Intel Launches New Core i5, i7 Haswell Processors Possibly Slated for Retina MacBook Pro Refresh
As detailed by CPU World, Intel has released three new Core i5 chips and three new Core i7 chips that are all successors to the chips currently used in the 13 and 15-inch Retina MacBook Pros. The new processors provide a modest 200 MHz speed boost over existing Haswell chips.
The Core i7-4770HQ chip at 2.2 GHz is a direct replacement for the Core i7-4750 used in the lower-end 2.0 GHz 15-inch Retina MacBook Pro, while the Core i7-4870HQ chip at 2.5 GHz is a direct replacement for the high-end 15-inch Retina MacBook Pro's existing Core i7-4850 chip at 2.3 GHz. The Core i7-4980HQ chip at 2.8 GHz replaces the high-end build-to-order Core-i7 4960 processor at 2.6 GHz.
As for the 13-inch Retina MacBook Pros, the Core-i5 4278U, the Core i5-4308U, and the Core i7-4578U all offer the same 200 MHz jump over the existing Core i5-4258, Core i5-4288, and Core i7-4558 used in the three processors available for the 13-inch Retina MacBook Pro, bringing the low-end up to 2.6 GHz, the mid tier to 2.8 GHz, and the high-end build-to-order option to 3.0 GHz.
Earlier this year, an Intel roadmap revealed direct Haswell successors for the MacBook Air and the iMac, but at the time, there did not appear to be any chips available for a 15-inch Retina MacBook Pro update. The chips in the roadmap designed for the MacBook Air were used in the April refresh as we expected, and the newly released chips are likely destined for an upcoming Retina MacBook Pro update.
As these chips only offer a small 200MHz boost over existing chips, the fall Retina MacBook Pro refresh that has been previously rumored is likely to be only a minor update. A major Retina MacBook Pro update is unlikely until Intel's Broadwell chips are ready in 2015.
Last week, a rumor suggested redesigned 11 and 13-inch MacBook Air models were slated to enter production in August, but it is unclear what chips those machines might utilize as Intel has not yet released another set of Haswell chips suitable for a MacBook Air refresh.
