Ivy Bridge mobile CPU specifications exposed

More details have leaked out on Intel's upcoming Ivy Bridge CPUs. We learned about the desktop side of Sandy Bridge's successor last week, and now the mobile part of the picture has been filled in. CPU World has summarized the specifications of no fewer than eight notebook-bound Ivy Bridge CPUs.

The first quad-core members of the mobile Ivy Bridge family will reportedly arrive in April. Three models will supposedly be available at that time, including a Core i7-3920XM with a 3.8GHz Turbo peak and a 55W thermal envelope. Obviously, that ain't going in an ultrabook. Neither are the other two quad-core parts, which have 45W thermal envelopes and only slightly slower clock speeds. All of the quad-core chips support Hyper-Threading.

Intel's threading magic will also infiltrate a collection of dual-core Ivy Bridge CPUs due out in May. According to CPU World, three of those chips have 35W thermal envelopes, while two have TDP ratings of just 17W. The fastest 17W chip is the Core i7-3667U, which purportedly boasts a 2GHz base clock speed and a 3.2GHz Turbo peak. For reference, the best Sandy Bridge part with a 17W thermal envelope is the Core i7-2677M, which is clocked at 1.8GHz with a 2.9GHz Turbo ceiling.

The May arrival of the first ultrabook-worthy Ivy Bridge CPUs should ensure that Computex is teeming with razor-thin notebooks. The trade show takes place from June 5-9 in Taipei, Taiwan, and we'll have someone on the ground to cover all the gory details.
