Upcoming Intel desktop CPU specs possibly detailed in leak

Earlier this month, a roadmap published by VR-Zone suggested that Broadwell won't make it to the desktop in 2014. Instead, we're due for a Haswell refresh with an updated 9-series chipset. The VR-Zone story matches nicely with information contained in another roadmap that popped up on the web in May. CPU-World has confirmed the validity of some of the details described in that earlier leak, giving us more confidence in its source. That source has now released new information detailing the specifications of upcoming Haswell and Ivy Bridge-E processors.

The spreadsheet covers the full range of Haswell CPUs mentioned in the leaked roadmap, so there's no news on the supposed refresh planned for 2014. There's plenty of data on dual-core Core i3 and Pentium models, though. The duallies will purportedly have 54W TDPs and scale up to 3.6GHz in the Core i3-4340. Haswell-based Pentiums will be nearly as fast, with clock speeds up to 3.3GHz, but they'll lack the Hyper-Threading support available on the Core i3 models. There's also a new quad-core model mentioned, the Core i7-4771, which bumps up the 4770's base frequency by 100MHz to match the 4770K's.

For PC enthusiasts, the most interesting details may be the specifications for upcoming Ivy Bridge-E CPUs. Those are expected in the third quarter, and the top-of-the-line Core i7-4960X will supposedly be clocked at 3.6GHz with a 4GHz Turbo peak. According to the spreadsheet, that chip will be joined by the Core i7-4930K at 3.4/3.9GHz and the Core i7-4820K at 3.7/3.9GHz. Like current Sandy Bridge-E chips, the top models will be six-core, 12-thread parts, while the lowest-end variant maxes out at four cores and eight threads. All three chips will sport quad memory channels, 130W TDPs, and unlocked multipliers.

Intel doesn't appear to have a platform refresh planned for Ivy Bridge-E. All the leaked roadmaps show those CPUs paired with the X79 chipset. Motherboard makers will surely have new products based on that platform, and I'm curious to see how they compare to the latest Z87 hotness. Given Haswell's less-than-stellar overclocking potential, Ivy-E could be a popular choice among PC enthusiasts.
