The difference between [the P4] and the [Athlon] die size is frigging huge - AMD's Jerry Sanders III
CHIPMAKER Intel's high end quad-core Core i7 QM mobile processors are getting another airing thanks to Dell despite not having been officially announced yet.
The Intel quad-core Core i7-740QM and Core i7-840QM chips have been spotted on Dell's US online store as configurable options for laptops. Click on "personalise my Dell" and the "select a processor" tab has two options to choose either a Core i7-740QM or Core i7-840QM from the menu.
Dell is selling its non-existent Intel Core i7-740QM for £57, bizarrely cheaper than the £62 for the previous Core i7-720QM. At £474, the Core i7-840QM is more expensive than the £428 for the earlier Core i7-820QM. With the huge price differentials and higher cost for an older processor, we reckon Dell's price list is off the mark.
Dell lists the Core i7-740QM as running at 1.73GHz with four cores and eight threads, including a 6MB cache and turbo boost up to 2.93Ghz. The more powerful Core i7-840QM runs at 1.86GHz with four cores and eight threads, an 8MB cache and 3.2GHz turbo boost.
Someone at Dell might be in trouble for putting that information up. We're guessing they'll be getting the same treatment someone at HP went through last week. We reported that HP's high-end Envy laptops were publicised as offering a Core i7-740QM or Core i7-840QM processor.
Both sightings report exactly the same specifications so they must be onto something. µ
