The Core i5 4200Y is Intel’s latest high performance tablet processor that has the lowest TDP in Intel's history that stops at 11.5W and Intel claim that for most of the tasks SDP (Scenario Design Power) maxes out at 6W. Most mobile vendors claim that up to 5W is enough for fanless design and Intel is getting toward this holy grail with this architecture.
The Core i5 4200Y has two cores and four threads and works between 1.5GHz and a top turbo frequency of 1.9GHz. It has Intel HD 4200 graphics that clocked between 200MHz and 850MHz. Since this is a system on a chip it comes in a special FCBGA1168 socket, supports 4 USB 3.0 ports, SATA 6.0 Gb/s times four and some nice features such as Turbo Boost 2.0.
The runner up, designed to fit the same thermal envelope, is the Core i3 4010Y. It has 3MB cache two cores and four threads and 1.3GHz frequency. This chip does not support turbo core overclocking and stays at the same max clock of 1.3GHz, making it much less attractive. It is also scheduled to launch in Q3 2013, it has an SDP of 6W and TDP of 11.5W. It has the same HD 4200 graphics with 200MHz base clock and maximum clock of 850MHz. The recommended customer price of the Core i3 4010Y is $304, while the recommended price of a tray Core i5 4200Y stays at the same 304 USD, which makes no sense and there’s probably more to the specs than meets the eye.
To refresh your memory Intel claims that TDP is “Thermal Design Power (TDP) represents the near maximum power a product can draw for a thermally significant period while running commercially available software.” while a definition of a new invention called SDP is as follows: “Scenario Design Power (SDP) is an additional thermal reference point meant to represent mainstream touch-first usages. It balances performance and mobility across PC and tablet workloads to extend capabilities into thin, thermally-constrained designs.”
Tablets and notebooks based on new Y-series Haswells should show up in the latter part of Q3 2013, probably closer to the holiday season, but we have to admit that Haswell based Core i5 4200Y sounds like a great chip that needs very little power indeed.
