A few surprises have been revealed in Intel’s CPU database updates today. It turns out that some U-Series processors – the ones we expected only to appear in Ultrabooks – will have HD4xxx graphics. Given that Intel had previously said that Ultrabooks will only have GT3 graphics (HD5000 and Iris HD5100) it could mean that mainstream laptops will also have the option of U-Series SoCs and therefore the possibility of smaller mainboards and S0ix support (for Windows 8 Connected Standy.) It’s confusing and we’re trying to get clarification from Intel but we’ve got an overview of the part numbers, TDP, clocks and graphics below including some Y-Series processors and the real meaning of “6W SDP” which is actually an 11.5W TDP CPU.

Intel® Core™ i7-4500U Processor
4M Cache, 1.8Ghz up to 3.00 GHz Turbo, 15W TDP, HD4400 graphics (1.1 Ghz max clock, single slice GT2)
Intel have previously said that all Ultrabooks will get GT3 graphics processor which leaves us with these Ultrabook-targeted 4th-Gen Core processors
Ultrabook Processors
(assumed, given previous information from Intel.)
Intel® Core™ i3-4158U Processor (28W TDP)
Intel® Core™ i5-4350U Processor (15W TDP, VPro)
Intel® Core™ i5-4288U Processor (28W TDP)
Intel® Core™ i5-4258U Processor (28W TDP)
Intel® Core™ i5-4250U Processor (15W TDP)
Intel® Core™ i7-4650U Processor (15W TDP, VPro)
Intel® Core™ i7-4558U Processor (28W TDP) < High end
Intel® Core™ i7-4550U Processor (15W TDP)
Note that there doesn’t appear to be a low-end Core i3 for Ultrabooks at this stage. (Intel, naturally, can introduce variants later in the Haswell product cycle.)
Non-laptop-style products such as 2-in-1 devices, dockables and convertibles (which may not even be called Ultrabooks as far as we know right now) will take Y-Series processors with single ‘core’ (slice) graphics. These parts won’t offer much graphics improvement over Ivy Bridge but will offer the biggest battery life and small-design advantages and are the ones likely to built to Microsoft’s Connected Standby specs.
Intel® Core™ i3-4010Y Processor (11.5W TDP)
Intel® Core™ i5-4200Y Processor (11.5W TDP)
We note that Intel haven’t made any formal announcements about processor requirements for Ultrabooks this week. The latest Ultrabook definition can be found here.
