Intel said at CES 2021 that it will release 5 CPU platforms this year, including Rocket Lake, Jasper Lake, Ice Lake Xeon, Alder Lake, and Tiger Lake-H. Now that the first three CPU platforms have been released, Tiger Lake-H will be available soon. It will be released within a period of time, and Alder Lake will have to wait until Q3 or even the end of the year. However, according to the latest news, Intel will also be preparing to launch a product called Tiger Lake Refresh this year.
According to AnandTech, this Tiger Lake Refresh is actually an updated version of Tiger Lake-U. This processor is for a thin and light notebook designed for 15W to 28W TDP. The Core i7-1195G7 and Core i5-1155G7 have leaked before maybe Tiger Lake Refresh.
Tiger Lake-U was released in September 2020. It adopts Intel 10nm SuperFin process. There are 4 Willow Cove cores inside. The highest core frequency can reach 4.8GHz. The core is up to 96 execution units of the new Xe-LP graphics technology. Lake-U processor products basically use DDR4-3200 or LPDDR4X-4266 memory. In fact, Intel once said that Tiger Lake-U supports LPDDR5-5400, but there is no such matching product yet.
Tiger Lake Refresh will be released in the third quarter of this year, and at this point in time, Alder Lake should be released. Why do we need Tiger Lake Refresh?
Possibility one is as a transition platform. Although Alder Lake may be released in the third quarter of this year, in fact, the product launch may not be so fast. It is very likely to be seen in the fourth quarter or even next year, and Tiger Lake Refresh to act as an excessive product during this period.
Possibility two is related to LPDDR5 memory, that is, Tiger Lake Refresh may be used with LPDDR5 memory. All current Tiger Lake-U products use DDR4 or LPDDR4X. If you use LPDDR5-5600, the bandwidth will be higher than the current LPDDR4X-4266. An increase of 31% can further explore the performance of the processor, and Alder Lake also supports LPDDR5, allowing OEM manufacturers to adapt early.
In addition, AnandTech said that Tiger Lake Refresh is only for Tiger Lake-U, but Tiger Lake-H35 actually has new models leaked before, namely Core i7-11390H and Core i5-11320H. After all, Tiger Lake-U and Tiger Lake-H35 use the same chip, so it’s no surprise that Tiger Lake-H35 also has new members.
