It's not quite the September 6th announcement we expected, but Intel have finally come clean on their new Core i7-860, i7-870 and Core i5-750 processors, along with a cluster of new Xeon chips. The three new Nehalem-based consumer processors run at 2.80GHz, 2.93GHz and 2.66GHz respectively, with the two Core i7 chips having four cores and eight threads each, while the Core i5 chip - which lacks Hyper Threading support - manages with four cores and four threads.
Each can be flipped into Turbo mode, with the i7-860 scaling up to 3.46GHz, the i7-870 up to 3.6GHz, and the i5-750 up to 3.2GHz. All three have a TDP of 95W, and will be priced - when bought in 1,000 unit quantities - at $284, $562 and $196 each, respectively.
As for the Xeon chips, they range from the 2.4GHz entry-level X3430, through the low-power 45W TDP Xeon L3426 (which can be clocked between 1.86 and 3.2GHz) to the 2.93GHz X3470. Full details in the chart below.
