operating income and an increase in net income of $0.29 per diluted share, on a full year basis.
