+ - Sandia upgrades supercomputer benchmarks->

Submitted by PabloSandoval48
PabloSandoval48 (1811646) writes "Exascale supercomputers running a thousand times faster than today's petaflop machines will require newer performance measures, according to Sandia National Laboratories, which announced a 30 member committee effort to define a new standard with Intel, IBM, AMD, NVIDIA, and Oracle. Called Graph 500, a preliminary specification has already been made available to supercomputer makers for testing."

+ - Nvidia describes 10 teraflops processor->

Submitted by PabloSandoval48
PabloSandoval48 (1811646) writes "Nvidia's chief scientist gave attendees at Supercomputing 2010 a sneak peak of a future graphics chip that will power an exascale computer. Nvidia's so-called Echelon system is just a paper design backed up by simulations, so it could change radically before it gets built. Elements of its chip designs ultimately are expected to show up across the company's portfolio of handheld to supercomputer graphics products."

+ - Inside Intel's Sandy Bridge architecture->

Submitted by PabloSandoval48
PabloSandoval48 (1811646) writes "Intel has officially entered the race to heterogeneous computer processors, sketching out the first members of its Sandy Bridge family that will ship before April. The 32nm chips will come in versions with two or four dual-threaded x86 cores and one graphics core on a shared ring interconnect.

The first Sandy Bridge parts are aimed at notebooks, desktops and single-socket servers. Versions with more cores aimed at multi-socket servers will follow later in the year or early in 2012."

+ - Hot Chips: Inside AMD's two new x86 cores->

Submitted by PabloSandoval48
PabloSandoval48 (1811646) writes "A peak inside AMD's Bulldozer and Bobcat cores provides a glimpse at the competitive landscape in x86 processors in 2011 and beyond. The first x86 cores designed from a clean sheet of paper in 10 years will form the underpinning of most of the products AMD will build over the next five to 10 years to compete with archrival Intel in everything from data center servers to ultrathin netbooks."

+ - Poor antenna design may cause iPhone 4 issue->

Submitted by PabloSandoval48
PabloSandoval48 (1811646) writes "Some users are experiencing cellular reception problems with the Apple iPhone 4 that one analyst said could be due to Apple's novel use of the smartphone's frame as an antenna. Apple acknowledged the problem in a statement advising users on how to hold the phone. One teardown expert speculated the problem may be due to what appears to be Apple's decision to embed the phone's cellular and GPS antennas in the metal frame of the case."

+ - Apple's A4 dissected, discussed...and tantalizing ->

Submitted by PabloSandoval48
PabloSandoval48 (1811646) writes "Apple's A4 pr4ocessor is heavily influenced by Apple's long established relationship with Samsung and represents an evolution rather than a revolution in circuit design. A team of experts takes a look at the evidence on A4 in an attempt to determine its origins and the influence of recent Apple acquisitions in the area of chip design."
