A tentative rumor ad mid-day suggests that Apple's anticipated iMac redesign may draw on Intel's mobile Core i7 processors. Most other details aren't provided in the AppleInsider tip, but any release before early 2010 would require that Apple use some or all of the quad-core "Clarksfield" designs on the market and produce the first non-workstation quad-core Macs.
Intel at its second Developer Forum keynote officially unveiled its first Core i7 processors for notebooks. Once codenamed Clarksfield, the quad-core processors share the same Nehalem architecture and 45 nanometer process as the desktop part but are designed to consume much less power, although more at peak than the Core 2 Quad. The top-end Core i7 Extreme consumes 55W where regular quad Core i7 mobile chips will use 45W.
Intel's upcoming Core i7 four-core parts for notebooks, nicknamed Clarksfield, should be much faster per clock cycle compared to their existing Core 2 Quad counterparts based on tests published today. Although normally clocked at just 1.73GHz, the mid-range Core i7-820QM is seen in PCPro benchmarks often coming close to, matching or outperforming the 2.53GHz Core 2 Extreme that costs significantly more than the expected $750 for the newer chip. The edge comes despite extra handicaps on the test system versus the Dell M6400 Covet used for comparison, as the Core i7 system had just half the RAM (4GB), a slower-spinning 5,400RPM hard drive and a more mainstream GeForce GT 240M graphics chip versus the workstation-grade Quadro FX 3700M in the older PC.
HP this morning revived its sleeping Envy label for two new systems targeted at the same slim but high-speed designs as the MacBook Pro. The Envy 13 and 15 are both housed in aluminum-and-black shells and drop the usual optical drive to shed weight and thickness: the 13-inch model is relatively light at just over 3.7 pounds and is 0.8 inches thick, while even the larger 15-inch system is slightly over 5.1 pounds and under an inch. Both also draw on Monster's Beats PC audio to produce better built-in audio than most notebooks, get color accurate displays, and have a MacBook-like trackpad nicknamed the "clickpad" that hides the main button underneath the surface.
Intel today brought its most recent chip architecture into the mainstream with the official start to Lynnfield, its lower-cost but also more advanced desktop platform. The design is headlined by updated Core i7 and new Core i5 processors that build not only the memory controller but also a 16X PCI Express interface directly into the processor die, leaving just a single chip on the mainboard to control the remaining PCI Express slots and other mainboard duties. The gesture cuts lag in talking directly to graphics hardware and reduces the footprint of the system.
HP's impending plans to revamp its notebook line have likely been uncovered in advance today courtesy of a pair of leaks (one, two). Leading the group should be the Pavilion dv8, one of the first systems to use Intel's mobile Core i7; it should be an 18.4-inch desktop replacement with an early 1.6GHz quad-core processor that scales up to 2.8GHz when it can ramp down one or more cores. It's also expected that the system would come with a Blu-ray drive as well as 4GB of RAM and 640GB of storage, likely spread across two disks.
Intel's desktop Core i5 and i7 processors and its matching P55 platform are slated to appear in exactly a week, mainboard producers claimed today. A launch is expected on September 8th that should involve three processors already rumored for next month; these would include the 2.93GHz Core i7 870, 2.8GHz Core i7 860 and 2.66GHz Core i5 750. All of these are quad-core, but only the Core i7 models will have Hyperthreading and support as many as eight program threads at once.
The next revision of Apple's iMac should bring at least a pair of much sought-after features, a teaser rumor puts forward. A veteran source for AppleInsider claims that at least two often-requested features should make it into the next revision. One vague claim says the all-in-one will address a 'wish-list' feature, but another is purported to address the semi-pro audio and visual editing segment.
Intel's first mobile Nehalem processors, known under their Clarksfield codename, have had their launch date pushed to near the start of fall if a rumor proves true. Originally scheduled for the summer, the quad-core chips are now penned in for late September or early October. No reason has been given for the delay by the sources for DigiTimes, although the processors are known to consume large amounts of power.
Intel's Core i7 notebook chips may all consume too much power to be used in anything but high-end notebooks, a late leak indicates. Also known as Clarksfield, the 1.6GHz and 1.73GHz quad-core parts were originally thought to use 35W of peak power, suitable for average and some thin-and-light notebooks, but are now estimated to use 45W and would be ruled out for all but larger, desktop replacement notebooks. The flagship 2GHz Core i7 Extreme would be even more demanding at 55W.
